[jetty-discuss] Running Jetty offline - schema_reference errors.

[Leif M. <lei...@ta...>]

I have always used Jetty embedded within other applications. Recently,
I have been attempting to upgrade to the latest CVS code and have been
running into problems when attempting to run on an off line computer.

The WebApplicationContext class now defines a defaultsDescriptor,
org/mortbay/jetty/servlet/webdefault.xml which contains references
to online files:

<web-app
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">

When I run my application on line, the application starts up very slowly but
it will start. When I run off line however, I get a large number of errors
caused by the inability to locate
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd
I assume that is what is slowing down the startup while connected as well.

WARNING@jar:file:/<path>/lib/jetty-20031015.jar!/org/mortbay/jetty/servlet/webdefault.xml
line:26 col:18 : org.xml.sax.SAXParseException: schema_reference.4:
Failed to read schema document
'http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd', because 1) could not
find the document; 2) the document could not be read; 3) the root
element of the document is not <xsd:schema>.

I have been able to work around this by overriding the webdefault.xml
with a file that does not specify the schema location etc. But that is
not ideal.

I notice that when I run Jetty using the normal startup method, by just
running "java -jar start.jar", Jetty not only start up quickly but has no
problems with being off line.

I have spent quite a bit of time trying to figure out what the start/Main
class is doing to disable the validation(?) that is leading to my problems
but have thus far not been able to figure it out. Any advice would be
greatly appreciated.

I noticed the org.mortbay.xml.XmlParser.NotValidating property, but
setting that to true does not seem to have any effect.

Thank you in advance,
Leif
