Can't read XML definition file

[ellisyu]

Dear All,

I'm building an Eclipse RCP application using Eclipse 3.7.1 and Spring 3.0.6. I use Java based container configuration method to setup the spring. In my unit test, that's fine without any problem. However, when I use AnnotationConfigApplicationContext to initiate my main program, it can't find my xml file. Below is the error message.

Caused by: org.springframework.beans.factory.BeanDefinitionSt oreException: IOException parsing XML document from class path resource [app-context.xml]; nested exception is java.io.FileNotFoundException: class path resource [app-context.xml] cannot be opened because it does not exist

That's what I don't understand, it has same spring configuration and read same xml file as my unit test . Below is my coding.

JpaConfiguration.java
===============

package com.rainbow.claim;

import java.util.HashMap;
import java.util.Map;

import javax.sql.DataSource;

import org.hibernate.cache.HashtableCacheProvider;
import org.hibernate.dialect.DerbyDialect;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.JpaVendorAdapter;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.Database;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.PlatformTransactionManager;

@Configuration
@ImportResource("classpath:/app-context.xml")
public class JpaConfiguration {

	private @Value("${jdbc.url}")
	String url;
	private @Value("${jdbc.showSql}")
	boolean showSql;
	private @Value("${jdbc.username}")
	String username;
	private @Value("${jdbc.password}")
	String password;
	private @Value("${hibernate.formatSql}")
	String formatSql;
	private @Value("${hibernate.hbm2ddl.auto}")
	String hbm2ddl;

	@Bean
	public DataSource dataSource() {
		return new DriverManagerDataSource(url, username, password);
	}
             ....

app-context.xml
==============

</beans>

LoginUserRepositoryTest.java
======================

package com.rainbow.claim;

import static org.junit.Assert.assertEquals;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;

import com.rainbow.claim.entity.User;
import com.rainbow.claim.service.LoginUserService;

@ContextConfiguration(locations = { "classpath:/app-context.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
@Transactional
public class LoginUserRepositoryTest {

	@Autowired
	LoginUserService userSrv;
	User user;

	@Before
	public void setUp() {
		user = new User();
		user.setUserId("userid");
		user.setUsername("username");
		user.setPassword("password");
	}

	@Test
	public void testCrud() {
		user = userSrv.save(user);
		assertEquals(user, userSrv.findByUserId(user.getUserId()));
	}

	@Test
	public void testMethodQuery() throws Exception {
		Boolean succeed = false;

		user = userSrv.save(user);
		succeed = userSrv.authenticate("userid", "password");
		assertEquals(succeed, true);
	}
}

Activator.java
===========

	public void start(BundleContext context) throws Exception {
		super.start(context);
		plugin = this;
		ctx = new AnnotationConfigApplicationContext(JpaConfiguration.class);
	}

Did anyone know what's the problem in my coding?

Are you positive the xml file is being copied into your classpath in your application. Whereas it is already in your classpath in your text.

Also, if it is copying it, are you positive that the xml file is at the root of your classpath? If it is further in your classpath, you will have to tell Spring exactly the package path to go to.

What are you using to build your app, are you using Maven? Ant?

Thanks Mark, I'm sure the xml file is copied into classpath. I'm using Eclipse 3.7.1 RCP to build my application. I didn't use either Maven or Ant for my program.

My xml file put in the root of src folder.

com.rainbow.claim
|
|__src
| |_app-context.xml
|
|__test

First I noticed you had


<context:component-scan base-package="com.rainbow.claim" />
<context:component-scan base-package="com.rainbow.claim.service" />

That is redundant. The first component scan will also scan subpackages under com.rainbow.claim. So that already includes com.rainbow.claim.service.

For file not found. try

"classpath:app-context.xml"

The forward slash in front is not needed. If you look at your archive created after compiling, do you see the app-context.xml in the actual root of your classpath?

Thanks

Mark

After struggling this problem for few days, I think the problem was caused by using RCP. Since RCP is based on OSGi archecture, it seemed the classloader causing this problem. I think I may need to change using Eclipse Gemini (Former: Spring DM) to solve my problem. If anyone know better solution on this, please kindly let me know.
