Invalid URL scheme name "http-remoting" occurring when running application jar

I am using one of the JBoss JMS quickstart projects (HelloWorld-JMS) which uses JMS to write to a message queue. The queue has been defined in the JBoss XML configuration file. Our application runs perfectly fine when we run it from the IDE. However, when we package it as a JAR, we start seeing the exception:
SEVERE: Exception NamingException: javax.naming.InvalidNameException: WFNAM00007: Invalid URL scheme name "http-remoting"
We have also tried:
http-remoting://127.0.0.1:8080
remoting+http://127.0.0.1:8080
But we get the same exception.
Here's the main part of my code:
private static final String DEFAULT_MESSAGE = "Hello, World!";
private static final String DEFAULT_CONNECTION_FACTORY = "jms/RemoteConnectionFactory";
private static final String DEFAULT_DESTINATION = "jms/queue/myqueue";
private static final String DEFAULT_MESSAGE_COUNT = "1";
private static final String DEFAULT_USERNAME = "john";
private static final String DEFAULT_PASSWORD = "doe";
private static final String INITIAL_CONTEXT_FACTORY = "org.wildfly.naming.client.WildFlyInitialContextFactory";
private static final String PROVIDER_URL = "http-remoting://127.0.0.1:8080";
Context namingContext = null;
String userName = System.getProperty("username", DEFAULT_USERNAME);
String password = System.getProperty("password", DEFAULT_PASSWORD);
// Set up the namingContext for the JNDI lookup
final Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);
env.put(Context.PROVIDER_URL, System.getProperty(Context.PROVIDER_URL, PROVIDER_URL));
env.put(Context.SECURITY_PRINCIPAL, userName);
env.put(Context.SECURITY_CREDENTIALS, password);
namingContext = new InitialContext(env);
// Perform the JNDI lookups
String connectionFactoryString = System.getProperty("connection.factory", DEFAULT_CONNECTION_FACTORY);
log.info("Attempting to acquire connection factory \"" + connectionFactoryString + "\"");
ConnectionFactory connectionFactory = (ConnectionFactory) namingContext.lookup(connectionFactoryString);
log.info("Found connection factory \"" + connectionFactoryString + "\" in JNDI");
The exception occurs at this line:
ConnectionFactory connectionFactory = (ConnectionFactory) namingContext.lookup(connectionFactoryString);

It looks to me like your classpath has overlapping classes on it. I see the same thing in your pom.xml. This will cause the wrong classes to be loaded at runtime.
For example, if you look at the pom.xml of the HelloWorld-JMS project you'll see that it only uses the wildfly-jms-client-bom. In fact, the whole point of such a "bom" (i.e. bill of materials) is to incorporate all the required dependencies into a single dependency. Therefore, I recommend you just use this in your pom.xml:
<dependency>
<groupId>org.jboss.eap</groupId>
<artifactId>wildfly-jms-client-bom</artifactId>
<version>7.3.4.GA</version>
<type>pom</type>
</dependency>
Likewise, on your application's classpath you should only have the dependencies of wildfly-jms-client-bom on your classpath (or aggregated equivalents).

Unable to use full text search with oak lucene

I am trying out jackrabbit oak with lucene in a file node store. The index definition record is created successfully but it seems the index record is not created.
The full project I am working on is here
What I am doing in the code is initializa a repository, create the lucene index definition, add a test data with a single property "name" with value "foo".
Sleep for 5 second for async indexing to complete, then perform the following query in a retry loop
select * from [nt:base] where contains(., 'foo').
No result is returned.
I have tried oak-run console to retrieve lc info on oak:index/lucene directory, it displays no result as well.
This is the main part of the code
public static void main( String[] args ) throws Exception
{
init();
createLuceneIndex();
createTestData();
performQuery();
}
private static void init() throws InvalidFileStoreVersionException, IOException {
LuceneIndexProvider provider = new LuceneIndexProvider();
FileStore fs = FileStoreBuilder.fileStoreBuilder(new File("repository")).build();
nodestore = SegmentNodeStoreBuilders.builder(fs).build();
repository = new Jcr(new Oak(nodestore))
.withAsyncIndexing("async", 3)
.with(new LuceneIndexEditorProvider())
.with((QueryIndexProvider) provider)
.with((Observer)provider)
.withAsyncIndexing()
.createRepository();
}
private static void createLuceneIndex() throws RepositoryException {
Session session = createAdminSession();
Node indexesNode = session.getRootNode().getNode("oak:index");
IndexDefinitionBuilder idxBuilder = new IndexDefinitionBuilder();
IndexRule indexRules = idxBuilder.indexRule("nt:unstructured");
indexRules.sync();
indexRules.property("name").analyzed().nodeScopeIndex();
idxBuilder.async("async");
idxBuilder.includedPaths("/");
Node documentIndex = indexesNode.addNode("lucene", "oak:QueryIndexDefinition");
idxBuilder.build(documentIndex);
session.save();
session.logout();
}
private static void createTestData() throws LoginException, RepositoryException {
Session session = createAdminSession();
Node test = session.getRootNode().addNode("test");
test.setProperty("name", "foo");
session.save();
session.logout();
}
private static void performQuery() throws Exception {
final Session session = createAdminSession();
TimeUnit.MICROSECONDS.sleep(5);
QueryManager qm = session.getWorkspace().getQueryManager();
final Query q = qm.createQuery("select * from [nt:base] where contains(., 'foo')", Query.JCR_SQL2);
new RetryLoop(new RetryLoop.Condition() {
public String getDescription() {
return "Full text query";
}
public boolean isTrue() throws Exception {
QueryResult r = q.execute();
return r.getNodes().hasNext();
}
}, 20, 500);

