I deployed the three Flex Data Services 2 WAR files to Websphere Application Server Community Edition (via the web admin console), but when I go to any of the sample applications, I get the following error page:
Errors, warnings or exceptions were found while compiling /dataservice/notes/notes.mxml. Visit the online Flex documentation or API reference for further information.
What JRE version are you using? I received NoSuchMethodErrors when trying to compile flex apps when I first started. The JRE does not recognize the XPath Method. Turned out that the JRE that I was using was the problem. I think I finally settled on using 1.4.2_12 (I had problems with some of the newest runtimes, and other problems if I go back too far) and haven't had problems since. Might be something to try.
