My system RAM is 512 MB. and i am managing to run jboss with it. I could find out that JBoss is calling many services which my project does not require. As of now we dont use topics/ejbs/queues/mail/messaging etc etc. I want to get rid of all these things. We are actually using only springs and jndi for database look up. How can i stop jboss from calling all these unnecessary services. I tried removing some jar/rar/xml files, but i think all are interdependent. I also tried to comment some lines in the jboss-service.xml but i dont think what i did is correct. So how and where should i modify the xmls/configuration files in such a way that the unnecessary services are not called.?????
