ParseException when using PigServer.registerScript against a file that has a %declare directive

Hi,

We are trying to test a pig script using JUnit and the PigServer. This pig
script uses parameters. It works great running it through the pig command
line, but the registerScript function blows with a ParseException on both
the %declare and %default directives.

org.apache.pig.tools.pigscript.parser.ParseException: Encountered " <PATH>
"%declare "" at line 2, column 1.
Was expecting one of:
    <EOF>
    "cat" ...
    "cd" ...
    "cp" ...
...


Am I doing something wrong?

Thanks,
Christian

Yes, parameter substitution is implemented as a preprocessor that
rewrites the script before passing it to PigServer.

Hi Christian,
Parameter substitution is currently supported only for the command line mode
(batch mode). 
A preprocessor processes the entire pig-script at once to do parameter
substitution. This preprocessor does not get invoked when you call PigServer
directly or if the interactive mode (grunt shell) is used.
