I am using java 5. I have a prolem with access to web service by java

fine, but when i try to launch applet in my browser as a part of

finish. I am trying to access web service in init method, when i
comment this part of method everything works fine.
I am using sun AS 9.1, and web service has been tested.
Maybe someone has similar problems. I can also post sources if there
is need.

Look in the Java console for your browser to see if there are any
errors/exceptions reported. The applet is most likely failing to start.

like i have written this is the problem, you are right it is thrown by
init method in applet:

any ideas how to make it work, and what exactly is wrong?

No, because I have no idea what gra.CardWSService is, or what it does.
You are throwing a AccessControlException. Presumably because your applet is
trying to access resources which it is not allowed to access. Your applet can
only access resources directly from the host from which the class loader
obtained the code, via something like this.getCodeBase().getHost().
Even if the resources are being accessed from the same physical machine you have
to use the same "host", i.e you can't download the applet via the loopback
address (127.0.0.1) and then access resources via the ethernet interface IP (or
vice versa), or via different IP addresses for multi-homed hosts.
