Re: How do I call a stateless session bean (EJB) from my RPC service?
Update: A full JNDI lookup is working, but why do I not get a
reference using the annotations?
If I have
SomeBean --Bean Implementation
SomeRef -- Remote Interface
SomeRefLocal -- Local Interface
then
@EJB
SomeRef ref;
should work to get the remote interface, right?

Hi Gregor,
thanks for this extensive answer. I deployed a very simple sample
application to JBoss but for any reason I cannot access myEJBfrom my

looks like:
package de.stsch.j2ee.gwt.server;
import javax.annotation.Resource;
import javax.ejb.EJB;
import javax.ejb.SessionContext;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;

import de.stsch.j2ee.gwt.client.GwtClientSrc;
public class GwtClientSrcImpl extends RemoteServiceServlet implements
GwtClientSrc {
@EJB
StSch bean;
@Resource
SessionContext ctx;
@Override
public String getName() {
StringBuffer sb = new StringBuffer();
if (ctx == null) {
sb.append(ctx is null);
} else {
sb.append(ctx is not null);
}
if (bean == null) {
sb.append(, bean is null);
} else {
sb.append(, bean is not null);
}
return sb.toString();
}
}
And it always returns that both ctx and bean is null :-(
Any idea why?

Hi Steffen,
The simplest way to do this is to add your GWT app as a module (WAR)
to your EAR. The GWT RPC servlets will then have direct access to your
session beans local interfaces (which you must define BTW).
If you cannot do this for some reason, the situation is a bit
trickier. Your standalone Java client probably uses RMI to call your
session beans? Is so, then it is calling the beans remote interfaces
and call parameters/return values are serialized over the wire. AFAIK
you cannot call the local interface of a session bean from a class
outside its EAR. You can always use JNDI to look up the remote
interfaces of your session beans from a separate GWT module's RPC
servlets (which mimics what happens with the Java client) but this
involves your app server serializing and deserializing all objects
passed betweeen the GWT app and the enterprise app, i.e. the app
server will be serializing to itself, which is a serious performance
drain you will want to avoid.
BTW I think the reason why this is so is that each EAR or WAR deployed
on your app server is allocated it's own classloader, so in this
situation your session beans are not directly visible by reference to
your GWT module classes and visa versa, so they must be called
remotely (which means serialization).
One way around this is to set up yourEJBapplication as a Resource
Adapter ARchive (RAR). This is not normally used in applications as
such, and is usually associated with some external data source common
to a number of applications in an enterprise situation (a bit like a
database, it's comparable to a JDBC). Normally vendors use it, for
example Apache Jackrabbit uses a RAR. However this complicates things,
and I am not sure you will get optimal performance out of it anyway
(although I am not sure, I use RAR's but have never written one
myself), but it will probably perform better than using remote
interfaces to your session beans.
http://publib.boulder.ibm.com/infocenter/wasinfo/v6r0/index.jsp?topic...
For these reasons, unless you have the strongest possible reasons for
not doing so, I think your best bet is to include your GWT module in
your main enterpise application (so it is a WAR inside the EAR) and
then you will be able to call your session beans directly from GWT RPC
servlets using their local interfaces. This should give you the best
performance from the simplest code.

RPC Performance/Response Problem
First of all: Hi to everyone! I'm new to GWT and just programming my first app. Since i've some experience in Java it's not a big problem, but in this case i am stuck and hopefully someone can help me. In my app i make a RPC: On server side i get some data out of a database and save it into an array of type String. Up to 10.000 Strings atm, later on maybe up to 50.000. It is no problem so far. The server is handling this really fast. I measured 5 RPCs with about 500 Strings each and it took less time than 200 milliseconds each (SQL Statement + creating the array). The problem now is: I have to wait 5 SECONDS to get the results of the RPC (the String[] created on the server) on the client side so i can do something with them. Regarding the overall time i measured, these 5 seconds are more than 75% of the time which my app needs. Is it possible that the serialization and deserialization takes that much time? I don't think so and i have no clue where this 5 seconds come from. If someone has any ideas, solutions, suggestions on this problem i would appreciate any help! Thanks in advance, -Lord-67 P.s.: Of course i searched for a solution for this problem for hours, if i somehow just typed the wrong keywords to get the fitting results, just let me know and post a link :-). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

