Can i render content (css) of ContextRelativeResource to markup?
Hi,
I like to render a PDF by my wicket page using flying-saucer. There i reference my css file by url (link). So far everything works.
But if i switch to SSL flying-saucer breaks. Hmm.
My solution to this issue would be to include content of my css file directly in the wicket-page used to render the pdf.
I tried to get the resource and render it in markup like this
<code>
MyPage.java
@Override
public void renderHead(IHeaderResponse response) {
IResource s = new SharedResourceReference("report.css").getResource();
Attributes a = new Attributes(getRequest(), getResponse());
s.respond(a);
super.renderHead(response);
}
</code>
but i get
at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:608)
at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:543)

It seems that my ContextRelativeResource only provides content as byte[] ans StringResponse not supporting this.
Maybe i be off the track.
Thanks for your support

Hi Heiner,
the Server needs to support Servlet 3.0 Spec. It seems that you are using one which does not support that.

Hi,
The error says that the container needs servlet-api:jar:3.0 while the
application comes with older version of the jar.
I don't use GAE myself so I have cannot give you more info.

hi, appengine has a quite confusing versioning policy. The last version
supporting java 6 (hence not requiring servlet 3) is 1.8.1 so if you use
this version or an earlier one you should be ok. Unfortunately l also don't
use appengine as deployment environment so l can't help you more in detail.

Re: Can i render content (css) of ContextRelativeResource to markup?
Posted by Martin Grigorov <mg...@apache.org>.
Hi,
You should use response.render(CssHeaderItem.forCSS(string)). This will
contribute it in <style> HTML element. With your approach it will be plain
text in the middle of the HTML.
To get the "string" you can use new
WebExternalResourceStream("report.css").getInputStream(),
read, convert to String, close.
