gwt-dnd for FlexTable
Hi all, I want to use gwt-dnd library for FlexTable row drag and drop. The data which i am displaying in FlexTable is coming from database as ArrayList. I have another FlexTable rows of which are in co-ordination with the first FlexTable rows. When row of first flex table gets dragged and dropped i want to refresh the second flex table according to the index of row of first flex table. Both flex tables are in ScrollPanel. I saw example of gwt-dnd for FlexTable. But it is given that AbsolutePanel is required for DragController. How can I use AbsolutePanel? Can I use ScrollPanel inside AbsolutePanel ? Can anyone help me with this issue? It's really urgent... Thanks in advance..

Re: Different sessionIDs in one application
Hi Markus, Is it possible the SessionId Cookie hasn't been sent to the client when the second method is invoked? You may need to force the Server to create the HttpSession object and send the Cookie in your host page (or before you reach it). Basically any call to HttpServletRequest.getSession() should create the session and assign an ID to it, but until the response has been sent to the client, the browser won't have knowledge of that Session. Let me know if thats not the problem. //J Markus wrote: Hello I have following problem with my application.

Re: Loading Images into GWT via MySQL
Does the img.setUrl(data:image/jpg;base64,...-trick work reliable in
all major browsers?
On 13 Mrz., 15:07, Darren siegel.dar...@gmail.com wrote:
The one case that hasn't been mentioned is when one dynamically

We transform various XML data sources into SVG and then transcode into
JPG (using Batik) on the fly, then base 64 encode the JPG into a

Then on the client, once you have the image data from the RPC callback
(as a String):
String base64EncodedImage = ... ;
Image img = new Image();
img.setUrl(data:image/jpg;base64, + base64EncodedImage);

I think Itamar is right, Jack, you should use a standard HttpServlet
for this, not GWT-RPC, because this sends the image over to the
browser as byte steam, and I don't think RPC can do that.
First, I take it these are not images used in your UI (like icons
etc), 'cos those should go in an ImageBundle. I assume you know that
these images are downloaded as user selections etc.
1) Consult your MySQL docs/forum to find out how to obtain an
InputStream for the image via JDBC. You want to pass an InputStream
back to your image download HttpServlet. You don't want to read out
the image bytes yet.
2) You write the HttpServlet something like this example (there are
lots of others around):
http://snippets.dzone.com/posts/show/4629
Notice that the key is a looping read of the InputStream (which you
got from MySQL) that writes straight into the HttpServlet's response
OutputStream. Notice also it uses a buffer byte[] array. This is so
that your web server does not get it's memory clogged up with big
image byte arrays - the image bytes just get shunted from the DB
straight out to the browser via this buffer. Therefore set this buffer
small. Apache tend to use 2048 bytes. I think Oracle prefer 4096. That
sort of size for the buffer. Take care to set the response content
type so the browser knows what it's dealing with.
3) In your client you can set the Image widget's URL to your image
download HttpServlet adding a parameter for the image id.

best deploy for jnlp applet via GWT
Hi all, i am approaching GWT for the first time, trying to understand how to implement all functionalities required by my application. I currently need to access database, so I'll have to create some widget that load and store data via a servlet; this is not a problem. What I think might be a problem is scanning and sending all scanned pages to the server. In order to scan, I have an applet that I currently load via jnlp since it require a few extensions (JAI and JAI Image I/O). I could probably load the applet when the GWT application start, but then, I have to communicate with the applet when the user select to scan. I browsed all the archives of this forum and I found how to invoke applet methods from GWT code, but I failed to find a way to do the same thing when the applet is loaded via JNLP. Is there any way to communicate with applet ran via JNLP? Moreover I use JNLP instead of APPLET because I may specify how much RAM the jvm should use. (I need a lot of ram for storing buffered images.) Otherwise, I think I have to load the applet via APPLET tag, but I have no idea about how to deploy extensions and how to specify -Xmx using this tag.

