Re: SerializerBase.check(String,int) throws useless exception?
I just had to debug one of these errors. I just set a break point where the exception is raised (i.e. SerializerBase.java:161). I ran my app in debug developer mode and when I hit the breakpoint I was able to inspect the parent call in the stack where there is a method parameter called instance. This will hopefully highlight the offending class where you should make sure it follows Sri's previous recommendations. I mostly get these errors where the RPC call is given a class which is itself OK but has had a non-serialisable payload assigned to it somewhere (e.g. as part of a Command pattern). So, I'm not sure that much can be done by the compiler to raise such conditions. As a quick method of getting the compiler to flag up possible RPC errors, I modified the payloads for the offending commands to avoid vague types like Object and instead used Serializable. (I'd normally avoid using Object but I'd inherited the code ;) You're right though - the exception message for this error case is unhelpful and should at least additionally use information from the serialisation target instance where RPC type information is not available.

Does anybody have tips on what to do when you get this exception? I've encountered one case: don't have fields of type java.lang.Object in your GWT Serializable classes. Is there more?

Re: OOPHM is slow
Tim, Are you filtering your Hibernate objects or translating them to DTOs (to remove dynamic proxies etc) before serialising them? If the answer is no to the above, then you might be falling foul to circular references or Hibernate fetching more data than you expect. As an experiment, is it possible to try hardcoding some of your objects with a minimal data set and see how your app performs? Cheers, Chris. 2010/1/12 Tim Mattison timmatti...@gmail.com I changed my debug level from Info to Debug and got lots of additional output but nothing that looked like it was the culprit. My application runs like this: 1) onModuleLoad is called, builds the UI, and fires off a GWT-RPC call 2) The server receives the GWT-RPC call, connects to a Hibernate database, pulls some data (~150K) and sends it to the client 3) The client receives the response and populates a FlexTable with the data Between 2 and 3 is where the storm of traffic occurs. With the new debug level I don't really get much more insight since I see that Jetty has sent the response to the browser and that's it. I have breakpoints set on my GWT-RPC callback's onFailure and onSuccess method and it doesn't get to either of those branches until minutes later.

I've tried all of the recommendations about changing the URL to include only localhost or 127.0.0.1 but I still have to wait nearly three minutes for my application to start. The program I'm writing is currently very small and only consists of less than 200 lines of code. It does import a JAR that contains definitions of a lot of objects and has some dependencies (Gilead, Hibernate, GXT) for the server side components but right now I'm just using basic GWT components. Does the size of the dependencies and included JARs matter? I ask because I notice that as soon as I start the application the traffic on port 9997 to and from my loopback interface is pegged at 1.5MB/sec in each direction for the entire three minutes the application is starting up. I stepped through my code with a debugger and the client side code gets set up, runs, then there's a three minute pause where all of this data goes back and forth, and then the server-side code runs. The client and server side code takes less than 1 second to finish so I don't think it's a bug in my code. I tried to capture the traffic in Wireshark to figure out what is getting sent but it looks like all of the packets are very small (~56 bytes) and trying to capture the whole session causes Wireshark to crash. Is anyone else seeing this loopback traffic problem? I assumed maybe the debugger is communicating my dependencies to the OOPHM
Re: OOPHM is slow
Hi Tim, It's still conceivable for a circular reference (or at least massively repeated objects) to be at play here. Your response size is 165739 bytes *compressed* size - many identical objects could compress to something relatively small and their expansion could cause issues. Also with Hibernate you most likely won't see a lot of database traffic from repeated objects as subsequent fetch requests will hit the session's level 1 cache. A quicker test could be to temporarily disable gzip encoding in your browser, for example here are instructions for FireFox: http://kb.mozillazine.org/Network.http.accept-encoding With gzip disabled, what size response does Jetty report? BTW - which browser are you using? Cheers, Chris. http://kb.mozillazine.org/Network.http.accept-encoding 2010/1/12 Tim Mattison timmatti...@gmail.com That's what I thought originally but I can see that it's only pulling back 165739 bytes from the RPC. When I don't return anything it turns out that it runs quickly so it obviously must be related to that. I'm not using DTOs but where is it trying to fetch the data from if it's not getting pulled back from the POST? I don't see any traffic to the database server so it must be doing something weird locally (like a circular reference as you suggested). Shouldn't it give up on circular references a bit faster than that if that's the case?