ScrollPanel problem in Chrome/Safari
Hello everyone.
I have this situation:
___
|ScrollPanel |
| __ |
| | AbsolutePanel| |
| | | |
| | ___ | |
| | | cell selector| | |
| | |__ | | |
| | | |
| | | |
| |_| |
|__|
When the users clicks the absolute panel (which has a background image
simulating a grid) the cell selector is moved in order to visually-
simulate the cell selection. It works fine on firefox and IE, but on
webkit-based browsers when the ScrollPanel has been scrolled and I
click on the absolutePanel, it automatically scrolls back the
scrollPanel to [0,0].
Any ideas? It is a bug in GWT or I must compute the [top,left] of the
cell selector in a different way?
Here is how I compute the cell selector's top and left:
[code]
public void clickAction(Event event){
int x = DOM.eventGetClientX(event)
- DOM.getAbsoluteLeft(getElement())
+ DOM.getElementPropertyInt(getElement(), scrollLeft)
+ Window.getScrollLeft();
int y = DOM.eventGetClientY(event)
- DOM.getAbsoluteTop(getElement())
+ DOM.getElementPropertyInt(getElement(), scrollTop)
+ Window.getScrollTop();
Calendario.eventsContainer.setWidgetPosition
(Calendario.eventAreaSelector, x - (x % CalUtils.getDayWidth()), y -
(y % CalUtils.UNIT_HEIGHT));
}
[/code]
Thanks in advance.

Re: problems in IE6 modifying DOM nodes
For anyone that's interested, the problem is solved by using the
correct document object. I started by using elem.ownerDocument instead
of document. However, I've found some gwt-docs that say you should use
$doc instead of document.

first I suspected a compiler optimisation bug but have since found
that a more straightforward call will not work on IE6. For example:
public static native void eval_js( Node elem, String evalCode )/*-{
elem.appendChild( document.createTextNode(Math.random()) );
}-*/;
Under IE6, catching the exception in GWT gives the following
information:
(Error): Invalid argument. number -2147024809 description: Invalid

Firefox and GWT hosted mode both work fine. The node concerned is
correctly attached both physically and logically. It seems that any
attempt to break into native script calls give the same problem.
Interestingly enough the following call works fine:
alert( elem.nodeType );
It seems as if the node is read-only???
Has anyone experienced this? I've been working one this for two days
now and have run out of work-around ideas.

deferred binding
I have been trying to find out if there is a way to use deferred binding to load code that has been compiled at different times. Most of the documentation is about a single compiler pass over the code. The reason I need this is because I am writing a framework that can host components in a type of builder application, a bit like say Visual Basic would be able to load ActiveX controls onto a pallet for a developer to use. It seems like dynamic binding is what I require and I have read that it is not available. I can already call JavaScript methods (using overlays etc) from my application which requests them from a remote database and loads them at runtime. This works great but of course, since I have to write the first set of components myself, I really want to use the GWT and not hand write them all in JS. I would also prefer my development team to use GWT as well.

Re: Two TabPanels, different CSS styles
Thanks a lot Gregor. I was struggling with remove the default styles
from the tabpanel. This is very helpful.
On Feb 27, 7:12 am, gregor greg.power...@googlemail.com wrote:
CSS is often hierarchical in GWT widgets. You have a primary style
name and then additional secondary styles that are swapped out
according to user actions (like select, hover etc). With a Tab panel
the tabs are controlled by the TabBar class, and you can see it has a
primary style gwt-TabBar and a selection of additional styles.
.gwt-TabBar {
}
.gwt-TabBar .gwt-TabBarFirst {
}
.gwt-TabBar .gwt-TabBarRest {
}
.gwt-TabBar .gwt-TabBarItem {
}
.gwt-TabBar .gwt-TabBarItem-selected {
}
To custom style TabBars differently all you have to do is copy this
template CSS and replace gwt-TabBar with my-TabBar. Then you set the
style as:
myTabPanel.getTabBar().setPrimaryStyleName(my-TabBar);
Do not change the gwt- part of the secondary style names as the
internal TabBar code won't recognize them. E.g. you end up with
.my-TabBar .gwt-TabBarItem-selected {
}
So you can have as many different styles for the same GWT widget class
within the same application as you like.

Re: deferred binding
There's nothing preventing you from writing the code in GWT. However, AFAIK, there's no support for dynamically loading GWT modules. You have to write your own framework for now as far as I know to do this dynamically. On Thu, Mar 26, 2009 at 9:34 AM, johnpearcey john.pear...@gmail.com wrote: I have been trying to find out if there is a way to use deferred binding to load code that has been compiled at different times. Most of the documentation is about a single compiler pass over the code. The reason I need this is because I am writing a framework that can host components in a type of builder application, a bit like say Visual Basic would be able to load ActiveX controls onto a pallet for a developer to use. It seems like dynamic binding is what I require and I have read that it is not available. I can already call JavaScript methods (using overlays etc) from my application which requests them from a remote database and loads them at runtime. This works great but of course, since I have to write the first set of components myself, I really want to use the GWT and not hand write them all in JS. I would also prefer my development team to use GWT as well.

