1: LAMS not working: Error in lams.log file

Hello all,

I am trying to run LAMS from Eclipse 3.2. The application does not start, so I have checked the lams.log file and have the many error entries in the LOGIN PAGE. The SessionManager says:

"Failed on finding current system session with null sessionId".

I have attached the lams.log file in case of anybody wants to have a look.

My environment:
LAMS version : 2.1
OS: Windows XP
Eclipse version: 3.2
Integration with other LMS: no.

Please, could anybody tell me what this error mean and how can I fix it?

Thanks in advance.

Alicia

Your browser should be getting a cookie after that message, but instead it keeps requesting the page and not getting a cookie - until it's maxed out the number of jboss threads (250). I know Firefox automatically stops after 10 or so retries if it doesn't get a cookie - what browser are you using?

Also, are there any errors in your server.log?

Hi Jun-Dir,

My browser is Firefox 3.0.3. The error message appears in the console of Eclipse environment. On the other hand, I am checking the server.log file and indeed there are errors: from line 321 untill the end of the file.

The first error registered in the file says:

"Error configuring application listener of class org.lamsfoundation.lams.web.session.SetMaxTimeoutListener"

And this is its trace:

java.lang.ClassNotFoundException: org.lamsfoundation.lams.web.session.SetMaxTimeoutListener
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3617)
at org.apache.catalina.core.StandardContext.start(StandardContext.java:4104)
....

I want to believe that the rest of the errors are derived from this one.. aren't they? Bellow it is attached server.log file. Cheers!

Alicia.

Ah, that's a new file in lams_common - it may be that you updated the lams_tool_daco project, but not lams_common. It was added on 22/9/08 - you probably just need to update lams_common and re-run the copyfiles ant target from lams_build.

Hello Jun-DIR,

Thanks for the information. I have updated lams_common which involved the update of other related projects, but finally everything compiles! :)

Thanks again.

Alicia
