Daniel Kulp updated WSCOMMONS-358:
----------------------------------
Attachment: (was: xmlschema-361.patch2)
> DOM level 3 checks don't work properly
> --------------------------------------
>
> Key: WSCOMMONS-358
> URL: https://issues.apache.org/jira/browse/WSCOMMONS-358
> Project: WS-Commons
> Issue Type: Bug
> Components: XmlSchema
> Reporter: Daniel Kulp
>
> In DOMUtils, there are methods like:
> public static String getInputEncoding(Document doc) {
> try {
> Method m = Document.class.getMethod("getInputEncoding", new
> Class[]{});
> return (String) m.invoke(doc, new Object[]{});
> } catch (Exception e) {
> return DEFAULT_ENCODING;
> }
> }
> which supposedly check if it's a DOM level 3 thing or not. However, that
> only checks if the API jar is DOM level 3. It doesn't check the actual
> implementation. If you end up with the level 3 api jar, but an older
> xerces, the Method is found on the Document class, but when invoke is called,
> it gets:
> ava.lang.AbstractMethodError:
> weblogic.apache.xerces.dom.DeferredDocumentImpl.getInputEncoding()Ljava/lang/String;
> at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
> at
> sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
> at
> sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
> at java.lang.reflect.Method.invoke(Method.java:585)
> at
> org.apache.ws.commons.schema.utils.DOMUtil.getInputEncoding(DOMUtil.java:602)
> Most likely, the catch Exception should be changed to Throwable, but it might
> be good to change:
> Method m = Document.class.getMethod("getInputEncoding", new Class[]{});
> to
> Method m = doc.getClass().getMethod("getInputEncoding", new Class[]{});
> to get the method off the actual implementation class.