Re: file upload like orkut
File upload is done via either: a) The FileUpload widget - if your happy for the user to select one file at a time, or b) Via a Flash Movie that allows multiple file selects. Which ever option you choose you would then build your UI on-top since you choose when to post the contents of FileUpload or the flash approach to your file uploading servlet (or other). If you don't want to roll your own flash movie / UI, and are happy to have a GWT wrapper around an existing library, you could try swfupload- gwt (http://www.ongwt.com/post/2009/03/14/A-GWT-wrapper-for-the- SWFUpload-library (via OnGWT)). From experience, if you do roll your own solution multiple select solution then you will never get it pure GWT since you need a) a flash movie and b) use of Flash's ExternalInterface command to make call backs to GWT and JSNI to make calls from GWT to the Flash movie. You also need make sure you cope with the new Flash 10 security restriction (must click on the flash movie to open the file select rather than before, where you could click on a GWT component and send that click to the flash movie). //Adam On 16 Mar, 06:51, vaibhav.saxena vaibhav@gmail.com wrote: Hi, I want to have the widget like the orkut photo upload.

Re: Different sessionIDs in one application
I think the problem here is specific to the long polling case mixed with RPC. If the first call that requests a Session is in the long polling method, while the second call (to the other method) occurs before the long polling method has completed: the browser won't have received the Session ID cookie from the first request (since it hasn't returned yet). You could test this by using HttpSession.isNew() in each of the Servlet methods to see if both requests have created their own session. Putting a dummy request for a session into a Servlet or JSP when the host page is served establishes the session with the client, since the page content will have a Cookie header containing the Session ID the browser needs to send to all the RPC methods. It's not the client code setting the Cookie, but rather the Servlet Container setting the session ID with the client so that the client will request that Session in subsequent invocations. Hope that explains my thinking a bit better. //J djd wrote: So just making a dummy call is enough? i.e. 2 method calls one after the other (in client code) will result in different IDs?

Possible cause's of onSubmitComplete not fired ? (content type text/html, form not hidden)
onSubmitComplete dosnt seem to be firing on my form, yet firebug shows
the request is returned and no javascript exceptions are fired :-/
I read a few threads on this group, but nothing seems to apply to me.
The response headers I get back are;
Server - Apache/1.3.41 (Unix) mod_log_bytes/1.2 mod_bwlimited/1.4
mod_auth_passthrough/1.8 FrontPage/5.0.2.2635 mod_ssl/2.8.31 OpenSSL/
0.9.8b
X-Powered-By -PHP/5.2.8
Keep-Alive timeout=15, max=100
Connection - Keep-Alive
Transfer-Encoding - chunked
Content-Type- text/html
Which is ok right?
I also get the response returned correctly according to firebug.
However FormSubmitCompleteEvent never seems to fire. (FormSubmitEvent
does)
Heres the code for the form;
==
LoginForm.setMethod(FormPanel.METHOD_POST);
LoginForm.setEncoding(FormPanel.ENCODING_MULTIPART);
LoginBits.add(LoginFields);
LoginForm.addFormHandler(new FormHandler() {
public void onSubmit(FormSubmitEvent event){
Window.alert(logging in4);
}
public void onSubmitComplete(FormSubmitCompleteEvent
event) {
Window.alert(logged in);
/* lots of code commented out */
}
}
(LoginFields is a horizontal panel containing the fields)
I get the logging in 4 but not the logged in.
Also, the form is never hidden.
Any ideas for other causes?

Hello, The scenario is the following. I have a flextable with some textboxes in it. When a value pressed in a textbox isn't what i expected i call a Dialog Box with an error message. My question is if it is possible to get the position of the 'erroneous textbox' and show the dialog box in the previous cell. For example my table 0, 0, Label 1 0 , 1 , TextBox 1 1, 0, Label 2 1 , 1 , TextBox 2 If the TextBox 2 is wrong then i want to place the DialogBox in the 1 , 0 position over the Label 2. How can i do this automatically??? Ty in advance. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: On-The-Fly compiling
It seems like a use case that is not going to be around for too long. My recommendation would be to use OOPHM- you get to use your target browser (I've only tried Firefox - haven't been able to get IE working), but run with all the benefits of Hosted mode such as dynamically updated client (hit refresh) server (restart the jetty server which costs nothing) code step-through/breakpoint debugging of both client server Java code.

