Hi All,

	Ok, unfortunately after playing with the jar files and CLASSPATH
	setting the problem from my previous mail was still apparent.

	So, after spending an hour wondering through the C2 source, I found the
	cause of the problem and fixed it - here goes:

	From what I understand, the call to sun.tools.javac.Main (in
	Javac.java) is built up dynamically with stored values (which includes
	the classpath) by the method fillArguments (AbstractJavaCompiler.java).
	
	The classpath used to be obtained via a call to System.getProperty()
	(in JavaLanguage.java), with the parameters "java.class.path". This
	was changed recently to an attribute lookup specific to Tomcat (in
	CocoonServlet.java), namely org.apache.catalina.jsp_classpath (I
	presume this must be a Tomcat 4.0 attribute, as I currently use Tomcat
	3.2beta4).

	This explains why changing the classpath didn't fix the problem - it
	was ignored in the compiler call.

	The comment indicates that Javac (.java) must be redesigned for a long
	term solution. Short term - I changed line 78 in CocoonServlet.java
	from

	this.classpath = (String) context.getAttribute(SERVLET_CLASSPATH);

	to

	this.classpath = System.getProperty("java.class.path");

	and the problem I had before went away.

	OK, now that I can use Cocoon2, can someone please explain to me in a
	bit more detail what the issues were with Javac (.java) ? And what
	would need to be done to it for a long term solution ?

	Cheers, thanks for your help. :-)

	Marcus
