How to Call Stored Proc. through JDBC from SQL Server

Question

I have to call Stored Procedure by JDBC in java. This is the prog i m using:
import java.sql.*;
import java.io.*;
class callSP
public static void main(String a[]) throws Exception
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection c=DriverManager.getConnection("jdbc:odbc:first","sa","");
//CallableStatement cs=c.prepareCall("{? =call GET_CLUSTER(?)}");
CallableStatement cs=c.prepareCall("{call GET_CLUSTER(?)}");
cs.registerOutParameter(1,Types.CHAR);
//cs.setString(1, "Teamwork");
cs.execute();
//cs.executeUpdate();
String output=cs.getString(1);
System.out.println(output);
catch (SQLException e)
System.out.println(e);
This is the Stored Procedure:
CREATE PROCEDURE GET_CLUSTER
@Ip_THESAURUS_KEY_WORD CHAR(40)
AS
DECLARE @Lc_THESAURUS_CODE INT,
@Lc_CLUSTER_CODE INT
BEGIN
--GET THE THESARUS CODE FOR THE KEYWORD
SELECT @Lc_THESAURUS_CODE = THESAURUS_CODE
FROM THESAURUS_LIST
WHERE THESAURUS_KEY_WORD = @Ip_THESAURUS_KEY_WORD
--GETTING THE CLUSTER ID
SELECT @Lc_CLUSTER_CODE = CLUSTER_CODE
FROM THESAURUS_ENRICH_CLUSTER
WHERE THESAURUS_CODE = @Lc_THESAURUS_CODE
--GET THE CLUSTER KEYWORDS
SELECT THESAURUS_KEY_WORD
FROM THESAURUS_LIST T,THESAURUS_ENRICH_CLUSTER C
WHERE T.THESAURUS_CODE=C.THESAURUS_CODE
AND C.CLUSTER_CODE=@Lc_CLUSTER_CODE AND NOT THESAURUS_KEY_WORD=@Ip_THESAURUS_KEY_WORD
END
GO
Check it out what is problem. Data is not getting, it is giving exception.

Please be specific regarding the problem that you are facing, that's the key to getting help in the forum. If there's exception in your program, such as NullPointerException or SQLException, please state it in your post.