GWT Serialization ???
Hi, I am new to GWT and I have been playing around with GWT. Now I want to retrieve via hibernate using a RemoteService call ths content from a database. I have already a jar (provided by the db guys) where the domain is reflected. The problem I have is when I use it I always receive serialization problems form some classes of the domain. I know that if I extend my entity classes wit IsSerializable than the serialization works fine and I have no problem. I have been reading around and found that if you add your class to the *.gwt.rpc file than this would to the trick, well for me it didn't work, still serialization problem. I googled and found the Gilead project (former hibernate4gwt), what I don't like is that I have to extend my entity classes, but I am not allowed I am not maintining the db classes. So I am a bit stuck and after googling for last few days I didn't manage to find a proper solution. How can I get rid of the serialization problem, any suggestions are welcome?

Re: GWT Serialization ???
If you don't have access to the source for your hibernate objects, then you'll need to create DTOs (data transfer objects) that are essentially identical to your hibernate objects. You can then manually marshal the values, or use a bean mapping library such as Dozer to do the work automagically. I generally use this technique even when I have the source for my server side objects as most of my objects have information that is not appropriate to send to the client anyway. -jason On Mar 26, 2009, at 7:41 AM, jero wrote: Hi, I am new to GWT and I have been playing around with GWT.

calling RPC service from Java using GWT 1.5
Hi
I'm trying to do what's stated in the subject. I thought I could use
javaongems to do that with the following code :
-
import org.javaongems.core.jclient.Gwt;
import com.google.gwt.user.client.rpc.ServiceDefTarget;
public class JavaRpcClient {
static public void main(String[] args) throws Exception {
Object myService = Gwt.create(my.package.MyService.class);
((ServiceDefTarget) rpc).setServiceEntryPoint(http://
service-url.com);
[...]
}
}
-
However when I try and run this code, I get :
Exception in thread main java.lang.NoClassDefFoundError: com/google/
gwt/user/server/rpc/impl/ServerSerializableTypeOracle
at org.javaongems.core.jclient.Gwt.create(Gwt.java:29)
at
org.bioversityinternational.webmgis.server.rpcclient.JavaRpcClient.main
(JavaRpcClient.java:14)
My guess is, ServerSerializableTypeOracle is an old class which is not
any more distributed with GWT (the javaongems jar I found is almost
2.5 years old). Well all this makes sense, but now my question is, is
there an alternative?
Thanks in advance,
Guilhem

The '!important' annotation is necessary.

You may want to search the archives of this list for some keywoards
relevant to what you're trying to do. Every now and then someone
asks, and the answer is always you can't get there from here.
GWT's RPC wire format is optimized for web-browser to web-server
communication. There are all kinds of implementation details that
assume the client is GWT-compiled Javascript. Hosted mode is
Java-on-a-JVM, so it's obviously possible to do what you're trying to
do, but the overhead is not worth it for real Java applications
(you'd have to either run hosted mode or re-implement the client-side
RPC goo).
You need to refactor your server to be able to handle the same
request from two or more different kinds of clients and funnel all the
requests through the same business logic. Complicating your clients
by making them speak GWT RPC is the path to insanity.

Re: How can I combine 2 projects into one with gwt 1.6+?
Hi Brandon,
I'm not clear why you would need to compile the sub modules independently
from the main module. The GWT compiler performs a monolithic compilation for
each module it compiles, therefore the submodules would be completely
independent from the main module if they were compiled separately. It seems
like if you want to reuse those submodules, the best way would be to
reference them from your main project (linking source in Eclipse, for
example), and adding the submodules to your main GWT compilation target as
shown in the ant snippet.
If you have server-side classes that you want to compile separately and
include in the main project, you should probably set up a build target that
will javac those classes and copy them over to the main GWT project
directory. The gwtc target would then be dependent on that step before being
able to perform its own GWT compilation.
Putting into context of your next goals, 3. would be solved by what was
described in the last paragraph. 1. and 2. might not need to be explicit
goals since compiling separately probably won't be of much value for what I
think you're trying to do. Although I may have misundertstood the purposes
for goals 1 2.
Hope that helps,

