Re: set directive and CSS syntax
The Velocity syntax looks ok to me. The quotes don't matter, they are
outside of the reference.

So we have set a bunch of variables to use as inline CSS directives

Note that the url is single quoted. I noted this was a problem and
removed them, leaving:

#13aaf3; background: white url(${IMAGE_SERVER}/path/to/image) top

This did not seem to correct the problem we are having and I'm
attributing it to the
url(${IMAGE_SERVER}/path/to/image) portion itself.
Is Velocity misinterpreting the url() call as a VM, or something else?

Re: bizarre ClassNotFoundException when running in Eclipse
You can get odd behavior with 1.4 when running Velocity from a jar outside of the application classpath. For example, having the velocity jar in a container while the calling app is in a webapp. We've fixed this with upcoming release 1.5 (download the beta http://people.apache.org/dist/jakarta/velocity/v1.5beta1/ ). Now it searches for all plugins, templates etc in the ThreadContext classpath first. The result is much more intuitive behavior in these type of circumstances.

Re: Which variables are involved in a template?
The latest version of Velocity (1.5) has an event handler
InvalidReferenceEventHandler that allows you to capture bad
references. It's not yet documented but you can read the docs on
event handlers, then look at the javadocs for this specific one.
It's available in svn, we'll do a beta release soon.

Hello Javier,
just an idea.
Perhaps you can use the velocity log mechanism to get the information.
In version 1.4 (in v1.5 the API is a bit different I think) you can
write your own logging class for velocity. So there you can parse the log
messages.
It's more a dirty solution, I think. Hopefully the developers have a better
idea. :-)

Betreff: Which variables are involved in a template?
Hi,
I am developing a tool using velocity. In my application the user write
down a template and then it is evaluated within a velocity context. But
somtimes not all variables in template are found in the context. So I
need a mechanism to recognize which variables could not be resolved.
One solution is evaluate once the template and then parse it looking for
string maching with $ or ${}. My question is: Is there any other
more straitforward mechanism within the velocity API that give me the
list of unsolved variables? Or at least, is there a method in velocity
API that returns the list of referenced variables witin a template?
Thanks in forward.

Re: Velocity Config/Security Issue
Hi Robin,
I set up a test server and duplicated this issue. Here's the
specifics of what's going on with a suggested solution (long email).
By default, the Tomcat security manager policy prohibits reflection on
classes in the org.catalina hierarchy. This prevents web apps from
instantiating internal classes and doing things it shouldn't be doing.
When you write a JSP page that calls %= request.getSession().getId()
% this is literally compiled into a class. Since the code is called
directly, it works fine.
As a contrast, when Velocity calls $request.session.id it uses
reflection. Since the $request reference is actually implemented by
org.apache.catalina.connector.RequestFacade (in Tomcat 5.5) any method
calls using reflection throw a security exception.
There are two possible solutions.
(1) Your hosting provider should add the following to the security
policy. Note it is very specific - just applies to the two velocity
jars. You'll need to change the path to match your webapp.
grant codeBase
file:${catalina.home}/webapps/simple/WEB-INF/lib/velocity-1.4.jar
{
permission java.lang.RuntimePermission
accessClassInPackage.org.apache.catalina.connector;
permission java.lang.RuntimePermission
accessClassInPackage.org.apache.catalina.session;
permission java.lang.RuntimePermission
accessClassInPackage.org.apache.catalina.core;
};
grant codeBase
file:${catalina.home}/webapps/simple/WEB-INF/lib/velocity-tools-view-1.2.jar
{
permission java.lang.RuntimePermission
accessClassInPackage.org.apache.catalina.connector;
permission java.lang.RuntimePermission
accessClassInPackage.org.apache.catalina.session;
permission java.lang.RuntimePermission
accessClassInPackage.org.apache.catalina.core;
};
(2) You can create your own implementations of HttpServletRequest and
HttpSession that simply delegate to the app server versions. Since
your classes are outside of the org.catalina hierarchy there will be
no reflection-related security issues. Then add your new wrapper to
the context with the same name request.
To sum up, this issue is due to the use of reflection by Velocity and
a strict security policy in Tomcat. Either changing the security
policy or changing the target of the reflection would solve the
problem.
I'm going to post a JIRA issue to the Velocity Tools list suggesting
that the project add a wrapper for $request to eliminate this issue.
Best, WILL
On 10/13/06, Robin Mannering [EMAIL PROTECTED] wrote:
Hi Will,
Originally, any request to the $request object were just being ignored (or
were throwing security exceptions). So the Velocity page just output
$request into the HTML.
He then granted permission on the below package uisng the security manager
and the request object was then 'working' although it was putting out the
incorrect values. The exceptions in the log then disappeared.
Then, he ran the application without the Security manager and the $request
object had expected values for methods such $request.contextPath and
$request.session.id and everything worked fine.
I'm unfamiliar with Security Managers, shall I ask him to apply just this
one? (This has no reference to Velocity classes does it?)
java.lang.RuntimePermission accessClassInPackage.org.apache.catalina.core
As an extra, do you know of a hosting company that has established clients
using Velocity? I might do well to move somewhere with direct experience of
hosting with velocity.
Thanks for all your help

