Ernst, Before you attempt to do what you suggest, I would suggest you first do some analysis of your environment. There are some things that you need to be aware of. The first thing you need to do is determine if there is a performance problem. What are your performance goals? What makes you think that JBoss is the problem? How did you test this? Can any performance problems be solved by throwing more hardware at the problem? Are there alternative J2EE app servers that will meet your performance goals?
Also, keep in mind that the speed of JBoss is determined more by I/O (disk, network, database, etc.) and context switching speed of the underlying OS than by the JVM (Java Virtual Machine). Since you claim to be a Java newby, I have to point out some things about Java you probably didn't know: I assume that the JVM on the AS400 has a JIT (Just In Time compiler). Knowing IBM, this JIT will be of excellent quality. My (pretty extensive) experience with long running systems like JBoss is that running the java program with a JIT will be close to the speed or sometimes *faster* than running a native version (java compiled into native code). (At least Sun's Hotspot JIT in server mode outperforms anything I've tried, including optimized C++ code, when it comes to memory allocation/deallocation.) In short, don't underestimate the power of java and the JVM. :-) So, my advise is: don't even think about doing a project like this unless you know absolutely need to. Evalutate the cost of your effort compared to the performance gain that you may or may not get. Ernst Bekker wrote: >I unzipped 2.4.1 on our as400 v5r1 at work.
