Using ANT to build j2ee tutorial examples

[Mary Taylor]

At java.sun.com/xml, Sun says that j2sdkee1.3.1 supports JAXP. Yet I am getting the following error with j2ee.jar included in my CLASSPATH.
C:\j2eetutorial\examples>set CLASSPATH
CLASSPATH=C:.;C:\J2sdk331.3\lib\j2ee.jar;c:\ant\jakarta-ant-1.3\lib\ant.jar
C:\j2eetutorial\examples>ant all
The system cannot find the path specified.
Buildfile: build.xml
BUILD FAILED
No JAXP compliant XML parser found. See http://java.sun.com/xml for the

Thanks for your help.
12/12/01 I saw that the SaxParserFactory is in the j2ee.jar which is in my CLASSPATH as shown above. What am I missing?

I know cross posting to other forums is frowned upon so could someone here provide some direction for answers to my questions? I really want to work through the J2EE tutorial and not get bogged down with building the examples with ANT.
Thanks.

I include my complete set of environment variables here below. Note the error message I am receiving and that JAVA_HOME IS set to C:\jdk1.3.1. Sun gives such simple directions for building the j2eetutorial\examples with ANT at http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/J2eeTutorialPreface.html

I do not know what path the system is not able to find or if that is causing the problem. Maybe I need to spend a week learning enough about ANT to build the examples for the j2eetutorial...

You need to get JAXP from Sun, the SAXParserFactory you see ine j2see isn't the correct one. Ensure you get all the packages required for the tutorial and include all the jars in your classpath. This should allow everything to work properly.

I Hope This Helps

Carl,
Thanks for the suggestion. I looked on Sun's site for the JAXP download with no success. Did you notice that I am not now getting that error, but, rather , one related to the JAVA_HOME? The new information is in the third or forth email in this thread.
It doesn't appear JAXP is still the problem, but if you think so, then can you suggest where I can find it?
Thanks,
Betty

I checked Sun's Forums tonight and found my error. ANT_HOME mjst be set to c:\ant\jakarta-ant-1.3 and not simply c:\ant.
Thanks to all who offered assistance.

Betty,
Glad to see you worked it out. I found this link on the Sun website, you might want to run through some of these code camps:
http://www.sun.com/developers/edu/camps/
Good luck!

Thanks for the link. I'm busy doing the Forte tutorial right now. And I'm now able to continue with the Getting Started section of the J2EE tutorial. Coding is not my problem; it is setting up environments usually.
