Try the following.

@GET
@Path("/path1")
public String getFunction(
    @QueryParam("param1") String intParam1Str
) {
    Integer intParam1 = null;
    try {
        intParam1 = Integer.parseInt(intParam1Str");
    } catch (Exception e) {
        //do whatever you want
    }
}

-1

This is because the number you are passing in:

1222534625474

is larger than the largest integer value java can handle: 2^31-1 or 2147483648.

Try setting the parameter type to long:

@GET
@Path("/path1")
public String getFunction(
    @QueryParam("param1") Long intParam1
) {
    ...
}

I do not understand your comment. – JSK NS May 19 '14 at 14:26

Then you should accept a string, and try to parse to an integer, long, etc. – JSK NS May 19 '14 at 14:38
