Some times when we try to fetch very large results from a database, it may take hell lot of time. But within that time, our server will get timed out and show you a timeout error. Argh, annoying. Isn’t it?  This may even happen when we are involved in an important task which may take hours to complete. Usually, the wildfly server may get a timeout by 300 seconds (5 minutes). We can change this timeout problem by just adding a small piece of code in the standalone.xml file which will be available in \wildfly-8.0.0.Final\standalone\configuration.  Below, I have  provided the code change which is required to alter the timeout. First, open standalone.xml, and search for

<subsystem xmlns="urn:jboss:domain:transactions:2.0">

default code will be like

In the code given above you can change timeout as per your need. All you have to do is just add one more line of code in the subsystem.

So that the edited piece of configuration file will look like the below one:

If we are adding the above code, hooray!!! The time out is changed. Hope this helped you.
