Question

I am trying start jboss and I have an error. I use jboss 7.1.1 and Liferay. What is wrong?

Answer 1

Step 1: To setup machine for Liferay development first of all you will need to download and install all required software as described below.
JAVA (JDK & JRE)
http://www.oracle.com/technetwork/java/javase/downloads/index.html
Eclipse IDE
http://www.eclipse.org/downloads/
Liferay JBOSS bundle (Community Edition or Enterprise Edition as per your requirements and preferences), Liferay Tomcat bundle (For server run time selection), Liferay Plugin SDK (For Development of plugins like hooks, portlets, themes etc.
http://www.liferay.com/downloads/liferay-portal/available-releases
Apache Ant (For build and deployment of projects).
Step 2: Now set environment variables in your machine.
Set JAVA_HOME
Set JBOSS_HOME
Set LIFERAY_HOME
Set ANT_HOME
Step 3: Open Eclipse and install Liferay IDE.
Go to Help -> Eclipse Marketplace
Search for "Liferay".
Install Liferay IDE and restart eclipse.
Step 4: To configure Liferay Plugin-SDK
Go to Window -> Preferences -> Liferay
Add Liferay Plugin-SDK
Here you will option to update build.<username>.properties file. Select
prompt.
That's it your system is ready with development environment for Liferay.
Step 6: In Liferay Plugin-SDK folder there will be a file called
build.username.properties
Set path of server to refer JBOSS directory.
Step 7:Create new Liferay Plugin Project.
Inside that Create New Portlet Project.
Select Liferay Portal Runtime as Tomcat, because Eclipse doesn't provide
runtime for JBOSS Application server so use some tricky way to deal with it.
After clicking on finish it will ask for updating build.<username>.properties file.
Select "No" option.
Okay Now you are done with project creation and Setting deployment server
as JBOSS.
Step 8: Deploy Liferay Portlet Project.
Step 9: Run standalone.bat from bin directory of JBOSS

Answer 2

Check your jboss-deployment-structure.xml file in ROOT.war/WEB-INF/ location to see any of the dependency modules mentioned in there uses ant-*.jars. The issue could be due to multiple jars with the same classname in the classpath.

Answer 3

new liferay versions provide a wildfly bundle... this could be a starting point, neverthelesse ClassNotFound typically originates from missing jars in that special context, whether physically or suppressed by the jboss modul-system ( starting is here the deployment-structure file, or even worse the module directory of your installation)
but in the end a guy like me decides often to get a new working environment before diving into that voluntarily...