Re: help in calling a class in a velocity template
Noo... #set($newobject = $foo.class.forName(myclass).newInstance()) is just not a good way of doing this. It's error-prone, hard to read, may not be supported in future versions of Velocity. Instead, create an instance of the object and put it into the context before Velocity is called with context.put(newobject, new MyClass()); Note to Claude: I've got a new (simpler) Uberspector subclass that addresses this. I'm going to integrate it into 1.5 during our Hackathon in two weeks. WILL On 9/29/06, Claude Brisson [EMAIL PROTECTED] wrote: Do you mean : How to put a new instance of a class in the velocity context from inside the vtl? Usually, you put classes in the context using java (context.put(name,object)), or using toolbox.xml if you rely on the VelocityTools subproject. Now, if you really want to load a new instance of a class in the context from inside the VTL, you have the following hack: #set($newobject = $foo.class.forName(myclass).newInstance()) where $foo can be any existing reference. But this is really not a very clean coding style... Also, the class you load must have a default constructor (otherwise it is still possible but more complex). By the way, dev people, why is this issue only scheduled for 1.6?

You don't NEED anything from 1. To be honest, I wouldn't bother with any other MVC framework until you learn velocity and all it offers. All you need to do to get velocity based pages to render your computer is: Install Tomcat and then Velocity. That's it.

I think you could just put a tiny example of a servlet code overriding the loadConfiguration() method. I know that it's explained on that section, telling that if you want to set properties at startup you could use it, but for newbies this is to much hidden (they're just learning that Velocity looks in a specific path for the templates). Notice that the text refers to the examples: The following code is SIMILAR to the SampleServlet.java class included in the distribution in the examples directory. It's SIMILAR. It would not work for anyone trying it. Then I thought it would make sense to just google for that (ResourceNotFoundException). None of them could help me. I thought it would be too stupid to post one more on the web. Finnaly, as I tend to look at code samples too late (because I like reading about the subject and seeing examples intermingled with text), I found one example that comes packaged with Velocity.

webapp classpath. You might try Velocity 1.5-beta. (will be released
momentarily).

hi Velocity team:
I am an user of Velocity from China. Thanks for your perfect production.
Through your creative and hard work, we have such Convenience and Powerful

1) in Escaping VTL Directives section.
\\#if( $jazz )
Vyacheslav Ganelin
\\#end
In this case, if $jazz is true, the output is
\ Vyacheslav Ganelin
\
after i run this code fragment,the output is :
\ Vyacheslav Ganelin \
i think it's reasonable,because there is no br tag,so the
browser(my is IE 6.0) doesn't output the backslash in a new line.
2) Advanced Issues: Escaping and !
#set( $foo = bar )
$\!foo
$\!{foo}
$\\!foo
$\\\!foo
This renders as:
$!foo
$!{foo}
$\!foo
$\\!foo
My output is:
$!foo
$!{
$\!foo
$\\!foo
i was confused.
---
Contrast this with regular escaping, where \ precedes $:
\$foo
\$!foo
\$!{foo}
\\$!{foo}
This renders as:
\$foo
\$!foo
\$!{foo}
\bar
My output is:
$foo
$!foo
$!{foo}
\bar
it seems like clerical error.
3) Velocimacro Trivia
Currently, Velocimacros must be defined before they are first used in a
template. This means that your #macro() declarations should come before
using the Velocimacros.
i defined VM after they are first used in a template, it also work. i
don't know why.
hope your reply.

