Get Member details using Java in Microsoft Bot Framework SDK

I am currently working on delivering 1:1 messages to the users in Teams.
Problem Statement: I am having trouble trying to get the member details to populate the Channel Account to set the ConverstationParameters object to create conversation if the user is not part of a team. Is there a way I could get the details of the user without having the user part of a Team. I wasn't able to find any reference documentation to how to get this information for Java.
Below is my code snippet:
Setup credentials and initialize a connection using Connector Client.
Populate Channel account with recipient details for set members on Conversation Parameters Object.
Activity message = MessageFactory.text("Hello World");
MicrosoftAppCredentials credentials = new MicrosoftAppCredentials(appClientID, appClientSecret);
try (ConnectorClient client = new RestConnectorClient(serviceUrl, credentials)) {
logger.info("** Connector Client Set: {} **", client);
ConversationParameters conversationParameters = new ConversationParameters();
conversationParameters.setIsGroup(false);
CompletableFuture<ChannelAccount> user = ((Conversations) client.getConversations())
.getConversationMember(recipient, teamsInternalId); // Don't want to use this because the user has to be part of the same team which is not true in our case.
logger.info("** Aysnc get User details call **");
logger.info("** AAID: {} **", user.get().getAadObjectId());
try {
conversationParameters.setMembers(Collections.singletonList(user.get()));
} catch (ErrorResponseException e) {
logger.error("** User Error : {}**", e.getMessage());
}
conversationParameters.setTenantId(tenantId);
TenantInfo tenantInfo = new TenantInfo(tenantId);
TeamsChannelData channelData = new TeamsChannelData();
channelData.setTenant(tenantInfo);
conversationParameters.setChannelData(channelData);
CompletableFuture<ConversationResourceResponse> conversationResourceResponse = new CompletableFuture<ConversationResourceResponse>();
try {
conversationResourceResponse = client.getConversations()
.createConversation(conversationParameters);
logger.info("** Create Conversation: {} **", conversationResourceResponse.get().getId());
} catch (ErrorResponseException e) {
logger.error("** Create Conversation : {} **", e.getMessage());
}
CompletableFuture<ResourceResponse> response = client.getConversations()
.sendToConversation(conversationResourceResponse.get().getId(), message);
logger.info("** Send Conversation **", response.get().getId());

I solved the above requirement following these steps:
Check if my app is installed for the user using Graph API.
If not installed, force install the app for the user using Graph API.
Then retrieve the conversation chat id.
Use this chat id to send the message to the user.
There steps are outline here on the MSFT reference page:
https://learn.microsoft.com/en-us/microsoftteams/platform/graph-api/proactive-bots-and-messages/graph-proactive-bots-and-messages?tabs=dotnet
I hope this answer helps anyone in the same boat who would like to send messages directly 1:1 from an app to a Teams user without any mutual Team condition.

Microsoft Azure Table Storage: CloudTable() error no suggestions available

I'm using the Azure table storage from java, following the tutorial here. I'm successfully able to create a table, add an entity, retrieve an entity and delete an entity. However, I've got this method to delete a table:
public void deleteTable(String tableName) {
try {
CloudStorageAccount storageAccount = CloudStorageAccount.parse(storageConnectionString);
CloudTableClient tableClient = storageAccount.createCloudTableClient();
// Delete the table and all its data if it exists.
CloudTable cloudTable = new CloudTable(tableName, tableClient);
cloudTable.deleteIfExists();
} catch (Exception e) {
System.out.println("Error in deleting");
e.printStackTrace();
}
}
In this method I am getting an error on this line
CloudTable cloudTable = new CloudTable(tableName, tableClient);
which has no suggestions available within eclipse only the following markers:
Multiple markers at this line
The constructor CloudTable(String, CloudTableClient) is not visible
The constructor CloudTable(String, CloudTableClient) is not visible
Any help would be greatly appreciated.

