J2se 5.0 and EnvironmentCheck not working - works with JDK 1.4.x however 2006-06-01 - By John Lukar
Kevin,
thanks for the response.
My underestanding was that the xalan, xerces and jaxp are all roled
into the JDK 1.5 and hence no need for me to add them to the
classpath.
from 1.5 release notes at:
http://java.sun.com/j2se/1.5.0/docs/guide/xml/jaxp/ReleaseNotes_150.html
#versions
" Component Versions
These versions of the relevant technologies have been incorporated
into the reference implementation.
* Xerces version 2.6.2 + (Xerces version 2.6.2 with controlled bug fixes)
* XSLTC version 2.6.0 + (XSLTC version 2.6.0 , with controlled bug
fixes, based on the Xalan 2.6.0 release) "
so thats where I am comming from.
I unjared the rt.jar and noticed bunch of xalan and xerces packages
prefixed with com/sun/....
so I assumed that they have roled them into rt.jar that is part of the JDK 1.5
the echo $CLASSPATH for JDK 1.4 is empty and hence there are no extra
jars related to xalan/xerces that are in the classpath as well and yet
that works.
running the command in jdk 1.4.2 is successfull as below:
[me@(protected):/opt/j2sdk1.4.2_06/bin] ./java
org.apache.xalan.xslt.EnvironmentCheck

# YAHOO! Your environment seems to be OK.
running the command in Jdk 1.5 is not successfull:
[me@(protected):/opt/jdk1.5.0_07/bin] java
org.apache.xalan.internal.xslt.EnvironmentCheck
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/xalan/internal/xslt/EnvironmentCheck
I can put the xalan.jar and et al in the classpath and try but I was
hoping I could simply use what is in JDK.
help.
