Getting BeanNotOfRequiredType exception but displayed types match
Hi all,
Been having a heck of a time figuring out how to resolve an issue I have been seeing. Can't find anything on the web similar to it.
Using Springframework version 3.0.5.RELEASE
The offending line of code is:
Code:
JMXClient myJMXConnectionInfo = myApplicationContext.getBean("jmx.client", JMXClient.class);
This is being called from a static method of the JMXClient class itself (Not sure if that matters, including this just in case)
This results in:
Code:
Caused by: org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bea
n named 'jmx.client' must be of type [com.thecompany.cds.common.jmx.JMXClient], but
was actually of type [com.thecompany.cds.common.jmx.JMXClient]

n(AbstractApplicationContext.java:1079)
at com.thecompany.cds.common.jmx.JMXClient.getRemoteJobRunner(JMXClient.java
:28)
JMXClient bean is defined as:
Code:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="placeholderPrefix" value="$simple-jmx-client{" />
<property name="locations">
<list>
<value>classpath:common-jmx/simple-jmx-client.properties</value>
</list>
</property>
</bean>
<bean id="jmx.client" class="com.thecompany.cds.common.jmx.JMXClient" >
<property name="url" value="$simple-jmx-client{jmx.url}" />
<property name="username" value="$simple-jmx-client{authorization.username:test}" />
<property name="password" value="$simple-jmx-client{authorization.password:test}" />
</bean>
The code for JMXClient is just getters and setters for the properties, the class just exists to wrap JMX properties and has a static method for retreiving remote beans.
Code:
public class JMXClient {
protected static final Logger LOGGER = LoggerFactory.getLogger(JMXClient.class);
private String url;
private String username;
private String password;
static String XML_PATH = "classpath:common-jmx/spring/simple-jmx-client.xml";
public static <S> S getRemoteBean(String objectName,
Class<S> clazz) {
ClassPathXmlApplicationContext myApplicationContext = new ClassPathXmlApplicationContext(XML_PATH);
JMXClient myJMXConnectionInfo = myApplicationContext.getBean(JMXClient.class);
...
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
(I realize creating a new ClassPathXMLApplicationContext each time is stupid, I will be refactoring this class after I figure out this issue.)
If anyone has any idea what could be going on I would appreciate some help immensely. My thinking is there must be some kind of class version issue froma potential transitive dependency, but thatis really just a shot in the dark.
This code is being called from a Maven Mojo I am working on. I have created an isolated class loader for the thread that calls this method that has the entire runtime classpath and test classes classpath as well as our conf directory.
