I am using ISIS 1.3.0 with JDO 3.0.1, Data Nucleus 3.2.4
Using JDO Application Identity strategy, I have a composite PK class with two
attributes(PK fields of type String).
As per the JDO specifications, PK class has overridden the following methods:
hascode, equals and toString.
And it has Constructor which takes String parameter.
Problem is that for some Entities OID is not found if any of the PK fields has
the same character which is used to join in the toString method
For example: Consider the below PK class:
public class OmGeoLocationPK implements java.io.Serializable {
public String locationId;
public String orgId;
public OmGeoLocationPK() {
}
public OmGeoLocationPK(String locationId, String orgId) {
this.locationId = locationId;
this.orgId = orgId;
}
public OmGeoLocationPK(String key){
StringTokenizer token = new StringTokenizer(key, "_");
this.locationId = token.nextToken();
this.orgId = token.nextToken();
}
public String getLocationId() {
return this.locationId;
}
public void setLocationId(String locationId) {
this.locationId = locationId;
}
public String getOrgId() {
return this.orgId;
}
public void setOrgId(String orgId) {
this.orgId = orgId;
}
public String toString() {
return "" + locationId + "_" + this.orgId;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result
+ ((locationId == null) ? 0 : locationId.hashCode());
result = prime * result + ((orgId == null) ? 0 : orgId.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
OmGeoLocationPK other = (OmGeoLocationPK) obj;
if (locationId == null) {
if (other.locationId != null)
return false;
} else if (!locationId.equals(other.locationId))
return false;
if (orgId == null) {
if (other.orgId != null)
return false;
} else if (!orgId.equals(other.orgId))
return false;
return true;
}
}
Here in the toString method "_" character used to join two PK fields
(locationId and orgId).
So, if locationId or orgId has the chracter "_" in its S
tring value, Splitting with StringTokenizer is not evaluating the correct PK
feilds values and it throws the following exception:

Actually, locationId is: ORG_FILTER_TEST and orgId is : ATL.
But after tokenizing with "_" OID evaluated as
ORG_FILTER as locationId has "_" in it.
So I tried with other characters which would not be expected in those fields
like ":" (colon), "::"(double colon). But these characters are not supported.
And I got the exception coming from OIDMarshaller of ISIS