Before I ask my question I'll provide some info on the work I'm doing related to the question: I am working on massive(MASSIVE) enterprise GWT[2.0] application. The app currently consists of 3 java projects of which one is GWT(with entry point) and the other two are common type of lib's used by the main GWT app. The app also uses Ext-gwt[GXT] Now when compiling we use 2.1gig of Xmx and 2m of Xss - Build Server. This takes about 30 minutes on our build server(get it now? MASSIVE!) Righto, so here's the question : How can I speed up my local machine memory footprint? I have set the project to compile only one permutation (ie8). I provide 2m Xss and 1500(+/-) Xmx This still fails with OutOfMemoryException and I cant provide it with more due to my x86 OS. With GWT 1.7 i was still able to pull of a build locally albeit slow. DraftCompile is not an option as I want to do IE performance testing with gwt 2.0 as well as soyc and runAsync. On the up side... I do get a partial soyc but i can't pump my war onto apache because the compile never finishes. I've read around and it seems i cant split the 3 projects as GWT compilable modules that work as one.

Re: Increased compile resource performance[excluding draftCompile] with single perm
Are you sure that you need the 2mb stack? I seem to recall there was a problem a while back with stack overflows resulting in some people suggesting large stacks. I think that's been fixed now. Are you using a 32 or 64 bit JVM? What are the exact compiler and JVM arguments you are using? Cheers, C.

Re: Increased compile resource performance[excluding draftCompile] with single perm
Yikes, that's a lot of memory! I missed the note regarding x86 in the OP, so that puts you on a 32bit JVM. Have you thought about renting a High Memory EC2 instance over at AWS for a couple of hours? C. On Dec 15, 2:06 pm, Lukas Herman herni...@gmail.com wrote: SOYC option on large project takes immense amount of memory and hdd space. However, runAsync splitting is compiled properly without - draftCompile switch. I have ended with -Xmx32768m java memory for GWT Compiler using -soyc command line switch (i guess 8GB+ is sufficient). The generated files took over 2GB space on the hdd, and it took over 40 minutes to finish. There are 130 split points. Normal, production build takes less than 2 minutes per iteration. Hope this helps. Lucas On 15 pro, 10:05, Gerhard Davids glacieredp...@gmail.com wrote: Hi Folks, I'm currently sitting with my hair in my hands.

Re: Cannot find generated I18 UiBinder Files
Right - I only found a .properties file in my project's extras folder
if the -soyc compiler option had been added or if I explicitly
specified the extra directory location using -extra. Without either
of these explicit compile time parameters I get *no* properties file.
Also beware of the generateFilename attribute. Yes a different
properties file is _generated_, but the associated Message interface
does not use it so you still have to rename the properties file back
to the default naming convention and place a copy located in the same
location as the .ui.xml in order for it to be picked up at _runtime_.
I finally have some UiBinder code using i18n but it needed a
frustrating mix of guesswork and picking through generated assets to
get there - hopefully the documentation will be amended soon.
Cheers,
Chris.

@benzheren, yes, and sorry it doesn't yet do the extra bit by
default. I think the best thing to do is add these attributes to your
root ui:UiBinder element:
ui:generateLocales=default
ui:generateKeys=com.google.gwt.i18n.rebind.keygen.MD5KeyGenerator
ui:generateFormat='com.google.gwt.i18n.rebind.format.PropertiesFormat'
This will generate a .properties file for each template (look for it
in the package's -aux directory, e.g. com.me.my.app-aux/
com.me.my.app.MyWidgetImplGenMessages?.properties). These particular
settings will make the name of each message string an MD5 hash of its
contents, so that your translations won't get mis-mapped as things
move within the template.
At risk of sounding like a lemon, I cannot find the aux folder
anywhere - is this something that should be generated automatically?
From my first post, the compile output suggests that I should have a
file called
com.example.client.MainViewMainViewUiBinderImplGenMessages.properties (or
at least a file called
MainViewMainViewUiBinderImplGenMessages.properties) sitting
somewhere but even a search of all files using the following from
cygwin does not reveal anything:
$ find /cygdrive/c -iname *MainView*.properties 2 /dev/null
(Yields nothing)
Can anyone offer me any tips for tracking this down?

