Solution To: MyEclipse error while deploying JAX RS REST Web Service To Server


Problem: MyEclipse error while deploying JAX RS REST Web Service To Server

Error Message:
exception com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes. at com.sun.jersey.server.impl.application.RootResourceUriRules.<init>

Solution:
Add <init-param> tag
(Assuming the project package is com.myeclipseide.ws)
.
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <servlet>
  <display-name>JAX-RS REST Servlet</display-name>
  <servlet-name>JAX-RS REST Servlet</servlet-name>
  <servlet-class>
  com.sun.jersey.spi.container.servlet.ServletContainer
  </servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.myeclipseide.ws</param-value> 
</init-param> 
  <load-on-startup>1</load-on-startup>

  <servlet-name>JAX-RS REST Servlet</servlet-name>

  </servlet-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>
.

Addition:
To test the REST URL, deploy the project to server, click the "Launch REST Web Services Explorer" button (the button is available in JavaEE Perspective window).
Based on the web.xml file above, the test url would be http://localhost:8080/restdemo/services/application.wadl (Assuming the project name is restdemo)

How To: Download IBM APP Connect Enterprise



.

IBM APP Connect Enterprise

IBM APP Connect Enterprise (abbreviated as IBM ACE, formerly known as IBM Integration Bus or WebSphere Message Broker) is IBM's integration broker from the WebSphere product family that allows business information to flow between disparate applications across multiple hardware and software platforms. Rules can be applied to the data flowing through the message broker to route and transform the information. The product is an Enterprise Service Bus supplying a communication channel between applications and services in a service-oriented architecture.

Download IBM APP Connect Enterprise (IBM Integration Bus,WebSphere Message Broker):
https://www-01.ibm.com/marketing/iwm/iwm/web/pickUrxNew.do?source=swg-wmbfd&transactionid=452368858
(Note that App Connect Enterprise is the renamed version 11.0 of IIB).




 Enterprise Service Bus (ESB)

An enterprise service bus (ESB) implements a communication system between mutually interacting software applications in a service-oriented architecture (SOA). It implements a software architecture as depicted in the picture. As it implements a distributed computing architecture, it implements a special variant of the more general client-server model, wherein, in general, any application using ESB can behave as server or client in turns. ESB promotes agility and flexibility with regard to high-level protocol communication between applications. The primary goal of the high-level protocol communication is enterprise application integration (EAI) of heterogeneous and complex service or application landscapes (a view from the network level).

Service-Oriented Architecture.


Service-oriented architecture (SOA) is a style of software design where services are provided to the other components by application components, through a communication protocol over a network. The basic principles of service-oriented architecture are independent of vendors, products and technologies.[1] A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online.

A service has four properties according to one of many definitions of SOA:[2]

It logically represents a business activity with a specified outcome.
It is self-contained.
It is a black box for its consumers.
It may consist of other underlying services.

Solution To: "Content is not allowed in trailing section" in XML File




Check if your XML is properly build
<? ?>
<root>
.....

1. Check encoding, if you are using text editor encoding must be same us system encoding. If you use XML editor encoding should set proper encoding of binary data.
2. Check if there is no content between XML declaration (<?xml ?>) and root ie no plain texts. Bad encoding can make parser to treat XML declaration as the text.
3. Try open file in XML editor and validate it.
4. Is the XML empty?
