Bean property 'xx' is not writable or has an invalid setter?

[jonnybecker]

Hi,

can somebody tell me what this means. I'm trying to figure out where to look for the mistake (applicationContext.xml?, model-class?, mapping-file?, ???).

The error:
org.springframework.beans.NotWritablePropertyExept ion: Invalid property 'myBean' of bean class .... :
Bean property 'myBean' is not writable or has an invalid setter method: Does the parametertype of the setter match the return type of the getter?

Any help/suggestions truly appreciated.

Thanks
Jonny

Well what does your setter look like?

[Costin Leau]

Normally your setter and getter should address the same type, i.e.:

SomeClass myBean;

public SomeClass getMyBean() { ... };
public void setMyBean(SomeClass otherBean) { ... };

Hi,

somehow I don't get this error. My POJO seems to be alright.

The class:

package de.fhkempten.webedi.cocoon.portal.model.sap;


/**
 * Sairport generated by hbm2java
 */
public class Sairport  implements java.io.Serializable {

    // Fields    

 private java.lang.String Id;
 private java.lang.String Name;
 private java.lang.String City;
 private java.lang.String Country;
 private java.lang.String Utc;


    // Constructors

    /** default constructor */
    public Sairport() {
    }
    
    /** constructor with id */
    public Sairport(java.lang.String Id) {
        this.Id = Id;
    }
   
    // Property accessors
    /**
    
    */
    
    public java.lang.String getId () {
        return this.Id;
    }
    
   public void setId (java.lang.String Id) {
        this.Id = Id;
    }
    /**
    
    */
    
    public java.lang.String getName () {
        return this.Name;
    }
    
   public void setName (java.lang.String Name) {
        this.Name = Name;
    }
    /**
    
    */
    
    public java.lang.String getCity () {
        return this.City;
    }
    
   public void setCity (java.lang.String City) {
        this.City = City;
    }
    /**
    
    */
    
    public java.lang.String getCountry () {
        return this.Country;
    }
    
   public void setCountry (java.lang.String Country) {
        this.Country = Country;
    }
 /**
    
    */
    
    public java.lang.String getUtc () {
        return this.Utc;
    }
    
   public void setUtc (java.lang.String Utc) {
        this.Utc = Utc;
    }

}

The error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'petStoreServiceTarget' defined in class path resource [de/fhkempten/webedi/cocoon/portal/spring/applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'sairportDAO' of bean class [de.fhkempten.webedi.cocoon.portal.spring.service.PetStoreServiceImpl]: Bean property 'sairportDAO' is not writable or has an invalid setter method: Does the parameter type of the setter match the return type of the getter?

Or did I understand you guys wrong, that the error was probably in the POJO?

Thanks
Jonny

You posted the wrong class. The error is caused by the fact that you are trying to wire the property sairportDAO on class PetStoreServiceImpl which does not has such a property.

Hi,

thanks to all for your help. I was looking for the eror in the POJO class all the time. I totally forgot the setter for my bean in PetStoreServiceImpl. Now it works fine.

Cheers

Hi,

I have a similar issue but it doesn't have anything to do with any of my class. I upgraded from 2.5 to 2.5.6 and I get this error on an application that used to work just fine.

Any thoughts?

thusi02, I have a similar issue to yours . . . did you ever find a resolution?

[criss]

you forget setter and getter in your service for dao object

[Hetal B]

Same issue will be faced incase your setter method is static. I faced the same issue and found the setter was static.
