spring bean property is not writable or has an invalid setter method

[Kshitiz Agarwal]

Hi,

I am using spring in my application and m facing this problem:

SEVERE: Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MCQSingleAnsController' defined in ServletContext resource [/WEB-INF/enrapp-servlet.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'questionValidatorInterface' of bean class [com.infosys.enr.question.controller.MCQSingleAnsController]: Bean property 'questionValidatorInterface' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

The code of class MCQSingleAnsController.java is:

package com.infosys.enr.question.controller;
import com.infosys.enr.question.domain.QuestionDomain;
import com.infosys.enr.question.domain.MCQSingleAnsDomain;
import com.infosys.enr.question.validator.MCQSingleAnsValidator;
import com.infosys.enr.question.validator.QuestionValidatorInterface;
import com.infosys.enr.question.manager.MCQSingleAnsManager;
import com.infosys.enr.question.manager.QuestionManagerInterface;
import com.infosys.enr.question.exception.createQuestionPermissionDeniedException;
import com.infosys.enr.question.controller.QuestionControllerInterface;

@SuppressWarnings("unused")
@Controller
@RequestMapping(value="/question.jsp?typeId=1", method = RequestMethod.POST)

public class MCQSingleAnsController implements QuestionControllerInterface {
	
	private QuestionValidatorInterface questionValidatorInterface;
	private QuestionManagerInterface questionManagerInterface;
	
		
	/* Create question method*/
	
	public QuestionValidatorInterface getQuestionValidatorInterface() {
		return questionValidatorInterface;
	}

	public void setQuestionValidatorInterface(
			QuestionValidatorInterface questionValidatorInterface) {
		this.questionValidatorInterface = questionValidatorInterface;
	}

	public QuestionManagerInterface getQuestionManagerInterface() {
		return questionManagerInterface;
	}


	public void setQuestionManagerInterface(
			QuestionManagerInterface questionManagerInterface) {
		this.questionManagerInterface = questionManagerInterface;
	}

}

And spring config file is:

<bean id="MCQSingleAnsValidator" class="com.infosys.enr.question.validator.MCQSingleAnsValidator" />
<bean id="MCQSingleAnsManager" class="com.infosys.enr.question.manager.MCQSingleAnsManager" />

<bean id="MCQSingleAnsController" class="com.infosys.enr.question.controller.MCQSingleAnsController">
<property name="questionValidatorInterface" ref="MCQSingleAnsValidator"/>
<property name="questionManagerInterface" ref="MCQSingleAnsManager"/>
</bean>

Here,

MCQSingleAnsValidator implements questionValidatorInterface
MCQSingleAnsmanager implements questionmanagerInterface

What is the problem...all setters are correct...

[Murali Ranga]

config file
questionValidatorInterface :com.infosys.enr.question.validator.MCQSingleAnsValidator
In java file
questionValidatorInterface:com.infosys.enr.question.validator.QuestionValidatorInterface

change code in java file as

private MCQSingleAnsValidator questionValidatorInterface;

Thanks for the reply.. I did it but the same error is coming

The modified java file is:

public class MCQSingleAnsController implements QuestionControllerInterface {
	
	
	private MCQSingleAnsValidator  questionValidatorInterface;
	private QuestionManagerInterface questionManagerInterface;
	
		
	/* Create question method*/
	

	public QuestionManagerInterface getQuestionManagerInterface() {

	}


	public MCQSingleAnsValidator getQuestionValidatorInterface() {

	}


	public void setQuestionValidatorInterface(

		this.questionValidatorInterface = questionValidatorInterface;
	}


	public void setQuestionManagerInterface(
			QuestionManagerInterface questionManagerInterface) {
		this.questionManagerInterface = questionManagerInterface;
	}


}

Is the problem related to jar files...like any compatibiloty issue or something...? I am using Tomcat 6, spring 3.0.6, spring-webmvc 3.0.3 and web module 2.5

Use MCQSingleAnsmanager instead of questionmanagerInterface in your java code

I did it...but no effect ...what can be the cause of error...jar files, xml config...??? I have pasted the entire code here http://forum.springsource.org/showthread.php?121005-Webpage-not-running-in-tomcat-6&p=397016#post397016
