Big Picture
For JRE 1.5, Sun has included with the JRE new, standardized versions of the XML APIs supporting DOM Level 3 and JAXP 1.3. These APIs are available for JRE 1.4 via jars that can be downloaded and installed into JRE 1.4.
uPortal 2.5 will standardize upon and use the APIs.
What specific APIs are we talking about
They are the APIs and implementation .jars included in JRE 1.5 (J2SE 5) and distributed at Java.net for use in JRE 1.3 and JRE 1.4. uPortal 2.5 requires JRE 1.4 or later and so we aren't particularly concerned with how to make these APIs available in JRE 1.3.
The JAXP 1.3 standalone release includes:
- dom.jar
- jaxp-api.jar
- sax.jar
- xalan.jar
- xercesImpl.jar
What about our legacy APIs?
IPortalDocument, PortalDcoumentImpl, and the uPortal DocumentFactory API become formally deprecated by this change. Instead, code using XML functionality in uPortal 2.5 is encouraged to move to use the new standard XML APIs.
