Passing values to action form in struts using html:link tag in struts

hi
As we can post values to action form bean in struts using a <html:text> tag in side a form.
Can the same be achieved by using a html:link attribute.
If not then how can this be achieved (i.e. posting a form on click of a link and populating action form bean property for the same).
thanx in advance.

html:option tag in STRUTS

How can I put a "selected" attribute in the <html:option> tag in STRUTS? In regular HTML, I can say:
<select name="test">
<option name="opt1" selected>Option 1</option>
</selected>
But I can't use the "selected" key word in the STRUTS tag:
<html:select property="myList">
<logic:equal name="myListElement" value="Hello World">
<html:option value="opt1" selected>Option 1</html:option>
</logic:equal>
<logic:notEqual name="myListElement" value="Hello World">
<html:option value="other opts">Other opts</html:option>
</logic:notEqual>
</html:select>
How can I get the following to work?
Thanks,
Dylan

Regular Expression to convert URI to HTML link tag

I'm trying to create a method that takes an input string and converts any URIs found in the string to a html link tag.
For example,
String input = "This is a test string. I like http://www.sun.com/ and think you should check out http://java.sun.com/"; The output should contain an html a tag for each URI and use the URI as the text as well.
I need this for a blogging web app i'm working on.
I tried a few things like
import java.util.regex.*;
import java.text.*;
public class test
     public static void main(String[] args)
          final Pattern p = Pattern.compile("(\\sI\\n|^)(\\w+://[^\\s\\n]+)");
        final Matcher m = p.matcher(args[0]);
          System.out.println(args[0]);
          args[0] = m.replaceAll( "$1<a href=\"$2\">$2</a>");
          System.out.println(args[0]);
}Any ideas? Something like this will match "http://www.apple.com/" but not a complex string. I've googled this quite a bit and I'm not very good with regular expressions.

Couldn't get your posted regex to work on anything. Try this:public static void main(String[] args) {
    String input = "This is a test string. I like http://www.sun.com/ and think you should check out http://java.sun.com/";
    final Pattern p = Pattern.compile("(\\s|^)(\\w+://\\S+)(\\s|$)");
    final Matcher m = p.matcher(input);
    input = m.replaceAll("$1<a href=\"$2\">$2</a>$3");
    System.out.println(input);
}It should match any uri, however I recommend replacing \\w+ with a more concrete string like (?:(?:http)|(?:https)|(?:ftp)). Let me know if you have a uri that it doesn't match.

Problem with html:select or html:options tags using struts,jsp and tomcat

Hi
I'm updating a Struts-Project to a new layout and therefore rework all jsp Sites.
I'm also using a new Folder-Structure and update therefore my struts-config file.
My Problem now is:
Till now, we had a select-field with a code like this:
< html:form action="/timetableAction" method="POST">
< table width="53%" border="0">
< tr>
< td>< html:radio property="dauer" value="semester"
/></ td>
< html:select property="semester" size="1">
< htmlptions name="semesterList" />
</ html:select>
</ html:form>
The problem now is, that whenever I use any <html:xy> tag, the tomcat server I use can not show the page, he shows just the headers of the template, but not the
content.-jsp-File where the form would be in. He stops right in the middle of the html page, when he notices the <html:xy> tags.
And the funny thing is, that he has no problem to show a page when there is a <html:errors> within it? Why could this be? the struts-html.tld File is well included and teh Tomcat Server shows no exceptions.
Waiting for you answers and thanks

Thank you, I already got the answer in another forum

Having problems passing more than one parameter with html:link tag

Hi guys,
for my web application I�m using Struts. I�ve got a database with user details. I would like to get users list and link to the details of each user. I wrote the code and everything is working fine only the users list is repeating as many times as users in the list.
For ex: I have in the database User1, User2 and User3. I would like to have a result like:
User1
User2
User3
Instead of it I have the result like:
User1
User2
User3
User1
User2
User3
User1
User2
User3
What I�m doing wrong? Could somebody help me please?
Thank you in advance
There is a snippet of the code, which I�m using in jsp:
<code>
<logic:iterate id="root" name="user">
               <%
                    java.util.HashMap users = new java.util.HashMap();
                    params.put("user",root);
                    pageContext.setAttribute("usersName", users);
               %>
               <html:link name=" usersName " scope="page" page="/name.do">
                    <logic:iterate id="folder" name="user">
                         <bean:write name="folder" /><br>
                    </logic:iterate>
               </html:link><br>
               </logic:iterate>
</code>

