[flexcoders] Re: Possible to invoke Flex2b2 compiler as a Java class?

Mon, 24 Apr 2006 08:33:08 -0700

Dave, thanks for your help! What you said makes sense, but
unfortunately I'm still having trouble with it.

Here's my ColdFusion code:

<cfscript>
      MXMLc = URLClassLoader.LoadJarClass("C:\Program Files\Adobe\Flex
Framework 2\lib\mxmlc.jar", "flex2.tools.Compiler");

      Args = '-flexlib "C:\Program Files\Adobe\Flex Framework
2\frameworks\" "C:\inetpub\builder\mxml\test1.mxml";

      MXMLc.main(JavaCast("String", Args));
</cfscript>

I *think* this follows what you suggested. When I try to run this, I
get the following error message:

"The selected method main was not found."

"Either there are no methods with the specified method name and
argument types, or the method main is overloaded with arguments types
that ColdFusion can't decipher reliably. If this is a Java object and
you verified that the method exists, you may need to use the javacast
function to reduce ambiguity."

So... any more tips?

BTW I do know that I'm initializing the class properly; if I pass
MXMLc to the CFDUMP tag, I see the following:

object of flex2.tools.Compiler
Methods:
      main (returns void)
      hashCode (returns int)
      getClass (returns java.lang.Class)
      wait (returns void)
      wait (returns void)
      wait (returns void)
      equals (returns boolean)
      notify (returns void)
      notifyAll (returns void)
      toString (returns java.lang.String)
FILE_SPECS:
      file-specs

Thanks!
Avi