${jMap}.put(ttt123,test)
Uhm, no?!? ${jMap.put(...)} _is_ correct.
If you write ${jMap}.put(), you force Velocity to evaluate ${jMap}
without looking at the surrounding template code. This leads to
executing jMap.toString() which renders the map as text and then
adding .put(...) after it.
The reason Velocity works this way is that templates are typically used
to just display data. They very rarely change internal state. (makes
for less error-prone programming). If you want to call put from
within your template and not have it return null, you'll need to write a
Map wrapper which is either defined void or returns an actual value.
... or use the quiet notation $! or use 1.5-dev where you can set a property to
have null as a valid reference.

Second, the put call works fine in your example. But since it returns

doing a get after the put.

Re: Overriding the default precedence of the template engine
Hi Mike, Not sure. The basic premise behind Velocity is this notion of the application providing the context and then the template being filled out. Such an approach keeps things simple. You might look at the Velocity Tools project -- there's a item called RenderTool that lets a Velocity template evaluate more text within itself. WILL Smith, Mike H wrote: Hi, Is there a way to modify the precedence logic of the template engine? In particular, I'd like to: 1. Define a template like: #set( $this = Velocity) $this is great! 2.

Re: Extracting a list of keys from a string based template
Hi Mike, First, a quick side comment. Velocity.evaluate() does work fine. But if you are calling Velocity repeatedly, consider using a resource loader like FileResourceLoader or ClasspathResourceLoader. The caching mechanism in the resource loader speeds up things tremendously. Velocity is more aimed at generating the text rather than parsing it. It doesn't contain much in the way of identifying content. It's possible you might load the file in a resource loader, take the returned Template object, and break it down into to the constituent parsed nodes. But since this is essentially an internal structure, the specific node types it might change in future versions. WILL Smith, Mike H wrote: Hi, I'm a Velocity newbie, and am evaluating to see if it can address our relatively simple requirements. I need to use String based templates. After a bit if digging around I found the following function: Velocity.evaluate( context, writer, , templateString ); This works pretty well for our purposes. However I also need to get a list of candidate keys from the template String. So if my template contains: $a $b I need to extract [a,b]. Thanks.

Re: Putting key/value pair into hashmap from velocity template
Hi Matthias--
There's no magic. If there are parens, it assumes it is a method call
$abc.foo(data)
calls the foo method with the argument data.
$abc.foo
would call either getFoo(), getfoo() or (for a Map) get(foo)

Thanx Chris,

It's still the same error.
I also tried to use the method set(index, object) from arraylist, but this also

I guess that velocity does some magic and don't calls the put-method from
hashmap or the set-method from arraylist.
I have verified both tests by calling the methods clear() and size() on hashmap
and arraylist to be sure, that the objects exists in the velocity context.
I have found at http://www.freebok.net/help/velocity4.html the following
example:
$sisyphus.pushRock()
## Velocity assumes I mean $sisyphus.getRock()
Its not discussed in detail what the author meant by his example, but I wonder
how velocity assumes method calls.

macro not being called
Hi, Just a quick query. Has anyone else had problems with repeated or simultaneous macro calls not executing? I've a template that does 10 macro calls in quick succession with a #parse'd header file.

I'm suspecting some subtle race condition, but it's hard to replicate this on my dev machine.

Subject: How can I get the length of Array ?
Hi all,
In the Velocity realm, how can I get the length of Array ?
For instance,
#set( $arr = __set int[] value__ )
#if( $arr.length 0 )
...(snip)...
$arr.length is always null. Why ?
I always use helper Object to avoid this issue.
For example,
$helperObj.lengthOf( $arr )
This method, lengthOf, is described below:
public int lengthOf( Object[] objects ) {
if( objects == null)
return 0;
return objects.length;
}
Best Regards,

Re: How can I get the length of Array ?
That'll teach me to read the question fully before answering...
#set($abc = [1,2,3])
actually creates an ArrayList, so any List method-- such as size()--
will work.

Re: Static Template Validation?
Elmar, Nice idea. It's been discussed briefly on the list before, but there's no implementation. There's two sides to it. (1) validation of template and (2) performance improvement through compilation. My personal opinion is that validation would be a major benefit, but that compilation may or may not matter. (Performance with Velocity's built in caching system is pretty good). WILL Elmar Jürgens wrote: Hi, I am using Velocity to generate Java classes for a custom target framework (also written in Java). Every time I change my target framework, I have to adapt my velocity templates accordingly. I am looking for a way to statically validate the Java code contained in my velocity templates, in order to automatically find those spots in my templates that I have to adapt to a change in the underlying framework. My first guess at a static template validator would be to somehow transform a Java-generating-template into something one can more or less hand to a Java compiler for static validation. Does something like this already exist? Any other ideas? Any comments, explanations, wild ideas or pointers to additional material very much appreciated!

