Hey guys,
I read in a previous post that == in Drools 4.0.7 maps to .equals()
automatically. My situation required me to put a String object into the
working memory and do a comparison on it to see if a particular word is in
the passed String sentence. Could anybody please guide me as to how to
approach this problem? Thanks in advance. Here's my original code:
rule "Find Alpha in a sentence"
*
salience* 100
wrap: WrapperClass(Sentence == "Alpha")
then
System.out.*println*("Aha found ya!");
end
10:35 p.m.
If the string you are looking for is a substring of your sentence, you
need to either use a regexp or an eval to call for an indexOf-like method:
WrapperClass( sentence matches ".*Alpha.*" )

Thanks for your reply Edson. What if I want to test for multiple substrings
in different strings?
For example, how can I find beta in sentence2?
I tried to combine WrapperClass( sentence matches ".*Alpha.*" &&
sentence2
matches ".*Beta*.") but I got errors.
Thanks,
Armaghan

Try like this..it's working fine.
$c :CashMemoDtl(articleCode:articleCode)
eval($c.getArticleCode().equals( "Laptop") &&
$c.getArticleCode().equals(
"Mouse") )
Thanks,

It works, but it is not idea, because drools cannot index the constraints
used inside an eval. If you are testing for equals, better to use regular
constraints.
