I really don't like ILog JRules

I'm using JRules 6.5.3. I am not loving it. It is really slow.

There is an eclipse-based IDE called ILog Rule Studio. It works somewhat, but builds are slow and you can't use the most recent jvm.

It is restricted to Java 1.4 and Java 5. If you use anything more current, some features of the ILog plug-ins won't work. Ruleset or RuleApp exports did not work until I installed the latest 1.5 JDK.

To use JRules you go through a process of "verbalization". You associate, hopefully, understandable English phases with java code. But doing a verbalization is painfully slow. When you verbalize, the save operation takes an amazing amount of time. I would say 10-30 seconds.

OpenLDAP wouldn't start. Here's how I fixed it.

Yesterday, a power outage brought my computer at work crashing down. When I tried to get my development environment going again, I couldn't interact with my local OpenLDAP server.

The slapd.exe process would essentially hang. I killed the process, and started it from the command line:

$ slapd -d -1


This showed that the process was hanging after loading a file in the data directory.

So I zipped up (zip file) the data directory. and then deleted the contents. Now, it would start up.

But there are no entries in the directory now. So I import an ldif file and, Voila!, I'm back in business.
