Yup. Seems some form of jdk-1.2 works for me. But my default
/usr/bin/javac (on an old RH5.2 system), something called "pizza",
does not.

Do you still need them? I can send what I built, but I'm pretty sure
that Peter Mount has a fresh package built and available on some web
site of his...

I don't do Java -- and the RPM's have historically packaged the .jar files as pulled verbatim from retep.org.uk. I haven't distributed RC2 RPM's yet for partially that reason -- the other part is the lack of an RC2-tested alpha patch. NOTE: I have gotten good response and patches to the RPM's from a number of people this go around -- and it is ENCOURAGING! -- Lamar Owen WGCR Internet Radio 1 Peter 4:11

I was not setting the CLASSPATH to be the full file path. I was setting it just to the directory, which was my fault. Peter's FAQ for jdbc helped me get it working. Peter E. sent me a jar file, but it used postgresql as the domain unstead of org.postgresql, so it seems that is the 6.5.2 version too. Peter's web site does not have the 7.0 jar file there yet. However, it seems kaffe can't compile self-referencing java files. I don't know enough about java to know that is a problem or not. I did get it working well enough to get my java book example working. -- Bruce Momjian | http://www.op.net/~candle pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

"I don't do Java" can change fairly easily; just pick up the java
tarball from blackdown.org or sun.com, untar it into /usr/local, then
set your path via
set path=(/usr/local/jdk-xxx $path)
Go into src/interfaces/jdbc and type
make jdbc2
then grab the jar file(s).
otoh, how close are you Peter (hope you see this; I've blown away
enough email to have lost your address) to posting a built jar file or
whatever is usually provided? Should we post this somewhere on
postgresql.org to help out? Should I post my recently built stuff?

Have not tried with 7.0, but recent versions of Kaffe were definitely able to compile the JDBC code that came with 6.5.3, but only after modifying the version check in the makeVersion.java file in src/interfaces/jdbc (and perhaps elsewhere where a versioon check occurs). The code checks for the java version string and rejects everything that doesn't start with either 1.1 or 1.2. The problem was that Kaffe reports its own version, e.g. 1.02, rather than the corresponding JDK version.

Ah, found Peter's e-mail address in an obvious place (the jdbc source
tree).
Another question for Peter: would it be possible to update the README
file in the source tree, and other ancillary files? I know you've been
very busy, but even a brief fixup to adjust dates and version numbers
would be helpful for 7.0.

It does compile under kaffe 1.05, but the mutually dependent java files cause a compile error. Seems 6.5.3 had the same problem, so I am not sure why it would have worked then. -- Bruce Momjian | http://www.op.net/~candle pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

In fact, now that I think of it, this is most likely what I did. Even then, with some version of the driver I had to patch a runtime version check to make it behave as if Kaffe was a 1.1 JVM. It is true that Kaffe has a number of problems. Nevertheless, given that it is licensed under the GPL some people prefer it over the alternatives even if it has some drawbacks.

I have contacted them about the problem to see if they can help. This is clearly a kaffe-related problem, and not a problem with our jdbc, which is good news. -- Bruce Momjian | http://www.op.net/~candle pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026
