I'll leave it up to you. Did all tests pass too? Historical reasons are all i can think of right now. It is how it was done. I think, too, it was a way to keep out public methods inherited from protected classes. I kinda doubt the current dev community (myself included) would care about that anymore. I'm not sure whether there's much performance gain to be had by the swap, but certainly it seems like it would simplify the code and perhaps obviate such strange bugs as VELOCITY-736.

Re: Testing for nulls with #if
When the innards of the $val block ($item.get(1)) resolve to null,
they are output as they were. So $val should render as the literal
string $item.get(1). That string is definitely not null. If you
want, you can use quiet notation ($!item.get(1)), but even that will
render as an empty string , which is also not null. So, no matter
what, your $val reference will not be null. It is a defined block
object which never renders as null. It is not a workable shortcut for
null testing. You can do #if( $val == ) if you switch to quiet
notation or #if( $val == $item.get(1) ) to test properly as things
are.

Re: Problems using logging in Velocity 1.6.2
On Mon, Aug 24, 2009 at 4:12 PM, Dr. Matthias Lauxmatthias.l...@web.de wrote: Hi Nathan, thanks a lot! So indeed most messages are at the FINE level, just as suspected. The problem I'm trying to solve is to identify actual template problems such as FINE: Null reference [template 'release_main.vm', line 18, column 9] : $yyy cannot be resolved. (taken from a JDK log output based on JdkLogChute). This originates in ASTReference line 404-406, where log.debug() is called - as expected a FINE log message. One problem I see is that this message is hidden between zillions of other messages offering status information - but no indication of real problems. The message above shows a real problem I need to fix. If this came at a WARNING or SEVERE level, I could find it. This is a debated issue and more involved than you might think. Velocity's original creators designed it to ignore schmoo (defined as anything not intended to be replaced by Velocity). I believe the idea was to have Velocity be very unobtrusive and only replace things it clearly understood and had values for. The imagined workflow was that people would take content and insert VTL into it. In such a view, syntax errors and missing values are minor things to be expected and easy to ignore. Other template engines reverse that and assume that anything that looks like their particular syntax are intended to be so. Thus, any missing values or syntax errors are treated severely and must be made impossible to ignore. The imagined workflow here is that the template language is primary and the content inserted into it, rather than vice versa. The Velocity community has never been at one mind (to my knowledge) about which approach was better, leading to a variety of inconsistent escaping patterns and configuration options to bend it one way or the other. There was enough other work and debates going on that this one never gained clear consensus or careful control, but the ignore schmoo view has largely prevailed as the default, leaving stricter controls as config options. My early contributions to the Velocity Engine project were largely about enhancing and cleaning up the log system and output. At the time, consensus was that it was much too noisy for a library. So i lowered the levels on many things, including this one you are concerned with. I stand by that choice as fitting the default pattern of Velocity. If you wish to treat missing references more harshly, you are free to configure ReferenceInsertionEventHandlers to do so, or turn on the strict mode that Byron Foster added in 1.6 (see the Strict Reference section of http://velocity.apache.org/engine/releases/velocity-1.6.2/developer-guide.html ) . These features allow you to push Velocity into more of a content inserted into template syntax paradigm. But unfortunately there is no option that will only raise the log level of that message. Different LogChute implementations may map the level differently, but all should map it to something that indicates debug level, not error or warn. In my previous approach messages like this were preceeded by [warn] or [error] and could be easily found in the velocity.log file. This was based on using the Velocity class directly rather that VelocityEngine. Is there some way to reproduce this behaviour in the new approach? Sounds like I should try to use the SystemLogChute or the AvalonLogChute since both use LogChute.WARN_PREFIX, which is what I had seen before in the output.

