camel-velocity and #parse() question

[Monica_G]

Hi,

I am using the camel-velocity component and want to call #parse() in my vm template.  However, I get the following exception:
org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource 'com/foo/bar/util/Header.vm'.  

Does anyone know how to resolve this?

Here is what I am doing:

In my RouteBuilder I have the following:

public void configure() throws Exception {
 //Note: the inputEndpoint and destinationEndpoint are set via spring injection
 from(inputEndpoint)
 .to("velocity:com/foo/bar/util/OrderXml.vm")
 .to(destinationEndpoint)
 .end();
}

In my vm template I have the following:
#parse("com/foo/bar/util/Header.vm")
<Order>
<order xml snipped...>
</Order>

I want to insert the Header.vm because I have some standard xml header info which I want to be able to reuse across xml files.

I've read the http://velocity.apache.org/engine/devel/developer-guide.html#configurationexamples page and I'm wondering if I need to set the 'file.resource.loader.path' value.  However I'm not sure how to do this through camel, or if this is even the right approach.

Thanks,

Monica

Hi Monica,

I think we can introduce a new parameter which accepts the velocity's
properties configuration.

I just created a JIRA[1] for it, before we resolved this issue, I don't
think current camel-velocity supports this configuration

Before that , I think you may try to let the message the velocity
endpoint twice.

from(inputEndpoint)
   .to("velocity:com/foo/bar/util/Headers.vm")
   .to("velocity:com/foo/bar/util/OrderXml.vm")
   .to(destinationEndpoint)
   .end();

And you OrderXml template can be
{Body}
<Order>
   <order xml snipped...>
   </Order>

Oh, the OrderXml template should be
  ${Body}
  <Order>
    <order xml snipped...>
    </Order> ...

BTW, I just wrote a simple test against the latest camel-velocity
component. There is a bug[1] of camel-velocity and a quick fix is coming up.

The template should be
${body}
   <Order>
     <order xml snipped...>
     </Order> ..
I just committed a quick fix for the CAMEL-2092.

Hello Willem,

Thank you for your reply and looking into the issue.

I just wanted to clarify that I'm not certain that passing in the Properties config file will solve my ResourceNotFoundException.  I think it may be the way to go, but I don't know for sure.

Thanks,

Monica

Hi Monica,

I just committed a patch[1] for the CAMEL-2091[2] which could make your
#parser work in Camel trunk (2.1-SNAPSHOT).
