[Geoserver-devel] Building and loading WPS extension

GeoServer GeoServer Developer
1

I am trying to create a new WPS process, so I have downloaded Geoserver from master branch and then I have compiled it using:

mvn -DskipTests -Pwps clean install

Then I have executed Geoserver using jetty from Maven, but the WPS extension doesn’t seem to be loaded (WPS is not listed on the Service Capabilities as it is stated on the manual 1).

Do I need to do something else in order to enable the extension?

Thanks in advance,

César

Sorry, I forgot 2 details that might be useful:

  • I am using Java 1.6 32 bits (on a 64 bits machine)

  • The following message appears on log: “15-abr-2014 16:11:29 org.geoserver.platform.GeoServerExtensions checkContext
    ADVERTENCIA: Extension lookup occured, but ApplicationContext is unset.”

Thanks,

César

I don't normally run jetty from maven, but to have WPS included I believe
you have to run it like this:

mvn jetty:run -Pwps

Thanks Andrea, your suggestion works correctly. I thought it was only needed for compiling. How can I provide the equivalent parameter from within Eclipse?

I am also getting a java.lang.NoClassDefFoundError: java/nio/channels/SeekableByteChannel on WMS getCapabilities when running with Sun Java 1.6. It seems to work fine with OpenJdk 1.7.

Is Java 6 already unsupported?

Best regards,

César

It will be in a few days on the development series (master branch). Not
sure why you're getting that error though

I couldn't help notice this:

This is an issue that appears when compiling with java7 but using java6
source/target - while the class files are java6 compatible, the runtime
required is not. This has happened with previous versions of java, but I
can't recall the specific versions or classes involved.

Long story short, if you want to run on java6, compile w/ java6.

Thanks Ian and Andrea for your answers.
I though I was building with 1.6, so I will review my environment when I get a free time slot.

For the moment, it is running fine with OpenJdk 1.7.

Regards,

César