In the past I used the Velocity directly such as Velocity.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, templateDir); Velocity.init(); and got the expected output in the velocity.log file. Now I moved to using VelocityEngine instead because I had some issues with the output in a long running server app which performed the same tasks over and over again (the velocity.log file would grow and I did not know how to get Velocity to start a new file for every processing run). Anyway. Now the new code started to look like this: engine = new VelocityEngine(); engine.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, templateDir); engine.init(); and nothing happens other than an empty file velocity.log being created. Well. So I added a LogChute: engine = new VelocityEngine(); engine.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, templateDir); engine.setProperty(RuntimeConstants.RUNTIME_LOG_LOGSYSTEM_CLASS, org.apache.velocity.runtime.log.JdkLogChute); engine.init(); because I'm using JDK logging in my app anyway. My own logging is based on a console handler with level INFO and a file handler with level FINE (at least right now). What happened now was that there was nothing related to Velocity on the console, and truckloads of FINE log entries in the file handler. That's not quite all of the expected results, but it's the best I got so far. As it seems, Velocity seems to pick up the settings of the JDK logging subsystem. It gets weird tho when I set the logging level for the file handler to INFO as well: all log entries to the file handler for the JdkLogChute are gone. The only way for me to understand these observations is that only log messages of level FINE are actually recorded. Even if I go to level FINEST and check out the log files afterwards, there's zillions of Velocity log entries, but all with level FINE. This works also for the java.util.logging.ConsoleHandler, i. e. setting the level to FINE there also gives me the log messages, but all of level FINE. In my original velocity.log there were - for the same set of data - [error] and [debug] entries which I would like to see again as corresponding log entries. Having only messages of level FINE can't be correct tho. When, for testing purposes, I add a manual log entry like this engine.getLog().info(Hello); right after the init(), it works on both console and file. So the loggers used inside Velocity also work correctly, but it seems that Velocity itself only creates log messages with level FINE - which I refuse to believe. I also tried the AvalonLogChute instead since that seems to be the default used in my previous implementation (velocity.log created by interacting with Velocity instead of VelocityEngine). Same result - an empty velocity.log file. Well, this is not too surprising since I presume that the AvalonLogChute is still the default - and I had not specified a LogChute in the first attempts. I'm kinda lost right now. I would like to be able to use JDK logging (since then I don't have to deal with different output files in analysis afterwards) and I would like to propagate the (configurable) log levels of my application to the

No, there was never such a feature.

Re: From Viewtool get the VTL being parsed
a tool can really only get access to whatever is in the context or
what is manually given to it. since the HttpServletRequest is
available automatically, they can get the request path and derive the
file from that. just know that even that isn't perfect; if the
request path points to foo.vm and foo.vm does #parse('bar.vm') which
is the one with your tool being used in it, there's no way for the
tool to know that without being told, since #parse doesn't really
inject info about itself into the context.

Hi,
Use $velocityCount in place where you need incremental value of some
variable
Eg: instead of,
#set($a = 0)
#foreach($mapping in $mappings)
Do something..
#set($a = $a+1)
label for=journal-$aType something/label
Do it like:
#foreach($mapping in $mappings)
Do something..
label for=journal- $velocityCount Type something /label
$velocityCount increase the value of variable incrementally, without having
to use ($a= $a+1)
I hope this helps!

In VelocityTools 2.0, you can just create a ToolManager and ask it for a ToolContext (which you can use like a standard VelocityContext) via the createContext() method.

Re: Best way to handle optional attributes in 1.6.2
Your original VTL amounted to #if ( null != ) when there was no
attribute value. The fact that this evaluated as false was a bug,
since null doesn't equal the empty string. Several little, obscure
comparison bugs like this were fixed prior to 1.6.2. I don't recall,
though, under which commit/JIRA Issue this fix was registered in the
changelog.

Re: Resource from a jar file
Yes, but at some point, many Velocity users will ship an app with finished templates that the customer won't modify. At that time, it can make a lot of sense to just keep your templates in the classpath or a non-classpath jar. Guessing from user examples and questions, the ClasspathResourceLoader is one of the more frequently used loaders. The JarResourceLoader is probably the least-used one. Personally, i use the WebappResourceLoader from VelocityTools most.

Re: Escaping EL in JSTL
In the upcoming 1.7, you'll be able to do
#[[c:if test=${ foo != null }]]#
but for now, you have to use what we call poor man's escaping:
#set( $D = '$' )
c:if test=$D{ foo != null}
Of course, it's best if you can just set the $D reference globally in
your context instead of every template. :)

Ok, it helps to know that you are using Struts 1 and VelocityTools.
This means it is likely that you are not creating/managing your own

So I have these two new lines added to the the VTL template - someMail.vm

#parse(header.vm)

#parse(footer.vm)
bother these header and footer reside in the same directory to which this
RESOURCE_PATH points, the engine is able to parse the mail template
correctly, but it is not able to parse gheader and footer and it fails with
ResourceNotFoundException . I am wondering why and how can I fix this
One obvious way is to add it to the mail template itself but I don't want to
do that because header footer will be referred by other pages on site as
well.
Why this ResourceNotFoundException exception is thrown though both files
reside in the same RESOURCE_PATH directory? How can I fix this?

just for variable $menuCurrentPage, randomly the message generates for any
variable and resolves on page refresh..??

