How to validate referenced bean property

[Hermann Maurer]

Hello,

referring to Struts 2. Tricky question.

Basically I know how to validate with annotations properties in the action class.
However I don't know how to validate properties of a bean which is referenced in the action class.

Hoping someone can let me know ...

Form.jsp and MyBean class are informational only, the question is how to put Validation into the ActionClass below for a referenced bean.


Form.jsp:

        <s:form action="dataform" method="POST" validate="true">

            <s:textfield label="Property in ActionClass" name="myInteger" size="20" maxlength="20" />
            <s:textfield label="Property of Bean in ActionClass" name="myBean.myInteger" size="20" maxlength="20" />
          

MyBean class:

  private int myInteger;
  
  public int getMyInteger() {
      return myInteger;
  }

  public void setMyInteger(int myInteger) {
      this.myInteger=myInteger;
  }

ActionClass:

  privat int myInteger;
  private MyBean myBean;

  public int getMyInteger() {
      return myInteger;
  }

 @IntRangeFieldValidator(message = "out of range", min = "0", max = "42")

  public void setMyInteger(int myInteger) {
      this.myInteger=myInteger;
  }


  public MyBean getMyBean() {
      return myBean;
  }

  <!--How can I validate myInteger Property within the MyBean bean? -->
  public void setMyBean(MyBean MyBean) {
      this.myBean=myBean;
  }

Many thanks,
Hermann
