Online Webservice: java.lang.OutOfMemoryError: Java heap space

[tfazionato]

Hi,

Informing an xsd in the online service, I am getting the following message: java.lang.OutOfMemoryError: Java heap space.

You could increase the memory of the online service?

Grateful.

Hi, I don't think so because is free heroku paas but is easy to run
locally. Just check the readme.
Cheers

I encountered the same http500 as above so I followed the excellent instructions in the readme on running it locally. All builds and all artifacts appear to have succeeded. But when I run xsd-forms-generator-webapp, it runs fine till I hit Generate, and then I get a different error:
