>I have built the lastest RHQ version. the 4.0.0 - snapshot version.
If this means you took the current master branch from git and built it, you are using the current in-development codebase right now. At this moment in time, our UI is in a major state of flux - we are converting over to GWT (from struts/JSF). Therefore, do not expect to get a functional build like you have with the currently available release builds - build from master if you are developing RHQ and want to contribute fixes/enhancements to it (don't build it if you just want to deploy and use RHQ - grab a release build if you want to do that).
Alot of the graphs/monitoring pages are not finished yet. In fact, we are contemplating which GWT graph component we want to use (i.e. we probably want to replace the graphing solution we have today in master) - see http://rhq-project.org/display/RHQ/Design-NewChartingLib
Thanks for your ever so prompt replies
Is there any official date of Jopr4.0.0 release ?
There is no official date yet for RHQ 4.0.0 (note that the brand "Jopr" is being superceded 'back' to RHQ - Jopr has been rolled upstream into RHQ). Sometime late this year is the best we can offer at this point in time.
