Got it. Thanks.<div><br></div><div>For future memory what I did was:</div><div><br></div><div><div>ros::ServiceServer service = n.advertiseService&lt;testpack::switcherRequest,testpack::switcherResponse&gt;(&quot;switcher&quot;,boost::bind(troca,_1,_2,500));</div>

</div><div><br></div><div><br></div><div><br></div><div><div class="gmail_quote">2010/10/25 Josh Faust <span dir="ltr">&lt;<a href="mailto:jfaust@willowgarage.com">jfaust@willowgarage.com</a>&gt;</span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

<div class="gmail_quote"><div class="im"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><br></div><div>And it doesn&#39;t work.</div></blockquote><div><br></div>

</div><div>First, saying &quot;it doesn&#39;t work&quot; is meaningless.  Please include the exact errors you&#39;re getting in the future.</div>

<div><br></div><div>Second, if you look at the API docs, advertiseService needs both the request and response types (and std_msgs/String is not a service type).</div><div><br></div><font color="#888888"><div>Josh</div></font></div>
