mmazure2 Oct 21, 2003 4:44 AM (in response to mmazure2)Now I'm a little bit closer. Now I get the following exception when running an applet on the html page:
java.lang.ExceptionInInitializerError

I guess that's still problem of configuration.... Please help! -

mmazure2 Oct 21, 2003 4:52 AM (in response to mmazure2)hmmm, and I guess important is that this exception is raising in this line:
topicConnection = topicConnectionFactory.createTopicConnection();

stephanenicoll Oct 23, 2003 12:50 AM (in response to mmazure2)The first one was a security issue. You are not allowed to open TCP/IP sockets on any host but the one where the applet was downloaded.
I assume you solved the issue
The other one is a Class.forName which failed. Are you sure your applet have all the classes needed (check client jars)
Does your applet work fine with the AppletViewer?

mmazure2 Oct 23, 2003 3:50 AM (in response to mmazure2)Yes, I was very surprised that it works fine in Appletviewer, is it something with misiing jars?

stephanenicoll Oct 23, 2003 4:06 AM (in response to mmazure2)You shouldn't be surprised. Doing what you are trying to achieve in an applet is not that easy. My first guess is a corrupted/missing jar.
In any case, it's related to your configuration/deployment. It has nothing to do with JBoss nor JMS in general.

mmazure2 Oct 23, 2003 4:08 AM (in response to mmazure2)Sorry, I tried another time with appletviewer, and it doesn't work. I've got the same exception when using
>>appletviewer http://80.55.35.62/gazex/urzadzenia.html

7. Re: Applet & JNDI
stephanenicoll Oct 23, 2003 4:10 AM (in response to mmazure2)Is your JBoss running on 80.55.35.62 ?

8. Re: Applet & JNDI
mmazure2 Oct 23, 2003 4:12 AM (in response to mmazure2)Yes, I have two network adapters, but my main IP is 80.55.35.62. My JBoss is running on that IP.

stephanenicoll Oct 23, 2003 4:13 AM (in response to mmazure2)DAMNIT! please provide the full stracktrace when you have a problem...
If you check the cause, it's a security exception being thrown by the applet (meaning the applet has not the right to read some JBoss property or something)
You will have to sign your applet and give it the needed rights.

abhijit_deb Oct 28, 2003 3:44 PM (in response to mmazure2)Could you solve this problem at all! I am having the same problem and it looks like not a problem of missing jar or some thing.
Thanks in advance,

14. Re: Applet & JNDI
sulfur Nov 24, 2003 12:14 PM (in response to mmazure2)People, this is basic applet behaviour. It is restricted by the sandbox security.
Look at the root cause of your exception. It is trying to do a getProperty() which it doesn't have permission to. It has nothing to do with missing jars!
To make it work, either:
1) Modify the java.policy file on your client to grand permission, or
2) Sign the damn JAR file :P
