If you don't want module B to inherit module A, then create a new module that sits alongside A that includes AbcDTO and have B inherit that. Paul On 29/02/12 21:34, Deepak Singh wrote: Hi All, I have the following scenario. In GWT application, i have two seperate modules, not inherited one f

Re: GWT Compiler - java.io.IOException: Too many open files

When building a ClientBundle with images, the compiler holds all the source image files open at the same time, even if you never refer to the image in your code. This can be a problem if you've got a lot of images in the bundle interface. I think this is probably a bug, and I thought there was

This depends entirely on what server-side technology you choose to use. It's not really a GWT thing. Paul On 07/02/12 03:15, Edwardxiong wrote: My website is a pure GWT site. It need members to login with their account and password. To prevent multiple users login with one same account, I need

Re: How to handel Day Light Saving in GWT2.0

Timezones are a pain in javascript because it just doesn't do them. If you have a javascript Date on the client, it will always display in the client's timezone. If you want to apply timezone offsets, you must do that on the server. You can't then simply transfer the resulting java.util.Date vi

Re: Initializing Hibernate

This really depends on how you set up your server, but you will probably have a servlet that is used for communication with your GWT client. So you can put your initialization code in your servlet's init() method. HTH Paul On 24/12/11 17:16, Blake wrote: Greetings, I want to use Hibernate wi

You're correct. Best practice for choice of return type in an RPC interface is the exact opposite from what you would normally use in Java. That is, you should be as specific as possible to avoid forcing GWT having to generate serialization code for every implementation of Set or List etc. Pau

It's not a bug. Or at least, it's not a bug in GWT. This is the way CSS works with javascript...whenever you set styles in javascript you must use camel case, and in a css file you use hyphens. GWT was trying to stop you from making a mistake by pointing out that you had a hyphen in your css wh
