NoSuchMethod: Xerces: Augmentations.clear()V

[Mats Henricson]

I've started to get these wird errors with HttpUnit the last few weeks. It bombs in the constructor to WebConversation! What I've done lately is migrating all my pages and code to UTF-8. It works just fine, but my HttpUnit tests are now failing... :-)

Anyone with a clue?

I am new to Httpunit and trying to implement my first test case using it. I am getting the same error and I'm at a loss.

I've seen this when my tests were deployed with a different version of xerces than what httpunit 1.5.4 was packaged with.

I recently started a new project and used the xerces parser that comes with the latest version of HttpUnit and for some reason I get the same error as above...

"org.apache.xerces.xni.Augmentations.clear()V"

I get this error when calling WebResponse>>getTitle() (obviously trying to use the parser services).

My work around was to ditch xerces and just use the Tidy.jar parser. However I would like an answer why xerces does not work ?

Get the source for nekohtml.jar ver 0.7.2 and update src/html/org/cyberneko/htmlHTMLScanner.java class's locationAugs()  method. Instead of augs.clear(); line
add try {
                augs.clear();
            }
            catch (NoSuchMethodError e) {
                augs.removeItem(AUGMENTATIONS);
            }
and rebuild nekohtml.jar with the changes  in jdk 1.3 and use this jar in httpunit. Tests works fine
