I have commented out the invoker in web.xml for tomcat as suggested and
changed the mapping relative to the webapp root, however I still find the
same problem
2003-03-10 16:23:11 StandardContext[/GenDBconn]: Mapping
contextPath='/GenDBconn' with requestURI='/GenDBconn/serv
let/Controller' and relativeURI='/servlet/Controller'
2003-03-10 16:23:11 StandardContext[/GenDBconn]: Trying exact match
2003-03-10 16:23:11 StandardContext[/GenDBconn]: Mapped to servlet
'Controller' with servlet path '/servlet/Contr
oller' and path info 'null' and update=true
2003-03-10 16:23:11 StandardWrapper[/GenDBconn:Controller]: Marking
servlet Controller as unavailable
2003-03-10 16:23:11 StandardWrapperValve[Controller]: Allocate exception
for servlet Controller
javax.servlet.ServletException: Error instantiating servlet class
edu.berkeley.library.GenDBServlets.GenDBControll
er
since my application is not under ../webapps, I have the following in the
server.xml file:
<!-- GenDB -->
<Context path="/GenDBconn" docBase="/data/_n/GenDBconn" debug="4"
reloadable="true" crossContext="true">
<Logger className="org.apache.catalina.logger.FileLogger"
verbosity="4"
prefix="localhost_GenDBconn_log." suffix=".txt"
timestamp="true"/>
</Context>
thank you,
Giulia
