compiling jdbc with JDK 1.1.3

Hello,

I'm novice in java programming, but advanced in PostreSQL.

I get the following error while compiling jdbc source:

javac postgresql/CallableStatement.java
postgresql/CallableStatement.java:37: Can't subclass interfaces: interface
java.sql.PreparedStatement
public class CallableStatement extends PreparedStatement implements
java.sql.CallableStatement
^
Do you have any ideas how to solve this problem?

Thanks in advance.
