I am trying to learn Spring in java. I am stuck at the beginning when i run the fist program.
i am trying to call the draw method of the Triangle class .
But i am seeing many errors.
In the DrawingApp.java class eclipse is showing some warning - ( The type XmlBeanFactory is deprecated ).
I am providing my implementation along with errors below.
Triangle.java
package org.hemant.spring;
public class Triangle {
public void draw(){
System.out.println("Triangle drawn");
}
}
DrawingApp.java
package org.hemant.spring;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.FileSystemResource;
public class DrawingApp {
/**
* #param args
*/
public static void main(String[] args) {
BeanFactory factory = new XmlBeanFactory(new FileSystemResource("spring.xml"));
Triangle triangle = (Triangle)factory.getBean("Triangle.class");
triangle.draw();
}
}
spring.xml

You should replace http://www.springframework.org/dtd/spring-bean-2.0.dtd with http://www.springframework.org/dtd/spring-beans-2.0.dtd (notice beans, not bean) in your spring.xml.
This:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE bean PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-bean-2.0.dtd">
<bean>
<bean id="triangle" class="org.hemant.spring.Triangle"/>
</bean>
should be something like
<?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="triangle" class="org.hemant.spring.Triangle"/>
</beans>
Also, like mentioned in the comments, factory.getBean("Triangle.class"); should be factory.getBean("triangle");
For context, I'd rather do
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
...
ApplicationContext context = new ClassPathXmlApplicationContext(
"spring.xml"); // or FileSystemXmlApplicationContext, if .xml is not in class path
Triangle obj = (Triangle) context.getBean("triangle");
And why are you using version 2.0 of Spring (based on your dtd)? That's really old.
Please do not use XmlBeanFactory anymore, use the DefaultListableBeanFactory because it seperates the reader from the factory and represent a more clean OOD.
It is not realy a error, its a format-problem with the configuration (i work that out to explain why eclipse not giving you a messages). You see, a configuration that could not be read is not a error. This means your application works great (be proud of your first try), but the configuration is wrong! To solve the configuration drop that doctype and ns.
Triangle triangle = (Triangle)factory.getBean("Triangle.class"); will not find a definition. Use Triangle triangle = factory.getBean(Triangle.class); instead because you have not to cast.
So the main should be like this:
DefaultListableBeanFactory factory = new DefaultListableBeanFactory();
XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(factory);
reader.loadBeanDefinitions(new FileSystemResource("spring.xml"));
Triangle triangle = factory.getBean(Triangle.class);
triangle.draw();

I'd at least try removing the name= attribute from the <constructor-arg>. This is not strictly necessary if there is only one constructor that could possibly match, and while what you have seems like it should work, the error message does seem to indicate something related to name resolution.
com.spring.core and com.spring.asm jar files must be different versions in your project.
asm jar hasnt been updated in a long time thats why you need to downgrade your core jar file.

I have faced the same problem.
I made some changes in my pom.xml. Ff you are using the dependency of javax mail as well aws sdk then make sure that javax mail should be declare before the aws sdk's.
If you change the sequence then it will show the above error as it's loading jars in wrong sequence.As this worked in mine case, Hope this will work for you!
Problem solved. After I install Windows10, it broke my access to folders when I have save the external jars of frameworks.
I'm a newbie for Spring and I was referring to this tutorial for my first Spring project. After follow all the instruction, I try to run the program but I'm having this error.

Check if you have added all the required jars in your classpath.
The class org.springframework.expression.ParserContext lies inside spring-expresssion-YOUR_SPRING_VERSION.jar Check if you have this jar added on classpath.
I was having the same issue. But I found my mistake.
My mistake was, I created "Beans.xml" inside com.tutorialspont package.
The solution for me was "Beans.xml" has to be created directly under src folder.

From morning facing Exception while running struts2 apps....application was working yesterday
There's a problem in loading some struts2-jquery jar even though they exist in WEB-INF/lib
After browsing I got some solution to make change in struts.xml <!DOCTYPE ....>
like changing
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
to
<!DOCTYPE struts SYSTEM "../dtds/struts-2.0.dtd">
or
<!DOCTYPE struts SYSTEM "struts-2.0.dtd">
For local referencing struts.dtd but none of these working..

This has been resolved and was due to a change in Apache project publishing mechanisms.
For details :
https://issues.apache.org/jira/browse/WW-3979
well I'm runnning this code and it cant' find the springconfig4.xml file:
package com.nortal.pirs.test.independant;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test4 {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("/com/nortal/pirs/beans/springconfig4.xml");
BeanFactory factory = context;
Test3 instance = (Test3) factory.getBean("Test3");
instance.run();
}
}
I mean I was kind of expecting it not to work, because in Java it never works when you try to use a path that is not in your current package. However as many Spring tutorials I've seen, they all show this way of specifying the configuration file.
Now my springconfig4.xml is in my applications' src/com/nortal/pirs/beans folder. So how do I specify it so that it can be found here?
The current Test4 class is located in src/com/nortal/pirs/test/independant folder.

You need to download the spring-asm-3.1.2.RELEASE.jar file from the maven repo (supposing that you are using spring 3.1.2) or if you are using maven, edit your pom.xml file and add the next lines:

</dependency>
Also, this line:
ApplicationContext context = new ClassPathXmlApplicationContext("/com/nortal/pirs/beans/springconfig4.xml");
Has an error, the path must not start with a trailing /., so the path to the file becomes: "com/nortal/pirs/beans/springconfig4.xml".
The ClassPathResource javadoc states that it will be removed anyways:
Create a new ClassPathResource for ClassLoader usage. A leading slash
will be removed, as the ClassLoader resource access methods will not
accept it.
Exception says it is not finding a class, not Spring context xml
Caused by: java.lang.ClassNotFoundException: org.springframework.asm.ClassVisitor
please add asm dependency
<dependency>
<groupId>org.springframework</groupId>
<artifactId>org.springframework.asm</artifactId>
<version>3.1.0.RELEASE</version>
</dependency>
Add spring-asm-3.0.1.RELEASE.jar and spring-expression-3.0.1.RELEASE.jar.
java.lang.ClassNotFoundException: org.springframework.asm.ClassVisitor
Just add the spring-asm-3.1.2.RELEASE.jar file. Place it in your lib folder.
For the above problem as mentioned above these jars are missing namely 1.org.springframework.asm-3.0.1.RELEASE-A.jar
2.org.springframework.expression-3.0.1.RELEASE-A.jar
or
Add all the core Jars of Spring so that any new programmer can Run all basic level programs.
There is no need of below line in your program. insted of that you can use context insted of factory in the above program.
BeanFactory factory = context
We usually use ApplicationContext insted of BeanFactory.
Even if you use BeanFactory there will be no effect for the program.
Add the Jars which is shown in the Screen short and it will work
