I am working on a Phonegap application that uses an Android service to check for message updates while the app isn't being used. In order to do that, however, I need the session key generated by the user's username and password. The generation of the session key is handled on the Javascript/HTML side of things while the app is active in the foreground.
My question is, how do I access a Javascript variable for use in Java? I need the session key value as a String object in Java. I just need to access it once, and I don't have a clue how Javascript-to-Java communication works.
You can pass a javascript variable to the java while using the plugins as below.
cordova.exec(null, null, "service", "action", ["firstArgument", "secondArgument", 42]);
Here the first and second parameter to the exec method are the sucess and failure calllback.
service and action are the native class and method names respectively.
And the last parameter ["firstArgument", "secondArgument", 42] are the javascript variables which you can pass to the native method.
For more details please go through the following link.

Their is a requirement in a project to send emails from java application through lotus notes.
Note: the domino server is installed on client server.
Currently i am able to send email using notesFactory on my local machine.using notes.jar file
Which accesses the user by .nsf by its password.
I.e creating secure connection by password.
And gtting database object by calling
Session.getdatabase(null,"user.nsf")
Its perfectly working.
But for some types of emails the client have shared a generic id...(link) over an email... By clicking on that link the generic mail box opens under active user. In separate tab... Through which we can send emails.
But have not shared their .nsf path or id or password.
It directly opens by clicking on that link.
Now i want to access that generic id in notesfactory session
I tried to keep open that id and then running my code...but still it sends email through active user itself.
And client is not ready to share the id and password details of that user. Not the id file is getting generated in our local machine.
Is their any way to send emails through that id?
If anyone want code i am using..ill share.
But for some types of emails the client have shared a generic
id...(link) over an email... By clicking on that link the generic mail
box opens under active user. In separate tab... Through which we can
send emails.
That does not sound like a "shared id", it sounds more like a mail database with the ACL set to give a group of users access.
When you send an email from within Notes (no matter if it is through the UI or through code), the actual logged in user is used as the sender. It is intentionally by design, to prevent users from spoofing the sender.
There is an unsupported way to fake the sender address, by dropping the email directly into mail.box, but that should only be done by someone know what they are doing.
I wrote a script library several years ago, intended to help sending emails. It includes the ability to set the sender address. You can find it on my blog, it's free to use. But I would not recommend you using it without first understanding what the code is doing.
Here is the relevant part of the code:
Set mailbox = New NotesDatabase(mailservername,"mail.box")
If mailbox.Isopen = False Then
Print "mail.box on " & mailservername & " could not be opened"
Exit Sub
End If
Set me.maildoc = New NotesDocument(mailbox)
Call me.maildoc.ReplaceItemValue("Form","Memo")
Set me.body = New NotesRichTextItem(maildoc,"Body")
Call maildoc.ReplaceItemValue("Principal", me.p_principal)
' If principal is set, we want to fix so mail looks like
' it is coming from that address, need to set these fields
Call maildoc.ReplaceItemValue("From", me.p_principal)
Call maildoc.ReplaceItemValue("Sender", me.p_principal)
Call maildoc.ReplaceItemValue("ReplyTo", me.p_principal)
Call maildoc.ReplaceItemValue("SMTPOriginator", me.p_principal)
Call maildoc.ReplaceItemValue("PostedDate",Now())
If me.p_principal<>"" Then
Call maildoc.Save(True,False) ' Save in mail.box
Else
Call maildoc.Send(True) ' Send mail normally
End If
You use the Principal field to set the sender address.
I know that returning a value from a JWSapp to the "calling" page cannot be done.
However, I use this JWSapp to get user ID from its biometric information.
The idea is that when you try to login, a button allows to launch the JWSapp that will deal with the biometric tasks and then return the user's idea.
Still, as I said, from a JWSapp I cannot send back the id to auto-complete the field. I found this post: Returning a value from a java web start application but I really need to keep the JWS (external constraints)...
So there's my question: is there any workaround to get the id back?
Thank you in advance :)
I'll first say that I'm sure it is just me since people have probably got this to work out of the box without having to edit the ADAL 4 Android Library without editing the source.
