Hi list,
I've encountered something strange.
We have a webapplication in which we use a wms layer from geoserver
(2.14.0). In that webapplication we create a filter (spatial and/or
attribute) from which we create a SLD. We put a URL to that SLD in the
getmap request.
When the sld is located on an external server, everything is fine, but
when it's on the same server we get the error message in the
responseimage "Error while getting SLD. See the log for details". The
logs are [1].
When inspecting SLDHandler on 140, it seemed that the method
getVersionAndReader(input) returned a null, probably because of [2]. So
I've commented out that check, recompiled and put the new .class files
into the war and deployed it, and then it worked.
The network setup is as follows:
internet <--> apache on server 1 <---> apache on server 2 <---> tomcat
(with geoserver in it) on server 2
Traffic from server 2 to server 2, is a direct connection (not routed
via server 1).
When the sld resides on the internet, everything is fine.
When the sld resides on server 2, and routed via apache, we get the error.
When the sld resides on server 2, but accessed directly via the tomcat
http connector, it works.
Our conclusion was that the apache on server 2 does something weird.
So, three questions:
1. Why is the check BufferedReader.ready() done? You can still read from
the reader.
2. Will removing this check break something else?
3. Any ideas why BufferedReader.ready() returns false when routed
through apache?
If needed I'm happy to make a PR, removing that check.
Thanks in advance!
Kind regards,
Meine Toonen
