Hello,
I have recently upgraded from XStream1.1.2 to 1.4.2 to overcome a problem
that appeared when running my java application with java7.
However, when I now try to load a data object that was saved using XStream
1.1.2 I am getting the following Error message, concerning one of my data
structures that is derived from java.util.Hashtable:
---- Debugging information ----
message : Could not call
edu.tau.compbio.util.OrderedHash.readObject()
cause-exception :

-------------------------------
I have tried adding the following code to my OrderedHash class:
private void writeObject(ObjectOutputStream oos) throws
IOException {
System.out.println("writing...");
oos.defaultWriteObject();
System.out.println("wrote...");
}
private void readObject(ObjectInputStream ois) throws IOException,
ClassNotFoundException {
System.out.println("reading");
ois.defaultReadObject();
System.out.println("read");
}
This did not solve the problem.
I also tried adding the code
xstream.setClassLoaded(new CompositeClassLoader());
right after creating the xstream object but no luck there either.
Any suggestions will be most appreciated....
Thanks
Adi
