RE: [rules-users] pattern
by DELBART Vincent
Hi,
I think you have to use "Test\\s+".
I don't think it's a DROOLS problem (maybe jdk).

Objet : [rules-users] pattern
Drools Documentation says:
Matches a field against any valid Java Regular Expression. Typically that regexp is a String, but variables that resolve to a valid regexp are also allowed. It is important to note that different from java, if you write a String regexp directly on the source file, you don't need to escape '\'. Example:
but
"Test\s+" is a valid RegEx (it was valid in Drools 3.x too), but now:
SyntaxfehlerRule Compilation error : [Rule name=OnlineStreaming Start, agendaGroup=MAIN, salience=100, no-loop=true] com/p7s1/swi/phoenix/n24/Rule_OnlineStreaming_Start_0.java (19:923) :
Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \\ )
What i'm doing wrong here?
Cheers

RuleNameEqualsAgendaFilter
by Manukyan, Sergey
Folks,
The RuleNameEqualsAgendaFilter doesn't fire rules when used with Rule
Flow.
Without is all rules fire fine, but I need to limit it to only one.
Is that a know issue? Or maybe I cannot use it together with Rule
Flows....?

RE: [rules-users] Basic questions about rule deployment
by Hehl, Thomas
Just a note about URLs. URLs will automatically do base 64 encoding, which
primarily means that all spaces are replaced with %20%. If you are using a
URL to represent a file, make sure you test it with a file that has spaces
somewhere in the path.
I just learned this the hard way. You may need to convert your URL to a URI.
Good luck!

Subject: Re: [rules-users] Basic questions about rule deployment
Thank you very much!
I followed your advice and created URLs for my .drl and .dsl files.
Then I created a new URLClassLoader instance with these two URLs.
Finally I assigned this class loader to my packager builder using:
myPackageBuilder.getPackageBuilderConfiguration().setClassLoader(myURLClassL
oader);
Absolute path names seem to be Ok, as long as one uses "file:" as a prefix
to the URL string. I plan to use a config file to specify the locations of
my rule files (dsl and drl). The location of the config file itself will
then be defined by a command line argument.
Thanks again!
