Guys believe me today I struggled a lot trying to do a very simple thing: Validating an xml file with my XSD( XML Schema), using a SAX parser(apache). I tried simple standalone program and in one shot I got itworking and now I want it to inside my web application. I added it(XSD)to the resources(classpath) and deployed my app to the tomcat but unfortunately I started getting the error "cvc-elt.1: Cannot find the declaration of element 'Root'". So I started checking my input xml m the XSD and all. All is well formed and Root is there. Then question remains where I went wrong. After some observation I found that the parser(com.sun.org.apache.xerces.internal.parsers.SAXParser) not able to get the XSD itself :( . I checked my project structure and but all things are at place. So I started putting the XSD in possible locations where this guy will look. But no luck. By now I'm pretty sure that culprit is not the directory structure. After some internet search I found thatparser properties value should be URL but I didn't want the XSD to be publicly available. Unfortunately, I didn't find how to do that directly on the Internet. So after trying things ,I came to know that which I didn't knew earlier the simple thing I missed it is that JAVA can generate an URL pointing to a file residing in the classpath. so here's the code :

SAXBuilder builder = new SAXBuilder("com.sun.org.apache.xerces.internal.parsers.SAXParser",true);
builder.setFeature("http://xml.org/sax/features/validation", true);
builder.setFeature("http://apache.org/xml/features/validation/schema",true);
builder.setFeature("http://apache.org/xml/features/validation/schema-full-checking", true);
Properties properties = new Properties();
properties.load(getClass().getResourceAsStream("/my.properties"));
URL schemaUrl = getClass().getResource(properties.getProperty("my.xsd"));
builder.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",schemaUrl);
builder.build(inXML);

If you see in my new project, there is going to be a lot of XML processing. So I was wondering what would be the better approach to parse the XML files with JAVA. After some R&D I came across a very nicely written API's for parsing the XML and you can go back and forth to get any node since each entity in xml file has been considered as object, so no more restrictions.Yes, I am talking about JDOM. It also comes with very good utility class to process xml using XPath. The static methods provided by class org.jdom.xpath.XPath are pretty straight forward and simple to use in one line :

Listlist = XPath.selectNodes(context, "//root"); 
Object obj = XPath.selectSingleNode(context, "//root"); 

java.lang.NoClassDefFoundError: org/jaxen/JaxenException ... 

XSLT template to remove empty attributes from the xml.

<xsl:template match="/">
  <xsl:copy>
     <xsl:apply-templates>
       <xsl:for-each select="@*">
          <xsl:if test=".!=''">
             <xsl:copy-of select="." />
          </xsl:if>
       </xsl:for-each>
     </xsl:apply-templates>
   </xsl:copy> 
</xsl:template>

XSLT template to reorder the elements as per the position. The order option allows you to decide the order of sort. Depending on the select XPath query result data-type can be given.

<xsl:template match="*">
    <xsl:copy>
       <xsl:apply-templates>
          <xsl:sort select="position()"order="descending" data-type="number" />
       </xsl:apply-templates>
     </xsl:copy>
  </xsl:template>

XSLT template to just copy all elements without any condition from one file to another.

<xsl:template match="* | @*">
           <xsl:copy>
              <xsl:copy-of select="@*" />
              <xsl:apply-templates />
           </xsl:copy>
        </xsl:template>

As I am new to XSLT wanted to perform some xsl transformation on my xml file and generate the xml. But when I were looking for some example how to do it I was getting all example who teach you how to transform an xml to html. So here is the way I found after some web search. Look at the tag <xsl:output> and its method just set it to xml as below. The code snippet to just copy all the elements and attributes from one xml file to another. If you want to perform some operations or checks you are free to add new templates.

<xsl:stylesheet version='1.0' 
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'> 

<xsl:output method='xml' indent='yes' /> 

<!-- copy all elements which don't match any template --> 
  <xsl:template match="* | @*"> 
    <xsl:copy> 
       <xsl:copy-of select="@*" /> 
       <xsl:apply-templates /> 
    </xsl:copy> 
  </xsl:template> 
</xsl:stylesheet>

There are few libraries out there:

•Transmorph: Transmorph is a free java library used to convert a Java object of one type into an object of another type (with another signature, possibly parameterized).

•EZMorph: EZMorph is simple java library for transforming an Object to another Object. It supports transformations for primitives and Objects, for multidimensional arrays and transformations with DynaBeans

•Commons-BeanUtils: ConvertUtils -> Utility methods for converting String scalar values to objects of the specified Class, String arrays to arrays of the specified Class.

•Commons-Lang: ArrayUtils -> Operations on arrays, primitive arrays (like int[]) and primitive wrapper arrays (like Integer[]).

•Commons-Convert: Commons-Convert aims to provide a single library dedicated to the task of converting an object of one type to another. The first stage will focus on Object to String and String to Object conversions.

•Morph: Morph is a Java framework that eases the internal interoperability of an application. As information flows through an application, it undergoes multiple transformations. Morph provides a standard way to implement these transformations.

•Lorentz: Lorentz is a generic object-to-object conversion framework. It provides a simple API to convert a Java objects of one type into an object of another type. (seems dead)

•Spring framework: Spring has an excellent support for PropertyEditors, that can also be used to transform Objects to/from Strings.

•Dozer: Dozer is a powerful, yet simple Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types.

•OTOM: With OTOM, you can copy any data from any object to any other object. The possibilities are endless. Welcome to "Autumn".

•Smooks: The Smooks JavaBean Cartridge allows you to create and populate Java objects from your message data (i.e. bind data to) (suggested by superfilin in comments).

Transmorph (pretty recent), EZMorph, Dozer, OTOM are all serious candidates. Dozer seems to be the most active project though (and maybe the most advanced). I personally used Dozer and happy with it. (list from Pascal Thivent)

Hello, We have two tables Family and Member, the relation between these two is Family has set of members in it but member don't have any family relationship within it.

I wanted get member using dob and family for that I am using Hibernate criteria API's but I am not getting how to write join query since members don't have Family instance with it. So not able to use FetchMode. Any other way to achieve this ?

Ans:

DetachedCriteria subquery = DetachedCriteria.forClass(Family.class, "family")
.add(Expression.eq("family.id", family.getId()));

subquery.createAlias("members", "members")
.add(Restrictions.eqProperty("members.id", "m.id"))
.add(Expression.eq("members.DOB",Date));

subquery.setProjection(Property.forName("members.id"));

Criteria crit = session.createCriteria(Member.class, "m")
.add(Subqueries.propertyIn("m.id", subquery));

results = crit.list();

This can be achieved using options such as using different profiles for both and another is by setting JUnit property true for surefire plug in.

Run "mvn test". Only the TestNG test will run since as soon as the maven founds the TestNG dependency in main profile it executes TestNG tests only. If you modify the pom to set the property "junit=true", only the JUnit test will run.

Hello,

I'm trying to use the @Test(expected = RuntimeException.class) annotation in order to test for an expected exception. My code is as follows:

@Test(expected = RuntimeException.class)
public void testSaveThrowsRuntimeException(){

User user = domain.save(null);

}

public User save(User newUser) {
if(newUser == null) {
throw new RuntimeException();
}
//saving code goes here
}
