Hi all, is it possible to limit somehow allowed memory for some code block (method for example)? For example, I am going to run some code but it is possible that it can try to use too much memory (heap or stack). The practical usage of such limitation can be: preventing some plugin to suck all...

Hi, i have stored procedure (or function) and I need to return records set from it. This result set is generated inside SP, so simple select <some columns> from <somewhere> will not work. In postgresql this is done using SET OF construction, but how to do it in MySQL?

Hello! I have trigger and in some condition I want to inform calling system that some error occured (rise error). How can I do it? And where can I read about it? Official documentation is not very helpful, at least I didn't found anything about it in section triggers. :(

I just remember that in some article on IBM site I saw somethink about the reasons why SE5 generics are not so cool as they could be. It was some compatibility reason as I understood, so if specs WAS changed, then compatibility is already broken and there is no need to worry about it. But there...

Don't know whats wrong in your case but here is my configs ( tomcat-5.0.28 ): ---httpd.conf--- <IfModule !mod_jk.c> LoadModule jk_module "modules/mod_jk.so" </IfModule> JkWorkersFile "conf/workers.properties" JkLogFile "logs/mod_jk.log" JkLogLevel info JkMount /servlets-examples/* worker1...

Computers in LAN access internet thru special server and for all other internet they looks like single computer ( same IP ). How can I know, is there only one computer using that IP or there is more of them, and if there is more, then which of them exactly ( IP ) uses it now? I mean...
