Java Web Service Client

[Rob]

I have a java web service running on my local machine so I can send messages to it from the MultiTech device. I created a Java Web Service Client, but it fails to connect to the web service from the MultiTech device.

I’m receiving the following error when creating an instance of javax.xml.ws.Service:

I’m thinking this is an issue with jamVM since I was able to test my call from my development machine without a problem. Do you know of a work around for this issue? Is there another Java VM I can use on the MultiTech device?

Thanks,

Rob

JamVM is the only Java VM that Multi-Tech has tried and tested. It might be possible to use the Cacao VM.

More information is here (some of it old):

Thanks Gilles,

I have tried the Cacao VM, but had the same issue. I was able to solve the problem by using OpenJDK-6 and Cacao VM together. You can see the OpenJDK-6 thread in this forum for more detail.
