Hello all,
I am running GeoServer 2.4.3 on Centos 6 using Tomcat6.
Java version 1.7.0_51 OpenJDK
I am trying to install and use the DynamicColorMap community extension. I extracted the jar in to WEB-INF/lib and restarted the server as usual. On the restart I am receiving this error:
2014-04-10 21:14:42,655 INFO [geoserver.wps] - Blacklisting process ras:DynamicColorMap as the input colorRamp of type interface org.geotools.styling.ColorMap cannot be handled
Any thoughts?
Thanks.
Perhaps version incompatibility (did you use a 2.4.3 community module?)
Other than that please try Java 6 - Java 7 is not officially supported yet (something we are looking at changing shortly).
To be fair - the community modules are experiments by the developers (shared in order to attract feedback and funding) and are not recommended for production

The process is meant to be used as a rendering transformation in SLD, it
was not developed to be used as a stand alone process,
as such, it misses the PPIO class that can parse/encode the input color
ramp.
The good news is, it should not be that hard to develop one
About not using it in production, quality varies a lot among community
modules, they indeed range from non working experiments
to modules that are being used in anger, but do not yet satisfy all the
requirements for graduating to official extension (e.g.
see this proposal for a list of requirements that need to be satisified to
graduate a module:
http://geoserver.org/display/GEOS/GSIP+105+-+Promote+importer+module+to+extension+status
)
This one has been in production in a scientific app for a few months now,
but it does not qualify yet for extension, one of the
requirements is that it needs 3 known users, so far it has one.
It is indeed true, though, that a module staying for a long time in
community land tends to rot over time, as it's not normally
even built (as such, it can stop compiling or passing tests without any
warning).

Hi Andrea,
I am using in the SLD as per the instructions in the GeoServer User Manual. But I have gotten a variety of error messages including:
NullPointerException
java.lang.RuntimeException: Unable to find function gridCoverageStats
java.lang.NoSuchMethodError: org.apache.commons.io.filefilter.FileFilterUtils.and([Lorg/apache/commons/io/filefilter/IOFileFilter;)Lorg/apache/commons/io/filefilter/IOFileFilter;
So I tried to trace back through the log files and found the blacklisting. At that point I figured I should ask for help before trying to dig into the code.
I know it’s still a community extension, but I have a temperature data set in and ImageMosaic so the color ramp that works for 9000 pa is useless at 1000 pa and accommodating both is not a great solution. So I was really happy when I saw this extension. I’m hoping you have a suggestion? Could it be the Java version?

No idea, I've never used it myself. Daniele probably knows better and/or
can share an example

Hi Benjamin,
not sure about java version. We only tested it on Java 6.
I have never seen that blacklisting issue before.
Did you get that issue even before defining any SLD, and generating stats on your sample mosaic, just after having deployed the community jar and restarted geoserver?
Please, let us know.
Cheers,
Daniele