If you look at CloudTable constructors here, you will notice that the code you're using is not a valid one. It is possible that the SDK got upgraded however the code sample isn't. I would suggest using getTableReference method on CloudTableClient to get an instance of CloudTable:
try
{
// Retrieve storage account from connection-string.
CloudStorageAccount storageAccount =
CloudStorageAccount.parse(storageConnectionString);
// Create the table client.
CloudTableClient tableClient = storageAccount.createCloudTableClient();
// Delete the table and all its data if it exists.
CloudTable cloudTable = tableClient.getTableReference("people");
cloudTable.deleteIfExists();
}
catch (Exception e)
{
// Output the stack trace.
e.printStackTrace();
}

Limit web service access to only one app

Right now I am working on a android app and I am totally new to this.
I want to make sure my web-service is only accessible via my app.
My background is PHP. In PHP I don't need to worry about anything like that, because everything runs on a server.
In case of Java and especially Android programming things are different. Even with encryption. Everybody can just open an APK and see how the web service gets accessed. So is there a way to hide or to obfuscate the access to a web service, so only my app will be able to use it?
For test purposes I didn't add any security or encryption. This is the basic call to a web server I am doing right now:
String url = "http://thisismyurl.com/a.php?action=get";
String result = Web.executeWeb(url);
public class Web {
public static String executeWeb(final String url) {
final StringBuilder sb = new StringBuilder();
Thread thread = new Thread(new Runnable() {
public void run()
{
try
{
InputStream is = (InputStream) new URL(url).getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
String result, line = reader.readLine();
result = line;
while((line=reader.readLine())!=null){
result+=line;
}
sb.append(result);
//System.out.println(result);
//Log.i("My Response :: ", result);
} catch (Exception e)
{
// TODO: handle exception
}
}
});
thread.start();
try {
thread.join();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return sb.toString();
}
}
How would I hide this from the prying eyes of hackers? ;-) Is that even possible?
Thanks in advance!

Deploy client authentication using (self signed) certificates within TLS.
This kind of configuration can be enabled on most web servers and Java application servers, and you can normally also configure the web or application server in such a way that you can retrieve the certificate of the private key that the client used to authenticate itself.
Note that HTTPS uses SSL (or now TLS) before any web trafic, so you cannot program this in your application, it does require server configuration.
Check this link on how to configure for Apache 2.

Use your Application's ID ( like IMEI ) as parameter in your webservice call. You need to make a table in database at server side which will store all registered device. Now only these registered device can access your webservice. This is my idea, there should be other idea as well.

Google App Engine HTTP ERROR 503 error

Ï am Taking data From server written in "C" using Sockets .
My java class name is ReceivingData, and here's the code for receiving the data and storing it in ArrayList and passing the ArrayList to other Class's Constructor.
package pack.exp;
import java.io.InputStream;
import java.net.Socket;
import java.util.ArrayList;
import java.util.List;
public class ReceivingData implements Runnable
{
public static void main(String[] args)
{
Thread t = new Thread(new ReceivingData());
t.start();
}
public List<String> obj1;
#Override
public void run()
{
Socket s;
InputStream stream;
try
{
s = new Socket("10.9.211.22", 6870);
stream = s.getInputStream();
byte[] data = new byte[13];
int read;
String can_Id= null;
while((read = stream.read(data)) != -1)
{
String can_Data=
String.format("%02X:%02X:%02X:%02X,
data[0], data[1], data[2], data[3]);
List<String> obj1= new ArrayList<String>();
obj1.add(can_Data.substring(0, 2));
obj1.add(can_Data.substring(3, 5));
obj1.add(can_Data.substring(6, 8));
obj1.add(can_Data.substring(9, 11));
Receiving_At_Regular_IntervalServlet rari= new
Receiving_At_Regular_IntervalServlet(obj1);
Thread.sleep(3000);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
This is the Servlet which is receiving the data from ArrayList passed by the above File.
and storing this data from the arraylist in to the Entity for datastore and deploys it on the Google App engine.
package pack.exp;
#SuppressWarnings("serial")
public class Receiving_At_Regular_IntervalServlet extends HttpServlet
{
List<String> obj2= new ArrayList<String>();
public Receiving_At_Regular_IntervalServlet(List<String> obj2) throws
IOException
{
this.obj2= obj2;
System.out.println("Receiving in Web Project" + obj2);
System.out.println("");
System.out.println("");
}
public void doGet(HttpServletRequest req, HttpServletResponse resp) throws
IOException
{
Key k1 = KeyFactory.createKey("C","0D F0 0800 1");
String parameter1 = obj2.get(0);
Entity can1 = new Entity(k1);
can1.setProperty("First Parameter", parameter1);
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
datastore.put(can1);
Entity can11 = null;
try
{
can11= datastore.get(k1);
}
catch (EntityNotFoundException e)
{
e.printStackTrace();
}
String first_P= (String) can11.getProperty("First Parameter");
resp.setContentType("text/plain");
resp.getWriter().println("Parameter--- " + first_P);
}
}

