Re: Multi-dimensional arrays, velocimacros, and navigation menu lists
Hi Chris, Does VTL support multi-dimensional arrays (e.g. an array of arrays) and what would be the syntax to access values stored in them? I've been looking around (googling, Velocity user + developer guides, Gradecki's book) but can't seem to find anything dealing with this sort of thing - maybe because its not possible? It doesn't support arrays other than in the #foreach directive, but you can use ListTool. http://jakarta.apache.org/velocity/user-guide.html#Loops http://wiki.apache.org/jakarta-velocity/ListTool The reason I ask is: I want to be able to write a velocimacro to construct a navigation menu and add a class to a selected list item to highlight the current page. A sample menu in HTML might look like this: map id=menu title=Site navigation ul li class=selecteda href=Menu Item 1/a/li lia href=Menu Item 2/a ul class=subnav lia href=Sub-Menu Item 1/a/li lia href=Sub-Menu Item 2/a/li /ul /li lia href=Menu Item 3/a/li /ul /map At the top of the each page would be a velocity #set directive like this: #set ( $pageID = menu_item_1 ) What I had in mind was writing a velocimacro which would iterate through each item of a supplied array, performing some kind of test (not worked out yet) to see whether it matches $pageID, then writing out the list items (with the class=selected if necessary) Any ideas or suggestions? Your help is, as always, very much appreciated. I guess we can start with what you have now. Doesn't seem like it shouldn't work.

Re: Passing Variables through velocity
Hi Jonathan, Hi. I'm a bit new to Velocity and Java. I've been reading all the docs online, but I'm stuck at this one point. I'm trying to pass a variable off from the build.xml I'm using to my site.vtl file (using the Anakia example). I'm using the command line 'ant -Dfilename=getrel'. Filename is the variable I have set in my build.xml and the variable I'm setting to getrel. I want to be able to pass the variable off to my site.vtl where I can then work with it within the .vtl file for a #foreach and an #if statement. I don't think there's a way to get a string into the Anakia Context, but you might want to check out Customizing the Anakia Context. http://jakarta.apache.org/velocity/anakia.html#Customizing%20the%20Anakia%20Context Best regards, -- Shinobu -- Shinobu Kawai [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Have a strange problem
Hi Paul, I have developed my web app in windows using net beans 4.1 and its included webserver (tomcat 5.5.7). Under the NetBeans webserver my web app works fine. When I took the war file that was created by the NetBeans program and placed it into my Linux Tomcat server (Tomcat 5.0.27-9) I got a VelocityViewServlet Exception ## snip I think the problem is that the page is looking for my properties file and can't find it. What I don't understand is how it works in one version of tomcat and it doesnn't in another? Any suggestions? The web app has to work on a 2.3 spec tomcat at least. That puzzles me, too.

Re: velocity error page
Hi Michael,
I've been trying to make a velocity error page but I've been having some
troubles. The correct velocity template gets displayed but the error
information doesn't seem to be in the request. For example the
attribute ${errorData.statusCode} and/or
${pageContext.errorData.throwable}appear in the page literally without
displaying their correct values. The same page written as a jsp using
jstl and EL works fine but I'd like to avoid using a mixed environment
of jsp and vm. Is there something else I have to do to pass those
values to the template?
errorData/pageContext is a JSP thing. It doesn't apply to general
view components.
BUT, as stated in the servlet specs (SRV 9.9.1), corresponding request
attributes are set. You should be able to get them via the request.
$request.getAttribute(javax.servlet.error.status_code)
It might be a nice RFE to have them easily accessible to the Context,
though. ;)

