Cant Call Stored Java Method Oracle 8I

Question

I have some java code which I have compiled under the package schedsrv which I have loaded in the server with the loadjava facility
I created the procedure link using
create procedure as java using
schedsrv.ClassName.Procedure(java.lang.String, etc
I call the function and the server says no method name exists
for schedsrv/Classname where is the problem
I loaded the java from a .JAR and the classes were in a subdirectory called schedsrv and are in the .jar

Answer 1

This is the wrapper
create or replace procedure CreateScheduleEmp(EMP IN NUMBER, DID IN DATE, ENDD IN DATE) authid definer as language java name 'CreateScheds.processEmployee(java.lang.String,java.SQL.Date,java.SQL.Date)';
Called by
Execute CreateScjeduleEmp(1547,'00-JAN-00','07-JAN-00');
this is the class.
public class CreateScheds {
public CreateScheds() {}
public static void processEmployee(String emp, Date did, Date end) {
try {
CreateSchedules shed = new CreateSchedules();
shed.processEmployee( emp, did, end );
catch ( SQLException e ) {
System.err.println(e.getMessage());
it the class it creates and calls has an abstract base and is extended and completed in CreateSchedule which was written using
SQLJ.
The error I am getting says it can't find the
processEmployee method.
I tried it in a package which failed as well.
This is the class it calls
