How to reload list resource bundle in ADF 12c - oracle-adf

I fail to reload my resource bundle class to reflect the changed translations (made my end-user) on page. Although getContent method executes and all translations as key/value fetched from database and object[][] returned from getContent method successfully. this happens after each time I clear the cache and refresh the jsf page through actionListener.
ResourceBundle.clearCache();
Also I tried to use the below and got the same result.
ResourceBundle.clearCache(Thread.currentThread().GetContextClassLoader());
Why WLS always see the old one? Am I miss something?
versions: 12.2.1.1.0 and 12.2.1.3.0

The end user - after making the translations and contributing to the internationalization of the project, the translations are saved to the database,
The process to inforce these operations are done through the following steps:
Create a HashMap and load all the resource key/vale pairs in the map
from the database:
while (rs.next()) {
bundle.put(rs.getString(1), rs.getString(2));
}
Refresh the Bundle of your application
SoftCache cache =
(SoftCache)getFieldFromClass(ResourceBundle.class,
"cacheList");
synchronized (cache) {
ArrayList myBundles = new ArrayList();
Iterator keyIter = cache.keySet().iterator();
while (keyIter.hasNext()) {
Object key = keyIter.next();
String name =
(String)getFieldFromObject(key, "searchName");
if (name.startsWith(bundleName)) {
myBundles.add(key);
sLog.info("Resourcebundle " + name +
" will be refreshed.");
}
}
cache.keySet().removeAll(myBundles);
Getthe a String from ResourceBoundle of your application:
for (String resourcebundle : bundleNames) {
String bundleName =
resourcebundle + (bundlePostfix == null ? "" : bundlePostfix);
try {
bundle = ResourceBundle.getBundle(bundleName, locale, getCurrentLoader(bundleName));
} catch (MissingResourceException e) {
// bundle with this name not found;
}
if (bundle == null)
continue;
try {
message = bundle.getString(key);
if (message != null)
break;
} catch (Exception e) {
}
}

dynamically populate VoiceCommand PhraseList, Error VoiceCommandSet not found

I am looking for a way to dynamically populate my VCD file. I have a Code snippet from the Windows documentation that reads as follows:
Windows.ApplicationModel.VoiceCommands.VoiceCommandDefinition.VoiceCommandSet commandSetEnUs;
if (Windows.ApplicationModel.VoiceCommands.VoiceCommandDefinitionManager.
InstalledCommandSets.TryGetValue(
"AdventureWorksCommandSet_en-us", out commandSetEnUs))
{
await commandSetEnUs.SetPhraseListAsync(
"destination", new string[] {“London”, “Dallas”, “New York”, “Phoenix”});
}
But, when I put this into my version of App.OnActivated() Visual Studio shows an error saying that VoiceCommandSet is not contained in "Windows.ApplicationModel.VoiceCommands.VoiceCommandDefinition". My questions are:
Am I doing that in the wrong place? Do you know any example projects, that show how to do this properly? (I looked into Adventure Works, but didn't find these lines over there) Or am I missing some references, that I'm not aware of?
public async Task UpdateDestinationPhraseList()
{
try
{
// Update the destination phrase list, so that Cortana voice commands can use destinations added by users.
// When saving a trip, the UI navigates automatically back to this page, so the phrase list will be
// updated automatically.
VoiceCommandDefinition commandDefinitions;
string countryCode = CultureInfo.CurrentCulture.Name.ToLower();
if(countryCode.Length == 0)
{
countryCode = "en-us";
}
if (VoiceCommandDefinitionManager.InstalledCommandDefinitions.TryGetValue("AdventureWorksCommandSet_" + countryCode, out commandDefinitions))
{
List<string> destinations = new List<string>();
foreach (Model.Trip t in store.Trips)
{
destinations.Add(t.Destination);
}
await commandDefinitions.SetPhraseListAsync("destination", destinations);
}
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine("Updating Phrase list for VCDs: " + ex.ToString());
}
}

Get velocity template from database in Springboot

I have to get velocity templates from database in Spring boot and Spring data project.I have not tried any code yet as I am new to all technologies(Velocity, Spring boot and data) and not finding anything on google. Does anybody tried here to get template from db, please suggest me some links or anything else which i can refer?
Update: I have binding classes in db (in grails) and I have to access process method from java .In db class is ,
class bindingSubject {
def log
def process = { pub,listForMail ->
def mapBinding = [:]
def fund
def perimeters = pub.sub.entities
perimeters.each(){ entity ->
if (fu == null){
if (entity instanceof S)
fu = entity.fu
if (entity instanceof Fund)
fu = fu
}
}mapBinding.entity = fu.name return mapBinding
}
}
and java code written to
-> Load script
mapScriptClass = new HashMap<String, Object>();
if (script != null) {
if (mapScriptClass.get(name) == null) {
GroovyCodeSource groovySource = new GroovyCodeSource(script,name,"");
GroovyClassLoader classLoader = new GroovyClassLoader(this.getClass().getClassLoader());
// Load string as Groovy script class.
Class scriptClass = classLoader.parseClass(groovySource);
try {
Object classInstance = scriptClass.newInstance();
ApplicationContext ctx = (ApplicationContext)ServletContextHolder
.getServletContext().getAttribute(ApplicationAttributes.APPLICATION_CONTEXT);
ctx.getAutowireCapableBeanFactory().autowireBeanProperties(classInstance, AutowireCapableBeanFactory.AUTOWIRE_BY_NAME, false);
mapScriptClass.put(name, classInstance);
return classInstance;
To call process method from db(in grails this works , how to do it in java?)
Object scriptClass = loadScriptService.getScriptClass("scriptBindingSubject"+templateMail.getId(),
templateMail.getScriptBindingSubject());
if (scriptClass != null) {
try{
bindingSubject = scriptClass.process(pub,subMail);
}
now i am not sure how to call process method from java(to db) to bind properties
Thanks.
As you write, the templates are stored in the database.
So you need to read them (using JDBC or JPA) and depending on how they are stored, you will get a String, char[] or byte[].
You can convert all of them into a java.io.Reader like
CharArrayReader, StringReader,
how this can be done for a byte[] you can see in this tutorial
SimpleTemplateEngine has a method
createTemplate(Reader reader)
that finally creates the template for the reader.
Hope that helps.

WebAPI EF update 30,000 rows of data is very slow

I am trying to have my asp.net WebAPI web service read a .csv and update a database using Entity Framework. The .csv file is about 20,000-30,000 rows.
As of now I am using a TextfieldParser to read the .csv, each row of the .csv file I create a new object, then add object to the EF context.
Once it's done adding all rows to the context, then I call db.SaveChanges();
Watching the console I noticed it calls an update statement for each row... which takes a long time. Is there a better more efficient way to accomplish this?
if (filetype == "xxx")
{
using (TextFieldParser csvReader = new TextFieldParser(downloadFolder + fileName))
{
csvReader.SetDelimiters(new string[] { "," });
csvReader.HasFieldsEnclosedInQuotes = true;
int rowCount = 1;
while (!csvReader.EndOfData)
{
string[] fieldData = csvReader.ReadFields();
//skip header row
if (rowCount != 1)
{
var t = new GMI_adatpos
{
PACCT = fieldData[3]
};
db.GMI_adatpos.Add(t);
}
rowCount++;
}
}
}
db.SaveChanges();
This issue is very common,
In your case, we can split it into two category:
Add vs AddRange Performance
Write & database round-trip
Add vs AddRange Performance
The Add method will try to detect change every time you add a new record while the AddRange only does it once. Detecting changes every time can take several minutes.
This issue is very easy to fix, simply create a list, add the entity to this list instead and use AddRange with the list at the end.
List<GMI_adatpo> list = new List<GMI_adatpo>();
if (filetype == "xxx")
{
using (TextFieldParser csvReader = new TextFieldParser(downloadFolder + fileName))
{
csvReader.SetDelimiters(new string[] { "," });
csvReader.HasFieldsEnclosedInQuotes = true;
int rowCount = 1;
while (!csvReader.EndOfData)
{
string[] fieldData = csvReader.ReadFields();
//skip header row
if (rowCount != 1)
{
var t = new GMI_adatpos
{
PACCT = fieldData[3]
};
list.Add(t);
}
rowCount++;
}
}
}
db.GMI_adatpos.AddRange(list)
db.SaveChanges();
Write & Database round-trip
Everytime you save a record, you perform a database round-trip. So if you insert average 30,000 record, you perform 30,000 database round-trip which is insane!
Disclaimer: I'm the owner of the project Entity Framework Extensions
This library allows to perform:
BulkSaveChanges
BulkInsert
BulkUpdate
BulkDelete
BulkMerge
You can either call BulkSaveChanges instead of SaveChanges or create a list to insert and use directly BulkInsert instead for even more performance.
BulkSaveChanges Solution (Way faster than SaveChanges)
db.GMI_adatpos.AddRange(list)
db.SaveChanges();
BulkInsert Solution (Fastest than BulkSaveChanges but do not save related entities)
db.BulkInsert(list);
Because the number of items added to the DbContext is very high, ram space is gradually filled, and operation is very slow. Therefore is better that after a few records (ex 100), calling SaveChanges Methods and renew DbContext.
if (filetype == "xxx")
{
using (TextFieldParser csvReader = new TextFieldParser(downloadFolder + fileName))
{
csvReader.SetDelimiters(new string[] { "," });
csvReader.HasFieldsEnclosedInQuotes = true;
int rowCount = 1;
while (!csvReader.EndOfData)
{
if(rowCount%100 == 0)
{
db.Dispose();
db.SaveChanges();
db = new AppDbContext();//Your DbContext
}
string[] fieldData = csvReader.ReadFields();
//skip header row
if (rowCount != 1)
{
var t = new GMI_adatpos
{
PACCT = fieldData[3]
};
db.GMI_adatpos.Add(t);
}
rowCount++;
}
}
}

