Re: Connection and Tomcat server
I can say, this is purely a connection closing problem. That's the reason when you restart the tomcat it works fine till the time all the connection in the connection pool utilize and then after it hangs.

message of request scope will be displayed with other requests also
We are using following line of code saveErrors(request, errors) and saveMessages(request, messages) but even the scope of errors and messages are limited to request. It stores messages in session.

concurrency management
Hi, How do we will manage concurrency if suppose we have connection pool which is managed with struts1.1 on tomcat.

double click submit button problem
Hi,
To avoid double click problem we implemented code in our execute method as
follows
saveToken(request);
if(!isTokenValid(request){
//submit
mapping.forward(target);
}else{
resetToken(request);
}
but then the page is not working as expected whenever we double click the page
is not getting submitted at all, can anybody suggest what wrong I am doing.
For your information we are using one Action class per form so I am setting
saveToken method in execute method as per form.

Re: struts is giving error on weblogic81
Well, We solved the problem, there is a one file commonspool.jar which is missing. Once we added in war file it worked fine. But then we started getting another error as given below(ie. try block too large), which is because of big size of jsp page. But which works absolutely fine on tomcat. We searched in net and found that it can be solved by breaking jsp and pieces and then using include tag, but then again for one page we need to develop two form beans as we are using to jsps.

strange tomcat problem with struts1.1
Hi All,
We are facing one strange problem, our server hangs after every 2-3 days. The
reason behind it, is it tomcat creates unwanted java processes.
>From my side I haven't implemented anything special except adding
"synchronized (this) {" line in execute method so that I can avoid
concurrent request.
Will it be the reason?

Hi All,
I am following query to insert value in databse now suppose value of
"webpurchased","targetadvt" and 'trial" is null then how can I can insert
same null value in database.
Because my parameter is like String webpurchased=null --In this case value of
webpurchase will be replaced by string 'null' while insering, which is
meaning less. I want to insert real null.
MY query:
stmt.executeQuery("INSERT INTO advt_spns_soln VALUES "+
"(advt_spns_soln_id.nextval,'"+firstName+"','"+lastName+"','"+title+
"','"+
company+"','"+companyAddress+"','"+city+"','"+stateId+"',"+postalcode+",'"+
country+"','"+email+"',"+phone+",'"+url+"','"+campaign+"','"+webpurchased+"','"+
targetAdvt+"','"+trial+"','"+budget+"','"+marketobjective+"','"+emailupdate+"')");

HttpSessionListener Interface
If there are multiple sessions getting destroyed? Which session will get first destroyed? or sessiondestroyed method will override old session? -Jignesh - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: session form "reset"
Go through with SessionBindingListener and SessionAttributeListener. And implement the appropriate one. -Jignesh On Thursday 22 April 2004 20:29, Matt Bathje wrote: > Hey all - I'm having a small problem and was wondering if anybody could > help. > > I have a page with a form, that when I submit, comes right back to the same > page with the updated information.

HttpSessinoListener Confusion
If we will use HttpSessionListener, will tomcat implement seperate listener for all the Sessions or it will be common for all the sessions? -Jignesh - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Timer implementation with servlet
Hi All,
I am trying to implement timer with servlet but it works only at the time of
loading only while I schedule it to work after every 1 minute.
What is the reason for not working later on?
My servlet code is as follows:
public class TimerServlet extends GenericServlet implements SingleThreadModel
{
public void init(ServletConfig config) throws ServletException {
Timer timer = new Timer();
System.out.println("timer started");
timer.schedule(new SessionTrack(),1000);
}
public void service(ServletRequest arg0, ServletResponse arg1) throws
ServletException, IOException {
}
public String getServletInfo() {
return null;
}
}
And code for TimerTask is as follows:
public class SessionTrack extends TimerTask {
public void run(){
System.out.println("sending email");
Mailer mailer = new Mailer();
mailer.sendMail("profile","[EMAIL PROTECTED]");
}
}
