You dont have to change anything in the EAR file. Let the EAR file be as it was earlier (when it was deploying properly). 

The changes you have to make is in the client.jar file which you are using to run the standalone client. The MANIFEST.MF file in that jar file should be edited to contain the Class-Path entry. The link that i posted in my earlier reply also mentions that

Furthermore, the folder structure should look something like this:

D:
  | |
  | |--- SomeFolder
  | |	|
  | |	|--- client.jar
  | |	|	|
  | |	|	|--- META-INF
  | |	|	|	|
  | |	|	|	|--- MANIFEST.MF
  | |	|	
  | |	|
  | |	|--- jbossall-client.jar
  |  

The MANIFEST.MF should contain something like:

  | Main-Class: lemonpress.client.SimpleSessionClient
  | Class-Path: jbossall-client.jar beans.jar
  | 
  | 

Note that the jarpath that you specify in the Class-Path entry is relative to the jar file. So in this case, the jbossall-client.jar file will be searched in the same folder as client.jar. Please go through the documentation that i posted earlier, for more details.
