I'm trying to build zimbra from the source code on eclipse ( I have followed the instructions of INSTALL.txt)

My OS : windows xp
Java 1.5
Tomcat version 5.5
Openldap version 2.2.28

When running the "reset-the-world" the build process cancels with the following error:

[javac] C:\workspace_eclipse\ZimbraServer\src\java\com\zimbra\cs\db\DebugConnection.java:39: com.zimbra.cs.db.DebugConnection is not abstract and does not override abstract method createStruct(java.lang.String,java.lang.Object[]) in java.sql.Connection
    [javac] class DebugConnection implements Connection {
    [javac] ^

    [javac] 2 errors

running "deploy" and "admin-deploy" build successfully, I can see the authentication screen but I can't log in

please I need a solution to solve this problem.
