RE: What is the best way to pass a parameter to a forward?
i found this class a while ago on this list it works great, just create a
parameter action forward and then add
params
forward.addParameter("name", "value");
return forward;
import java.util.HashMap;
import java.util.Iterator;
public final class ParameterActionForward extends ActionForward {
private static final String questionMark = "?";
private static final String ampersand = "&";
private static final String equals = "=";
private HashMap parameters = new HashMap();
private String path;
public ParameterActionForward(ActionForward forward) {
setName(forward.getName());
setPath(forward.getPath());
setRedirect(forward.getRedirect());
}
public void setPath(String path) {
this.path = path;
}
public String getPath() {
StringBuffer sb = new StringBuffer();
sb.append(path);
boolean firstTimeThrough = true;
if (parameters != null && !parameters.isEmpty()) {
sb.append(questionMark);
Iterator it = parameters.keySet()
.iterator();
while (it.hasNext()) {
String paramName = (String)it.next();
String paramValue = (String)parameters.get(paramName);
if (firstTimeThrough) {
firstTimeThrough = false;
} else {
sb.append(ampersand);
}
sb.append(paramName);
sb.append(equals);
sb.append(paramValue);
}
}
return sb.toString();
}
public void addParameter(String paramName, Object paramValue) {
addParameter(
paramName,
paramValue.toString());
}
public void addParameter(String paramName, String paramValue) {
parameters.put(paramName, paramValue);
}
}

What version of Struts are you using? It's not supposed to work, at least
with the latest code, so I'd like to find out whether we have a bug, or
you're using a version prior to the forwards being frozen.

Forgot to show the code how to use it!
In your action you should not return

but
Hashtable a = new Hashtable();//add what ever key/value pairs you need
return new
ActionForwardParameters().add(a).forward(mapping.findForward("success"))

It's funny that you say that it will not work, because it does for me,
and without throwing any exceptions.
That being said, your point about modifying an action mappings forwards
is a good one. It is unfortunate that the ActionForward class doesn't
have a copy constructor

Re: What is the best way to pass a parameter to a forward?
What you are doing will not work - at least, not the way you are doing it.
You are trying to modify the ActionForward instance that is owned by Struts,
and calling setPath() on that instance will result in an
IllegalStateException.
You need to create your own ActionForward instance, instead of trying to
modify Struts' one. You can do that with something like this:
ActionForward goto = mapping.findForward( "success" );
String path = ...; // Put together your new path
ActionForward myGoto = new ActionForward(path, goto.getRedirect());
return myGoto;

I'm trying to solve a problem, but I'm not sure my solution is the best
way. Basically, I want to set a parameter on a forward within the
action's execute.
I'm in my action's execute method. I've just successfully performed
some work, and I now want to forward/redirect to the next page. So,
I've got some code that looks like this:
public ActionForward execute(ActionMapping.) {
// do some work
ActionForward goto = mapping.findForward( "success" );
return goto;
}
With an action mapping that looks like this:
Basically, if I left the EntrySaveAction.execute do what's doing right
now, then upon successful completion, it would redirect to
"/Container.do". However, what I want it to do is redirect to
"/Container.do?id=45", where 45 is the id of the container that I want
to go to. The value of "45" is dynamic, and is know at the time of the
EntrySaveAction.execute command.
The way I'm currently doing it is something like this:
public ActionForward execute(ActionMapping.) {
// do some work
ActionForward goto = mapping.findForward( "success" );
String path = goto.getPath();
path += "?id=" + container.getId();
goto.setPath( path );
return goto;
}
Is this the correct way to do this? Is there a better way?
Thanks in advance

Re: What is the best way to pass a parameter to a forward?
Jay,
Since Struts does not differentiate between a POST and a GET, passing
data as query parameters is the same as form data. You could create a
form that has only the one field "id" which would be populated if you
called a URL of "/someAction?id=foo". This is what I use when I create
dynamic links. This is when I want this id to come from a link on a
page.
However when I am chaining Actions and need to pass values I usually set
values like that in the request scope using
request.setAttribute(SOME_CONSTANT, idObject);
then just forward to the new action
Hope this helps,
Joshua

RE: What is the best way to pass a parameter to a forward?
I have used this technique and it seems to be the only
way to have the name/value pair be passed as request parameters.
Don't think there's a request.setParameter() !!
But request.Attribute() would be the 'ideal' way to go.

