I have this problem and I'm really going crazy without having a result.
I have a form and all fields are required through validator.xml
My form contains a field for the upload image (required)
When I click the submit button present a paggina waiting through (execAndWait configured in struts.xml).
my big problem is this:
the waiting page always redirect to my form page with text (the file field and mandatory).
Here is the code:
/register.jsp
<!-- al submit chiama l'action register -->
<action name="register" class="action.Register" method="execute" >
<interceptor-ref name="defaultStack" />
<interceptor-ref name="fileUpload">
<param name="maximumSize">10000000</param>
<param name="allowedTypes">image/jpeg,image/gif,image/jpg</param>
</interceptor-ref>
<interceptor-ref name="params"></interceptor-ref>
<interceptor-ref name="execAndWait">
</interceptor-ref>
<result name="success">index.jsp</result>
<result name="input">/register.jsp</result>
<result name="wait">/test.jsp</result>
</action>
waiting page:
<meta http-equiv="refresh" content="5;url=<s:url includeParams="all" />"/>
</head>
<body>
<p>your request is processing...</p>
<img src="images/indicator.gif"/>
my form:
<s:form method="post" action="register" validate="false" enctype="multipart/form-data">
<s:textfield key="utenteBean.nome" name="utenteBean.nome" value="a" />
<s:textfield key="utenteBean.nickname" name="utenteBean.nickname" value="a" />
<sj:datepicker key="utenteBean.nato" name="utenteBean.nato"
showButtonPanel="true" displayFormat="dd/mm/yy" value="25/09/1983"/>
<s:textfield key="utenteBean.professione" name="utenteBean.professione" value="a"/>
<s:textfield key="utenteBean.eta" name="utenteBean.eta" value="3"/>
<s:textfield key="utenteBean.dj_preferito" name="utenteBean.dj_preferito" value="a" />
<s:textfield key="utenteBean.rave_fatti" name="utenteBean.rave_fatti" value="3" />
<s:textfield key="utenteBean.sito_preferito" name="utenteBean.sito_preferito" value="a" />
<s:textfield key="utenteBean.come_siveste" name="utenteBean.come_siveste" value="a" />
<s:textarea key="utenteBean.messaggio" name="utenteBean.messaggio" value="a"/>
<s:file label="file" name="file" requiredLabel="true"" ></s:file>
really thanks for your help
I suppose that you have put wrong field name for the file tag. Can you show us your action class? Regarding to that instead of:
<s:file label="file" name="file" requiredLabel="true"" ></s:file>
try to use:
<s:file label="file" name="utenteBean.file" requiredLabel="true"" ></s:file>
or just check in your action class the name of the file property.
yes sure ... below my Action class:
public class Register extends ActionSupport implements SessionAware {
/**

private static final long serialVersionUID = 1L;
private UtenteBeanAction utenteBean;
private File file;
private String fileContentType;
private String fileFileName;
private String filesPath;
private ServletContext context;
Map<String, Object> session;
public String execute(){
if (file != null) {
File file = this.file;
// /System.out.println(file.getName());
try {
Util.saveFile(file, fileFileName);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return ERROR;
}
} else {
return ERROR;
}
return SUCCESS;
}
public void validate(){
if(this.fileFileName==null){
this.addFieldError("file", "errore");
}
}
public UtenteBeanAction getUtenteBean() {

Thank you so much for your help ...
I solved it by putting my bean in session. I could not find a better solution after many hours of work.
If other people have the same problem I can see the changes I made in my. Action

session.put("utente", utenteBean);
if (utenteBean.getFile() != null) {
File file = utenteBean.getFile();
// /System.out.println(file.getName());
try {
Util.saveFile(file, utenteBean.getFileFileName());
} catch (IOException e) {
// TODO Auto-generated catch block

return ERROR;
}
} else {
return ERROR;
}
return SUCCESS;
}
public void validate() {
if (session.get("utente") != null) {
this.utenteBean = (UtenteBeanAction) session.get("utente");
}
if (this.utenteBean.getFileFileName() == null) {
this.addFieldError("utenteBean.file", "errore");
}
}
public UtenteBeanAction getUtenteBean() {
return utenteBean;
}
public void setUtenteBean(UtenteBeanAction utenteBean) {
this.utenteBean = utenteBean;
}

public void setContext(ServletContext context) {
this.context = context;
}
#Override
public void setSession(Map<String, Object> session) {
// TODO Auto-generated method stub

}
}
I hope I can be of help.
Thanks for the support.

