Transmitting XML between different applications
Hello, I have a requirement to pass XML between 2 different applications. The 2 applications are running on different machines, and are Java based. The sender application will generate XML to be sent, and would send the XML to the receiving application. I want to know the possible approaches for this. The following two approaches are coming to my mind. 1) Create a DOM object at the sending application, and send this DOM object to the recieving application. I have some doubt with this approach.. I think, that with this approach, if XML parser being used at both applications is same, it won't be a problem. But lets say, if "Java XML parser" used by 2 applications is different (but both conform to DOM specification), will this approach work(for e.g., the sending application is using Xerces, while receiving application is using Oracle implementation)? Lets say, if I create a DOM object at the sending application using Xerces, like this - Document doc= new DocumentImpl(); Element root = doc.createElement("person"); Element item = doc.createElement("name"); etc.. Here Document is an interface (defined in package org.w3c.dom) , while DocumentImpl is a concrete class(defined in package org.apache.xerces.dom). And I send the "doc" object to the recieving application. If the receiving application is using an "Oracle Java XML parser", will it be able to parse the recieved DOM object? 2) Encode XML as string at the sending application, and send this XML string to the receiving appliction. I want to compare the above approaches from feasibility and performance point of view. I also want to know other approaches.. As a secondary requirement, I want to make the XML transmission reliable(i.e. guranteed and 1 time delivery). I belive, I can use messaging softwares for this (like WebSphere MQ and others). What are the best practices for reliable transmission? Should I pass DOM object, String.. etc.? Later, it might be possible that 2 participating applications may run on different technologies (like J2EE and .NET). What are the possible XML transmission(i.e. creation, transmission and finally consuming) techniques in this scenario? Regards, Mukul __________________________________ Do you Yahoo!? Yahoo!
