IAS JServ (servlet) configuration problem

Question

I hava a very simple servlet that calls request.getSession() method. It runs OK from JDeveloper environment, but on iAS I get an Internal Server Error.
error_log shows:
java.lang.NoSuchMethodError: javax.servlet.http.HttpSession javax.servlet.http.HttpServletRequest.getSession()
void org.apache.jserv.JServConnection.run()
void java.lang.Thread.run()
My jserv.properties file has
# Oracle Servlet
wrapper.classpath=c:\oracle\ias\jsp\lib\servlet22.jar
What am I missing?
Thanks a lot...

Hi TechnoSam,
The problem here is, you are not following the correct directory structure.
consider your webapplication is placed in a directory called $TOMCAT_HOME$/webapps/TechnoSamAPP
by default the default context will be $TOMCAT_HOME$/webapps/ROOT
If you want to have your own context, create a directory in webapps like
if you have created a directory Example: TechnoSamAPP
it will become a Web Application Context and which expects a <Context> entry in server.xml file.
You can copy all your files in to this directory by follwoing the directory structure mentioned in the servlet spec SRV.9.5.
You need to place all static resources(*.html, *.jpg, *.gif, *.js, *.css) in this context root directory
i.e.,
/webapps/TechnoSamAPP
� The /webapps/TechnoSamAPP/WEB-INF/web.xml deployment descriptor.
� The /webapps/TechnoSamAPP/WEB-INF/classes/ directory for servlet and utility classes. The classes in this directory must be available to the application class loader.
� The /webapps/TechnoSamAPP/WEB-INF/lib/*.jar area for Java ARchive files. These files contain
servlets, beans, and other utility classes useful to the web application. The web application class loader must be able to load classes from any of these archive files.
The web application classloader must load classes from the WEB-INF/ classes
directory first, and then from library JARs in the WEB-INF/lib directory.
Hence place all your static files (which are accessible for public) into the Context's root directory rather than Tomcat/bin.
Place all servlets in to /WEB_INF/classes which will be accessed by Servlet Container.
