How to fetch already created sessions from Informatica Repository (Informatica SDK)

Question

Hi guys,I'm using the Informatica SDK to create a java application that accesses the Informatica repository. I'm having a bit of an issue while trying to fetch the names of already created sessions from the Informatica Repository. I'm able to connect to the repo without any issues and have been able to add sources, targets, mappings, sessions, workflows, etc... and save them directly afterwards. However, when I try to fetch the session names from a folder in the repository, I get the following error:Mon Jul 27 15:03:01 PDT 2015 Severity:DEBUG ThreadID:14 Running the pmrep process in the working directory: [C:\Informatica\9.6.1\clients\PowerCenterClient\client\bin].Mon Jul 27 15:03:01 PDT 2015 Severity:DEBUG ThreadID:14 Running the command [listobjects -o session -f "TechOps" -s . ].

Here's my code for fetching:// Create a list of session names and store the names
List<String> sessionNames = null;
try {
    sessionNames = folder.fetchSessionNamesFromRepository();
} catch (RepoOperationException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (MapFwkReaderException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
// Print the list of session names
for (int i = 0; i < sessionNames.size(); i++) {
    System.out.println("Session " + i + " is " + sessionNames.get(i));
}I've confirmed that the folder object works fine as I can add and save other objects to that folder in the repo.The other odd thing is that if I go to the install path for Informatica on my machine and I run pmrep from the command prompt followed by the command to fetch session names, it works fine.Any help on this would be greatly appreciated.Thanks

Hi neel007,
Just use a List instead of a Vector, it's more performant :
List<Folder> rep_FetchedFolders = new ArrayList<Folder>();If you need to synchronize your list, then
List<Folder> rep_FetchedFolders = Collections.synchronizedList(new ArrayList<Folder>());Also, if you're using Java 5 or higher and if you're sure listOfTargets contains only Target objects, instead of this
for(int b=0; b<listOfTargets.size();b++){
   Target trg = ((Target)listOfTargets.get(b));
   t_folder.addTarget(trg);
}you may do this :
for (Target trg : listOfTargets) {
   t_folder.addTarget(trg);
