No procedure/function/signature

Question

I am relatively new at using stored procedures and I have really run up aganst the wall. I am receiving the following error message using the Spring JdbcTemplate. My dev environment is Xubuntu, jdk 1.8.

The stack trace is:

Exception in thread "main" org.springframework.dao.InvalidDataAccessApiUsageException: Unable to determine the correct call signature - no procedure/function/signature for 'PROCONEINPARAMETER'

Code:

SimpleJdbc.java

package test.jdbc;
import java.util.Map;

import org.springframework.context.ApplicationContext;  
import org.springframework.context.support.ClassPathXmlApplicationContext;  
public class SimpleJdbcTest {



    public static void main(String[] args) {  
        ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");  
           StringDao dao=(StringDao)ctx.getBean("edao");  
        String request = new String(" Wow, this works!");

        String response = dao.executeProcOneINParameter(request);  
        if (response != null && !response.equals(new String())) {
            System.out.println("stored proc worked: "+ response);

        } else {
            System.err.println("stored proc did not work.");
        }
    }  

}

StringDao.java

package test.jdbc;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.simple.SimpleJdbcCall;

public class StringDao {

    private static final String PROC_NAME = "PROCONEINPARAMETER";
    private static final String CAT_NAME = "LISTENER";
    private JdbcTemplate jdbcTemplate;

    public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
        this.jdbcTemplate = jdbcTemplate;
    }

    public String executeProcOneINParameter(String callParam){
        SimpleJdbcCall jdbcCall = new SimpleJdbcCall(jdbcTemplate)
                .withCatalogName(CAT_NAME)
                .withProcedureName(PROC_NAME);

        return jdbcCall.executeFunction(String.class, callParam);
    }

}

Stored Proc:

PROCONEINPARAMETER

CREATE OR REPLACE PROCEDURE procOneINParameter(param1 IN VARCHAR2)
IS
BEGIN

  DBMS_OUTPUT.PUT_LINE('Hello World IN parameter ' || param1);

END;

Answer 1

You are trying to call a procedure, not a function. But you are calling it via the executeFunction() method, and specifying a return type of String.

You need to use execute() instead, still passing the procedure argument, but without the return type (since there isn't one from a procedure):

Map<String,Object> out = jdbcCall.execute(callParam);

Your procedure doesn't have any OUT parameters either so out will be empty.
