Java EE (Java Enterprise Edition) General Discussion

Hello,

I am having problems combining xml schemas from different namespaces, and then
parsing instance documents. Any help would be super!

Firstly I created a schema in my own namespace. I can combine several schema files
using XMLSchema include. I can easily parse my instance documents
using SAXLocalNameCount.java that comes with the WSDP. No problems so far.

At this stage I wanted to start signing and later encrypting elements. So I modified my
original schema to include

<import namespace="http://www.w3.org/2000/09/xmldsig#" schemaLocation="http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/xmldsig-core-schema.xsd" />

and

<import namespace="http://www.w3.org/2001/04/xmlenc#" schemaLocation="http://www.w3.org/TR/xmlenc-core/xenc-schema.xsd" />

I then used elements from xmldsig-core-schema.xsd and xenc-schema.xsd as needed.
I modified my instance documents by adding the new namespace support

xmlns:ds="http://www.w3.org/2000/09/xmldsig#"
xmlns:xenc="http://www.w3.org/2001/04/xmlenc#"

Again everything parsed fine using SAXLocalNameCount.java. Everything still fine!

Next I decided that I would prefer to use my local copies of the w3.org schemas rather
than contacting their site all the time. (I know that SAXLocalNameCount.java is
doing this because if I remove my proxy configuration from the java command line I
get:

Warning: URI=null Line=32: src-import.0: Failed to read imported schema document �http://www.w3.org/TR/xmlenc-core/xenc-schema.xsd�.
Exception in thread "main" org.xml.sax.SAXException: Error: URI=null Line=121: src-resolve: Cannot resolve the name 'xenc:EncryptedDataType' to a(n) type definition component. at org.apache.xerces.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1092) at SAXLocalNameCount.main(SAXLocalNameCount.java:251)

.)

So I modified SAXLocalNameCount.java as shown below (All files in the same
directory):

if (schemaSource != null)
   {
     Object[] mySchemas = new Object[3];
     mySchemas[0] = new File(schemaSource);
     mySchemas[1] = new File("xenc-schema.xsd ");
     mySchemas[2] = new File("xmldsig-core-schema.xsd");

     saxParser.setProperty(JAXP_SCHEMA_SOURCE, mySchemas);
      }

My new SAXLocalNameCount.java compiles fine. If I run it with the proxy then
everything is fine. However I still get the same exception as above when I run it
without using my proxy. This indicates to me that it is NOT using my local copy
of the schema.

Yet if I delete my local copies of xenc-schema.xsd and xmldsig-core-schema.xsd
I now get:

Exception in thread "main" org.xml.sax.SAXException: Error: URI=file:/D:/temp/TLSML/t/tlsml3.xml Line=4: schema_reference.4: Failed to read schema document 'xenc-schema.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. at org.apache.xerces.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1092) at SAXLocalNameCount.main(SAXLocalNameCount.java:261)

So it appears that I now need both my local copy, and the remote copy!

I am certain that I must be making some small mistake. My files are all listed below.
Any help would be greatly
appreciated!

Thanks!