Re: GWT RPC Serialization\Deserialization time
Before I explain an OK first-order approximation, ask yourself is it really worth the time to worry about the serialization/deserialization cost? I can tell you from first hand it's minimal compared with the typical code I've written. Now maybe if your passing in large amounts of data (think megabytes), the story might be different. At which point you've got to be wondering why do you actually need to transfer that much data wouldn't it be better to split up the result in chunks - highly unlikely the user is going to need that much data. And at that point your bigger costs are probably going to be actually transferring the data across the network. Now that I've had my spiel about the dangers of micro-optimizing, I'm giving you the tools to shoot yourself in the foot (in terms of wasting your time). I dunno if it's strictly possible without actually modifying the code. You could always add instrumentation to the GWT code rebuild your own flavour of it (simply get the timestamp difference surrounding the (de)/serialization add that to a global diff value update the amount of times it's been called. Then you can keep a running average of the cost that you can query at any time. If that scares you, you could try to estimate it, but only if your client server are the same machine. Right before making the RPC call, store the current timestamp in a local variable. On entry into the RPC call, store the timestamp in a local variable put a breakpoint right after. The difference between the two times is the cost of going through the client communication stack (serializing parameters, making the AJAX request, creating the network packets, sending them to the server, handling the packets by the server, handling an AJAX request by your app server deserializing your parameters. Working on the assumption that the most expensive part of that process is serialization/deserialization (which is reasonable cause transmission time should be 0, and since it's a socket-to-socket communication on a local machine, you shouldn't see any significant latency overhead in the kernel - maybe 100 us at most), then you can estimate how much time that took.. Repeat the process by recording the exit time (this would have to be in a global variable) from the RPC call the time on the client when the call returned. This will give you an idea of the cost of serializing the return value. This is a good-enough first-order approximation. Note, that if you want this to be done in a logging fashion, you'll have to include the timestamp in your RPC request parameters result which might skew your results (do not print timestamps as that definitely screws things up because printing to screen is relatively expensive when your dealing with these kinds of microbenchmarks).

Re: Need help with callback
That's because GWT doesn't know you actually need the errorHandler name.
It'll mangle it to improve performance when compiling (by minimizing the
size of your javascript).
What you need to do is instead of giving it errorHandler, pass it a
Javascript function you create (on every call or cached in the page
somewhere) which then calls your Java code using JSNI although, since it
seems like you want to do the error handling in native Javascript (why?),
you don't need the JSNI part. Same goes for the dataHandler.

Re: GWT Hosted Mode SSL on Ubuntu 8.04 - need help please!
I had exactly the same problem on my Ubuntu 8.04 system. My workaround was to disable SSL while I was debugging in hosted mode. The final testing was done on a compiled version in Firefox with SSL enabled. I see, though, that you may not be able to disable SSL so easily. I might try Ross's fix if I get a chance.

Not only did downgrading the libnss3-1d package lead to another error (the PSM popup box) but it also caused me to lose a couple hours chasing down why my YouTube videos stopped playing in Firefox. You bet it, they were related. The adobe flash plugin is linked to libnss3-1d and downgrading corrupted it, cheers to the original fix! So, after upgrading back to the latest libnss3-1d I was back to the original crash bug on the redirect to the secure site: SIGSEGV (0xb) at pc=0xb7fbe540, pid=3168, tid=1988291472 yay. Well, at this point I started to look into the GWT code, noticed in 'BootStrapPlatform.java' that it was searching mozilla installs in 'mozilla-hosted-browser.conf' and that I could control the shared library loading in the 'gwt-linux-1.5.3/mozilla-1.7.13' with the magical file 'gwt-dl-loadorder.conf' After a lot of hacking, and finding some examples of 'gwt-dl- loadorder.conf' in the gwt-contributor forum... I arrived at a beautiful hack which fixed the problem!

