No valid license found running from Eclipse

[billand...@gmail.com]

 

I am attempting to upgrade from JExplorer 2.3 to 2.7 and having a license problem. When I build and run the application as a Java Web Start, everything works fine. When I try to run it from within Eclipse, I get the following error:

JNIWrapper license check failed: No valid license found.

 I assume that this is because the jniwrap.dll moved into the JExplorer-2.7.jar. I can't figure out where to put the license files so it can be found when running from Eclipse. For the WebStart, it is in the META-INF folder and it works fine.

I took the demo and made it an Eclipse project and get the same problem. Here is the stack trace:

Hello Bill,

It seems like you run your application in an environment that is not supported by your JExplorer license. JExplorer 2.3 doesn't support 64-bit environments and I suppose that your license doesn't support 64-bit environments too. To make sure that the reason is in the license, please try to run your application with JExplorer 2.7 using JRE 32-bit. If you could run your application, then the reason is in license. In this case you will need to send requests to our Sales team at sa...@teamdev.com and request and updated JExplorer license that supports 64-bit environments.

Sincerely,
Vladimir Ikryanov

Vladimir -

 

I have checked and it is running a 32 bit JVM. We have other external DLLs with our application that don't support 64 bit JVM so I was pretty sure that I was. In fact, I have uninstalled all 64 bit JVMs since I did once have a problem where it was picking up the wrong one.

 

Is there a way to specify from the command line where the license files are?

 

Thanks

 

Bill

Vladimir -

 

I have figured it out.

 

 I made a META-INF folder in the /bin folder and put the licenses in there and it worked.

 

Thanks,

 

Bill
