Hi all,
I'm just in the process of moving over to the velocity world (from JSP tags
world), so please excuse if I'm doing something obviously wrong.
Basically, I'm trying to display form errors in relevant parts of the interface
using the following code snippet:
#if
Hi,
Please excuse this thread. I had another application.properties file lurking
in my classpath that was being read rather than the one that I was updating.
So, it looks as if Velocity will output the properties key if it can't find a
value for the key.
Cheers

You can also use plain VTL:
#set( $id = $number )
#set( $len = $id.length() - 4 )
$id.substring($len)
To simplify the use, you can create a macro for this:
#macro( fourdigits $number )#*
*##* #local( $id $len ) *##*-- optional directive, avoids polluting
context
*##set( $id =

Is there a binary for ArrayTool somewhere or do I just build it?
And how would it get configured programmatically (eg.
velocity.setProperty())?

That didn't work for me. Is there a setting to allow it?

Hi,
I also used Array Tool before. However, looking at the source of it,
it appears to me that every time you call a method of the Array tool,
it creates a new instance of the array list internally, which is mild
performance problem.
So, now I tried to avoid using it. What I did is to use
Hi all,
Has anyone implemented a JDBCRealm and MD5 encrypted passwords with a
velocity app? I've got everything working, with one exception. I've got
some admin pages that need a way to encrypt clear text passwords from
an HTML form before storing them in the database.
I've Googled this and
You can't do this in Velocity. Check out the java.security classes.
I'm doing MD4:
import gnu.crypto.jce.GnuCrypto;
import java.security.MessageDigest;
import java.security.Security;
public static byte[] encryptMD4(String s) throws Exception {
Security.addProvider(new GnuCrypto());

Yeah, that's exactly how I felt. It just took me a lot longer to figure it
out.
Wonderfully brilliant yet simple idea once you realize that there's nothing
special about a tool. :)
And its nice to use something that makes me say ahh instead of
