I am using JDE 4.7 and its default simulator. I have a few apps installed but when making a call from on app

CodeModuleGroupManager.loadAll()

it returns null. I also tried

String moduleName = ApplicationDescriptor.currentApplicationDescriptor().getModuleName();

CodeModuleGroupManager.load(moduleName);

it also returns null.

Any thoughts on what could be wrong here? Thanks

CodeModuleGroupManager.loadAll() returns null if there is if no list of groups available, or list of available groups has no members. Please confirm is there aby group there or not?

First make sure

CodeModuleGroupManager.getNumberOfGroups() method is not returning 0. if it is returning zero then there is no group avilable for the perticular application module or all application modules.

CodeModuleGroupManager.getNumberOfGroups() does return 0.

Here comes the dumb question - what is a group?  I thought every app installed is a group..

I try to follow 

http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800708/800646/How_To_...

to get a few attributes out of an app's JAD file. But so far it does not work...

No, Every app which is on device(installed) is not an group but group is a groupname for a type of applications. you can specify a group name for a app.

If you need to get info for a particular app then use CodeModuleManager class. Using this you can createNewModule(), getModuleName(), getModuleHandle(), module version, module url etc.

I want to get a few properties I created in the JAD file following the "how to" guide in knowledge base (link provided above)

here is the codes they provided:

CodeModuleGroup[] allGroups = CodeModuleGroupManager.loadAll();
CodeModuleGroup myGroup = null;
String moduleName = ApplicationDescriptor
   .currentApplicationDescriptor().getModuleName();

for (int i = 0; i < allGroups.length; i++) {
   if (allGroups[i].containsModule(moduleName)) {
      myGroup = allGroups[i];
      break;
    }
}

// Get the property
String description = myGroup.getProperty("MIDlet-Description");
String custom = myGroup.getProperty("My-Custom-JAD-Property");

So I am puzzeled what extra step I need to do in order to make it work?

Hi,

if you want to get the value of ordinary properties supported in Jad. Then Use the fowllowing code : 

 CodeModuleGroup cmg = CodeModuleGroupManager.load(group_name); 
 for( Enumeration e = cmg.getPropertyNames(); e.hasMoreElements(); ) 
 { 
     String name = (String)e.nextElement(); 
     System.out.println( "Name: " + name ); 
     System.out.println( "Value: " + cmg.getProperty(name) ); 
 }

If you have made some custom entries in jad, and you want to access them , then 

value = cmg.getProperty("custome property name");

will give you the value of custom property.

Unfortunately in my case, CodeModuleGroupManager.load(moduleName) returns null.

where moduleName is obtained via

String moduleName = ApplicationDescriptor.currentApplicationDescriptor().getModuleName();

Does this work only when one installs the app on phone over the air? Or should it work in JDE/simulator as well?

[amardeepjaiman]

CodeModuleManager.getModuleHandles() returns a list of handles for every COD file on the device. Are you testing it ondevice?

I am testing on JDE 4.7
