Different Contextes One Instance?
Hi All! TC 3.3 has a class loader architecture which allowes to load classes with respect to the container, to all web applics and to a specific web applic. The question I have is the following. I have developed some components which are inteded to be used by all of our web applics. One of this component for instance is a database connection pool manager. It is implemented as a Singleton. So, if I put the .jar file into the directory $TOMCAT_HOME/lib/apps and for instance there are three wep applics using it, how mucht Singleton does the VM maintain? Three (one in each context) or one for all contextes. Many Thanks in advance Erwin -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]

There would be a single instance, but all threading and concurency issues would be up to you to handle.
