the following is my suggestion :-)
* when you compile your Servlet code, LinkBean need to be in CLASSPATH
* when you run your Servlet code, LinkBean need to be in:
if(LinkBean is a unpacked class){
- WEB-INF/classes(together will your Servlet class)
- $CATALINA_HOME/classes
- $CATALINA_HOME/common/classes
}
else if(LinkBean is in a packed jar){
- WEB-INF/lib
- $CATALINA_HOME/lib
- $CATALINA_HOME/common/lib
}
