:Hello all,
In our web application we use an old version of xerces. We deploy the
application with xerces.jar in the
WEB-INF/lib directory.
However, when the application is started we get the error:
java.lang.ClassNotFoundException: org.apache.xerces.parsers.SAXParser
at
org.xml.sax.helpers.XMLReaderFactory.createXMLReader(XMLReaderFactory.java:118)

com.fredhopper.frob.question.QuestionManager.loadQuestions(QuestionManager.java:163)

com.fredhopper.jsp.Bridge$EngineInServletContainer.run(Bridge.java:779)
A bit cryptic, because SAXParser is in fact available twice (once in our
application and once in the
'global' orion space).
A solution is:
1) Move the following jars:
crimson.jar
jaxp.jar
parser.jar
xalan.jar
2) Move our own xerces.jar in orion home directory
2) Start orion as follows:
java -Xbootclasspath/a:xerces.jar -jar orion.jar
This is not a real solution, because we also had to remove the encoding
attribute out of the application.xml and web.xml. And this should then
be done for every application you deploy on the application server.
Shouldn't it be that when the application server looks for a class, it
first looks in the classes directory of that web application, then in
the lib directory of the web application and if it still can't resolve
the class it looks in the global space (not a good idea, since this
depends on which application server you use, but trade of to save memory
usage)?
So is this a bug in orion, or are we doing something wrong here?
