Hi Thomas,
I am building PL/Java from the source along with some modifications
I'm working on. The build succeeds, and I was able to deploy pljava.so
and pljava.jar under JDK 1.5.07. In order to overcome the zlib issue, I
switched to JDK 1.6b2, because I think I've read that Java 6 can read
binaries compiled with Java 5 without problems. When I try to build
using Java 6, the compile complains about a bunch of unimplemented
methods in the JDBC interface definitions.
I then attempted to run
sqlj.install_jar('file:///......./examples.jar', 'samples', true);
It starts, and I can actually remotely connect to the JVM, but the
function dies with the exception:
ERROR: java.sql.SQLException: No such class:
org.postgresql.pljava.example.ComplexTuple
When I unzip the file, the manifest is empty, which makes sense, because
the manifest in the build tree is also empty. However, upon unzipping
examples.jar, the class is present inside of it, and less examples.jar
returns (presumably the zip manifest):
Archive: ./examples.jar

So the class is actually there. Any thoughts on why sql_install_jar
can't find it?
Thanks,
Eric

Yes, I've seen that. Apparently the latest 1.6 introduces the JDBC 4
standard. It in turn, adds some new methods. I'll look into that with
the intention to create dummy implementations that throw unsupported
feature exceptions for now. The actual JDBC 4 will have to wait a while
longer.

This is likely to be a consequence of earlier compilation errors.

It's there, but it's broken.
I suggest you revert to Java 1.5 for now and rebuild your postgresql
using 'configure --without-zlib' to avoid the zlib issue.
