I have been creating a REST Web Service, which would intercept requests from a client and query an employee table in the MySQL database via Hibernate and return the retrieved rows to the client. The web service calls a class in another project which solely deals with interacting with the MySQL database using Hibernate. For enabling it, I'm using Maven to build the database project into a jar which I'm then placing in the WEB-INF folder of the web service. The project structures of all three projects are attached herewith.
I had bundled all the jars required by Hibernate in the Maven dependencies. As a result, when I tried to call the deployed service from the client, it threw an exception in JBoss saying:
After browsing through a lot of solutions all pointing that this is due to me bundling the Hibernate jars in the deployed war, I removed the dependencies from Maven and instead, placed the jars in the lib folder of the JBoss server to which I am deploying my application. However, now, a new exception has cropped up, and I'm pasting the entire stacktrace here.
I have extensively searched for this exception as well, and the only solution I can find is that there may be two different logging jars on the classpath, and I would have to remove one of them. I found that JBoss 5.1.0.GA uses the jboss-logging-spi.jar for its logging and it can't be removed from the lib folder in its root. I have added jboss-logging-3.1.3.GA.jar in the lib folder of the deployment server, and if I remove it, ClassNotFoundExceptions are being thrown. So I'm now in a fix. I can't remove either of them, and if I don't remove any, then this NoSuchMethodError occurs. Please help me find a solution to this.
We find this kind of rampant individuality very disturbing. But not this tiny ad:
