 Hi all,
 I am using the SCM commands in my Java Program for Login to repository, fetching streams for eg  
code for Login to repository 
String Logincommand="cmd /c D:/RTC502DEV/IBM/TeamConcert/jazz/scmtools/eclipse/lscm login -r "+repositoryURI+ " -u " +userId+ " -P " +password;
Process pro=Runtime.getRuntime().exec(Logincommand);
BufferedReader r = new BufferedReader(new InputStreamReader(pro.getInputStream()));
String line;
while (true) {
       line = r.readLine();
       if (line == null) {break; }
From above eg. we can Login to repository. from same Logic we can also get the List of Streams of specific project.
Now I want to fetch the ichangeset Handle details like UUID ,Item Id ,state id etc. by using SCM commands. in java program . Is it  Possible to get that details using scm commands.

The LSCM command is designed to be called using a shell or command window. My assumption is, that you will have to do that and parse the data that is returned in the standard out. There might be a way to call LSCM directly from the libraries, but I have never attempted to do that and don't have specific suggestions at the moment. I would likely try to find the main method that is called from looking at the libraries in Eclipse and try where that leads me.

The Java API can be used to access such data. See and the related posts.
You can cal LSCM or the SCM commandline as a process and then you can parse the text output see the LSCM reference.
