J2EE Tutorial examples compile problems

Question

I wanna try to compile the examples that came with the tutorial but I
don't succeed.
Here are the error messages:
[root:/usr/local/j2eetutorial/examples]$ ant all
Buildfile: build.xml
init:

[root:/usr/local/j2eetutorial/examples]$
I set the environment according the instructions in the tutorial:
J2EE_HOME=/usr/local/j2sdkee1.3.1
JAVA_HOME=/usr/local/j2sdk1.4.1_01
ANT=/usr/local/jakarta-ant-1.3
PATH=$PATH:$J2EE_HOME/bin:$JAVA_HOME/bin:$ANT/bin
export J2EE_HOME JAVA_HOME ANT PATH
but I suspect the problem lies within 'build.xml'. These are lines 19
through 24:
<property environment="myenv" />
<property name="j2eepath" value="${myenv.J2EE_HOME}/lib/j2ee.jar" />
<property name="webpath" value="${webejb}" />
<property name="connector-lib" value="${myenv.J2EE_HOME}/lib/connector" />
<property name="cloud-lib" value="${myenv.J2EE_HOME}/lib/cloudscape" />
<property name="system-lib" value="${myenv.J2EE_HOME}/lib/system" />
Line 19 mentions "myenv" but I never set anything like that. Maybe I
should edit this line?
Any ideas?
Thanks
Nick.

Had the same error myself. Seems to be an issue with ant, I upgraded to ant 1.5.3.beta1 and it built fine. Hope this helps somewhat.
