Question

i am using Netbeans to create a Web Service and the code is written in java. My problems arises from creating 2 functions that will be accessible by a client. The functions look alike by name but their parameters are different.

When building the web service(int a war file) i get no complaints. However when deploying the war file onto a glassfish server renders errors that would make me conclude that glassfish somehow is getting confused about 2 functions of the same name without looking into the parameter list. Is this a common occurrence and is there a workaround?

For example:

@WebMethod()
public Long startMission(@WebParam(name=”session”) Session session, String name{
…..
}

@WebMethod()
public Long startMission(@WebParam(name=”session”) Session session, Long num{
…..
}

The error on the glassfish server comes back to me and tells me that the 2nd StartMission function does not contain an entry point for parameter @Long num – which tells me that it does not recognize 2 functions of the same name. Perhaps i am thinking about this the wrong way. Any help, options, suggestions would be appreciated. thanks!

Answer 1

You can distinguish between the two methods by specifying the operation that they correspond to. This is done by specifying the operationName member value for the WebMethod annotation.

For example,

@WebMethod(operationName='startMissionWithName') public Long startMission(@WebParam(name="session") Session session, String name{ ..... }

@WebMethod(operationName='startMissionWithId') public Long startMission(@WebParam(name="session") Session session, Long num{ ..... }
