Re: [castor-dev] Using a different DTD

Shelly,

In the main method below you have a CFXMLResolver class static method. Can
you send the implementation to this please

Thanks

One way is to create your own EntityResolver which will override the dtd
reference with another registered reference, and pass this entity resolver
to the Mapping Object while loading the mapping. Here's an example of an
entity resolver which will load the dtd from the classpath. 



import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;

import org.w3c.dom.Document;
import org.xml.sax.EntityResolver;
import org.xml.sax.InputSource;

public class CfClasspathEntityResolver implements EntityResolver{
        private static final CfClasspathEntityResolver THIS=new
CfClasspathEntityResolver();
        private Map dtdMap;
        /**
         * constructor made private to 
         * enforce singleton
         */
        private CfClasspathEntityResolver(){
                dtdMap=new HashMap();
                registerDefaultReferences();
        }
        


        /**
         * register the defaults dtd references here
         * for key use the public id and for the value use
         * the classpath relative location
         */
        private void registerDefaultReferences(){
                
                
                
        }
        
        /**
         * register a new entity reference
         * for key use the public id and for the value use
         * the classpath relative location
         */
        public void registerReference(String publicId, String location){
                dtdMap.put(publicId,location);
        }
        
        /**
         * implement resolve entity method from super class
         */
        public InputSource resolveEntity(String publicId, String systemId){
                        String dtdURL = null;
                if (publicId != null){
                        //find the registered dtd url
                dtdURL = (String) dtdMap.get(publicId);
                }
                        if (dtdURL == null) 
                        {
                                return null;
                        }
                        InputStream
stream=this.getClass().getClassLoader().getResourceAsStream(dtdURL);
            return (new InputSource(stream));
       

                }
        public static CfClasspathEntityResolver getInstance(){
                return THIS;
        }
        
        /////////////////////////////example
usage/////////////////////////////
        public static void main(String args[])throws Exception{
                CfClasspathEntityResolver
resolve=CfClasspathEntityResolver.getInstance();
                resolve.registerReference("-//Sun Microsystems, Inc.//DTD
Web Application 2.2//EN", "web-app_2_2.dtd");
                Document
doc=CfXMLHelper.getDocumentFromFile("C:\\WSAD\\workspace\\WarrantyTestWeb\\w
ebApplication\\WEB-INF\\web.xml",resolve,true);
                System.out.println(CfXMLHelper.getStringFromDocument(doc));
        }
}

Subject: [castor-dev] Using a different DTD


Hi,

Does anyone know how to reference the DTD within the docType tag of the
mapping.xml file from within a jar.

for example:  the mapping xml file references the following dtd
file:///D:/castor/castor-0.9.3.21/castor-0.9.3.21/doc/mapping.dtd .  However
I am planning on deploying this to an application server and other people
will want to use this mapping.xml  They will not neccessarily have this dtd
in the same location as mine.  Thus is it possible to put this mapping.dtd
within the jar file which is deployed onto the application server.  

How would I reference the dtd if it was within the same jar file as the
mapping.xml file?

All helpis greatly apprecited
Thanks
Faisal
