Subject [jira] Commented: (CAMEL-782) Tracer incorrectly treats messages with InputStream as body
Date Wed, 06 Aug 2008 04:15:52 GMT

Claus Ibsen commented on CAMEL-782:
-----------------------------------

Ah good catch. The logger could have the same problem as well.

I remember there is something with streamcache that might can help out here. I don't have
the time to dig into it yet.

A workaround is to disable logging of the body in the tracer. There are options for this in
the formatter:

> Suppose we have the following flow:
>  from("activemq:vasea")
>   .to("cxf:bean:serviceEndpoint?dataFormat=MESSAGE")
>     .unmarshal().string()
>   .to("activemq:petea");
> In this flow cxf:bean:serviceEndpoint returns ByteArrayInputStream as body. Under normal
conditions everything works fine: WS output gets to the queue.
> But if we add:
> getContext().addInterceptStrategy(new Tracer());
> Queue starts receiving empty messages. After digging in the code I found out that tracer
reads input stream in order to display body, but not resets it. Thus when message reaches
unmarshaller, nothing could be read from the stream.
