internationalization clients plugins, generate properties

Hello,

I'm working on the internationalization of plugins, which is to monitor the error messages in different languages depending on the language that you start the eclipse.
I use RTC 3.0.
For the server plugins I have no problem. Briefly detail as I do:

I have implemented a class that used by other advisors Messages.java, where I pass the properties of messages
private static final String BUNDLE_NAME = "com.ibm.team.server.process.messages";

Into the advisor, when I generate a message add the following lines:
IAdvisorInfo info= collector.createProblemInfo(getSummary(d.getName()), getDescription(state,d.getName()), ID);
info.setProblemObject(workItem.getItemHandle());
collector.addInfo(info);

These lines are what generated the error and also call getSummary and getDescription methods, I have implemented as follows
private String getSummary(String descriptor) {
return NLS.bind(Messages.getString("RequiredApprovalsAdvisor.ATTRIBUTE_NOT_SET_SUMMARY"),descriptor);
}
private String getDescription(String descriptor, String state) {
return NLS.bind(Messages.getString("RequiredApprovalsAdvisor.ATTRIBUTE_NOT_SET_DESCRIPTION"),state,descriptor);
}
in line:
Messages.getString("RequiredApprovalsAdvisor.ATTRIBUTE_NOT_SET_DESCRIPTION"),state,descriptor);
we can pass the strings you want separated by commas, in this case appears state and descriptor.
These String are then identified in the message as if they were command line parameters
RequiredApprovalsAdvisor.ATTRIBUTE_NOT_SET_SUMMARY=Para pasar al estado ''{0}'' es necesario validar la aprobacin tipo ''{1}''.

Now my problem is to make the internationalization clients plugins , and are not in the same way ...because it needs to import different packages ...
Somebody has worked or know this?any reference or example?
Would appreciate your help ...

Thank you very much
