Java Null pointer exception thrown in XSLTransform
--------------------------------------------------
Key: XALANJ-2038
URL: http://issues.apache.org/jira/browse/XALANJ-2038
Project: XalanJ2
Type: Bug
Components: Xalan
Versions: 2.6
Environment: P 4.0 Windows XP pro
Reporter: Win
When using an XSLTransformer class to transform xml data, NullPointEXception is
thrown for xsl for the following data and xsl files. The test can be run as:
\j2sdk1.4.2_05\bin\java.exe -classpath
.;.\lib\xml-apis.jar;.\lib\xercesImpl.jar;.\lib\xalan.jar
org.apache.xalan.xslt.Process -in data.xml -xsl transform.xsl -out a1.html
(It will through a null pointer exception when called from the java api
XSLTransfomer.transform as well). These same file will transform correctly with
other tools such as XMLSpy or Microsoft's
Here are the data.xml and transform.xsl files:
data.xml::
