Blu Age L3 Workshop

The issue you're experiencing with the "Create dataset from LISTCAT" option in the Blu Age L3 Workshop BAC (Blusam Administration Console) is likely related to configuration or caching problems that occurred after your AppStream session ended and restarted. Here are some steps you can try to resolve this issue:

1. Clear your browser cache: The problem might be caused by cached data from your previous session. Try clearing your browser cache and cookies, then log in to the BAC console again.

2. Verify Tomcat configuration: Ensure that all required datasources (jics, bluesam, bac, primary) are correctly configured in your Tomcat configuration files (context.xml and server.xml). Incorrect configurations can lead to errors when trying to create datasets.

3. Synchronize configurations: Run the Publish action on the Tomcat server to synchronize everything between the Eclipse WST working folder and the Tomcat configuration folder. This can help resolve issues caused by mismatched configurations.

4. Check server logs: Look at the Tomcat server logs for any specific error messages that might provide more insight into why the "Create dataset from LISTCAT" option is failing.

5. Restart Tomcat: Try stopping and restarting the Tomcat server to ensure all configurations are properly loaded.

6. Verify file permissions: Ensure that the application has the necessary access rights to create and modify files in the relevant directories.

If these steps don't resolve the issue, you may need to review the workshop documentation for any specific instructions related to dataset creation or reach out to the workshop support team for further assistance. The errors you're encountering might require a more in-depth investigation of your specific setup.
