Application Resources and TextTool
Hi all,
I get this weird bug(?) with TextTool.
On my struts-config.xml I declare the following message resource
message-resources parameter=DestinationsResources key=destinations /
then in my template I use the textool to retrieve a value from that resource
$text.get('title.img', 'destinations')
and I get a ClassCastException with the following stack trace,
java.lang.ClassCastException
at org.apache.velocity.tools.struts.StrutsUtils.getMessageResources(Unknown
Source)
at org.apache.velocity.tools.struts.MessageResourcesTool.getResources(Unknown
Source)
at org.apache.velocity.tools.struts.MessageTool.get(Unknown Source)
at org.apache.velocity.tools.struts.MessageTool.get(Unknown Source)
changed the key of the message resource to destination (notice the 's'
missing)
using the new key value... and it works :/
thats using velocity-tools-1.1
I also have other resources that use the same notation,
message-resources parameter=IndexResources key=index /
and cause me no problems.
Thanks in advance,
Markos Charatzas

Charset (Struts and Velocity)
Hi there, Although, 1. I have defined the charset in struts-config.xml like the following controller contentType=text/html; charset=ISO-8859-7/ 2. In velocity properties I have set both input.encoding=ISO-8859-7 output.encoding=ISO-8859-7 3. my html templates have the content type set properly 4. my resource files are in the corrent content type I still get question marks (?) displayed back to the browser when displaying anything that comes from an ApplicationResource file :( Thanks in advance.

VelocityViewServlet Differences with VelocityServlet
I've taken the advice offered by everyone to switch to using the VelocityViewServlet but I've got a strange error occurring which didn't happen with VelocityServlet (or if it did, it was caught). When I log out from my application I clear the session object by doing a session().invalidate() Now, when the template for the logout screen is merged by Velocity. I get the following error; java.lang.IllegalStateException: getAttribute: Session already invalidated I can't understand this, I don't refer to the session object in my template so why is the VelocityViewServlet checking the session object? Also, why doesn't it catch this error gracefully? Steve - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: VelocityViewServlet Differences with VelocityServlet
hmm. i've not had problems with invalidated sessions before. can you give us some of that stack trace? i wanna see where this is happening.

Re: Application Resources and TextTool
the relevant code (in veltools 1.1's StrutsUtils) is doing the following:
resources = (MessageResources) request.getAttribute(bundle +
moduleConfig.getPrefix());
if (resources == null) {
resources = (MessageResources) app.getAttribute(bundle +
moduleConfig.getPrefix());
}
this seems to indicate that there is something in either your request
attributes or servlet context attributes under the key destinationsX
(where X is your module config prefix) that is not a MessageResources
object. i'm not sure how this would happen, but it is. for tracking
the problem down, you might first try retrieving that object yourself
and finding out what it is. you might also grep your app to find any
other place that an object would end up in your request or servlet
context attributes with that same key, because something is probably
doing so and thus replacing the MessageResources object that should be
there.

Re: velocity and JET (java emitter templates)
Hi Mike, Hi Does anyone have any any experience working with both of these template technologies? I'm evaluating both and trying to get a feel for what they can and can't do, so far I'm getting the impression that velocity provides a more flexible solution but wondering whats your experiences out there might have been with both. Sorry, I don't know anything about JET, but I was wondering if you could share with us what you have found about the two. Maybe we can add a new page under Comparisons. :) Best regards, -- Shinobu -- Shinobu Kawai Yoshida [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Charset (Struts and Velocity)
Hi Markos, Although, 1. I have defined the charset in struts-config.xml like the following controller contentType=text/html; charset=ISO-8859-7/ 2. In velocity properties I have set both input.encoding=ISO-8859-7 output.encoding=ISO-8859-7 #* Actually, the output.encoding doesn't matter unless you're using VelocityServlet or Anakia. ;) http://jakarta.apache.org/velocity/developer-guide.html#Velocity%20Configuration%20Keys%20and%20Values *# 3. my html templates have the content type set properly 4. my resource files are in the corrent content type Please refresh my memory. Was there a way to specify content type in resource files? I thought they were just PropertyResourceBundle files. I still get question marks (?) displayed back to the browser when displaying anything that comes from an ApplicationResource file :( Question marks usually means that the charset converter couldn't find the suitable character for the conversion. If you spit out some log from java, is it encoded properly, or do you get question marks there, too?

Re: velocity and JET (java emitter templates)
Sorry, I don't know anything about JET, but I was wondering if you could share with us what you have found about the two. Shinobu Kawai Yoshida [EMAIL PROTECTED] Sure thing, What I have found is that JET or Java Emitter Templates is an Eclipse technology www.eclipse.org and part of EMF (though I'm sure it could have been made a separate plugin). Similar to Velocity, JET takes templates, script and data objects and merges the three to create a final output. JET uses a JSP like scripting language. JET also allows full translation from templates to resulting output or you can compile your templates to java classes, and simply invoke the java class. If your interested in this I have found two really good tutorials on the technology which can be found at: http://www.eclipse.org/articles/Article-JET/jet_tutorial1.html and http://www.eclipse.org/articles/Article-JET2/jet_tutorial2.html I haven't really come to any conclusions other than JET is built into eclipse and supports eclipse projects. The few tests I have ran with JET have been very favorable, I didn't run into any problems with what I Was trying to do. Performance wise I have no ideas how the two compare, though the compile to class feature might be nice. ALSO I thought I'd mention that while I was researching JET I ran into another new technology that is for reporting that is being worked on called BIRT (B.I.R.T.). Business Intelligence and Reporting Tools, take a look at http://www.eclipse.org/birt/ Though thats about the extent of my knowledge at this point on it.
