[Opaltoolkit-users] Installation problems

[Daniel B. <Ble...@ma...>]

Hi,

  We¹re using Taverna ( http://www.taverna.org.uk/) as our workflow engine,
and would like to expose some of our command line apps.  I was able to
connect to the getVersion service.  When I tried to install the date
service, I get this error (in the tomcat log):

Oct 4, 2010 11:10:06 AM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [AxisServlet] in context with path
[/opal2] threw exce
ption [Servlet execution threw an exception] with root cause
java.lang.NoClassDefFoundError: Could not initialize class
edu.sdsc.nbcr.opal.AppServiceImpl
    at java.lang.Class.forName0(Native Method)
    at java.lang.Class.forName(Class.java:247)
<snip>

And the List page doesn¹t show any services.

I also can¹t connect to the dashboard:

java.lang.NoClassDefFoundError: Could not initialize class
edu.sdsc.nbcr.opal.state.HibernateUtil
 edu.sdsc.nbcr.opal.dashboard.persistence.DBManager.<init>(DBManager.java:73
)
 edu.sdsc.nbcr.opal.dashboard.servlet.OpalInfoServlet.init(OpalInfoServlet.j
ava:109)
 org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:10
8)


Any help?

Also: is there some way to publish all the services on one URL so Taverna
will grab all of them rather than one at a time?

Thanks,
-dan
