I'd like to support serde of POJO classes that include java.time.Instant member fields. As such, I was happy to find a Jackson module that is designed precisely for this use case:
https://github.com/FasterXML/jackson-modules-java8
Unfortunately I am unable to register the JavaTimeModule as follows because it fails to compile given I need to import a flink-shaded jackson2 jar that includes JavaTimeModule but am unable to find it (eg in maven-central):
private ObjectMapper mapper = new ObjectMapper()
.enable(MapperFeature.ACCEPT_CASE_INSENSITIVE_ENUMS)
.registerModule(new JavaTimeModule());
Thoughts?
thx,
james
It's not entirely clear how you currently use jackson. But in general, there is no need to include flink-shaded-jackson in your user jar. In fact, it is heavily discouraged. The whole point of shading is that you can use your own version without class conflicts. So simply add jackson with the respective module to your gradle project and use it as is.
Now if you use any given format/connector of Flink that uses the flink-shaded-jackson, then you need to shade the time module in the same fashion, unfortunately. You can use the json schema module as a reference.

HI I'm able to smart import Projects in ODI using SDK. but i'm unable to use the predefined method which sets actions like merge, create copy, ignore, reuse, while importing the projects.
Please help me to implement the below method,
setMatchedFCODefaultImportAction(java.lang.String pFCOObjType, int pSmartImportAction)
by using below method i'm directly importing projects.
importObjectsFromXml (fnameAndPath, ExportKey, ExportWithoutCipherData);
I want to implement above mentioned actions, please help me.
thanks
Unfortunately you can not use setMatchedFCODefaultImportAction to specify the action for a specific object like a project as in your code :
smartImpServ.setMatchedFCODefaultImportAction("Dev_ODI_Project", 1);
It can only define the default action for a First Class Object i.e. for all the objects of a specific type. For instance you can set the default actions for any project as CREATE/COPY (equivalent to 1 as you used in your code):
smartImpServ.setMatchedFCODefaultImportAction(ISmartImportService.PROJECT_OBJECT_NAME, ISmartImportService.SMART_IMPORT_ACTION_CREATE_COPY);
The values you can use as the pFCOObjType parameters are all the Fields ending by _OBJECT_NAME in the ISmartImportService interface.
If you want to specify the action for a specific object, you would need to use a response file from a previous import with the importFromXml method.
I have this string 'custom_controller'.
I need to get it to this 'CustomController'.
It's from the required file name and the class name inside is needed.
To cut to the chase, the code is here.
It is a project that comes from the Rack tutorials on Github. rack/rack/wiki/Tutorials
But rather than just name them custom.rb and class Custom, I want it more like a Rails app without requiring Rails or any of the gems that come with Rails except maybe Rack.
This is not a Rails app. This is not even a Sinatra or Padrino app. It's just a home brew web framework using Rack.
You can use plain ruby to build your own camelize method.
def camelize(string)
string.split('_').map(&:capitalize).join
end
This would also work:
"custom_controller".gsub(/_*([a-z]+)/i) {$1.capitalize}
And is closer to the way Rails handles this issue. I'd suggest you look at the Rails code as it also handles some variations on the simple case you quote. For example, how would you handle name spaced controllers 'foo/custom_controller'?
The desired result is just the camel case representation of the source string. You can try to use 'custom_controller'.camelize.
You could get it as 'CustomController' by doing following :
'custom_controller'.split('_').collect{|x| x.camelize}.join
If you want to use this as class you could do following :
'custom_controller'.split('_').collect{|x| x.camelize}.join.constantize
constantize is basically used to convert any string to class.
But I am not sure whether that works for controller. You can read more about it here

How to perform a unit convertion in a nice way with CakePHP?
I have all mesurment values saved in "mm" in the database, if the user has another perfered mesurmentsystem then "metric" i need to convert and display the mesurments in that system.
Make a lib class in /Lib where you put the basic conversion stuff.
Then you either use it as Lib directly anywhere in your app (model etc) or you can extend it as a helper for your view level.
Check out how the core does it with CakeNumber and NumberHelper, CakeTime and TimeHelper and String and TextHelper.
Analogously should you code your measurement conversion.
I am writing an application that has both extjs and sencha touch version. my current folder structure is like
root
...extjs4application
......app
.........model
.........store
.........view
.........controller
...senchatouch2application
......app
.........model
.........store
.........view
.........controller
model and store are similar in both application so i need to organize my folder structure in such a way that both application could share single/common model and store folders. What could be the possible solution? Please help
Based on a cursory glance over the source for Ext.app.Application it looks like it's possible to change the paths without overriding anything.
The path to the app folder is controlled by the appFolder config which defaults to "app." You can change this as you see fit but it's not necessary to do so.
Also included in the application class is an undocumented config called paths which is an object containing simple (key, value) pairs. Example:
paths: {
"Ext": "/path/to/Ext",
"Ext.ux": "/path/to/Ext/ux"
// etc...
}
The Ext.app.Application constructor checks for the presence of the paths config and calls Ext.Loader#setPath for each entry. You can read more about Ext.Loader at Sencha Docs
I don't like including disclaimers with my answers, but in this case I feel I should: I haven't personally used this to create an application so I can't completely vouch for its correctness, but it should be a start. If this should fail, you may need to override or extend the library classes to suit your needs (probably either Ext.app.Application or Ext.Loader).
I haven't found any reason for the existence of a few of the App Engine classes. There's a PhoneNumber, a Link, a PostalAddress, a GeoPt, a Rating, etc. Why are these given special treatment? They don't seem to have any smarts - e.g. geo searching. I know Link has more space than a String property, but the rest?
See:
http://code.google.com/appengine/docs/java/datastore/dataclasses.html
Those types are 'semantic' types. They're present in the Java API for parity with the Python API. In the Python API, they define special behaviour with regards to the .to_xml() method - for example, a PhoneNumberProperty serializes like this:
<property name="foo" type="gd:phonenumber"><gd:phoneNumber>12345-678</gd:phoneNumber></property>
I think they're mostly just there to cover common cases and save developers time. If a lot of apps use a phone number field, why require each developer to have to write them? A developer can still write their own if they need/want to.
Not sure about java, but in python the following model/code (tested on dev server) will throw BadValueError, with the message "Invalid URL: stackoverflow.com"
class foo(db.model):
link = db.LinkProperty()
bar = foo()
bar.link = 'stackoverflow.com'
While:
bar.link = 'http://stackoverflow.com'
Works fine.
I haven't tested, but the other properties may or may not also do validation.
Basically using this types in your models allows to add indirect meta data to your code. This may be useful if you are working with any kind of universal renderer for your model classes or if you are performing validation of user input on your models.
For example if you are using PhoneNumber type for a field named userNumber you reflection based renderer may understand that it should automatically assign corresponding validator to text field which will represent it.

Pavel.
