Help, I kept getting compilation error "package javax.ejb does not exist"

[L. Wei]

I am a newbie to EJB and now reading EJB3 in Action. I am trying to run the example of Chapter1. I am setting up JBoss AS 5.1.0.GA and Ant on Mac OSX. I downloaded sample zip file from the book website, and tried to compile the 1st chapter. However, I kept getting the compilation error "package javax.ejb does not exist" while using ant. I tried to modify the build.xml file under the chapter1 folder, but still couldn't get it compiled. I couldn't find any solution in the sample instruction pdf file. Where is the jar file should I include for package javax.ejb? so frustrated...

Here is the build.xml file.

I did setup JBOSS_HOME and added ant in the PATH. What did I miss in the setup? Please help...

Your ant script is using the common.j2ee.class.path property to define where the J2EE jars are. I guess it is defined in the imported ../common.xml. Can you show the content of common.xml ?
