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

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'.

java -version ?

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

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 (fnasser@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!

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 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. > [remainder snipped] > -- Jim Seymour | Spammers sue anti-spammers: jseymour@LinxNet.com | http://www.LinxNet.com/misc/spam/slapp.php http://jimsun.LinxNet.com | Please donate to the SpamCon Legal Fund: | http://www.spamcon.org/legalfund/
