I work with a signed midlet, which makes a http connection. From what I've read http connection doesn't require signing with a certificate in a Blackberry. So I assume the security is not the problem.

I am testing on Blackberry device simulator 4.2.2 and MDS services simulator. I can load the COD file for the midlet and it appears on the screen. The log on screen opens,but when I press log on to connect I get "jvm error 104 uncaught runtime exception". What can be the cause for this and how can I avoid it?

Apparently there is something wrong with your code, though it is syntactically correct (otherwise it would'nt be compiling). For greater details on where the error is, you would have to post your code.

Try it with debugging.
The BB IDE comes with a debugger witch can be started with JDWP, if your are using third party development tools (e.g. eclipse).
There you have the possibility to read the System.out.println()s which are redirected to that console.

So you mean I have to test the Blackberry project in for instance Netbeans? Debug it from there so the BB IDE starts?

So far I have tested with Blackberry device simulator 4.2.2 and MDS services simulator. Isn't there any way to read the System.out.println()s from there?

You can use whatever IDE you like, also the one provided by RIM. Which is the easiest to start because you have not to configure much. But it is also the least comfortable and productiv to work with.

You can also test, if your MDS is running correctly by browsing the web with your blackberry device simulator. This should work fine, if MDS is running correctly.

If you are using the RIM IDE you see your System.out.println()s at the bottom of the IDE, between all the other stuff outputet from the debugger.
