The PHP/Java Bridge code is correct. The decorator you've set connects
the writer, reader, errorWriter to the servlet. So your code has no
effect.

Please see the example code I've given.

BTW: For PHP/Java Bridge 6.2.1 I will rename the decorator to
"PhpHttpScriptContext". Please either use your own decorator (copy
PhpHttpCompiledScriptContext.java to your project) or please use the
new name.

The test script I've used is below:
