    <p>In my program, I am generating a XML file, and need to validate that XML file against multiple schemas which are located on different URLs. Its required to validate that XML file against all schema in onetime only.</p> <p><strong>Source fragment:</strong></p> <pre><code>// here source array contain the locations of schemas, located at diff servers. Source[] source = { new StreamSource( new URL("http://localhost:8081/test1/testSchema1.xsd") .openStream()), new StreamSource( new URL( "http://ccr.internal.ericsson.com/test2/testSchema2.xsd") .openStream()) }; try { // Compile the schema, which loaded from schemaFileLocation. Schema schemaGrammar = schemaFactory.newSchema(source); // Create a validator for schema. Validator configValidator = schemaGrammar.newValidator(); // set error handler with validator. SchemaValidator schemaValidator = new SchemaValidator(); configValidator .setErrorHandler(schemaValidator.new MessageHandler()); // validate xml instance against the grammar. configValidator.validate(new StreamSource(new File("xmlFile.xml"))); System.out.println("\n"); } catch (SAXException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } </code></pre> <p><strong>When I run the above code fragment, I am get this error:</strong></p> <blockquote> <p>org.xml.sax.SAXParseException: src-resolve: Cannot resolve the name 'xn:SubNetwork' to a(n) 'element declaration' component. at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source) at org.apache.xerces.util.ErrorHandlerWrapper.error(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDHandler.reportSchemaError(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDHandler.getGlobalDecl(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDElementTraverser.traverseLocal(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDElementTraverser.traverseLocal(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDAbstractParticleTraverser.traverseSeqChoice(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDAbstractParticleTraverser.traverseChoice(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDComplexTypeTraverser.processComplexContent(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDComplexTypeTraverser.traverseComplexTypeDecl(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDComplexTypeTraverser.traverseLocal(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDElementTraverser.traverseNamedElement(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDElementTraverser.traverseLocal(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDHandler.traverseLocalElements(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDHandler.parseSchema(Unknown Source) at org.apache.xerces.impl.xs.XMLSchemaLoader.loadSchema(Unknown Source) at org.apache.xerces.impl.xs.XMLSchemaLoader.loadGrammar(Unknown Source) at org.apache.xerces.impl.xs.XMLSchemaLoader.loadGrammar(Unknown Source) at org.apache.xerces.jaxp.validation.XMLSchemaFactory.newSchema(Unknown Source) at com.work.test.generateErrorLog(SchemaValidator.java:197)</p> </blockquote> <p>What is the problem in code? Is their is any other way to validate against multiple schema?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
