All
I have to that upgrading a 3.0.x JBoss rules project to a 4.0.x version is
not the smoothest transition.
First, I reported that the library path is not correct but I was able to
work around this issue.
Now, I found another feature/bug. When I click on RETE view, I get the
following exception:
!ENTRY org.drools.eclipse 4 120 2007-07-08 17:54:09.181 !MESSAGE Internal

Do I really have to create a new Project and re-import everything over to it
to get it to work properly? Is there no upgrade feature that automatically
upgrades my project like in most other Eclipse plugins?
Thanks!
Ron

The 'in' operator is just sugar for == 'stilton' || == 'brie' but we
felt it improved the declarative nature of the language sufficiently to
warrant the sugar.

All,
OK, a new project cleared up the RETE view. I will say the problem still
does exist where the project does not work properly unless I import the JDT
compiler.

Content-Type: text/plain; charset="us-ascii"
Hi,
Has anyone used the "matches" operator?
In our application we need to support startWith, endsWith operators for
string variable. I am thinking of using matches operator. But the 'matches'
operator is not working. I am trying the following code
rule "Hello World"
when
m : Message(message matches "Hello*")
then
System.out.println( "Hello World");
end
And the value set in the message is "Hello World". But it is not going into
the then clause.
If anyone has already used matches operator I would like to know how we can
use it for startswith, endsWith. How do we specify the regular expression?
Can we use "*"
Thanks,
Ashwini
