Hi,
I am currently evaluating whether the Xalan dependency can be dropped
from taglibs and replaced with javax.xml.*.
The reason for this is a conflict which occurs when I have Apache Fop as
a dependency:
java.lang.ClassCastException: org.apache.xml.dtm.ref.DTMManagerDefault
cannot be cast to org.apache.xml.dtm.DTMManager
at org.apache.xml.dtm.DTMManager.newInstance(DTMManager.java:137)
at org.apache.xpath.XPathContext.<init>(XPathContext.java:102)
at org.apache.xpath.XPathContext.<init>(XPathContext.java:349)
at org.apache.xpath.XPathContext.<init>(XPathContext.java:337)
at
org.apache.xalan.transformer.TransformerImpl.<init>(TransformerImpl.java:397)
at
org.apache.xalan.templates.StylesheetRoot.newTransformer(StylesheetRoot.java:200)
In org.apache.taglibs.standard.tag.common.xml it seems like
org.apache.xpath.XPath could be replaced with
javax.xml.xpath.XPathExpression.
But the thing I don't understand is the method getContext in
org.apache.taglibs.standard.tag.common.xml.XalanUtil uses a
VariableStack and returns an XPathContext. I am not sure how they fit
into the SAX (?) model.
Can anyone shed some light on the inner workings of this function?
Regards,
Matthew
