You can use the same container (i.e., tomcat installation) for multiple mid-tiers. The key with the native libraries is to use a classloader to load the jars that is common to both applications. This is typically accomplished by placing the jars that contain the classes that load the system libraries in a in a place where both webapps have a common classloader, then removing the jars (jni) from the deployed app classloader. This has to be done to use the CI viewer, slm collector, and mid-tier from the same container.
