[ANNOUNCE] VelocityTools 2.0-beta2 Release

2008-07-15T08:23:52Z

The Velocity developers are pleased to make the second beta release of
VelocityTools 2.0 available for download.
Downloads are available here:
http://velocity.apache.org/download.cgi

Major development in VelocityTools 2.0 has been essentially complete
for some time, and the focus is on fixing the remaining bugs,
completing the documentation, and providing clear migration paths for
users of VelocityTools 1.x. Significant new features in 2.0 include
very flexible, composable toolbox configuration (via either java, xml,
and/or properties), lazy-loading/initialization of tools, the
VelocityViewTag for embedding Velocity within JSP, simplified
embedding of VelocityTools in other frameworks, an assortment of new
and improved tools, and much more.

This should be useable as a drop in replacement for Tools 1.4, with a
few minor exceptions where things already deprecated earlier in 1.x
have been removed. The 2.x series of VelocityTools also requires both
Velocity 1.5+ and JDK 1.5+.

At this point, the new tool management and configuration facilities
are extremely stable and useable. Documentation has continued to
improve dramatically and is nearing completion. There are no open or
known bugs in this release nor significant changes anticipated before
2.0 final is released.

We are very interested in all feedback regarding Tools 2.0, especially
regarding backwards compatibility with apps designed for Tools 1.4 or
earlier. We aim to enable a smooth, incremental transition for
developers and their applications.

Re: How do I make velocity preserve new lines in the output

2008-07-12T13:02:31Z

That's odd. If i remember correctly, the only newlines gobbled should
be when a #set directive is on a line by itself or when any other
directive (#foreach, #end, etc) is both on a line by itself and has no
preceding whitespace. So the example template you gave should have
plenty of new lines.

What version of Velocity are you using? And are you doing any other
processing of the content?

Re: how to define global variable in velocity template ?

2008-07-12T12:54:20Z

all variables set within a template are "global" to that template.
how are you using Velocity? global can mean very different things
depending on the application involved.

How do I make velocity preserve new lines in the output

2008-07-11T14:28:44Z

Hi,

I am using velocity to output a groovy script.

My velocity template is something like this.

#foreach $c in $a

def ${c}function()

{

....

}

#end

The output that gets generated puts everything into one line and groovy
fails to evaluate it since it expects each function definition to start
with a new line.

Essentially this is how the output gets generated at present.

def afunction() { ... } def bfunction {...}

Is there any way I can have velocity preserve my formatting when the
output is generated ?

Thanks,

Roshan

Re: Does Velocity have a shutdown mechanism?

Yeah, it's always been parsers, never threads. :) Glad Velocity is
off the suspect list. You might try asking the Tomcat list for ideas
on how to track this down. Good luck!

Re: Does Velocity have a shutdown mechanism?

2008-07-11T09:32:01Z

My misunderstanding; I switched logging back on to get the exact message
and I see that it just says that it creates '20 parsers'. I could have
sworn that these were threads (perhaps in an earlier version? I've been
using Velocity since version 1.2) but this is obviously not true.

I'll have to try to isolate the cause of this problem, but at least I can
now eliminate Velocity from the list of suspects. I should have figured
this wasn't the problem, since I use VelocityViewServlet for just about
every webapp I create (no JSPs in *my* house :) and I've never seen this
issue on any of those apps.

No, there's no "shutdown" method. But then, there really isn't much
to shutdown. Velocity doesn't spawn its own threads. There's not
really such a thing as an "engine thread" to my knowledge. You could
have an application that init'ed 20 engines, but i don't know why
you'd want to do that. You could have a servlet that is processing 20
requests using one or more VelocityEngines (i'd recommend one for most
cases), but again, those would be request threads and not in
Velocity's control. What is it you see in your log file that reports
these "engine threads"? I'm no Tomcat expert, but perhaps i can clear
up some confusion...

Does Velocity have a shutdown mechanism?

