Subject: Multiple submits
Hi All,
I am facing a problem related to multiple sumbits.
We are developing a wizard kind of application with frames. For this we
use business object(BO), which are nothing but a replica of forms, used
in JSPs. We store this BO in session and keep on updating it with the
values present in various forms. At the end, we pass this BO to EJB
layer to process the DB operations after which we display success or
failure page depending on the success of DB operation. To do final
submit we display OK and Cancel button in all the JSPs along with Next
button. After successful DB operation we remove BO from session (to make
session light).This is where our problem starts.
If user clicks final OK and first thread completes the DB operation;
just before the success page loading user clicks Next button. Then
second thread tries to look into BO which was stored in session, for
some values. Since first thread has already removed the BO from session,
second thread throws NullPointerException. Not only this if user clicks
OK button, more than once then we land up either with same record
entered in DB more than once or again NullPointerException.
I went through various threads and almost every where people talk about
using Tokens. If I use tokens then what shall I do if token is invalid?
I can't show him a page saying that your first request is under process,
'coz at the end I have to forward the request to success page.

session var missing in .jsp
All but one of my .jsps are views and go though my template. They're all
mapped to screenname.screen. I have code (shown below) at the top my
template to check a session var to see if the user has logged on. That works
fine.
But now I have a .jsp that's just for displaying an (crystal clear report
viewer) applet. And the .jsp has call back functions used by the applet, so
I can't use the template. I put this code at the top of my rptloader.jsp,
but I get a NPE in this case.
%
try
{
if (session != null){
com.monolith.model.administration.User user =
(com.monolith.model.administration.User)session.getAttribute(
com.monolith.webapp.Constants.USER_KEY);
if (user == null)
response.sendRedirect(/WebSynapse/signon.screen?prob=no);
}
else
response.sendRedirect(/WebSynapse/signon.screen?prob=yes);
}
catch(NullPointerException npe)
{
response.sendRedirect(/WebSynapse/signon.screen?prob=npe);
}
%
I have a selectreport.screen that ends up at my ReportViewAction where I
figure out what kind of report was requested. Then to actually execute the
report I do:
if (usePDF == true)
return (new ActionForward(/report.pdf, false));
else if (useHTM == true)
return (new ActionForward(/report.htmr, false));
else
//response.sendRedirect(/rptloader.jsp?report=/reports/+reportType.trim()+
.rptdll=pdsora7.dll);
return (new
ActionForward(/rptloader.jsp?report=/reports/+reportType.trim()+.rptdll=
pdsora7.dll, true));
//return (new
ActionForward(/rptloader.screen?report=/reports/+reportType.trim()+.rptd
ll=pdsora7.dll, false));
It's the default case I'm talking about (the other's will eventually go
away). I've tried several different options for kicking off rptloader.jsp.
It seams that when I go directly to rptloader.jsp, my session var is
missing. What am I doing wrong?

Anyway, I've got the authentication/authorization piece working, and can generate custom nav bars by user based on a persistent profile stored in an Oracle database. As long as the applications that I link to are Java/JSP based, I can pass around a set of JavaBeans containing the users information without any problem. How do I get this information over to a .ASP app? Can this even be done? Short of passing around XML data structure ala web services, I can't seem to find an easy (or hard) way to do this.

[RE: Redirecting to login page when session expires
I assume you mean processActionPerform; I don't see perform() in the
ActionServlet. Here's what I ended up with and it works well:
protected ActionForward processActionPerform(Action action,
ActionMapping mapping,
ActionForm formInstance,
javax.servlet.http.HttpServletRequest request,
javax.servlet.http.HttpServletResponse response)
throws java.io.IOException,
javax.servlet.ServletException
{
HttpSession session = request.getSession();
String path = processPath(request);
User user = (User)session.getAttribute(Constants.USER_KEY);
if (user == null !path.equalsIgnoreCase(/LOGON))
{
ActionForward logonForward = findForward(logon);
return logonForward;
}
else
return
super.processActionPerform(action,mapping,formInstance,request,response);
}
Now I wan't to use the same technique at the top of my .jsp pages. In
particluar, I wan't to test for a timeout and then direct the user to the
logon page via the normal processes flow. We have a site template doing
response.redirect bypasses the logic that includes the template info. So my
question is how can I do an ActionForward from a .jsp?

