Eclipse + Seam + TestNG Tricky

TestNG gives "Connection Refused" while running on Eclipse

While running TestNG in Eclipse there
will always be 2 VMs involved: the VM of Eclipse and the VM running
the tests. In order to update the plugin UI the 2 VMs are
communicating over a port using a very simple string based protocol.
The exception you are seeing is telling that the 2 VMs are not able to
talk to each other. This is a weird exception that would translate
into: there was impossible to open a communication port between the 2
VMs involved. Off hand, the cause may be: a bug in Eclipse/plugin or
maybe a firewall/antivirus that blocks this.

TestNG/Seam reports ClassNotFoundException issues

This is mostly caused by Class Path configuration, also, Java 6 may be the cause, use Java 5!!

It seems that it does not like space in the path T_T, try to set the workspace to somewhere with NO space!! FUCK!

When running test case in Eclipse, TestNG complains bad version in .class file even Java 5 is used

java.lang.UnsupportedClassVersionError: Bad version number in .class file

Make sure everything is Java 5 compliant, such as:

• Project build path


• JAVA_HOME, JRE_HOME


• Java's in PATH (check by java -version)


• The Application Server (i.e. must be JDK5 compiled JBoss AS 5)
