How to validate a xml to a xsd in this situation?


I'm developing a EJB app. The idea is that the EJB should validate a xml-stucture with a xsd.

This was working fine until I needed to put it all in a jar-file.

The structure of the ejb.jar looks like:


I populate a document build upon a xmlskeleton.
Then I would like to validate the xml-structure according to the xsd.

Before, when this was in a exploaded file structure, I could set the xsd-path as a element in the xml-structure.

But now when the xsd is inside the jar, and as you can see in the code below, the xsd-file will not be found.

So if you have any suggestions how to include the xsd for the validation from a jar please let me know!!

BTW I can just use Java 1.4

Best regards

    public boolean validateXML(String xml, String xsdFilePath, String nameSpace, String rootElementName)
        try {
            //Build temporary document
            Document documentTemp = buildDocumentFromString(xml);

            //Set namespace and schemaLocation for validation this will not concern the paths in xml sent to IC
            setXmlElementAttribute(rootElementName, "xmlns", nameSpace, documentTemp);
            setXmlElementAttribute(rootElementName, "xsi:schemaLocation",
                                   nameSpace + " " + System.getProperty("user.dir") + "/" + xsdFilePath, documentTemp);

            //Transform document to xml String
            String tempXml = getXmlStringFromDocument(documentTemp);

            //Validate the xml String
            saxParseException = null;
            SAXParser parser = new SAXParser();

            //parser.setFeature("http://xml.org/sax/features/validation", true);
            parser.setFeature("http://apache.org/xml/features/validation/schema", true);
            parser.setFeature("http://apache.org/xml/features/validation/schema-full-checking", true);
            parser.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation", xsdFilePath);
            parser.parse(new InputSource(new StringReader(tempXml)));

            if (saxParseException == null) {
                return true;
            } else {
                return false;
        } catch (Exception e) {
            printExceptionToFile("XML_EXCECPTION", e);

            return false;

i think you need to put the xsd file in the folder containing the jar file ...

because your current folder will be the folder containnig the jar, so if you put the xsd in the same folder , then you can give your xsdfilepath as your xsd file name


Thanks for your reply!

Unfortunately I do not think I can do that.

Do you know if it is possible to include the schema in the XML like you can do with old DTD:s?

Thanks for all replies.

Actually you are right when you say that I have problem with load the resource from the jar.

I have tried the following:

      parser.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation", getClass().getClassLoader().getResourceAsStream("resources/xsd/my.xsd"));

But then I get:

java.lang.ClassCastException: weblogic.utils.zip.SafeZipFileInputStream

I have scan you links but I can not find the answer. Please correcy me if I'm wrong!

But I found this at the bootom of one of your links that sound interesting. Not Exactly what I want but I will try it:

Thanks for your reply!

I use regualar SDK 1.4 and a editor and weblogic as application server.

Perhaps your links is refering to any package from weblogic that I can use to validat a xml-structure according to a xsd in a jar?

I will look at it during the day!
