Camel Spring XML
Hi,
I am a newbie using Apache Camel.
I am trying to configure 2 different routes based on the servlet example in
the package.
My route configuration looks as below:
<camel:route id="route1">
<camel:from uri="servlet:///hello"/>
<camel:choice>
<camel:when>
<camel:header>name</camel:header>
<camel:transform>
<camel:simple>Hello ${header.name} world</camel:simple>
</camel:transform>
</camel:when>
<camel:otherwise>
<camel:to
uri="http://localhost:8080?&bridgeEndpoint=true&throwExceptionOnFailure=false"/>
</camel:otherwise>
</camel:choice>
</camel:route>
<camel:route id="route2">
<camel:from uri="servlet:///helloWorld"/>
<camel:choice>
<camel:when>
<camel:header>name</camel:header>
<camel:transform>
<camel:simple>Hello ${header.name} world</camel:simple>
</camel:transform>
</camel:when>
<camel:otherwise>
<camel:to
uri="http://10.74.81.81:8080?bridgeEndpoint=true&throwExceptionOnFailure=false"/>
</camel:otherwise>
</camel:choice>
</camel:route>
I wish to pass parameters and somewhere for to:uri servlet path which I read
from somewhere can be done as
servletName[?requestParameter1=parameterValue1&requestParameter2=....]
When tried using above, I get xml parsing exception while loading the
application.
Can please suggest how to pass parameters at runtime?
Thanks in advance,
Manoj Kolhe

Why dont you try sending a HTTP POST to the Camel servlet and see what happens.

Now the next question on my mind,
This is plain example for fetching request parameters as GET method.
How to pass the parameters to as POST?

is evaluated as if there is a header with the key name or not, and if
there is a header, then its value is != null.

If you run this example
http://camel.apache.org/servlet-tomcat-example.html
It outputs in the webpage how to provide a name, eg by adding ?name=Claus
to the http url in your web browser.

Hi Claus,
Thanks, I referred to the example stated on the link you have provided.
Apologies to ask you a very basic question in this case:
<choice>
<when>
<header>name</header>
<transform>
<simple>Hello ${header.name} how are you?</simple>
</transform>
</when>
In above 'choice when' code, how to associate header with key name?
As I executed the code provided on the link and it is always executing the
'choice-otherwise' segment.
Thanks in advance,
Manoj

You cannot set hardcoded http request paramters on the servlet component.
Its the HTTP client that can send request parameters when it calls the
HTTP service
See this example
http://camel.apache.org/servlet-tomcat-example.html

Hi Claus,
Thanks for quick revert.
I resolved the issue of passing parameters in <camel:to uri="http...">
Current Issue:
Now the main thing to me is how to receive parameters from <camel:from
uri="servlet:///helloWorld"> path
When created from path as <camel:from uri="servlet://helloWorld?name=test">
it gives XML error.
Can please suggest what should be the correct way to pass parameters from
'from' tag?
Thanks in advance,
Manoj

In XML the & should be defined as &
If not you can get xml parsing errors.
