Problem using MessageContext.getCurrentContext() (java.lang.NoClassDefFoundError)

[Abhishek Agrawal <aa...@vt.edu>]

I am trying publish a webservice that can be configured at deploy time. For 
this i add the following line to my deploy.wsdd

<parameter name="configFile" 
value="/home/aagrawal/pathport/java/tomcat-4.0.3/webapps/axis/query/query/ws/config.properties" 
/>

The config.properties file has some information which i try to get in the 
constructor of my web service. Here is i uses the following code in the 
constructor of the webservice. 

    MessageContext m = org.apache.axis.MessageContext.getCurrentContext();
    SOAPService s = m.getService();
    String filename = (String) s.getOption("ConfigFile");

When i run the webservice client i get "Internal server exception"

Looking at the log file is see the following exception on the line of the 
constructor.
MessageContext m = org.apache.axis.MessageContext.getCurrentContext();
