Xmlbean Vs JAXB

As we know JAXB is used for XML binding with Java. Also Apache XmlBeans also used to XML binding with JAVA. Here I am going to say (Prove) which best to use?

JAXB
Advantages:
  1. Sun's Implementation
  2. well known with JAX-WS & JAX-RPC
Disadvantages:
  1. To Marshall & UnMarshall we to write manual code.
XmlBean
Advantages:
  1. No need to write code to Marshall & UnMarshall
  2. Inbuilt support for Saxon xQuery & XPath
  3. All Bea products using (Weblogic Portal, Aqualogic Service Bus)
Disadvantages:
  1. Not known by many developers
JAXB sample code to bind XML:

public class Main {

public static void main(String[] args) {

Object pud = unmarshall(some.pkg", TestDocument.class);

marshall("poc.act.cms.poc", pud);

}

public static void marshall(String namesapce, Object object) {

try {

JAXBContext jc = JAXBContext.newInstance(namesapce);

Marshaller m = jc.createMarshaller();

m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);

m.marshal(object, System.out);

} catch (Exception e) {

e.printStackTrace();

}

}

public static Object unmarshall(String namesapce, Object object) {

try {

JAXBContext jc = JAXBContext.newInstance(namesapce);

Unmarshaller m = jc.createUnmarshaller();

return m.unmarshal(new File("xmlfile.xml"));

} catch (Exception e) {

e.printStackTrace();

}

return null;

}

}

XmlBean Sample code:

public class Main {

public static void main(String[] args) {

try {

TestDocument pud = TestDocument.Factory.parse(new File("xmlfile.xml"));

System.out.println(pud); // this will print as string

} catch (XmlException ex) {

Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);

} catch (IOException ex) {

Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);

}

}

}


as you seen by code itself XmlBean is very small.




Here is report from netbeans profiler for both JAXB & Xmlbeans to parse 10,000 rows XML file. JAXB taken 30+ seconds, where XmlBeans taken 17+ seconds.

Running and debugging jetty maven plugin in Netbeans

Coding with Netbeans will make developer life simple. We don't need search for plugins and install different plugins from different places. Maven projects can opened as directly in Netbeans without any settings. Here is the way to run & debug using maven jetty plugin. We can't add Jetty server as servers in Netbeans. Run project: Right click on project and open the properties. click on "Actions" on left side. On right side there will be list of available actions.  To run jetty can be created a new action or override default "Run Project" Here I am overriding default one, Because I can run the project just by hitting "F6" key click on "Run Project" Enter the value "Execute Goals" as "jetty:run", If you want run as offline add "jetty:run -o" "Active Profiles" can be empty In "set Properties" field we can set like skip test. Here I am skipping test. Done, After setting y

remove(unset) property in a property file using ANT PropertyFile task

Using PropertyFile task we can edit the property file during ANT build. Edit property value are very easy and can find here details. http://ant.apache.org/manual/Tasks/propertyfile.html but delete a property or comment a property is the tricky one. If we are using latest ant version (1.8.1 or later), we can delete a property like below. <propertyfile file="my.properties" comment="My properties">   < entry  key="propertykey" operation="del"/> < /propertyfile> but the older version that is before 1.8.1 don't have operation called " del ", if we run the command in lower version ant, we will get a error says undefined operation "del".      there is workaround instead deleting a property we can comment that property using ant's replace command. < replace file="sample.properties">                      < replacefilter token="propertykey" value="#propert

Disable hibernate Optimistic Lock for specific scenario

Optimistic Lock gives more control on concurrent modification on data. That can be achieved very easily in hibernate using @Version column. But in some cases we may have to avoid concurrency check, example background process. To disable Optimistic lock set OptimisticLockMode as NONE for entity class while hibernate is initiating. We can't remove version column that needs Database changes and ORM changes. In this way we can disable Optimistic Lock by code. implement "org.hibernate.event.Initializable" interface override the below method.     @Override     public void initialize(Configuration cfg) {         Iterator<?> persistentClassIterator = cfg.getClassMappings();         while (persistentClassIterator.hasNext()) {             PersistentClass persistentClass = PersistentClass.class.cast(persistentClassIterator.next());                     Iterator propertyIterator = persistentClass.getDeclaredPropertyIterator();                    while (proper
