RE: [ANN] The Reference Scanner and Jakarta Tomcat - Heap Profiling, Memory Leaks
Hi,
Come on people. Tomcat5 is built with MX4J because its license is now
OK (and I modified the NOTICE file that ships with tomcat5 accordingly).
If you want to recompile things to need to make sure your classpath is
setup accordingly: either figure it out from the tomcat build file or
nag Senor Baumgaertel to add instructions to his documents. It's just
like the HttpScanner thing you mentioned: he didn't document the import
statement for that class, but it's fairly obvious.

I tried that, but when trying to run tomcat I got:

Implementation) and copy the JAR containing the API and
implementation of the JMX specification to:
${catalina.home}/bin/jmx.jar
...which confuses me, because jmx.jar is still where it always was.
Using the bootstrap.jar that came with tomcat works fine.
If you use the latest version of Tomcat5, you'll find that this is
not
an issue. Download Tomcat-5.0.24. The implementation of JMX that
said
version of Tomcat comes with is MX4J which is open source so there is
no
problem anymore.

I am using 5.0.24, and jmx.jar is there. Tomcat works if I use the
Bootstrap.class that comes with it, but if I recompile Bootstrap.class
per the instructions on http://jb2works.com/refscan/tomcatfull.html it
suddenly gives me that error message.
I can post the jar file if you think that will help.

No, I can't help you with recompile questions. I just know that previous
versions of Tomcat required you to provide the JMX jar since they had been
shipping the Sun implementation, and probably in violation of the license. For
this reason, they removed jmx.jar, but they have added it back now that they use
the MX4J implementation. I can't remember if this affected Tomcat-5.0.19 or
alpha releases in between 5.0.19 and 5.0.24. All I can say is that, out of the
box, 5.0.24 should work just fine.

BTW in your instructions you say to add:

com.jb2works.reference.HttpScanner.start( startupInstance ); // -- !!
