Forum LAMS for Tech-Heads - General Forum: Re: Building LAMS 2.3.4 on Mac OS X

Me alegro mucho oir de ti... Thanks for replying.

Since I had been fiddling around with the source I decided to download it again and
start from scratch. I modified common.properties and unix.properties as per the instructions. I also had to modify
lams_common/db/sql/insert_lams_unix_config_data.sql even though it wasn't in the instructions.

Then, following the order of build steps in the instructions, lams built perfectly with only a few warnings about deprecated methods.

Initially when I ran jboss I got an out of memory error, so I had to modify the jboss start script to allocate more memory:

$JAVA" -Xms128m -Xmx512m

And then jboss started perfectly:

2010-06-17 10:00:06,653 INFO [Server] JBoss (MX MicroKernel) [4.0.2 (build: CVSTag=JBoss_4_0_2 date=200505022023)] Started in 41s:197ms

But.... when I try to connect to lams (http://localhost:8080/lams), the browser just says waiting
and eventually finishes, but nothing appears and there are no errors on the jboss console!!

The weird thing is that when I try to stop jboss (with a CTRL-C) I get the following error message:

Java HotSpot(TM) 64-Bit Server VM warning: Exception java.lang.OutOfMemoryError occurred dispatching signal Unknown Signal to handler- the VM may need to be forcibly terminated

Which I don't understand. I am using a Macbook Pro, which as far as I know is not a 64 bit machine...

If I modify the amount of max memory, like:

$JAVA" -Xms128m -Xmx1024m

Which I think is a huge amount...

Then I do get something in the web browser, a purely text only login page (no images of colors) with the following information:

LAMS - Learning Activity Management System

Version 2.3.4
Login

Username:

Password:

Login

Forgot your password?
Help?

Version 2.3.4 © 2002-2010 LAMS Foundation.

And the jboss console shows:

2010-06-17 10:15:43,696 DEBUG [JspRedirectStrategy] ===>LOGIN PAGE: there is no auth obj in session or accessing login page before login succeed, auth obj created. session id: C67B02EB81F265C04A025F737224780D

2010-06-17 10:15:43,894 DEBUG [SessionManager] Failed on finding current system session with null sessionId

But if I try to login with the default sysadmin/sysadmin then the page just goes blank and the jboss console has the following info:

What could be wrong?

Any help will be gratefully appreciated.

Mil gracias y hasta luego.

Just a follow on from my earlier message. For one thing I think that Mac OS X SnowLeopard is 64 bits, which would explain the JVM message.

I was wondering if the problem is with jboss-4.0.2 so I downloaded jboss-5.1.0.GA, and it behaves a lot better (that is to say without lams installed). It starts and stops perfectly.

However, I when I try to build lams for it I get a compile error because eclipse cannot find javax.servlet classes. I managed to fix this problem and build and deploy lams by copying servlet-api.jar and jsp-api.jar from common/lib to  servlet/default/lib. However, now when I try to start jboss-5.1.0 I get the following error:

Is it actually possible to build, deploy and run lams on Mac? I am beginning to wonder...

Thanks,

Tim

Just a one liner to say don't worry. I realized that I was complicating life too much. I have downloaded the 2.4 version from the CVS, followed the instructions and it compiles and runs fin on my Mac...

Now lets see if I can actually do something with all this lovely source code.

Thanks anyway,

Tim

Sorry I didn't get to this before you figured it out!

If you need any help, please post here in the forums.

Thanks,

When I use the Author and try to drag and drop any tool onto the panel I get a popup message saying:

System Error

A following system error has occurred:

You may need to re-start LAMS Author to continue. Do you want to save the following information about this error to help fix this problem?


And in the jboss console I get the following:

It sounds like a classpath error. What can I do to fix it?
