Hi Christian

Thanks - and sorry for the somewhat rough tests. Currently I'm trying to
solve multiple problems at the same time 

And I tried it on 1.12.0 yesterday and there it works as you say. There
seems to be another problem with tracing on 1.12.0 though. When you activate
tracing using jmx console the tracing seems not to be invoked.

I haven't had the time to dig closer into it, so atm. take this only as a
hunch that there might be some problems here.

Best,
Preben

Re: org.xml.sax.SAXParseException: Premature end of file in split

[Preben.Asmussen]

Did 2 tests that shows the problem with enabling the tracer.

If you run RouteWithoutTracerTest it runs ok
The other RouteWithTracerTest fails with  org.xml.sax.SAXParseException:
Premature end of file.

The tracer seems to break stuff somewhere. 

tracerbug.zip
  

btw. run the tests separate in ide due to cxf test port conflicts. But that
another case.

Best,
Preben

Re: org.xml.sax.SAXParseException: Premature end of file in split

[Preben.Asmussen]

Well It didn't work as expected. 

After I added convertBody to byte[] the error persists when enabling
tracing.

Changed route ->





/ns4:now_previus_tracks_response/tracks_list/tracks

/tracks/ns3:channel/source_url


activemq:topic:music.playing.${in.header.channel}

${in.header.channel}
playliste-push-out

It seems that the tracer will read the cxf response stream when tracing gets
enabled resulting in an parseException.

This smells like a in camel-cxf ??

Btw the reason to convert the body to a byte array and not a string is that
the response is in utf-8 including bom.

Preben

Re: org.xml.sax.SAXParseException: Premature end of file in split

[Claus Ibsen]

Yeah converting to a String is a good idea if the data is in-memory
only, eg not a 500mb file you read from the file system etc.

A side note:
Also the xpath engine from JDK is purely in-memory only. It cannot
split / evaluate in streaming mode.

You can find some links about splitting big xml files on the Camel
articles page for solutions to this problem.

Re: org.xml.sax.SAXParseException: Premature end of file in split

[Preben.Asmussen]

Hi Willem

No the tracing was enabled using jmx to trubleshot. 
Thinking of it I recall some bug in Camel with a toString method and
streaming. It might be that when tracing is enabled it consumes the stream
when calling toString in camel version 2.10.0 ??

What would be the best approach here to avoid that ?
Upgrade or would converting to a String just before the split ?

Best,
Preben

Re: org.xml.sax.SAXParseException: Premature end of file in split

[Willem Jiang]

Hi,

Do you always enable to camel tracing in your production environment?

SaxParseException: Premature end of file.  It looks like a stream consuming
issue.
We need to know if the message is consumed before routing the splitter for
processing.
