Spring 3 NoClassDefFoundError: org/springframework/expression/PropertyAccessor

[javapda]

I have spring-framework-3.0.0.M3 (Spring 3).

Building a very basic app that simply reads in a simple bean configuration file. Appears to be a dependency issue as I am getting a NoClassDefFoundError , the following stack trace:

Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/expression/PropertyAccessor
	at org.springframework.context.support.AbstractApplicationContext.prepareBeanFactory(AbstractApplicationContext.java:441)
	at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:352)
	at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:139)
	at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:93)
	at com.jgk.spring3.simple.CheckSpringApp.main(CheckSpringApp.java:10)

The artifacts are

• Spring configuration file

• Main Application

• Single POJO bean to be wired

• Library dependencies

Spring configuration file: simple.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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

  <bean id="simplePersonPojo" class="com.jgk.spring3.simple.SimplePersonPojo">
  </bean>

</beans>

Main Application

package com.jgk.spring3.simple;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class CheckSpringApp {

	public static void main(String[] args) { 
		// exception thrown on the following line:
		ApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "simple.xml",});
		
	}

}

Single POJO bean to be wired

package com.jgk.spring3.simple;

public class SimplePersonPojo {
	private String title;
	private String address;
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}

	public String getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}
}

Library dependencies

• commons-logging-1.1.1

• org.springframework.asm-3.0.0.M3

• org.springframework.beans-3.0.0.M3

• org.springframework.code-3.0.0.M3

• org.springframework.context-3.0.0.M3

• log4j-1.2.14

Any suggestions?

Thanks :-)

It looks like you need to include the spring expression jar.

BTW, are you including Spring core?

[javapda]

Thank you Bron,

I was missing that library. The original post above should be modified to include the following minimal library dependencies:

Library dependencies

• antlr-3.0.1

• commons-logging-1.1.1

• org.springframework.asm-3.0.0.M3

• org.springframework.beans-3.0.0.M3

• org.springframework.core-3.0.0.M3

• org.springframework.context-3.0.0.M3

• org.springframework.expression-3.0.0.M3

Thanks again

[Bron]

So, just a clarification: is the problem still happening?

[javapda]

No, it is not still happening.

Thanks again

It seems that the expression module is a basic dependency and not only if you use SpEL as my first impression was

[Garoad]

If these are all "basic" dependencies, why are they split up in to 5 jars, if I may ask?

Hi,
I am getting the same error even though I have org.springframework.expression bundle installed and running in the equinox. I also have the following deployed:
org.springframework.aop
org.springframework.asm
org.springframework.beans
org.springframework.context
org.springframework.core
org.springframework.osgi.core
org.springframework.osgi.extender

What am I missing? Thanks,

We still have the same issue NoClassDefFound org.springframework.expression.PropertyAccessor when trying to run Spring WS samples.

Any idea why this class is missing ?

I got the same problem ,Have you solved it?