Re: A 1.5 release date?
Hi Peter, I'll just weigh in with a quick comment or two as I'm working through the weekend to deliver a big project next week. I may not be able to respond later as my email access is limited. We've discussed this on the list before. My take -- Velocity is a mature product, with a released version in use lots of places. For 1.5 we focused on bug fixes (and improvements in error reporting, integration, etc) and it's pretty stable. There's really no important bugs left that haven't been solved-- Look at JIRA and look at the wiki -- there's only a handful of trivial (if subtle) syntax bugs left. (there's an irritating problem with including macros in parsed files too, but it's arguable whether that's a bug or design issue). User support is pretty good -- the lists have far more activity than a classic dormant project. And developers are still around. (Myself, Nathan, Henning are often present on the lists). The major frustration continues to be release - understandably many users expect a released version and we haven't delivered it in a timely manner. Regardless of this fact, there's many users using version 1.4 and some using pre-release 1.5. The software hasn't decayed, it's only gotten better. I don't feel competitive. Everyone has to make their own decisions about whether and how to use Velocity. Like Nathan, I also feel bad about the lack of a release. A week of work and it would be done. But when I have my entire year's salary hanging onto the delivery of a consulting project in May and June, it's hard to set that time aside. The other committers also have significant work and family committments. (what's with all this family stuff, anyway?) I'm reluctant to say anything about timing in public, since I've been wrong before. But I'm betting that I'll have that week in the summer - maybe when I go on vacation :-) best, WILL Peter Harrison wrote: Velocity continues to be one of the primary technologies I use, but there are a few annoying bugs that have been planned for future releases and never made. The point is that without a tight release cycle a open source project will stagnate. The primary problem I see is that any work done in Velocity will not make a release version anytime soon. If I thought that improvements would make it into a release I would have fixed them by now in the original codebase. There are two major bugs I know of: 1. Setting a value to Null is ignored. Yes, I know its in the docs, its been discussed to death here, but has not seen a fix in years, eben though its a consensus that this should not be the right behaviour. . 2. Having a Null in the first object within a list will cause the method cache to fail, and that column will have empty values for every column. There is a nasty work around code in every view for these issues. I am not a newbie, have used Velocity for years, and continue to believe it is better than JSP. However, I would like to see active development, and I am prepared to help so long as I know that the work will actually be released. I'm not being critical for its own sake - I believe in Velocity, and my work depends on it. I would like to see it improved. I would like to take part in that improvement. But I need to know that those who control the process will release my work in a timely manner.

Re: Can velocity load a properties file ?
Hi Trad-Ex, Far be it from me to dictate how to develop your app. But I tend to avoid reflection in Velocity for the following reasons: -- It's a complex syntax, easy to mess up, hard to read, hard to debug. -- There's a much simpler alternative (putting objects and methods directly in the context). -- This is actively dangerous for cases in which third parties submit templates as they have full acess to files and other resources on your machine Velocity works well as a markup language where text is directly inserted in a template via properties or method calls. Such templates are easy to use and easy to maintain. If you need a scripting or programming language there are much better alternatives. best, WILL On 4/20/06, trad-ex [EMAIL PROTECTED] wrote: Hi Barbara, Hi Will, Thanks a lot for your response.

This has forced me to a more general solution, where I have a
ResouceLoader
which is a decorator to any other and takes the InputStream returned,
converts it to a String, does Perl5 substitutions on it and then
converts the String back to an InputStream.
My code is at work but from memory I do something like
public abstract class WebMacroResourceLoader extends ResourceLoader {
private ResourceLoader loader ;
public void init( ExtendedProperties configuration) {
loader.init(configuration);
}
public InputStream getResourceStream(String templateName) {

// return new input stream
} else
return loader.getResourceStream(templateName);

this.loader = new ClasspathResourceLoader();
}
}
public class WebMacroFileResourceLoader extends WebMacroResourceLoader {

Re: Switching from PHP to Java/Velocity, Performance?
One of the things I like about Hibernate is that it has request-level caching automatically. In other words if you read and write to the database within a single request, that will only hit the database once. It also organizes queries and minimize them. Another point - if you do clustering you might consider a stateless app. (This is very common for PHP). This solves a lot of the session cluster problems.

