Parsing URI's with multiple parameters w/ Spring
Using the latest from camel's trunk, I modified camel-spring's
simpleRoute.xml so the route looks like this:
<route>
<from uri="direct:start?paramA=1¶mB=2"/>
<to uri="mock:result"/>
</route>
Running "mvn -Dtest=SimpleRouteTest test" then gives me the following
stacktrace:
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:
Line 28 in XML document from class path resource
[org/apache/camel/spring/example/simpleRoute.xml] is invalid; nested
exception is org.xml.sax.SAXParseException: The reference to entity
"paramB" must end with the ';' delimiter.
Caused by: org.xml.sax.SAXParseException: The reference to entity

This seems to happen for any uri that has multiple parameters in its
query string (eg:
"ftp://camel-user@localhost:123/tmp?password=secret&binary=true" which
parses fine in camel-core's UriConfigurationTest.) My XML kung-fu is
weak, so I'm not quite sure where to begin.
Maybe a red herring, but I see the following messages during the
[antrun:run {execution: process-sources}] step:
/Users/acricken/workspaces/apache/camel/components/camel-spring/target/schema-src/org/apache/camel/spring/CamelBeanPostProcessor.java:37:
package org.apache.camel.spring.util does not exist
import org.apache.camel.spring.util.ReflectionUtils;
^
/Users/acricken/workspaces/apache/camel/components/camel-spring/target/schema-src/org/apache/camel/spring/CamelBeanPostProcessor.java:62:
cannot find symbol
symbol : class SpringCamelContext
location: class org.apache.camel.spring.CamelBeanPostProcessor
private SpringCamelContext camelContext;
(and then a bunch more cannot find symbol : class SpringCamelContext)
Any ideas?

So when XML encoding URIs, you need to use & instead of &. So this
should do the trick...
<from uri="direct:start?paramA=1&paramB=2"/>
Sometimes XML is a total pain in the ass - I mean who uses entity
references any more.
BTW I've added a FAQ entry on this as I see other folks hitting this XML pain...

Oh thats just a warning (I wish I could figure out how to hide) when
running the XSD generation step - you can safely ignore those.
Basically I don't think the classpath is exactly right so that the
JAXB2 code generation of the XSD does have warnings.
