Apache SIS Database 'classpath:SIS_DATA/Databases/SpatialMetadata' not found

Question

When I try to initialize a org.apache.jena.geosparql.implementation.SRSInfo Object in a JUnit test function, I got an java.lang.ExceptionInInitializerError, the stack trace is:

Caused by: java.lang.ArrayStoreException: org.geotools.referencing.factory.epsg.FactoryUsingWKT

I tested the CRS.forCode function directly, but got the same error.

The derby.log file shown that there is an exception

java.sql.SQLException: Database 'classpath:SIS_DATA/Databases/SpatialMetadata' not found.

Caused by: ERROR XJ004: Database 'classpath:SIS_DATA/Databases/SpatialMetadata' not found.

I have added the maven dependency sis-embedded-data

 <dependency>
      <groupId>org.apache.sis.non-free</groupId>
      <artifactId>sis-embedded-data</artifactId>
      <version>1.0</version>
      <scope>runtime</scope>
 </dependency>

I have also tried to add the sis-epsg dependency and set the SIS_DATA environment variable, but got similar error.

<dependency>
    <groupId>org.apache.sis.non-free</groupId>
    <artifactId>sis-epsg</artifactId>
    <version>1.0</version>
    <scope>runtime</scope>
</dependency>

Any idea to fix this problem?

Answer 1

This problem may be caused by the conflicts between Apache SIS and Geotools libraries. I have created a clean environment to test this porblem, and it worked without exceptions. So, I excluded geotools libraries and got the right answer!