What's the most elegant way of redirecting the user to the login page

Here's a simple approach:
Override the ActionServlet's perform method to check the session for
something that your login action should've put there. If it's there,
return super.perform(). If it's not, return findForward(login),
assuming you have a global forward in your struts-config called
login.
A more elegant approach might involve the use of a filter (Servlet
2.3) instead of an ActionServlet derivation, but the idea of looking
in the session for something indicating a successful login is the
same.

calling processActionForward from processesPreprocess in struts 1.0.2 timeout checking
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg15542.html
suggests calling processActionForward from unauthenticatedUser, which is
called from processesPreprocess, to handle timout checking. But in the
stable release processActionForward needs an ActionMapping parm. So I change
the example code to this:
private void unauthenticatedUser(
HttpServletResponse iResponse,
HttpServletRequest iRequest,
String iRequestedPage)
throws IOException, ServletException {
HttpSession session = iRequest.getSession();
ActionErrors errors = new ActionErrors();
// redirect to the login servlet (passing parameter)
String path = processPath(iRequest);
this.log( User is not logged on in session
+ session.getId());
/*errors.add(ActionErrors.GLOBAL_ERROR,
new ActionError(error.notloggedin));
saveErrors(iRequest, errors);*/
ActionForward logonForward = findForward(logon);
ActionForward forward = new ActionForward(logonForward.getPath(), true);
//forward.setPath(forward.getPath() + ?page= + iRequestedPage);
processForward(processMapping(path,iRequest), iRequest, iResponse);
}
This function is being called when a timout occurs, but the forward to my
logon page never happens. I just get a plain white screen. (The address bar
shows me the name of last screen I was on.)

You can prevent multiple submits in the client side using JavaScript. Below
is some code that you can see in action at
https://www.cyclewacko.com/ChangeInfo.asp?mode=newGoTo=youraccount.aspSSL=
yes
//--
/SCRIPTSCRIPT language=JavaScript type=text/JavaScript
!--
//This include file contains some JavaScript functions to prevent users
//from submitting a form twice. It sets a flag (FormSubmitted) to false
//when the page first loads. Then, when the form is submitted, this flag
//is checked. If it is true, it tells the user that they have already
//submitted the form and prevents the second submission. If it is false
//it toggles the flag true (which prevents the next submission) and
//submits the form. The flag can be reset if subsequent submissions are
//required. One example would be if the user changes information on the
//form and then re-submits. In this case, the ResetFormSubmitted function
//should be called in the onChange event of any form item that can be
//changed.
//Initialize the FormSubmitted variable
var FormSubmitted = false;
function DoubleSubmitCheck() //Call this function in the form's onSubmit
attribute
{
//Check if the form has previously been submitted
if(FormSubmitted) //It was
{
//Alert the user and cancel the submission
alert(You have already submitted this form. Please wait for it to be
+ processed...\n\nNOTE: If you pressed your browser's 'Stop'
button
+ after submitting this form, you'll have to press the
'Reload' or
+ 'Refresh' button before you can re-submit.)
return false;
}
else //It was not (this is the first time it was submitted
{
//Set the FormSubmitted flag to true and return true to process the
form
FormSubmitted = true;
return true;
}
}

Subject: Usage of Action Tokens - preventing application 'damage' by
impatient users
Hi,
I guess it is a common problem of web applications that they need to track
how many times a user clicks a submit button. Assuming, that a click on the
submit button executes an expensive stored procedure on a database server
which may take 10 to 20 seconds, lots of users get impatient and click the
submit button again and again.
I tracked this down and noticed, that every click executes the perform
method of my Action class. In fact the server executes the procedure as many
times as the user clicks the button.
In the struts framework I found in the Action class the following methods:
generateToken(), isTokenValid(), resetToken() and saveToken()
Could anybody explain how and where to use these methods best to prevent an
action from executing multiple times?
I see the following processing inside the action.perform() method:
1) getParameters from the form
2) determine whether the form needs first to be delivered or the user input
needs to be processed
if user input needs to be processed continue with 3) otherwise deliver the
form...
3) validate the parameters
4) process request
5) catch any errors and return them (if there are any)
6) deliver the results by forwarding to a view template
In my opinion the steps 3 to 5 should be treated like a transaction and any
further submits from the same session should not be processed. Could anybody
please post an exemple how to solve that problem best?
Many thanks
Thomas

