Null Pointers using OpenBaseMovil-db

Tim Corrigan — Thu, 24 Jan 2008 09:31:51 -0000

I've made this a support request rather than a bug because it seems I'm likely doing something obvious wrong.

I want to use OpenBaseMovil-db as I have a need to store and then find around 5,000 items. I wrote a simple test that created a database, added a table and inserted one row into it but I was getting NullPointerExceptions. So I whittled the code down to the simplest thing possible - just creating a database.

I have tried this on the Nokia Series 40 3rd Edition Emulator and Nokia Series 60 3rd Edition Emulator with the same results.

Any pointers appreciated

private void createDB() {
try {
System.out.println("About to create database");
Database.create( VIRTUAL_DATABASE_NAME );
}
catch(Exception e) {
e.printStackTrace();
}
}

Here is the output:

Row creation failes

Anonymous — Mon, 21 Jan 2008 14:07:44 -0000

This is the problematic code piece:

db = Database.create(db_name);
db = Database.connect(db_name);
db.start();
Table table = new Table(table_name);
table.addColumn("fname", Constants.FT_STRING, false);
db.createTable(table);
log("Table created");
worktable = db.getTable(table_name);
worktable.open();
log("Table '"+ worktable.getName() +"' in DB "+ worktable.getParent().getName() +" opened");
Row row = worktable.createRow();
log("Row created");
row.setField("fname", "someName");
log("Added "+row.getString("fname"));
log("Row filled");
row.save(); //HERE THE PROBLEM ARISES
log("Row saved");

The log goes until "Row filled", but when executing row.save(), the following error occurs:

java.lang.NullPointerException
at bm.db.Table.save(+120)
at bm.db.Row.save(+15)
at tests.BMDatabaseTest.doTest(+195)
at Tester.commandAction(+182)
at javax.microedition.lcdui.List.callKeyPressed(+80)
at javax.microedition.lcdui.Display$DisplayAccessor.keyEvent(+198)

at com.sun.midp.lcdui.AutomatedEventHandler.keyEvent(+210)
at com.sun.midp.lcdui.DefaultEventHandler$QueuedEventHandler.run(+178)

I hope this is not my fault, as I have created and started the DB and opened the table after retrieving it. Hope this is helpful for you, just wanted to help. Thanks
