Try adding a jboss-deployment-structure.xml to the META-INF of the top level .ear file. In the jboss-deployment-structure.xml add a dependency for org.jboss.remote-naming and org.jboss.ejb-client.
Here's some documentation on jboss-deployment-strucure.xml: Class Loading in WildFly

I have a WSDL file located under src\main\resources\wsdl\ folder and it is having multiple operations defined within it. My application is running on Weblogic 12C server. I'm trying to expose the SOAP web-service using Apache Cammel (version: 2.18.3) with Java DSL -
I have written below code under configuration method of my RouteBuilder class -
CxfComponent cxfComponent = new CxfComponent(getContext());
CxfEndpoint serviceEndpoint = new CxfEndpoint("/soap/Manage_Order", cxfComponent);
serviceEndpoint.setAddress("http://<IP>:<PORT>/myproject/soap/ManageOrder_Details");
serviceEndpoint.setServiceClass(
"Fully qualified service interface name generated from WSDL file using maven with #WebService annotation");
serviceEndpoint.setEndpointName(<end point name defined in the service class with #WebEndpoint annotation>);
serviceEndpoint.setDataFormat(DataFormat.MESSAGE);
serviceEndpoint.setDefaultOperationName("manageOrder");
getContext().addEndpoint("myServiceEndPoint1", serviceEndpoint);
from("cxf:myServiceEndPoint1").log("Hi, I am here").end();
While I'm deploying the application, it is throwing below exception -
weblogic.application.ModuleException: java.lang.IllegalArgumentException: serviceClass must be specified

As the error says, you have not mentioned the service class and endpoint names.serviceEndpoint.setServiceClass("Fully qualified service interface name generated from WSDL file using maven with #WebService annotation");
serviceEndpoint.setEndpointName(<end point name defined in the service class with #WebEndpoint annotation>);
Step 1: Generate the service from your wsdl using wsdl2java command or your choice of IDE.
Step 2: Have that in your code classpath
Step 3: Mention the class name and endpoint names in the above piece of code
I'm trying to set up my Spring MVC app to send email, but i think i'm doing something wrong in the configuration
In My AppConfig i instantiate the Bean:
#Bean
public JavaMailSender mailSender() {
JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
mailSender.setDefaultEncoding("UTF-8");
return mailSender;
}
Then in my application.properties I have:
mail.port= 465
mail.host= smtp.gmail.com
mail.username= username
mail.password= password
emailTo = info#beingsmart.it
emailSubject = ALERT - ePark Server
mail.smtp.auth = true
mail.smtp.starttls.enable = true
mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
mail.properties.mail.smtp.socketFactory.fallback = false
When I try to send the email i'm getting

EDIT
I added javax mail to my pom
<dependency>
<groupId>javax.mail</groupId>
<artifactId>javax.mail-api</artifactId>
<version>1.5.6</version>
</dependency>
Now I have a different exception when trying to send the email
java.lang.NoClassDefFoundError: com/sun/mail/util/MessageRemovedIOException
It looks like an authentication error, but i'm thinking that JavaMailSender does not takes the setting in my application.properties, could it be?
Thanks
It seems to be missing dependency rather than anything else. If using spring boot have dependency like:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
If you don't I suggest you look inside that POM and figure out what are the missing pieces.
In your particular case it seems you need:
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.5.5</version>
</dependency>
Generic advice:
ClassNotFoundException means class which you need is not on classpath. It's usually a missing dependency
Google to find which jar contains the missing class
Find the library it on maven central
Add to dependencies

Can anyone please help me fixing this.
This is my driver class.

