Hi all,

I am quite new to WildFly. I tried to deploy a war file to WildFly which works fine in my windows PC with standalone mode. I have Linux box as well where WildFly runs in domain mode and the same application deployed there. Application deployment was successful but while accessing application it throws Internal Server Error.

Below are server logs.

As far as I can see all required jars are present in war and they also deployed correctly. Please share any kind of help or suggestion to fix this.

Best regards,
