How do I use URIs with parameters in XML?

If you try and use one of the Camel URIs in an Xml Configuration using the URI query parameter notation, such as

Code Block
langxml
<route>
 <from uri="direct:start?paramA=1&paramB=2"/>
 <to uri="mock:result"/>
</route>

you might get errors such as...

Code Block
Caused by: org.xml.sax.SAXParseException: The reference to entity
"paramB" must end with the ';' delimiter.
  at
com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:236)
  at

This is because in XML you need to escape some special XML characters like these

&amp;
Code Block
<
Code Block
&lt;
Code Block
>
Code Block
&gt;

So if you write the following XML it should work...

Code Block
langxml
<route>
 <from uri="direct:start?paramA=1&amp;paramB=2"/>
 <to uri="mock:result"/>
</route>
