http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13214 Nexted xs:import statements do not work correctly. Summary: Nexted xs:import statements do not work correctly. Product: Axis Version: 1.0-rc2 Platform: All OS/Version: Other Status: NEW Severity: Blocker Priority: Other Component: WSDL processing AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Axis RC2 has a bug that causes nested xs:import statements to work incorrectly.

Thus the following statement in schema2.xsd causes Axis to look for schema3 in directory1, not directory 2: <xs:import namespace="http://www.test.com"; schemaLocation="schema3.xsd"/> Fixing this bug is easy – it requires updating the SymbolTable.LookForImports method in Axis and then rebuilding Axis. The fix is: private void lookForImports(URL context, Node node) throws IOException { NodeList children = node.getChildNodes(); for (int i = 0; i < children.getLength(); i++) { Node child = children.item(i); if ("import".equals(child.getLocalName())) { NamedNodeMap attributes = child.getAttributes(); Node namespace = attributes.getNamedItem("namespace"); // skip XSD import of soap encoding if (namespace != null && Constants.isSOAP_ENC(namespace.getNodeValue())) { continue; } Node importFile = attributes.getNamedItem("schemaLocation"); if (importFile != null) { URL url = getURL(context, importFile.getNodeValue()); if (!importedFiles.contains(url)) { importedFiles.add(url); String filename = url.toString(); // This is NOT correct. The correct path is // given by URL, not the original context // populate(context, null, // XMLUtils.newDocument(filename), // filename); // This is the correct call. populate(url, null, XMLUtils.newDocument(filename), filename); } } } lookForImports(context, child); } } // lookForImports
