Subject Re: Problems with SAX implementation executing a HiveMind example
Date Wed, 10 Nov 2004 15:56:53 GMT
Thank you Knut,

you are right, our problem was due to the use of ant inside WSAD. We 
have changed the structure of our project to enable its execution from 
WSAD, putting WEB-INF/hivemodule.xml inside the "src" folder. Doing so, 
we enable HiveMind to access "hivemodule.xml" when running from WSAD, 
and accesing its classpath. As we are using JDK 1.3, we have to add the 
SAX parser implementation JARS, but we have tested with JDK 1.4, and 
this is not necessary, as the JRE contains them.

Our example runs now perfectly, but avoiding Ant.