NPE while receiving messages from Azure Service bus Queue

NPE while receving messages from Queue. ( Only when messages are present in Queue). I feel like there is an issue with de-serializing the messages.
java.lang.NullPointerException
at com.sun.jersey.api.client.ClientResponse.getResponseDate(ClientResponse.java:738)
at com.microsoft.windowsazure.services.servicebus.implementation.ServiceBusRestProxy.receiveMessage(ServiceBusRestProxy.java:288)
at com.microsoft.windowsazure.services.servicebus.implementation.ServiceBusRestProxy.receiveQueueMessage(ServiceBusRestProxy.java:225)
at com.microsoft.windowsazure.services.servicebus.implementation.ServiceBusExceptionProcessor.receiveQueueMessage(ServiceBusExceptionProcessor.java:142)
RECEIVE_AND_DELETE option deletes the messages and throws NPE.
All other operations like create queue , send messages etc working fine. Any thoughts one this ?
Code to receive message
public void receiveMessage(String queueName) {
try {
ReceiveMessageOptions opts = ReceiveMessageOptions.DEFAULT;
opts.setReceiveMode(ReceiveMode.PEEK_LOCK);
while (true) {
ReceiveQueueMessageResult resultQM
= service.receiveQueueMessage(queueName, opts);
BrokeredMessage message = resultQM.getValue();
if (message != null && message.getMessageId() != null) {
log.println("MessageID: " + message.getMessageId());
// Display the queue message.
log.print("From queue: ");
byte[] b = new byte[200];
String s = null;
int numRead = message.getBody().read(b);
while (-1 != numRead) {
s = new String(b);
s = s.trim();
System.out.print(s);
numRead = message.getBody().read(b);
}
log.println("");
log.println("Custom Property: "
+ message.getProperty("MyProperty"));
// Remove message from queue.
log.println("Deleting this message.");
//service.deleteMessage(message);
} else {
log.println("Finishing up - no more messages.");
break;
// Added to handle no more messages.
// Could instead wait for more messages to be added.
}
}
} catch (Exception e) {
log.print(e);
}
}

Even though it was throwing NPE the actual issue was with the missing jar files. Here is the list of jar files

java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/JsonFactory getting this error even after adding the desired imports

here is my code. I've added all the dependencies then also getting such error.
google-http-client-jackson2-1.17.0-rc.jar
here in this code in getting above mentioned error at JsonFactory jsonFactory = new JacksonFactory();

int i=0;
for (Result r : results){
urls[i] = r.getLink();
snippets[i] = r.getSnippet();
i++;
}
return getResults(snippets, urls, true);
} catch (IOException e) {
// TODO Auto-generated catch block
MsgPrinter.printSearchError(e);
System.exit(1);
return null;
}
}
kindly suggest me how it should be fixed.

To answer the question directly (it was answered in the comments by Pavel). The jackson core lib dependency was missing:
jackson-core-$x.y.z.jar

Happened to me when having 2 jackson versions - codehaus vs. fasterlxml.
Removing the fasterxml version (that was a trans-dependency of swagger) fixed the issue.

I had a similar problem, eventually discovered it was an issue with the buildpath and dependencies. The easiest (not most efficient) is too add all the google-api-client jars to your project and it would disappear. Better way is to track and properly add all other dependencies of jacksonFactory

Down load the Maven of jackson from here.
Then add it to your dependencies.

Classes not found in maven project despite the library being included in the pom

I'm trying to run this open-source project, rokuality-server (full codebase here: https://github.com/rokuality/rokuality-server).
But in this method below I'm getting a java.lang.NoClassDefFoundError when trying to instantiate any Sikuli classes like Pattern or Finder.
import org.sikuli.script.Finder;
import org.sikuli.script.Image;
import org.sikuli.script.Match;
import org.sikuli.script.Pattern;
#SuppressWarnings("unchecked")
public class ImageUtils {
private static JSONObject getElement(String sessionID, String locator, File screenImage) {
JSONObject element = new JSONObject();
element.put(SessionConstants.ELEMENT_ID, UUID.randomUUID().toString());
boolean isFile = locator != null && new File(locator).exists();
boolean elementFound = false;
if (!screenImage.exists()) {
return null;
}
if (isFile) {
Finder finder = null;
float similarity = Float.valueOf(
SessionManager.getSessionInfo(sessionID).get(SessionConstants.IMAGE_MATCH_SIMILARITY).toString());
Pattern pattern = null;
try {
//******** THIS LINE BELOW THROWS THE ERROR ********
pattern = new Pattern(locator).similar(similarity);
finder = new Finder(screenImage.getAbsolutePath());
} catch (Exception e) {
Log.getRootLogger().warn(e);
}
}
// more code here
}
}
My suspicion is that something in the pom.xml file is wrong, so here's the Sikuli X Api dependency as it appears there:
<dependency>
<groupId>com.sikulix</groupId>
<artifactId>sikulixapi</artifactId>
<version>1.1.2</version>
<exclusions>

<artifactId>jadb</artifactId>
</exclusion>
<exclusion>
<groupId>com.sikulix</groupId>
<artifactId>sikulix2tigervnc</artifactId>
</exclusion>
</exclusions>
</dependency>
I tried changing the version to the latest one, 2.0.0 but it caused some errors in the project, which I think are related to changes in the org.sikuli.script.Image class's methods. Do I maybe need an earlier version?

This should be fixed in the newer releases of the rokuality project:
https://github.com/rokuality/rokuality-server/releases. It depended on the java jdk version the user was running.
