Hi, I am new to xmlBlaster and would appreciate any advice or help on a current problem I am facing.

I am trying to create a simple Java web service that provides one method for publishing a message to the xmlBlaster server. I first created a class by following the HelloWordPublish.java example and it worked fine. I then deploy it as a web service by using axis and tomcat. However, when it is in the web service form, it is not able to establish a connection to the server. By looking a the log produced in the tomcat window (attached below), it is not able to initialise the persistent queue, but I am not sure what is really wrong. Initially I thought it was a classpath problem, and I tried placing xmlBlaster.jar in different places (such as tomcat\common\lib, tomcat\webapps\axis\WEB-INF\lib), but the problem still persists.

BTW, I am using xmlBlaster 1RC2, Tomcat 5.5.4, Axis 1.2 RC2 and JDK 1.5. Thanks!

regards,
Daniel
