VelocityServlet and Properties file
Ok, I know VelocityServlet is depricated in favour of the VelocityViewServlet
but i started my web-app before VelocityServlet became deprecated so to keep
consistency (for now) i'm using it.
Anyway my problem is that my servlet can't seem to find my template. I've
tried putting it in / , /obb, /obb/WEB-INF but it doesn't seem like it wants
to pick it up at all. Also i'm not sure that its picking up the
velocity.properties.fileloader file.
I got around this problem in the other servlets by overwriting the
loadConfig() and making a new instance of Property. This was fine until i
actually wanted to specify some of my own and it would be handy to have them
all in one place.
thanks in advance
public class EditPage extends VelocityServlet{
public Template handleRequest(HttpServletRequest request,
HttpServletResponse response,Context context) {
// stuff in here
//Merge the Template now
try{
String templateName="edit.vm";
template = getTemplate(templateName);
}
catch(ResourceNotFoundException rnfe){
System.out.println(templateName);
rnfe.printStackTrace();
}
catch(Exception e){
e.printStackTrace();
}
return template;
}
}
and my directory structure works like this (slightly different to normal as it
allows me to use mod_jk to map www.domain.com to / )
-/myapp/
/obb/
WEB-INF/
classes/
lib/
- velocity.properties.fileloader
- web.xml
- obb.war
- edit.vm
- index.vm
velocity.properties.fileloader
----------------
resource.loader = file
file.resource.loader.description = Velocity File Resource Loader
file.resource.loader.class =
org.apache.velocity.runtime.resource.loader.FileResourceLoader
file.resource.loader.path = .
file.resource.loader.cache = false
file.resource.loader.modificationCheckInterval = 0

Thanks Wil,
Where abouts is the WebappLoader located? I can't seem to see WebappLoader in
the Velocity 1.4 API, the JDK Api or Tomcats Api.

You need to import the RuntimeConstants and WebappLoader classes.

Re: VelocityServlet and Properties file
Posted by Andrew Mason <an...@assertis.co.uk>.
Sorry if i seem a bit dense but i'm still having alot of trouble getting this
to work.
in my loadConfiguration() i tried
{
Properties p = super.loadConfiguration(config);
Velocity.setApplicationAttribute("javax.servlet.ServletContext",config.getServletContext());
p.setProperty(RuntimeConstants.RESOURCE_LOADER, "webapp");
p.setProperty("webapp.resource.loader.class",WebappLoader.class.getName());
}
but then i would get the following errors
[javac] Compiling 1 source file
to /home/am/OnlineBizBuilder/obb/WEB-INF/classes
[javac] /home/am/OnlineBizBuilder/source/com/assertis/obb/LinkManager.java:52:

[javac] location: class com.assertis.obb.LinkManager
[javac]
p.setProperty("webapp.resource.loader.class",WebappLoader.class.getName());
[javac] ^
[javac] 2 errors
This is my properties file which is located
in /obb/WEB-INF/velocity.properties
resource.loader = class
class.resource.loader.class =
org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
runtime.log = velocity2.log
file.resource.loader.cache = false
file.resource.manager.logwhenfound = false
i would like to be able to set all of the velocity options from this file ,
and IF possible, allow my webapp to use it for its properties too, since i am
loading it up for velocity anyway (which all of my servlets use).
Many thanks

no, no, no. this should be handled only once during servlet init via
the overridden loadConfiguration method that Jason suggested. and
though i didn't include it in my example, the first part of his

both VelocityServlet and VelocityViewServlet will first search the
servlet config's init-params, then search the servlet context's
init-params. so the answers to your questions are no and yes,
respectively.

Thanks Nathan,
This is what i was trying to get it to (after checking out the source),
but i couldn't work out how to do it. I will try this as soon as I get
to work. I'm trying to make this as fool proof as possible for any
developers that may come after me.

this is what the WebappLoader used by the VelocityViewServlet does
automatically. you can use it without using the VelocityViewServlet,
just specify it in your properties and put the servlet context into
Velocity's application attributes. it would be something along these
lines for your example above:
Velocity.setApplicationAttribute("javax.servlet.ServletContext",
config.getServletContext());
// by default, load resources with webapp resource loader
p.setProperty(RuntimeConstants.RESOURCE_LOADER, "webapp");
p.setProperty("webapp.resource.loader.class",
WebappLoader.class.getName());
this will make the webapp root the default search path, but you can
specify others (relative to the webapp root) using as many
"webapp.resource.loader.path" properties as you like.

Re: VelocityServlet and Properties file
Posted by Jason Pettiss <ja...@TheCatalis.com>.
I have the same situation... this is what I do in my loadConfiguration
method:
//Configuration file to be read is specified as
//the init param 'org.apache.velocity.properties'
Properties p = super.loadConfiguration(config);
//For ease of use, our templates are found in our webapp,
//just as if they were JSPs
String path = makeServletContextPath(config.getServletContext());
//Tell Velocity where we expect our templates to be
log.debug(Velocity.FILE_RESOURCE_LOADER_PATH+"="+path);
p.setProperty(Velocity.FILE_RESOURCE_LOADER_PATH, path);
return p;
Then I just put my templates in the same place as my JSP pages and if a
request comes in for /dir/foo.vtl I just serve that right up.
The only other thing you'll need is that you tell the servlet in your
web.xml where to find the default properties bundle:
<servlet>
<servlet-name>getter</servlet-name>
<servlet-class>org.foo.bar.MyCustomVelocityServlet</servlet-class>
<init-param>
<param-name>org.apache.velocity.properties</param-name>
<param-value>/WEB-INF/velocity.properties</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
And the only thing I need in my velocity.properties is:
runtime.log.logsystem.class=org.foo.bar.VelocityLogger
Since I have a custom logger. The rest of the file loader stuff except
for the modfication interval you should just remove since I think those
are the defaults anyway, except for the path, which we're setting with
our loadConfiguration method.
You might look at the implementation for the super loadConfiguration
method-- but it may require that velocity.properties actually end with a
".properties" extension. I doubt it, but if you do all this and it
still seems your file is being ignored, try that.
