I just went through setting up an Apache Tomcat v6.0.16 application
server, using Sun Java6 update 5. Just to use a report server called
"i-Net Crystal Clear Plus Report Server"

I also had to figure out why the MySQL Connector J v5.0.16 was screwing
things up. I also had to figure out why _*all*_ the "jars" in a "lib"
directory would not properly load. They were proper jar files (similar
to tar files with manifests in them) but a "standalone listener" would
not run dynamically load them, even though the Java Dynamic Updateable
Loader SAW and cataloged them... it just would not load them all. even
-classpath $WEB-INFDIR/lib wouldn't load them/

All in all, tomcat6 loaded everything just fine after I reverted back to
using the v3.1.2 MySQL Connector J. But I ended up doing a small shell
script to construct a "-classpath"

Its pretty ugly IMO, but it works and my bossman tried something in Perl
and it kept bombing during the loading.

-------------------------------------

I am actually running this remote interface out of the Tomcat6 deployed
webapps area, mainly because it was told to me it *(W|C)OULD NOT* work
EVER, PERIOD. By Tech Support from the company, as they said logging
wouldn't work.

Only thing I had to do was create a logging fifo so that both tomcat6
and the standalone remote interface could log to the same file without
trouncing each others access to the log file. Then create a "cat"
process to log to the real file. And of course... check for the fifo and
make sure the cat process is running, making a symlink made by doing:
"ln -s /bin/cat /bin/ccr79cat" makes things much simpler.

The remote interface is the "API" interface for the Report server, think
of it JUST like the Tomcat6 report server without the Web-Interface to
post stuff.

Oh, the one thing *I* do need to finger out, is whether or not I have
made a proper "WAR" or Web ARchive and in the proper context so that
Tomcat6 can auto deploy it.
