Error importing system routines Geometry

Anonymous — Fri, 28 Dec 2018 16:04:53 GMT

Hello,

I am having an issue on using the Geometry routines in Talend.

I have two projects :

- one on them os working just fine, using same routines

- the other one shows the following errors :

- org.geotools.referencing.CRS cannot be resolved to a type : in GeometryOperation

- org.geotools.gml3 cannot be resolved to a type : in GeometryUtility

I have tried putting both projects in the same workspaces, then in separate ones. The only difference between projects is that the one with error has user defined routines, can it be the source of the problem?

I have tried everything I could think of, thank you for your help...

Ok so after making new tests, I realised that a routine of mine creates the problem on the system routines : adding the library gt-opengis-8.5 to my routine makes the system routines GeometryUtility and GeometryOperation uncompilable ...

Does anyone know what is going how and how to bypass the problem?

Thanks

if same jar is troubling , we could use an custom class loader only for specifc functionality.

please explore URLclassloader option for your lib jar.

i am not sure if this will help but worth a try.

Thank you for your reply.

I have tried this :

          Class ClassSF= new URLClassLoader(new URL[]{new File(pathToJar).toURI().toURL()}).loadClass("org.opengis.feature.simple.SimpleFeature");
          Class ClassSFT= new URLClassLoader(new URL[]{new File(pathToJar).toURI().toURL()}).loadClass("org.opengis.feature.simple.SimpleFeatureType");
          Class ClassAD= new URLClassLoader(new URL[]{new File(pathToJar).toURI().toURL()}).loadClass("org.opengis.feature.type.AttributeDescriptor");

But I don't know how to invoke it, I still have an error on :

SimpleFeatureSource featureSource = dataStore.getFeatureSource();

The type org.opengis.feature.type.Name cannot be resolved. It is indirectly referenced from required .class files

I am not very good in java, do you have an idea?

Thanks!