Re: OOPHM is slow
Something else I've just noticed - if you have an AV product installed then check its activity when refreshing your GWT app in OOPHM.

Re: OOPHM is slow
And another thing (sorry if these updates are getting excessive) Even despite the previous tweaks, Firefox was using some high levels CPU on app refreshes; I noticed that there was an addon installed as part of my Kaspersky installation called Kaspersky URL Advisor plus a few other plugins that I generally use from day to day. After the difference that configuring Kaspersky made in the last post, I was immediately suspicious of this. To eliminate these from FireFox I created a new blank profile for GWT development. To create a new profile launch firefox with the - ProfileManager flag and you will get a GUI to, well, manage your profiles. In the new profile, I cleared out all default addons and installed only the GWT developer plugin and Firebug. Now my application refreshes in 5 seconds - much, much better!

Should it be required to implement an specific parser for such a class

Cannot find generated I18 UiBinder Files
I've been trying to test the I18 features of UiBinder but I cannot
locate the generated properties file.
My procedure is this:
* Generate a new GWT 2.0 project called I18Test, with a package called
com.example
* Using the plugin, add a UiBinder asset called MainView to
com.example.client. I amended the generated code as follows:
!DOCTYPE ui:UiBinder SYSTEM http://dl.google.com/gwt/DTD/xhtml.ent;
ui:UiBinder xmlns:ui=urn:ui:com.google.gwt.uibinder
xmlns:g=urn:import:com.google.gwt.user.client.ui

.important {
font-weight: bold;
}
/ui:style
g:HTMLPanel
ui:msg description=Hello messageHello/ui:msg,
g:Button styleName={style.important} ui:field=button /
/g:HTMLPanel
/ui:UiBinder
* As a quick hack just to get the panel to show, I just amended the
generated module entry point to add the following:
RootPanel.get(sendButtonContainer).add(new MainView(Click me));
* When I run the app, everything appears okay. When I compile, I get
a message reporting that a file called

Re: Deploy RCP in a subdomain
SOP basically says that the GWT app can only talk to the domain from where it was served. With that in mind, I think you have two options: 1. Configure the web server for your primary domain to proxy your GWT requests to your sub-domain - mod_proxy for Apache will achieve this; or 2. Simply serve the page containing your GWT app from www.gwt.mysite.org. That could be either a full redirect to that server, or maybe even serve a static HTML file + GWT app from www.gwt.mysite.org into an iframe of the main site. The latter suggestion is not pretty, but might work for you. I hope that helps, Chris.

Re: rpc serialization problem
Are the List fields on your objects specified in terms of interfaces? GWT RPC needs to know as much about your objects at compile time, could you try using a concrete class instead - preferably ArrayList? It sounds like you're trying to serialize ORM objects directly, is that right? I don't know much about Data Nucleus and whether or not it dynamically enhances entity objects under its control with proxies etc. My experience is with Hibernate which usually does add something to a class, so serializing entities directly is strongly discouraged - either the entity objects have to be filtered of the Hibernate extras, or values copied into DTOs.

Re: GWT serialisation too slow
Not having a JIT may be really biting you here. AFAIK GWT serialisation makes extensive use of reflection, however there seems to be a way to define a custom field serializer (looks similar to using Externalizable), but I've not tried this myself: http://books.google.co.uk/books?id=KXBdajKMJGECpg=PA164lpg=PA164dq=gwt+custom+field+serializersource=blots=w5LGABPcqRsig=JRqZoeXztC7rG9jxftP_6QbbWwMhl=enei=0syfSqSsIIPUjAf77Jm9Dgsa=Xoi=book_resultct=resultresnum=9#v=onepageq=gwt%20custom%20field%20serializerf=false Good luck and if you decide to try this approach I'll be interested to hear how you get on.