2008-07-10T09:09:30Z

I'm seeing a strange problem in Tomcat 6 when I undeploy an application
containing a servlet that starts a VelocityEngine. In the servlet's init()
code I create, configure and init() the VelocityEngine; the log file
reports that 20 engine threads have been created.

When I undeploy, the app doesn't disappear cleanly (after the undeploy,
clicking the List Applications button on the Tomcat Manager screen shows
that the app is still there, and the app is still in the webapps/
directory). I'm not sure but I think that the app isn't completely closing
because the Velocity threads are still running. (I'm working on comfirming
that this is the cause but at this time I can't be certain.)

Does the engine have a shutdown method that I can call from the servlet's
destroy() method? I don't see anything in the API documentation. Is there a
recommended way of telling a VelocityEngine to stop?

are you using VelocityTools? if so, add the ContextTool in request
scope. it will get you all possible context values:

if you put the context in the context, then it will not be null. :)

Getting all variables define in context

2008-07-09T09:59:02Z

How do I get all keys that were set by java app.?
i.e.

Java:
context.put("name", "Velocity");
context.put("project", "Jakarta");

Velocity:
$name
$project
$versionDoesNotExist

#foreach($key in $application.attributeNames) works good, but not what I need!

#foreach($key in $context.keys) does nothing; because $context is null?
so
#foreach(??? in ???)
return
"name","project"...etc

design template and store it in database

2008-07-07T08:40:49Z

Hi
Is there any tool that can be embedded in a web application so that a particular user can design and store that template in database based on their requirement, here the templates that contains the components mainly consists of input type and once the user designed template she/he has the option to store that in database, so that later point of time he/she can use the stored template. whether this type of design supports in velocity ie, apart from the view similar to what scarab project does (which displays based on template from file , but i need just the opposite. ie, design and store the template in database from running web application). whether velocity support that kind of thing or similar to that.

Thanks
Kumar

RE: quiet reference doesn't throw exception

Actually, in that case the $isNull inside the if statement throws the

How about

#if($isNull)
(nothing)
#else
$!isNull
#end

This is quite verbose, but it will get the job done.

I've always been a proponent of something like ReferenceTools that would
allow you to do things like directly check for null and false (because
null == false in VTL) so you wouldn't have to use tricks like these to
get around this behavior. I've just been too lazy to do anything about
it so far ;)

Hi,

I'd like to thank you too for the quick reply and support. Allowing to
provide custom velocityviews would be great. I've already tried to do
that with version 2.0alpha1 but had not found a way to configure
velocity to use it.

i'm not sure if it's just a typo in your email or if it's a problem in
your actual template, but you said you are trying to do:

#parse( 'commom.vm' )

and have it find a "common.vm" template. is it as simple as changing it
to

#parse( 'common.vm' )

?

File Resource Loader "Unable to find resource " error for #parse files

2008-07-03T19:14:00Z

Hi,

I have a batch application that is using velocity create the content for
emails.

I keep getting an "" when trying to merge a template that contains a
"#parse" statement. I don't have this problem on a Web Application that
uses an identical Spring Context Config to create a velocity bean.

Questions:
1. How do I figure where velocity is looking for the file reference by
the #parse statement? If I knew where velocity expects to find it I can
fix the problem.
2. The Velocity User Guide says that files referenced by #parse must be
under the TEMPLATE_ROOT directory. How do I sent the TEMPLATE_ROOT
directory? How do I determine the location of the TEMPLATE_ROOT
directory when my application is up and running?
Thanks
Todd McClintock

