Strange behavior in constructor injection.

Hi, I have the following bean in my application context:

Code:

---

<bean id="lucenePath" class="java.io.File">
        <constructor-arg index="0">
                <value>C&#58;/Tomcat/pc2/WEB-INF/lucene-index</value>
        </constructor-arg>
</bean>

---

If I remove the parameter "index" in constructor-arg tag, Spring try inject dependency file path in constructor File(String, String), not in File(String). My question is: why it tries this if there is only a constructor argument?

I'm using Spring 1.1.3 and read context xml with ClassPathXmlApplicationContext class.

Best regards

Spring tries to find out what constructor to use when your class (File) has more than one constructor. You need to give Spring more informations to help it use the correct constructor.
Also, did you consider using Spring build-in Resource support?

Hi, Omar , thanks for you answer. But, if I'm setting only a parameter, Spring must not to try use two parameters constructor, must it? I think that, in this case, Spring should be skillful to find the rigth constructor. Course, if I have other one parameter constructor with other parameter type, I really need to give more information to it.
