    cursor woes

      hello all.

      sorry for such a noob question ... but new to berkeley db je.

      i am using the base api, and have basic db creation and insertion (serialized objects) working.

      when i go to retrieve data, i can get single items just fine.

      but when i try to make a cursor, and iterate though the cursor (say with getNext())
      the first few records found seem to be ?garbage?

      if i skip over them, with something like
      int loop = 0;
      while( myCursor.getNext( key, data, LockMode.DEFAULT ) == OperationStatus.SUCCESS ){

      if( loop <= 2 ){

      // de-serialize here ...


      then the de-serialize works great, and i am de-serializing all the items that i 'think' put 'in' (ass/u/ming i am not the one putting in the garbage).

      without the skipover i get corrupted stream errors, i think the data value is null that i am passing into the

      mmm ... couple of hints

      i am running in memory only mode.
      i open the db(s) and env.
      load the db.
      try to read the db.
      then close everything db(s), env, ect ...

      well, any hints would be greatly appreciated

          You'll need to do a little more debugging and/or post the code that's doing the writing, serialization and deserialization.
