Hi

I am getting the following message sent to some clients when trying to start via web start. My issue is I am not sure if this is an unsigned jar or similar or a problem directly related to the upgrade to 5.1.4. Any ideas where I look to fix this would be gratefully received

Gordon

Gordon,

this is not the error but the plain jnlp file,.  
the error is another tab… (wrapped expection or something)

Hi

Thanks - I have tracked the problem down to the plugin signature issue and am in the process or working with the provider to come up with a fix

Cheers

there are a view with: version=“-1” as version number  
if you see that then there is something wrong with it, most likely the plugins jnlp is not valid and has some errors.
