Revisiting some similar threads from several years ago... I want to use the Nu Html Checker (v.Nu) RELAX NG compact syntax schemas with Oxygen XML Author to edit XHTML5 documents. I'm using Oxygen XML Author version 15.2 on Windows 7. I'm already editing XHTML5 documents with the v.Nu schemas in another editor, jEdit, thanks to a jEdit XML plugin developer who has supplied me with a .jar containing the required datatype library. Good news: I can drop that .jar into the Oxygen lib directory, and everything "works": I point to the v.Nu schemas (that refer to a custom datatype), and Oxygen validates my XHTML5 documents. Bad news: I'm unable to re-create that datatype .jar myself, hence this email. I've cut down the release vnu.jar (which is what I believe the jEdit XML plugin developer did) to create a .jar containing just the classes (and other embedded data files) required by the datatype library (to avoid introducing classes that might clash with others in the classpath) to exactly the same set of files, and I've compared contents (including decompiling classes). I can't spot any significant differences between the two jars. But his works, mine doesn't :-(. And yet... both jars (mine and his) work in jEdit. So, I'm confused. To me, the most obvious answer is: there's something wrong with my .jar that I'm overlooking, that, for some reason, matters to Oxygen but not to jEdit (I haven't compared Jing versions in each product). Still, I have this niggling feeling that my jar might be okay, and that Oxygen has cached something to do with the custom datatypes in a way that requires the original version of the datatype .jar I used (from the jEdit XML plugin developer). I just don't know where that cache might be. I've deselected "parser caching", but I haven't seen any option to "clear parser cache". I'd appreciate advice on any of this. In particular: - Is my niggling feeling about parser caching just wishful thinking? Or is there a parser cache (that persists between Oxygen sessions) that I can clear? - Can someone provide me with steps that I can reproduce to cut down a release vnu.jar to, say, a vnu-datatype.jar that works in Oxygen?
