reports, success stories and/or patches required to get this code
to run on other engines would be appreciated.
2) This code clean compiles on Win32 and Linux, and is able to process
phpinfo() commands. Most of the code is in place, but very little
testing has been done on even such basic things as cookies and
sessions. Treat this code as early alpha at this point.
3) Until overload resolution is addressed in php/java, much of the
javax.servlet interfaces can not be directly called. For example,
don't try to get the output stream from $response, and expect to
be able to use println. For now, use PHP's "echo" instead.
4) PHP has a habit of changing the working directory. Sapi/servlet will
2) PHP has a habit of changing the working directory. Sapi/servlet will
eventually change it back, but while PHP is running the servlet engine
may not be able to load any classes from the CLASSPATH which are
specified using a relative directory syntax, or find the work directory
