When i add jar6 library it does n't show any error but i got packing failed.
I need to import these files.
can any one please post how can i import these files.
Thank u in advance.
BlackBerry uses J2ME which is Java 1.3. You won't be able to use Java 6 classes. Instead you should look at the BlackBerry API. It has classes for encryption but you'll need to rewrite your code to use them.

I'm using for the first time awsglueml package to use the class FillMissingValues. I'm using Glue 3.0 importing the ML package as mentionned by the documentation:
from awsglueml.transforms import FillMissingValues
...
dyf = FillMissingValues.apply(dyf, "demographic", output_column="demographic")
And I got an import error:
from awsglueml.transforms import FillMissingValues
ImportError: cannot import name 'FillMissingValues' from 'awsglueml.transforms' (/opt/amazon/lib/python3.6/site-packages/awsglueml/transforms/__init__.py)
Why does the latest Glue version is not up-to-date with the latest documentation? FillMissingValues should be in the awsglueml/transform package.
I import a package and would forward a member of it. What syntax does Dart offer for that?
foo.dart
import 'package:xzy/xzy.dart'; // contains class Xyz
// how do I forward Xyz here to make it available in bar.dart?
bar.dart
import 'package:mypackage/foo.dart';
Xyz is hidden here
You can use export
import 'package:xzy/xzy.dart';
export 'package:xzy/xzy.dart' show Xyz;
or just
export 'package:xzy/xzy.dart' show Xyz;
You don't need to import for that. Just export is enough if you don't need Xyz in this re-exporting file.

What is the difference between "show" and "as" in an import statement?
Ex.
Files:
1.dart
2.dart
3.dart
2.dart:
import 'package:packagename/3.dart';
1.dart
import 'package:packagename/2.dart';
Does 1.dart import 3.dart?
When you import a file you import
everything public declared in the imported file
everything public declared in part files of the imported file
everything explicitly exported from the imported file
If it is not explicitly exported in it won't be imported transitively.
1.dart does not import 3.dart in your example.
If 2.dart would contain
export 'package:packagename/3.dart';
then 1.dart would also import 3.dart
I tried to use the router in angular2-beta.20 in Dart with the HashLocationStrategy.
But I couldn't find any docs, except for
this link to angular2-beta.15 docs, which are incomplete.
The example shows TypeScript imports instead of Dart ones.
So I tried to import package:angular2/router.dart, but the Dart Analyzer keeps complaining that it can not find LocationStrategy and HashLocationStrategy
Also I don't know, how to write the import exactly, because a top-level provide function, as in the example above, seems non existent.
provide(LocationStrategy, {useClass: HashLocationStrategy})
After some research I found the following:
LocationStrategy and HashLocationStrategy are now part of
package:angular2/platform/common.dart instead of package:angular2/router.dart.
The bootstrap()- method is platform specific, so we need to import package:angular2/platform/browser.dart.
We need to import package:angular2/router.dart to have ROUTER_PROVIDERS available in bootstrap() method.
Here is a working code example for the dart file initializing :
// needed to import "bootstrap" method
import 'package:angular2/platform/browser.dart';
// needed to import LocationStrategy and HashLocationStrategy
import 'package:angular2/platform/common.dart';
// needed for Provider class
import 'package:angular2/angular2.dart';
// needed to import ROUTER_PROVIDERS
import 'package:angular2/router.dart';
// import your app_component as root component for angular2
import 'app_component.dart';
void main() {
bootstrap(AppComponent, [
ROUTER_PROVIDERS,
const Provider(LocationStrategy, useClass: HashLocationStrategy)
]);
}
Hope this helps somebody! :)
Below are my imports used in my java program. What I am trying to do is, to create a client of type MqttCient and then use the method connectWithResuls as follows
client.connectWithResult(opts);
the problem is eclipse underscores the lie mentioned above with red squiggle, and I do not know why, I also referred to Paho java docs here.
please let me know why the aforementioned method is not recognised.