Re: Strange List serialization behaviour
Progress ... of a sort. I think this is something to do with the way we package our GWT service handlers into OSGi bundles. I don't really understand how the GWT serializer and proxy code works ... but ... the thing that is different about this new service handler class is that it exists in a different package and bundle to our normal GWT service handler classes. If I move it into our xx.xx.xx.server package, bingo, it all starts working. My guess is the reason comes down to 1 of 2 things: - the GWT compiler wants to scan all xxxServiceImpl classes that use RemoteServiceServlet to deliver an RPC service as part of it's proxy generation - there is some package/class resolution failing which causes the seriallizer code to fail The latter is very common in OSGi, but I don't see any errors to suggest that happens in this case. What's strange is that this only seems to effect the two services returning ListE types - and the class in a different package and bundle breaks both of them. That kind of suggests to me that there's some generic ArrayListE serializer being used for both these cases, and because one of the services exists in a different package that wasn't scanned by the GWT compiler, it somehow breaks both cases. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Create a folder called MyApplication.war, make sure you add the .war on the folder name. put there your compiled gwt files, which should include your .js and .html and all the other static file. so let's say your compiled module in MyModule so now we have MyApplication.war--MyModule--index.html/module launcher.html Next in MyApplication.war, create a folder called WEB-INF inside this folder you will have the following: folder called classes, lib, and web.xml in web.xml you have the servlet mapping, in classes you have the impl of your rpc servlets if any exist and in the lib folder you add there gwt-servlet.jar sure you can automate all this using maven/ant scripts. but as a start give it a try like that and it should work for you. nothing to configure on JBoss if you're not using seam/llooking up your EJBs from your rpc servlet impl. regards, ruds On Mon, Mar 16, 2009 at 4:24 PM, tetsuo tetsuomeis...@googlemail.comwrote: hello folks, since a couple of days (within weeks) i tried to get the gwt running on a jboss. fortunately it runs on the tomcat 6, but that isn´t my primary target-server, so the wish was, to port the gwt on the jboss, but it is like hell. no remote calls from the client/js side are running thru the chain of proxy, interface and the implicit class on the ejb side. the configuration of a jboss is not that easy, as a tomcat would be, so its quite a lot of things to do within the xml hell there. hopefully its solved, the gwt dos´not get a single tone from the server. my question is, why is there no complete example, on how to run the gwt on a application server ? a distributed server 3-4 tier environment is more than a handful of clustered tomcats at all, so who got the clue, to glue that stuff together. let me know, where i can find a configuration and sample code - completelyand ootb for easy to understand brain, like me. all the code snippets, without correct version number are pain in the ... dont waste a byte for sites like this. it is a quest(ion) for the developer on google, i want a primary answer, that forum should be the place for that issue. have a good day, should be more satisfied than mine. cheers tet p.s. the gwt-on-seam is the same lame example without practical function - that theoretic should run is also crap, have´nt seen a single running example :/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: gwt.1.5.3 on jboss.5.0.1 with ejb3 notation
You will always need the Tomcat container to host your RPC servlet. In order for your GWT module to communicate with your server, you will need an interface that extends RemoteService which needs to be present in a Servlet container. From there you will have to look up your ejbs and with EJB3.0 it is easy to do it, you just create the IntialContext and look up your remote beans. I have done a full flow from client--tomcat COntainer-- App server layer-- ORM(Hibernate) and back with the flow to the client. all the configuration needed on JBOss are 2 xml files that you need to change so you can call your EJB remote interface from your rcp servlet that is hosted over tomcat.

Re: best deploy for jnlp applet via GWT
When you talk about JNLP vs. applets, are you talking about a JNLP *application* vs. an applet? If you are talking about a JNLP application, then as far as I know there is no way to communicate directly between GWT and the JNLP application. I had a similar requirement, and I eventually had the GWT application and the JNLP application talk to each other through the server. A key point to remember with JNLP applications is that they run completely independently of the web browser and so cannot talk with code running within the Javascript sandbox. Is it acceptable if your application relies on recent versions of the Java Plugin (Java 6 Update 10 and later)? If so, you can have the best of both worlds, a JNLP applet. See: http://blogs.sun.com/javaone2008/entry/applets_reloaded for a brief description. Basically, the JNLP applet is launched via the APPLET tag and runs in the context of the web browser (just like a traditional applet). Although I have not tried this, it should be able to communicate with Javascript. I have not used it, but the GWT AI project: http://code.google.com/p/gwtai/ provides a GWT/applet integration layer. One advantage of JNLP applets over traditional applets is that, as with all JNLP applets and applications, the applet will be cached on the user's computer (eliminating the download wait after the first launch of the applet). If applet download time is why you are considering launching the applet when the GWT application starts rather than when the user requires the applet's functionality, a JNLP applet may be responsive enough so that you can launch it on-demand (eliminating the need to communicate between Javascript and the JNLP applet). As you know, using the JNLP descriptor file, you can specify how much memory your applet needs. Alternatively, as of Java 6 Update 10, you can specify how much memory your applet needs through the applet tag.

