URL Encoding a Camel Exchange Body - activemq

Question

I need help with this question.
I'm using the camel-http component as shown here but I'm having trouble because the body I'm sending has unescaped ampersands. This is causing the query string on the receiving server to break the post into multiple post parameters.
I know I could create compiled routes in java, but I must use the spring xml dialect so that new routes may be create/changed in the config files without a recompile.
So, in short, I'd like to URL Encode the ${body} property on my route using the spring dialect as shown in the (obviously invalid) pseudocode below.
<setBody inheritErrorHandler="true" id="setBody2">
<simple>name=<urlencode>${body}</urlencode></simple>
</setBody>

Ok, I bit the bullet. I created a java POJO
package com.wufoo.camel;
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import org.apache.log4j.Logger;
public class PayloadEncoder {
public String getEncodedBody(String body) throws UnsupportedEncodingException {
Logger mylogger = Logger.getLogger("log4j.logger.org.apache.camel");
mylogger.info("Appending payload and URL Encoding");
String encodedBody = new StringBuffer()
.append("payload=")
.append(URLEncoder.encode(body, "UTF-8")).toString();
return encodedBody;
}
}
Then injected it into the context
<bean id="payloadEncoder" class="com.wufoo.camel.PayloadEncoder" />
And finally used a transform to encode the body
<transform>
<method bean="payloadEncoder" method="getEncodedBody"/>
</transform>
That works. If anyone can tell me what's wrong with this approach, please let me know.

You can also use groovy language, like this:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint
xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.osgi.org/xmlns/blueprint/v1.0.0
http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route>
<from uri="file:camel/input"/>
<log message="Moving ${file:name} to the output directory"/>
<setBody>
<groovy>
"name=" + URLEncoder.encode(request.getBody(String.class));
</groovy>
</setBody>
<to uri="file:camel/output"/>
</route>
</camelContext>
</blueprint>