When running the sample program and authenticating with a token I get an error from AZURE that it is not passing the client_secret in the message body. I can confirm that this is in fact the case - it is not passing the client_secret.
Although if I edit the OAuth2.java file and change the method buildTokenRequestMessage to something like the following the workflow works perfectly
public String buildTokenRequestMessage(String code) throws UnsupportedEncodingException {
String message = String.format("%s=%s&%s=%s&%s=%s&%s=%s&%s=%s",
AuthenticationConstants.OAuth2.GRANT_TYPE,
StringExtensions.URLFormEncode(AuthenticationConstants.OAuth2.AUTHORIZATION_CODE),
AuthenticationConstants.OAuth2.CODE, StringExtensions.URLFormEncode(code),
AuthenticationConstants.OAuth2.CLIENT_ID,
StringExtensions.URLFormEncode(mRequest.getClientId()),
AuthenticationConstants.OAuth2.REDIRECT_URI,
StringExtensions.URLFormEncode(mRequest.getRedirectUri())
// these are the two lines I've added to make it work
AuthenticationConstants.OAuth2.CLIENT_SECRET,
StringExtensions.URLFormEncode("<MY CLIENT SECRET>")
);
return message;
}
Am I doing something wrong? If not, what is the correct way to access the client secret?
My implementation is straight from the demo application with only changes being setting up the strings to match my endpoints.
Thanks
You need to register your app as a Native application at Azure AD portal. You don't need client secret for native app.
We are used MandrillApp in production server without autotesting. How to I can mocking mandriil api call for unit test, without real sending message?
In Mandrill, go to SMTP & API Credentials on your main menu.
Click "+ New API Key"
Give it a description (something like TEST KEY is good).
Check the "Test Key" check-box.
Click the "Create API Key" button.
You will create a new API key in your list. It's a ~22 digit key just like your main API key.
Use this key instead of your main API key in any test calls and the message(s) will not be sent.
To observe the simulated results in Mandrill, go to your account menu and turn on "Test Mode". You will then be able to see all the incoming test API calls.
So I have a java program running within an Amazon EC2 instance. Is there a way to programatically get its own tags? I have tried instantiating a new AmazonEC2Client to us the describeTags() function but it only gives me null. Any help would be appreciated thank you.
Edit: To make things clearer, the instances are going to be unmanned worker machines spun up to solely do some computations
This should help you get started...
String instanceId = EC2MetadataUtils.getInstanceId();
AmazonEC2 client = AmazonEC2ClientBuilder.standard()
.withCredentials(new DefaultAWSCredentialsProviderChain())
.build();
DescribeTagsRequest req = new DescribeTagsRequest()
.withFilters(new Filter("resource-id", Collections.singletonList(instanceId)));
DescribeTagsResult describeTagsResult = client.describeTags(req);
List<TagDescription> tags = describeTagsResult.getTags()
You should be able to get the current instance id by sending a request to: http://169.254.169.254/latest/meta-data/instance-id. This only works within ec2. With this you can access quite a bit of information about the instance. However, tags do not appear to be included.
You should be able to take the instance id along with the correct authentication to get the instance tags. If you are going to run this on an instance, you may want to provide an IAM user with limited access instead of a user which has access to everything in case the instance is compromised.
While using user-data may be the simplest solution, the OP was asking specifically about the tagging, and unfortunately amazon hasn't made this as easy as it could be. However, It can be done. You want to use a combination of 2 amazon services.
First you need to retrieve the Instance ID. This can be achieved by hitting the URL from within your instance:
http://169.254.169.254/latest/meta-data/instance-id
Once you have the resource ID, you'll want to use Amazon's EC2 API to access the tags. Since you said you're using Java, I would suggest the Using the AWS SDK amazon makes available. Within this SDK you'll find a method called describeTags (documentation). You can use a Resource ID as one of the filters to get the specific tags to your instance. Supported filters are
tag key
resource-id
resource-type
I suggest doing this retrieval at boot using something like cloud-init and caching the tags on your server for use later if necessary.