What I think might be a problem is scanning and sending all scanned pages to the server. In order to scan, I have an applet that I currently load via jnlp since it require a few extensions (JAI and JAI Image I/O). I could probably load the applet when the GWT application start, but then, I have to communicate with the applet when the user select to scan. I browsed all the archives of this forum and I found how to invoke applet methods from GWT code, but I failed to find a way to do the same thing when the applet is loaded via JNLP. Is there any way to communicate with applet ran via JNLP? Moreover I use JNLP instead of APPLET because I may specify how much RAM the jvm should use. (I need a lot of ram for storing buffered images.) Otherwise, I think I have to load the applet via APPLET tag, but I have no idea about how to deploy extensions and how to specify -Xmx using this tag.

Now when I launch it I get the following exception in the shell [WARN] StandardWrapperValve[shell]: Servlet.service() for servlet shell threw exception java.lang.NoClassDefFoundError: null at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:164) at com .google .gwt .dev.shell.GWTShellServlet.tryGetOrLoadServlet(GWTShellServlet.java:936) at com.google.gwt.dev.shell.GWTShellServlet.service(GWTShellServlet.java: 277) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org .apache .catalina .core .ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java: 237) at org .apache .catalina .core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:157) at org .apache .catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java: 214) at org .apache .catalina .core.StandardValveContext.invokeNext(StandardValveContext.java:104) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java: 520) at org .apache .catalina .core.StandardContextValve.invokeInternal(StandardContextValve.java:198) at org .apache .catalina.core.StandardContextValve.invoke(StandardContextValve.java: 152) at org .apache .catalina .core.StandardValveContext.invokeNext(StandardValveContext.java:104) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java: 520) at org .apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java: 137) at org .apache .catalina .core.StandardValveContext.invokeNext(StandardValveContext.java:104) at org .apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java: 118) at org .apache .catalina .core.StandardValveContext.invokeNext(StandardValveContext.java:102) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java: 520) at org .apache .catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org .apache .catalina .core.StandardValveContext.invokeNext(StandardValveContext.java:104) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java: 520) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java: 929) at org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter.java: 160) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java: 799) at org.apache.coyote.http11.Http11Protocol $Http11ConnectionHandler.processConnection(Http11Protocol.java:705) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java: 577) at org.apache.tomcat.util.threads.ThreadPool $ControlRunnable.run(ThreadPool.java:683) at java.lang.Thread.run(Thread.java:613) If I remove the field that instantiates the class above I get no warnings nor exceptions.

Interesting issue for experts!
I just created hibernate POJOs for three new tables using weblogic
workshop, all these 3 classes have this:
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;
import org.apache.commons.lang.builder.ToStringBuilder;
That makes my build to fail (it wasn´t failing before this change):
[java][ERROR] Errors in 'file:/C:/CAPWL/src/org/eagle/cap/

[java] [ERROR] Line 96: No source code is available for

The section of build.xml where the error happens is:

So it seems that those imports (necessary for the equal method so I can
´t jus remove them) are spoiling the whole thing...comments and help
are highly appreciated.

Re: How to align TabPanel on right
Not sure, but TabBar has the styles:
# .gwt-TabBar .gwt-TabBarFirst { the left edge of the bar }
# .gwt-TabBar .gwt-TabBarRest { the right edge of the bar }
so if you give TabBarFirst 100% width and give TabBarRest maybe a
fixed width to give you a little indent from the right edge if you
wanted one, it might push the tabs over.

You have two choices: port
org.apache.commons.lang.builder.EqualsBuilder,
org.apache.commons.lang.builder.HashCodeBuilder, and
org.apache.commons.lang.builder.ToStringBuilder to GWT or stop using
them. I'd recommend the second choice (not using them).

