Internal pipeline with a reader

[Zhu Di <fl...@gmail.com>]

I try to use coccon:\\ to call the pipeline in another application, but for
html it works fine, but for PNG (using reader), it couldn't work. I got the
error message as

Streaming of an internal pipeline is not possible with a reader.

how can I make it works for PNG file


I have two application under cocoon: test1 test2

in test1 sitemap:

<map:match pattern="ext/**/*.html">
  <map:act type="serverpages" src="......">
    <map:generate src="cocoon://test2/*.html"/>
  </map:act>
  ......

</map:match>

<map:match pattern="ext/**/*.png">
  <map:generate src="cocoon://xa-xq/framed/{4}/{5}/{1}/{6}/png/{7}.png"/>
  <map:act type="serverpages" src="......">
    <map:generate src="cocoon://test2/*.png"/>
  </map:act>
  ......

</map:match>



in test2 sitemap:

<map:match pattern="*.html">
  <map:generate ...>
  <map:serializer ..>
</map:match>

<map:match pattern="*.png">
  <map:read src="png/{1}.png" mime-type="image/png"/>
</map:match>
