I have this very simple project made with NetBeans 8.1 (new project > Maven > Java application):
Here's App.java:
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class App {
public static void main(String[] args) {
System.out.println("why");
ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
MyObject obj = (MyObject) context.getBean("myobj");
obj.getMessage();
}
}
This is MyObject.java:
public class MyObject {
private String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
And Beans.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean id="myobj" class="asd.spring1.MyObject">

</bean>
</beans>
pom.xml:

As you can see I have put Beans.xml everywhere. Do you know why am I getting error and how can I fix this?
You can check compiled JAR that it doesn't contain Beans.xml. See explanation below.
First of all, you shouldn't place non-java files to src/main/java directory.
Secondly, you can check Maven's build output (default invocation of resources plugin): it uses src/main/resources directory to search resources by default.
As a result, you should to place your XML files to src/main/resources directory.
See Maven Resources Plugin for more details.
Do you have your Beans.xml inside target folder, you need to have your xml file somewhere inside directory where your compiled classes are.
Also if you have building and running your app with ID (so it compiles and moves classes by default in some folder), you can also try to put
ApplicationContext context = new ClassPathXmlApplicationContext("classpath*:Beans.xml");
to be sure to check all packages in classpath for your config class.

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="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<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!

Like the error message says, Beans.xml is not found in your classpath (in the given path, i.e. root). If you have placed the file next to the Java classes in com/hello, then use the path com/hello/Beans.xml in your main method.
I am having problem trying to run my first spring application that displays Hello world at my console. I am getting this error.

here is the Beans.xml file:
<?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="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-
3.0.xsd">
<bean id="helloWorld" class="com.tutorialspoint.HelloWorld">
<property name="message" value="Hello World!"/>
</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");