How to know the order of update with Domain context SubmitChanges?

Suppose I have 3 entities generated from EF, say tab1, tab2 and tab3. In SL app, I call SubmitChanges to save data to DB, all changes will be process by WCF and EF automatically.
Question is: how can I know the order of Update operation in Database?
I need to know this because I have triggers on those tables and need to know the order of the updating.
One thing you can do is to override the PeristChangeSet() in your DomainService and manually control the order of saves. Just do nothing in your regular update/insert statements. Here's some pseudocode for a saving a document exmmple to explain my answer:
[Insert]
public void InsertDocument(MyDocument objDocument) { }
[Update]
public void UpdateDocument(MyDocument objDocument) { }
protected override bool PersistChangeSet()
{
try {
// have to save document first to get its id....
MyDocument objDocumentBeingSaved = null;
foreach (ChangeSetEntry CSE in ChangeSet.ChangeSetEntries.Where(i => i.Entity is MyDocument)) {
var changedEntity = (MyDocument)CSE.Entity;
objDocumentBeingSaved = documentRepository.SaveDocument(changedEntity);
break; // only one doc
}
if (objDocumentBeingSaved == null)
throw new NullReferenceException("CreateDocumentDomainService.PersistChangeSet(): Error saving document information. Document is null in entity set.");
// save document assignments after saving document object
foreach (ChangeSetEntry CSE in ChangeSet.ChangeSetEntries.Where(i => i.Entity is DocumentAssignment)) {
var changedEntity = (DocumentAssignment)CSE.Entity;
changedEntity.DocumentId = objDocumentBeingSaved.Id;
changedEntity.Id = documentRepository.SaveDocumentAssignment(objDocumentBeingSaved, changedEntity);
}
// save line items after saving document assignments
foreach (ChangeSetEntry CSE in ChangeSet.ChangeSetEntries.Where(i => i.Entity is LineItem)) {
var changedEntity = (LineItem)CSE.Entity;
changedEntity.DocumentId = objDocumentBeingSaved.Id;
changedEntity.Id = documentRepository.SaveLineItem(objDocumentBeingSaved, changedEntity);
}
documentRepository.GenerateDocumentNumber(objDocumentBeingSaved.Id);
}
catch {
// ....
throw;
}
return false;
}

