NPAPI Wikipedia. Netscape Plugin Application Programming Interface NPAPI is an application programming interface API that allows plugins more specifically, browser extensions to be developed for web browsers. It was first developed for Netscape browsers, starting in 1. Netscape Navigator 2. In NPAPI architecture, a plugin declares content types e. Edit Article wiki How to Clear Your Browsers Cache.

Firefox For Yosemite Download' title='Firefox For Yosemite Download' />When the browser encounters a content type it cannot handle natively, it loads the appropriate plugin, sets aside space within the browser context for the plugin to render and then streams data to it. The plugin is responsible for rendering the data. The plugin runs in place within the page, as opposed to older browsers that had to launch an external application to handle unknown content types. NPAPI requires each plugin to implement and expose approximately 1. NPAPI also supports scripting, printing, full screen plugins, windowless plugins and content streaming. Scripting supporteditScripting is a feature allowing Java.

Various versions of Netscape and then Mozilla supported this feature using different technologies, including Live. Connect, XPConnect, and NPRuntime. Live. ConnecteditLive. Connect is a feature of Web browsers that allows Java and Java. Script software to intercommunicate within a Web page. From the Java side it allows an applet to invoke the embedded scripts of a page or to access the built in Java. Script environment, much as scripts can. Conversely, from the Java. Script side, it allows a script to invoke applet methods, or to access the Java runtime libraries, much as applets can. Live. Connect was used in Netscape 4 to implement scriptability of NPAPI plugins. The Open Java Interface dependent implementation of Live. Connect was removed from the Mozilla source code tree in late June 2. Mozilla 2 cleanup effort. It is no longer needed with the release of a redesigned Java Runtime Environment from Sun Microsystems. However the old implementation was restored for Gecko 1. Apple had yet to port the newer JRE over to Mac OS X. The JavaJava. Script functionality supported by the redesigned Java Runtime Environment is still called Live. Connect, despite the Open Java Interface specific approach having been abandoned. With Netscape 4, NPAPI was extended to allow plugins to be scripted. This extension is called Live. Connect. A plugin could implement a Javaclass and expose an instance of it. The class could be called from Java. Script and from Java applets running within the page. The disadvantage of Live. Connect is that it is heavily tied to the version of Java embedded within the Netscape browser. This prevented the browser from using other Java runtimes, and added bloat to the browser download size since it required Java to script plugins. Additionally, Live. Connect is tricky to program The developer has to define a Java class for the plugin, run it through a specialized Java headercompiler and implement the native methods. Manual Microsoft Project Pdf Espanol. Handling strings, exceptions and other Java objects from C is non obvious. In addition, Live. Connect uses an earlier and now obsolete application programming interface API for invoking native C calls from Java, called JRI. The JRI technology has long since been supplanted by JNI. XPConnecteditXPConnect Cross Platform Connect is a technology which enables simple interoperation between XPCOM and Java. Script. Object connectioneditXPConnect allows Java. Script objects to transparently access and manipulate XPCOM objects. It also enables Java. Script objects to present XPCOM compliant interfaces to be called by XPCOM objects. A main goal is that objects communicating from either side of an XPCOM style interface should not generally need to know or care about the implementation language of the object on the other side of the interface. XPConnects primary reason for existence is to replace handwritten code used in places where native code needs to interact with Java. Script code. An example is the DOM module. SecurityeditFull privileges are only granted by default to chrome scripts, i. For remote HTMLXHTMLXUL documents, most XPCOM objects are not accessible by the scripts as they have limited privileges due to security reasons. Even if they are accessible e. XMLHttp. Request object, the usual security restrictions can also be found e. URLs of other domains. Mozilla was already using XPCOM to define the interfaces to many objects implemented in C. Each interface was defined by an IDL file, and run through an IDL compiler that produced header files and a language neutral type library that was a binary representation of the interface. This binary described the interface, the methods, the parameters, the data structures and enumerations. XPConnect uses the type library information to marshal calls between different thread contexts and between Java. Script and natively compiled C. XPConnect is used extensively throughout Mozilla. Starting with Netscape 6. Mozilla 0. 9. 2, NPAPI was extended, so that a plugin could return a scriptable interface to itself and XPConnect would marshal calls to it from Java. Script and the C implementation. XPConnect has no Java dependency. However, the technology is based on XPCOM. Thus the plugin developer must be familiar with reference counting, interfaces and IDL to implement scripting. The dependency on XPCOM led to certain dynamic linking issues e. XPCOM has since been changed to supply a statically linked version to address such issues. This approach also requires an. DLL otherwise the plugin appears to work, but the scripting does not, causing confusion. NPRuntimeeditAt the end of 2. NPAPI agreed on NPRuntime6 as an extension to the original NPAPI to supply scripting, via an API that is similar in style to the old C style NPAPI and is independent of other browser technologies like Java or XPCOM. It is only supported by Firefox ESR Extended Support Release and Safari. Browser supporteditThe following web browsers support all NPAPI plugins Because of the age of the API, security issues, and adoption of alternative technologies such as HTML5, major web browser vendors began to phase out NPAPI support in 2. Internet Explorer versions 3 through 5. SP2 supported NPAPI, allowing plugins that functioned in Netscape Navigator to function in Internet Explorer. Support came via a small Active.

In September 2. 01. Google announced that it would phase out NPAPI support in its Google Chrome browser during 2. In May 2. 01. 4, NPAPI support was removed from the Linux version of Chrome 3. In April 2. 01. 5, Chrome for Windows and OS X versions 4. NPAPI support by default. However, until September 2. NPAPI. Opera dropped support with version 3.