Yes, it is a Velocity message. it means that in the template being
processed at that time, there is no value for th $menuCurrentPage
variable when it is being used in an #if( $menuCurrentPage ==
'something' ) comparison (or an #elseif).

Hi,
The problem I am facing is that occasionally Resourcenotfound/unable to
parse file error comes on the velocity pages which go on page refresh.
The following error is shown in the server logs before the logging of
resourcenotfound exception:
Left side ($menuCurrentPage) of '==' operation has null value. If a
reference, it may not be in the context. Operation not possible.
Is something related to the velocity engine here?
The problem is occurring right now only on staging site of my website,

and
is becoming troublesome

Without knowing a lot more about how you populate and use your context, i'm really not sure. Are you using a framework? If so, which one? Are you using VelocityTools at all? Are you sure your context is being handled in a threadsafe manner? Velocity looks for references in the context it is given. It's mostly up to you to make sure that context is properly filled and used.

Re: Facing Issues with velocity sortTool to sort Two java.util.Date Type
If there is an exception (like a NullPointerException) during sorting,
then SortTool will return null. The null field is apparently causing
an exception. I'm not sure why, but i would guess that it is because
the java.util.Date class' compareTo method doesn't like it when you
pass in null as an argument. SortTool never calls compareTo on a null
object, but it will pass null objects in to compareTo (e.g.
myNotNullComparable.compareTo(nullComparable) ).
That's the best guess i have for you. You might try subclassing
SortTool to right your own sort method that can handle this situation.
or just making your Note class comparable and doing
$sorter.sort(${notes}).

Hi,
I have a DTO Note.java in which there are some porperty like createdAt and

updatedAt and createdAt. When I create the note/entity on that time I set
java.util.Date() in createdAt property and not set in updatedAt so updatedAt
property is null in db and dto both at very first, when I am going to update
the same note/entity on that time I set the java.util.Date in updatedAt
property and update the entity then both property becomes not null, means
some values in dto and table. Now I want to sort the order of list by
updatedAt and createdAt so recent updated record should come on top and want
to shwo only recent five records only. If updatedAt and createdAt property
is not null then works fine. for example if there is 3 record and 2
note/entity are updated and one is not updated, means in list of 3 dto , 2
dto have values in updatedAt and in one DTO the value in updatedAt is null,
in this scenario not sorting and not displaying the records. I mean if any
of the updatedAt property is null in dto list then not display the record,.
I could not find the solution why this is not displaying while sorting?

happens? The code sample looks like you are already implementing the

What are you seeing happen? I'm sorry about the lousy feedback and variable responses. I know how difficult it is to problem solve with crappy data. I've got several webapps running together on a dev server, trying to juggle too many problems at one time. This is not the way to fix it. this is only log output for startup. can i see logs for what happens when you request a template, change it, then request it again? (or some similar set of actions that shows the problem) I need to setup a dedicated debug environment for this, turn on some logging, etc. and remove all the unnecessary variables, so I stop wasting your time. This may not even be a Tomcat problem. First, I checked my disk cache in Firefox for a test page: Last modified: 2009-04-22 11:20:14 Expires: 1969-12-31 16:00:00 As a simple test, I modified the test page, setting border=1 on a table, then saved it, and did a stat on the source file: Access: 2009-04-22 11:21:35.0 -0700 Modify: 2009-04-22 11:21:35.0 -0700 Change: 2009-04-22 11:21:35.0 -0700 So, the file is *newer* on server disk than the last modified cache date on the PC disk. I refresh the page, and the table border does not come on, meaning that the file was not read. If I check the Firefox cache, it shows: Last modified: 2009-04-22 11:21:50 Expires: 1969-12-31 16:00:00 So, I have to assume that something is caching this page within the server. But this is still all anecdotal. I'll setup a better test environment, with a standalone Tomcat instance and a single test page. The only thing I'm unsure of, is the level and type of logging. Is there something specific that can show cache info? I'd rather do a controlled experiment that can give you actionable data. In a simplified test environment, it should be manageable to have the log level set to debug. And using log4j should give the most control. The ServletLogger is a bit noisy. Also, if you are going to set up a test for this, as you describe, then once you have reproduced the problem and tried what we've discussed thus far, consider trying it again with Velocity 1.6.2 there have been a variety of fixes and improvements in the resource management code (and in logging, for more useful output).

