XMLInputFactory xmlInputFactory = XMLInputFactory. The following Java API shows the main methods for reading XML in the cursor approach. StAX has its roots in a number of incompatible pull APIs for XML, most notably XMLPULL, the authors of which (Stefan Haustein and Aleksander Slominski) collaborated with, amongst others, BEA Systems, Oracle, Sun and James Clark. ![]() ![]() This is different from an event based API - such as SAX - which 'pushes' data to the application - requiring the application to maintain state between events as necessary to keep track of location within the document. The application moves the cursor forward - 'pulling' the information from the parser as it needs. In the StAX metaphor, the programmatic entry point is a cursor that represents a point within the document. StAX was designed as a median between these two opposites. A tree based API allows unlimited, random access and manipulation, while an event based API is a 'one shot' pass through the source document. These two access metaphors can be thought of as polar opposites. event based - the application registers to receive events as entities are encountered within the source document.īoth have advantages: DOM, for example, allows for random access to the document, and event driven algorithm like SAX has a small memory footprint and is typically much faster.DOM based - the entire document is read into memory as a tree structure for random access by the calling application.A sample project to develop REST API to work with Facebook PRESTO & Hive & S3.Streaming API for XML ( StAX) is an application programming interface ( API) to read and write XML documents, originating from the Java programming language community. ![]() A sample project to develop REST API to work with Amazon ATHENA & S3.The complete end-to-end sample project with Jersey + Jetty.The complete dependency configuration (Jersey + Jetty + Maven) : pom.xml 4.0.0 ZQueryEngine ZQE 1.0-SNAPSHOT 2.26-b03 1.11.133 9.2.14.v20151106 maven-compiler-plugin 1.8 1.8 jersey-bom $ : .Response.getResponse(Ljavax/servlet/http/HttpServletResponse )Lorg/eclipse/jetty/server/Response Sudhirs-MacBook-Pro -2:yanagishima -5.0 sudhir.pradhan$ curl -L -X GET http: //localhost:8083/presto/hello A very simple but commonly occurred exception.
