Question

I’m trying to setup a bean factory in spring, something which should be really simple to do, but I just can’t figure out why it’s not working. Spend most of today looking at examples, reading other similar posts on stackOverflow, reading Spring In Action as well as Spring Recipes with no success so far. A second pair of eyes will probably pick up my mistake in no time.

Error Notifier Interface

public interface ErrorNotifier {
    public void notifyCopyError(String srcDir, String destDir, String filename);        
}

Error Notifier Implementation

public class EmailErrorNotifier implements ErrorNotifier {

    private MailSender mailSender;

    /**
     * Blank constructor
     */
    public EmailErrorNotifier() {
    }

    public void setMailSender(MailSender mailSender) {
        this.mailSender = mailSender;
    }

    @Override
    public void notifyCopyError(String srcDir, String destDir, String filename) {

        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom("system@localhost");
        message.setTo("admin@localhost");
        message.setSubject("Finished Uploading File");
        message.setText("Your upload failed!");

        mailSender.send(message);

    }
}

My config in applicationContext.xml

    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host" value="${email.host}"/>
        <property name="protocol" value="${email.protocol}"/>
        <property name="port" value="${email.port}"/>
        <property name="username" value="${email.username}"/>
        <property name="password" value="${email.password}"/>
        <property name="javaMailProperties">
            <props>
                <prop key="mail.smtp.auth">true</prop>
                <prop key="mail.smtp.starttls.enable">true</prop>
            </props>
        </property>
    </bean>

    <bean id="errorNotifier" name="errorNotifier"  class="com.bdw.controller.EmailErrorNotifier">           
        <property name="mailSender" ref="mailSender"/>
    </bean>

And the class in which I test it

public class test {

    public static void main(String[] args) {

        ApplicationContext context =
                new ClassPathXmlApplicationContext(
                ApplicationContext.CLASSPATH_ALL_URL_PREFIX
                + "applicationContext.xml");

        ErrorNotifier notifier =
                context.getBean("errorNotifier", ErrorNotifier.class);
        notifier.notifyCopyError("test", "test", "test");

    }
}

I don’t get any errors in tomcat or glassfish logs, just this output:

Exception in thread “main”
org.springframework.beans.factory.NoSuchBeanDefinitionException: No
bean named ‘errorNotifier’ is defined at
org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:527)

If I change context.getBean parameter to lookup mailSender, I get No bean named ‘mailSender’.

Any ideas?

Answer 1

The applicationContext file is likely not on the class path; I’m not sure that the all_URL_prefix will dig past the root level of the filesystem and jars, making the test go wonky. Try moving the config file, or changing the list of locations from which to grab the config file.
