Hi, I am using Keetle2.2.2, Java1.4.2_04 and the Window XP version 2002 with Pentium4 3GHz,504 MB of RAM. When I start the keetle, after verifying the admin password it gives me the error as "Unable to read the transformation from repository" and a big list of java errors


An error occured reading a transformation from the repository

after clicking on the close button the spoon window does appear but when i run a new transformation or any other transformation the same error message comes saying that "an error occuring reading a transformation from the repository.".






i have posted the same query on the 1st of feb 2006 the reply to which "use the kettle2.2.2".but the problem is not yet solved.
i am also sending you the transformation's xml file if it could be of any help for you which is attached as the C:\Documents and Settings\db27422\Desktop\dinesh_trans.ktr






could you please tell me where actually the error lies?



thanks in advance.

Hi,


The problem seems to be solved if the jdbc of mysql is upgraded to mysql driver mysql-connector-java-3.1.12-bin instead of the mysql-connector-java-3.1.7-bin version that is in the libext folder.
I just copied the .12 version of the JDBC in the mentioned folder, and renamed it as mysql-connector-java-3.1.7-bin (otherwise kettle does not find it )



cheers
