Re: WSAD - Getting to know Xalan-J version
Posted by Yash Talwar <yt...@ca.ibm.com>.
Hi Mukul,
In WSAD 5.1.2, when you start WebSphere Test Environment for base_v5 (WTE
5), another jvm is started for WTE. WebSphere 5 starts in this jvm and load
the jar files that are located in lib directory.
Then, you publish the servlet application on WTE and invoke the servlet.
When servlet is invoked, JVM finds the xalan specific classes with
libraries that are loaded for WTE.
You can pick up your own copy of xalan.jar in the classpath. However, this
information is in scope of usage of WebSphere and not xalan. For this
information, please have a look at WAS Info center for version 5. I
bellieve there are properties such as PARENT_FIRST / PARENT_LAST in
WebSphere that you can set in order to pick up your own copy of xalan.jar
before WTE libraries are picked. Even WSAD help section should have this
information.
I hope this helps!
Thanks!

Please respond to version
Mukul Gandhi
Thank you for reply. I'll check it.. In my WSAD installation, there is
xalan.jar at location E:\Program Files\IBM\WebSphere
Studio\runtimes\base_v5\lib. So Xalan is bundled with WSAD. It seem to
be hooked to JAXP internally. But how? Is there some IBM JRE
configuration file somewhere? I also have another xalan.jar(for
Xalan-j 2.6.0) in CLASSPATH which is the latest distributable from
Apache's site http://xml.apache.org.
I am thinking how can I use both Xalans to work simultaneously on my
PC. Any ideas please?

You can try invoking the org.apache.xalan.Version class. If it's a
copy of Xalan-J that's included with the IBM JRE, the name will be XSLT4J.
The version number of XSLT4J has a rough correspondence with that of
Xalan-J, but the two are not entirely identical.
Thanks,
Henry

WSAD - Getting to know Xalan-J version
Posted by Mukul Gandhi <ga...@gmail.com>.
Sorry if this question is off-topic. I am developing a JAXP(using TrAX
API) application in WSAD 5.1.2. I have actually written a Servlet
which does XSLT transformation using TrAX API. I am successfully
getting the transformation result on the browser.
I believe IBM JRE and Xalan-J is being used behind the scenes. I am
interested to know which version of Xalan-J is being used. How can I
find this information?

Mukul

It requests that the processor perform some optimization of the
instructions in an XSLT stylesheet - for example, looking for
subexpressions that are common to more than one expression and evaluated
with respect to the same context, and so can be evaluated just once.

OK thanks very much for your answers. I thought that DTM was *just* an
optimization.
I had not understood that it was rather an in-depth implementation choice.
By the way what's the meaning of
"http://apache.org/xalan/features/optimize" then ?
Thanks again

If you're asking for a way to use the XPath API of Xalan-J without
using DTM, it's not possible without rewriting large parts of the
processor; the implementation of XPath and XSLT in Xalan-J is built upon
DTM.
Joseph Kesselman did some work on a revised DTM implementation over
DOM which, if I recall correctly, does not rely on a DOM node to be always
the same Java object, but I don't believe that work was ever completed. If
you're interested, you can take a look at the code in the xslt20 branch of
the xml-xalan project, in the org.apache.xml.dtm.dom2dtm2 package.
Thanks,
Henry