Re: classloading
Hi max, I'm talking about FieldMethodizer RuntimeInstance LogManager ResourceManagerImpl ResourceLoaderFactory Generator I guess you can start by filing an issue. :) http://issues.apache.org/bugzilla/enter_bug.cgi?product=Velocity While on the subject of things that messes up J2EE/Eclipse environments. Why is so much stuff logged as WARN/ERROR in Velocity ? Like: ERROR: ResourceManager : unable to find resource 'VM_global_library.vm' in any resource loader. That should at least only be a WARN and it should be in a ResourceManager category so you could disable it. Solved in the repository. http://issues.apache.org/bugzilla/show_bug.cgi?id=9938 And: Warning! The iterative is an Iterator in the #foreach() loop at [0,0] in template pojo/javaclass.vm. Because it's not resetable, if used in more than once, this may lead to unexpected results. Again, I undestand why this is there - but it should only be done on objects that is directly in the context (if at all). Printing out this warning for every iterator is simply not very usefull... e.g. printing this warning for a methodcall that does someList.iterator() is just noise. I removed this last one by providing my own UberSpectImpl, but it should not be necessary IMO.

Re: NullPointerException problem
Hi Paul, I have written a few java files and rewrote a template to be more like a template rather then standard html. When I tried to view the webpage I found that I have a NullPointerException. Usually when there is a NPE the compiler tells me where in my code the NPE is coming from. However it just starts out with org.apache.velocity.tools.struts.StrutsUtils.getMessageResources(StrutsUtils.java:211) Source says, you didn't give it a ServletContext, or a ModuleConfig could not be found. return (MessageResources)app.getAttribute(Globals.MESSAGES_KEY + moduleConfig.getPrefix()); I think the problem is that the properties file I defined is not moved to the classes directory when the javacode is compiled. How do I do that if I am using Ant to compiule my source code? However when I did move the properties file into the right directory, I still get the same error. Oh yeah this happens on all velocity pages that I created before I changed the code. If you need to see the entire error please let me know and I will provide it. I think it would.

Re: compare float?
Hi Nick, 1) We have been using velocity 1.3.1-rc2 and have a requirement where we need to compare floats in velocity templates. So we need to do something like #set($afloat=$floatObject.gpa) #set($gpaWarning = 2.7) #if ($afloat = $gpaWarning) academic probation letter Can this be done in 1.5-dev? If we need to put the gpaWarning value into context, we can do that if it cannot be declared in the template. Is that needed? Yes it can, so no it's not. As an alternative, you can create a $floatObject.isGpaUnderWarningValue() method. :) 2) We have quite a bit of code that depends on 1.3.1-rc2, is 1.5-dev in a stable state?

Re: IteratorTool question
Hi JohnE, I am wondering if you can help me with a looping question. I looked through the user forum and found a good example by Shinobu. In trying to duplicate it, I am getting odd results. My use is below: #set ($wrapper = $iteratorWrap.wrap($largeCollectionOfStuff)) #foreach ($item in $wrapper) #if ($velocityCount = $endingRecord) $wrapper.stop() #elseif ($velocityCount = $beginningRecord) $item.toString() #end #end This seems pretty straight forward, but using it as such only causes one item to print out once. It only executes the foreach once. When I place $wrapper.more() before the last #end, it causes it to cycle through all of the records but it also causes the records to print out. I do not want a print out. more() needs to be called in order to go forward. You can do something like #set($garbage = $wrapper.more()) to not print the result. But maybe a wantMore() will be a good RFE. ;) Also I am wondering how a continue might be handled. I am not very sure how velocity parsing would be handled if it has to parse to the last #end on each loop when the #end can be past lots of logic.I would think having not just a #stop (aka break) would be useful, but a #continue. Actually, #stop stops Velocity, not just #foreach. Using #if is the only solution for a continue that I can think of right now. http://jakarta.apache.org/velocity/user-guide.html#Stop Best regards, -- Shinobu -- Shinobu Kawai [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: A couple of wording suggestions

I'm not sure that's grammatically correct, and a colleague of mine suggests changing the end to: ...same number of arguments as in its definition. I had considered simply inserting as before the final with as an alternative, but that may be a little cumbersome. 2) In the Case Substitution section, there is a sentence ending: ...its developers have strove to catch and correct user errors wherever possible. We believe have strove is incorrect and should either simply be strove (i.e., removing the have; though that does change the tense) or more likely should be have striven.

