Re: [Opaltoolkit-users] Installation problems

[Sriram K. <sr...@sd...>]

Hi Daniel,

It appears as if none of the Opal jars can be found. Did you restart  
Tomcat after Opal installation? At this point, Opal can't be hot- 
deployed, and you will have to restart your Tomcat after installation.  
If you have indeed restarted, please check your CATALINA_HOME/webapps/ 
opal2/WEB-INF/lib to see if all the Opal jars are present. If they  
aren't, something went wrong with the installation.

A list of Opal services is provided by Axis, e.g. http://ws.nbcr.net/opal2/services 
. Does that not work for you?

Cheers,
Sriram
