If you can crash a JVM (Dr. Watson under NT, core dump under Unix) with a Java
program -- servlet, JSP page, applet, or application doesn't matter -- then there
are three possible culprits:
First to be clear I didn't intent to start the classical OS war, just facts : my company does a pretty nice business in the intranet market where NT is the de facto standard (been used with Micro$oft software or Lotus software).
And I'm trying to get our developers to show interest for Java technologies.
Until now I succeeded but this JSP weakness makes me wonder....
* Faulty JVM implementation
I use SUN JDK 1.2.2
* Faulty native libraries (if you are using them) such as a type two JDBC driver
I use for my tests a 100% java database and JDBC driver (InstantDB)
* Faulty OS
Well :-))
But the point is that NT does exist nevertheless what you/we/I can think about it. And there is a large market share in the intranet stuff for the NT OS
I'd suggest focusing on one or more of these areas. The fact that you're seeing
these problems under JSP is coincidental -- they've always been possible (unless
you recently changed one of the three variables above), but didn't get triggered
until whatever the JSP pages are doing under the scenes started getting executed.
I'm not sure of that at all. For example import a java class (for example <%@ page language="java" import="java.sql.*,DBConnectionManager" %>), then compile the jsp (call the jsp to have the jspengine compile the code).
Move the java class elsewhere : result JVM crash, Dr Watson and co....
I mean in this case its normal that the jspengine crashes, perhaps normal that the whole webserver crashes, but crashing the OS...
If you stop the server, delete all the produced code (in the work directory) then start the server, you get an error but not a general crash.
So I suppose that when something really strange appears for a code that has been previously compiled without problem, under NT, the jspengine becomes crazy, and dangerous
