Hi,
I just wanted to know if it is possible to have multiple s:form in one
jsp. Each of the forms submit to a diffrent action.

The problem I faced is that. If I place multiple forms in one jsp. The
initials forms closing tags are commented out when the tag is rendered.
Is this expected behaviour or is it a bug.

Thanks in advance.

I can't reproduce this; I have many pages with multiple forms.

Including a source code snippet might be helpful.

The commenting effect is something one of the browsers does when viewing
invalid html (forget which browser). It comments out the html for nodes
that were impossible to include in the DOM. I've seen it when forms are
accidentally nested as the OP must have done.

Oh, interesting; I've never seen that.

This, of course, leads to the obvious conclusion that my HTML is always
perfect.

On a related note, watch for my auction of my bridge on e-bay Real Soon Now

Depending on the browser this may or may not have the full pathname.

In addition to the other suggestions posted you can also call the request's
isValidSessionId() method (or something like that).

One way is to the "status" attribute to your <s:iterator...> tag and use it
in your <s:textfield.../> tag as part of the name:

<s:iterator value="imports" status="stat">
<s:textfield name="name[%{#stat.index}]"/>
</s:iterator>

that as the index in your <s:textfield.../>'s name value. (The syntax may be
a bit off, but that's the idea.)

Hi all,

   In my JSP, i have three submit buttons, i want to know which button
user has clicked.

I tried from this site,
http://struts.apache.org/2.x/docs/html-form-buttons-howto.html
http://struts.apache.org/2.x/docs/html-form-buttons-howto.html
It's not working.

       Give me some ideas, i have added my code,


   public String execute() {
    if (buttonOnePressed) {
       message = "You pressed the first button";
      Save();
     
    } else if (buttonTwoPressed) {
       Update();
       message = "You pressed the second button";
    }

    else if (buttonThreePressed) {
      Show();
       message = "You pressed the second button";
    }
    else {
       return ERROR;
    }
    return SUCCESS;
  }

In My Struts.xml file,

<action name="user_details2" class="com.user_details">
       <result name="input">/JSP/user_details.jsp</result>
     <result name="success">/JSP/user_details.jsp</result>
     <result name="error">/JSP/user_details.jsp</result>
     
   </action>

In Jsp,

<input type="submit" name="buttonOnePressed" value="Save"/>
<input type="submit" name="buttonTwoPressed" value="Update"/>
<input type="submit" name="buttonThreePressed" value="Show"/>

Hi,

You can use
<s:submit value="Save" method="save"/>
<s:submit value="Update" method="update"/>
<s:submit value="Show" method="show"/>

and Action class with three methods, the same like execute()

Just make sure they're not nested inside one another, and that no two
elements on the rendered page have the same id attribute.

-Dale

I use wildcard mappings and Spring integration.
When a bad url is entered, no Spring bean is mapped and it results in an
exception page. I would like to swap this to a nice "Sorry, this page does
not exist" message.

However, the Exception Interceptor does not catch this, probably because it
happens before the chain of interceptors.
How can I solve this?

Hello

I have a S2 action working perfectly fine. But on one page of my web
App I would like the user to be able to download report in Excel. We
have this functionality in other pages as well but they arent using S2
and are doing this via a custom servlet which has doGet doPost and
processRequest methods.

Inside the processRequest..they do bunch of stuff to get the excel
read and in the end do this:

  ServletOutputStream stream = null;
  String fileName = \"something\";


     response.addHeader(\"Content-Disposition\", \"attachment;
filename=\" + fileName);
     response.setContentType(\"application/vnd.ms-excel\");
     stream = response.getOutputStream();
     wb.write(stream);

this is a void method.

My question is, since in my case I already have a S2 action..I dont
want to make a new servlet to do this.

How can i do the same in my execute method for S2?? what should the
execute method return? because when user clicks get Excel link..the
page stays the same but just the user is presented with open/save
dialog.

Woudl appreciate any help.

You can do this by creating a custom result type.

A example of a custom result type for streaming images from a action to
a img tag is here.

http://struts.apache.org/2.x/docs/how-can-we-display-dynamic-or-static-images-that-can-be-provided-as-an-array-of-bytes.html

You can use this as a example, but will probably have to have a modify
it slightly so that your action will have a getter and setter to pass a
output stream to the result type. In the result type you can write the
output stream to the response output stream.

I was trying stuff out and i hve got it working perfectly.

Only thing is my that my execute is returning a SUCCESS when
everything is done. However I do not have any <result> in my
struts.xml for this action. since the user shouldnt be moved to
another page.

Now I am able to see open /save dialog box as well and excel opens
fine too but in my logs i ssee the following exception..


StandardWrapperValve[default]: Servlet.service() for servlet default
threw exception
java.lang.IllegalStateException

just read the link you sent.

I cant make my execute method void because it is being used for
another page which requires it to send something back. :(

Mike Jennings wrote:

Or you can use a result type that's already provided that does exactly
what you need.

What the browser does with the data (attempt to display it/save it) is
determined by the "contentDisposition" You want that to read something
like: "attachment;filename=${something.dynamic}.xls"

bhaarat Sharma wrote:

As always, it should return the name of the appropriate result (in this
case, the name of the result of type "stream").