Re: Need help with callback
On Mon, Mar 16, 2009 at 5:12 PM, dean.mikel dean.mi...@gmail.com wrote: Thanks very much for the response. What you need to do is instead of giving it errorHandler, pass it a Javascript function you create (on every call or cached in the page somewhere) which then calls your Java code using JSNI although Ok, so I could use a closure anonymous function in place of the callback arguments. Then inside the closure I would would use JSNI to call my java dataHandler method? I'd have to process the callback parameters inside the closure, for example to convert the result set to array, because Java side won't understand SQLResultset type, correct? Or is there a better way? Yup - that's the word I was looking for. Closure. Well, you see, it's kind of pointless to use a closure to just wrap a call to dataHandler. You could just pass in dataHandler (using JSNI). The cleaner approach (as far as I know, and somebody feel free to correct me), would be to write an overlay type for SQLResultSet (an extension class of JavascriptObject that uses JSNI to retrieve values - a google search should give you a nice overview). Then you pass in your dataHandler via JSNI, but make it a non-native method that accepts your overlay. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: NoClassDefFoundError
You'd have to provide more code. It sounds like your trying to do the following: private MyClass foo = Class.forName(MyClass.class).newInstance(); in your RPC class. It's quite possible that that throws an exception, which means GWT can't initialize your servlet. My recommendation would be to put that in your constructor, surrounded by try/catch blocks. Lemme know if that helps. If it is throwing an exception, then you'll have to figure out why it's not really on your class path (I'm pretty sure for the server libraries, depending on how you're launching, it has to be in your WEB-INF/lib directory).

Re: Interesting issue for experts!
This question keeps coming up - maybe it should go on the FAQ for GWT. With
like giant flashing arrows pointing to what you have to keep in mind when
developing GWT.
GWT is a client-side library (with some syntactic sugar for communicating
with a server backend more easily). Although you write Java, it's
javascript. That should explain to you why GWT won't compile your code -
because those classes aren't on the classpath they're not modules (and you
really can't include them because it's highly likely they use stuff
Javascript doesn't support).
Here's my recommendation. Create a POJO wrapper you use on the server that
implements those methods. When you communicate between the client server,
you pass the raw POJO, but the server always wraps the POJO in a richer
class that has the more advanced functionality you need.

Fixes issue 3474. If a method in an async RPC interface
returns a Request or a RequestBuilder, previously ProxyCreator
would generate uncompiling code. Now, such methods always
return a Request or RequestBuilder, albeit sometimes a dummy
stand-in object that always fails.

[gwt-contrib] Re: Changed gwt.xml not picked up buy webserver
I dunno - I applied the patch for hosted mode that was posted a while back. I'm pretty sure it's hosted mode - otherwise, my project wouldn't run without me having to redo the 1.5 project structure. Maybe I'm not understanding what you mean by GWTShell. The main class that is launched is HostedMode. So what I was trying to do was change the theme that was being used by my module by updating the gwt.xml file. Then I reloaded the web-page to get it to pick up the change, but instead I got the error unable to find module My set up is as follows: MyModule.gwt.xml - contains my project description - rename-to set to mymodule MyModuleHosted.gwt.xml - contains project description w/ user-agent set 1 localization set so that compilation is faster (renamed to same name as MyModule). Load ModuleHosted. Hit website to ensure that everything is working fine. Change the theme (inherits name='com.google.gwt.user.theme.standard.Standard'/ to some other valid theme). Hit Refresh Message [ERROR] Unable to find 'mymodule.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source? So it looks like it may be trying to lookup the wrong descriptor - instead of trying to lookup the description of the original file it was loaded with, it gets confused tries to load the module name.

There's something I'm not understanding about your setup. You say you're using HostedMode and the 1.6 project structure, but then you also said you were using OOPHM. How is that possible? OOPHM doesn't support the new project structure. On Mon, Mar 16, 2009 at 9:51 PM, Vitali Lovich vlov...@gmail.com wrote: I dunno - I applied the patch for hosted mode that was posted a while back.

[gwt-contrib] Re: code review requested - add OOPHM support for HostedMode
I'm not 100% sure if this is related to the patch, but I'm seeing an issue in the following situation: Started a project in OOPHM HostedMode Firefox 3.1 with plugin (version bumpbed to 3.1). Put laptop to sleep On wakeup, Firefox locks up. Now some variables do change - the connection drops out temporarily while the wireless is reconnecting to a different network (the laptop is moved to a different location while it's sleeping). Can anyone else confirm this issue? Obviously it's not the ideal set-up with FF3.1.
