Hi Markus,
You've almost got things right. The ParameterParser is used for
parsing the parameters of the current ServletRequest. This means you
must have it as a request-scoped tool. When you try to put it as an
application-scoped tool, then the wrong thing is sent to the init()
method and the tool complains.
Also, $params.getString is not the proper way to use the tool. You
need to specify which request parameter you wish to get:
$params.getString('foo')
You can also simplify that by just doing $params.foo if you don't
need to parse the parameter and just want it as a string.

Hi guys,
I downloaded the tools and tried the example provided with the package
(simple - servlet). It works fine. Now I want to get the parameter out of
the url to work with it in velocity. I think the right tool for it is the
ParameterParser (if not please tell me how to get the parameters out of the
url).
So I did the following:
I added this to my toolbox.xml:
<tool>
<key>params</key>
<scope>application</scope>
<class>org.apache.velocity.tools.view.tools.ParameterParser</class>
</tool>
And this to my template:
Parameter tool: $params.getString
But when starting up tomcat I get various failures (the date tool for
example is working properly):
[...]
Problem loading toolbox '/WEB-INF/toolbox.xml':
java.lang.IllegalArgumentException: Was expecting interface
org.apache.velocity.tools.view.context.ViewContext or interface
javax.servlet.ServletRequest
[...]
Do I have to download this tool to use it or should it be provided with the
tools-1.2 anyway?
Thanks in advance,
markus
