[Pljava-dev] Manifest for examples.jar

[Eric E]

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):

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

Thanks,
