java heap space problem using JNLP

Hey all,
I have a little experience working with JNLP so i am having some trouble regarding the heap space problem. My application needs to have a suitable amount of heap space available so what i did was to change the heap size in the jnlp like this:

Now, when i run the app,it gives me these strange lines in the java console when applet call is made :

handleLaunchJVM(): RemoteJVMLauncher.setCallBack for 11
handleLaunchJVM(): now unregisterApplet 11

and opens up a new java console. And then in that console, the applet runs. ( See attachment P1 for more info)

Now, after the applet runs it gives me this beautiful message:

Exception in thread "Thread-17" java.lang.OutOfMemoryError: Java heap space
at com.AppletTakesParams.access$0(
at com.AppletTakesParams$

(See attachment P2 for more info)

What am i doing wrong with the JNLP? Can someone please help me.
Also i am using the java version 7 update 45.

Please.any help would be appreciated.