Re: Tools 2.0 / VelocityLayoutServlet / loadConfiguration

2008-07-03T16:10:34Z

Hi Martin,

You're right. There is no good replacement for this yet. Thanks for
catching that! I have some unchecked-in code for allowing people to
easily tell VelocityViewServlet (and kin) to use a custom subclass of
VelocityView. I think i'll run some tests and check that in. Once
that feature is available, you will want to create a class like this:

package org.com;

import org.apache.velocity.tools.view.VelocityView;
import org.apache.velocity.tools.view.JeeConfig;
import org.apache.velocity.app.VelocityEngine;

public class MyVelocityView extends VelocityView {

public MyVelocityView(JeeConfig config) {
super(config);
}

protected void configure(JeeConfig config, VelocityEngine engine) {
super.configure(config, engine);
// i leave it to you to determine where the customUrl value comes from :)
engine.setProperty("url.resource.loader.root", this.customUrl);
}
}

and add this to your VelocityLayoutServlet's web.xml config:

<init-param>
<param-name>org.apache.velocity.tools.view.class</param-name>
<param-value>org.com.MyVelocityView</param-value>
</init-param>

And i think that should do the trick. Of course, first i have to
clean up and check in the code that lets you subclass VelocityView
like this.

And really, thank you for catching this before 2.0 final is released!
This is exactly the kind of feedback we need to make sure people can
migrate from 1.x.

quiet reference doesn't throw exception

2008-07-03T15:20:19Z

I'm using the velocity engine with ParseErrorException throwing turned
on because it greatly simplifies unit testing, as it just checks that
every value on the page has been filled in. However, I'd like velocity
to not throw an exception when I pass it a quiet reference e.g. $isNull
should throw an exception, but $!isNull should just resolve to being
empty. Is there a way to do this?

Thanks,
Seth Rosenblum

Re: design template based on user requirement

2008-07-03T13:14:11Z

Hi Kumar,

Velocity doesn't come with any Hibernate-specific resource loaders, but
there is a DatasourceResourceLoader that can load a template directly from a
database. Check the Javadocs.

Also, it is possible to write your own ResourceLoader to load templates.
You could definitely create one to load from a Hibernate session. Look at
the source code for the DatasourceResourceLoader in the Velocity source as
an example, or read my Powerpoint slides "Hacking Velocity" available on our
wiki.

Tools 2.0 / VelocityLayoutServlet / loadConfiguration

2008-07-03T09:49:48Z

Hi,

I'd link to migrate from Velocity tools version 1.3 to version 2.0. With
version 1.3 it was possible to change the root-URL of the
URLResourceLoader by simply overwriting the method
"loadConfiguration(ServletConfig config).", e.g.
> @Override
> protected ExtendedProperties loadConfiguration(ServletConfig
> config) throws IOException {
> ExtendedProperties props = super.loadConfiguration(config);
> props.addProperty("url.resource.loader.root",this.customURL);
> return props;
> }
With version 2.0 this seems not to be possible anymore. What is the best
way to do the same with the new tools version?

Thanks.

Re: design template based on user requirement

2008-07-03T06:24:42Z

yes but the thing is that user has to design a new template and store in database, but this design and all things should happen in running mode of web application, ie it should be possible to design all the web components like text box, combo box, check box in running web application and once the new template is created that template should store inside the database up on clicking suppose save button,

and for programming i am using JSP,Hibernate for database connection, how it is possible. do u know any tools available so that one can dynamically create template and store inside database.

thanks

RE: design template based on user requirement

2008-07-02T06:41:36Z

If I understand your question correctly, you have your own template, and
you want to let the user override it with their own customized version.

One way to do this is with resource loaders.

For example, if your templates are inside the .war file, you could set
the resource loader configuration to check a file system location first,
and then inside the .war.

If it finds a version of the template it's looking for (same exact name)
in the file system location, it will use that. Otherwise, it will use
the version from the .war.

Hope this helps,

Tim

That was it! That cleared up about 60 validation warnings from W3C validation tests. Thank you. You can see the result already on http://www.jobbank.com. With that change, there is no need to change DOCTYPE? By the way, I could not find this on the velocity site. Maybe I missed it. It was a good tip to know.

If they're regarding the actual Velocity classes (versus some of your
