Problem with TypeConverters in OSGi
Hi,
I tried deploying some of my existing Camel routes into an OSGi enviroment
(Camel 1.3.0 / ServiceMix 4 Kernel / Apache Felix) and I noticed that all of
the TypeConverters stopped working, even the basic ones (e.g. byte[] to
String). I found this error in the log:
18:26:04,982 | ERROR | ExtenderThread-4 | ResolverUtil |
g.apache.camel.util.ResolverUtil 364 | Could not search jar file
'/org/apache/camel/converter' for classes matching criteria: annotated with
@Converterdue to an IOException: /org/apache/camel/converter (No such file
or directory)
I guess ResolverUtil tries to find and open the .jar file but gets confused
if the package is in an OSGi bundle. I checked the camel-osgi module, but it
only seems to add support for searching for Camel components in active OSGi
bundles, and not TypeConverters.
Is there a way to fix this?
Thanks,
Ivan

OSGi is a kinda different beast though ...
I'll try to have a look at that.

Hi
Try adding log4j trace level debugging as Camel ResolverUtil does trace logging while it tries to load the class ressource.
And for fix of the bug could potential look how Spring does ressource loading as they have fought with all kind of weird situations with loading from WebSphere, WebLogic, JBoss etc. that does strange tricks

Hi,
I tried using this Camel route builder:
package test;
import org.apache.camel.builder.RouteBuilder;
public class MyRouteBuilder extends RouteBuilder {
public void configure() throws Exception {
from("timer://myTimer?period=2000")
.setBody(constant(new byte[]{'H','e','l','l','o'}))
.convertBodyTo(String.class)
.to("log:Test");
}
}
Running it in normal Java SE (without OSGi) I get correct log output:
INFO: Exchange[Message: Hello]
Runing it inside SMX Kernel, I get:
12:51:02,415 | ERROR | xtenderThread-28 | ResolverUtil |
er.AnnotationTypeConverterLoader 58 | Could not search jar file
'/org/apache/camel/converter' for classes matching criteria: annotated with
@Converterdue to an IOException: /org/apache/camel/converter (No such file
or directory)
[...]
12:51:06,449 | INFO | myTimer | Test|
che.camel.impl.ProcessorEndpoint 72 | Exchange[Message: [B@11dfada]
It should be 'Hello' instead of '[B@11dfada]'
Btw, I also just noticed that if I define my OSGi CamelContext with Spring
like this:
<osgi:camelContext xmlns="http://activemq.apache.org/camel/schema/spring">
<package>test</package>
</osgi:camelContext>
I also get an error:
13:08:06,790 | ERROR | xtenderThread-33 | ResolverUtil |
.camel.spring.RouteBuilderFinder 73 | Could not search jar file '/test'
for classes matching criteria: is assignable to RouteBuilderdue to an
IOException: /test (No such file or directory)
and no routes get created. Instead I had to use:
<osgi:camelContext/>
<bean class="test.MyRouteBuilder" />
Let me know if there is anything else I could do to help.
Thanks,
Ivan

Thx, could you give some informations on how to reproduce the problem ?
Maybe the code of a simple OSGi bundle that fails ?
