asynchronous call back for client side method
Hi All, I am aware of remote procedure call (RPC) and using asynchronous call back in that. My question : is it possible to use asynchronous call back for client side method. for ex: client method 1 calls another client method 2, once call returns to client method 1 asynchronous call back should be invoked. the use case is same as RPC call, instead of calling method server side another client method should be called. any help would be appreciated.

Hi All,
I have a servlet "DBLookUpImpl" which implments RemoteServiceServlet. at
present I am using this servlet for RPC calls.
can I override the doGet() in DBLookUpImpl servlet and invoke the servlet
from browser using the url mentioned in url-pattern in web.xml ?
when i tried this way i am getting below error but i have put one
system.out.println statement which gets printed in tomcat console.
*HTTP ERROR: 405*
*HTTP method GET is not supported by this URL*
*code snippet of "DBLookUpImpl"*
public class DBLookUpImpl extends RemoteServiceServlet implements
DBLookUpService{
public String getLocaleString(String str) { // RPC method every thing works
fine
return some string;
}
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
System.out.println("insdie DBLookUpImpl class"); // this message gets
printed in tomcat console, i dont see any html being displayed instead i
see HTTP ERROR: 405
PrintWriter out = resp.getWriter();
out.print("");
out.print("");
out.print("welcome user");
out.print("");
out.print("");
*code snippet of web.xml*

can we use JSTL tags in gwt application
Hi we have our own framework to implement localization in J2EE application, the framework has simple jdbc call, servlet and JSTL(fmt) tag. is it possible to use same frame work in gwt application also. i didnt have problem in invoking servlet which intenally calls JBDC class, but i am facing problem in implement in JSTL tag. i got few information about changing the host page to implement JSTL tag but localization in gwt application involves chaning key words in dynamically generated html files (generated during gwt compilation).
