XML validation using XMLbeans

XML file validation is somewhat painful job. If we have XML Schema(XSD) that can be done very easily using Apache XmlBean. Also traversing or parsing XML will be joyful with XmlBean.

First we have to generate Java class for XSD using XmlBean's scomp command, this can be done in command line. there are some options to generate source only or only Jar file.

After having Xmlbean objects for XSD, parsing and validating can be done like below:



void validate(String fileName) {
        XmlDocument xmlObject = XmlDocument.Factory.parse(new File(fileName)); //parse the XML file
        ArrayList validationErrors = new ArrayList(); 
        XmlOptions validationOptions = new XmlOptions(); 
        validationOptions.setErrorListener(validationErrors); 
        boolean isValid = xmlObject.validate(validationOptions); // to display error we should pass options.
        if (!isValid) {
            for (XmlValidationError es : validationErrors) {
                System.err.println(es);
            }
        }
    }

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
