How to access a classpath file from a bean

larasith Sep 30, 2010 7:32 AM

I need to access a file from a bean of my routing, but i always get the same error:

java.io.FileNotFoundException: classpath:apns.p12

My file is in src/main/resources, do anyone know how to reference it?

Hi,

Have no idea about your whole scenario.
Could you please provide more info about this issue?

Something like more details about your user scenario, which smx version you are using, which component get involved etc.

Do you want reference a file from another bundle, or in same bundle? Or you didn't use bundle at all?

hi, my routing is the following:

i tried with several certificate path:

apns.p12
classpath:apns.p12
classpath:/apns.p12

in my project, this file is under:

src/main/resources

and i'm trying to access it through:

FileInputStream fin = new FileInputStream(certificatePath);

Hi,

So all stuff is in same bundle? The camel router, Pusher Bean and apns.p12?

If you need to load from the classpath you should load it as such. The FileInputStream is for loading from file system (eg not classpath).

But since its in the same bundle you may be able to load it using regular JDK load resource from classpath stuff. Just google at bit how to do that.

In Camel we have a ClassResolver which we use to load resources from classpath. It allows us to do this regardless if we run on OSGi, JBoss (have its own classloader thingy), WebSphere etc.

CamelContext.getClassResolver(). And it has methods to load resources, such as loadResourceAsStream

Just add CamelContext as parameter to your method, and Camel will automatic provide it to you when the method is invoked by Camel.
