I've got a team at another site at $JOB asking me about the state of
pljava on centos 6.x 64bit, postgres 9.whatever and which java to use...
what IS the state of this project? last time I tried to package
pljava for deployment, I found it annoyingly finicky and opaque to get
working. most of the documentation seems quite old, and is talking
about truly ancient java 1.4, 1.5 releases, postgres 8.0 and so forth.
Ideally, I'd like to use the RHEL6 provided openjdk 1.7 with pgdg
provided postgres 9.3, all 64bit. I'd really rather not have to compile
stuff, as this is being deployed overseas and supporting them is a big
enough pain with standard components, never mind homebrew stuff.

As far as I can tell from the mailing list and repository activity,
essentially abandoned at this point.
As someone who likes Java I'd like to see PL/Java be a more viable
option than it presently is, despite the mismatch between Java's
thread-based heavyweight-startup shared-everything-by-default model and
PostgreSQL's lightweight-process-based shared-nothing-by-default model.
PL/Java is less useful than it would be on a thread-based RDBMS because
you must use remoting to communicate between different PostgreSQL
connections within the same PostgreSQL instance, but it remains a
powerful tool ... just one that nobody seems to really be doing much
with at the moment.
PL/Java needs some remediation work in things like the logging
integration and its JDBC interface over SPI, so making it usable is not
just a matter of updating it for the latest JDK and PostgreSQL.
Like so many things I don't think many prospective users are willing to
actively contribute to its maintenance, and few people will work on JNI
code in their spare time. I have enough trouble getting people to
contribute to PgJDBC and finding time to work on that myself.
If you're interested in getting PL/Java rolling again it might be worth
speaking to someone on
http://www.postgresql.org/support/professional_support/
about that.
Otherwise you could do what everyone else seems to when they see
PL/Java's current state and just use an external JDK.

Well, that hasn't been my experience. I haven't built lately but one of my devs did for our project. I just pointed him at the build and it worked for him. I didn't even have to step in and help him over hurdles.
As to development, it's pretty fricking stable, so there's not a huge passel of work that needs to be constantly done. You can chalk this up to the way java had designed jni. Moving to a different version of Java requires nothing to change.
As to how it works in production, I got to say I haven't had any problems. And I'm running openjpa in my stored procedures. It's an extreme case but it works like a charm.
There's still work to do on supporting the modern jdbc driver and all the Postgres stuff. But that's work that can be done at our leisure. And it's only if you need it.
Anyways, your mileage may vary, of course. But I don't think that one should deduce that this is a useless project just because there's not a whole lotta Dev work going on. Thanks to the jni stability of java, there really isn't all that much that needs to be done.
At least for our project, pl/Java works, and works well.

apologies for being so noobish here, but i'm running on fumes, and this
stuff is rather far out of my comfort zone.... I generally avoid java
stuff.
so I'm looking at the github.com/tada/pljava stuff, and its been so long
since i've touched pljava, I can't even figure out how I should build
it. the 'Building' instructions aren't even remotely 'instructions',
they are a few random notes.
are there no current binaries, with a .so for 64bit linux such as
RHEL6/CentOS6 that will work with openjdk 1.6 ?
or, if there are no current binaries for linux, where/how do I download
the current source, is the src-snapshot here
http://pgfoundry.org/frs/?group_id=1000038 the latest? there appear
to be a few source file changes july 2013, and that snapshot is from 2012.
I'm not very familiar with using git, and where I should go to compile
the pieces. I think I remember I need to create two files, the .so for
the postgres and the .jar, plus teh deployer and the test scripts.

As the original creator/author of the code base I'd like to mention that while I have limited time to spend on PL/Java
nowadays, I will help and answer questions about the code if anyone has an interest in improving it. I will also review
and and probably accept patches in the form of pull requests to https://github.com/tada/pljava

ok, I figured out this part, at least...

ok, so I figured out I'm supposed to use Maven.
Hmm, not in any 'sane' CentOS 6 repository, ugh, so I get apache-maven,
put it in /opt, put that in my path, run `mvn --version` and it seems to
be good, ok.
so I go to the pljava root, and run `mvn clean install` (hey, I have no
idea how to do this), and it downloads a bajillion things from
http://repo.maven.apache.org (where is all that going?!? ahhh,
~/.m2/... yeesh), then...

I'm glad to see that you're keeping an eye on things, and was clearly
mistaken in thinking PL/Java abandoned - simply fairly stable/mature,
and not subject to tons of ongoing change and development.
A few tweaks to the docs/makefiles to indicate the most recent tested
versions may not hurt.

and for MORE fun. I tried Sun JDK 1.6, and same thing
wait, the notes/wiki did say something about compiling in JDK 1.6 was
broken, so I installed Sun-err-Oracle JDK 1.5.0_22 64bit, and enabled
that as the default java with alternatives, also set my JAVA_HOME and
PATH accordingly ...
nope. weirder more different errors.

You'll need to set the environment JAVA6_HOME (note the 6) in order for it to compile.

where does `mvn install` put stuff, anyways?? I don't understand maven
at all.
$ find . -name \*.so -o -name \*.jar
./pljava-ant/target/pljava-ant-0.0.2-SNAPSHOT.jar
./pljava-examples/target/pljava-examples-0.0.2-SNAPSHOT.jar
./pljava-api/target/pljava-api-0.0.2-SNAPSHOT.jar

./pljava/target/original-pljava-0.0.2-SNAPSHOT.jar
./pljava/target/pljava-0.0.2-SNAPSHOT.jar
can I assume these are the two files I need?
./pljava-so/target/nar/pljava-so-0.0.2-SNAPSHOT-amd64-Linux-gpp-shared/lib/amd64-Linux-gpp/shared/libpljava-so-0.0.2-SNAPSHOT.so
./pljava/target/pljava-0.0.2-SNAPSHOT.jar
the first one's name and path doesn't make much sense to me.
this documentation
https://github.com/tada/pljava/wiki/Installation-guide is really
inadequate to figure out how to do this.

Since it's not in the README, and only appears:
$ git grep -n JAVA6_HOME
pom.xml:95:
<bootclasspath>${env.JAVA6_HOME}/jre/lib/rt.jar</bootclasspath>
that's unsurprising.
Maybe the README.md could use a few pointers on building?

understatement of the year.
'building' page... https://github.com/tada/pljava/wiki/Building-pl-java
'installing on linux' page,
https://github.com/tada/pljava/wiki/Installing-on-linux-%28or-other-%2Anix%29
ummmmmmm. thats ALL I can find.
