Re: [rules-users] template 101

Using template you will see that the @{} is replaced "just as is" from the data (for example from a spreadsheet), so if you have a value in the example will be replaced as text in the rule and you will have something like this: if @{symbol} == "THE_SYMBOL" ==> rule "A stand alone rule THE_SYMBOL" dialect "mvel" when eval(THE_SYMBOL == "AAA") then System.out.println("this symbol is" + THE_SYMBOL) end ---------- So as you can see, the variable is no more a variable in the generated rule, just text, so if you wanna use it as a string, you should add double-quote (") your rule template should be something like this: rule "A stand alone rule @{symbol}" dialect "mvel" when eval("@{symbol}" == "AAA") then System.out.println("this symbol is" + "@{symbol}") end 2010/4/22 Stefan Marconi <stefan.marconi(a)gmail.com&gt; > Hi, > > just starting using drools and need to use templates but having error > messages (described in comments in the code below). > I checked the meaning of the error messages but still can't figure it out. > I modified an simple rule according to the template section of the drools > manual: btw I use the eclipse with the drools-core plugin. > > Thanks for your help.
