Problem with static factory method constructors

[halcyon]

I'm creating a javax.mail.session from the static getDefaultInstance method. the method is overloaded with 2 signatures, one with just a props, and a second with props and an authenticator. For some reason spring refuses to call just the one with a single props parameter.. here is my setup, ive tried specifiying index=0 etc, doesn't seem to help:

  <bean name="javaMailSession" class="javax.mail.Session" factory-method="getDefaultInstance">
    <constructor-arg>
      <props>
        <prop key="mail.smtp.auth">true</prop>
        <prop key="mail.smtp.host"></prop>
        <prop key="mail.smtp.port"></prop>
        <prop key="mail.smtp.user"></prop>
        <prop key="mail.smtp.password"></prop>
      </props>
    </constructor-arg>
  </bean>

Log file error:

2005-06-24 16:00:58,203 [DEBUG] support.DefaultListableBeanFactory - Ignoring factory method [public static javax.mail.Session javax.mail.Session.getDefaultInstance(java.util.Properties,javax.mail.Authenticator)] of bean 'javaMailSession': could not satisfy dependencies
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'javaMailSession' defined in ServletContext resource [/WEB-INF/spring/tecas.xml]: Unsatisfied dependency expressed through constructor argument with index 1 of type [javax.mail.Authenticator]: Ambiguous constructor argument types - did you specify the correct bean references as generic constructor arguments?

Any ideas? Thanks!

hmm the factory-method seems to need some serious work on matching provided parameters with overloaded methods... had to resort to a much more vague way of doing what i needed:

  <bean id="javaMailSession" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetClass"><value>javax.mail.Session</value></property>
    <property name="targetMethod"><value>getDefaultInstance</value></property>
    <property name="arguments">
      <list>
        <props>
          <prop key="mail.smtp.auth">true</prop>
          <prop key="mail.smtp.host"></prop>
          <prop key="mail.smtp.port"></prop>
          <prop key="mail.smtp.user"></prop>
          <prop key="mail.smtp.password"></prop>
        </props>
      </list>
    </property>
  </bean>
