Simple Grid Report Example using Basic Oracle Stored Procedure in Japser Design Studio 6.1 Pro

Hi,
In this post you will see how to work with a basic oracle stored procedure.

Software Setup : 
1) Oracle SQL developer  Version 4.0.3.16
2) Japsersoft Design Studio 6.1 Professional 
3) Jasperserver 6.2 professional 
4) Oracle Version : Express Edition

Aim of the report : Display employee data as a grid 

1) Connecting to XE schema in database client tool ( i.e., Oracle SQL developer)

NOTE :  Default username and password while installing Oracle Expression
USER NAME : SYS
PASSWORD : AS SYSDBA

conn sadakar/sadakar
Syntax : conn schemaName/Password

2) Writing Stored Procedure on "emp" table ("emp" table comes with oracle 11g installation). 


create or replace procedure "REF_CURSOR_SAMPLE"
(emp_cursor  IN OUT SYS_REFCURSOR)
as
begin
  open emp_cursor for
    select * from emp;
end ref_cursor_sample;


3) Create a simple JRXML and in the Query editor change the language type to "plsql" and call the above stored procedure as follows 
{       call REF_CURSOR_SAMPLE($P{ORACLE_REF_CURSOR})        } 

Syntax : { call procedureName(param1,param2,$P{ORACLE_REF_CURSOR})}

 4) Create a parameter called "ORACLE_REF_CURSOR" in parameters Outline section and write its type as java.sql.ResultSet

5) In the query editor manually type the field names and provide types to them as shown in below image

  
NOTE : If you click on "Read fields" button you may see or stop with below error message
net.sf.jasperreports.engine.JRException: Error preparing statement for executing the report query:

{call REF_CURSOR_SAMPLE($P{ORACLE_REF_CURSOR})}

Caused by: java.sql.SQLException: Invalid column type: 2000 

 6) Design the report and save then preview it. 



7) Japsersoft Design studio preview  of the report. 

Report output in Jasper server:

Configure PL/SQL for Japserserver (5.5 or later)
It can be found at http://community.jaspersoft.com/wiki/config-stored-procedures-jasperreports-server-55

After successful configuration publish the report to the server and check the output.



NOTE : Create oracle "XE" data source connection before publishing the report.  Sample connection is shown in below image.
