I know this is a stupid question. But I really have very limited knowledge in programming. I've experience writing PHP code back in school, and I know that there is a framework called codeigniter, which includes very basic functions and libraries used for facilitating PHP programming.
Is Java EE to Java and WebLogic like codeigniter to PHP and some php-based web application (e.g., a forum)? I mean, is Java EE a framework or something like that?
Java EE is not a framework. It is a seperate edition of java for Web development process. for deploy(run) web application we need a server. Weblogic is one of the server.
Java EE is a standard. According to this
Java Platform, Enterprise Edition (Java EE) 6 is the industry standard for enterprise Java computing. Utilize the new, lightweight Java EE 6 Web Profile to create next-generation web applications, and the full power of the Java EE 6 platform for enterprise applications. Developers will benefit from productivity improvements with more annotations, more POJOs, simplified packaging, and less XML configuration.
WebSphere Application Server, JBoss Application Server and other are implementations of the above mentioned standards.
Google really helps a lot, please look into it before posting :)