Hi Brandon,
I think the typical way to reuse an existing GWT module in another is to
package that module into a JAR file (source included) and then refer to
the
module from main project in its module XML file, as you did above. You
would
then add that JAR to any launch or compilation scripts so that all
references would be resolved while running hosted mode or the GWT
compiler.
In the same way, you would refer to this JAR in your ant build.xml file
for
gwtc or hosted mode startup targets.
You could also refer to the GWT module's source folder and classpath
directly, as you did in your Eclipse configurations. This should also
work
in Ant by defining the appropriate path element. Something like the
snippet below should do the trick:
path id=apple.class.path
fileset dir=../Apple/src/com/gawkat/gwt/apple/client
include name=**/*.java/
/fileset
/path
target name=gwtc depends=javac description=GWT compile to

java failonerror=true fork=true
classname=com.google.gwt.dev.Compiler
classpath
pathelement location=src/
path refid=apple.class.path/
pathelement location=${gwt.home}/${gwt.dev.jar}/
/classpath
jvmarg value=-Xmx256M/
arg value=com.gawkat.gwt.Test/

/target
This would be in addition to other path elements you would need to define
to
build your project.

Re: do i have to make showcase as a module and inherit this module in my projecc
Hi Coonay, The Showcase sample application is a GWT module, in the sense that it defines its own module XML file describing its GWT application structure. You could JAR it up and reference it with an inherits tag in your own module XML file to reuse its widgets, but I think that's far more effort than is necessary if all you want to do is reuse the RichTextToolbar. If that is indeed all you want to do, I would suggest simply copying the source code into your project and reusing it that way. You will need to do some minor tweaks to the source to adapt it to your project, but they should all be pretty straightforward changes to make. If you have any trouble, feel free posting up here to troubleshoot.

Re: How Can I Rebuild A Library From Source In Eclipse?
The GWT compiler requires the source (.java) files, and hosted mode works with bytecode (.class), so it is generally as simple as packaging all of the source and bytecode files into the jar. have a look at the gwt-user.jar for an example of what that looks like. The other option is to simply import the svn checkout (source) into eclipse, and use that with your project directly. Sometimes this is an easier route to go anyway, especially if you are modifying the source regularly. -jason On Mar 22, 2009, at 4:37 PM, Superman859 wrote: I use Eclipse for GWT, and I'm trying to use a third party library (OFC GWT) for charting. The most recent version of source code in Subversion repository seems to have the changes I require, but the downloadable JAR file doesn't have those changes in it yet. Can someone explain how I can take the source code and compile it to a usable JAR library for GWT? I can't seem to find this information anywhere, but it would be highly useful as I often want to fix a bug or two in some libraries when I try to fix them, but I do not know how to compile / generate the JAR library afterwards to test out and use my adjustments. In Eclipse, I know there is an Export - Jar File option. However, when I use this on the project, the 'resources' box on the left is empty, and no files will be added to the JAR file. I'm not sure if this is because there is no Main method (it isn't a typical Java program), or what it has to do with as I have never created a JAR library before. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Connecting to site 127.0.0.1
One workaround could be to change GWT port on every run, using command line option -port 8889 (e.g. making 10 scripts, each with different port).

Re: Back Refresh button handling
I'm in a similar predicament, perhaps you might have an idea of what
to do.
When the user closes the browser window, I want the application to
logout his/her session automatically so as to free up memory on the
server from their session. So I use the onWindowClosed() function to
take care of this... But when the page is refreshed, the session gets
logged out as well through the same function. This is something I want
to stop from happening. Any suggestions?

Hi
There is no way in GWT to distinguish betweenRefreshbuttonclick and
Window closebuttonclick. But you can trackrefreshbuttonwith a
little trick. You should use a time cookie which will expire after
some time. So whenrefreshbuttonis pressed, in on module load of
entry point , track the value of this cokkie, if this cookie is still
alive, this meansrefreshbuttonis pressed. The time this cookie will
expired should be considered. It should be very little.
Second for history, you should save your information in Session on
window close and then ifrefreshbuttonis pressed, get your
information from this session.

