Research J2ee/xml Of Web-based Data Processing

XML(the extensible Markup Language) and J2EE(Java 2 Enterprise Edition), as world-wide industry standard, have been used widely recently. When XML and J2EE are used together, it will make use of their advantages and favor their development strongly.Given in this paper, through analyzing the framework of J2EE, there are three applications of XML in J2EE, such as data description and exchange, data present and message-oriented distributed computing. In the FACE project, we use XML and J2EE to implement the exchange of XML document and relation database. In addition,this paper proposes us a fine-grained access control algorithm for XML documents, which may protect the resource of XML documents.