Re: Switching from PHP to Java/Velocity, Performance?
Stateless means that there is no in-memory user session. Track the user id in a cookie and retrieve any relevant info from the database each request based on the user id and URL parameters. This works well for simple apps which don't need to remember much info from page to page (I think of Flickr where most stuff is driven by URLs). The advantage of that without a user session in memory, you can send the user request to any server in your cluster. Not a requirement (there's other ways to handle this problem) but just an idea. You'll still need to use a cluster-based cache for database queries. This is where a lot of the performance savings can come in. Possibly you'd use an abstraction layer (like Spring or Hibernate) that will let you change cache systems from a single server cache to a clustered cache when you need to.

Re: Switching from PHP to Java/Velocity, Performance?
Hi Dominik, Wow, that's a busy site. The short answer is that writing a high performance application is mostly about architecture and only partially about language. If you read the pages and pages of comments on that famous post, the intelligent comments mostly boil down to that response. Caching is critical, (for both database queries and page generation), as is good database design. Velocity is unlikely to be a significant part of your bottleneck as performance with template caching turned on is quite fast.

Oh, no. Here come the religious arguments. Although you'll likely find more Java than PHP programmers on this list! To be fair, although I'm a Java programmer I attended a compelling presentation on designing scalable apps with PHP. (Taught by Cal Henderson of Flickr). So, I'm wary of blanket statements condemning scripting languages or PHP. http://www.carsonworkshops.com/dev/henderson/20JUN2005_photos.html Anyone have good practical resources/articles on scalable web app design to point Dominik towards? WILL On 4/12/06, Peter Harrison [EMAIL PROTECTED] wrote: Dominik Bruhn wrote: Hy Will, thanks to your response. My question was not only concerning Velocity but also about Java in General in Comparison to PHP. I hope that there are some Developers who have user Java and Velocity in realy huge sites. You must also consider complexity. If you have a site which is simple then PHP will probably be fine, even under heavy load. However, if your application is complex then Java shows its mettle. You *can* write nice PHP code, but it requires a disciplined developer. You can also write horrible Java code, although its less permissive about what it allows at compile time (strong typing). The point is that each language has its role, and I think blanket statements like PHP is not a language are not helpful. Python for example is a great language, and we have used it several times to develop quick solutions that would have been substantially more difficult in Java. However, with the infrastructure around Java/Struts/Velocity the actual code you have to write is greatly reduced, and whats left is simplified. For web apps Java/Tomcat/Struts/Velocity remains a credible and effective solution. The downside to Java I feel is a pretty long learning curve compared to other languages. It is certainly more verbose, and has quite a few elements that make life complex. PHP and Python on the other hand have not developed the same infrastructure to date, although if you want a CMS there are many options that will be a good start. As for performance, I must agree that performance is a question of architecture and complexity. Complex applications will be slower because they need more DB time and more CPU. The best way to handle this is - as a previous poster said, keep everything cached where possible, hit the db the least possible, and keep the architecture open so you can deploy multiple web servers as part of a cluster. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Forio Business Simulations Will Glass-Husain [EMAIL PROTECTED] www.forio.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: using Velocity in an untrusted environment
Hi Ben, You probably don't have an issue with #include though it depends how you organize the templates. In our case, I load templates specific to a given user via part of the path, e.g. /will/abc.htm. Hence we needed an event handler to decide if you have permission to include the files or not. If you don't indicate user specific info on the path you're likely ok. It's probably pretty obvious whether this is the case or not. In regards to unescaped HTML, do a Google search on Cross-Site Scripting. Esentially, the issue is that if user A can insert text that appears on User B's screen, you need to prevent that text from including arbitrary HTML or JavaScript. The easiest way to do this is to convert all entities (e.g. into lt;). I'll have to think about the rendering cost issue. I agree with Nathan in that I'm reluctant to add a lot of complexity to the core to address this. I suggest either putting such code in a custom plugin (e.g. the ReferenceInsertEventHandler) that checks for resource activity and throws a RuntimeException if appropriate, or adding such a routine externally to Velocity in some type of thread handler. (e.g. it launches Velocity in a thread and kills the thread if it takes too long -- is that possible? I'm not a thread guru). Best, WILL On 4/6/06, Ben [EMAIL PROTECTED] wrote: Thanks Will, I appreciate your response. Two more questions though, in my project the templates are kept inside a MySQL database and are loaded by a custom class from there, does this mean I don't have to worry about the #include and the #parse loading another user's templates, since they only load them from a directory on the hard-drive? Also I dont' fully understand the problem of unescaped HTML inside the templates, what kind of issues can be expected from that in my case, where users are allowed to upload their own templates anyway, or it only applies in a case where they don't have permission to do this? I'll be happy to share my solution about interrupting the rendering process, if I come up with a generic way which can be applied to other projects besides mine. Ideally I would like this to be a function of Velocity itself, where for every operation it does it would assign some number, which would be the cost of that operation, and then the developer would have the ability to set the maximum cost, after which velocity would automatically interrupt the rendering process. Another option would be for it to save the starting date/time of the rendering process, and then every now and then to check how much time has passes, and if the time limit has expired to interrupt the rendering process. I am not sure I have sufficient understanding of the Velocity source code to do this though, can anybody who knows the Velocity code well tell me if any of these two options are feasable, and if yes, what class/classes would I need to modify for this?

