I am new to apache camel. What I am trying to do is I have exposed and Rest api to get data.
From that I need to communicate to an existing TCP server(Simple java server application) to retrieve data and send back to a client. What I have picked is Apache camel to do this integration.
rest()
.consumes("application/json").produces("application/json")
.get("/weather2/{city}").outType(WeatherDto.class).to("direct:get-weather-data")
from("direct:get-weather-data")
.process(this::setTCPMsg)
.to("netty://tcp://127.0.0.1:9898")
Above is the way I have defined the routes but when I try to run the appication I get below eror
org.apache.camel.FailedToCreateRouteException: Failed to create route route5 at: >>> To[netty://tcp://127.0.0.1:9898] <<< in route: Route(route5)[From[direct:get-weather-data] -> [process[Proc... because of No endpoint could be found for: netty://tcp://127.0.0.1:9898, please check your classpath contains the needed Camel component jar.
Please advice How to solve this issue.

I'm trying to setup the mTLS authentication process for an endpoint created in the SICF transaction on ABAP-based software. I'm not using SAP HANA.
I've already imported the certificates into the STRUST transaction (SSL server Standard),
Inside the service on SICF, I've put the following settings in Logon Data tab:
But when I receive the HTTP request, the connection is returning the 401 status code.
Is that the right way to achieve this goal? If not, is there any documentation, where I can find a step by step on how to configure this type of authetication?
How can I connect airflow to a service that is accessible through an api gateway? I cant figure out how create airflow connection and add the path to the service on the gateway's address.
When creating a new connection in airflow admins tab, there are fields for ports, hostname and extra params.
Extra params work as a json in where you add extra parameters to the connection string.
Example:
Extra:
{
"param1": "val1",
"param2": "val2"
}
the conn url ends looking like:
my-conn-type://login:password#<hostname>:<port>/param1=val1¶m2=val2
In my case I am trying to acces to a livy server that is behind a apache knox api gateway, so the url for accesing the service looks like this:
https ://login:password#hostname:8444/gateway/cdp-proxy-api/livy
Cant either find documentation for this in airflow's docs
(probably its a newbie question, sorry)
Thanks!
We are running a simple application that connects to Firebase are reads some data. It fails to connect with the following timeout error:
#firebase/database: FIREBASE WARNING: {"code":"app/invalid-credential",
"message":"Credential implementation provided to initializeApp()
via the \"credential\" property failed to fetch a valid Google OAuth2 access token
with the following error: \"Failed to parse access token response: Error: Error
while making request: connect ETIMEDOUT
We are behind Firewall / Proxy and it appears that is blocking traffic to/from Firebase and hence failed connection. My question is what ports need to be opened and to what destination URLs to make this application work normally?
Any help will be much appreciated!
Finally, after struggling with the issue for several days got it working. Needed to contact network team and request to perform following actions:
Open ports 5228, 5229, 5230 for Firebase communication.
Opened communication at proxy level between the source server and following URLs:
fcm.googleapis.com
gcm-http.googleapis.com
accounts.google.com
{project-name}.firebaseio.com
Added following code in my node.js application:
var globalTunnel = require('global-tunnel-ng');
globalTunnel.initialize({
host: '<proxy-url>',
port: <proxy-port>,
//proxyAuth: 'userId:password', // optional authentication
sockets: 50 // optional pool size for each http and https
});
Installed module global-tunnel-ng:
npm install global-tunnel-ng
It solved the my problem and I hope it can help others too. :-)
I used Wireshark to monitor a local install of a Node.js application using the Admin SDK for firestore. I also referenced this list by Netify. This is what I found:
*.firebaseio.com
*.google.com
*.google-analytics.com
*.googleapis.com
*.firebase.com
*.firebaseapp.com
I decided to build a web service(app) for Apache Spark with Apache Livy.
Livy server is up and running on localhost port 8998 according to Livy configuration defaults.
My test program is a sample application in Apache Livy documentation: https://livy.incubator.apache.org/docs/latest/programmatic-api.html
While creating LivyClient by LivyClientBuilder class,
client = new LivyClientBuilder().setURI(new
URI("http","user:info","localhost",8998,"","",""))
.build();
I got "URI is not supported by any registered client factories" exception:
Exception in thread "main" java.lang.IllegalArgumentException: URI 'http://%5Bredacted%5D#localhost:8998?#' is not supported by any registered client factories.
at org.apache.livy.LivyClientBuilder.build(LivyClientBuilder.java:155)
at Client.<init>(Client.java:17)
at Client.main(Client.java:25)
I found out client instance stays null in LivyClientBuilder class.
client = factory.createClient(uri, this.config);
factory is an instance of LivyClientFactory interface.
The only class which implements the interface is RSCClientFactory.
In RSCClientFactory we have this piece of code:
if (!"rsc".equals(uri.getScheme())) {
return null;
}
I've tried "rsc" instead of "http", this is the error:
2018-09-15 11:32:55 ERROR RSCClient:340 - RPC error.
java.util.concurrent.ExecutionException: javax.security.sasl.SaslException: Client closed before SASL negotiation finished.

Apache Livy is running on http://localhost:8998 then I think we need submit our jar file to this address, but I don't understand "rsc" there.
I would appreciate if anyone guides me about these problems.
You just need to pass your URL as a String:
LivyClient client = new LivyClientBuilder()
.setURI(new URI("http://localhost:8998"))
.build();
After that you can add your *.jar file with:
client.addJar("file://...yourPathToJarHere.../*.jar");
or
client.uploadJar(new File("...."));
It depends on your cluster configuration. You can find full java API description here: https://livy.incubator.apache.org/docs/latest/api/java/index.html
The only class which implements the interface is RSCClientFactory.
Just add livy-client-http to your classpath.

We are trying to deploy an EAR on WebSphere Liberty.
Our application contains an EJB-module, which contains and EJB that makes a call to another SOAP server.
The WSDL of the service defines a wsp:Policy with ExactlyOne of http:BasicAuthentication xmlns:http="http://schemas.microsoft.com/ws/06/2004/policy/http"/
After deployment when we send a request to our application, which would trigger that SOAP-call we get an error: None of the policy alternatives can be satisfied.
I found some java-code on how to solve this
HTTPConduit http = (HTTPConduit) client.getConduit();
http.getAuthorization().setUserName("user");
http.getAuthorization().setPassword("pass");
But I do not want to do this in the Java-code but I want to make it part of the server config.
I found several helpful links, but still could not get it working.
Does anybody have any suggestions on how I can set this up?

You could use the JNDI feature to express the userid and password in server.xml, then have your java code pull it out of JNDI.