Suggestion: next time you post code use the "CODE" button to put code tags around it. It formats much nicer that way :-)
You have a nested loop structure here.
<logic:iterate id="root" name="user">
<%
    java.util.HashMap users = new java.util.HashMap();
    params.put("user",root);
    pageContext.setAttribute("usersName", users);
%>
<html:link name=" usersName " scope="page" page="/name.do">
    <logic:iterate id="folder" name="user">
      <bean:write name="folder" /><br>
    </logic:iterate>
</html:link><br>
</logic:iterate>Both loops iterate over your "user".
Your first loop loops over each user.
Then your second loop also loops over each user - hence you get number of users * number of users = 3 groups of 3.
If you have 4 users, you would have 4 groups of 4.
I only see you setting one parameter: "usersName" What other parameters do you need to pass?
At a guess, the inner loop is unnecessary, and you want to write the users name as the text for the link, and also use it as a link parameter.
<logic:iterate id="root" name="user">
<%
    java.util.HashMap users = new java.util.HashMap();
    params.put("user",root);
    pageContext.setAttribute("usersName", users);
%>
<html:link name="usersName" scope="page" page="/name.do">
      <bean:write name="user" /><br>
</html:link><br>
</logic:iterate>

Struts - HTML:link tag with dynamic page attribute?

I am trying to use the html:link but the page value is dynamic (resulting from the bean within the iterate tag). The code below doesn't work - error. Is there a way to use all Struts tags and make this happen. Any ideas?
        <logic:iterate id="myMenuForm" property="menuItem" scope="session" name="menuForm" >          <html:link page="<bean:write name="myMenuForm" property="menuDisplayName"/>">                  <bean:write name="myMenuForm" property="menuDisplayName"/>          </html:link>        </logic:iterate> Thanks,
mlv

Thanks for all your help. Based on all you your comments, it is now working
and I thought I would provide some details about how I got it working.
There are not that many examples within the Struts documentation.
id = unique name for the object that can be referenced within the iterate
tag.
name = is the Bean, in this case it's the ActionForm, that contains the List
object that will be iterated. In my case, I have a ActionForm that contains
a List property that contains all the menu item rows from the databse.
property = is the property name within the ActionForm that is the List
object. Links to the getter method
Within the <bean:write> tag you use the id name to get a handle on the final
object from the iterate tag and the property is one of the property values
within the bean that is contained within the List.
So in this case I have a ActionForm bean that contains a List property that
contains a collection of beans.
FormAction - bean
property menuItems of type List contains:
- row 1 = bean (with a property of menuDisplayName)
- row 2 = bean (with a property of menuDisplayName)
- row 3 = bean (with a property of menuDisplayName)
Here's the JSP code for the tag.
        <logic:iterate id="myMenuForm" name="menuForm" property="menuItem" >
          <html:link page="www.yahoo.com"/>
                  <bean:write name="myMenuForm" property="menuDisplayName"/>
          </html:link>
        </logic:iterate>Now I would like to make the <html:link> page attribute value dynamic from
the iterate bean. Therefore, you can make the url for the link dynamic If
you know how to do that, please feel free to provide some help.

Problem with html link in my jsp----Not showing

Hii frnd ,i m trying to put a <hhtml:link> tag in my jsp ,
the tag is not showing up.
Wht can be the possible reason for tht.

You would probably increase the chances of getting a reply if you posted the code you use. There could be a hundred different reasons.

Html:link and javascript

Maybe I'm asking the wrong question, how do you execute JavaScript within a <html:link> tag in Struts. I simply want to execute a collapse / expand divs with an onclick attribute in the <html:link> tag.
Can this be done with some other tag?
TC

and why didnt u try putting the onlick tag ?
<html:link href=# onClick="myJSfunction()">Rohit</html:link>

Jsf equivelent of struts html:base tag

I'm having an issue with the myfaces panelNavigation component. I'm including it in a series of pages with subview & jsp:include tags. It's working great with one exception. If I browse to a document one directory deeper than the "home" page, and then click the "home" link taking me back to the parent directory, the external css sheet doesn't load. All of my links and text are there, but not styled at all. If I click the link again, every thing loads fine.
I remember the <html:base> tag from struts and I tried using it on the home page. However, the page refused to load and the server did not throw a stack trace (even though the logging is set to FINE).
I'm wondering if anyone else has experienced a similar issue and if there is an equivelent tag in JSF to solve this problem.
Thanks!