I am new to stackoverflow and to Java. I am trying to fetch the data from the database then display it in a JSF page.
For the table I have a model : BusesInfo.java that contains getters and setters for the attributes of the table.
then I also have BusesDao that fetches the data from DB and stores it in an array list. BusesInfoBean that links these data to the JSF page. The connection to the database is success. the JSF page contains a table that calls BusesInfobean.busesInfo in the columns i call BusesInfo.attribute

I'm trying to use #Consumed on jpa entity with camel.
this is my route :
<route id="incomingFileHandlerRoute">
<from
uri="jpa://com.menora.inbal.incomingFileHandler.Jpa.model.MessageToDB?consumer.nativeQuery=select
* from file_message where mstatus = 'TODO'&consumer.delay=5000&consumeDelete=false&consumeLockEntity=true&consumer.SkipLockedEntity=true" />
<to uri="bean:incomingFileHandler" />
</route>
and my entity:
#Entity
#Table(name = "file_message")
public class MessageToDB implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
#Id
private String uuid;
private String fileName;
private String body;
private String mstatus;
#Temporal(TemporalType.TIMESTAMP)
private Date mtimestamp;
#Consumed
public void updateMstatus() {
setMstatus(MessageStatus.DONE.name());
}
public String getUuid() {
return uuid;
}
public void setUuid(String uuid) {
this.uuid = uuid;
}
public String getFileName() {
return fileName;
}
public void setFileName(String fileName) {
this.fileName = fileName;
}
public String getBody() {
return body;
}
public void setBody(String body) {
this.body = body;
}
public String getMstatus() {
return mstatus;
}
public void setMstatus(String mstatus) {
this.mstatus = mstatus;
}
public Date getMtimestamp() {
return mtimestamp;
}
public void setMtimestamp(Date mtimestamp) {
this.mtimestamp = mtimestamp;
}
}
I do get to incomingFileHandler bean with results from db but I do not get to the Consumed method updateMstatus . The incomingFileHandler bean is getting called continuously as always there are results from db
I have a similar implementation with camel-jpa and annotations #Consumed and #PreConsumed in the entity but none of these methods is called.
I look the camel-jpa source code and found this in JpaConsumer.java:
protected DeleteHandler<Object> createPreDeleteHandler() {
// Look for #PreConsumed to allow custom callback before the Entity has been consumed
final Class<?> entityType = getEndpoint().getEntityType();
if (entityType != null) {
// Inspect the method(s) annotated with #PreConsumed
if entityType is null the entity class inst inspect the method annotated with #Consumed and #PreConsumed.
Solution: add entityType=com.xx.yy.MessageToDB to your URI to set Endpoint Entity type.
I took the sample code from How to create custom components in JavaFX 2.0 using FXML?. the code working fine in jdk7 but the checkbox and combo box values are not working in jdk8. I am not able to click the check box even and select the dropdown.
Please guide me for the same.

