Description

Registered portal program communication system, communication device and method

Technical field

The invention relates to a portal system communication technology, in particular to a registered portal program

(Portlet) communication system, communication device, and method. Background of the invention

Portal is a web-based application that integrates and presents different resources to users. Enterprises can use Portal to integrate all existing applications into a unified website. Portals can achieve reasonable resources through Portal. And the content can be customized. The integration of resources in a typical portal system has three characteristics: personalization, single sign-on, and a collection of content that can be composed from different sources.

Portlet is a web-based JAVA technology that can be used as a pluggable user interface component of Portal. Portals assemble the code fragments generated by portlets into complete pages. The portlet container in which the portlet is located manages the portlet, processes the request made by the portlet, and dynamically returns the page to the portlet. Portlet communication is a very important feature in the actual application of Portal. It determines whether portlets can interact and transfer data, and also determines the scalability of the Portal system.

In the prior art, portlet data communication can be realized through a uniform resource locating address (URL), and this technical solution transmits data as a parameter to a target portlet. Therefore, the prerequisite for the implementation of this technical solution is that the target page and the target portlet must be known. However, the customizable features of the Portal system make the pages added by the user dynamically generated. Therefore, the identity of a certain page cannot be known during the development phase, and the target page and the target portlet cannot be determined, so the availability of the technical solution is not strong. In addition, the way in which data is passed through a URL has limitations on the format and size of the data. Only string data can be passed on the data format; in data size The total length of the upper URL cannot exceed 2048 characters.

Portlet data communication can also be implemented in the prior art through JAVA message service (JMS) communication technology. This solution uses JMS to send and receive messages, that is, Topic-based subscription/distribution. Although it can achieve certain communication purposes, this solution not only needs to specify the target page and target portlet, but also needs to be managed by JMS itself or based on portal. The business application itself developed by the system cannot be managed by the web container. Portal's data transfer is based on the same Hypertext Transfer Protocol (HTTP) request, which means that if the web container performs special processing on the current request, it will also affect the data being passed, such as the termination request. Or when you transfer to another page, the data passed is automatically cleared. When portlet communication is implemented using JMS communication technology, since lifecycle management cannot be managed by the web container, if the web container performs special processing on the current request, the automatic removal of the transmitted data cannot be achieved.

There are two other solutions in the prior art, one is a technical solution for implementing portlet data communication through a session, and the other is a technical solution for implementing portlet data communication through a request. In both scenarios, although the portlet communication can be implemented without specifying the target page, the two technical solutions have great hidden dangers in data security due to the unclear target page. The availability of the solution is very low.

In summary, when the communication target page, such as the portlet in the target Portal page, is uncertain, the prior art portlet communication method will lose availability or availability. In addition, the prior art portlet communication method not only has a great hidden danger in data security, but also has a large limitation on the amount of data and format in the communication process, and implements a common page to the portal by using the portlet communication method of the prior art. When pages pass data, complex intermediate operations are required, such as the need to produce URLs. Summary of the invention