Re: What does vm stand for?
As far as i know, it comes from the fact that Velocity was started as an Apache licensed alternative to WebMacro's templates which always had the suffix wm. I imagine, naming Velocity templates with the vm suffix made more sense then.

Re: Using Velocity only for scripting purposes
On Tue, Apr 7, 2009 at 11:17 AM, MS79 shapi...@gmail.com wrote: The application I'm working on currently uses Velocity for simple template processing; some forms, extract data, etc. In response to trying to meet a business need of a client, it was proposed that we use Velocity basically as an engine to allow users of the system to write custom logic in the system. This include statement logic and setting values on objects passed it (which would later be persisted to a database). No actual template processing would be done, it is essentially only used to set values on an object. ugh. While it would (and in fact, does) work, it just feels horribly wrong, especially when we have another engine hooked into the system to allow custom rule writing. Am I just being overly sensitive to the use of Velocity here, or are there any other downfalls that this implementation may have that we should be aware of. that would feel quite wrong to me too. Velocity is for templates, not scripting. Using VTL as a scripting language is like trying to pound in a nail with a screwdriver. It might work, but it ain't a good way to get the job done. Volume is supposed to be fairly low (at least as far as I've been told) and the templates would not be very complex. You say that now, but plans change. Shortcuts like this tend to hurt in the long run. You'll still use more memory than you need to, maybe more CPU too. And you'll definitely be working with a crippled scripting language, so your scripts are likely to end up ugly and hard to maintain despite your intentions.

If all above checks out, you might as well try $tn.getUSFormattedTn()

In any case, I revised the template to read as follows for experimental

In other words, yes, the object passed to the template was of the expected
class and no, I wasn't able to reproduce the problem.
If you still can't figure it out, write back confirming the above and
also let us know which version of Velocity you are using.
Hmm, could that be the issue? The production system where the problem
occurred is using 1.6.1. The development version (where I can't reproduce
the problem) uses 1.6.2. Since we will be using 1.6.2 in production soon,
if that is the case, it might solve the problem.
There were reflection related fixes between 1.6.1 and 1.6.2

Re: Inserting large text directly into the output
Pre-1.6 versions of Velocity always use toString() for references, without exception. So in a pre-1.6 situation, you pretty much have to create a custom directive to do something like this. With 1.6, though, we've introduced the Renderable interface: http://velocity.apache.org/engine/releases/velocity-1.6.2/apidocs/index.html If a reference implements this, then the render(Context,Writer) method is used. So, now you can go either way, and creating an object that uses Renderable to get at the writer is probably going to be easier than a custom directive.

I have some amount of text which won't necessarily fit in memory (to be more precise, it normally does, but there is a requirement that it not be truncated, no matter what.) Additionally, our framework for this works more efficiently if we can avoid using a Reader, and write directly to the destination Writer. So: 1. Is there some way that a template can call one of our methods, and our method can somehow get a reference to the Writer and write whatever it wants? 2. Failing that, is there some way to tell Velocity to insert the contents of a Reader directly into the output from the template, using a single template call? Or should I be taking some other approach to this, such as leaving a marker of some sort in the destination file, and then performing a second round of processing to get the text in there?

If I inject an object like a Map into the context, and from within VTL call add(Object o) on it, shouldn't this change be visible from outside the context, once execution of the template is done? Yes. The use case is tagging. Our application has several tier of content processing. - servlet - theme - N portlets - CMS content Only the servlet has access to write tags into the meta fields of the page, but N CMS contents and other objects have tags for inclusion. The issue is that for a couple reason we don't pass the real request object all the way through to the CMS processing. BUT, I want to enable CMS template developers to have the ability to submit tags programatically. So, I'd like to provide something like: #set ($VOID = $tags.add(...)) I'm confused; is $tags the HashMapString,String in question? If so, there's no add(String) method, only put(String,String). These would get collected post template into the actual request and at the servlet level verified and added to the meta information of the page. But, my initial tests aren't working, so either I'm doing something wrong (it's just a HashMapString, String that I'm using) or it's not possible. There's always crude debugging right there in the template. Make sure that $tags is present and of the expected type first, then be sure the method call worked. $tags.class $tags.get(...)

