It may be a computer problem, often the system suddenly automatically restarts. Eclipse3.0.1 and jboss3.0.0.1 and jboss3.2.3 (using Lomboz3 plugins) are suddenly closed, and it is actually closed. After restarting, start JBOS in Eclipse There will be SQL anomalies, such as SQL is connected, etc. I have deleted the JBoss installation directory in the past, then re-explain the JBOSS compression package, which is absolutely. However, there is this situation today, I Try to delete files or directories, work, tmp, etc. that may be locked, and finally discover that is a Data / Hypersonic directory. The localdb.script file may be a key file, but I didn't find what is associated, it is the file lock. It is still the setting of a attribute, it is unclear. It's a good problem to solve it, directly delete this Data directory.
