transaction aborted error message notification change - jsf

Question

I have added unique constraints to my database table to prevent duplicate entries. I have tested it and its working fine, On my page when when I try to submit the same values I get a message saying transaction aborted which means its working fine, is there a way to change the message:
Transaction aborted
To something like:
Task already assigned to user!
If so how would I change it?
If Possible to only change the message for unique constraint violation that would be great.
I choose the values and save them with create method:
public String create() {
try {
getFacade().create(current);
JsfUtil.addSuccessMessage(ResourceBundle.getBundle("webConstants/Bundle").getString("TimeLoggingDetailCreated"));
recreateModel();
return prepareCreate();
} catch (Exception e) {
JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("webConstants/Bundle").getString("PersistenceErrorOccured"));
return null;
}
}
And display the message on the page like this:
<h:panelGroup id="messagePanel" layout="block" >
<h:messages infoClass="alert alert-success" errorClass="alert alert-danger" layout="row col-12" warnClass="alert alert-info" fatalClass="alert"/>
</h:panelGroup>

SHORT VERSION : Just remove the "e, " in your JsfUtil.addErrorMessage(...)
It seems you are using generated Code from Netbeans like me :-)
I ran into the same problem, but I found the problems source ..
in Class JSFUtil is a method addErrorMessage(...) which is called by your Exception which looks up for a localized String of your Exception (EJBException) and also found it.
The Problem - your second Parameter "String defaultMsg" is not used in this case
public static void addErrorMessage(Exception ex, String defaultMsg) {
String msg = ex.getLocalizedMessage();
System.out.println("DefaultMsg: " + defaultMsg);
System.out.println("LocalMsg: " + msg);
if (msg != null && msg.length() > 0) {
addErrorMessage(msg);
} else {
addErrorMessage(defaultMsg);
}
}
So you can rewrite that method or or just use addErrorMessage(String msg) in your try..catch-block which directly returns your own String from Bundle.properites file
public void create() {
try {
getFacade().create(current);
recreateModel();
JsfUtil.addSuccessMessage(ResourceBundle.getBundle("/Bundle").getString("StandortCreated"));
} catch (EJBException e) {
JsfUtil.addErrorMessage(ResourceBundle.getBundle("/Bundle").getString("YourOwnFromBundle"));
} catch (Exception e) {
JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured"));
}
}
