I want to use JWT for generate token code in my Red5 server application.When I generate token code by JWT on local ,there is no mistake. When I embed my generate token code in Red5 server application,that show exception as follow:
[ERROR] [RTMPConnectionExecutor-1] org.red5.server.net.rtmp.BaseRTMPHandler - Exception

My code is like this:
public class Application extends MultiThreadedApplicationAdapter {
#Override
public boolean connect(IConnection conn, IScope scope, Object[] params) {
String token="eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9";
PayLoadMapper userValid = JWTUtil.unsign(token, PayLoadMapper.class);
System.out.println(userValid);
}
}
Why I can not embed my api code into Red5 application? It's the way which I do this make mistake.How I can do this?
Ensure Check the JWT lib exsited under you app.
I solve the problem. Ip put the jar in red5 server lib ,my appliction's lib is empty,so I put the JWT lib under the appliction.That's OK now.

I have an apache geode setup where there is one locator and one Server. we have a region employee in that. we were trying to implement in-line cache where a cache miss will lookup into database and will fill apache geode, but after deployment of Jars when i am trying to alter the region . It shows exception

Things tried
I tried by not implementing Declarable but still no success.
I have not done any change for serializer.
I've just tried the scenario using Apache Geode 1.13.2 and it works just fine, you can find the example here. Do you have multiple versions of the same jar within the server's class path?, that might be the reason for the exception.
Cheers.
I am using velocity as Java Code Generator, I am running a Eclipse application which has multiple plugins and different plugins are calling Velocity module for code generation.
Whenever i run a particular plugin it works fine individually no matter how many times i run it , Now if i will try to run the other plugin it throws velocity exception(i have provided stack trace below), I will restart the eclipse again and other plugin will work fine.
Conclusion: Velocity initialization fails when one plugin runs after some plugin already executed
The code i was using
velocityEngine = new VelocityEngine();
velocityEngine.setProperty(RuntimeConstants.RESOURCE_LOADER, LOCATION);
velocityEngine.setProperty(RESOURCE_LOADER,ClasspathResourceLoader.class.getName());
try {
velocityEngine.init();
} catch (Exception e) {
LOG.error("Failed to load velocity templates e={}", e);
}
i read it is caused by not able to create velocity.log file , then i tried it like this
velocityEngine = new VelocityEngine();
velocityEngine.setProperty(RuntimeConstants.RESOURCE_LOADER, "class,file");
velocityEngine.setProperty(RuntimeConstants.RUNTIME_LOG_LOGSYSTEM_CLASS, "org.apache.velocity.runtime.log.Log4JLogChute");
velocityEngine.setProperty("runtime.log.logsystem.log4j.logger", "VELLOGGER");
velocityEngine.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
velocityEngine.setProperty("runtime.log.logsystem.class", "org.apache.velocity.runtime.log.NullLogSystem");
/*
velocityEngine.setProperty(RuntimeConstants.RESOURCE_LOADER, LOCATION);
velocityEngine.setProperty(RESOURCE_LOADER,ClasspathResourceLoader.class.getName());
*/
try{
LOG.debug("Velocity Initialisation In AbstractFactory");
velocityEngine.init();
LOG.debug("Velocity Initialisation Done!!!");
}catch(Exception e){
LOG.error("Error Occured In Initialising Velocity Engine {}",e);
}
still it is failing while getting
template = velocityEngine.getTemplate(COMMAND_TEMPLATE_LOCATION.concat(command).concat(TEMPLATE_EXTENSION));
with exception stack trace:

Later i have found the actual root cause of the problem. It was whenever a plugin was initialising the velocity the other plugin was not able to re-initialise it, As the run time environment was same. Additionally both were present as separate module and hence it was not able to access it because of scope issue and hence velocity initialisation was failing.
The solution we implemented as we clubbed both the plugins under single module and hence initialised class from one module was accessible by other.
In my case veolocity and my application was initialized by 2 different class loaders. So when it tries to find the logger class in runtime it cannot find the class. As a solution I had to switched class loaders as a work around(anyway this is not a good way to solve this ).
VelocityEngine ve = new VelocityEngine();
Thread currentThread = Thread.currentThread();
ClassLoader temp = Thread.currentThread().getContextClassLoader();
try
{
currentThread.setContextClassLoader( getClass().getClassLoader() );
ve.setProperty( "runtime.log.logsystem.class", NullLogChute.class.getName() );
ve.init();
}
finally
{
currentThread.setContextClassLoader( temp );
}

It said:
ComputeEngineCredentials cannot find the metadata server. This is likely because code is not running on Google Compute Engine.
So does it mean that this code can run only inside Compute Engine?
Is there a way to connect to it from my local computer? Does anyone have any examples of this?
For running locally, you need to make sure that the environment variable GOOGLE_APPLICATION_CREDENTIALS is set to your key.json you got from cloud console. This is the likely cause in your case.

My code at those lines is:

#Override
public void onClick(View view) {
if (mStatePaused) {
mRemoteService.requestContinueDownload();
} else {
mRemoteService.requestPauseDownload();
}
setButtonPausedState(!mStatePaused);
}
});
When I tried locally to, I can validate the file. I also tried the same code via beta testing (just the sample downloader, not the whole project). All buttons seemed to be working. Tried downloading in the test project over wifi, over cellular and everything looked good.
Any thoughts?
I am attempting to run a basic application on Red5 that just makes an attempt to connect to the red5 server (on localhost). The source for this application is below:
import org.red5.server.adapter.ApplicationAdapter;
import org.red5.server.api.IConnection;
import org.red5.server.api.scope.IScope;
// import org.red5.server.api.service.ServiceUtils;
/**
* Sample application that uses the client manager.
*
* #author The Red5 Project (red5#osflash.org)
*/
public class Application extends ApplicationAdapter {
/** {#inheritDoc} */
#Override
public boolean connect(IConnection conn, IScope scope, Object[] params) {
return true;
}
/** {#inheritDoc} */
#Override
public void disconnect(IConnection conn, IScope scope) {
super.disconnect(conn, scope);
}
}
My client code is also pretty basic. For brevity, the snippet is below:
public function onCreationComplete(event:FlexEvent) : void {
// setup connection code
connection = new NetConnection();
connection.connect("rtmp://localhost/Player");
connection.addEventListener(NetStatusEvent.NET_STATUS, onConnectionNetStatus);
connection.client = this;
}
public function onConnectionNetStatus(event:NetStatusEvent) : void {
// did we successfully connect
if(event.info.code == "NetConnection.Connect.Success") {
Alert.show("Successful Connection", "Information");
} else {
Alert.show("Unsuccessful Connection "+event.info.code, "Information");
}
Note that I make the alert box show the error code so I can see what happens.
On the client side, when I attempt to connect, I get two failure messages:
Unsuccessful Connection NetConnection.Connect.Closed
Unsuccessful Connection NetConnection.Connect.Rejected
And on the server side I am seeing the following:
[INFO] [NioProcessor-10]

It seems clear that something is wrong due to some kind of mis- configuration. Unfortunately, I have no idea where to look for the problem.
Could someone please give some idea of what is going wrong and how I can fix this? Thank you...

Another Fact could be that u have 2 Red5.jars so u have to delete one. In my case it worked rly good.
Big Ty for this post
Change org.red5.server.WebScope to org.red5.server.scope.WebScope in your red5-web.xml file.
what version of Red5 is that?
Are there any exceptions when you startup your custom webapp? There might be already an error in the startup of the server that consequently leads to your issue.

The application scope that you are attempting to connect to "Player" does not exist on the server; the log notes this as "Scope Player not found on localhost". What this means in general is that your application didn't load. The reason that it didn't load looks like class package error for WebScope. Change the beans class attribute to org.red5.server.scope.WebScope and try again.
