Servlet Caching Bug?

[Ted Rice]

We've experienced what we believe to be
a bug with Orion in terms of Servlet Caching.
The situation is detailed here:

1. We've setup a servlet as a filter for xml, by
   editing orion's global-web-application.xml thusly:

servlet-chaining servlet-name="XSLPainterServlet" mime-type="text/xml"/
servlet
servlet-nameXSLPainterServlet/servlet-name
servlet-classcom.apama.xsl.XSLPainterServlet/servlet-class
/servlet



2. Additionaly, we've edited orion's application.xml thusly:
library path="../../dev/ApplyXSLServlet"/

   and a jar file is placed in this directory containing the
XSLPainterServlet
   file.


We've tested this with an XML file and it works fine.

The problem is when we recompile the class file and rebuild the JAR file
while
Orion is running, the new servlet is not used. Orion continues to use the
old
servlet in memory.

Is there anyway to hot-redeploy servlets without explicitly restarting
orion?

Thanks,

Ted Rice

Yes, put your servlet in the /WEB-INF/classes directory of your web
application.

library is for classes loaded at startup and for use in every application,
these will not get reloaded. (Eg in months and months of using Orion, I've
never once needed a library tag)

The only purpose I've put it to is the jdbc classes for oracle and our organisations
class tree so that these don't need to be in the orion structure.
