$toolLoader problem (Was HTML escape sequence filtering (is there a tool for that?))

[Ed Yu <ek...@asgnet.psc.sc.edu>]

Thanks. Here is my findings:

Using the toolbox.xml to define the tool works, but using the
$toolLoader tool does not:

  <tool>
    <key>xmlTool</key>
    <class>org.apache.velocity.anakia.Escape</class>
  </tool>

Here is the code:

#set($beginTag = "<font color='blue'>")
#set($endTag = "</font>")

$beginTag
See blue?	## This produces color blue
$endTag

<hr>
$xmlTool.getText($beginTag)
See blue with escape?	## This does not produce blue, so far so good!
$xmlTool.getText($endTag)
<hr>

$toolLoader("xmltool","org.apache.velocity.anakia.Escape") ## This seems
to work
$xmltool.getText($beginTag) ## This does not work
See blue with escape?
$xmltool.getText($endTag) ## This does not work

## The above code outputs
org.apache.velocity.tools.tools.ToolLoader@6d2702("xmltool","org.apache.
velocity.anakia.Escape") $xmltool.getText($beginTag) See blue with
escape? $xmltool.getText($endTag)

## In the log file
2002-07-15 10:36:05 - /VelocityStrutsTest:  Velocity   [warn]
org.apache.velocity.runtime.exception.ReferenceException: reference :
template = /t.vm [line 33,column 1] : $xmltool.getText($beginTag) is not
a valid reference.

Being fundamentally lazy, I just tend to do this :


 vc.put("xmltool", new org.apache.velocity.anakia.Escape());

try  #set( $xmltool =
$toolLoader.load("org.apache.velocity.anakia.Escape") )
