I have found a bug in a Struts application I am developing at work, and I am having trouble figuring out what might be causing it. I will give the brief overview below, and be happy to dive into as much detail as might be needed.
The problem: I have started adding logging to several of my action classes and have started noticing that some of them are being called twice in quick succession. I know for a fact that it's not a user double-clicking to submit a form; I can reproduce it (only some of the ActionClasses have this problem, but they have it consistently. To help illustrate the problem, I have an excerpt of the log below, showing that the ActionClass was called twice: // the first time the action class was called 16:41:11,897 - Checking required permissions 16:41:11,898 - Starting performTask() method 16:41:11,898 - performTask(): Got session attributes; 16:41:11,900 - performTask(): Removing old contexts 16:41:11,900 - performTask(): Calling getAvailableContexts() 16:41:12,728 - performTask(): Got 2 contexts 16:41:12,740 - performTask(): Adding LVBean[Example 1, 0001] 16:41:12,741 - performTask(): Adding LVBean[Example 2, 0026] 16:41:12,741 - performTask(): Setting roles vector 16:41:12,742 - Ending performTask() method // the second time the action class was called, < 1 second later 16:41:13,039 - Checking required permissions 16:41:13,040 - Starting performTask() method 16:41:13,040 - performTask(): Got session attributes; 16:41:13,043 - performTask(): Removing old contexts 16:41:13,044 - performTask(): Calling getAvailableContexts() 16:41:13,853 - performTask(): Got 2 contexts 16:41:13,854 - performTask(): Adding LVBean[Example 1, 0001] 16:41:13,854 - performTask(): Adding LVBean[Example 2, 0026] 16:41:13,855 - performTask(): Setting roles vector 16:41:13,855 - Ending performTask() method Again, I will be happy to post code samples upon request, but I don't want to clutter the issue quite yet. Struts Version- I am using a Struts nightly build from December 2001, but I can reproduce the problem under the most recent 1.1 beta of Struts (which I downloaded earlier today). The Server- RedHat Linux 7.2, fully patched, running with Caucho Resin-2.1.2 and Sun JDK 1.3.1_04 (latest 1.3.1 JVM). I can reproduce this problem on multiple machines with several different versions of Resin (up to 2.1.4). Any ideas at what might be causing this, or how to diagnose it? Thanks in advance for any help or advice you can give. Tom -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
