New version of world's first (and only) open source graphical Java workflow editor fully according to WfMC specifications is
released.

It can be used to edit / view every XPDL file which conforms to WfMC specifications.

The new version brings completely new architecture and L&F with a lot of advanced features.

There are several open source and commercial workflow engines working with JaWE, like Enhydra Shark , WfmOpen, OBE and OfBiz !

Enhydra JaWE has already become the worldwide de-facto standard to edit XPDL files. It participated in WfMC interoperability demo
where it was used to handle XPDLs from Fujitsu, TIBCO and Enhydra Shark engine.

The project is hosted on ObjectWeb, it has a large community, and is highly rated on ObjectWeb.

For the professional users, commercial version called Together Workflow Editor is now available.
You can test it by downloading demo version here.

Hi all,

We have an exception that we are working over it more than 2 weeks in order to resolve it.
java.lang.ClassNotFoundException: org.enhydra.realm.DODSRealm
We tried all the ways possible but the result is the same.

Everything is where they are supposed to be. Nothing missing. All the configurations are correct(tested with other computers). The same configuration was tested in two other computers and sytem runs in them without problems(EVERYthing is the same jdk,tomcat,all the configs,directories...etc..).

But in only one of our computers shark can not run. We dont know why, and it isvery important forour development process... We always get the same exception. We are faced with a very special case that we can't/couldn't resolve.

We get this exception when we try to start shark engine within Tomcat container. Tomcat can't start(cause of exception) and we get this exception

Any help will be appreciated...
It is very urgent for us.
Thanks in advance...


Excaption that we get:
