ClassCastException on parsed file

I am trying to 'parse' a template file to no avail.
The error spit out by Velocity is:

Tue May 14 14:26:46 CDT 2002  [error] #parse() : arg =
header.inc.html.  Exception :
java.lang.ClassCastException:
org.apache.velocity.runtime.resource.ContentResource

Any one have any ideas?

[reprise] velocimacro.context.localscope crashes

Posted by ro...@yahoo.com.

hi geir,

did you find anything about this velocimacro-crash?

here once again the possibly shortest jython script
that creates this error

>>> from java.util import Properties
>>> from java.lang import Boolean
>>> from org.apache.velocity.app import Velocity
>>>
>>> props = Properties()
>>> props.put("velocimacro.context.localscope", Boolean.TRUE)
>>>
>>> Velocity.init(props)

hi,

a string containing a list of macro-files to be included.
but this is not the reason of this error. only excluding the line

   props.put("velocimacro.context.localscope", Boolean.TRUE);

helps.

'getMacros()' return?

velocimacro.context.localscope crashes

hi,

am trying to set "local" vars in velocity
but when doing so by setting the properties
of the context-object. velocity crashes.
any ideas.

heres the resulting trace

and thats the java-soruce:

    {
        Properties props = new Properties();
        props.put("file.resource.loader.path",

        props.put("velocimacro.library", getMacros());
        props.put("velocimacro.context.localscope", Boolean.TRUE);
        //LOGGER.log(Level.INFO, getMacros());
        return props;
    }

...
      Properties props = getProperties();
      Velocity.init(props);
...
