Java applet problem

818249

I have an applet which has three modes.It opens the wanted mode according to parameter given.The applet opens in a jquery popup on the web site.The problem is
when I opened browser and call the related mode from the menu, the applet opens well and after closing popup the applet is destroyed but when I call it again from the menu it freezes.The related logs on the java console are like below:

the applet freezes


The javascript code that I call applet is below:

$('#create_message_main').children().remove();

$('#create_message_main').append( '<applet name ="ortanaApplet" code="com.ortana.editor.Editor.class" width="512" height="400" archive="plugins/create_message/ortana_applet.jar">'+
'<PARAM NAME=par0 VALUE='+create_message_parameter+'>'+
'<PARAM NAME="cache_option" VALUE="Yes"> '+
'</applet>');


I remove the code in the create_message_main div when mode changes then add the applet code into div again with changed parameter.If the calling type is the reasen for problem how can update applet with changing parameters.Thanks for your replies.

After my tests I realized that my applet is stuck when I call second time my applet it reads the image sources from the jar very very slow.In the first call I printed the resource path that I give with "getClass.getResource(adress)" It is like below:

In the second applet call it reads images very slowly.I think it requests the applet jar and downloads it for every image.How can I prevent tihs problem.Is there a way to get the read resources from cached applet jar on the disk.