Subject: What is the best way to pass a parameter to a forward?
I'm trying to solve a problem, but I'm not sure my solution is the best
way. Basically, I want to set a parameter on a forward within the
action's execute.
I'm in my action's execute method. I've just successfully performed
some work, and I now want to forward/redirect to the next page. So,
I've got some code that looks like this:
public ActionForward execute(ActionMapping.) {
// do some work
ActionForward goto = mapping.findForward( "success" );
return goto;
}
With an action mapping that looks like this:
Basically, if I left the EntrySaveAction.execute do what's doing right
now, then upon successful completion, it would redirect to
"/Container.do". However, what I want it to do is redirect to
"/Container.do?id=45", where 45 is the id of the container that I want
to go to. The value of "45" is dynamic, and is know at the time of the
EntrySaveAction.execute command.
The way I'm currently doing it is something like this:
public ActionForward execute(ActionMapping.) {
// do some work
ActionForward goto = mapping.findForward( "success" );
String path = goto.getPath();
path += "?id=" + container.getId();
goto.setPath( path );
return goto;
}
Is this the correct way to do this? Is there a better way?
Thanks in advance

Re: Extending Request Processor to append request parameter
If it does not prevent the browser from going to its cache, which is
different than preventing caching, I guess, the browser would be badly
malfunctioning, since it would be going to the cache to get a request which
is not there. Isn't this right?

Re: Extending Request Processor to append request parameter
Geeta
You don't need to subclass ActionServlet - you can set the RequestProcessor
class in the element in the struts-config.xml
Full details for the configuring the controller are in the user guide:

This is done in your struts-config.xml file: so that each module (in a multi-module app) can have its own custom RequestProcessor if need be. See the documentation in the DTD file itself (lib/struts-config_1_1.dtd) for documentation on all the things you can configure here.

Re: Extending Request Processor to append request parameter
Brad:
I looked at the API and noticed the RequestProcessor is a 1.1 feature.. Your
solution seems nice and clear! I only have one question for you though: How
do you "connect" the subclass of RequestProcessor that you wrote with the
struts ActionServlet..? Do you have to subclass the ACtionServlet too and
then join the dots there? How do you do that? There is a " processor" method
in ActionServlet which returns the processor..but I don't see a setProcessor
method..?
thanks for posting your solution: I learnt something new today..:)

Re: Extending Request Processor to append request parameter
Well, I searched through the archives with no luck on
'ParameterActionForward' or similar. I ended up trying to ovveride the
ActionForward class but couldn't get it to work well. Then I noticed in
the RequestProcessor there is a doForward() that can be ovveridden. I
wrote the following and it seems to work.
Is there a better way/place to do this than the RequestProcessor? This
seems like a prettly locical/central place to do this.
protected void doForward(
String path,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
super.doForward(addUniqueParameterToURL(path), request, response);
}
private String addUniqueParameterToURL(String url) {
if(url == null) {
return url;
}
String newURL = url
+ ((url.indexOf("?") == -1) ? "?" : "&")
+ "uid"
+ "="
+ Long.toString(System.currentTimeMillis());
return newURL;
}

Re: Extending Request Processor to append request parameter
Brad:
Here's one very simple way of achieving your objective, but I am quite
certain other people will have better ones, but since this is kind of a
cute problem, I want to offer this as well..:)
First write a simple "util" method (I always have a Util class in my apps
where I gather stuff which seems to belong nowhere else..). Anyways, write
a method with signature as follows:
private static String makeUnique(String)
which essentially takes a String (which will be a path) and will append a
"?random=aRandomNumber" (or "&random=aRandomNumber") to the end of the
input string and returns it.
In Util, also write a public method as follows:
public static ActionForward makeUnique(ActionForward actionForward) {
return new ActionForward(makeUnique(actionForward.getPath()));
}
In your Action classes, where you usually have something like:
return mapping.findForward("success")
you instead could have:
return (Util.makeUnique("success"));
I think this is an ok solution and will work.. But like I said, I think the
gurus in this list will have better ideas (perhaps more in keeping with OO
principles) ..:)
Regards,
Geeta

Extending Request Processor to append request parameter

[ot]Re: JavaScript Parameter
IE on PC (when i have to test) seems to also like complaining about
javascript where it says it doesn't find object but then the script
proceed to work anyway. And I thought id'ed document objects were
loaded into an array when the page loads to.
I seem to recall that you can install a script debugger on windoze but
i never really played with it long enough to see if it was useful or
not.
I haven't played with mozilla js debugger I'll have to give it a go.
But the only one available when i used to do a lot of dhtml development
was in the old ns4 vs ie4 days and the two doms were too far apart for
them to be useful.

RE: JavaScript Parameter
Hi,
The solution that Randy suggested works perfectly. Another possible
solution is to use the scriptlet as a declaration. ie
<%! String val=obj.getValue("Key"); %>
Then val can be used within the javascript function directly without
have to pass it as a parameter. Ie
Function jsFunction()
{
alert(<%= val%>);
}
Thanks n Regards.

You are confusing your forward called "display" and your action "/display" Clicking on the link in your jsp goes to your action - not your forward.