I'll check out VisualVM, but I suspect that it's not up to running it. Annoyingly the machine is perfectly capable of running the actual *application*. The actual logic takes a tiny fraction of the time of the serialisation. My development machine is a traditional ix32 box and serialisation takes a trivial amount of time. I'll try the trick with the filter to get some actual figures. [...] How large are your serialized objects prior to compression? I think you can quickly test this by disabling gzip compression in FireFox: http://forgetmenotes.blogspot.com/2009/05/how-to-disable-gzip-compres... This just causes the page to turn into garbage --- probably a server misconfiguration on my end. If the uncompressed size is particularly large then memory and compression time may be the limiting factor. Looking at the server stats its VM size doesn't appear to change during the first serialisation process, indicating that it doesn't want to allocate more memory. I have a feeling that memory's not the problem. Finally, what kind of objects are you serialising? Are you attempting to send something like Hibernate objects over the wire (or some other kind of proxied objects) which are causing unexpected database hits? Nope. The entire DB is being held in-memory. In fact, the way my app works is that the server logic calculates the delta needed to be sent to the client, constructs a packet of client objects from this, and then returns that packet as the result from the RPC call, so the stuff being serialised doesn't actually content to the objects in the DB at all. (My 400-object delta, the result of the initial DB sync, takes about 4s to generate.) The delta generation uses reflection and annotations to query the DB objects for properties that need to be copied into the delta. (The client is only allowed to see information from the DB that the user is allowed to have.) Simply by adding a cache for Field objects I managed to reduce the time taken for the delta generation by a factor of ten, so I suspect that reflection is dog slow with this JVM. What does the GWT serialisation system use? If it uses reflection, is there any way of persuading it to use byte-code generation instead? -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ─http://www.cowlark.com─ │ │ They laughed at Newton. They laughed at Einstein.

Re: GWT serialisation too slow
Morning David, I've found that GWT serialization is pretty decent. 500-600 does seem like a lot of objects to be processing in one hit if performance on a low end server is a concern, but then again 20 seconds seems like an awfully long time too. What's the performance like in your dev environment? Are your JVM settings the same as those on your target server? What exactly do you mean by low end server in terms of CPU and RAM? Are you able to attach VisualVM that comes with the Sun JDK? This will quickly give you some clues as whether the process is limited by CPU or memory. You can also add a simple filter before the GWT servlet to give you a very coarse request timing - you can at least then rule out latencies and bandwidth to your server. How large are your serialized objects prior to compression? I think you can quickly test this by disabling gzip compression in FireFox: http://forgetmenotes.blogspot.com/2009/05/how-to-disable-gzip-compression-in.html If the uncompressed size is particularly large then memory and compression time may be the limiting factor.

Re: GWT performance
Kristian, Do GMail or the GWT showcase application work well enough for you in your intended browser? If so, then in all likelihood your GWT application will perform adequately. I'm not aware of any reliability issues as such. The only thing that springs to mind is that GWT compiles for specific browsers that it knows about at compile time. Like many other web application technologies, if a new browser comes out then they can break compatibility. Recent examples of this are with IE8 and FF 3.5, however Google have always endeavoured to roll out compiler updates to rectify these issues. Loading times can be a problem and it boils down to a couple of things: 1. I believe IE's JavaScript parser gets disproportionately slower the larger your GWT application is (other browsers do not suffer with this); 2. a compressed GWT application can still be fairly large, say 150k to 200k, which can be an issue if your target audience are all on dial up connections. Remember though that this download is a one-off and the browser will cache that version of the app forever so all subsequent app launches are significantly quicker. Also, GWT 2.0 has a number of things in the pipeline to address these issues (like code splitting). Cheers, Chris.

Re: What are you using for a backend??
Hello, I had better luck finding a host for for my Java stack by looking for a regular VPS rather than looking for dedicated J2EE (or Tomcat) hosting. There are loads out there but I've uses http://rimuhosting.com/order/planselector.jsp for the last 18 months or so and they've been pretty good. As usual, the server/host that you choose depends on your application's needs, expected server load etc. Amazon EC2 could also be worth a look - you can add or remove hardware on the fly which is a great way to handle the Digg effect. However, the cost of their most basic server configuration may be more expensive when compared to a cheap VPS config. For the Java side of things, again there's plenty of choice as to which framework that you use, but I've had very favourable experiences with JBoss Seam (http://seamframework.org/) - there's a section in their reference docs for using GWT plus there is an example in the source code.
