Weasis woes

[Dr Lawrence Fox]

I have a new dcm4chee-mysql install, and everything (except Weasis) appears to be working OK.
I have changed the AET in JMX-console and in the weasis-pacs-connector.properties file, but I have done this with other installs and Weasis works on them
I am able to import images and view them with the magnifier icon tool, but when I press the eye icon tool and try to open or save the jnlp file and then attempt to open it, it errors out like this:
Java7 starts to run, as expected.
A box comes up with "Downloading application", as expected.
Then, instead of bringing up weasis I get an Application error: Unable to launch the application. Name: Weasis, Publisher Weasis Team, Location http://localhost:8080
Details: More information: Error: Unexpected exception: java.lang.NullPointerException

I am running the latest Firefox and the latest 32-bit JDK on a 64-bit Windows 2008 Server, just as I am on my other 2 successful instances.
Can you offer me any help? Is there other information/files you need me to post?

Thanks, Larry

I am having identical problems; weasis is installed in a Ubuntu linux VM, I'm accessing studies on a Mac running OSX 10.9, Java is up to date on the Mac. Everything appears to work fine and the Weasis app is downloaded, but I get the same error message and it will not run. 

[nicolas...@gmail.com]

The two first arguments (tag) contain a return character at the end of the line. This character is passed in the main arguments. It must be removed.

I guess it is because you have edit the jnlp template.

[Rob McLear]

You are correct! I copied and pasted the text from the template file, and did not notice the return character. It works for me know.

Dr Roduit, you are a genius! Editing the template solved the problem. Thanks very much!
Just a quick follow-up: is there a way to speed up the process of "downloading" the weasis application? Is it really being downloaded? If so, can it be stored locally and pointed to?

This is already the case, the application is stored locally and updated when the plugin versions change. You should notice a difference at the fist run and then after.

Hi good Morning.

I have the same problem, They could help me solve.

thank you so much!!

[Nicolas Roduit]

If it is the same problem, you should have the response above. Otherwise, please open a new topic and describe your problem and the context (which versions of weasis-pacs-connector, which system...).
