[Pljava-dev] unable to invoke sample pljava program.

Dear Dev Team,

i am beginner for pljava. i am struggling a lot to invoke a simple pljava
program.

i have done the following things successfully.

*1.Sample java class which is having a static method as follows*
*
*
public static String hello(String hello){
return hello;
}

*2.Installed the jar *

SELECT sqlj.install_jar('file:///D:/Program
Files/PostgreSQL/9.1/lib/PLJAVA_Custom.jar', 'PLJAVA_Custom', true);

jar is loaded into jar_repository table of sqlj schema and also classes are
identified and loaded into jar_entry table of sqlj Schema,
*
*
*3. Set the Classpath successfully*
*
*
*SELECT sqlj.set_classpath('public', 'PLJAVA_Custom');*
*
*
*4. I have created a sample function as follows*
*
*
CREATE OR REPLACE FUNCTION handle_data2(character varying)
RETURNS character varying AS
'pljavaone.DataHandler.hello'
LANGUAGE java VOLATILE

*when i am executing its returning me the following error ERROR:
java.lang.ClassNotFoundException: pljavaone.DataHandler. *

Thanks in advance.

You need to add the parameter type to the java signature in the definition.
