Actually I have an issue, because in my procedure, I also use some
geotools plugin, i.e. the WFSDatastore, in order to get the
bounding box of a piece of feature collection from WFS, for which
I've built a separated method.<br>
This module depends on gt-opengis. Consequently I cannot run my
full java routine, either I cannot generate the metadata (if the
dependency gt-opengis is enabled), either i can generate the
metadata but I cannot use my custom bbox (if gt-opengis is
disabled).<br>
<br>
Would you have some example with ClassLoader that i could try to
apply?<br>
I thank you very much in advance for that.<br>
<br>
The other alternative for me, maybe would be to get the bounding
box from WFS filtered layer, using Geotoolkit and not
Geotools/WFsDatastore.<br>
Would it be possible with Geotoolkit? In this case, it would allow
me do not depending anymore on gt-opengis.<br>
<br>
For information this is the method I used with Geotools:<br>
<br>
<i>/** Get Species Distribution BBOX</i><i><br>
</i><i> * </i><i><br>
</i><i> * @param alphacode</i><i><br>
</i><i> * @return</i><i><br>
</i><i> */</i><i><br>
</i><i> public static ReferencedEnvelope
getSpeciesBoundingBox(String alphacode){</i><i><br>
</i><i> </i><i><br>
</i><i> try{ </i><i><br>
</i><i> //WFS feature collection</i><i><br>
</i><i> Map<String, Serializable> params = new
HashMap<String, Serializable>();</i><i><br>
</i><i> params.put(WFSDataStoreFactory.URL.key,
"MyWFSGetCapabilities");</i><i><br>
</i><i> params.put(WFSDataStoreFactory.TIMEOUT.key, new
Integer(60000));</i><i><br>
</i><i> </i><i><br>
</i><i> datastore =
DataStoreFinder.getDataStore(params);</i><i><br>
</i><i> featureSource =
datastore.getFeatureSource("mylayer");</i><i><br>
</i><i> </i><i><br>
</i><i> String cql = "attribute='"+value+"'";</i><i><br>
</i><i> Filter filter = CQL.toFilter(cql);</i><i><br>
</i><i> Query query = new Query("mylayer",filter);</i><i><br>
</i><i> SimpleFeatureCollection sfc =
featureSource.getFeatures( query );</i><i><br>
</i><i> </i><i><br>
</i><i> </i><i><br>
</i><i> //bounds calculation</i><i><br>
</i><i> ReferencedEnvelope bounds = new
ReferencedEnvelope();</i><i><br>
</i><i> SimpleFeatureIterator iterator =
sfc.features();</i><i><br>
</i><i> try {</i><i><br>
</i><i> while( iterator.hasNext() ){</i><i><br>
</i><i> SimpleFeature feature = (SimpleFeature)
iterator.next();</i><i><br>
</i><i> bounds.include(feature.getBounds());</i><i><br>
</i><i> }</i><i><br>
</i><i> System.out.println( "Calculated Bounds:"+
bounds );</i><i><br>
</i><i> }</i><i><br>
</i><i> finally {</i><i><br>
</i><i> if(iterator!=null){</i><i><br>
</i><i> iterator.close();</i><i><br>
</i><i> }</i><i><br>
</i><i> </i><i><br>
</i><i> }</i><i><br>
</i><i> return bounds;</i><i><br>
</i><i> }catch(Exception e){</i><i><br>
</i><i> throw new RuntimeException("impossible to get
bbox");</i><i><br>
</i><i> } </i><i><br>
</i><i> </i><i><br>
</i><i> }</i><br>
<br>
Otherwise, do you know what is the status of what you precised
below regarding Geotools? Do you know if Geotools developers
intend to change this, or not?<br>
Do you think would be good to copy as well to the geotools-dev
mailing list to get their feedback?<br>
<br>
Thanks again<br>

The fact is that i'm also using GeoTools. And t seems there was
a conflict with the gt-opengis library...To test, i've excluded
this dependency, and it works fine.

<br>
Yes, this is a known problem... GeoTools should change the package
name of their interfaces, since they do not own the "org.opengis"
namespace and do not participate to the OGC working group. It may
be possible to allow the two libraries to co-exist with some
tricky ClassLoader use, but I'm not sure if it would really work.