thanks for you answer.
but when i use the <html:base/> tag, everybody can see my internal structure when viewing the source code of the generated html in browser.
i think i haven't understood the base tag (and have never used it).
could somebody tell me how to use this tag correctly ? (html or struts version)
actually my problem is, i used to define a variable at the top of every jsp page like this :
<%! String conPath ; %>
<% conPath = request.getContextPath();%>
then,
<a href="<%= conPath%>/some/link">Some Text</a> or <img src="<%=conPath%>/image/bottom.jpg">, is there a better way without using java code in jsp ? because when the context root changes some day, i have to change all jsp pages.
can the <base> tag be helpful here ? how ?
yawmark,
when i put all my jsp files under WEB-INF, do i have to change something in struts-config.xml ?
thanks in advance

html:link problem with Mozilla vs. IE

Hello,
I am experiencing the following situation.
In IE the following segment of code works properly:
<td>
<table border="0" align="center" cellpadding="0" cellspacing="0">
<tr>
     <html-el:link action="zone3/g036Play">
     <td><html-el:img srcKey="detailsLeft2" bundle="ZONE3_IMAGE_RESOURCE_KEY" border="0" width="17" height="18"/></td>
     <td class="details"><bean-el:message key="couponsHistory.details" bundle="XLTS_MESSAGE_RESOURCE_KEY"/></td>
     <td><html-el:img srcKey="detailsRight2" bundle="ZONE3_IMAGE_RESOURCE_KEY" border="0" width="9" height="18"/></td>
     </html-el:link>
</tr>
</table>
</td>BUT in Mozilla the link doesn't work
On the other hand, i found out that if i place the <html:link> tag outside of the table, then the link will work properly for mozilla but won't work for IE.
Is there a way i can work this problem around?
Thank you very much in advance.
Frini

ok, sorry, my mistake, i was looking at the wrong fragment of code.
It output the HTML code:
   <td><a href="/XltsWeb/zone3/g036Play.web"><img src="images/xlts/details_left_lottery.gif" height="18" width="17" border="0"></td>
   <td class="details">Details</td>
   <td><img src="images/xlts/details_right1_lottery.gif" height="18" width="9" border="0"></a></td>which still doesn't work in Mozilla as a link...
But if i place <html:link> outside the table and inside TD, i get:
<td>
<a href="/XltsWeb/zone3/g036Play.web"><table border="0" align="center" cellpadding="0" cellspacing="0">
<tr>
<td>
   <td><img src="images/xlts/details_left2_lottery.gif" height="18" width="17" border="0"></td>
   <td class="details">Details</td>
   <td><img src="images/xlts/details_right2_lottery.gif" height="18" width="9" border="0"></td>
   </td>
   </tr>
   </table></a>
</td>and works in Mozilla, BUT no, none of the above works in IE!!!!!!!!!!!!!!!!!!!!!
The only code that works in IE, is the first that i posted!!!!

How to use pdk-struts-html:link

i have a portlet,
<pdk-html:link href="/StartEhrpHrj.do?targetGroup=Hrj1030MInfDtlGroup">
xyz
</pdk-html:link> </td>
but no link,why

Hi,
It is not an issue with the tag. Look at the docs for the struts html:link tag; the pdk-html:link tag is intended to replace this tag and not the regular HTML anchor tag.
Good luck,

Html:link action html:link on results page null

I am sure that this is something simple and small but I have been banging my head against this problem for a while now.
I am using the <html:link> tag on my index.jsp page activates an action, retrieves a result and forwards to the homePage.jsp. The home page has a tiles layout and the results are actually in homePage_lowerLeftLevel.jsp within the homePage.jsp. Below the results I have an <html:link> tag which is identical to the tag in the index.jsp but now instead of seeing the link there is [ServletException in:/pages/homePage_leftLowerLevel.jsp] null' and if I go back to the index.jsp I get the following error�

It should be used something like this!!!
<html:link action="myStrutsAction" paramId="user" paramName="userName"/>if the userName attribute had the value "Bob" that would produce:

Html:link to c:url

<html:link action="/DispatchAddAction.do?method=Delete">
<fmt:message var="btnDelete" key="btn.delete" bundle="${appbundle}"/>
<c:out value="${btnDelete}"/>
</html:link>
this is working fine.
Trying now to use JSTL c:url
<c:url value="/DispatchAddAction.do" var="url">
<c:param name="method" value="Delete"/>
<fmt:message var="btnDelete" key="btn.delete" bundle="${appbundle}"/>
<c:out value="${btnDelete}"/>
</c:url>
I don't see the link Delete. What am I missing here?
Thanks.

The tags do slightly different things.
The html:link tag renders an anchor tag for a link on an HTML page.
The c:url tag just produces a url. It doesn't produce HTML. The struts html:rewrite tag would be closer to the function of c:url
As such you have to generate the link yourself:
// set up values
<fmt:message var="btnDelete" key="btn.delete" bundle="${appbundle}"/>
<c:url value="/DispatchAddAction.do" var="url">
<c:param name="method" value="Delete"/>
</c:url>
// then render the tag like this:
<a href="<c:out value="${url}"/>"><c:out value="${btnDelete}"/></a>
//if you have a JSP2.0 container you could do it just like this:
<a href="${url}"><fmt:message key="btn.delete" bundle="${appbundle}"/></a>Cheers,
