Migration From T0094 to T1222
This subsection describes how to modify an existing configuration of servlets to
conform to Java servlet 2.2 API specifications and the J2EE environment.
There are migration considerations for this product only if the older T0094 SSC is
already installed. If the T0094 is not installed, this section can be ignored.
When modifying an existing T0094 configuration to support T1222:
1. T0094 library and class files must not be in the Java CLASSPATH when the T1222
NSJSP product is in use. The installation of the T1222 NSJSP product will discover
and move any pre-existing T0094 SSC libraries and class files in the default
/usr/tandem/java directories to a backup location. Do not move them back
unless the T1222 NSJSP is uninstalled and the T0094 SSC is re-installed.
2. Pre-existing T0094 servlet.config files cannot be used with the T1222 NSJSP
product. The installation will discover and move any pre-existing T0094 SSC
servlet.config configuration files to a backup location.
3. The T0094 SSC and T1222 NSJSP versions of servlets cannot coexist in the same
iTP Secure WebServer configuration.
4. There is no longer a requirement to map the number of STATIC servlet and HTTPD
servers in the servlet.config file as T1222 NSJSP process instances can be
multi-threaded.
5. Pre-existing T0094 SSC applications should be converted to use a Web
Application Archive (WAR) directory structure. This will require changes to the
T1222 NSJSP servlet.config file to add Filemap directives and to the
iTP_server.xml XML-based configuration file to add servlet contexts.
6. Pre-existing T0094 SSC applications that use property files must be converted to
web applications and have the property file migrated to the web.xml XML-based
configuration file for the converted web application. No change to actual Java
servlet application code is necessary.
