I have an Action class and a Data class like below

Action Class

public class TestAction extends ActionSupport{

        private Data aData;
}

Data class

public class Data {
  private char v1;
  private char v2; etc till 17;
  public accessors for all variables above;

}

My jsp is like below

JSP snippet

<s:set var="varName" value="'data.v'"/>    
<s:iterator var="idx" begin="1" end="17">
      <s:set var="prop" value="#varName+#idx"/>
      <s:property value="<WHAT TO DO HERE TO GET THE VALUES STORED IN THE VARIABLES>"
</s:iterator

Whatever I put in the s:property tag's value attribute, (%{#prop}, #arr#prop, [prop]), I get the literal Strings data.v1, data.v2, ... data.v17 in my output and NOT the values stored in the data.v1, data.v2, etc. variables.

Can you please let me know how I can get the values stored in the data object.

Edit based on duplicate question suggestion struts-2-warning-the-default-value-expression-contains-evaluated-to-nullnu

The suggested question is a double evaluation of the value in the variable, whereas what I am looking for is a double evaluation of the variable. After submitting my original question, I came across another question with a comment that the double evaluation I am looking for is not supported. I have mentioned this as a comment in my own question, requesting for confirmation as it was not quite clear in the other question as well.

  • I was looking further in SO and found this question https://stackoverflow.com/questions/21498035/struts2-get-property-with-dynamic-value-in-jsp where @davenewton says double-evaluation is not possible. I am thinking mine too is the same case. Can someone confirm please. – Krishnaraj V Oct 04 '22 at 16:11
