问题 I am working on a Java application which uses Servlets, an application server, JMS, JMX etc. So is this a Java EE application?

You have a Java EE application if you can package it as a .war or an .ear and deploy it according to the Java EE standards. If you have a stand-alone application which uses JMS, it doesn't make it a Java EE application

Maybe there is a similar functionality for webshere, but typically you need to hire a ibm consultant to "find" the configuration. 回答2: Some application servers/servlet containers (Tomcat, JBoss) provide the cross context feature.

问题 I need to run my Java application on cPanel . I have successfully installed Tomcat, I can run my application by copying war file into my www folder but the problem is that it shows the Project name ( war file name) in the address, I need to know how to remove that, so users can access www.example.com rather than www.example.com/MyProject/index.jsp ? 回答1: According to one cpanel hosting service command prompt access is generally turned off for cpanel for security reasons and you have to ask
