xml-apis dependency
Hi,
Let me preface this by saying that I'm sure this has been answered
somewhere, but I searched the list archives and read what the Xalan J
documentation.
Is the xml-apis.jar still a dependency when running in Java 1.5? Seems
like the JAXP classes that are needed come with the JVM now. Are there
other things outside the JAXP 1.3 spec that are provided in this xml-
apis.jar that I need?
I have an application with Xalan running it already and I know that it
does not have any problem, compiling or deploying so far without xml-
apis.jar in there. I've also tried some basic transformations.
Thanks,
Bradley

Further, if you do want to use improved versions, I
suspect you have to use "endorsed" mechanism.
Otherwise JDK-bundled classes tend to get preference
over other jars. Unless rules are different for
extensions (javax.*)?
(same won't apply to the API implementation itself
which gets introspected correctly as JDK-included
version lives under different package)

The xml-apis I have came bundled with JBoss 3.2.7 (admittedly ancient)
and uses the JAXP 1.2 spec as per the JAR's manifest file.
I don't see an org.w3c.dom.xpath package in either my 1.5 JRE classes
or this xml-apis JAR. I do see a org.w3c.dom.xpath package in my Xalan
2.6 JAR but those interfaces don't appear to extend anything that's
not present in my JRE.
It seems to me that the xml-apis I am using is so old that the 1.5 JRE
version of these APIs would preferable anyway.

Now that I think of it there are several APIs (org.w3c.dom.xpath for
example) bundled in xml-apis.jar which are not included in the JAXP 1.3
specification (and by extension Java 5) that Xerces and Xalan depend on.
Sun may have shipped them but there's no guarantee that they'll be there.
Thanks.

Thanks for the quick response. If I understand you correctly, xml-apis
is an improvement rather than a true requirement when running with
Java 5.0.
All of the interfaces, classes that are implemented or subclassed by
Xalan are available with Java 5 so I would not run into any class
loading (ClassNotFoundException) errrors.

Hi Bradley,
xml-apis.jar contains bug fixes (and even performance improvements) [1]
which may not be in Java 5 so you may be trading these off by not carrying
the jar with your application.
Thanks.
