问题 First, I tried to follow the tutorial to deploy my application. After some fiddling and failures, I thought I should run the GWT sample Contacts project and see if that will work on my tomcat with RPC calls. Again, no luck. What I did was create a sample application (when using Eclipse Wizard) compile, run it once on the development server, and see that it works. Then I take the contents of the war folder, zip it, rename it to SampleApp.war, deploy it on the Apache, it unzips. I have a folder

Generate GWT Overlay types from Java objects

三世轮回 提交于 2019-12-11 14:53:54
问题 We're currently using GWT RPC for serialization on a GWT project but we're currently maintaining two sets of objects - the object that we need to convert for the database to retrieve/save and a version of the object that is safe for GWT RPC serialization (no enums/big decimal, etc.). We're spending a lot of effort writing code that merely converts from one format to the other format. In addition it's pretty painful to make any changes to the data model because it has to be changed in two

问题 I have GWT page with rich functionality. I wanted to use this module in different web sites as a widget. But due to limited flexibility of this module I can't change design easily, nor embed this module into different SEO(search engine optimized) pages. If there any CMS or methodology to ease work with GWT? 回答1: Take a look at GaSP: http://code.google.com/p/gasp-web-engine/ It's a CMS that I wrote based on GWT/SQL/PHP. It's pretty flexible. Let me know if you are willing to test it out. It

问题 I have a GWT app which runs pretty much flawlessly in Dev mode with GWT's embedded jetty server. However, I need to move over to using an external jetty server (For various reasons).
