Im not sure if you can find a complete standalone example for this, but I think your problem now is with eval().<br><br>Can you copy your stackTrace here?<br><br>I think you can not do eval( literal == literal),<br>but you could make a function to test that if you wanna use eval and give the function the value of @{symbol}<br>

Hi Felipe,<div><br></div><div>thank you for your reply. I have now added the extra quotes but to no avail. I still get the same errors.</div><div><br></div><div>Is there somewhere a stand-alone example with the compile instructions to check that everything works? I have the impression that I'm having troubles with the whole eclipse config and plugin.</div>
<div><br></div><div>Thanks! Stefan</div><div><br></div><div><br></div><div><div class="gmail_quote">2010/4/26 Felipe Piccolini <span dir="ltr"><<a href="mailto:felipe.piccolini@gmail.com" target="_blank">felipe.piccolini@gmail.com</a>></span><div>

if you have a value in the example will be replaced as text in the rule and you will have something like this:<br>
<br>if @{symbol} == "THE_SYMBOL"<br><br>==><br><br><div>rule "A stand alone rule THE_SYMBOL"</div><div><span style="white-space: pre;"> </span>dialect "mvel"</div><div><span style="white-space: pre;"> </span>when</div>
<div><span style="white-space: pre;"> </span>eval(THE_SYMBOL == "AAA")</div><div><span style="white-space: pre;"> </span>then </div><div><span style="white-space: pre;"> </span>System.out.println("this symbol is" + THE_SYMBOL)<span style="white-space: pre;"> </span></div>
<div>end</div>----------<br><br>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<br>(")<br><br>your rule template should be something like this:<div>
<br>
<br><div>rule "A stand alone rule @{symbol}"</div><div><span style="white-space: pre;"> </span>dialect "mvel"</div><div><span style="white-space: pre;"> </span>when</div>
<div><span style="white-space: pre;"> </span>eval("@{symbol}" == "AAA")</div><div><span style="white-space: pre;"> </span>then </div><div><span style="white-space: pre;"> </span>System.out.println("this symbol is" +
"@{symbol}")<span style="white-space: pre;"> </span></div>

<div>Hi,</div><div><br></div><div>just starting using drools and need to use templates but having error messages (described in comments in the code below). </div><div>I checked the meaning of the error messages but still can't figure it out.</div>
<div>I modified an simple rule according to the template section of the drools manual: btw I use the eclipse with the drools-core plugin.</div><div><br></div><div>Thanks for your help. Stefan</div><div><br></div>