Re: Generic tools
Are you referring to Java generics? Or VelocityTools' GenericTools library? I'm guessing the the former, as that makes more sense of your question. Remember that Java uses generic types at compile time, then erases them: http://java.sun.com/docs/books/tutorial/java/generics/erasure.html Since Velocity runs off of runtime reflection, generic info isn't available. This means methods that take or return generic types work fine, but lack the compile-time type-checking. So, you will be able to call them with wrong generic types too, which may then lead to ClassCastExceptions. So, yeah, it'll work, but Velocity knows nothing of the generic types, so you should be as careful about types and casting as you would if those methods didn't use generics.

Re: Does velocity engine supports I18N ?
The ResourceTool is a generic tool. It is meant for offline use.
Just drop the generic jar in your app, and put an instance of the
ResourceTool in your context and it will look for and use a
resources.properties in the root of the classpath (unless you call a
method that specifies a different bundle). If you want to change the
default bundle, call setDefaultBundle. Pretty straightforward.
The MultiViewsTool currently has no support for offline use. In its
current incarnation, Servlet classes are required. If you'd like to
change that, patches are welcome. :) It's a tool whose original
contributor has gone away, so it doesn't get much attention.

Tiles2Tool is request scoped. Now, through the use of Tiles2Tool, a page is included. In the first page is created a ChainedContext (call it 1), in the included page a new ChainedContext is created (2). The problem is that Tiles2Tool is created and initialized when the request starts, and its velocity context is the one assigned in 1, since it is there that the Tiles2Tool is firstly used. But when used in the included page, it still refers to 1, though it should refer to 2. Ah, of course. I ought to have foreseen this. With Tools 1.x, there was once a complaint about the fact that the tools were being re-created for every include as well as the parent request. So in 2.x, i made a point to have request tools be truly request-scoped, failing to consider that some request tools should probably have stayed page scoped. Is there a way to solve this problem? Yes. :) But i don't know if it can be done internal to Tiles2Tool with the current API you have for it.

In Velocity 1.6, we introduced the org.apache.velocity.runtime.Renderable interface, which has a boolean execute(context, writer) method. If, when rendering a reference, Velocity comes across a Renderable, it calls that method instead of calling toString() and writing that value. but even if you do implement Renderable, please consider having your toString() be functional (e.g. passing a StringWriter and null context to execute(...)). I tried using the HttpServletResponse's writer, but it writes included resources in wrong order (as I suspected). It is the same effect that you would have in JSP tags when you use HttpServletResponse's writer instead of PageContext's one. yeah, we want content to run through Velocity, direct writing is frowned upon. I took a look at TilesTool and I noticed that, in fact, the included resources are transformed in strings and then returned to the template. Sincerely I don't like it. it keeps things orderly and flexible, allowing, for instance, tools to grab each other out of the context and interact with the same API. but yes, it can be a performance hit in situations involving a lot of content. In TilesViewServlet I noticed that, if bufferOutput is true, a StringWriter is used, otherwise the HttpServletResponse's one is used. I wish to use the correct writer in both cases. please do! but your options are restricted to Renderable (Velocity 1.6+) or toString() (any version). Velocity is not in the business of handing out the writer to objects before it is time to render them, sorry. Users can hack that in easily by extending VelocityView and overwriting performMerge(..) to drop the writer in the context, but that won't work well for a TilesTool.

Yes, if you need to programmatically manipulate the VelocityEngine properties, rather than set them via a velocity.properties file, this is still the way to go. You are sure you specified the org.apache.velocity.tools.view.class property in your init-params? Can you share your code and config, perhaps i can spot a mistake that is not obvious to you.

Re: [tools-2.0] How to create HTTP-request-based application-wide tool
Ok, i think i've got it now. Storing things in a ThreadLocal should allow an application scoped tool to have separate copies for each request, however, i don't see how you are going to automate setting those things into the ThreadLocal at each request. Perhaps you already have a plan for this, though? I can't think of a way to do that without requiring users to take an extra step such as use a custom VelocityView class or do something manual like $mytool.set($context.this) before using other functions. VelocityTools isn't in the business of setting request values into threadlocals for application-scoped tools, at least not yet. My inclination would be to avoid trying to keep this all in one class. Split your concerns. The simplest would probably be to put anything application scoped into a ServletContext attribute(s) and have a request-scoped tool pull that out when needed. For instance, you might have a MyToolAPI object that can live at the application level and a MyTool that is request-scoped. MyTool would look for the MyToolAPI in the servletContext attributes during configure(Map). If none is found, then it creates it and sets it in there for later ones to find. Then MyTool merely forwards a getFoo() request to myToolAPI.getFoo(request). This setup would keep creation of the request-scoped MyTool very cheap and limit any heavy lifting in MyToolAPI to once-per application. Does that make sense?

