Error in spring context.xml

[looka dicosta]

Hello Every One,

I have class A with constructor argument as (URI uri, Image image), where URI is java.net.URI and Image is java.awt.Image. I am trying to configure it via spring as:

<bean id="a" class="some package">
    <constructor-arg  type="java.net.URI" value=""/>
	<constructor-arg type="java.awt.Image" value=""/>

But error is thrown as : Exception in thread "main" org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'a' defined in class path resource [/context.spring.xml]: Unsatisfied dependency expressed through constructor argument with index 1 of type [java.awt.Image]: Could not convert constructor argument value of type [java.lang.String] to required type [java.awt.Image]: Failed to convert value of type 'java.lang.String' to required type 'java.awt.Image'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [java.awt.Image]: no matching editors or conversion strategy found.

Please do provide your valuable suggestions.

Regards,
Looka

value="" in your constructor-arg.

value = means you want ot pass in that value, that exact String value

value="something" means the string "something" will be passed in.

If you want to reference another bean you use ref="" instead of value=""

value is value, ref is ref.

Thanks Mark. But for image if I create another bean like

 <!--Abstract Class Image  -->
    <bean id="image" class="java.awt.Image" abstract="true"/>

.

and change the above as :

    <bean id="a" class="some package">  
        <constructor-arg  type="java.net.URI" value=""/>  
        <constructor-arg ref="image"/>  

.

Then also I am getting errors.

Well, first you put

abstract="true"

This means that it is abstract and Spring will not create an object for you. Which means there is nothing to ref/inject in your other bean, hence an error.

You need would need to create a real Image instance if your constructor takes a class of that type. You can't pass a String for an Image, that is wrong types.
