Hi, I have a JSP page that outputs data using a Collection using the following section
<logic:iterate id="lifeBenefit" name="lifeBenefits" type="com.quote.dao.BenefitLineItem" indexId="classNum"> <tr valign="middle" class="bg2"> <td height="28" bgcolor="#FFFFFF"> <table border="0" cellspacing="0" cellpadding="0"> <tr> <td> <html:checkbox name="lifeBenefit" property="benClsTtl" indexed="true"></html:checkbox> </td> <td class="formtext"> <%=i %></td> <% i++; %> </tr> </table> </td> </tr> The above JSP is converted into the following HTML code <table border="0" cellspacing="0" cellpadding="0"> <tr> <td> <input type="text" name="lifeBenefit[0].benClsTtl" size="17" value="some EMPLOYEES"> </td> </tr> I am having a problem writing the corresponding ActionForm, the problem is how do I declare the variables to capture the values entered by the user I have attempted to write it and here is what I came up with public class GotoStep4Form extends ValidatorForm implements Serializable { private ArrayList records = null; private BenefitLineItem [] lifeBenefits; private String [] benClsTtl; public ActionErrors validate( ActionMapping mapping, HttpServletRequest request) { ActionErrors errors = super.validate(mapping, request); if(errors == null) errors = new ActionErrors(); if (!errors.empty() ) { HttpSession session = request.getSession(); } return errors; } public BenefitLineItem getLifeBenefit(int index) { while(index >=records.size() ){ this.records.add(new BenefitLineItem()); } return (BenefitLineItem) records.get(index); } /** * Gets the benClsTtl * @return Returns a String[] */ public String[] getBenClsTtl() { return benClsTtl; } /** * Sets the benClsTtl * @param benClsTtl The benClsTtl to set */ public void setBenClsTtl(String[] benClsTtl) { this.benClsTtl = benClsTtl; } /** * Sets the lifeBenefit * @param lifeBenefit The lifeBenefit to set */ public void setLifeBenefit(int index, BenefitLineItem lifeBenefit) { this.lifeBenefits[index] = lifeBenefit; } public BenefitLineItem[] getLifeBenefits() { return lifeBenefits; } public void setLifeBenefits( BenefitLineItem[] v) { lifeBenefits = v; } } The above gives me an error : WebGroup X Servlet Error: BeanUtils.populate: java.lang.reflect.InvocationTargetException: java.lang.NullPointerException at com.fdl.quoteweb.actionforms.GotoStep4Form.getLifeBenefit(GotoStep4Form.java:53) at java.lang.reflect.Method.invoke(Native Method) at org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.java:475) at org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.java:410) at org.apache.commons.beanutils.PropertyUtils.getNestedProperty(PropertyUtils.java:749) at org.apache.commons.beanutils.PropertyUtils.getProperty(PropertyUtils.java:780) at org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:793) at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:726) at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:978) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:779) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:246) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1292) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:510) What am I doing Wrong? How dow I define the variables in the ActionForm to have Struts populate the data in the form? Any help will be appreciated.
