The parser problem is related to jar files , can be resolved not a bug.

this site is  down; cant see it

It is a bug, because I view all operations problems as defects to be opened in the bug tracker, stack traces stuck in, the problem resolved. That's software or hardware -because that issue DB is your searchable history of what went wrong. Given on my system I was seeing a ClassNotFoundException for loading FSConstants, there was no easy way to work out what went wrong, and its cost me a couple of days work.

furthermore, in the OSS world, every person who can't get your app to work is either going to walk away unhappy (=lost customer, lost developer and risk they compete with you), or they are going to get on the email list and ask questions, questions which may get answered, but it will cost them time.

Hence
* happyaxis.jsp: axis' diagnostics page, prints out useful stuff and warns if it knows it is unwell (and returns 500 error code so your monitoring tools can recognise this) * ant -diagnostics: detailed look at your ant system including xml parser experiments.

Good open source tools have to be easy for people to get started with, and that means helpful error messages. If we left the code alone, knowing that the cause of a ClassNotFoundException was the fault of the user sticking the wrong XML parser on the classpath -and yet refusing to add the four lines of code needed to handle this- then we are letting down the users

 This only occurs in linux , in windows its  fine.
do a java -version for me, and an ant -diagnostics, stick both on the bugrep

It may be that XInclude only went live in java1.6u5; I'm running a
JRockit JVM which predates that and I'm seeing it (linux again);

I will also try sticking xerces on the classpath to see what happens next
