RE: Slow file upload?
Don't know if its really bug because it does actually work just fine; it just chews up allot of CPU when doing network I/O. I'm not sure if this only happens on Windows boxes or if it happens on other platforms as well. The thing about Netscape/Mozilla is that it runs on allot of different platforms. And many of the different platforms have a slightly different take on how you do asynchronous non-blocking network I/O. So they probably have created some library to abstract out these differences. Now maybe its a bug in how they implemented asynchronous non blocking I/O on windows or maybe they just decided it would be easier to poll rather then handling the many different ways different Os's can provide asynchronous notification that there is more data available or that its OK to send more data. -Original Message- From: Bjørn T Johansen [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 16, 2003 11:04 AM To: Struts Users Mailing List Subject: RE: Slow file upload?

RE: Slow file upload?
If you are running on a Windows box, I would try using IE instead of Mozilla for your timing tests. On windows, Netscape and thus probably Mozilla, seems to spin in a hard loop poling for new data while its trying to receive data over the network. This results in 100% CPU utilization and really slows things down. It might just be that it also spins in a hard loop when its waiting for the transmit buffer to empty enough so it can continue to send more data. -Original Message- From: Daniel Washusen [mailto:[EMAIL PROTECTED] Sent: Monday, September 15, 2003 11:54 PM To: Struts Users Mailing List Subject: RE: Slow file upload? > Yes, I am using Struts 1.1 and the default upload in commons-fileupload. > The hw I am running on is a 2.4GHz PC with 1GB memory, with at least > half of it free..

RE: Avoid Validate After Submit
Here's how I do it in Struts 1.1. I'm not sure how 1.1 is different from
1.01 in the validation area so your mileage may very.
First I have a base class for all my ActionForm's called ExtendedActionBase.
Among other things, this class defines some standard button name for "next",
"back", "cancel", and "OK" verbs. The class will only perform validation if
a "next" or "OK" button was used to submit the form. There's also some
extra junk in the class that has to do with accepting either simple buttons.
The only other thing you need to do is on "back" and "cancel" buttons make
sure they are buttons. This insures that the JavaScript
validator will not validate the form.
I'll include ExtendedActionBase.java below.
Hope this helps,
Kurt

RE: Populating form from request parameters in JSP
Hi, I just started using struts. And like you, I thought creating all the extra Action mappings and Action objects would add extra complexity. So I created an enhancement request asking that a new method be added to the ActionForm object which would be called when the ActionForm is created. This method would be passed the HttpRequest which caused the ActionForm to be created so that the ActionForm could use the HttpRequest object to pre-populate itself without the need for a separate action. But someone in struts-dev mentioned that ActionForm.Reset() is called after an ActionForm is created in addition to being called just before HTML form values are populated to the ActionForm's properties. This was great because it provided the functionality I was looking for. So basically what happens is that when an element is referenced in the JSP, the ActionForm which matches the 's "action" property gets created if it doesn't already exist. Since you know the first call to reset() corresponds with the creation of the ActionForm object, you can do all your initialization. Then when the JSP continues on to render other fields in your form, they will be populated with good data. I tried it out and it worked great. I didn't have to make any Action objects just for the purpose of initializing ActionForm objects. I just let the ActionForm objects take care of it themselves on the first call to reset(). I also configured struts to keep the ActionForm on the session scope so that the ActionForm wouldn't have to go through an extra initialization when the user actually clicked the submit button on the form rendered by the JSP. The only thing that worries me is that the behavior of calling ActionForm.reset() upon ActionForm creation is not documented so I'm a little worried that future versions of Struts may change this behavior. But taking advantage of the current behavior makes prepopulating forms allot easier so I'll take my chances. What can I say, I'm lazy :) Kurt -Original Message- From: Ajay Patil [mailto:[EMAIL PROTECTED] Sent: Friday, July 11, 2003 6:21 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Populating form from request parameters in JSP Thanks Nagi, Atleast I know that I am not doing something wierd. Anyway, why does the JSP page care about the origin of the forward. Why cant it simply autopopulate the form from request parameters ? Defining an extra action class just to do the forward seems to unnecessarily increase complexity. What do you think ? Ajay hi, your two jsp pages have different action forms associated with them. so u cant expect the second jsp page to autopupulate the previous request parameters. u have to go thro' the struts thing(action class) which will then autopopulate ur new action form and then the jsp page associated will show the values.. if both ur jsp pages share a single action form(which is in session) then the second jsp page will automatically show the values hope its clear now -- nagi ---Original Message--- From: Struts Users Mailing List Date: Friday, July 11, 2003 12:33:32 PM To: [EMAIL PROTECTED] Subject: Populating form from request parameters in JSP Hello, I know this question has probably been asked several times. But, possibly a Struts developer can explain because I am confused. Generally, my action classes receive posted data, query the database, put the query result as request attribute and then forward to the next JSP. However, I find that form properties in the next JSP dont get auto-populated from the request parameters. So, I define a new action class (associated with the next form), and use it simply for forwarding. And then I can see the form properties auto-populated. So, why is this extra step (or extra action class) needed ? Or am doing something wrong here ?