You can restore state, but it's a bit more work than just using GWT
History. Basically you'll need to come up with some way of modifying
the url search parameter (stuff after the #) to include some info so
that you can bring the userbackinto the same state as they were
before. For example, if your application has a number of screens and
they were on screen foo, which was loading with properties for an item
with id 10 then you'd need that information in the Url.
ex: http://yourApp.com/gwtHostPage.html#screen=foo_id=10
You could also put a conversation id in the url param and then keep
the fine details cached on the server, but that makes the state/data
more transient. If you go with an option like this though it can help
make your pages open and work in other tabs and even make points in
your application bookmark'able'.
Now for the easy answer, yes you can just prevent the user from
carelessly clickingrefresh. Fortunately there isn't a way to trap
somebody on a webpage (think about how bad the web would be). But,
you can use the WindowCloseListener to present a user with a
confirmation before they close the window, navigate to a new page, or
hitrefresh. It'd look something like this (not tested):
/
Window.addWindowCloseListener(
new WindowCloseLisener(){
public String onWindowClosing(){
return Are you sure you want to leave this application?;
}
public void onWindowClosed(){
// Cleanup if need be
}});

GWT provides History.onHistoryChange event to handle history but how
can we restore application state when a user clicks onRefreshbutton?
For example the user performed multiple actions on the web site and
then clickedrefreshbutton. Now how using GWT History class we can
restore the same state?
Another question, is there a way to trap Refresh click before
actually the app refreshes and can be cancel the event?

Would it even be possible to support the JRE WeakReference object? or in someway the weak listener support like done in Swing? Javascript has no concept of a weak reference, so we can't implement it in GWT. I think this is getting a bigger issue now that GWT is getting more used to make more advanced enterprise-like applications. My experience: In simple applications it's no problem to clean up your own objects and listeners, but in more advanced applciations that I am building nowadays with GWT, I noticed that this is a serious drawback and it's very easy to great memory leaks. You just have to design your app from the beginning such that you don't leak references. For example, the way native objects in the browser are implemented, you wind up with a reference cycle (the listener holds a reference to an element and the element holds a reference to its listener, and since the native objects are typically reference counted and not visible to the JS GC the cycles can't be collected), and the way we avoid leaks is to be diligent about when such cycles are created/destroyed (in this case attached to the DOM vs detached). If you are building your own listener structures, you need to have similar diligence. This is a general JS problem and GWT can't perform miracles -- well not that miracle anyway :). -- John A.

[gwt-contrib] Re: weak listener in GWT?
He John, Thanks for your answer. Not very unexpected, but I was hoping I missed something. This means that I have to do some more work when removing objects. My situation: I have pages that make up a wizard-like application (part of the application). The pages contain form field where the user fills in his name, social nr, etc.. When he goes back in the wizard tree and changes his birthday for example: other form fields on other pages are removed. However, they have a bunch of listeners subscribed to a global data model.

[gwt-contrib] Re: RR: testing -noserver hosted mode
On Tue, Feb 17, 2009 at 2:27 AM, Lex Spoon sp...@google.com wrote: Revision 3901 broke -noserver hosted mode, but it took weeks before anyone even noticed. I've been trying to figure out how to write a regression test to prevent that sort of thing from happening. Attached is a patch that I believe does the trick. Hosted mode gurus, as well as people who know the GWTTestCase infrastructure, would be very welcome to chime in on the right way to do this! I figure that a -noserver hosted mode test is actually pretty close to the existing hosted mode tests. There are just two differences I see. First, a compile needs to actually run. Second, all auto-generation of resources should be disabled in the GWTShellServlet. By turning off all auto-generation, the servlet can pretend to be a dumb web server that knows nothing about GWT. What the patch does is add a new run style called -noserver. This is a subclass of the regular hosted mode run style that includes the above two changes. The trickiest part is that RunStyle now has a parameter on whether auto-generation should happen with the embedded server. This parameter had to be passed all the way from RunStyle to JUnitShell to GWTShell to EmbeddedTomcatServer to GWTShellServlet. Any simpler idea would be welcome. Because it's easy, the patch also turns off resource generation for web mode tests. The reasoning is that it's a slightly better test of web mode to prefer the files that actually resulted from compilation. To get the test hooked into the build scripts, I added ant test.noserver in the user directory, and had this called when ant test is called. There is only one test that this runs: the IFrameLinkerTest. The other linkers don't work in noserver mode. Also, no other tests are run in noserver mode; I don't see a significant benefit to running the other ones this way, because once an app is booted up everything will be identical to regular hosted mode. John, if the general strategy looks good to everyone, could you review the implementation? Passing the parameter all the way down this way is ugly, but I don't know of any better ways to do it. I would prefer the new ArgHandler to be a top-level class, but I see the others are inlined as well so I am ok with keeping it. I don't see the build.xml changes for test.noserver. Otherwise, LGTM.
