Class compatibility issue while instantiating services using RTC client api

0
Nilesh Patil (17●3●41●50) | asked Mar 08 '16, 11:47 a.m.

Hi All,

I have created UI based eclipse plugin on top of RTC client. I am trying to instantiate IProcessItemService using RTC client api. I have used below

if(!TeamPlatform.isStarted()){

TeamPlatform.startup();

System.out.println("start up platform");

}

//TeamPlatform.startup();

String repoUri = "serverUrl";

TeamRepository repository = (TeamRepository) TeamPlatform.getTeamRepositoryService().getTeamRepository(repoUri);

repository.registerLoginHandler(new MyLoginHandler());

try {

repository.login(null);

IContributor user = repository.loggedInContributor();

com.ibm.team.process.client.IProcessItemService processItemService = (com.ibm.team.process.client.IProcessItemService) repository

.getClientLibrary(com.ibm.team.process.client.IProcessItemService.class);// This is where it throws classcast exception

} catch (TeamRepositoryException e1) {

e1.printStackTrace();

}

Could you please let me know where I am doing wrong thing or missing any inputs.

The log it shows is,
