Re: Initializing Velocity ouside of a servlet
Hello Leo,
For starters, try and initialize velocity with a Properties object loaded
using a Resource. Make sure that velocity.properties is in the classpath.
e.g.
InputStream vProps =
this.getClass().getResourceAsStream(/velocity.properties);
try {
Properties properties = new Properties();
properties.load(vProps);
VelocityEngine velocityEngine = new VelocityEngine();
velocityEngine.init(properties);
VelocityContext context = new VelocityContext();
}
catch(Exception e) {
logger.error(velocity engine failed to initialise, e);
}
Also, in velocity.properties you have to specify the template loader to use.
(have a look here for template loaders,
http://jakarta.apache.org/velocity/developer-guide.html#Configuring%20Resource%20Loaders)
Try ClasspathLoader
--
resource.loader = production
production.loader.description = Production Resource Loader
production.resource.loader.class =
org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
--
When using velocityEngine.getTemplate(String) just make sure that the path is
in the following format
templates/myTemplate.vm
and that templates/ dir is in the classpath since you are using a
ClasspathResourceLoader

Markos

Hi!
What is the right way to initialize Velocity outside
of a servlet? My application works fine when I'm using
VelocityViewServlet, but when I'm trying to initialize
Velocity from any standard Java class (with
Velocity.init(absolutePathToPropertiesFile))
Velocity.mergeTemplate always throws
ResourceNotFound exception.
I guess this happens because Velocity cannot get
parent directory of a web application without a
reference to servlet context. But I'm not sure what I
can do with this. I can't specify absolute path in
velocity.properties and I would prefer to avoid
setting path properties directly in the code (I don't
know how to it anyway - tried
Velocity.setProperty(file.resource.loader.path,absolutePathToTemplateDire
ctory) and it didn't work).
Maybe it's possible to pass a default directory path
somehow?

Yeah its true that I use request.setAttribute(destinations, destinations) at

this seems to indicate that there is something in either your request

message-resources parameter=DestinationsResources key=destinations /

$text.get('title.img', 'destinations')

changed the key of the message resource to destination (notice the 's'
missing)
using the new key value... and it works :/
thats using velocity-tools-1.1
I also have other resources that use the same notation,
message-resources parameter=IndexResources key=index /
and cause me no problems.

Struts Velocity
Hi all, Im just trying to get my head around this. Struts is meant to work with actions. You create the mappings of the actions in the struts-config.xml and define things like action handlers, forwards, etc. Suppose I use Velocity to render the view. Is there a standar place in struts or anywhere else that I can populate the velocity context? (Doing it through request.put() of course) My problem comes when I need to change the Locale for a page which fires up a LocaleAction class which then renders the page Ive specified *but* without the velocity context being populated since all the logic to populate the context is defined in a different class. In Turbine for example there is method which gets called and serves for populating the context. Thanks for your input.

Re: Struts Velocity
Thanks for your input! The easy way is to use the Velocity Servlet in velocity tools. By mapping say any vm file to the servlet you can process vm files. And yes, putting the data in the request or the session will make it available to the view. There isn't anywhere else really. Yeah thats what im doing :D The exception is where method calls are made directly from the Velocity I suppose. Perhaps I'm dumb - but why is an action - the LocaleAction rendering anything? Shouldn't that be the job of Velocity? I didnt put it correct. I dont mean that the LocaleAction renders the page, I mean first calling LocaleAction *and* then rendering the page. So the question is when to call request.put(). At the moment I found a solution by declaring a global forward which always calls the associated action with a given page (passed as a parameter) which handles the request.put in the execute method. However, Im not 100% sure its the right way since I would imagine an Action class would only handle all the business logic to prepare the objects for request.put and not actually making it. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Struts Velocity
Peter, you are 100% right that it should belong there.
