IndexedDb
Hello, I did some test with local and session storage with GWT but it's very limited in size. I'd like to use IndexedDb but there's no native API implemented in GWT. I've saw Elemental in GWT 2.5 but it seems to be experimental. Is there a mature project that wrap the IndexedDb API in GWT ?

Call garbage collector
Hello, I'd like to call the browser's garbage collector. I did some tests with the inspect function in Chome and the button to call the gc but I'd like to do this automatically in my GWT application. I've seen in the JRE emulation reference that the System.gc() method was emulated, but after calling it in my GWT code nothing happened. Is there a way to call the browser's gc in my GWT code ?

Re: Massive increase in compile time with GWT 2.3
Hello, In fact I have exactly the same problem than Dennis. We migrate our application from GWT 2.0 to 2.3 and th ecompilation time has increased about 40%. My problem is not how to optimize the compilation time but why this huge difference between GWT versions. Thank's On 19 mai, 18:30, Hilco Wijbenga hilco.wijbe...@gmail.com wrote: On 19 May 2011 00:37, googelybear googelyb...@gmail.com wrote: This build I am trying to optimize is compiled on our build server by the continuous integration tool (hudson in our case triggered after every commit). It is mainly used to run unit tests and for general testing by the developers to get instant feedback (well, it used to do that when we started). It is not a production build. But I don't like to take too many things out, e.g. take out browsers then you can no longer test it on different browsers and your feedback cycle - the timeuntil you notice something doesn't work after you implemented it - gets longer). For the production build then it is absolutely OK to take longer. In general, I don't think it is a good idea to have one build for (many) different purposes. For unit tests you don't need all browsers so pick one and stick with it. In fact, for unit tests you don't need any browser. :-) Your unit test build can and should be very fast. This should be the most stripped down version you can think of. Mind you, it would be even better if you broke up your app into separate modules so that all the unit testing is done in the small, fast module builds. The second build would be for integration testing. For your automated integration testing you don't need more than one browser either. (Unless, of course, you have a very advanced setup testing multiple browsers.) Run this build once or twice a day at a specifictime(say lunchtimeand dinnertime). (The specifictimeis so that people know about it and can try to make sure their change is (or is not) included.) If the automated integration test build is successful then kick off the full build for all browsers. This need only happen once a day or even once a week. This build is then used for manual testing. It should be auto deployed to some QA/test environment. Most (test/QA) people don't like working with a moving target (for obvious reasons), hence the build once a week suggestion. Then, if QA says this build is good, promote it to production; no need for another build.

GWT 2.0 spring hibernate gilead
Hello, I'm using GWT 2.0, Spring, Hibernate and Gilead for some time now. Gilead allow me to use the DTO pattern and give me the availability to update my DTO's directly. But my problem is that I have a big apps and that the merge and clone are very expensive in cpu and in time. For now with GWT 2.0 could I use directly the entity bean from Hibernate (the lazyinitializationexception is not a preoblem for me) ? I know that Hibernate has his own List implementation could I have some problems with that ?

Re: Profiling memory usage
In fact my problem is not due to the size of the js generated (even if it's quite big). I tried the developer tool from chrome but it's that when I do a head snapshot the result is unreadable. Do you mean that if I compile with the -pretty option, the snapshot will be readable ? Could it have a link betwwen the size of the js file and the memory took by the browser ?