I didn't dig deeper but refactoring like as following should suffice. Double check for correct executions of attached and removed listeners.
public class ChoiceCell extends ListCell<ChoiceModel> {
private Node root;
private ChoiceController controller;
public ChoiceCell() {
URL location = ChoiceController.class.getResource("ChoiceView.fxml");
FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(location);
fxmlLoader.setBuilderFactory(new JavaFXBuilderFactory());
try {
root = (Node) fxmlLoader.load(location.openStream());
controller = (ChoiceController) fxmlLoader.getController();
} catch (IOException ioe) {
throw new IllegalStateException(ioe);
}
}
#Override
protected void updateItem(ChoiceModel model, boolean bln) {
super.updateItem(model, bln);
if (model != null) {
controller.setModel(model);
setGraphic(root);
} else {
setGraphic(null);
}
}
}
Hi Friends i am developing an web application which uses hibernate and struts2. i am creating photo album i successfully done that with out using hibernate but, with hibernate it is having problem while inserting to the database. the module works like this as soon as the file uploaded it will insert the FileName, Contenttype,id and it suppose to insert the Image File(byte[]) Content also but it is showing Null in table value.. my code goes like this...
#Entity
#Table(name="PHOTOALBUM")
public class User implements Serializable {
#Id
#GeneratedValue
#Column(name="PHOTO_ID")
private Long id;
#Column(name="IMAGE")
private byte[] Image;
#Column(name="CONTENT_TYPE")
private String userImageContentType;
#Column(name="PHOTO_NAME")
private String userImageFileName;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUserImageFileName() {
return userImageFileName;
}
public void setUserImageFileName(String userImageFileName) {
this.userImageFileName = userImageFileName;
}
public String getUserImageContentType() {
return userImageContentType;
}
public void setUserImageContentType(String userImageContentType) {
this.userImageContentType = userImageContentType;
}
public byte[] getImage() {
return Image;
}
public void setImage(byte[] Image) {
Image=Change(this.getUserImage());
this.Image = Image;
}
#Transient
private File userImage;
public File getUserImage() {
return userImage;
}
public void setUserImage(File userImage) {
this.userImage = userImage;
}
public byte[] Change(File userImage)
{
// userImage=this.getUserImage();
// String name=userImage.getName();
// long len=userImage.length();
byte[] bFile = new byte[(int) userImage.length()];
try {
FileInputStream fileInputStream = new FileInputStream(userImage);
fileInputStream.read(bFile);
fileInputStream.close();
}
catch(Exception e)
{
e.printStackTrace();
}
// System.out.println("The Name Of File In Pojo Class Is:="+ name);
//System.out.println("The Length Of File In Pojo Class Is:="+ len);
//System.out.println("The Content Of File In Pojo Class Is:="+ bFile);
return bFile;
}
}
and i am saving the values like this
public class UserDAOImpl implements UserDAO {
#SessionTarget
Session session;
#TransactionTarget
Transaction transaction;
/**
* Used to save or update a user.
*/
#Override
public void saveOrUpdateUser(User user) {
try {
session.saveOrUpdate(user);
} catch (Exception e) {
transaction.rollback();
e.printStackTrace();
}
}
/**
* Used to delete a user.
*/
#Override
public void deleteUser(Long userId) {
try {
User user = (User) session.get(User.class, userId);
session.delete(user);
} catch (Exception e) {
transaction.rollback();
e.printStackTrace();
}
}
/**
* Used to list all the users.
*/
#SuppressWarnings("unchecked")
#Override
public List<User> listUser() {
List<User> courses = null;
try {
courses = session.createQuery("from User").list();
} catch (Exception e) {
e.printStackTrace();
}
return courses;
}
/**
* Used to list a single user by Id.
*/
#Override
public User listUserById(Long userId) {
User user = null;
try {
user = (User) session.get(User.class, userId);
} catch (Exception e) {
e.printStackTrace();
}
return user;
}
}
the struts action mapping goes like this...
\<package name="default" extends="hibernate-default">
<action name="saveOrUpdateUser"method="saveOrUpdate"class="com.srikanth.web.UserAction">
<result name="success" type="redirect">listUser</result>
</action>
<action name="listUser" method="list" class="com.srikanth.web.UserAction">
<result name="success">/register.jsp</result>
</action>
<action name="editUser" method="edit" class="com.srikanth.web.UserAction">
<result name="success">/register.jsp</result>
</action>
<action name="deleteUser" method="delete" class="com.srikanth.web.UserAction">
<result name="success" type="redirect">listUser</result>
</action>
</package>
and my jsp goes like this
\<s:form action="saveOrUpdateUser">
<s:push value="user">
<s:hidden name="id" />
<s:file name="userImage" label="User Image" />
<s:submit />
</s:push>
</s:form>
<s:iterator value="userList" status="userStatus">
<s:property value="id" />
<s:property value="userImageFileName" />
<s:property value="userImageContentType" />
<img src='<s:property value="userImage" />' alt"" />
<s:url id="deleteURL" action="deleteUser">
<s:param name="id" value="%{id}"></s:param>
</s:url> <s:a href="%{deleteURL}">Delete</s:a>
</s:iterator>
I am trying to call the Change Method so that it convert the file to byte[] and stored it in byte[] Image variable using setter but it is not working....
So please help me with this one .....
thanks in advance
As per my understand of question the problem is only inserting file into table. Copy & paste the Change() method into com.srikanth.web.UserAction class as you are using this action for every DB transaction. use Change() method before going to insert/update in DB.
For example:
public class UserAction extends ActionSupport{
//variable to get file from jsp
private File uploadedImage;
.....
//setters & getters for uploadedImage
#Override
public String gsexecute() throws Exception {
User user = new User();
//set image value as byteArray
user.setImage(Change(uploadedImage));
//insert or update DB here
return SUCCESS;
}
public byte[] Change(File userImage)
{
// userImage=this.getUserImage();
// String name=userImage.getName();
// long len=userImage.length();
byte[] bFile = new byte[(int) userImage.length()];
try {
FileInputStream fileInputStream = new FileInputStream(userImage);
fileInputStream.read(bFile);
fileInputStream.close();
}
catch(Exception e)
{
e.printStackTrace();
}
// System.out.println("The Name Of File In Pojo Class Is:="+ name);
//System.out.println("The Length Of File In Pojo Class Is:="+ len);
//System.out.println("The Content Of File In Pojo Class Is:="+ bFile);
return bFile;
}
}
And make sure that the table column should support the byte array insert. Ex: use BLOB column type for MYSQL.
