getting the getVelocityEngine() method from within a Struts Action
Hi-
I'm trying to send mail from a Struts Action with velocity 1.5 and
velocity-tools-1.2.
The faq:
http://wiki.apache.org/jakarta-velocity/VelocityFAQ
Says:
>>You can get this instance for other uses of velocity by calling
getVelocityEngine
>>from a subclass
Another recommendation from this list was to:
>>To get the VelocityEngine from getVelocityEngine(),
So my question is how do you get the VelocityEngine from the
getVelocityEngine()?
I've spent hours on google trying to find some code that calls the
getVelocityEngine()
but the only thing I could come up with was a VelocityManager class from
opensymphony.
And the VelocityManager.java class from opensymphony is quite complex
and has
many dependencies.
Cheers,

Re: getting the getVelocityEngine() method from within a Struts Action
Posted by Bill Rishel <il...@gmail.com>.
I have extended VelocityViewServlet
and in that class I have:
VelocityEngine ve = getVelocityEngine();
Writer writer = getResponseWriter(response);
// stringWriter has my preprocessed template
ve.evaluate(ctx,(Writer) writer, "footer", stringWriter.toString());
writer.flush();
Which works.

Re: getting the getVelocityEngine() method from within a Struts Action
Posted by David Sperling <ve...@hakodateit.com>.
Thank you both for the examples. I reworked my code to
use a subclass of VelocityViewServlet as suggested. It's
messy code, but it works with MessageTool from within a
Struts Action.
Cheers,
David

Re: getting the getVelocityEngine() method from within a Struts Action

This all looks pretty good! Thanks for sharing it with the list.
i do have few tips inline that might simplify things a wee bit...

if you are also using the VelocityViewServlet and don't mind using the
same VelocityEngine, then you could do what i suggested in response to
your previous email in this thread.

perfect. :)

actually, the ChainedContext is already a VelocityContext, so you can
feel free to directly put your title and text right into it and not
create an additional VelocityContext.

Re: getting the getVelocityEngine() method from within a Struts Action
Posted by David Sperling <ve...@hakodateit.com>.
I got some hints from the Spring project source code, MessageTool
source code and this 3 year old message by Mr. Bubna
"Re: Using Velocity tools in an application?" and finally got
this working.
I wanted to figure out how to access the MessageTool
from within a Velocity context and send the contents via mail.
Hopefully this will help out others having similar trouble.
So to test this out I added entries to my config files:
********************************************************************
This was in my main Strut-Config.xml file:
<message-resources parameter="resources.application"/>
********************************************************************
********************************************************************
This was in a test-config.xml file
<message-resources key="nonStandardResources"
parameter="resources.nonStandardResources.application"/>
********************************************************************
********************************************************************
next the template file: at mywebapp/mailTemplates/testTemplate.vm
$title : $text.get("test.mail.name", ["jon","doe"])
$title with no args: $text.get("test.mail.name")
$title with args and bundle: $text.get("test.mail.name",
"nagisateiHotelResources", ["jon",
"doe"] )
********************************************************************
********************************************************************
Struts Action mapping in the Struts module:
<action path="/test/testSendingVelocityMail"
type = "mydomain.myapp.action.TestSendingMailAction"
scope="request" >
<forward name ="success" path="/test/sendMail.vm" />

i'm not surprised you didn't find much on Google. most
VelocityViewServlet subclasses are probably in proprietart
subclasses. still, it would be pretty easy to make the VelocityEngine
accessible to your Struts Actions. since your actions have access to
the servlet context, you can do a simple subclass of the
VelocityViewServlet that puts the already configured VelocityEngine
into the ServletContext attributes. something like:
public MyVVS extends VelocityViewServlet {
public void init(ServletConfig config) throws ServletException {
super.init(config);
VelocityEngine engine = getVelocityEngine();
config.getServletContext().setAttribute("velocityEngine", engine);
}
}
then you just pull the engine out of the servlet context in your
Struts Action. :)

Re: PANIC : Velocity cannot find any of the specified or default logging ...
Posted by Will Glass-Husain <wg...@forio.com>.
Hi Pascual,
I've never seen that error message in connection with Velocity. Did you say
you were writing a plugin? It's probably an Eclipse classpath problem. Or
are you running under some type of restrictive security policy?
You might consider using the VelocityEngine instead of Velocity.
Velocity.init() sets up a singleton - all other uses of Velocity in the same
classloader will share all the properties. If you create a VelocityEngine
you can have different instances with different properties.

Hi Will,
I mean the instruction
Velocity.init();
the velocitygen is only a constructor that binds values to the velocity
properties.

What's a VelocityGen? That's not in the Velocity distribution. Do the
error messages list what class was causing the problem?

Hi,
I need a little of help.
My plugin in Eclipse that use Velocity was working fine, but suddenly I've
got this velocity message.
systems in the classpath, or the classpath doesn't contain the necessary
classes to support them. Please consult the documentation regarding logging.
Exception : java.lang.NoClassDefFound
It happens just when I execute this instruction.
VGenerator = new VelocityGen();
Any ideas will be helpfull.
Many thanks.

Sounds like you are using the vanilla velocity.jar without the
necessary dependencies. You either need to use the velocity-dep.jar
included in your distribution, or else make sure that either logkit or
log4j are in the classpath.

Many thanks.
Although I can't understand why before it was working , It was that, I needed the library velocity-dep.jar.

Sounds like you are using the vanilla velocity.jar without the
necessary dependencies. You either need to use the velocity-dep.jar
included in your distribution, or else make sure that either logkit or
log4j are in the classpath.

Hi,
I need a little of help.
My plugin in Eclipse that use Velocity was working fine, but suddenly I've got this velocity message.
systems in the classpath, or the classpath doesn't contain the necessary classes to support them. Please consult the documentation regarding logging. Exception : java.lang.NoClassDefFound
It happens just when I execute this instruction.
VGenerator = new VelocityGen();
Any ideas will be helpfull.
Many thanks.
