Stored Procedure call using JDBC is failing

Hi,

Stored procedure execution using JDBC is failing.

JDBC driver build number: 42.2.5
Server version: PostgreSQL 11


Exact error message and stacktrace:
org.postgresql.util.PSQLException: ERROR: testproc(integer, integer, character varying) is a procedure
  Hint: To call a procedure, use CALL.
  Position: 15

What you were doing, ideally in code form: 


CREATE OR REPLACE PROCEDURE public.testproc(
 batchcount bigint DEFAULT 100000,
 INOUT outcount bigint DEFAULT 0,
 INOUT errormsg character varying  DEFAULT ' ')    
..............................

Java code:

String commandText = "{ call testproc(?,?,?) }";
CallableStatement stmt = conn.prepareCall(commandText);

stmt.setInt(1, new Integer("10000"));
stmt.setInt(2, new Integer("0"));
stmt.setString(3, new String("Start"));
stmt.registerOutParameter(2, Types.INTEGER);
stmt.registerOutParameter(3, Types.VARCHAR);

		    
stmt.execute();
