The information discussed in this section includes the following:
•
Jar File Considerations on page 7-1
•
Configuration File Considerations on page 7-1
•
Web Application Considerations on page 7-4
•
Changes from Servlet 2.2 to Servlet 2.3 on page 7-4
Directory Structure
The NSJSP 2.0 container is based on Tomcat 4.0.3 (or later) source code, hence the
NSJSP 2.0 release package content is different from the previous NSJSP 1.x releases
(see NSJSP Directory Structure on page 2-8 for details).
Jar File Considerations
•
All servlet related jar files are located under
iTPWS_INSTALL_DIR/servlet_jsp sub-directory tree. No jar files are located
in the $JAVA_HOME/jre/lib directory.
•
iTP_Servlet_JSP.jar and ServletJSPConnector.jar files from the
previous version are removed from $JAVA_HOME/jre/lib directory by the
setupjava script.
•
The servlet.jar file is moved from the iTPWS_INSTALL_DIR/servlet_jsp/lib
directory to the iTPWS_INSTALL_DIR/servlet_jsp/common/lib directory
(CLASSPATH in the user's OSS profile needs to be updated with the new path for
the servlet.jar file).
Configuration File Considerations
The three configuration files have changed a lot in the NSJSP 2.0 RVU.
servlet.config File
The servlet.config file has changed a lot in NSJSP 2.0 (for detailed information
see servlet.config on page 3-2). During installation, your existing servlet.config
file is backed up. The servlet.config file will be replaced by the
servlet.config.sample file (default servlet.config file). You will need to
incorporate your specific configuration into the new servlet.config file.
