[tm-dev] Programatic Creation of Filters/Pools/References

[Daniel Johnson <danijoh2@xxxxxxxxx>]

Hi,

I am trying to programmatically create Filter entries on a server, and it seems to work fine, but as soon as I exit Eclipse and re-launch it seems that all of the Filters on that Server are corrupt, with a NPE being thrown in the error log.

Can anyone help explain how to do this and/or what I am doing wrong?

Here is my code:

String hostName = ... // Get host name

String username = ... // Get username

// Create MyProfile

ISystemRegistry systemRegistry = RSECorePlugin.getTheSystemRegistry();

ISystemProfile myProfile = systemRegistry.getSystemProfile("MyProfile");    

if (myProfile == null) {

  myProfile = systemRegistry.createSystemProfile("MyProfile", true);  

}

// Create the host

IHost host = systemRegistry.getHost(myProfile, hostName);

if (host == null) {

  // Create with SSH to add the SFTP subsystem

  host = systemRegistry.createHost(myProfile.getName(), systemRegistry.getSystemTypeById(IRSESystemType.SYSTEMTYPE_SSH_ONLY_ID), hostName, hostName, "MyProfile Description");

  host.setDefaultUserId(username);

}

for (ISubSystem subSystem : host.getSubSystems()) {

  // Want the SFTP subsystem

  if (subSystem.getName().equals("Sftp Files")) {

    ISubSystemConfiguration config = subSystem.getSubSystemConfiguration();

    // Get the Pool Manager for my profile type

    ISystemFilterPoolManager poolManager = config.getFilterPoolManager(myProfile);

    // Create the new filter Pool for my new filter (returns null if it already exists)
    ISystemFilterPool pool = poolManager.createSystemFilterPool(server.getName()+":ssh.files", true);

    if (pool != null) {

      // Create my new filter, this is a brand new Pool so don't worry checking if it already exists

      pool.createSystemFilter("MyFilter", new String[] {"/path/of/super/secret/resource/"});

      // Add a reference from the SFTP subsystem to my new pool

      subSystem.getFilterPoolReferenceManager().addReferenceToSystemFilterPool(pool);

    }

  }

}  

And here is the NPE after restarting Eclipse:

java.lang.NullPointerException
