Hello Team,

https://rsjazz.wordpress.com/2012/10/29/using-work-item-queris-for-automation/While executing the following code, I am getting execption for ITeamRepository teamRepository public static IQueryDescriptor findSharedQuery( IProjectArea projectArea, List sharingTargets, String queryName, IProgressMonitor monitor) throws TeamRepositoryException { // Get the required client libraries ITeamRepository teamRepository = (ITeamRepository)projectArea.getOrigin(); IWorkItemClient workItemClient = (IWorkItemClient) teamRepository.getClientLibrary(IWorkItemClient.class); IQueryClient queryClient = workItemClient.getQueryClient(); IQueryDescriptor queryToRun = null; List queries = queryClient.findSharedQueries(projectArea.getProjectArea(), sharingTargets, QueryTypes.WORK_ITEM_QUERY, IQueryDescriptor.FULL_PROFILE, monitor); // Find a query with a matching name for (Iterator iterator = queries.iterator(); iterator.hasNext();) { IQueryDescriptor iQueryDescriptor = (IQueryDescriptor) iterator.next(); if (iQueryDescriptor.getName().equals(queryName)) { queryToRun = iQueryDescriptor; break; } } return queryToRun; }Please help me. |

Without context, about what an exception and what is around and passed, no one will be able to help.
Maybe see https://rsjazz.wordpress.com/2013/03/20/understanding-and-using-the-rtc-java-client-api/ and set your system up for debugging? E.g. find out some classes are null or something like that? Comments Hello Ralph,
If we use the code ITeamRepository teamRepository = (ITeamRepository)workItem.getOrigin();
We are getting the value of as "null" of teamRepository.
If we use the code ITeamRepository teamRepository = TeamPlatform.getTeamRepositoryService().getTeamRepository(repositoryURI());
We are getting the exception " java.lang.NoClassDefFoundError: com.ibm.team.repository.transport.client.IInternalRawRestServiceClient".
Please help on this.

Usually, you don't need to get the ITeamRepository from the work item, because you should already be logged in.
The second method is more like it, however, for it to be able to run, it needs the Plain Java Client libraries to be in the classpath, either by creating a user library as described in Understanding and Using the RTC Java Client API section Setting Up Your Workspace for Plain Java Development, or by providing it in the classpath as described in Understanding and Using the RTC Java Client API in the section Run From Command Line. A valid base program that should do the login looks like below. /******************************************************************************* * Licensed Materials - Property of IBM * (c) Copyright IBM Corporation 2008.

I have used the below code to get IWorkItemClient object and IQueryClient object from teamRepository. However I am getting as null for both the objects.
ITeamRepository teamRepository = TeamPlatform.getTeamRepositoryService().getTeamRepository(repositoryURI());
IWorkItemClient workItemClient = (IWorkItemClient) teamRepository.getClientLibrary(IWorkItemClient.class);
IQueryClient queryClient = (IQueryClient) teamRepository.getClientLibrary(IQueryClient.class);
Note: The java class is implementing IOperationAdvisor.
Please help on this.
