Need help adding an Annotated field.

[b_mjoshi78]

Hi,

I am trying to utilize Javassist to add an annotated field to my class. The snippet of what I am trying to accomplish is listed below.

//I am trying to add the line below as a new field.

@Context HttpServletRequest request;

@POST
@Path("restMethod")
public String testMethod()
{
    //request should be injected with information needed by

    //the container at this point.

    String remoteAddr = request.getRemoteAddr();
    return remoteAddr;
}

Basically I am trying to get an existing function that uses JSR 311 Jersey and add a new @Context field

so that the container will inject HttpServletRequest, which I can use by instrumenting the testMethod function.

Thanks in advance for your help.

Sincerely,

Bharat Joshi

The tutorals [http://www.csg.is.titech.ac.jp/~chiba/javassist/tutorial/tutorial2.html] and the javadocs [http://www.csg.is.titech.ac.jp/~chiba/javassist/html/]
would be a good place to start

Hello Jaikiran,

Thank you for your response. I looked into the links sent, but I don't think that they were addressing the scenario that I was looking for. I am looking to insert a statement to accomplish Dependency Injection of a field. What I saw was information on how to create new annotations, but I don't think I saw anything that might help me accomplish DI. Thanks for your help, and please let me know if you might have any other suggestions I can investigate for this.

Thanks,

Bharat
