Today, I didn't understand, I didn't understand, put EJB deployed, IMPORT corresponding package, actually call EJB failed.
Copy the JAR package to the web-inf / lib directory or unpack it into the class of the class.
It is reasonable, but this actually has to do it manually. A little wonderful.
PS: The deployment of the JAR package of EJB is copied to the corresponding directory, then modify the config.xml file to point to the JAR package under the corresponding path.
