How to start CloudFoundry app using ReactorCloudFoundryClient?

I used StartApplicationRequest to create a sample request to start the application as given below:
StartApplicationRequest request = StartApplicationRequest.builder()
.applicationId("test-app-name")
.build();
Then, I used the ReactorCloudFoundryClient to start the application as shown below:
cloudFoundryClient.applicationsV3().start(request);
But my test application test-app-name is not getting started. I'm using latest Java CF client version (v4.5.0 RELEASE), but not seeing a way around to start the application.
Quite surprisingly, the outdated version seems to be working with the below code:
cfstatus = cfClient.startApplication("test-app-name"); //start app
cfstatus = cfClient.stopApplication("test-app-name"); //stop app
cfstatus = cfClient.restartApplication("test-app-name"); //stop app
I want to do the same with latest CF client library, but I don't see any useful reference. I referred to test cases written at CloudFoundry official Github repo. I derived to the below code after checking out a lot of docs:
StartApplicationRequest request = StartApplicationRequest.builder()
.applicationId("test-app-name")
.build();
cloudFoundryClient.applicationsV3().start(request);
Note that cloudFoundryClient is ReactorCloudFoundryClient instance as the latest library doesn't support the client class used with outdated code. I would like to do all operations (start/stop/restart) with latest library. The above code isn't working.

A couple things here...
Using the reactor based client, your call to cloudFoundryClient.applicationsV3().start(request) returns a Mono<StartApplicationResponse>. That's not the actual response, it's the possibility of one. You need to do something to get the response. See here for more details.
If you would like similar behavior to the original cf-java-client, you can call .block() on the Mono<StartApplicationResponse> and it will wait and turn into a response.
Ex:
client.applicationsV3()
.start(StartApplicationRequest.builder()
.applicationId("test-app-name")
.build())
.block()
The second thing is that it's .applicationId not applicationName. You need to pass in an application guid, not the name. As it is, you're going to get a 404 saying the application doesn't exist. You can use the client to fetch the guid, or you can use CloudFoundryOperations instead (see #3).
The CloudFoundryOperations interface is a higher-level API. It's easier to use, in general, and supports things like starting an app based on the name instead of the guid.
Ex:
ops.applications()
.start(StartApplicationRequest.builder()
.name("test-app-name").build())
.block();

Hyperledger fabric endorsement policy error using Java SDK

I am working on golang version of fabcar smart contract while seeking to implement a Java-SDK API which enrolls an admin, registers a user and performs query-update value operations based on https://github.com/hyperledger/fabric-samples/tree/master/fabcar/java
I have successfully set up a 3 org-9 peers blockchain network, installed, instantiated and invoked chaincode on peers.
However, as i am working on implementing the relative API, i am only able to successfully query blockchain database, while getting a "Could not meet endorsement policy for chaincode mycc"
Please find below screenshot of relative error
Endorsement policy is "OR ('Org1MSP.member','Org2MSP.member', 'Org3MSP.member')".
Should registered user somehow get an Org1/Org2/Org3.member attribute? Any leads would be appreciated!

Like #Ikar Pohorský said, for me this got resolved after I used correct method name. Also, ensure that you delete 'wallet' folder in order to regenerate the user if your HLF n/w was recreated.
#Test
public void testMyMethodToBeInvoked() throws Exception {
deleteDirectory(".\\wallet");
EnrollAdmin.main(null);
RegisterUser.main(null);
// Load a file system based wallet for managing identities.
final Path walletPath = Paths.get("wallet");
final Wallet wallet = Wallet.createFileSystemWallet(walletPath);
// load a CCP
final Path networkConfigPath = Paths
.get("C:\\sw\\hlf146-2\\fabric-samples\\first-network\\connection-org1.yaml");
final Gateway.Builder builder = Gateway.createBuilder();
builder.identity(wallet, "user1").networkConfig(networkConfigPath).discovery(true);
// create a gateway connection
try (Gateway gateway = builder.connect()) {
final Network network = gateway.getNetwork("mychannel");
final Contract contract = network.getContract("mycc");
String myJSONString="{\"a\":\"b\"}";
byte[] result;
// Following did NOT work. Control goes directly to 'invoke' when 'submitTransaction' is done directly. 'invoke' need not be mentioned here.
// result = contract.submitTransaction("invoke", myJSONString);
// Following DID work. In chaincode (my chain code was Java) I had a method named 'myMethodToBeInvoked'. The chain code was written similar to https://github.com/hyperledger/fabric-samples/blob/release-1.4/chaincode/chaincode_example02/java/src/main/java/org/hyperledger/fabric/example/SimpleChaincode.java
result = contract.submitTransaction("myMethodToBeInvoked", my);
System.out.println(new String(result));
}
}
EDIT: Also, please remember that if your chaincode throws errorResponse, even then we can have this endorsement fail issue. So, check if your chain code is working without any issues.

Atlassian Confluence communication/authentication between plugins

I'm (new at this) developing a macro plugin that builds on data that an existing plugin provides via its REST API. They would run on the same instance of Confluence, version 5.9.
I cannot use the Java API of the plugin, since it only provides access to a very limited amount of classes, so I decided on using Rest.
Given that the user has already authenticated with Confluence, is there any way to communicate my current user credentials from my plugins Java Rest client to the other one, preferably not using Basic Authentication?
So far, I've tried:
Shared Access Layer - this apparently used to work with the method Request#addTrustedTokenAuthentication() but is deprecated in SAL 3.0.5,
see SAL Documentation (outdated?), and SAL Version Matrix
ApplicationLink - would allow me to link to another application, but apparently it's not possible to link back to the same Confluence instance
SAL TrustedRequestFactory- comments on this atlassian answer indicate there might be a way using this, but I can't seem to figure it out (yet).
I've also tried reading up on atlassian documentation and posted a similar question on atlassian answers here. I don't mean to double post, but unfortunately, looking at other questions on that platform, few seem to get answered in a timely fashion so I thought I'd try my luck here.

