Simple Struts Q.......??

pbarry · 02-05-2005 5:56pm #1

I know this seems like a braindead Q but my head is melted.....

I want to populate a form with user details taken from DB. My jsp page can find the bean but I can't seem to put the info into the relevent html text boxes.

Any ideas??

<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<html> 
	<head>
		<meta name = "Generator" content = "Easy Struts Xslt generator for Eclipse (http://easystruts.sf.net).">

		<title>ViewPoint</title>
	</head>
	<body>

	<logic:present name="userName" scope="request">

		<div align="center"><html:form action="/editprofile" onsubmit="return validateEditprofileForm(this);">			
  
		  <table width="424" border="0">
            <tr>
              <td width="170">Username : </td>
              <td width="100"><html:text property="userName"><bean:write name="userName" scope="request"/></html:text></td>
              <td width="100"></td>
            </tr>
            <tr>

etc

etc

etc

check the bean that is associated with the action. The bean has to have the a bean pattern matching the elements in the form.

for example: getUsername()/setUsername() as the pattern therefore the property in the form would be username.

Best not to use mixed casing in property name it gets very confusing.

About retreving details from a DB, you can use the SetupAction to get information from a DB then an updateAction to write to the DB.

Follow the examples at http://www.reumann.net/struts/main.do.

Hey,

Im fine up to the point of populating the text fields.

I can print the userName on the page by using

<logic:present name="userName" scope="request"><bean:write name="userName" scope="request"/> </logic:present>

I can iterate through a list using

<logic:iterate etc...........

BUT I can't seem to be able to set the text of a text field. I've tried

<html:text property="userName" value="'<%=request.getParameter("userName")%>'">

Any ideas....??

Hmmm, that's a good one.

Basically, if the form attached to the action has the property set in it (for example: username).

Then in form, I have a <html:text property="username"/> I get the property I am looking for.

Try using less of the struts tag, some of them are deprecated anyway.

seagizmo,

Apologies for not catchin on quicker, bit slow after a long wkend of boozin,

got it working. I wasn't setting the 'user' bean to the request properly. That explains the errors..............

cheers!
