title: calling a new class on filter tag apache camel
body: <p>I have this code on my router class</p>
  
  <pre><code>from("seda:singleInvoicesChannel")
                  .filter(new LowEnoughAmountPredicate())
                  .to("seda:filteredInvoicesChannel");
  </code></pre>
  
  <p>now iam trying to transfer it on my camel-context.xml with this</p>
  
  <pre><code>&lt;route id="singleInvoicesChannel"&gt;
            &lt;from uri="seda:singleInvoicesChannel"/&gt;
            &lt;filter&gt;
  
            &lt;/filter&gt;
            &lt;to uri="seda:filteredInvoicesChannel"/&gt;
        &lt;/route&gt;
  </code></pre>
  
  <p>my question is what will i put inside the filter tag to fulfill the .filter(new LowEnoughAmountPredicate());.</p>
