Hi:
I'm developing a Grid Service in which some EPRs are Resource Properties. So,
I'm trying to get persistence saving them in a file. Following the "Globus
Toolkit 4: Programming Java Service", I develop both store() and load()
functions in the Resource.java.
The store() is OK with the following Serialization:
FileOutputStream fos = null;
File tmpFile = null;
// Statements associated with the EPR RP
EndpointReferenceType[] EPRList = getEPR();
String[] endpointString;
String NS =
"http://org.merrill/namespaces/examples/Service";;
QName RESOURCE_REFERENCE = new
QName(NS,"ResourceReference");
// Temporal file .temp creation
tmpFile = File.createTempFile("file", ".temp",
getPersistenceHelper().getStorageDirectory());
fos = new FileOutputStream(tmpFile);
// RPs are written in the temporal file
ObjectOutputStream oos = new ObjectOutputStream(fos);
//EPR needs to be serialized
endpointString = new String[EPRList.length];
for (int i = 0; i < EPRList.length; i++){
endpointString[i] =
ObjectSerializer.toString(EPRList[i], RESOURCE_REFERENCE);
}
oos.writeObject((String[]) endpointString); //It is
written as a String[]
oos.close();
But I don't know how to retrieve the EPRs in the load() function. I don't know
how to use the ObjectSerializer or ObjectDeserialize to get back the EPRs
because I don't find the reverse method. Can anybody help me?
thanks
Carlos