-Dale

I think its better if i post some code.

This is the action mapping for
 <action name=\"accessRequestReportResult\"
class=\"action.reports.AccessRequestReportResult\">
  <result name=\"showReport\">/useradmin/AccessRequestReport.jsp</result>
  <result name=\"failure\">login.jsp</result>
  <result></result><!--i was trying this but didnt work-->
 </action>


this is my execute method:


  public String execute() throws IOException, ServletException {

    //we dont enter here for excel
     if (getServletRequest().getParameter(\"isExcel\")==null)
    {
       setData(getActionValue());
       return \"showReport\";
    }
   //enter here for excel
    else
    {
       setData(getServletRequest().getParameter(\"action\"));
       excelReport();//this does all the excel stuff and writes
to the HttpServletResponse.
       return \"stream\";//i also tried return SUCCESS but even
then got illegalStateException
    }

  }

Everything works dandy but i have an IllegalStateException in my logs.
saying no result defined for \"stream\"...

is there a workaround here...:(

Thanks for that. that gives me a better idea to go about things + i
didnt know we can call methods from struts.xml


i implemented this but am getting this error

java.lang.ClassCastException: org.apache.coyote.tomcat5.CoyoteOutputStream
 org.apache.struts2.dispatcher.StreamResult.doExecute (StreamResult.java:182)
 org.apache.struts2.dispatcher.StrutsResultSupport.execute (StrutsResultSupport.java:178)
 com.opensymphony.xwork2.DefaultActionInvocation.executeResult (DefaultActionInvocation.java:348)
 com.opensymphony.xwork2.DefaultActionInvocation.invoke (DefaultActionInvocation.java:253)



my getExcelStream looks like this

  public ServletOutputStream getExcelStream()
  {
    return this.stream;
  }

excelDownload method has this that sets up the stream.
     stream = response.getOutputStream();
     wb.write(stream);

wb is the worksheet...

http://struts.apache.org/2.x/struts2-core/apidocs/org/apache/struts2/dispatcher/StreamResult.html

describes how that result works, stating taht the "inputName" parameter
is "the name of the InputStream property from the chained action
(default = inputStream)"

The filename expression works because this result extends
http://struts.apache.org/2.x/struts2-core/apidocs/org/apache/struts2/dispatcher/StrutsResultSupport.html
which allows for ognl expressions in result parameters (if the parse
parameter is true, which is the default).

That's saying that it can't cast a "CoyoteOutputStream" as an
InputStream. The result will manage the output to the client. You
shouldn't need to deal with the response or the servlet. What you need
to do is provide the result with a source of the data to be sent to the
client.

Note that every call to getExcelStream needs to return an independent
InputStream. For example, when you don't tell the result the
contentLength it has no choice but to step through the entire stream to
find the length, then it'll ask for a new stream to actually pull the
data out of to send to the client.

-Dale

>What you need to do is provide the result with a source of the >data

and that data has to be in java.io.InputStream??

even if my getExcelStream method returns java.io.OutputStream...I
still get an exception

so what TYPE of data should getExcelStream be returning :(

seems i am so close to fixing this....

An InputStream is a source of data.
An OutputStream is a destination for data.

> still get an exception

Because the result can't read() from an OutputStream.

> so what TYPE of data should getExcelStream be returning :(

It should be returning something that extends InputStream.

I don't think your workbook method is doing what you think it's doing.
It might make sense if it took an output stream as a parameter, like
wb.write(outputStream), but if it is returning an output stream then
it's really asking for input...

We're using Struts 1.2.9 and the problem we're seeing is that if a user
tries to upload a file that does not exist or upload a file that exceeds
the maxFileSize attribute the FormFile object on the ActionForm is null
and so we cannot distinguish between the two.

We thought about removing the maxFileSize parameter and doing the check
ourselves in the ActionForm, but it appears that the file upload has
already begun at that point and while we can look at the Content-Length
header from the HttpServletRequest object in the Struts Action, it's a
moot step because the file has already begun to upload.

Is there a method on Action or DispatchAction (or perhaps something
else) that we can override to prevent the file upload if it exceeds a
size we determine? My concern is that Apache commons-fileupload gets
the request to upload the file first before Struts gets it and we might
be hozed in this regard.

Any thoughts? Thanks.

I have a dynamic multi line collection of dates with a date converter doing its job perfectly - populating dates or reporting conversion errors by field as it should.

What I'm wondering is if it's possible to dynamically reference these fields without providing individually fixed definitions for each possible field.

For example, I can define each named field as follows:
<field name="account.userRoles[0].startDate">
<field-validator type="conversion">
  <param name="repopulateField">true</param>
  <message>${getText("errors.invalid.date")}</message>
</field-validator>
</field>

<field name="account.userRoles[1].startDate">
<field-validator type="conversion">
  <param name="repopulateField">true</param>
  <message>${getText("errors.invalid.date")}</message>
</field-validator>
</field>

etc.

This approach does work. However, I'd prefer have a single definition perhaps using a wildcard/regex since I don't know how many fields the user will submit.

Is it possible to substitute some kind of wildcard or regex here?

Thanks,
Grant