Looks like you are running the wordcount example, what it requires are 1.2.1 hadoop-core and 2.2.0 hadoop-common. If you use Maven instead, the config should be as simple as
<dependency>

Test.java class is present in testclient.jar & testclient.jar has been deplyed as a module using command

package com.testmodule.pojo;
import java.util.Properties;
import javax.naming.Context;

jndiProps.put("jboss.naming.client.ejb.context", true);
Context context = new InitialContext(jndiProps);
}
catch(Exception e){e.printStackTrace();}
}}
why this error has been occurred, For visiblity of 'org.jboss.naming.remote.client.InitialContextFactory' to testclient.jar, should i have to add more dependencies(currently only javax.api) while deploying testclient.jar as a module? or any other issue which is causing error? Class 'org.jboss.naming.remote.client.InitialContextFactory' is also present in $WILDFLY_HOME/bin/client/jboss-client.jar
Note - 291.861.301.732 is the remote system ip, on which ejb is deployed at jboss. ,This ejb is invoking from Test.java(remote client) using JNDI.
There is no jnp in wildfly-9.0.2.Final(which was in JBOSS 5.x), so i replaced property "org.jnp.interfaces.NamingContextFactory" to value org.jboss.naming.remote.client.InitialContextFactory". why still error is occurred?
Following has been added after receving comment 'Try putting jboss-client.jar in the runtime path, as part of WEB-INF/lib maybe' by 'Sampada Wagde'
I am not able to understand, In this scenarion test.jsp (present in test.ear-->test.war-->test.jsp) file is calling function getDbConnection of Test.java file. Test.java file is present in testclient.jar and this testclient.jar has been deployed as a module.
As per your suggestion, when i put 'jboss-client.jar' in test.ear-->test.war-->WEB-INF-->lib, problem was solved, now while accessing
application 'org.jboss.naming.remote.client.InitialContextFactory' ClassNotFound exception was not occurred...But my problem is that there are multiple war's files(Eg..test.war,test1.war,test2.war) and each war file is accessing Test.java file(present in testclient.jar), so i have to put 'jboss-client.jar' file in WEB-INF/lib of each war archive. which will be very complex for me, is there any other approach available? and secondly how this problem is solved by putting 'jboss-client.jar' into WEB-INF/lib direcory as 'org.jboss.naming.remote.client.InitialContextFactory' is present in testclient.jar(Not in test.ear-->test.war).
Following has been added after receving reply 'jboss-client.jar is required by the server at runtime...' by 'Sampada Wagde'
I also tried following steps
1. By putting 'jboss-deployment-structure.xml' in test.ear-->META-INF-->jboss-deployment-structure.xml
<?xml version="1.0"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
<deployment>

Deploying module name as

jboss-client.jar is required by the server at runtime. There are several ways of providing jars to a JBoss server -
include jars in MANIFEST.MF (this is generally used for your own application jars)
include jars in WEB-INF/lib - if the jar is specific to the given web project or WAR
include jars in a module class loader and provide it to the web project via jboss-deploymet-structure.xml . This is done when there are multiple WARS and some of them (not all) need the jars.
include jars in a module class loader and provide it to the server via global modules in standalone.xml . This is done when the jars are being referenced by all applications deployed on the server.
For details on modules in JBoss, please refer to this link -
https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7
As to your question on how putting the jboss-client.jar in a WAR instead of testclient.jar is resolving the issue, the answer is the same - this is how class loading works.
You need to make your own module depend on a module that contains not only the jboss-client jar, but also all the dependencies of jboss-client, this might just be other modules or possibly other jars too. The first class it's moaning about being missing is javax/naming/spi/InitialContextFactory so edit the module.xml for the jboss-client module to depend on javax.api
I want to inject Mongo database (com.mongodb.DB) into OSGI Web Bundle Project, using #Resource.
The application is to deployed to WebSphere Liberty Profile V8.5.5.1.
Is this possible to do it?
I got an error message
"....The annotations could not be obtained because of the exception : java.lang.NoClassDefFoundError"
However, I can inject Mongo database into WAR, using #Resource, running on WebSphere Liberty Profile, if not using OSGI.
Below is lookup return null.
public static final DB getMongoDB() throws NamingException {
InitialContext ic = new InitialContext();
DB lookup = (DB) ic.lookup("java:comp/env/mongo/testdb");
return lookup;
}
The web.xml is

<resource-env-ref-name>mongo/testdb</resource-env-ref-name>
<resource-env-ref-type>com.mongodb.DB</resource-env-ref-type>
</resource-env-ref>
