- Open DMT from AIC Portal
- Configure DB2 UDB using the option "Live connection to your DB2 UDB Server".
- Enter the DB2 details and add manually the list of schema to extract.
- Click package.
- The packaging fails at the Extraction step.
- This issue occurs because the file ByteToCharConverter class does not exist in your <Your Java Folder>\lib\rt.jar file that is in your Java Installation folder.
- Close the DMT.
- To check that point, open the rt.jar as an archive file (using an archiver utility like 7z or Winrar)
- Go to the folder sun\io\. The file ByteToCharConverter.class file does not exist :
- If it does not exist you must add the db2jcc4.jar jar file in your <JAVA INSTALLATION FOLDER>\jre<version>\lib\ext
- Open the DMT
- Package the DB2 UDB schema again.
- If the issue still exists use the JAVA Version 7 instead of the one installed on your machine.
- If the issue still occurs, contact CAST Technical Support with the Relevant Input
