Hi Mike, I&#39;ve never tried that before (a rule without the when part..) is good to know that it works :)<div>Humm that&#39;s sounds weird.. why the dialect is affecting your Client creation.</div><div>It could be that there is something wrong with the expression evaluation.</div>

<div>It looks like MVEL cannot compile the new Client(); expression -&gt; at java.lang.String.&lt;init&gt;(Unknown Source)</div><div>Did you try with something like:</div><div>then \n</div><div>Client c = new Client();</div>

<div><br></div><div>I&#39;m just guessing here, because it looks strange<br><br><div class="gmail_quote">2012/3/14 mike <span dir="ltr">&lt;<a href="mailto:mikemps@gmail.com">mikemps@gmail.com</a>&gt;</span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Hi Mauricio,<div><br></div><div>Thank you for the speedy reply. Ia m making rest call to web services using jersey. I simplified the rule to the max. The &#39;when&#39; is not really needed. I get the exception on the call to &quot;new Client()&quot;. Please keep in mind it works without dialect &quot;mvel&quot;.</div>

Hi there,<div><br></div><div>I am trying to make rest calls from Drools. For that I am using Jersey <a href="http://jersey.java.net/" target="_blank">http://jersey.java.net/</a>. I cannot no get it to work if I use mvel, otherwise it works fine. </div>





<div><br></div><div>Here is a sample rule:</div><div>----------------------------------------------------------</div><div><div>import com.sun.jersey.api.client.Client;</div><div><br></div><div>dialect  &quot;mvel&quot;</div>





<div><br></div><div>rule &quot;create Rest Client&quot;</div><div>    then new Client();</div><div>end</div></div><div>----------------------------------------------------------</div><div><br></div><div>I would love to be able to use mvel since it curves java syntax :) <br>





</div><div><br></div><div>Thank you<span><font color="#888888"><br></font></span></div><span><font color="#888888"><div>Mike</div>
