Hi,
I am prototyping some code to include JRuby scripts in a Java app for
extensibility, and found that BSF/JRuby is not reporting compile errors. I
run a script (with a typo in "include_class") and all I get is this generic
exception:
Dec 20, 2006 9:39:17 AM scratch.test.TestJruby1 main
INFO: org.apache.bsf.BSFException: Exception
org.apache.bsf.BSFException: Exception
at org.jruby.javasupport.bsf.JRubyEngine.exec(JRubyEngine.java:113)
at org.apache.bsf.BSFManager$6.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at org.apache.bsf.BSFManager.exec(Unknown Source)
Here's the code to produce this (concat is a function that builds a string
with newlines between each element):
BSFManager.registerScriptingEngine("ruby",
"org.jruby.javasupport.bsf.JRubyEngine", new String[] { "rb" });
String script = concat(
new String[] {
"require 'java'",
"include class 'java.util.HashSet'", //
ERROR!!!
"begin ",
" set=HashSet.new",
" set.add 'foo'",
" set.add 'bar'",
" set.add 'fubar'",
" print set",
"rescue StandardError => err ",
" print \"Error:: \" + err ",
"end ",
});
BSFManager manager = new BSFManager();
manager.exec("ruby", "(java)", 1, 1, script);
shouldn't there be some indication of the compile error? Running directlly
in JRuby produces this (syntax) error:
$ java -jar lib/jruby.jar c:/tmp/fooBarTest.rb
:[-1,-1]:[0,0]: c:/tmp/fooBarTest.rb:1: syntax error, expecting '[' tDOT
tCOLON2 but found '\n' instead (SyntaxError)