It works pretty well. We've tried to address most security-related issues, but so far we've just ignored the potential DenialOfService issue and haven't had any trouble. As far as the classloader patch goes, you can put it into a custom Uberspector and use it right now. A little complicated, but it works. Some of the other items in the article have been fixed. The current source control head contains an Event Handler which can automatically escape HTML. There's also a new event handler that can be used to modify #include and #parse (say, to prevent one user from including files of another user). In Tomcat you can set up catalina.policy to restrict access to files outside the webapp using the Java security manager. It takes a little trial and error to get this right. Most third-party libraries (e.g. Velocity, Hibernate, etc.) require certain permissions and these are almost never documented. I can share mine if that's helpful although it's pretty specific to my apps. Finally, you need to be very careful as to what you put in the context.

Thanks - let us know what you find... On 4/6/06, Ben [EMAIL PROTECTED] wrote: Thanks for pointing the way, I'll definitely take a look at the SimpleNode class and see if it can be used for my purpose. I don't want to use a separate thread since by me the render function is called from within a servlet running inside resin, so what i'll probably do is have it check the time, let's say every 10,000/100,000/1,000,000 loops or so, depending on how many loops it does per second, and if it's past the time limit stop the render process, or maybe just limit the rendering process to a certain amount of loops, to prevent people from writing templates with a near infinite loop. I do some work with Yahoo's RTML scripting language, which is being interpreted by a perl script running on Yahoo's servers, and I think that's what Yahoo does, limit the loops to 10,000,000 iterations or so. If people are interested I can paste the results of my experiment when I am done, as well as any modifications I make. Hmm. To be honest, I'm not interested in having this be an out-of-the-box piece of Velocity. Adding this maximum cost option for every operation it does would mean a performance hit, a big rise in complexity, or both. I would want to see a lot of interest in this from others before i would let this change go through without vetoing it. I really don't think this is something most of our users want or need. No one else has asked for it (to my memory) in the five years i've been around. For you, however, it ought to be fairly easy straightforward to create a VelocityRunnable that you can start in a new Thread to do the template merge/render and then have the request thread check up on it (sleeping in between checks, of course) periodically. The tricky part is stopping the rendering thread when it goes over time. It's not really safe to use the deprecated Thread.stop() method. The recommended replacement (http://java.sun.com/j2se/1.4.2/docs/guide/misc/threadPrimitiveDeprecation.html) is to create velocityRunnable.stop() method that can flip a flag to interrupt the rendering. But Velocity doesn't have any built in way to *interrupt* the rendering. The only thing i'm aware of is the #stop directives ability to make Velocity stop sending output to the writer. So far as i know, it doesn't actually stop the template processing (personally, i think it'd be better if it did). To actually stop template processing, you will probably have to alter some of the internals yourself. The driver of the rendering process is a simple for() loop in the render(context, writer) method of the SimpleNode class. all the nodes extend this class, so this method is how the AST is traversed. I would imagine that the real way to do this would be to somehow put the flag in that for() loop's conditional that would be shared by all nodes in that template. That probably means you need a flag that resides in the context that's being passed around. When the flag is tripped, no further nodes should be rendered. Of course, i'm not 100% sure that that is all you'll need to change, and it also might not catch all possible problems. For instance, if it is the rendering of a particular leaf on the AST that is taking forever, then this won't stop that node's rendering; it would only stop further traversal of the tree. Still, that is hopefully enough info to get you started... - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Forio Business Simulations Will Glass-Husain [EMAIL PROTECTED] www.forio.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: confusion regarding velocity versions...
Whoops! The home page is wrong. The current version is 1.4. The patch is in the as-yet-unreleased-1.5 (along with numerous other new features). This can be downloaded (source) at http://svn.apache.org/snapshots/jakarta-velocity/ For info on building, see http://jakarta.apache.org/velocity/build.html And feel free to ask for help on the list.