Is my LDAP syntax wrong in search filter

This is my first attempt in trying to query our LDAP server for AD info. When I am trying to query the LDAP server here is what I'm trying to retrieve:
I am trying to retrieve all active employees with a countlimit of 500 records whose displayname starts with "sav", has an email address and has a userAccountControl attribute of 512. The problem I'm encountering is that I'm only getting back 8 records total. I should literally be getting back at least 10 records.
I did a separate search on the 2 records that were NOT retrieved in my search and each had an email address and a userAccountControl value of 512. So I'm not sure why those 2 records were missing.
I'm sure I've done something wrong in my syntax but I cannot find what it is. Any HELP/DIRECTION would be appreciated. Thank you.
After googling I've defined the SEARCH FILTER as:
String searchFilter = "(&(objectClass=user)(displayname="+displayname+"*"+")(mail=*)(userAccountControl=512))";
Please see my complete method below:
public List<String> getAutocompleteEmpRecordsList(String displayname, LdapContext ctx) {
List<String> activeEmpAttributes = new ArrayList<String>();
Attributes attrs = null;
int count = 0;
int empEmailAddrLen = 0;
try {
SearchControls constraints = new SearchControls();
constraints.setCountLimit(500);
constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
String[] attrIDs = {"displayname", "mail", "userAccountControl"};
constraints.setReturningAttributes(attrIDs);
String searchFilter = "(&(objectClass=user)(displayname="+displayname+"*"+")(mail=*)(userAccountControl=512))";
NamingEnumeration answer = ctx.search("OU=Standard,OU=Users,DC=xxx,DC=org", searchFilter, constraints);
if (answer != null) {
while (answer.hasMore()) {
attrs = ((SearchResult) answer.next()).getAttributes();
if (attrs.get("displayname") != null) {
int empNameLen = attrs.get("displayname").toString().length();
activeEmpAttributes.add(attrs.get("displayname").toString().substring(13, empNameLen));
}
count++;
ctx.close();
}
}
else {
throw new Exception("Invalid User");
}
System.out.println("activeEmpAttributes: " + activeEmpAttributes);
System.out.println("count: " + activeEmpAttributes.size());
} catch (Exception ex) {
ex.printStackTrace();
}
return activeEmpAttributes;
}
You may be confusing displayname attribute and cn attribute.
On Windows server you've got a command line tool called LDIDIFDE.EXE which can allow you to test your filter.
ldifde -f datas.ldf -d "OU=Standard,OU=THR Users,DC=txhealth,DC=org" -r "(&(objectClass=user)(displayname=sav*)(mail=*)(userAccountControl=512))"
ldifde -f datas.ldf -d "OU=Standard,OU=THR Users,DC=txhealth,DC=org" -r "(&(objectClass=user)(cn=sav*)(mail=*)(userAccountControl=512))"
In the User and computer MMC you can also test your filter.
Start User and computer Active-Directory :
Right buton on registered request :
Choose personalize search, you've got an helper tab for common attributes :
You can choose personalized tab for technical attributes
You can test en copy the resulting LDAP filter (you don't need the double (& one is enough):
Can you post your userAccountControl, displayName, and mail values for the two excluded users?
FWIW the medial search on displayName would run alot faster if you add a tuple index to it.
I downloaded a free AD tool to view all in AD that I needed and it showed me that the data was not the problem but I was just not hitting all the OU's that I needed because there is NOT just 1 OU where all our users are stored.
Consequently, after googling some more I found a page on the Oracle site regarding LDAP and I changed my LDAPContext to DirContext for my connection to do searches within the directory as well as using this context's REFERRAL and set the value to "follow" to avoid the PartialSearchException.
I thought I'd post my findings just in case some other newbie ran into the same issue.
If you see a downside to the changes I made please let me know. Regards.
Here is my corrected code:
public List<String> getAutocompleteEmpRecordsList(String displayname, DirContext ctx) {
List<String> activeEmpAttributes = new ArrayList<String>();
Attributes attrs = null;
int count = 0;
int empEmailAddrLen = 0;
try {
SearchControls constraints = new SearchControls();
constraints.setCountLimit(500);
constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
String[] attrIDs = {"displayname", "mail", "userAccountControl"};
constraints.setReturningAttributes(attrIDs);
String searchFilter = "(&(objectClass=user)(displayname="+displayname.trim()+"*"+")(mail=*)(userAccountControl=512))";
NamingEnumeration answer = ctx.search("DC=xxx,DC=org", searchFilter, constraints);
if (answer != null) {
while (answer.hasMore()) {
attrs = ((SearchResult) answer.next()).getAttributes();
if (attrs.get("displayname") != null) {
int empNameLen = attrs.get("displayname").toString().length();
activeEmpAttributes.add(attrs.get("displayname").toString().substring(13, empNameLen));
}
count++;
ctx.close();
}
}
else {
throw new Exception("Invalid User");
}
System.out.println("activeEmpAttributes: " + activeEmpAttributes);
System.out.println("count: " + activeEmpAttributes.size());
} catch (Exception ex) {
ex.printStackTrace();
}
return activeEmpAttributes;
}
Thanks anyway.
