weblogment
leaving an extra long comment on someone's myspace page.
Hey Karen, sorry about the weblogment I left on your page last night.
weblogic
A web server commonly used to host Java enterprise applications. It works just good enough that it is not cast aside, but not poor enough that someone has been convinced to write a better tool. Frequently, unexpected errors will surface without justification, and can be solved by restarting the server.
User 1: Why doesn't this damned thing work!?!
User 2: Have you tried restarting the weblogic server?
User 1: ...DAMMIT! Now it works!
