[Pljava-dev] Error message java.lang.ClassNotFoundException: 'pljavatriggers.TestTrigger1'

Dear *,

I am trying to compose a Trigger using pljava and I am getting the error
message:
java.lang.ClassNotFoundException: 'pljavatriggers.TestTrigger1'

Here are the steps I followed:

1) I created the TestTrigger1.java (belongs to package pljavatriggers..)
file and created testtrigger.jar in the directory
d:\pljavatriggers.
2) Then I created the trigger function with the following code

CREATE OR REPLACE FUNCTION sqlj.testfunction()
RETURNS "trigger" AS
$BODY$ 'pljavatriggers.TestTrigger1.execCommandLine'$BODY$
LANGUAGE 'javau' VOLATILE;
ALTER FUNCTION sqlj.testfunction() OWNER TO xristis;
GRANT EXECUTE ON FUNCTION sqlj.testfunction() TO xristis;
GRANT EXECUTE ON FUNCTION sqlj.testfunction() TO public;

3) The trigger was created

CREATE TRIGGER test_trigger
AFTER INSERT OR UPDATE
ON sqlj."Doctor"
FOR EACH STATEMENT
EXECUTE PROCEDURE sqlj.testfunction();

4) The jar was installed and it was added to classpath... SELECT
sqlj.install_jar('file:D:\\pljavatriggers\\testtrigger.jar','testtrigger',tr
ue);
SELECT sqlj.set_classpath('sqlj','testtrigger');

With no error messages...

When I try to execute an SQL Update query I get the error message
java.lang.ClassNotFoundException: 'pljavatriggers.TestTrigger1' as mentioned
before

Can anyone tell me what I am missing ??

Thanx,
Manos
