Problems in creating test script in ALM using OTA and JACOB
===

I have created a piece of code in vbscript through which I am able to create test scripts in ALM via OTA.
Now I am trying to do the same thing through Java using JACOB as the Java 2 Com bridge and I have been able to create an empty test script using this, but I am not sure how to set the various field values.

VBScript Code (That works perfectly):

               Set tdc = CreateObject("TDAPIOLE80.TDConnection")
               If (tdc Is Nothing) Then
                 MSGBOX "Connection is not created"
               Else
                MSGBOX "Connection is created"
               End If
               tdc.InitConnectionEx connectionString
               tdc.Login userName, password
               tdc.Connect domain, project
               Set TreeMgr = tdc.TreeManager
               Set testFolder = TreeMgr.NodeByPath(uploadDirectoryPath)
               Set testFactory = testFolder.TestFactory
               Set testItem = testFactory.AddItem (NULL)
               testItem.Field("TS_DESCRIPTION")="Test script description"
               ...


Java code (Only that much that works)

         ActiveXComponent almConnection=new ActiveXComponent("TDAPIOLE80.TDConnection");
		Dispatch.call(almConnection, "InitConnectionEx", "conn string");		
		Dispatch.call(almConnection, "login", "uname","pword");
		Dispatch.call(almConnection, "connect","project","domain");		
		Dispatch treeMgr=Dispatch.get(almConnection, "TreeManager").toDispatch();
		Dispatch testFolder=Dispatch.call(treeMgr,"NodeByPath", "project path").toDispatch();
		Dispatch testFactory=Dispatch.get(testFolder, "TestFactory").toDispatch();				
		Dispatch testItem=Dispatch.call(testFactory,"AddItem","TO_BE_DELETED_SCRIPT9").toDispatch();


Now the issue is the last line in the VBScript code, 
      
                testItem.Field("TS_DESCRIPTION")="Test script description"

How do I code this in Java using JACOB?
Please help. I have done a lot of google searching, but haven't found anything substantial.
