when do you need these jars: resolver.jar,etc..
I could compile the Schema and run my Java app which
uses this schema Jar using only 3 Jars:
jsr173_1.0_api.jar xbean.jar xmlbeans-qname.jar
Why would I ever need resolver.jar and xmlpublic.jar?
I use J2SE 1.4.x

Re: how to get jdom Document from XmlObject efficiently?
Posted by Jacob Danner <ja...@gmail.com>.
AFAIK there isn't a convenience API to go from XmlObject to JDom Document.
However, you can go from XmlObject to org.w3c.dom Node Object using
XmlObject.newDomNode(). One thing to note that I particularly enjoy is that
XMLBeans provides a DOM2 Level API/Implementation so you can go seamless
from
DOM <-> XmlCursor <-> XmlObject
Once this feature was implemented I stopped using JDom, but I'm sure there
is some kind of convenience method to go from org.w3c DOM to JDom.
Best of luck,

I have an XmlObject type document object produced out
of XmlBeans processing. What is efficient way to
convert this XmlObject type to org.jdom.Document ?
Thanks

Re: how stable is xpath handling in XMLBeans (even a basic expression fails with RunTimeException)
Posted by Jacob Danner <ja...@gmail.com>.
I've always viewed Xpath as a subset of XQuery.
When the statements get too complex for xmlbeans to handle internally, it
delegates to the available engine to process. This way XMLBeans does not
need to implement an internal xpath engine, but rather can piggy back off
the richer, fuller feature set of xquery.
The xbean_xpath.jar is the hookup between xmlbeans and the xquery engine. In
the 1.x release, it provided the hookup to jaxen. In the 2.x release, it
provides the hookup for saxon.

As per documentation, saxon is required for XQuery. Am
only using Xpath. To my understanding, I only need
xbean_xpath.jar in addition to regular Jars to do some
complex(like predicates,etc) Xpath processing.

Re: how stable is xpath handling in XMLBeans (even a basic expression fails with RunTimeException)
Posted by Jacob Danner <ja...@gmail.com>.
Do you have saxon8.jar in your classpath when executing these xpath
statements? It doesn't look like thats the case.
The way XMLBeans handles xpath is to look to see if it can handle the
statement internally, and then it looks for available engines on the
classpath. It appears to fail when trying to find Saxon. If you don't think
this is the case, can you post the whole stacktrace?
There is a blurb about Saxon on the website under the 2.3 release news

how stable is xpath handling in XMLBeans (even a basic expression fails with RunTimeException)
Posted by dave <ce...@yahoo.com>.
I was just trying to use count() funtion in a simple
Xpath expression and I get this RuntimeException :
Exception in thread "main"
java.lang.RuntimeException: Trying XBeans path
engine... Trying XQRL... Trying Saxon... FAILED on
declare namespace ns=....
I see numerous postings from others who had the
similar issue and there are no responses indicating
any specific solution. Before I waste some more time
on this, I just wanted to know if it's even worth
using XPath support in XmlBeans.
Here's my env:
xmlbeans 2.3.0 + all the latest Jars in classpath.
The expression having issue:
"count($this/ns:root/ns:owners/ns:owner)"
I also tried the following but has the similar issue:
"count(//ns:owners/ns:owner)"
Tried getting all the owner elements (Still the same
issue):
"$this//ns:owners/ns:owner"
But this works: "$this/ns:root/ns:owners/ns:owner"
any clues to get this simple crap working!!
OR should I switch to Jdom for Xpath processing?

Classes in xmlpublic.jar are contained in xbean.jar. xmlpublic.jar can
be used for java compilation to make sure an application is not using
any private unsupported APIs.

i found that resolver.jar s required when catalog is
