Hi,
I have solved the problem. Still, I am getting problem while i am running the class file. I se the CLASSPATH as
Set CLASSPATH=c:\j2sdk1.4.0_01\jre\lib\rt.jar;
set CLASSPATH=%CLASSPATH%;c:\weblogic\lib\weblogic.jar;
Still, I am getting the following error:
Exception in thread "main" java.lang.AbstractMethodError racle.jdbc.driver.OraclePrepareStatement.getParameterMetaData()Ljava/sql/ParameterMetaData;
at Test.main(Test.java:20)
My Source Code:

import java.io.*;
import java.sql.*;
import java.util.*;
public class Test {
public static void main(String args[]) {
 
try { 
 
Properties props = new Properties();
props.put("user", "scott");
props.put("password", "tiger");
 
Driver d = (Driver)Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
Connection con = d.connect("jdbc:oracle:thin:@lm1:1521:lm1", props);
 
PreparedStatement ps = con.prepareStatement ("{call insertDept(?,?,?)}");
 
ParameterMetaData pmd = ps.getParameterMetaData();
 
System.out.println(pmd.getParameterType(1));
System.out.println(pmd.getParameterType(2));
System.out.println(pmd.getParameterType(3));
 
ps.close();
 
} catch (Exception e) {
System.out.println("<Exception>"+e.getMessage());
}
} 
}

"Senthamizh",
The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp.
We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please edit your profile and select a new name which meets the requirements.
Thanks.

From the Javadocs:

java.lang.AbstractMethodError Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.

Try recompiling your class before running it. It appears that it was compiled against one library and is running against a different version.

David O'Meara,
Thanks, I have changed my Display Name. I was recompiled my Program. I am getting the same problem. Please Explain in detail.

Yes, David is correct. You compiled with a newer version of the API that has the method in question, and you are running with an older version, that does not have any implementation for the method. It's either you reecompile and run with teh same version of the JDBC API or don't use any statements that are only available with the newer version.

Hi,
OK, Please, Explain how do i use ParameterMetaData in my Program. What JVM and Java API version it should support?
