Example 10 with DependencyException

use of loci.common.services.DependencyException in project bioformats by openmicroscopy.

the class ZeissZVIReader method initPOIService.

private void initPOIService() throws FormatException, IOException {
    try {
        ServiceFactory factory = new ServiceFactory();
        poi = factory.getInstance(POIService.class);
    } catch (DependencyException de) {
        throw new FormatException("POI library not found", de);
    }
    poi.initialize(Location.getMappedId(getCurrentFile()));
