Meine Anwendung funktionierte auf meinem lokalen Tomcat-Server. Später habe ich es jedoch in WebSphere implementiert, indem ich eine WAR-Datei erstellt habe. Nach der Bereitstellung, wenn ich versuche, einen Aufruf an die gespeicherte Prozedur mit dem StructDescriptor wie folgt zu starten, erhalte ich ClassCastException. mein Code-Segment folgend:ClassCastException of StructDescriptor auf websphere, aber nicht auf tomcat
StructDescriptor projectTypeDesc = StructDescriptor.createDescriptor(
"FRA_DATA.REGION_TYPE", st.getConnection());
STRUCT[] structs = new STRUCT[filterDTO.getRegion().size()];
for (int i = 0; i < filterDTO.getRegion().size(); ++i) {
int str = (int) filterDTO.getRegion().get(i).intValue();
Object[] objects = new Object[] { str };
STRUCT struct = new STRUCT(projectTypeDesc, st.getConnection(),
objects);
structs[i] = struct;
}
ArrayDescriptor arrayDescriptor = ArrayDescriptor.createDescriptor(
"FRA_DATA.REGIONS", st.getConnection());
arrayList.add(new ARRAY(arrayDescriptor, st.getConnection(), structs));
Und die Fehler, die ausgelöst wird, ist:

Das Objekt, das in der Datenbank erstellt wurde, ist wie folgt:
CREATE OR REPLACE TYPE region_type AS OBJECT (region NUMBER);
CREATE OR REPLACE TYPE regions AS TABLE OF region_type;
habe ich versucht, nach verschiedenen Formen zu suchen und keine Lösung gefunden. Bitte helfen Sie.
