org.jboss.resteasy.spi.UnhandledException: java.lang.NullPointerException
Hi,
I am creating a maven resteasy web service project integrated spring. My project name is filterservice. It is having two methods in service, which is responsible
to give me data from mysql database in json and xml format. Now the problem is sometimes same code is running well but sometimes same code is giving null
pointer exception. I am not able to understand, when i am not doing any changes in my code why it is sometimes running and giving expected output and sometimes
giving errors. Error in logs are:
Servlet.service() for servlet [Resteasy] in context with path [/resteasy] threw exception
