I’m reposting this here. Hopefully I’ll get better exposure:

I’m trying out the Mobile Module in trial mode and am trying to connect. When I do using this:

[iowaeng2:8088/main/system/mobile?project=Kanban](http://iowaeng2:8088/main/system/mobile?project=Kanban)

I get: Error during session creation  
Error (error): 500 Internal Server Error

and a Restart button which then gives the same error. This happens whether I connect from a mobile device (Android) or a PC web browser. I get the same error regardless of the project name (existing or not).

I think I have the Mobile settings correct. I’m using JRE 6 and the path specifed as:

C:\Program Files\Java\jre6\jre\bin\java.exe

Any idea what I’m doing wrong?

Are you sure the path is correct? I believe the jre\bin\java.exe path is for JDK installs, and bin\java.exe for JRE installs. The path should look like one of these:

```auto
C:\Program Files\Java\jre6\bin\java.exe
```

```auto
C:\Program Files\Java\jdk1.6.0_xx\jre\bin\java.exe
```

You’re right about the path. I corrected it to :

C:\Program Files\Java\jre6\bin\java.exe

(and confirmed that it was correct) 😊

I get the same error though.

Please check your gateway logs for error details.

Which log am I supposed to be looking in. wrapper.log doesn’t appear to have anything relevant.

Try setting the loggers “Mobile.DataServlet” and “Mobile.VMManager” to debug, and then starting a session. Then look in the logs.
