the network is working perfectly fineThe network is timing out your connect attempts so there is something wrong somewhere.
catch will give the error msg or the entire try block. but will it give for the exact line?Suppose you try it yourself and find out?
by the way i m catching the exception i m just not printing it.Yes I am aware of that, thanks, I can read, and that's exactly what I commented on, and by the way Java forces you to catch the exception, so there's no virtue in that. On the contrary. Catchingand ignoring the exception is why its taken five days to debug this simple problem. Never do that.

Urgent - Uploading a file from HTML

How to dynamically set the value of a file (full path of the file with filename) to the tag input type=file?
In the usual scenario the user will select the file from the "Browse" button. Is this possible to set the value without choosing from "Browse" button?

Urgent? You were in so much of a hurry, you didn't notice you posted a question about HTML in a Java programming forum.

How to upload file from client to server

Can someone please help.
User needs to browse file on his desktop and upload file using browse button. This file should then be uploaded to the server. I am using javascript in the front end and servlet in the back.
Any help will be highly appreciated.
Thanks,

Jakarta Commons FileUpload is the standard way of doing the file uploading these days. You can find source, binaries and documentation at the Jakarta Site http://jakarta.apache.org/ . The Commons has a number of subprojects, so start with the Commons libraries, then find FileUpload.

You can use cos.jar provided by O'Reilly from http://www.servlets.com/cos/. Take a look at com.oreilly.servlet.multipart.* classes.
Package is provided with source, classes, documentation and, of course, ready-to-use jar file.
It is really usefull and - ready!

Upload tab-delimited file from the application server to an internal table

Hello SAPients.
I'm using OPEN DATASET..., READ DATASET..., CLOSE DATASET to upload a file from the application server (SunOS). I'm working with SAP 4.6C. I'm trying to upload a tab-delimited file to an internal table but when I try load it the fields are not correctly separated, in fact, they are all misplaced and the table shows '#' where supposedly there was a tab.
I tried to SPLIT the line using as separator a variable with reference to CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB but for some reason that class doesn't exist in my system.
Do you know what I'm doing wrong? or Do you know a better method to upload a tab-delimited file into an internal table?
Thank you in advance for your help.

Uploading large files from applet to servlet throws out of memory error

I have a java applet that needs to upload files from a client machine
to a web server using a servlet. the problem i am having is that in
the current scheme, files larger than 17-20MB throw an out of memory
error. is there any way we can get around this problem? i will post
the client and server side code for reference.
Client Side Code:
import java.io.*;
import java.net.*;
// this class is a client that enables transfer of files from client
// to server. This client connects to a servlet running on the server
// and transmits the file.
public class fileTransferClient

private static final String FILELASTMOD_HEADER = "fileLastMod";
// this method transfers the prescribed file to the server.
// if the destination directory is "", it transfers the file to
"d:\\".
//11-21-02 Changes : This method now has a new parameter that
references the item
//that is being transferred in the import list.
public static String transferFile(String srcFileName, String
destFileName,
String destDir, int itemID)
if (destDir.equals(""))
destDir = "E:\\FTP\\incoming\\";
// get the fully qualified filename and the mere filename.
String fqfn = srcFileName;
String fname =
fqfn.substring(fqfn.lastIndexOf(File.separator)+1);
try
//importTable importer = jbInit.getImportTable();
// create the file to be uploaded and a connection to
servlet.
File fileToUpload = new File(fqfn);
long fileSize = fileToUpload.length();
// get last mod of this file.
// The last mod is sent to the servlet as a header.
long lastMod = fileToUpload.lastModified();

OK - the problem you describe is definitely what's giving you grief.
The workaround is to use a socket connection and send your own request headers, with the content length filled in. You may have to multi-part mime encode the stream on its way out as well (I'm not about that...).
You can use the following:
http://porsche.cis.udel.edu:8080/cis479/lectures/slides-04/slide-02.html
on your server to get a feel for the format that the request headers need to take.

I get the out of Memory Error on the client side. I
was told that this might be a bug in the URLConnection
class implementation that basically it wont know the
content length until all the data has been written to
the output stream, so it uses an in memory buffer to
store the data which basically causes memory issues..
do you think there might be a workaround of any kind..
or maybe a way that the buffer might be flushed after
a certain size of file has been uploaded.. ?? do you
have any ideas?

How to deploy Forms, Reports and Menu from Client to Server machine

Dear Experts,
I have one requirement to deploy the Forms, Reports and Menu from client machine to server machine.
Deployment involves the following steps :
1. Firstly we have to search the selected file in a folder where the .fmx is present ( in Server machine) and take the back up of the the existing file in the server (Source and destination paths will be available).
Ex. If the existing FMB name is TEST.fmx then the backup file should be TEST_sysdate.fmx.
2. Secondly we have to transfer the file from the client folder (or from another folder of the same server) to the server folder where the back up exists.
Please help me to search/rename/copy/replace the _.fmx/.rdf/.rep/.mmx_ files from client to server.
We are using
9i Database.
10g Forms and reports.
SQL Developer tool.
OS is Windows (Client and Server).
Help me out to attach a file of front end screen which we are planning to develop. It will give a clear picture on this requirement.
Thanks :)

Welcome to the forum. Please take a while to go through the FAQ to be found to the top right of the page.
Your issue is more to do with batch files rather than Forms. The only relation with Forms, as I see it, is that you will be using HOST/CLIENT_HOST to start a batch file with the file name to be deployed as a parameter passed to it.
You need to rewrite either a CMD batch file or a Powershell script to achieve what have set out to do.
For CMD batch files look up http://www.robvanderwoude.com/battech.php , or any of the other excellent resources available on the internet.
