Looking for help building 'rhdb-explain' Visual Explain tool

[Jeff Boes]

I'm hoping there's someone here with experience in building the Visual
Explain tool from Red Hat. I downloaded it and the J2 SDK, but when I
attempt to follow the build instructions, I get messages like:

error: Type `JTableHeader' not found in the declaration of the local
variable `header'.
[javac] JTableHeader header = null;

To me, this indicates that the SDK isn't installed (properly). But I
admit I'm pretty much a Java know-nothin'.

I remember when computers were frustrating because they *did* exactly what
you told them to. That actually seems sort of quaint now.

Jeff, have tou set the environment variable JAVA_HOME to where your SDK
is installed?

Please try:

echo $JAVA_HOME

and

which javac

It was undefined ... I set it to "/usr/java/j2sdk1.4.2_04".

and

which javac

Nothing found in my path. However, with or without the above change, the
build process seems to find "javac". I still get:

Yes, the javac Ant task probably looks for it in a few places.

Try doing this:

export PATH=/usr/java/j2sdk1.4.2_04/bin:$PATH

and do it again.

Which OS and version are you doing this on?

Thanks to some patient hand-holding by Fernando Nasser
(fn*****@redhat.com), I managed to make this work.

Details, for those following my bread-crumb trail:

My OS is Whitebox 3.0. I installed the Java SDK RPM, but until I did this:

$ export CLASSPATH=/usr/java/j2sdk1.4.2_04/jre/lib/rt.jar

I couldn't get "ant" to build the package.

After I built it, some further messing around was necessary to discover
that I needed the JDBC, and that I needed to edit CLASSPATH some more. I
ended up with this incantation:
$ export
CLASSPATH=/usr/java/j2sdk1.4.2_04/jre/lib/rt.jar:/home/jboes/downloads/pg74.213.jdbc3.jar:.

(Don't miss the ":." at the end of that line!) Then I could "cd" into
the "build" directory and run the tool with the command line as
specified in the README:
$ /usr/java/j2sdk1.4.2_04/bin/java com.redhat.rhdb.vise.Vise

So, up and running at last. I'm sure there's an easier way to configure
this, but being a Java-on-Linux neophyte, this was as much as I was
willing to learn about the process just to evaluate the tool!

Dazed ...

I don't know about the "Whitebox" (whatever that is) OS, but on my
Sparc Solaris boxes, anything placed in $JAVA_HOME/jre/lib/ext/ is
automatically added to CLASSPATH when a Java app is started-up.

After I built it, some further messing around was necessary to discover
that I needed the JDBC, and that I needed to edit CLASSPATH some more. I
ended up with this incantation:
$ export
CLASSPATH=/usr/java/j2sdk1.4.2_04/jre/lib/rt.jar:/home/jboes/downloads/pg74.213.jdbc3.jar:.
I decided to build on how Java works on my Sun boxes, by mimicking its
"default CLASSPATH add-ons" directory in /usr/local. Then I wrote a
"java_profile" script that automatically adds any jarfile it finds
there into the CLASSPATH environment variable. It gets run by, say,
/etc/profile, so all users get it.
