Optimize how the InitialContext is created in org.jboss.seam.util.Naming ------------------------------------------------------------------------ Key: JBSEAM-3485 URL: https://jira.jboss.org/jira/browse/JBSEAM-3485 Project: Seam Issue Type: Task Components: Core Affects Versions: 2.1.0.BETA1 Reporter: Jay Balunas Fix For: 2.1.1.CR1 Attachments: patch.txt Seam currently only creates and manages the InitialContext in the "org.jboss.seam.util.Naming" class (see: http://fisheye.jboss.org/browse/Seam/trunk/src/main/org/jboss/seam/util/N... ). The properties are set in one location and done only once during the initialization of seam (see: http://fisheye.jboss.org/browse/Seam/trunk/src/main/org/jboss/seam/init/I... ). I see two issues here although they are related. The first issue would require some caching mechanism or logic for reuse of the InitialContext instance instead of recreating it every time. WE need to determine when it makes sense to reuse an instance of the InitialContext, and when we need to get it fresh. We currently use they exact same properties to initialize it and those are set during Seam initialization and do not appear to ever change once created. The second issue is that we do a certain amount of processing every time the context is requested, this could be optimized. Currently I see a few blocked threads on the "props.size()" call in the Naming class which is a synchronized method on the Hashtable. We need to maintain the logic that if the property list is empty we continue to call "new InitialContext()" and not pass in the properties object. This is because the first thing the InitialContext constructor does with a properties object is clone it which can be costly. This change is not as important if we find a way to cache the initial context. I have attached a patch that implements these changes. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
