Hello!
Please, could anybody give me a simple _step-by-step_ instruction of
how to select long Strings(Text) from Datastore?
Here is my Database Object:
*************************
@PersistenceCapable(identityType = IdentityType.APPLICATION,
detachable="true")
public class Captions {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
/*
@Persistent(serialized="true", defaultFetchGroup="true")
private Text captions_label;
*/
@Persistent(serialized="true", defaultFetchGroup="true")
private Blob captions_label;
*************************
I've tried both "new Text(myString)" and "new Blob(myString.getBytes)"
to store in these fields, but no luck.
I always get an Exceptions either ClassCast like "String cannot be
casted to Blob", or "There is a String inside Datastore, but must be
Blob" or something similar.
Please, give me a code sample, it should not be a very difficult task.
I'm wasted 2 days and... got nothing :-|
Please, help.
