    BUG: FindByPrimaryKey fails to find object when using compou

    Jordan Zommick Newbie

      I'm using JBoss 3.0 production release with CMP. I'm using a compound key. I can use a findAll which returns a collection of my beans; however, when I do a findByPrimaryKey(myKeyPK), it says the object is not found even though it is found in the findAll method.

          One explanation might be that you have forgotten to write the equals and hashcode methods in your primary key class. (Or have a but in them somewhere).

            As you can see, the hashcode and equals appear to be fine.

            public class RequestPK implements java.io.Serializable {

            public Integer requestId;
            public Integer recordingId;

            public Integer getRequestId() {
            return requestId;
            }

            public Integer getRecordingId() {
            return recordingId;
            }

            public boolean equals(Object obj) {

            if (obj == null || !(obj instanceof RequestPK)) {
            return false;
            }

            RequestPK other = (RequestPK)obj;
            if ( this.requestId.intValue() == other.requestId.intValue()
            && this.recordingId.intValue() == other.recordingId.intValue() ) {
            return true;
            }
            else {
            return false;
            }
            }

            public int hashCode() {
            return (requestId.intValue() + " " + recordingId.intValue()).hashCode();
            }

            public String toString() {
            return requestId.intValue() + " " + recordingId.intValue();
            }

            public RequestPK() {}

            public RequestPK( Integer requestId, Integer recordingId ) {
            this.requestId = requestId;
            this.recordingId = recordingId;
            }
            }
