[Geoserver-devel] Implements ows troubles with Post Data

meierchen · April 2, 2012, 9:54am

Hello,
I want to realize a own ows plugin. The KVP parsing by HTTP Get is no
problem.
But when I want to use XML Post I cant fetch the Post-Data.
I use request.getInputstream but it returns me no Information also i try it
with reset/mark but it gives a exception that it is not allowed.
I checked all methods from request Object but the Post-Data is lost.
But getContentLength() gives me the correct size of the HTTP-Request.
In my opinion the ows.Dispatcher work not correctly.
So what can i do?

Ps: Sorry for my bad english

Hi,

The way ows services handle posted xml data is by registering an instance of org.geoserver.ows.XmlRequestReader in the spring context. That object must parse the xml into some object, which the dispatcher will then pass into the ows service request. Look at the wfs module for some examples.

Hope that helps.

Dear all,

I would try to develop a Geoserver DataStore plugin for a legacy database, which has no spatial extension, and for the beginning it would be ok, to have it read-only. I would need to limit some SQL queries with some clauses to not expose all features, but only those that fit some criteria.
And my actual question is, how do I finally compile and package the plugin? Do I need the whole Geoserver or Geotools source? Can I do that with maven, with simply working in the hierarchy like http://svn.osgeo.org/geotools/trunk/modules/unsupported/myModule (I would derive from a simple existing one) ?

Best,
Alex

Hi Alex,

You should only need the geotools sources. And you should be able to use straight maven. There is a good guide for this in the geotools documentation.

http://docs.geotools.org/stable/userguide/quickstart.html

Should be a good place to start.

Hi Justin,

thanks, yay, so at least one time building whole geotools and download all the maven dependencies and then actually starting to develop on the plugin, right ?

Thanks, I just was not sure, wether to really build all geotools at first.

Best,
Alex

This is how most core developers work yes. But again if you don’t want to build geotools locally you can just depend on them via maven. A workflow i recommend is this.

Set up your project to depend on geotools via the geotools quickstart
Do a full build of your template project, this will download all the geotools jars and its dependenices
Develop
Do “offline” builds to avoid continually download geotools snapshots (-o switch to maven)

Hi Justin,

thanks, worked fine, did the complete build, had some issues with imageio and jai libs, but I skipped some tests and thats fine, as I am just going to fiddle with some simple vector features around

Cheers,
Alex
