What i am doing wrong here?
This question might be duplicate but i did not get answer from other post, as those solutions did not work for me.
The NoClassDefFoundError is thrown by JVM at runtime when it try to load a class that is not present in the classpath.
Check if the class in present in the classpath or not.
May be a jar is not added in the right position or it is not correctly referenced in the classpath, or the jar version is not the right one.
Note the OrderSourceProvider is present since spring 4.1. Check if the jar loaded at runtime is older than that version.

Add the following to your pom.xml (if using maven)
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>4.2.1.RELEASE</version>
</dependency>
As you can see in the stacktrace the error is java.lang.ClassNotFoundException: org.springframework.aop.TargetSource.
That means, that you miss the spring-aop.jar in your classpath.
Add it as a dependecy to your pom.xml if you work with maven. If not you have to add it and all the dependencies manually to your classpath.
You could download required jar from Maven repo. and add the same in your classpath. I hope it will work fine.
I am trying to Access Bean.xml in SpringPrgramm2 whereas Beans.xml is present in the SpringProgramm1 project. Both are java project.
Please find my code below :
SpringProramm1 java project in Eclipse :
(only Beans.xml is present in src folder)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="

<bean id="textEditor" class="com.surajhome.practice.spring.TextEditor">
<property name="spellChecker">
<bean id="spellChecker" class="com.surajhome.practice.spring.SpellChecker"/>
</property>
</bean>
</beans>
SpringPrgoramm 2 java project :
MainApp.java
SpellChecker.java
TextEditor.java
MainApp.java code below which is failing to access beans.xml from another java project.
package com.surajhome.practice.spring;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class MainApp {
public static void main(String[] args) {
ApplicationContext appContext=new ClassPathXmlApplicationContext("classpath:SpringProgram1/Beans.xml");
TextEditor obj1 = (TextEditor) appContext.getBean("textEditor");
obj1.spellCheck();
}
}
How can we access this Beans.xml file in the SpringProgramm2 project?

First, I believe that the structure of your projects is not cohesive. It does not make sense for the classes in your SpringProgramm2 project to be configured in the SpringProgramm1 project XML, as these classes belong to the SpringProgramm2 project.
So, I gave an example of how your projects would be more cohesive using Maven:
Your new SpringProgramm1 project.
Your new SpringProgramm2 project:
In my example, your SpringProgramm2 would depend on SpringProgramm1:
<dependency>
<groupId>br.edu.claudivan</groupId>
<artifactId>SpringPrgramm1</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
In SpringProgramm1, you can keep the configuration of your beans. In SpringProgramm2, you keep the MainApp.java class to load the context XML that would look like this:
public class MainApp {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("classpath:/Beans.xml");
TextEditor obj1 = (TextEditor) context.getBean("textEditor");
obj1.spellChecker();
}
}
I put the example code on my github.
Hope this helps!

</bean>
</beans>
I have create the Beans.xml file in the exact package by right clicking and adding android .xml file.
Here is the java class:
package come.tutorialspoint;
public class HelloWorld {
private String message;
public void setMessage(String message){
this.message = message;
}
public void getMessage(){
System.out.println("Your Message : " + message);
}
}
Here is the Main class:
public class MainApp {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
HelloWorld obj = (HelloWorld) context.getBean("helloWorld");
obj.getMessage();
}
}
Based on one of your last comments to the question, your Beans.xml is in the wrong location. Options:
Move Beans.xml to "src/main/resources/Beans.xml"
or
Move Beans.xml to "src/main/java/Beans.xml"
or
Change ClassPathXmlApplicationContext("Beans.xml") to ClassPathXmlApplicationContext("come/tutorialspoint/Beans.xml");
The first option is the preferred option per Java/Maven conventions.
Your error is that ClassPathXmlApplicationContext expects a classpath location, and that includes any package information. Your Beans.xml is currently sitting in the package "come.tutorialspoint";
For more info:
Spring 3 Documentation - Application contexts and Resource paths
Spring cannot find bean xml configuration file when it does exist
Keep you Bean.xml in same package of your Java files and instead Of using:
ClassPathXmlApplicationContext("Beans.xml")
Use:
ClassPathXmlApplicationContext("come/tutorialspoint/Beans.xml");

The beans file Beans.xml is not being found. You should place Beans.xml in your classpath.
Just right click on src folder in eclipse and click new then other and create a new xml file. Put all your code of beans.xml in that file.
<bean id="helloWorld" class="com.practice.HelloWorld">
<property name="message" value="Hello World!"/>
</bean>
I declared the bean as above.
Call the bean as follows.
ApplicationContext context =
new ClassPathXmlApplicationContext("Beans.xml");
HelloWorld obj = (HelloWorld) context.getBean("helloWorld");
This works for me. I can get the value of message.
Spring is looking for Beans.xml and not finding it on the class path.
The file might well be in your current working directory or somewhere else obvious to humans, but it must be on the Java class path for a ClassPathXmlApplicationContext to find it properly.
Put Beans.xml inside project Build path. Following are the steps
Right click on the project => select Build path => select configure build path
Select Java Build Path => Source => Click on Included
Then click on Add and add your Beans.xml
Final configuration is like this:
Click on Finish and save all changes. Run the project with ctrl+F11.
Go to the physical location of the application and place the .xml file
Ex :C:\Workspace\application-name\target\classes