Depending on the environment, I think the browser will cache the jars, making it faster to load from the second time. 2. applet with package I build a applet class with package. and then place it into a corresponding folder in WEB-INF/classes/ Such applet tag in a velocity template will not work anymore: table cellpadding=0 cellspacing=0 border=0 width=808 APPLET CODEBASE='$content.getURI (WEB-INF/classes/com/correspondingclassfolder/)' code = 'CustomObject.class' WIDTH = 300 HEIGHT = 300 /APPLET /table It will be such 'ClassNoFound' error. So, my bottom line question is how to integrate applet class into the velocity page, where to put it. Applets are client-side technology. So it will not have access to the unexposed WEB-INF directory. I suggest you put what is needed by the applet in a jar and refer to it with the archive attribute like in 1.

Re: applet
Hi jill, I moved Star.class to the folder where the template sits. And change the applet tag to table cellpadding=0 cellspacing=0 border=0 width=808 APPLET CODE='Star.class' WIDTH = 300 HEIGHT = 300 /APPLET /table The message from Jave Console is like: ## snip java.lang.ClassFormatError: Star (Bad magic number) Something definitely messed up your class file. http://java.sun.com/j2se/1.4.2/docs/api/java/lang/ClassFormatError.html I suggest that you first test your applet without Velocity, and move on to Velocity once you get it working.

Re: cactus and velocity
Hi Rob, I want to use Cactus to test some filters that are mapped to velocity pages. It is working for the most part. The problem is in the endXXX methods and the WebResponse object (both Cactus default and HttpUnit). They never return any text -- using webResponse.getText() is always empty. The WebResponse object does return the status code as 200 and that the response contentType as correct (text/html). Are there any tricks to get the response to include the velocity rendered page?

Re: Ifnotnull
Hi jeichels,
I had previously upgraded to 1.5-dev and things are working well with the one
email templating thing I had found help here on.
Since the upgrade, however, I seem to be getting some RHS of #set statement
is null. things i don't remember getting before.
I explored a bit and found:
http://wiki.apache.org/jakarta-velocity/CheckingForNull
I added these to my velocity property file:
userdirective = org.apache.velocity.tools.generic.directive.Ifnull
userdirective = org.apache.velocity.tools.generic.directive.Ifnotnull
## Wow! First person I've heard using it!
And changed my template code as follows:
#ifnotnull( $form )
#set ($attr = $form.getBean())
#end
And get this error:
Encountered #end\r\n at line 3, column 1. Was expecting one of: ( ... ...
... ... ... \\ ... ... ... *# ... *# ... ... ... ... ... ... ...
... ... ... ... { ... } ...
org.apache.velocity.exception.ParseErrorException: Encountered #end\r\n at
line 3, column 1.
The error suggests that you aren't configuring the directive
correctly. Have you added it to your codebase/classpath?

Re: Ifnotnull
Hi JohnE, I like velocity very much, but I do not like its handling of null in general. I do not want to have to put a isNull check into every object being checked. This at least seems a somewhat straight forward directive. I am not sure how efficient it is in comparison to the other methods of checking and efficiency is important always. Performance never bugged me, but any benchmarks results are welcome. :) In terms of configuring, I have very recent Velocity and Velocity Tools from Subversion. Besides that, all I did was do what the link directed me to do which was to put in those two properties in the velocity.properties file. Should I do something else? If so maybe the document should be updated? You need to actually compile the directive and put it in your class path. It's not part of VelocityTools. http://wiki.apache.org/jakarta-velocity/IfNullDirective http://wiki.apache.org/jakarta-velocity/IfNotNullDirective Also maybe you can mention something on performance and whether this is a good way to go about it all. There were like five ways mentioned. As I said, performance never bugged me, but my otherwise comments are written in the Note:s for each approach. In your case, I think approach #1 might do best. #if( $form ) #set ($attr = $form.getBean()) #end Best regards, -- Shinobu -- Shinobu Kawai [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: byte order mark and InputStreamReader problem
Hi Jian, I created a template in UTF8 encoding on my windows machine. When I rendered it on the web, the browser connected to the server fine but then it waited infinitely. I then modified the problematic template and got rid of the byte order mark (BOM) at the very beginning of the template. This time, the page loaded successfully in the browser. What I am getting at is, Velocity uses java.io.InputStreamReader, and given UTF8 encoding, the InputStreamReader does not handle the byte order mark. I also read somewhere that this problem of not able to handle BOM has been a long standing bug with JDK implementation. Now, just want to know you guys idea if Velocity should be hacked to use a custom-made InputStreamReader that could open the file, detect the encoding, and discard the byte order mark, if applicable.

