Hello Srinivas, java.sun.com seems to be down or overloaded, but I found this link in Google about signed applets:

Hi, Greetings. I am running into problems, as you have mentioned, i was trying to work with an Applet. Couldn't set security permissions and even if I set the permissions there could be problems with setting the user credentials. I do not know how I can make the applet access the files at client side. So, pl let me know how can I create a multipart request using HttpClient api or --how can I read the files from the file system once I get the drive and directory names from the client by using javascript, I searched the internet but couldn't find any samples to generate html form using javascript and that must create file items dynamically by reading the files from the file system. I thought of all the options that I could, but not getting a solution, which is very urgent. Pl. suggest me a solution. thanks for the help, Srinivas.

Remember you will have to sign the applet in order to access the client file system. But you could run into problems accessing the user credentials in the applet. You could also try to write JavaScript code which generates an HTML form, including one file element for every file in the directory. In that case, the browser would take care of building the HTTP request and adding user credentials. The problem once more is to access the file system from the script code. Using a combination of both could work out. It is possible to call JavaScript from an applet and vice versa. So you could write (and sign!) an applet that creates a directory listing, then use that listing in JavaScript to create a form which is then posted by the browser to the server. Other ideas? cheers, Roland Srinivas Velidanda 06.10.2004 13:43 Please respond to "Commons HttpClient Project" To [EMAIL PROTECTED] cc Subject Re: HttpClient query... Hi, Thanks for your help. I found the samples specified by you very much useful. I got it working with my JSP by sending user credential parameters which were required at my server. Now the problem is making the same with an applet as it is not working from remote client accessing the JSP. The flow is like this. I have a screen where I enter drive name, and directory to be uploaded and in the next JSP I get the files of specified folder and create multipart request and send to the server along with User credentials. Everything is working fine on the system which both client and server are running. But If I try the same from remote client then It is looking for files in the folder specified by client in server which is generating null pointer exception. Now I need to make the functionality of creating the multipart request at client side, I am planning to do it in the applet. Is it the right way to go for an applet, or can you suggest me some other solution.. thanks, Srinivas. Roland Weber wrote: Hello Srinivas, you are using HttpClient from within a JSP to connect to the server that is running the JSP? Or to a different server? If you want to set request parameters, you don't do that before creating the multipart request. You create the multipart request, then add the parameters using MP.addParameter(..) or MP.addPart(...). Just make sure to add all required parameters before you *execute* the method. See also the web site at http://jakarta.apache.org/commons/httpclient/methods/multipartpost.html The sample code for multipart file upload is for the 2.0 API, but it should be helpful anyway. Go straight to the "actionPerformed" method: http://cvs.apache.org/viewcvs.cgi/jakarta-commons/httpclient/src/examples/?only_with_tag=HTTPCLIENT_2_0_BRANCH cheers, Roland Srinivas Velidanda 05.10.2004 14:00 Please respond to "Commons HttpClient Project" To Commons HttpClient Project cc Subject Re: HttpClient query... Hi Roland, thanks for the reply. I am new to this API and pl let me know how can I do the following. 1. can I set the same parameters coming from the session before creating Multipart request to the Multipart request, if yes, how can I set and how can these parameters can be referred at the server side. 2.I am getting the session parameters in the JSP where I am creating Multipart request, but once I post the Multipart request to the server the session is getting killed. We are not working with cookies. Is there a solution without using cookies or I must go for cookies.. thanks, Srinivas Roland Weber wrote: Hello Srinivas, if the session is handled by a session cookie, just make sure you use the same HttpState object for all requests. That should happen automagically if you do nothing special and re-use one HttpClient for all requests. If the server uses URL rewriting because it believes that the client can't handle cookies, you have a problem. You will have to parse server responses in order to extract URLs with the session information encoded in them. Or convince the server to send cookies. hope that helps, Roland Srinivas Velidanda 05.10.2004 13:32 Please respond to "Commons HttpClient Project" To [EMAIL PROTECTED] cc Subject HttpClient query... Hi, I am using HttpClient (commons-httpclient-3.0-alpha2) api for file upload. How to handle a session if I am creating a MultipartPost request in a JSP and posting the request using client.executeMethod(mPost) to a servlet URL. Once I send the request the session is getting killed and could not pass on the request to a specific handler in sequence.. Pl. let me know how to handle the session, if possible send me some sample code for that. thanks in advance.. Srinivas. --------------------------------- Do you Yahoo!? New and Improved Yahoo!
