Bean Initialization fails... Why?

[Phoenix Kilimba]

Dear Sirs et Madames,
am new to Spring unfortunately and have just added a bean locationVO to my application context. However, When deployed and I start up Tomcat 6, I get an exception:

  15:05:20,640 ERROR org.springframework.web.context.ContextLoader:208 - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'locationVO' defined in file [C:\apache-tomcat-6.0.18\apache-tomcat-6.0.18\webapps\hdss-x\WEB-INF\classes\META-INF\spring\applicationContext.xml]: Initialization of bean failed; nested exception is java.lang.UnsupportedOperationException: Only HttpServletRequest supported
        at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:519)
        at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:450)...  

My applicationContext.xml looks like so (relevant beans only):

 

        <bean id="locationVO" class="is.vo.LocationVO">
            <property name="locationCrudImpl" ref="locationCrud" />
        </bean>

        <bean id="locationCrud" parent="baseCrud" class="is.webui.LocationCrudImpl">
	<constructor-arg value="is.model.Location" />
	<property name="dao" ref="locationDao" />
	<property name="converter" ref="locationConverter" />
       </bean>   
     
       <bean id="locationDao" parent="baseDao">
	<constructor-arg value="is.model.Location" />
       </bean>

       <bean id="locationConverter" class="is.webui.cvt.EntityConverterImpl">
	<constructor-arg ref="locationDao" />
	<constructor-arg value="is.model.Location" />
	<constructor-arg value="java.lang.String" />
       </bean>
  

LocationVO looks thus:

  @Transactional
public class LocationVO {

    private Location location;
    private Long id;
    private String extId;
    String locationNo;
    FieldWorker fieldWorker;
    String region;

    public String getRegion() {
        return region;
    }

    public void setRegion(String region) {
        this.region = region;
    }......
  

Please help... What does the error message mean? google did not seem to be helpful ...
Thanks in advance

Hi,

In "locationVO" you have properties as follows:

    private Location location;  
     private Long id;  
     private String extId;  
     String locationNo;  
     FieldWorker fieldWorker;  
     String region;   

while in the config - file you have configured locationVO bean as follows:

<bean id="locationVO" class="is.vo.LocationVO">  
             <property name="locationCrudImpl" ref="locationCrud" />  
</bean> 

I don't see any property with the name of locationCrudImpl which you are referring to.

[Phoenix Kilimba]

Sorry the clas LocationVO DOES have that property, I was just a little careless when copy and pasting... its like so:

 
@Transactional
public class LocationVO {

    private Location location;
    private Long id;
    private String extId;
    String locationNo;
    FieldWorker fieldWorker;
    String region;


    /*
     * Next 3 fields are to store values selected via the drop-down
     * menus in Locations create.xhtml
     */
    Integer district;
    Integer village;
    Integer hamlet;
    Calendar entryDate;
    DataStatus status;
    Long locationTypeId;
    List<Location> locationList;
    SelectItem[] locationItems;
    String parentUuid;
    LocationCrudImpl locationCrudImpl;

    public LocationVO() {
    }

    public String getRegion() {
        return region;
    }

    public void setRegion(String region) {
        this.region = region;
    }....
}

Thanks again

Are you using autowire by name?

[Phoenix Kilimba]

Hi David,
Well am a bit new to Spring, and it is not my code, its code I have inherited, where would I check if the code IS using autowire by name? and What are the implications if it is?

[Alaa Nassef]

can you please post the full stack trace
