Re: Problems running example DOM3 parser creation

[csaba . szucs]

hello,

I came across the same problem recently, I guess.

I think, You have to use endorsed jar files = You have to make a folder called "endorsed" below <Your JDK home>\jre\lib and You have to put the dom jars there:
 - dom3-xml-apis.jar
- and dom3-xercesImpl.jar, as well!

See below!




Kind regards,

Csaba Szucs

Following the example, on the Programming with DOM page, for creating a
DOM3 LS parser, I get a
ClassCastException: org.apache.xerces.dom.DOMImplementationSourceImpl
    at org.w3c.dom.bootstrap.DOMImplementationRegistry.newInstance(
                                                                   DOMImplementationRegistry.java:144)

i.e. at
                DOMImplementationSource source =
                    (DOMImplementationSource) sourceClass.newInstance();

The code, taken from the example, is
      DOMImplementationRegistry registry = null;
      System.setProperty(DOMImplementationRegistry.PROPERTY,
          "org.apache.xerces.dom.DOMImplementationSourceImpl");
      try {
          registry = DOMImplementationRegistry.newInstance();
      } catch (Exception e) {
          throw new RuntimeException(e);
      }

Any idea what I'm doing wrong?

Peter

Title: Endorsed Standards Override Mechanism

Endorsed Standards Override Mechanism Documentation Contents Introduction An endorsed standard is a JavaTM API defined through a standards process other than the Java Community ProcessSM (JCPSM). Because endorsed standards are defined outside the JCP, it is anticipated that such standards may be revised between releases of the Java 2 Platform. In order to take advantage of new revisions to endorsed standards, developers and software vendors may use the Endorsed Standards Override Mechanism to provide newer versions of an endorsed standard than those included in the Java 2 Platform as released by Sun Microsystems. Endorsed Standards Classes Deployment Classes implementing newer versions of endorsed standards should be placed in JAR files. The system property java.endorsed.dirs specifies one or more directories that the Java runtime environment will search for such JAR files. If more than one directory path is specified by java.endorsed.dirs, they must be separated by File.pathSeparatorChar. If no value is set for java.endorsed.dirs, then Sun Microsystem's implementation of the Java 2 Platform looks for JAR files in a default standard location: <java-home>\lib\endorsed [Microsoft Windows] <java-home>/lib/endorsed [Solaris or Linux] Here <java-home> refers to the directory where the runtime software is installed (which is the top-level directory of the Java 2 Runtime Environment or the jre directory in the Java 2 SDK). The Java runtime environment will use classes in such JAR files to override the corresponding classes provided in the Java 2 Platform as shipped by Sun. Endorsed Standards APIs The endorsed standards for J2SETM 1.4 constitute all classes and interfaces that are defined in the packages listed below. Classes and interfaces defined in sub-packages of listed packages are not endorsed standards unless those sub-packages are themselves listed. The Endorsed Standards Override Mechanism may be used to override the J2SE platform packages in the list below, and these packages may be overriden only by versions of the endorsed standard that are newer than that provided by the Java 2 Platform as released by Sun. No other packages from the J2SE platform API specification may be overridden. javax.rmi.CORBA org.omg.CORBA org.omg.CORBA.DynAnyPackage org.omg.CORBA.ORBPackage org.omg.CORBA.portable org.omg.CORBA.TypeCodePackage org.omg.CORBA_2_3 org.omg.CORBA_2_3.portable org.omg.CosNaming org.omg.CosNaming.NamingContextExtPackage org.omg.CosNaming.NamingContextPackage org.omg.Dynamic org.omg.DynamicAny org.omg.DynamicAny.DynAnyFactoryPackage org.omg.DynamicAny.DynAnyPackage org.omg.IOP org.omg.IOP.CodecFactoryPackage org.omg.IOP.CodecPackage org.omg.Messaging org.omg.PortableInterceptor org.omg.PortableInterceptor.ORBInitInfoPackage org.omg.PortableServer org.omg.PortableServer.CurrentPackage org.omg.PortableServer.POAManagerPackage org.omg.PortableServer.POAPackage org.omg.PortableServer.portable org.omg.PortableServer.ServantLocatorPackage org.omg.SendingContext org.omg.stub.java.rmi org.w3c.dom org.xml.sax org.xml.sax.ext org.xml.sax.helpers In addition to the packages listed above, which are part of the J2SE specification, users of Sun's J2SE Reference Implementation may be allowed to use the Endorsed Standards Override Mechanism to override implementation-specific classes such as the org.w3c.dom sub-packages delivered in Sun's Reference Implementation.