You have to subclass ActionMapping and declare it in your struts-config file. So when you use set-property, Struts can set those values using reflection. My guess as to why its not working is that it silently fails to set those properties because they don't exist in the default ActionMapping class. robert > -Original Message- > From: Anand Patil [mailto:[EMAIL PROTECTED] > Sent: Wednesday, February 04, 2004 4:06 PM > To: [EMAIL PROTECTED] > Subject: Using Parameter in Action via the struts-config.xml > > > Hi All, > The struts configuration DTD supports having a "parameter" attribute > to a "action".

Using Parameter in Action via the struts-config.xml
Hi All, The struts configuration DTD supports having a "parameter" attribute to a "action". But how can I get the value specified in the "parameter" attribute in my action class. Also using "set-property" inside a "action" tag does not work? Anyone have any idea about this? Regards Anand Patil

This has been raised before. See http://sourceforge.net/tracker/index.php?func=detail&aid=813006&group_id=730 68&atid=536613 I've patched the taglib to support an additional tableId attribute which can be dynamic.

[DisplayTag] Use of ID= Parameter
All, I'm in the process of implementing the new taglib, and am really excited about the ability to have multiple, independent, tables on the same page. In order to make this work, though, the ID= parameter for each table has to be different. This is where I'm running into problems. I've got my inside of a so I can generate 1-n tables - this works fine. However, when I try to vary the ID= parameter, I get ClassCastExceptions in org.displaytag.tags.TableTagExtraInfo on the following line: Object tagId = data.getAttributeString(TagAttributeInfo.ID); I've tried to define a page-scope variable and include it in a small chunk of scriptlet code, but I just can't seem to get around this. Does anyone have any ideas? Thanks!

Bean As A Parameter In A Method - Compilation Error
I followed the MVC design. I give the data access
activity (insertThread) to the ThreadHandler class.
And a bean is passed as a parameter of the
insertThread method. However, I got compilation error
saying that
insertThread(java.lang.String, java.lang.String, ... ,
java.sql.Timastamp, int, ... ) cannto be applied to
the ThreadBean.
and the error complains the statement in my action
class:
threadID = thandler.insertThread( threadBean );
This is what I did in the action class:
ThreadHandler thandler = new ThreadHandler();
ThreadBean threadBean = new ThreadBean();
BeanUtils.copyProperties( threadBean, postForm );
if (parentPostID == 0 ) // new topic
{

Redirect w. generic parameter using action forward
Hi,
Is it possible to add a parameter to the redirect when redirecting
via an action forward?
Eg.
In my.struts.Action I wish to set the parameter file=foo.txt parameter
in the redirect request, ie. effectively, I want the following to
happen:
response.sendRedirect("/streamingservlet/?file="+fileName);
Can (should) this be done with actionMapping.findForward("success");
or do I need to forward to a JSP which in turn reads the fileName as
a request attribute and does the forward?
Thanks in advance,

Action parameter field
I have an tag that is passing paramId, paramName and paramProperty to a LookupDispatchAction action. How can I set the parameter so the LookupDispatchAction functions properly? I know I can do it with javascript, but I don't like hardcoding the parameter in the jsp. I also know that the html:link tag can take a map, but I don't know how to build that in my jsp. I was thinking of having the link call a forward action and that action could specify a parameter in addition to the one that I set, but I'm not sure if this can be done, and I can't find any reference as to the syntax of the parameter attribute of an action in the struts-config.xml file. Is it something like: parameter="my.forward.location;myAction=processrequest" ? Thanks, /greg -- Gregory F.

If you are using then the hidden parameter you are passing

How can I construct STRUTS select options tag according to a parameter ?
Hi there.
How can I construct STRUTS select options tag according to a parameter ?
I got a jsp named "example_1.jsp".
One accesses the page with a parameter like example_1.jsp?id=2 .
Now what I wanna do is that the example_1.jsp get the value of id
parameter and construct select options tag dynamically.
Like below...
String id = request.getParameter("id");
USBean us = (USBean)request.getServletContext().getAttribute("USBean");
StateBean state = us.getState(id);
ArrayList cities = state.getCities();
All Beans above are set in the application scope when tomcat starts.
I dont' know how to make us.getState(id) with STRUTS select options tag,
since USBean's getState( ) method requires a id parameter.
What I'm doing now is
Using 1 more page ( actionExample.do ) right before
the example_1.jsp.
One accesses the actionExample.do with the id parameter like
actionExample.do?id=2 and forward to example_1.jsp
In the actionExample.do, get a value of the id parameter and
StateBean accroding to the value.
Set the StateBean in session scope like below.
String id = request.getParameter("id");
USBean us = (USBean)request.getServletContext().getAttribute("USBean");
StateBean state = us.getState(id);
request.getSession(true).setAttribute("state",state);
then in example_1.jsp
I don't wanna do this anymore...since eveytime users accesses the
actionExample.do , state bean is set in the session scope...
Isn't this too much work ???
Thanks in advance.

