Tomcat 4.0.3 & getResourceAsStream
Hi!
I´ve just moved an old app that we had running using Jserv to tomcat4.0.3
But i have problems with this
p = new Properties();
InputStream is = p.getClass().getResourceAsStream("/icard.properties");
I keep getting null no matter where i put the icard.properties file.
i´ve placed icard.properties inside WEB-INF/lib and WEB-INF/classes and it´s
also on the classpath...
any workarounds to this issue?... I´m trying not to use the java.io.*
approach...

Re[2]: Tomcat 4.0.3 & getResourceAsStream
Posted by Jacob Kjome <ho...@visi.com>.
Hello Esteban,
It won't work with p.getClass... unless the resource you are trying to
load is in the classpath...meaning it must be within WEB-INF/classes
or WEB-INF/lib/somejar.jar and you wouldn't reference "WEB-INF". The
classloader knows absolutely nothing about it.
If your resoruce was in the root of WEB-INF/classes (root of the
current classloader... also equivalent to putting the resource in a jar file, but
not inside a package in that jar file), the following will work:
p.getClass.getResourceAsStream("/myResource.properties");
This will work if your resource is located relative to the current
class "p" (same package as the class).
p.getClass.getResourceAsStream("myResource.properties");
This will work to find the resource anywhere in the current
classloader (make sure not to prefix with "/"):
p.getClass.getClassLoader.getResourceAsStream("myResource.properties");
This will work to find the resource even if it isn't in the same
classloader. For instance, maybe it is in a parent classloader or a
child classloader relative to the current classloader (make sure not
to prefix with "/"):
Thread.currentThread().getContextClassLoader().getResourceAsStream("myResource.properties");
This will work to find the the resource using the servlet context and
fulfill your requirement to put all properties in WEB-INF/conf:
theServletConfig.getServletContext().getResourceAsStream("/WEB-INF/conf/myResource.properties");
For your purposes, you need the last one. None of the others will
work unless your resource is in the classloader which WEB-INF/conf
isn't.

Re: migration from jrun to tomcat

Just curious. Is your migration extending your app while preseving JRun or
planning to drop JRun when the migration is completed. Thanks.

Hi Esteban
I think if WEB-INF/classes works, any other directory there will
work too.

Thanks for your help andreas.
It didn´t work with p.getClass..
i´m trying with getServletContext().
But my idea is to have WEB-INF/conf to place all .properties files.
is that possible?...

Esteban

Hi Esteban,
try
p.getClass().getResourceAsStream("/WEB-INF/icard.properties");
(inside WEB-INF)
or
p.getClass().getResourceAsStream("/WEB-
INF/classes/icard.properties");
(inside classes)
or
p.getClass().getResourceAsStream("/WEB-
INF/lib/icard.properties");
(inside lib)
If this doesn't work, try
getServletContext().getResourceAsStream(...)
This one will work.
Good luck.

Hi Esteban,
try
p.getClass().getResourceAsStream("/WEB-INF/icard.properties");
(inside WEB-INF)
or
p.getClass().getResourceAsStream("/WEB-
INF/classes/icard.properties");
(inside classes)
or
p.getClass().getResourceAsStream("/WEB-
INF/lib/icard.properties");
(inside lib)
If this doesn't work, try
getServletContext().getResourceAsStream(...)
This one will work.
Good luck.
