Error during Upgrade process from IDM5.0 to IDM 6.0

Hi,

I have installed Identity manager 5.0 on my system. Now i want to upgrade to IDM 6.0 (2005Q4M3). I got the following error during upgrade process.

Problem during execution: java.lang.NoSuchMethodError: com.waveset.install.SetupUtil.importFile(Ljava/io/File;)V

com.waveset.install.SetupUtil.importFile(Ljava/io/File;)V

my system details:

OS: Microsoft Windows 2000 Advanced Server

Application Server: Tomcat 4.1

Java: jdk1.4.2

DataBase: MySQL 4.1.19

Process i followed:

1) i started MySQL and update the databse schema by running the script "upgradeto2005Q4M3.mysql" provided in the upgrade package.

2) i make sure that my application server is stopped.

3) i run the install.bat file from "IDPAK_2005Q4M3" upgrade package, which launch a GUI interface.

4) as a first step i select upgrade.

5) after that i selected the IDM directory as tomcat\webapps\idm where my previous IDM was installed.

6) after that on clicking next, it completes the process of pre-Upgrading , install the components.

7) during the process of post-upgrading i get the following error:

Problem during execution: java.lang.NoSuchMethodError: com.waveset.install.SetupUtil.importFile(Ljava/io/File;)V

com.waveset.install.SetupUtil.importFile(Ljava/io/File;)V

i am not able to resolve the above error.

Can anyone please guide me?

Are you sure that your original 5.0 was working?Also - there is a manual upgrade process - you can try that as an option. If that too fails, I will suspect that your installer is not complete, try getting a new installer from the sun download site.