Re: how to set null value
Hi Jian,
Thanks for sending me the useful information. After much
investigation, I plan to do the following hack for setting null value
in the context:
1) In the ASTSetDirective, in the render method, comment out the if block
if ( value == null)
{
Basically, this will allow the set null process to go ahread.
2) in the AbstractContext, remove the key from the context if the
value to be set is null:
else if (value == null)
{
this.internalRemove(key);
return null;
}
So, this should remove the variable in the context if it is assigned a
null value,
I believe so.
and it will be consistent with future release in Velocity,
right?
Can't be sure about that. The community has not yet reached consensus
on what to do with this issue.

Re: out of memory error using GZIPOutputStream
Hi Jian,
I have the following GZIPOutputStream on top of the servlet response
outputstrream to render the html to the browser.
String encodings = req.getHeader(Accept-Encoding);
if (encodings != null encodings.indexOf(gzip) != -1) // GZIP
{
resp.setHeader(Content-Encoding, gzip);
GZIPOutputStream gos = new GZIPOutputStream(resp.getOutputStream());
OutputStreamWriter out = new OutputStreamWriter(gos, UTF8);
evaluate(template, ctx, out);
out.flush();
gos.finish();
}
else // No compression
{
resp.setCharacterEncoding(UTF8);
evaluate(template, ctx, resp.getWriter());
}
## Are you sure the flush() and finish() should be in that order?
So, when the velocity template page is huge, then, I get a out of memory
error.
Also, this only happens when the server uses GZIPOutputStream (i.e,
the browser accepts GZIP). If I comment out the if () block so to use
no compression, the response is streamed back to the browser and there
is no problem.
Any ideas?
Will it fail on the first time? If not, maybe you aren't releasing
some resources.
Does increasing your memory solve your problem? If not, maybe there's
something wrong with GOS (like an infinite loop).
I suggest running it on a profiler and see who's taking up all that memory.

Re: velocity config.getInitParameter()
Hi Andrew,
I'm having some trouble getting a Velocity Servlet to read an init-param
from tomcat. So far i've tried the following:
public class SiteStructure extends VelocityServlet{
First, I suggest using VelocityViewServlet, as VelocityServlet is
deprecated and will be removed in future versions.
http://jakarta.apache.org/velocity/tools/view/index.html
private String base_dir = null;
protected Properties loadConfiguration(ServletConfig config) throws
IOException,FileNotFoundException{
...
String path = config.getServletContext().getRealPath(/);
this.base_dir = config.getInitParameter(basedir);
...
}
in my web.xml file i've tried these two options, although not at the same
time.
init-param
param-namebasedir/param-name
param-valuetest/param-value
/init-param
context-param
param-namebasedir/param-name
param-valuetest/param-value
/context-param
Its probably quite simple but i've looked all through both my tomcat books and
velocity books and i can't see any examples of this being done. The velocity
docs say that the loadConfiguration() is called from init(), which is where
all of the Tomcat servlet examples have called the getInitParameter() method
from.
I don't see anything wrong so far, but I can't tell until I see all
the relevant code. Does it work with a regular servlet?