Seems like this isn't a very common problem, but I thought I'd post how we eventually solved this, just in case it's needed again:
#Component
public class RestClient {
#ComponentImport
private TrustedTokenFactory tokenFactory;
// [...]
public String doRequest(HttpClient client, String url) throws Exception {
TrustedTokenAuthenticator auth =
new TrustedTokenAuthenticator(tokenFactory);
HttpMethod method = auth.makeMethod(client, url);
try {
// add request headers, etc...
int statusCode = client.executeMethod(method);
// be sure to use response data here, catch exceptions...
} finally {
method.releaseConnection();
}
}
}

Adding API method to App Engine causes NullPointerException

I'm using the local App Engine and I have a working Endpoint, but when I add the following API, the API Explorer (https://developers.google.com/apis-explorer/?base=http://localhost:8888/_ah/api#p/) doesn't load while the JavaScript console has an unhandled exception.
#ApiMethod(name = "getClientByPublicId")
public Client getClientByPublicId(#Named("publicId") String publicId) {
EntityManager mgr = getEntityManager();
Client client = null;
client = mgr.find(Client.class, publicId);
mgr.close();
return client;
}
Within the Chrome JavaScript console, it doesn't give anything useful because it's minimized
Uncaught java.lang.NullPointerException
(anonymous function)
(anonymous function)
h
(anonymous function)
F.(anonymous function).z.(anonymous function).z.(anonymous function)
_.T.K.__cb
h
c
The whole API Explorer page comes up blank.
I've ran this in debug mode and set a breakpoint within the added API, but it isn't triggered.
If I load the discovery document at http://localhost:8888/_ah/api/discovery/v1/apis/clientendpoint/v1/rest, it fails with the following response.
{
"error" : {
"message" : ""
}
}
If I remove this new API it all works fine, albeit without having the new API.
Anyone know what is causing this?
Update
I stumbled across Google APis Explorer didn't found my available ApiMethod from my app-engine app and it sounds like there may be a path collision, which I don't understand yet but I'm going to try to work on this idea now.
If this may be the issue, the related API is
#ApiMethod(name = "getClient")
public Client getClient(#Named("id") Long id) {
EntityManager mgr = getEntityManager();
Client client = null;
try {
client = mgr.find(Client.class, id);
} finally {
mgr.close();
}
return client;
}
I'll give this a shot and answer my question, unless someone knows different.

After finding Google APis Explorer didn't found my available ApiMethod from my app-engine app I learned that you must include a new path.
For example, I was able to alter the ApiMethod to
#ApiMethod(
name = "getClientByPublicId",
path = "client/publicId/{publicId}",
httpMethod = "GET"
)
Works great now.

How to configure a Two-legged Spring-OAuth provider/client?

Im working on oauth 1 Sparklr and Tonr sample apps and I'm trying to create a two-legged call. Hipoteticly the only thing you're supposed to do is change the Consumer Details Service from (Im ommiting the igoogle consumer info to simplify):
<oauth:consumer-details-service id="consumerDetails">
<oauth:consumer name="Tonr.com" key="tonr-consumer-key" secret="SHHHHH!!!!!!!!!!"
resourceName="Your Photos" resourceDescription="Your photos that you have uploaded to sparklr.com."/>
</oauth:consumer-details-service>
to:
<oauth:consumer-details-service id="consumerDetails">
<oauth:consumer name="Tonr.com" key="tonr-consumer-key" secret="SHHHHH!!!!!!!!!!"
resourceName="Your Photos" resourceDescription="Your photos that you have uploaded to sparklr.com."
requiredToObtainAuthenticatedToken="false" authorities="ROLE_CONSUMER"/>
</oauth:consumer-details-service>
That's adding requiredToObtainAuthenticatedToken and authorities which will cause the consumer to be trusted and therefore all the validation process is skipped.
However I still get the login and confirmation screen from the Sparklr app. The current state of the official documentation is pretty precarious considering that the project is being absorbed by Spring so its filled up with broken links and ambiguous instructions. As far as I've understood, no changes are required on the client code so I'm basically running out of ideas. I have found people actually claiming that Spring-Oauth clients doesn't support 2-legged access (which I found hard to believe)
The only way I have found to do it was by creating my own ConsumerSupport:
private OAuthConsumerSupport createConsumerSupport() {
CoreOAuthConsumerSupport consumerSupport = new CoreOAuthConsumerSupport();
consumerSupport.setStreamHandlerFactory(new DefaultOAuthURLStreamHandlerFactory());
consumerSupport.setProtectedResourceDetailsService(new ProtectedResourceDetailsService() {
public ProtectedResourceDetails loadProtectedResourceDetailsById(
String id) throws IllegalArgumentException {
SignatureSecret secret = new SharedConsumerSecret(
CONSUMER_SECRET);
BaseProtectedResourceDetails result = new BaseProtectedResourceDetails();
result.setConsumerKey(CONSUMER_KEY);
result.setSharedSecret(secret);
result.setSignatureMethod(SIGNATURE_METHOD);
result.setUse10a(true);
result.setRequestTokenURL(SERVER_URL_OAUTH_REQUEST);
result.setAccessTokenURL(SERVER_URL_OAUTH_ACCESS);
return result;
}
});
return consumerSupport;
}
and then reading the protected resource:
consumerSupport.readProtectedResource(url, accessToken, "GET");
Has someone actually managed to make this work without boiler-plate code?
