Subject Incompatible Class Change error Please help
Date Wed, 16 Jan 2002 20:34:15 GMT
Hello all of you,
                  I have a peculiar problem while
running my web application. This webapplication
communicates with a corba server for which i use the
visibroker ORB jar files.  Now when i place these jar
files in my jakarta-tomcat-4.0.1\common\lib folder the
application works fine. However when i place the jar
files in the 
webapp\WEB-INF\lib  folder the following error crops
up. Please do let me know where i am going wrong
because the specifications mention that the class
loader searches for jar files in the
webapp\WEB-INF\lib folder and it would be better to
place them here for proper deployment.