There is a note in the request.getParameter() JavaDocs that states: "If the parameter data was sent in the request body, such as occurs with an HTTP POST request, then reading the body directly via getInputStream() or getReader() can interfere with the execution of this method." You have probably used some package like FileUpload to handle the file. This package would be using the getInputStream() to extract the contents of the uploaded file (this is why you cannot access the parameters normally). This package should also provide some method of accessing any formfields or parameters that were passed. FileUpload package: http://jakarta.apache.org/commons/fileupload (I haven't used this myself) It looks like you could use this in your action to get a list of FileItems (some will be uploaded files which you can save to disk, the others would be form fields). When you find a form field, you could try adding it to the request using request.setAttribute(), which should allow you to access it using . -- Jason Lea - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I am not sure it is recommended practice to mix Map and single params in the same html:link tag, but, if all you need is to add a print=true to the end of one of your standard links, this should do the trick: Printer page Assuming you have some bean named "myBean" defined, and the value of that bean is "true", this will add both your Map of parameters and print=true to the link's query string. -Greg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Parameter with message resources
Hello,
I'm wondering on how to parameter a message, when there is a "{number}" in
the .properties.
This is an example :
In the ApplicationResources.properties, there is a little sentence
"my.text=The {0} t-shirt(s) cost ${1}".
In the JSP, how could I change "{0}" and "{1}" for their real values?
I've seen it's possible to put but I need to put
bean values, to obtain the sentence :
"The 4 t-shirts cost $20."
Thanks for your help.
Links/examples/explainations are welcomed.

or add a form bean to your action, in struts-config.xml, (static form bean or

((MyForm)form).getUserId(); // static MyForm
or
((DynaActionForm)form.get("userId");

[OT] Approaches to URL Parameter masking in Struts
After reading a somewhat interesting post by Russell Beattie in which he mentions the desire to separate the URL that a user sees from the actual logic and data that it represents, it got me thinking about the approaches that one can take in Struts to achieve something similar. I don't think the way he refers to this practice is correct. I'm more used to referring to it as URL parameter rewrite or masking. For those that don't know what I am talking about, here's an example. Say you have an URL like so: http://www.mysite.com/do/SomeAction?param1=value1¶m2=value2 After doing some magic it looks like this to the user: http://www.mysite.com/do/SomeAction/param1/value1/param2/value2 It's somewhat easy to do this if you use Apache in front of your container. Using a module, you can mask and unmask the URL before and after it reaches your container. It's somewhat common practice in PHP and Perl based sites that I've seen. That's where I first learned the trick. Why do this? Well the most common reason is to provide search engine friendly URLs. The other more interesting reason is to hide away your specific technology implementation from the URL. For example, the URL could look something like this: http://www.mysite.com/html/SomeAction/param1/value1 or even http://www.mysite.com/SomeAction/html/param1/value1 It also has the advantage of making the URLs somewhat easier to remember, if you don't have a lot of parameters that is. Cocoon seems to do this as Russell mentions in his blog. The specific abstraction between the URL and the underlying action mapping is already accomplished by using Struts. Anyway to finally get to the point, what approaches (if any) have you taken to do this in a Struts/J2EE specific way? Could a Servlet Filter be used? Throwing Apache in front of your container is not the best solution as you could be using IIS (gasp) or just serving the site from your container directly. Russell describes his approach in his Blog (http://www.russellbeattie.com/notebook/1003728.html careful it's friken long) but it doesn't seem very clean to me.

Pb with UTF-8 parameter encoding for
Hi, my links generating with with a parameter map don't work when the value of one of the attributes contains non ascii characters like "Türkei". The generated link looks like: /search.do?freetext=T%C3%BCrkei with the "ü" encoded in UTF-8 (performed in org.apache.struts.util.RequestUtils.encodeURL(String)) The problem is that this comes to my ActionForm as "Türkei". Does this mean that it gets decoded as ISO-8859-1? If I patch org.apache.struts.util.RequestUtils.encodeURL(String) to encode using ISO-8859-1 instead of "UTF-8" everything works well, but the javadoc for URLEncoder.encode() explains that UTF-8 should be used. Has someone already faced this problem? Is there a better solution to fix the problem instead of patching the struts class?

The only thing you'd have to watch would be if the client didn't
support javascript then you'd lose lookup, this would make a case for
having action as a form bean property and have some relevantly named
form elements in noscript tags. If lookup isn't mission critical then i
guess you could let this slide.
