Just to add another note, it may not work(you need to verify by looking at Java Bean spec) if you define your property name like xMLQueryString, but xmlQueryString will work.

I have a form that has a hidden field in it, I am not populating this hidden field on the page load but rather I am populating the value in a JavaScript function and then using the form.submit() in JavaScript to submit the form. When I try pulling the value for the hidden field out in my Action class I get either a null pointer exception or a zero length string depending on how I try to get the data. I have verified that there is data populating in the hidden fields value. Here is the code below, if anyone can help me in finding out how to get the value I would be very grateful. /////jsp//// <%@ page language ="java"%> <%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%> <%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%> <%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"%> <html> <head> <title>Report Generator</title> <LINK REL="stylesheet" TYPE="text/css" HREF="style/style.css"> <script LANGUAGE="JavaScript1.2" SRC="style/select.js"></script> <script LANGUAGE="JavaScript1.2" SRC="style/report_generator.js"></script> <script LANGUAGE="JavaScript1.2" SRC="style/dyn_select.js"></script> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000" leftmargin="0" topmargin="0"> <html:form action="Generator" name="generatorForm" type ="com.kcp.csi.reportgen.GeneratorForm"> <html:hidden property="XMLQueryString"/> <table width = "100%" border = "0" cellpadding="0" cellspacing="0"> <tr> <td align="left" valign="top"> <table width="197" border="0" height="103%" align="left" valign="top" cellpadding="0" cellspacing="0"> <tr> <td height="90%" width="193" background ="images/bg_home_03.gif" > <table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td align="left"> <br><html:img src="images/load.gif" onmouseover="runtimeStyle.cursor = 'hand'" onclick="runClick(document.generatorForm)"/> <br><br> <html:img onmouseover ="runtimeStyle.cursor = 'hand'" src="images/update.gif" onclick ="getHiddenValue(document.generatorForm)"/> <br> <br> <html:img onmouseover ="runtimeStyle.cursor = 'hand'" src="images/delete.gif"/> <br><br> <html:img onmouseover ="runtimeStyle.cursor = 'hand'" src="images/save.gif"/> <br><br> <html:text property ="saveName"/> </td> </tr> </table> </td> </tr> ..... and so on..... ////javascript//// function getHiddenValue(form) // added for testing { alert(form.XMLQueryString.value); } function runClick(form) { var strQueryXML = new String(); if(form.selectedColumns.options.length > 0) { strQueryXML = getQueryXML(form); form.XMLQueryString.value = strQueryXML; alert(strQueryXML); // added for testing alert(form.XMLQueryString.value); // added for testing form.submit(); } else { alert("Please select at least one column."); objSelCols.focus(); } } ////Action Class///// public class GeneratorAction extends Action { private ActionErrors errors = new ActionErrors(); public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { HttpSession session = request.getSession(); String sXML = new String(); String target = new String("failure"); if(form != null) { errors.clear(); GeneratorForm gForm = (GeneratorForm)form; try { //sXML = gForm.getXMLQueryString(); //0 length string sXML = request.getAttribute("XMLQueryString").toString(); //null pointer //sXML = session.getAttribute("XMLQueryString").toString(); //null pointer System.out.println("XML String ="+sXML.toString()); target = new String("success"); } catch(Exception e) { System.out.println("Error Getting Attributes "+e); errors.add(ActionErrors.GLOBAL_ERROR, new ActionError ("errors.dbsubmiterror",sXML)); target = new String("failure"); saveErrors(request,errors); } } return(mapping.findForward(target)); } } Thanks Tim Bachta Information Technology MC 48 -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
