Re: Is there a way so I can use ProjectRun AsRun on Server functionality while using the new GWT eclipse plugin?
Thanks for your answer Jason. I was previously using cypal studio because it makes it easy for you to deploy your compiled code (HTML CSS) and java clases (Servlets) to a local server in the traditional Eclipse way. (Run As Run on Server). I've put almost all of my GWT client and server code inside a JAR, and my team use this jar to build products using this jar as their core. The team members simply make extensions to server classes, they are not involved in changes to the UI (GWT) code. The team uses WEB MODE only, because of performance reasons. My original question was, how could I deploy the war directory to a server inside eclipse? Thank you very much for your attention. joe On 17 ago, 11:09, Jason Parekh jasonpar...@gmail.com wrote: Hi jmpeace, Could you explain your use case a bit more (so in the future, we can better support it.) My understanding is you'd like to do infrequent GWT compiles and package this into a WAR and run it on a server. Is the server GWT's jetty instance or your own app server?

you could use another thread so that the operation doesn't block your

Re: Synchornous GWT, how can i do that
Please take a took to this code
I have written this code to be able to make RPC calls one after

public void onResult(boolean result, Throwable caught) {
if(result)
{
/*TWO*/CustomWaitingOperation.execute(new
CustomWaitingOperation.ResultCallback(){
public void onResult(boolean result, Throwable
caught) {
if(result)
{
}
}
});
}
}
});
CustomWitingOperation.java
public class CustomWaitingOperation {
/*Fields*/
public interface ResultCallback {
void onResult(boolean result,Throwable caught);
}
public CustomWaitingOperation(/*Parameters Here*/) {

}
public void onResponse(boolean result,Throwable caught) {

How could I compress contents of a GWT-RPC response

Re: Servlets and web.xml
Why don't you try opening a separated browser window and point to
http://localhost:/FileServlet
It should give you a HTTP Status 500 error meaning it is listening
there in hosted mode

Hi,
Thanks again for the help.
GWT.getModuleBaseURL() returnshttp://localhost:8080/com.tergwt.Main/
so i guess the path is correct...
I tried to put the hardcoded path to my app folder (/home/jon/
GWTDeploy/webapps/com.tergwt.Main + /FileServlet) and i still get this
404.
I even tried to point it to the classes folder ...
I'm not sure to understand very well in what involves this setAction
line. It should point to my FileServlet.class file ?
Or something else ?
This servlet/form works fine in the embedded tomcat in hosted browser.
So i guess something between the two config is missing (in my jetty
server)
But i can't find what ! It's quite annoying :)
Thanks in advance...

Hey i just saw this before your message.
But even with that, it stills not working.

And i changed my formAction to form.setAction(/FileServlet); instead
of form.setAction(GWT.getModuleBaseURL() + /FileServlet);
So now, no more idea on my side ...

have to specify a valid url.
You are configuring /fileServlet to go to your servlet and then asking
requesting a url of /FileServlet.
Aren't you? I am not sure but think capitalization is significant.

Wow, i'm almost happy !
I finally managed to get rid of the HTTP ERROR 503.
I misplaced the bin files (.classes), they need to be under yourapp/

So i took the time to copy libs here too (in lib folder).
OK this done, i don't success to upload my file.
I browse it correctly, but when i click submit i get : h2HTTP ERROR:

My entrypoint if needed:

Hi to all,
I'm under linux and I follow this
tutorialhttp://jeff.ourexchange.net/2008/03/01/deploying-gwt-applications-wit
I have a simple gwt application that browses for a file and upload it
using a servlet (class FileServlet extends HttpServlet).
In hosted mode (with tomcat) with the hosted browser of gwt, all works
as expected, my servlet runs fine.
I try to deploy application to a Jetty embedded server and i get a
HTTP ERROR: 503 SERVICE_UNAVAILABLE if i enable my servlet in web.xml
(under WEB-INF). Also when i run the Jetty server (in console), i get
two exceptions like Failed startup of context
org.mortbay.jetty.webapp.webappcont...@1b9ce4b{/com.tergwt.Main,file:/
home/jon/GWTDeploy/webapps/com.tergwt.Main/}
java.lang.NullPointerException
I don't see the form of the upload.
If i disable the servlet declaration in the xml file, the server runs
without exceptions but it doesnt upload and i get h2HTTP ERROR:
404/h2preNOT_FOUND/prepRequestURI=/com.tergwt.Main//
FileServlet/p if i try...
So i guess it has something to do with the web.xml file.
Unfortunately, i don't success with it.
Here is the content of my web.xml file without the web-app marks.
servlet

servlet-classcom.tergwt.server.FileServlet/servlet-class
/servlet
servlet-mapping
servlet-namefileServlet/servlet-name
url-pattern/files/*/url-pattern
/servlet-mapping
I don't know what else i can do to fix this problem as i'm not an
expert with these things.
My main.java contains the upload form and it uses the FileServlet to
make the doPost().
Here is the full tree of my webapp deployed folder with the embed
Jetty server :http://filebin.ca/cjgvj/tree.txt.

Class.forName(String) Instance
I was wondering if someone could help me out with this problem. I need to get and object from an especific class (that extends a class named DDOField). I'm doing this to get a new instance according to the type requested: HashMapString, DDOField availableFields = new HashMapString, DDOField(); availableFields.put(simpletext, new SimpleTextField()); availableFields.put(password, new PasswordField()); availableFields.put(validated, new ValidatedField()); availableFields.put(richtext, new RichTextField()); availableFields.put(textarea, new TextAreaField()); availableFields.put(simpledate, new SimpleDateField()); availableFields.put(short, new ShortField()); availableFields.put(int, new IntField()); availableFields.put(long, new LongField()); availableFields.put(enum, new EnumField()); availableFields.put(boolean, new BooleanField()); type = simpletext; DDOField field = availableFields.get(type); That way I get the variable 'field' to point to a new instance of the type 'simpletext' (new SimpleTextField()). The problem is that I'm creating 11 new instances just to use one of them. I've tried to use Class.forName but it is not supported in GWT, also tried GWT.Create() but it didn't work as I expected or maybe I'm doing something wrong.
