i tried everywhere couldnt find the reason ..if anybody knows pls let me know what i am doing wrong..
Thank you in advance

[Eugene Abarquez]

You should populate your <f:selectItems> with objects of type SelectItem and not String[]. So for instance your property instanceRole should not be of type String[], but of type SelectItem, which is usually placed inside a List (as it is <f:selectItems> and not <f:selectItem>).

In your bean, you should have something like this:

public class InstanceBean {
 
private ArrayList instanceRole;
...
 
public ArrayList getInstanceRole() {
instanceRole.add(new SelectItem("", "Select Instance Role"));
instanceRole.add(new SelectItem("Value 1", "Value 1"));
return instanceRole;
}
 
}    

You can seperate the part that loads the values into your List in a seperate method, like loadInstanceRole(), as I usually do, but its up to you.

Hope this helps.

i dont know what to do ..thank you very much for replying

[Bauke Scholtz]

The SelectItem value type must correspond with the valuebinding of the h:selectOneMenu.

public List getSelectItems() {
    List selectItems = new ArrayList();
    selectItems.add(new SelectItem("value1", "label1");    
    selectItems.add(new SelectItem("value2", "label2");    
    selectItems.add(new SelectItem("value3", "label3");    
    return selectItems;
}
 
public String getSelectedItem() {
    return selectedItem;
}
 
public void setSelectedItem(String selectedItem) {
    this.selectedItem = selectedItem;
}

If you use any other object instead of the String "value", then the selectedItem setter/getter type must correspond with it. You can use any object in it. The label have to be a String all the time anyway.

can anyone pls help in finding whatz wrong now ..
thankx in advance

[Eugene Abarquez]

Make sure you have included all the necessary jsf jars in your lib folder.

[akshatha bhatt]

yeah all the jar files are there in
Test Libraries
Libraries
WEB-INF/lib

[Eugene Abarquez]

Then it should work. Just double check evreything. I think this might be a configuration issue. Check your web.xml if you added all the necessary jsf servlet mappings, if you've added all the jsf jars in your build path, etc ...

Regards,

[akshatha bhatt]

these are the jar that are there

jsf-facelets.jar
jsf-impl.jar
jsf-api.jar
jsf-impl.jar
common-logging.jar
common-beanutil.jar
common-collections.jar
common-digester.jar
jstl-standard.jar
jstl.jar
log4j.jar
el-ri.jar
el-api.jar

here is faces-config.xml
<faces-config>
<managed-bean>
<managed-bean-name>InstanceBean</managed-bean-name>
<managed-bean-class>com.InstanceBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
</faces-config>

i really dont know whatz wrong .. i'm using Netbean& sun app server .. is there somthing i should change.
Thank you very much for your reply

[Eugene Abarquez]

Your web.xml should have something like this:

  <?xml version="1.0"?>
 
<!DOCTYPE web-app PUBLIC
   "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
   "http://java.sun.com/dtd/web-app_2_3.dtd">
 
<web-app>

<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>

</servlet>

<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>

</web-app>
  

[akshatha bhatt]

this is what i have web.xml

The import org.apache.log4j cannot be resolved
SelectItem cannot be resolved to a type
SelectItem cannot be resolved to a type
SelectItem cannot be resolved to a type
SelectItem cannot be resolved to a type

Looks to me like a classpath issue. Delete all your class files and do a clean build.
