RE: ContextListener executes twice
From: Riaz, Bob [mailto:[EMAIL PROTECTED] Subject: RE: ContextListener executes twice Does anyone know of a patch for this? I couldn't find one. The bug does *not* cause the Listener to be executed twice, since the second registration attempt is ignored; the message is purely cosmetic. If you read the whole thread you'll see that the double registration has been occurring in all 6.0 levels, but only recent ones started logging it. This isn't your problem. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: ContextListener executes twice
From: Riaz, Bob [mailto:[EMAIL PROTECTED] Subject: RE: ContextListener executes twice Ok. Removed it. But if the conf/Catalina/[host]/[appName].xml overrides this, this should make no difference, right? True, but there's no point in leaving invalid junk lying around just waiting to cause trouble. The JAVA_HOME variable points to the bin in the jdk folder, same error if JAVA_HOME points to jdk folder. JAVA_HOME must point to the directory one up from bin. Looks like the environment variable is not being seen by the process running the startup.bat script. Open up a command prompt window, cd to your Tomcat bin directory, enter a set command with no parameters and see what you've got. If JAVA_HOME is set properly, running startup.bat will get you something like this: Using CATALINA_BASE: C:\apache-tomcat-6.0.16 Using CATALINA_HOME: C:\apache-tomcat-6.0.16 Using CATALINA_TMPDIR: C:\apache-tomcat-6.0.16\temp Using JRE_HOME:C:\jdk1.6.0 (Yes, it says JRE_HOME, that's acceptable.) Tomcat will start running in another command prompt window. To check JAVA_HOME, try this: %JAVA_HOME%\bin\java.exe -version - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