Re: Velocity security
Hi Tony, I had a bit of a fiddle with Velocity a while back, and I'm considering using it in a J2EE project that is coming up. A requirement that I have is that users should be able to submit their preferred format for rendering of their web page, for which I thought Velocity would be entirely appropriate. :) The issue I have is security-related. I had a look through the Velocity user guide and the only real potential hole that I see is the use of the #parse or #include directive. I shouldn't expect users will use this, but I need to protect against it nonetheless (are there any other potential holes that I can't see?). I'll let you answer what risks you are considering to Malcolm. ;) The user document talks about the 'TEMPLATE_ROOT' (what is that exactly?) being the only place from which the referenced files can be included/parsed, The so-called 'TEMPLATE_ROOT' refers to wherever the ResourceLoader looks for templates. It will depend on how you configure Velocity. http://jakarta.apache.org/velocity/developer-guide.html#FAQ2 eg, if you use VelocityViewServlet, it will be the root directory of your webapp. http://jakarta.apache.org/velocity/tools/view/index.html I guess you could subclass VVS in VelocityTools 1.2-dev and create a one-VelocityEngine-per-user servlet to handle your requests. but I'm wondering if Velocity provides something to solve what I believe would be a common problem, perhaps by preventing include/parse directives altogether - or perhaps some unforeseen solution that is more wll suited.

But I want to *replace* $foo with another template code. for example something like: ## snip Ok, when I return it as a String (the second template code) it gets printed, but when in VelocityContext I have an Array under key list. So I think it must be generate a dynamic table in my case, but it only prints the template code as a String. So is there no way to relpase a Velocity expression/statement (e.g. $foo) with an other template code? I'm not sure how you're using the EventCartridge, but might the (View)RenderTool help? Well, at least the source for it should. ;) http://jakarta.apache.org/velocity/tools/javadoc/org/apache/velocity/tools/generic/RenderTool.html http://jakarta.apache.org/velocity/tools/view/ViewRenderTool.html Best regards, -- Shinobu -- Shinobu Kawai [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: ADD Function in Velocity
Hi Sashi, I am trying to use add functionality with external data #set ( $value = $templet.getLongValue() ) suppose now $value has value of 1 #set ( $value = $value + 1 ) Still the total shows 1. Actually its not adding value . Here $templet.getLongValue() returns a long Value Long arithmetic gets supported from Velocity 1.5.

Re: Using foreach loops on String[][]
Hi Jason, I didn't see this in the Velocity documentation but can string arrays of string arrays be iterated through via typical foreach handling or is it necessary to enumerate everything out. On that note, if I use Arrays.asList(String[][]) to put a List into the context, can I then access the individual String arrays as $Foo[0] $Foo[1]? Is there a difference between your phrases iterated through and enumerate everything out? To me, it sounds the same, and yes, I believe you can nest #foreach loops for that purpose. As for getting the elements directly, check out the ListTool. :) http://wiki.apache.org/jakarta-velocity/ListTool Best regards, -- Shinobu -- Shinobu Kawai [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: instanceof
Hi Ross, Does anyone know of a way to do instanceof checks from VTL? At the moment I'm providing a simple isA method on objects, but I am thinking there must be another way... The isA method works, but (at the moment) only checks the actual classname (not superclasses). Before I go about working this out, I just wondered if I had missed something crucial ... ? None in Velocity, but I'll bet you can make a tool that does that. ;) Best regards, -- Shinobu -- Shinobu Kawai [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Map creation outside of #set
Hi adam,
I really need the ability to define a Map outside of a #set. For instance:
$form.select('model.property', { 'onChange' : 'doSomethingCool()',
'style' : 'color: red' })
Right now, with what is in cvs (when is 1.5 going to be released,
btw?), as far as I can tell, I have to do this:
#set($attrs = { 'onChange' : 'doSomethingCool()', 'style' : 'color: red' })
$form.select('model.property', $attrs)
Ugh.
Please tell me I am wrong. I looked at the Velocity source, and I am
99.9% certain that I am not. How hard would it be to get this? Maybe
the real question should be, why doesn't Velocity have this already?

