[Pljava-dev] PL/JAVA on Windows

[Danny Gaethofs]

Dear Thomas,

After stopping the postgresql server and restarting
it, I am no longer able to open the server connection
in pgadminiii. The message I get is:
could not connect to server: Connection refused
(0x0000274D/10061)
Is the server running on host "127.0.0.1" and
accepting TCP/IP connections on port 5432?

When I remove these lines from my postgresql.conf it
works again.

# PLJAVA - 13-05-06

# define "pljava" as a custom variable class. This is
a comma separated
# list of names.
#
custom_variable_classes = 'pljava'

# define the class path that the JVM will use when
loading the
# initial library. Only meaningful for non GJC
installations
#
#old pljava.classpath =
'/home/Tada/pljava/build/pljava.jar'
pljava.classpath =
'C:\ProgramFiles\PostgreSQL\8.0\pljava\pljava.jar'

# Set the size of the prepared statement MRU cache
#
pljava.statement_cache_size = 10

# If true, lingering savepoints will be released on
function exit. If false,
# the will be rolled back
#
pljava.release_lingering_savepoints = true

# Define startup options for the Java VM.
#
pljava.vmoptions = '-Xmx64M'

# Setting debug to true will cause the postgres
process to go
# into a sleep(1) loop on its first call to java. This
is
# only useful if you want to debug the PL/Java
internal C code.
#
pljava.debug = false


I thought installing pljava would be easy?
Has anyone succeeded doing it on windows xp?

regards,
Danny
