DataFile Compile Templates fails on Windows vMango 3.3.4

[Gordoe]

I am trying to Compile Templates on a Windows 7 machine and the output is <null> for CSV, Excel, XML and Binary.
Trying with javac the error is on import com.infiniteautomation.datafilesource....

Any suggestions?

Hi Gordoe,

Can you post a screenshot of where you are seeing that <null> ? Is there any error in the Mango/logs/ma.log file?

You could try updating to 3.4, but that doesn't sound like the issue.

@phildunlap!

Nothing in the ma.log

Hmm. Updating may relieve that. It's odd to me there would be an error for the Binary example importer. Perhaps you are running on a JRE instead of a JDK? That message indicates there was probably a null pointer exception in the compile method in the DWR. I see this if I run on a JRE instead of a JDK, but it may be possible another way, too.

I will release 3.4.1 of the data file module today with a better error message for this condition (not having a compiler because it's a JRE instead of a JDK)

I've upgraded to 3.4.1 and have put JAVA_HOME= variable in /overide/env.properties but the compile still fails. Compiler not found. Are you running on a JRE?

Any other suggestions? Is it possible to manually compile it?

Still, nothing in the ma.log that relates to this.

JAVA_HOME would be defined as an environment variable in the OS, so that's Control Panel --> System --> Advanced System Settings --> Environment Variables as C:\path\to\jdk1.8.0_x

You could also modify your Path environment variable to ensure jdk/bin/ is sooner on the path than jre/bin/ (or remove the jre path entry entirely)

Are you sure you downloaded a JDK when you installed Java?
