mapfishapp - print spec does not contain the WMS version

[fvanderbiest]

By default, the mapfish print module assumes WMS = 1.1.1

If the server supports only 1.3.0, the layer is not printed (eg: the French IGN's geoportail WMS layers).

[fvanderbiest]

See mapfish-print issue mapfish/mapfish-print#97

[fvanderbiest]

I've hacked the client side so that it sends the WMS version parameter in the print spec, but this is not enough to get the GeoPortail layers printed.

Here are the relevant mapfish-print logs:

Looks like the referer that is sent by the module is not accepted by the remote server, which expects a valid URL like http://dev.geopicardie.fr/ rather than simply dev.geopicardie.fr

Got it!

See http://docs.geoserver.org/latest/en/user/services/wms/basics.html#differences-between-wms-versions for the major differences.

A new snapshot is online and should be tested.

Nice, testing right away !
Thanks Jesse.

Does not work for this layer http://dev.geopicardie.fr/mapfishapp/?wmc=ws%2Fwmc%2Fgeodoc5363636713352030312.wmc on this platform.

I found one bug which will hopefully fix your issue and uploaded it to both maven snapshots directory and to dev.mapfish.org maven repository.

Please try again and let me know if it works.

[fvanderbiest]

I'm using the latest print lib:

d542f541e49830eddf3ee2c0aa228f0d  .m2/repository/org/mapfish/print/print-lib/2.0-SNAPSHOT/print-lib-2.0-SNAPSHOT.jar
d542f541e49830eddf3ee2c0aa228f0d  /path/to/tomcat/webapps/mapfishapp-private/WEB-INF/lib/print-lib-2.0-SNAPSHOT.jar

but the request still uses the old SRS parameter :-(

[jesseeichar]

That does not seem to be the latest version:

ac22d95ae4ea00a29492f9c4a00e636d

is the md5 of the latest. See:

https://oss.sonatype.org/content/repositories/snapshots/org/mapfish/print/print-servlet/2.0-SNAPSHOT/

for the latest.

[fvanderbiest]

OK, now I get something printed, but not the area I expected.

Fixed with the latest print release. Kudos to @jesseeichar for fixing that (and also for adding many tests to the mapfish print module).

You may have to remove your /home/build_user/.m2/repository/org/mapfish/print folder before building again.
