Both technologies can compete fiercely, and they can work closely together. From the customer's point of view, the integration of technology is very important, because a large application system, often cannot be done independently by a single language/and technology. The advent of Php/java Bridge will be a bridge between PHP and Java, providing a good choice for companies that need to combine PHP with Java.

Haohappy not deep understanding of the Java EE, if the relevant content to understand the error, welcome criticism advice.

(a) What is a JSR and what is JSR223?

The JSR (Java specification request) is a formal request to JCP (Java Community Process) to propose a new standardized technical specification. Anyone can submit a JSR (Java spec request) to add new APIs and services to the Java platform. JSR has become an important standard in the Java world.

In the Java servlet specification (servlet 2.4,jsr-154), a series of core abstract concepts (various objects to be considered during Web application processing) are defined to allow Java programmers to write web programs, including Session,request, Response and so on. When programmers are writing programs, it is convenient and safe to communicate with these objects. JSR223 describes how these Java objects are open to Web pages written in other scripting languages, allowing other languages to access those objects as well. The current specification will be used in PHP, but this concept is independent of the scripting language, meaning that it may be used in future scripting languages other than PHP. In a word, the purpose of JSR223 is to integrate the scripting language onto the Java platform.

(b) What is Php/java Bridge?

Php/java Bridge contains a PHP module (including Java.so,php_java.dll) and a related back-end program (Javabridge.jar,javabridge.war or MonoBridge.exe), The object system used to connect PHP to the Java or ECMA 335 (CLI, an important subset of the Microsoft. NET framework) virtual machines. It fully implements the JSR 223 specification request, allowing PHP scripts to access applications based on the CLR (such as vb.net,c#) or Java (Java,kawa,jruby). Php/java Bridge communicates with a virtual machine via a local socket with an efficient communication protocol. A multi-process ">javax.script package.
