I am in the process of converting hypersonic to mysql, and made some changes to the relevant files.
Although I didn't backup the whole tree, I made backups of the relevant files.
Just went back to the old hypersonic setup, and hypersonic won't receive connections. It appears to start in the log, but when I add my jar file (which has been working for a year now), it gives me:
2003-11-23 12:54:56,271 ERROR [org.jboss.ejb.EntityContainer] Starting failed
org.jboss.deployment.DeploymentException: Error while checking if table aleady exists; - nested throwable: (java.sql.SQLException: Connection is broken: Software caused connection abort: recv failed)
and this creates other problems down the road. I have checked the hsqldb-ds file several times, and it's right. the only change is in the file modified time and the last deployed time.
this won't work at all anymore -- i deleted all the old hsqldb data (and all directories except conf, deploy, farm and lib in the default tree) and went back to what i think is the original version in all respects. still shows that hsqldb is starting up, but won't let a connection go through once it has to deal with ejbs.
i really have no clue as to whats going on if it doesnt have something to do with the date that the file was modified, as the file is identical to the one that ships and i havent changed anything else afaik.
