Question

I have a JAX-RS 1.1 resource FooBar that has a method which accepts a String POST parameter as follows

@Path("/foobar")
public class FooBar {

  @POST
  public void doSomething(@FormParam("name") String name) {
    //...
  }
}

Is it possible to protect this from being called if name is longer than a specified maximum? I wonder what it does if the name is of size 1GB?

Answer 1

Usually, you can configure maximum size of post request on ServletContainer. For example, Tomcat has maxPostSize setting in httpConnector directive. By default it’s 2 mb or so in Tomcat.
