Camel-Stream URI error

[Gnanaguru S]

Hi,

I created a route using camel stream. It worked fine. When I added the option ' scanStream ' . I was caught up witht this error.

[ERROR] Failed to execute goal org.apache.camel:camel-maven-plugin:2.9.2:run (default-cli) on project camel-ex
ample-osgi: null: MojoExecutionException: InvocationTargetException: Line 28 in XML document from file [D:\Cam
el\apache-camel-2.9.2\examples\camel-example-osgi\target\classes\META-INF\spring\camelContext.xml] is invalid;
 nested exception is org.xml.sax.SAXParseException: The reference to entity "scanStream" must end with the ';'
 delimiter. -> [Help 1]

This is my route: Please help.

<route>
      <from uri="stream:in:file?fileName=/input/test.txt&scanStream=true&scanStreamDelay=1000"/>
      <to uri="file://output"/>
    </route>

Hi,

I replaced & with ?. Working between different dsl's of camel. Got into confusion.

This is the modified working code.

<from uri="stream:in:file?fileName=/input/test.txt?scanStream=true?scanStreamDelay=1000"/>

Hi

In XML you cannot use & in the attributes, you must use an XML escaped
value as &amp;
So it should be

<from uri="stream:in:file?fileName=/input/test.txt&amp;scanStream=true&amp;scanStreamDelay=1000"/>

Hi Claus,

I am getting empty files when routing from stream endpoint.

I want to read each new line and update to other file.

My route:

Please share your view.

<camelContext xmlns="http://camel.apache.org/schema/spring">
    <route>
      <from uri="stream:in:file?fileName=//input//test.txt&amp;scanStream=true&amp;scanStreamDelay=1000"/> 
      <to uri="file://output"/>
<to uri="log:SUCCESS"/>
    </route>
  </camelContext>

Regards
Guru

What do you mean by empty files? Do you get an empty message?

Yes. Claus.I am getting empty message.

This is my scenario.

1. I have a log file( Txt file) it is getting updated from one system. I want to read every new line updated and write to a database.

2. Every time I should not read a file from first line, Hope you can understand.

3. Instead of a database, First am trying to write with a file.

Please help me how I can do this using Camel. I read file concepts in camel in action, But I was not able to get any idea for my use case.

Regards
Guru

Hi

I am not sure why you get empty lines. The components is using the API
from the JDK to read a line by line with code
   line = br.readLine();

If you can reproduce the issue, then I suggest to use a debugger in
the readFromStream method in the StreamConsumer, and see what is going
on.

Also it could be the fact that the other party is writing an empty
line to the file etc.
Also consider upgrade to a newer version of Camel and try out, to see
if that helps.