Re: Problem with decimal in most recent snapshot
Hi JohnE, Basically I am getting a decimal when I should be getting an int with the following code I use in production already: #set ($colSize = ($jpPop.size() / 3) - 1) THE COLUMN SIZE IS $colSize when colSize is printed out it gives a number like 6.333 when all values in this calculation are integer. I should get 6 as an int according to the documentation. The User Guide says: When a division operation is performed between two integers, the result will be an integer. http://jakarta.apache.org/velocity/user-guide.html#Math The MathUtils#divide javadoc says: Integer-types will be returned as Integer-type if and only if the modulo of the two numbers is 0. http://svn.apache.org/repos/asf/jakarta/velocity/trunk/src/java/org/apache/velocity/runtime/parser/node/MathUtils.java They can't both be right. If you consider backward compatibility, the user guide should be correct. But my mind says the javadoc is more convenient... Will? cf. http://issues.apache.org/bugzilla/show_bug.cgi?id=25874 http://mail-archives.eu.apache.org/mod_mbox/jakarta-velocity-dev/200501.mbox/[EMAIL PROTECTED] From what I can see there is no way to make a float an integer either. This too I would imagine could be a problem. For now, you can use the MathTool. http://jakarta.apache.org/velocity/tools/generic/MathTool.html#toInteger() I was hoping to push this into production tonight but it will have to wait till I can figure out what to do with the potential affects this could have to the whole system or...it gets resolved.

Re: Streaming from the middle of a template?
Hi Evan, Here's what I'm doing: I've written a reusable html-control model for creating html components within the struts framework using velocity. These components use velocity themselves to render their content. These controls may also themselves contain other sub-controls, and so on. It seems ineffecient for me for each of these sub-controls, to have to create a single large string and return it to its parent control to render it. I would rather pass a writer down through the execution hierarchy having each subcontrol add its output to the parents writer, thus using a single writer to achieve the total output, instead of a segmented writer.toString - writer.toString - writer.toString sort of process. Does that make more sense? If all the components uses Velocity to render the content, you must be using Template#merge or Velocity(Engine)#mergeTemplate or Velocity(Engine)#evaluate in each of your components, correct? If so, you can just put the Writer in the Context before rendering. context.put(writer, writer) And in the template, $component.render($writer) Best regards, -- Shinobu -- Shinobu Kawai [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Loading templates from classpath
Hi seba, I am in the following situation: I'm running a Velocity servlet in Jetty, and everything works fine until I load the template (which Velocity can't found). I would like getTemplate() to load the template from the classpath (i.e., from the jar file), so to have a completely self-contained application.

Re: Loading templates from classpath
Hi seba, Let's keep it on the list. No secrets. ;) My problem is that I would like to set the loader programmatically. I do not want to set up web.xml or similar. I just want to start jetty and have the servlet initialisation code (or whatever initialisation code must be) set the loader to the ClasspathResourceLoader, and finally have templates read from the jar. If you aren't going to customise your web.xml, how are you going to let the servlet container know which servlet to use? Or am I missing something about jetty? Anyways, _if_ you're willing to edit your web.xml, it's as simple as setting your velocity.properties. http://jakarta.apache.org/velocity/tools/view/ I have the idea that this should be doable by overriding loadConfiguration() and setting something either in the Velocity runtime or in the properties obtained by super.loadConfiguration( config ). Again I could not find any examples about this. You got the picture!

Re: Loading templates from classpath
Hi seba,
You read my mind. 8^) Here's the catch: put this in the servlet.
protected Properties loadConfiguration( final ServletConfig config ) throws
FileNotFoundException, IOException {
Properties p = super.loadConfiguration( config );
p.setProperty( resource.loader, class );
p.setProperty( class.resource.loader.class,
ClasspathResourceLoader.class.getName() );
return p;
}
Thanks for sharing your solution with us! Maybe someday it'll get into the FAQ.
http://wiki.apache.org/jakarta-velocity/VelocityFAQ
## Anyone can update the wiki, BTW. B)
What was completely confusing me is that Velocity defines a number of
final static constant strings for properties, but apparently not for
*all* properties. class.resource.loader.class is not in, or I couldn't
find it. Anyway...
FYI, there's one for resource.loader. :)
