I'm trying to set up a simple proof of concept Rest service using a Stateless EJB bean deployed into OpenEJB.
I'm using openejb 4.6.0.2

The null pointer is thrown on this call:
final RsRegistry.AddressInfo address = rsRegistry.createRsHttpListener(contextRoot, listener, classLoader, nopath.substring(NOPATH_PREFIX.length() - 1), virtualHost, auth, realm);
virtualHost, realm and auth all appear set in the openejb properties.
The contextRoot should default to the war name, is there a better place to set this specifically?
I'm not sure what else on here would throw a null pointer without causing bigger problems somewhere else in the container. The .war is deployed with no internal jars, just the rest bean and an extension of javax.ws.rs.core.Application.

The WSO2 Business Rule Manager fails when deploy. I'm using Docker to comunicate WSO2-dashboard and WSO2-worker.

This can occur if the siddhi app created by the business rules manager is incorrect.
One possible reason for this is using an invalid siddhi app template to create business rules.
Therefore, can you check the following?
Create a siddhi app by filling up the templated fields in your templated siddhi app.
Copy that siddhi file to $SP_HOME/wso2/worker/deployment/siddhi-files directory.
Start the worker runtime.
If there is any issue with the template, it worker will fail to deploy that siddhi app and it will log the relevant error.
it's a very basic example.
I wanted to load the web application using jetty like below.
public static void main(String[] args) throws Exception {
Server server = new Server(8085);
WebAppContext webapp = new WebAppContext( "D:/workspace/camel/TestWithGradle/src/main/java/sample.war" , "sample");
webapp.setExtractWAR(true);
webapp.setParentLoaderPriority(true);
server.setHandler(webapp);
server.start();
server.join();
}
And the war is https://github.com/heroku/heroku-deploy/blob/master/spec/resources/sample-war.war
it's very simple war that uses jsp files and java servlet.
But, I run this application, the console gave the exception..

Please, help me with the elaborate explanation. thanks for reading and your time.
You have an XML with a bad DTD or namespace declaration.
The startup is attempting to fetch some sort of resource from a remote URL that would be used in validating the XML.
This will not happen with a normal jetty distribution, or the normal jetty jar artifacts.
Start with making sure you are using the official jetty jars, don't repackage them, don't uberjar them, don't one-jar them, leave them alone (for now).
Then make sure you have no typos in your various XML files. Especially in your war file, and all of the contents of the WEB-INF/lib/*.jar files. There is likely a small typo or reference that is incorrect enough that Jetty can't shortcut that remote resource request with the validation resources that comes with the jetty jars.
I am trying to integrate external cassandra to BAM. I have changed cassandra-component.xml.
1) I want to know how keyspace are created on external cassandra because when I am running BAM,
I am getting the error Unknown keyspace EVENT_KS.
2) I am having the following error in my wso2 logs

Caused by: org.apache.thrift.transport.TTransportException
EVENT_KS is created only after the very first event is published to BAM as I remember. If you try to access it before getting created errors may arise.
In BAM 2.4.0, EVENT_KS is getting created when you run the BAM for the first time. (But in previous versions EVENT_KS will be created when the very first event is published to BAM). Please make sure your cassandra-component.xml looks similar to something like below. Also tell us about the cassandra version you are using.
<Cassandra><Cluster>
<Name>Test Cluster</Name>
<DefaultPort>9160</DefaultPort>
<Nodes>localhost:9160</Nodes>
<AutoDiscovery disable="false" delay="1000"/>
</Cluster></Cassandra>
First You need to check the following:
Have you pointed the cassandra-component.xml correctly to the external cassandra. With this your published data will be stored in the intended external cassandra database.
Have you installed a toolbox with intended stream definition inside? Or Else have you triggered to publish the data to BAM? In both cases the EVENT_KS will be created with the column family with the name of stream.
Have you modified the $BAM_HOME/repository/conf/datasource/master-datasource.xml to point to external cassandra databse? You need to validate the cassandra database configuration provided in WSO2BAM_CASSANDRA_DATASOURCE datasource. For the default toolboxes, this is the default cassandra datasource being used and by default it points to localhost. If you are using this in your hive script you need to change this configuration.
After putting many efforts i figure that after changing data directory of cassendra.yaml of external cassandra to repository/database/cassandra/data everything works fine with external cassandra.Not to mention with version 1.1.3. I want to know is there any other work around for this external cassandra configuration.
I created a web app which use mysql. I used spring for the persistence.
Every thing worked on my local tomcat server.
I upload it into cloudfoundary, I follow the instuction and I create a mysql service and I use it
as a service for my web-app.
I try to run the app and I got the following exceptions:

Apache Tomcat/6.0.35
If the problem is still there: there are 2 ways to configure a connection to CF services.
1) Taking the advantage of "auto-reconfigure". For any Java app, if it is using Spring framework, the doc here specifically described the details: http://docs.cloudfoundry.com/frameworks/java/spring/spring.html
2) For Java apps, other than Spring apps, the details of connection to the CF provisioned services like hostname or password needs to be taken care explicitly. These can be retrieved by an environment variable named "VCAP_SERVICES". Simply this code snippet can achieve that:
System.getenv("VCAP_SERVICES")
After that set the properties to the connection configuration.
I'm getting an exception being thrown when I try and list my Axis-powered web services, when I try and access the WSDL for any service and when I try and use the service in question:
Servlet.service() for servlet AxisServlet threw exception
java.lang.NoClassDefFoundError: com.example.MyAwesomeServiceSoapBindingImpl
Now, I know that class is available in a jar in the Axis web service's WEB-INF/lib directory, and I have reloaded Axis since I put it there.
Any ideas, anyone?
[tomcat 5.5.x, Apache Axis version: 1.4 Built on Apr 22, 2006 (06:55:48 PDT)]
The object that MyAwesomeServiceSoapBindingImpl wraps isn't instantiating property.
I'm guessing that underlying problem is masked by this (apparently totally unrelated at first glance) type of problem because of the way Axis initialises its services...
Once I fixed the underlying problem everything kicked back into life.
