Rules and navigation

[statelessbean]

Hi all,
I'm newbie in seam...
I want to use drools and rules in my seam pages but i dont understand how and where are used those roles.

can anyone give me link or post me litle example how to use those drools?
On doc files i found somethink like this:

<page view-id="/editDocument.xhtml">

 <navigation from-action="#{documentEditor.update}">
 <rule if="#{documentEditor.errors.empty}">
 <end-conversation/>
 <render view-id="/viewDocument.xhtml"/>
 <rule/>
 </navigation-case>

</navigation-rule>

if my undestanding is well here we use rule, but what how? and where is "name" of those rule?

I understand little bit rules but i still have problems with implementation in code and don't know where are they used (in source code) and in with cases.

I would suggest go ahead and open the source code. Look into the resources folder and you will see a file called numberguess.drl . Examine that and then look at the source code.

Contents are

package org.jboss.seam.example.numberguess

import org.jboss.seam.drools.Decision

global Decision decision

rule High
when
RandomNumber(randomValue:value)
Guess(guess: value>randomValue)
game: GameHistory()
then
game.setBiggest(guess.intValue()-1);
end

rule Low
when
RandomNumber(randomValue:value)
Guess(guess: value<randomValue)
game: GameHistory()
then
game.setSmallest(guess.intValue()+1);
end

rule Win
when
RandomNumber(randomValue:value)
Guess(value==randomValue)
then
decision.setOutcome("win");
end

rule Lose
when
GameHistory(guessCount==9)
then
if ( decision.getOutcome()==null )
{
decision.setOutcome("lose");
}
end

rule Incremement
salience -10
when
game: GameHistory()
then
game.incrementGuessCount();
end





Also look at the file next to it called pageflow.jpdl.xml . I'm not putting contents for that here though :)

Then feel free to ask specific questionsa bout functionality of seam+drools int hat application. once you have that implementation down, you'ld be ok to start your own seam+drools project

oh Mr. Bean i forgot to say the above stuff was the seam(distribution)/examples/drools/ . I learned the functionality from that example, which is pretty good. Personally i'm not using drools for now. Dont want to get tangled into alot of new stuff.
