Executing methods in spring config xml and using its' result

Today I needed to supply cxf the password of my keystore and my certificate. I didn't want the password to stay in some config file saved as plane text. Since I'm doing everything through spring config xml (the cxf part), I wanted to check if I could invoke a method on a static class which decrypts the password, save the result and give it to cxf.

I ended up with this xml:

<bean id="decryptedPrivatePassword" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
  <property name="targetClass"><value>com.nottelling.SomeCryptoClass</value></property>
  <property name="targetMethod"><value>decryptWithDefaultInstance</value></property>
  <property name="arguments">
    <list>
      <value>${cert.private.pass}</value>
    </list>
  </property>
</bean>

This saves me the result of the description in the bean id "decryptedPrivatePassword". Now to use this result in the cxf config part I just used the notation #{beanId} like this:

<sec:keyManagers keyPassword="#{decryptedPrivatePassword}" >
  <sec:keyStore type="${cert.private.type}" password="#{decryptedPrivatePassword}" file="${cert.private.file}"/>
</sec:keyManagers>

Obviously #{beanid} resolves beans ${placeholder.name} resolves just placeholders (if you put a bean id it doesn't find it). Spring documentation referring to this

For me something new

Well I guess its time I started writting some of my adventures in Java and the likes.

So hope I will be able to help someone other than myself.