The ReceivingData code evidently runs a thread and reads data from 10.9.211.22 port 6870 using Socket from a local computer. That's fine. It converts four bytes to a List and passes that to Receiving_At_Regular_IntervalServlet. Fine but not what you need.
This part might work on a development computer but won't work if deployed to the cloud. AppEngine servers does not permit developers to define main(), use Socket or communicate with private IP subnet 10. Forget about deploying that code to AppEngine.
Receiving_At_Regular_IntervalServlet has a custom constructor. AppEngine does not call your constructor because its servlet code expects only the default constructor. That is probably when your 503 error occurs.
With servlets the data is not supposed to come in via a constructor. Data must come in via members of the request parameter of the doGet method (though to be RESTful you should rather use doPut in this example). You insert the data into the request parameter but sending a correctly constructed http request to the server. Your code lacks that web application design.
Build your main program and your AppEngine code in separate projects and make main talk to servlet using http.

HTTP ERROR 503 error
You can't help anything when a server throws this error. It is only thrown when a service from the server is unavailable.
You need explicit handling on such error codes, other than 200 OK, in the client app and appropriate message has to be shown or as the alternate requirement suggestion.

XMLRPC IP.Board could not locate an API module called

I have a case: make work with forum by API fo Forum Engine IP.Board.
So i wrote next code:
package ru.test;
import java.net.MalformedURLException;
import java.net.URL;
import org.apache.xmlrpc.XmlRpcException;
import org.apache.xmlrpc.client.XmlRpcClient;
import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;
public class mainClass {
/**

*/
public static void main(String[] args) {
XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
try {
config.setServerURL(new URL("http://hbf.by/interface/board/index.php"));
XmlRpcClient client = new XmlRpcClient();
client.setConfig(config);
Object[] params = new Object[]{"74600b7376c4b1db69eaf8f155f2d157", "ipb","','"};
Object result = client.execute("fetchOnlineUsers", params);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlRpcException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
But i get exception

What's wrong?
In Documentation (http://community.invisionpower.com/resources/documentation/index.html/_/developer-resources/miscellaneous-articles/xml-rpc-api-r246) sayed:
You should submit XML-RPC calls to the interface/board/index.php file.
You should send all parameters as a struct.
Every request must submit two parameters: api_key - this should be
the key set up earlier. api_module - this should be "ipb".
Theoretically, you can create other modules, but "ipb" is all that
ships with IP.Board.
Where i make mistake.
And also how i can get methods.php file?
I write URL http://hbf.by/interface/board/modules/ipb/methods.php
But get blank page.
But also in Documentation sayed:
Open the interface/board/modules/ipb/methods.php file to see which
parameters each method expects to receive and will send back in
response
May be some server need configurations, but in internet i can't find it.

Your code does seem to match the documentation.
But, XMLRPC often specifies the module in the call like this
Object result = client.execute("ipb.fetchOnlineUsers", params);
You could try that.

I found where is trouble
don't use Object[] params = new Object[]{"74600b5f2d157", "ipb","','"};
instead use
HashMap and then
Object result = client.execute("ipb.fetchOnlineUsers",new Object[] {hMap});
It's work correctly
