ConversionNotSupportedException from String to Custom Class

My config file has the following bean

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean id="testBean" class="com.example.MyClass">
    <property name="client" value="com.example.otherclass.Other"></property>
</bean>

And my class MyClass is

public class MyClass implements MyInterface {
Other client;


@Override
public void doIt() {
    // TODO Auto-generated method stub
    try {
        System.out.println(client.getInfo());
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}


public Other getClient() {
    return client;
}


public void setClient(Other client) {
    this.client = client;
}


}

Why am I getting

Cannot convert value of type [java.lang.String] to required type [com.example.otherclasses.Other] for property 'client': no matching editors or conversion strategy found

The error is pretty self explainatory. Your setter needs an Other object and you pass it the string "com.example.otherclass.Other". Spring has some default converters, and could convert if to a Class object but not to an Other object.

If all you want is to initialize client attribute with a new Other object, you can use an anonymous(*) inner bean :

<bean id="testBean" class="com.example.MyClass">
    <property name="client">
        <bean class="com.example.otherclass.Other"/>
    </property>
</bean>

(*) in fact, the bean will be given a name by Spring, but it is called anonymous since you normally cannot use it by name (you do not know the name).

You are setting the value of client to the string com.example.otherclass.Other.

You need to do something like:

<bean id="myOther" class="com.example.otherclass.Other">
</bean>

<bean id="testBean" class="com.example.MyClass">
    <property name="client" ref="myOther"></property>
</bean>
