RE: Adding jars in shared hosting environment

["Fernandez, Obed" <ObedF@mediaocean.com>]

My two cents...

Just unpacking the jar won't work. Even if you managed to get the class
files into a classpath directory, they probably wouldn't be picked up by the
servlet engine until it is restarted. Placing your own classes into ext
directories is almost always a bad idea for various reasons I won't get into
here.

My suggestion, if they allow you to upload WAR files: Put the jar files that
your app depends on in the /lib directory under WEB-INF. I believe most
servlet engines will add those jars dynamically to your web app's classpath.

Let me know if it helps.

Subject: Adding jars in shared hosting environment


I am able to run servlets on the server space that I rent from a hosting
company. They give me a servlet directory that I can put my servlets in.
They don't have any JAXP parsers or anything installed and available, and
they're not about to install anything special for 1 person.

How can I use components like crimson.jar if I cannot add them to the
CLASSPATH or put them in jre/lib/ext?

I tried putting crimson.jar in the servlets directory, that didn't work.

I tried unpacking crimson.jar and putting the class files in the appropriate
subdirectory in the servlets directory. e.g. I put SAXParserFactory.class in
servlets/javax/xml/parsers/. That didn't work.

To test to see if the classes are being picked up I just tried to create a
SAXParserFactory object. e.g.

I get the "The server encountered an internal error or misconfiguration..."
error.

Has anyone done this? It seems like I should be able to uses these classes
even if I cannot change the CLASSPATH or put them in jre/lib/ext.