Or is it simply that you expect there to be a lot of instances of *the tool* created for every request and wish to share things between those instances. If that's it, then why not just store them as request attributes? I'm not sure i see why ThreadLocal is needed, though yeah, that should work too. I'm also not sure why you expect there to be a lot of instances of your tool created for every request. Have you seen this happening? The tool management code for Tools 2.0 stores the request-scoped tools in the request to allow them to be shared. The intention is that request scoped tools would only need to be created once per-request, even when request includes and forwards are involved. I'll admit i haven't tested that carefully though, so i'd like to know if i've misunderstood how RequestDispatcher handles request attributes for forwards and includes.

The answer is no; if you drop a new VelocityEngine into the VelocityView, then all configuration done on the previous engine is for naught.

Re: caching with multiple resource loaders
Sure, the default implementation class is: http://svn.apache.org/viewvc/velocity/engine/trunk/src/java/org/apache/velocity/runtime/resource/ResourceManagerImpl.java?revision=729843view=markup You can change that using this property: resource.manager.class = org.apache.velocity.runtime.resource.ResourceManagerImpl The ResourceManager sits atop the ResourceCache and the ResourceLoaders, coordinating their activity. I think the basic problem is that when multiple loaders are configured, the ResourceManager is not paying attention to which loader a cached resource came from. I imagine changing the refreshResource method to check if a cached resource that came from a lower-rung resource loader can be found in a higher one should do the trick. If you do get around to fixing this for yourself, would you consider sharing the fix?

Re: Problem with $actionURL in Spring Portlet
$actionURL is not something defined by Velocity. Velocity is just a
template engine, it doesn't know anything about action URL's unless
some other part of the application tells it about them. You should
ask about this on the Spring Portlet forum.

Yes, probably very difficult to find, possibly not worth the effort unless I catch it happening again. agreed. Using 1.6.1. Context is constructed from Properties objects (a Properties is-a Map) that my code passes around. Only right before it is passed to Velocity is the context constructed, using the VelocityContext(Map) constructor. in case you didn't already know, that constructor will use that Properties object as it's internal context store. it doesn't copy things over. so, if the whole lifecycle of your Properties object or VelocityContext is not completely contained within a single thread, then you have thread-safety issues. I have checked the pass-around path and I see no way that this properties object could have gotten corrupted between the time it was logged and the time velocity looked at it. It's a linear path between putting the object in the properties and passing the properties to my Velocity wrapper for conversion to a Context and passage to Velocity for merger with the template. There are no threading issues here - all this happens in one thread so I don't see a race condition. they're usually awfully hard to see, that's why i always suspect them when i can't see a problem that only rarely happens. once i (or my boss) decides such a bug needs squashing, i just start trying to replicate it. until i can make it happen at will, there's no way for me to know if i have really found and/or fixed it. anything and everything else is just speculation until the bug can be replicated.

Very true. I wasn't implying that for a default to Velocity, but as a solution to the potential memory issue in my scenario. You would just have to set the string.resource.loader.repository.class property or manually set the repo via: StringResourceLoader.setRepository(StringResourceLoader.REPOSITORY_NAME_DEFAULT, myStringResourceRepo); Regarding this, we already have: props.setProperty( org.apache.velocity.app.VelocityEngine.RESOURCE_MANAGER_CLASS, com.liferay.portal.velocity.LiferayResourceManager); props.setProperty( org.apache.velocity.app.VelocityEngine.RESOURCE_MANAGER_CACHE_CLASS, com.liferay.portal.velocity.LiferayResourceCache); Will the rendered Template objects fall into this cache anyway? If so, is there any reason to change the repository configuration? yeah, each String that you put into the repository, when requested, is parsed into a Template which will be managed/cached by the classes above. But that String will still be sitting in the repository too. If the repository is becoming a memory issue (as always, be wary of premature optimization), then it might behoove you to create your own StringResourceRepository that doesn't keep everything around.

Re: LinkTool and xHTML
Just call the setXHTML(boolean) method to change this behavior. or if you are configuring this in a tools.xml (Tools 2) or toolbox.xml (Tools 1), then you can set an xhtml property for the tool to true.
