I have two persistable classes: test.test1.Test and test.test2.Test,
but I can't persist/query objects of these classes right. There is a
simple example shows wrong behavior:
test.TestServlet.java:
package test;
import java.io.IOException;
import javax.jdo.JDOHelper;
import javax.jdo.PersistenceManager;
import javax.jdo.PersistenceManagerFactory;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class TestServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse
response) throws IOException {
PersistenceManager pm = pmFactory.getPersistenceManager();
pm.makePersistent(new test.test1.Test("1", "test1"));
pm.close();
pm = pmFactory.getPersistenceManager();
pm.makePersistent(new test.test2.Test("1", "test2"));
pm.close();
pm = pmFactory.getPersistenceManager();
response.getWriter().println("RESULT: " + pm.getObjectById
(test.test1.Test.class, "1"));
pm.close();
}
public static final PersistenceManagerFactory pmFactory =
JDOHelper.getPersistenceManagerFactory("transactions-optional");
}
test.test1.TestServlet.java and test.test2.TestServlet.java are the
same except package name, so I missed it:
import javax.jdo.annotations.*;
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Test {
public Test(String id, String data) {
this.id = id; this.data = data;
}
public String toString() {
return getClass().getName() + ": id=" + id + " data=" + data;
}
@PrimaryKey
private String id;
@Persistent
private String data;
}
Surprising result I got is following:
RESULT: test.test1.Test: id=1 data=test2
Expected result:
RESULT: test.test1.Test: id=1 data=test1
