Installing PL/Java on MAC

Question

I'm really having trouble installing Pl/Java on Mac, any help would be appreciated.

I'll describe the exact steps I've done in accordance with the README here, but I still get some errors that I cannot resolve.

(1) I've downloaded this version: pljava-i686-pc-linux-gnu-pg9.0-1.4.2

(2) I've located three files in the directory: pljava.jar , deploy.jar , pljava.so

(3) I've put the two .jars inside: /Library/PostgreSQL/9.0/lib

(4) I've put the .so inside: /Library/PostgreSQL/9.0/data

(5) I've modified the postgresql.conf as follows:

dynamic_library_path = '$libdir'
custom_variable_classes = 'pljava'
pljava.classpath = '/Library/PostgreSQL/9.0/lib/pljava.jar’

(6) I've also tried:

dynamic_library_path = '$libdir:/Library/PostgreSQL/9.0/lib/'    (as well as...)
dynamic_library_path = '$libdir:/Library/PostgreSQL/9.0/data/'

(7) I then try to run:

Select sqlj.install_jar('/Software/Libraries/test_trigger.jar', 'samples', false);
Select sqlj.set_classpath(‘public’, ‘samples’);

Although, I keep getting this error:

WARNING:  java.lang.NoSuchMethodError: Method org.postgresql.pljava.internal.Portal._fetch(JZI)I not found

ERROR:  Unable to register native methods

********** Error **********

ERROR: Unable to register native methods

This sounds like an issue is in not loading the right .jar. You mentioned in your comments that you were also having a problem with appropriate environment variables specifying where to load modules. This may in fact be your main issue. It looks like the equivalent environment variable is DYLD_LIBRARY_PATH though you can get more options by looking at man dyld and obviously if you are loading the wrong .so or .jar you will get errors like this.