Le mercredi 15 mars 2006 à 11:07 +0100, Holger Willebrandt a écrit :
Hello everybody,
i would like to parse a velocity template and collect information about
all variables that are used within it.
Therefore, i use the Parser class in the following way:
//here a reader for the template and a collector for the variables
//will be supplied
public static void findVariables(Reader reader, List collector)
throws ParseException {
VelocityCharStream cstream = new VelocityCharStream(reader, 0, 0);
Parser parser = new Parser(cstream);
findVariables(parser.process(), collector); //call method below
}
//this method will recursively collect the variables and store them
//in the collector.
public static void findVariables(Node startNode, List collector) {
if (startNode.getClass().equals(ASTReference.class)) {
if (!collector.contains(startNode.literal())) {
collector.add(startNode.literal());
}
}
for (int i = 0; i startNode.jjtGetNumChildren(); i++) {
findVariables(startNode.jjtGetChild(i), collector);
}
}
The code is working as long as the template does not contain a #foreach
statement.
Whenever i try to parse velocity code with a #foreach, i get the
following error:
java.lang.NullPointerException
at org.apache.velocity.runtime.parser.Parser.Directive(
Parser.java:628)
at org.apache.velocity.runtime.parser.Parser.Statement(
Parser.java:319)
at org.apache.velocity.runtime.parser.Parser.process(
Parser.java:258)
Looking into velocity's source code, revealed that the Parser is missing
a
RuntimeServices instance, resp. a template name.
It would be nice to have a way of collecting all variables and
validating the
synatx (a ParseException would indicate a syntax error) at once.
Any kind of help or advice is welcome.
Thanks, Holger

Re: Features
Hey, just a quick comment. Check the velocity-user archives for extensive velocity versus freemarker conversation. This has been hashed to death here in previous months... might be more productive to take the FreeMarker specific part of the conversation to the FreeMarker list. WILL On 3/10/06, jian chen [EMAIL PROTECTED] wrote: Hi, Jonathan, I am a bit sad to see that the Velocity project hasn't been that active these days, particularly with the much needed enhancements still pending. However, I just don't like FreeMarker for the following major reasons: 1) FreeMarker tags look similar as html tags. 2) Too much feature in FreeMarker. The template engine language should be succinct. Otherwise, it might give people too much flexibility in templating. I would hope to have a better version of Velocity though, with the bug fixes and correct feature enhancements.

Last night i looked at source to see how to simply implement those new features, but it seems it will not be as easy as i thought. The fact is that if nobody even gives you any pointers as to where to look, where the crucial points in the code are, it's not generally going to be easy. Some people are surely better at this than others, but I personally find it very hard to get into an unfamiliar codebase and understand the mind behind it. I think it's only fair to tell you and anybody else interested in having macros work this way, that this is already available in FreeMarker. For example, if I define a macro as follows: #macro foo bar baz=some default value ... /#macro it can be invoked with either one or two arguments. The baz argument reverts to the default value when it is invoked with just one argument. Macros with can be invoked with the parameters by name, as in: @foo bar=arg1 baz=arg2/ If I listed all the other other goodies in FreeMarker's macro system that are not present in Velocity, this message would get quite long. See: http://freemarker.org/docs/dgui_misc_userdefdir.html These features have been present in FreeMarker for 3 years or more and many people use this stuff in production and it is highly stress tested. An existing mature tool that already has the features you want is likley to be a better technical solution.

Re: problem loading templates
A snapshot of the (unreleased) Velocity 1.5 code is available here. http://svn.apache.org/snapshots/jakarta-velocity/ (I notice the link on the website is wrong - I'll fix that). You'll need to install ant and type ant build after cd'ing to the build directory. You can also access the source code with Subversion (svn).

Re: PANIC : Velocity cannot find any of the specified or default logging ...
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.