[OT] Problem calling stored proc in Oracle 8.0
I'm trying to call the following stored proc:
PROCEDURE cancel_order_request
(in_orderid IN number
,in_shipid IN number
,in_facility IN varchar2
,in_source IN varchar2
,in_userid IN varchar2
,out_msg IN OUT varchar2
)
which I can call successfully when pointing to an Oracle 8i database (using
the 8i driver), but I get the following error when using the same database
running under Oracle 8.0 (using the 8.0 driver):
java.sql.SQLException: ORA-01460: unimplemented or unreasonable conversion
requested
I have the same problem with another proc. The only difference I can see
between the ones that work and these two that don't is the ones that don't
work have IN OUT parms (e.g. out_msg).
Here's the code that calls the proc:
private static String cancelOneOrder(String orderID, String sFacility,
String reason, String sLogin, String sShipID){
// int theLoad = getOrdLoad(orderID);
long shipId = Integer.parseInt(sShipID);
//String sFacility = getOrdFacility(orderID);
String outMsg = ;
String sSQL = null;
Connection cConnection = null;
CallableStatement cs = null;
System.out.println(Cancel ORDER: + orderID );
try
cConnection = dataSource.getConnection();
try
{
cs = cConnection.prepareCall({call
zorderentry.cancel_order_request(?,?,?,?,?,?)} );
//cs.setBigDecimal(1,BigDecimal.valueOf(Long.parseLong(orderID)));
//cs.setBigDecimal(2, BigDecimal.valueOf(shipId));
// cs.setInt(1,Integer.parseInt(orderID));
//cs.setInt(2,Integer.parseInt(sShipID));
cs.setLong(1,Long.parseLong(orderID));
cs.setLong(2,Long.parseLong(sShipID));
cs.setString(3,sFacility);
cs.setString(4,WEB);
cs.setString(5,sLogin);
cs.registerOutParameter(6, Types.VARCHAR);
cs.executeUpdate();
}catch(Exception e)
{System.out.println(RS);System.out.println(e);}
ResultSet rs = cs.getResultSet();
outMsg = cs.getString(6).trim();
cs.close();
}catch(Exception e) {System.out.println(e);}
System.out.println(OUTMSG: + outMsg);
return outMsg;
}

RE: Reloading a page without refreshing Remote Scripting)
I did remote scripting in the ASP world. I haven't heard of it being used in the JSP world, but I haven't been around that long. Anyway, one time remote scipting is used is for dependent list boxes. For example after the user selects a country from one drop down list, the state/prov dropdown list is then populated w/ the appropriate data. An alternative to remote scripting in this case is to use JavaScript. All the data has to be pre-loaded into arrays, but then you can dynamicly populate dropdowns on the client side. Note too that remote scripting doesn't work w/ all browsers. I think we had to take the JavaScript approach w/ Mac browers. For an example, see http://www.cyclewacko.com. -Original Message- From: Rao, Sarveswara [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 13, 2002 10:14 AM To: 'Struts Users Mailing List' Subject: Reloading a page without refreshing Remote Scripting) Hi I have to developed a Page in which user enters the Zip Code and fields like City Name, State Name have to be populated without refreshing the page.

That link was to info mostly about 8i (Build 8.1.7). I need it work w/ Build 8.0.5. I followed a link to JDBC Driver-Database Compatibility and found this info which I don't totally understand: * Different JDKs require different class files--classes in classes12.zip, classes111.zip, and classes102.zip, respectively * Note: the JDBC server-side internal driver is not available for 8.0.x and prior versions. * The JDBC drivers do not support structured objects when run against an 8.0.x database.
