I got the AccessControlException on the following code snippet:
public void add(List<String> iriList, List<String> nameList,
List<String> imageList) {
// deleted for brevity
try {
datastore.put(eList); // The log
below shows this line as at
com.col.server.MDsIri.add(MDsIri.java:74)
} catch (IllegalArgumentException exIA) {
logger.severe("IllegalArgumentException when trying to
datastore.put. Exception message: " + exIA.getMessage());
} catch (ConcurrentModificationException
exCM) {
logger.severe("ConcurrentModificationException when trying to
datastore.put. Exception message: " + exCM.getMessage());
} catch (Exception ex) {
logger.severe("Exception when trying
to datastore.put. Exception
message: " + ex.getMessage()); // the log (last line) below says that
the message is unknown
}
}
// deleted for brevity
}
I follow the guideline that the eList has only 500 entities at most as
mentioned on
http://code.google.com/appengine/docs/java/datastore/overview.html#Quotas_and_Limits.
Also, I don't call any thread or system threads as mentioned on
http://code.google.com/appengine/docs/java/runtime.html#The_Sandbox.
I did not get the error below on my Development Server.
I don't know how to interpret the error because the exception/error
message is Unknown(last line of the log).
I appreciate any help.
