I have a web application that has a rest method in it that accepts a POST request and

request.getParametersMap() call in order to get all the passed form parameters. In a
normal servlet, this should return all of the form parameters to my application in a Map,
but I'm seeing strange results when running this under Weblogic versus Tomcat. In
Weblogic, it behaves correctly, meaning I am able to see all of the parameters in the
Map, whereas in Tomcat I consistently get 0 parameters back. Something is very fishy, but
maybe it has to do with differences in the servlet api implmenetation and how CXF works
with this. One thing I did notice is that when I explicitly put in a
@FormParam("username") in the method signature, it is then able to parse out
the username and it populates the method argument properly that way, but I'm still unable
to access that same parameter via request.getParameter(). Has anyone ever seen this
behavior?
I am using CXF 2.2.10.
My REST method without explicit @FormParam mappings looks something like this:
@POST
@Path("/user/create/{token}")
@Consumes("application/x-www-form-urlencoded")
@Produces("text/plain")
public int createUser(@PathParam("token") String token) {
...
..
.
Map<String,String> parameters = request.getParameterMap();
// this outputs zero
logger.info("Request parameters size: "+parameters.size());
}
My REST method with an explicit @FormParam looks something like this:
@POST
@Path("/user/create/{token}")
@Consumes("application/x-www-form-urlencoded")
@Produces("text/plain")
public int createUser(@PathParam("token") String token,
@FormParam("username") String username) {
...
..
.
// this outputs the value passed in the http post request correctly
logger.info("Username: "+username);
Map<String,String> parameters = request.getParameterMap();
// this is still zero
logger.info("Request parameters size: "+parameters.size());
}
I think it is to do with the difference in the way Servlet API is
implemented on different containers. When you use @FormParam, it is CXF
which deals with it but without it you do depend on how
request.getParameterMap() is implemented - CXF does not intercept this
method.
By the way, try using MultivaluedMap instead if you'd like to get all
the parameters...Also, consider migrating to newer CXF, 2.5.x is the
oldest maintained branch
