Download files...Very Urgent!!!!!!!

Hi All,
I want to download same HTML files from the web using Java.
u = new URL("http://www.insproplus.com/press.htm");
URLConnection uc = u.openConnection();
BufferedReader in = new java.io.BufferedReader(new InputStreamReader(u.openStream()));
String rec = null;
while ((rec = in.readLine()) != null)
html += rec;
in.close();
This one is throwing the IOInterruptExpection: timeout exccetion no further information.
My program is Application. not Applet.
Can you give some suggestion and ideas how to download files(HTML pages) from the net?
Best Regards,
Muthu

Hi,
I found the solution for the exception.
we must have set the proxy host on our networkt.
UNIX
java -Dhttp.proxyHost=proxyhost
[-Dhttp.proxyPort=portNumber] runableClassName
DOS shell (Windows 95/NT)
java -Dhttp.proxyHost=proxyhost
[-Dhttp.proxyPort=portNumber] runableClassName

  • Running a batch file - VERY URGENT .. help

    Hi people
    I am attempting to run a batch file from with a JSP page.
    the code i am using is:
    Runtime runtime = Runtime.getRuntime();
    Process process = runtime.exec("cmd.exe /c d:\\uploadfiles.bat");
    This jsp file is located on the c: of a webserver.
    the uploadfiles.bat is located on the d: of the webserver and the code is:
    copy d:\videos\008214?.rm d:\blah
    copy d:\images\008214.* d:\blah
    copy d:\xml\008214.* d:\blah
    cd \blah
    pkzip -es -m 008214.zip *.*
    copy 008214.zip d:\upload\008214.zip
    del 008214.zip
    If I run this batch file from a command line, it works fine, though when I try and call it through my JSP page, it doesnt do anything .. a command window just pops up for a while, and then closes.
    How can I fix this ... I need this quite quickly
    Thanks people

    1) It is O.K. that you see nothing in that console. Its output is captured by Java and is not displayed on the screen.
    In general, that console should not be visible, but actually it behaves differently according to JDK and OS versions (treat that as a feature).
    2). Look at this article:
    http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
    It it does not answer your problem, try to search the forums:
    http://search.java.sun.com/search/java/index.jsp?qp=%2Bforum%3A31&nh=10&qt=%2B%22exec%22+-%22Replies%3A+0%22&col=javaforums
    Questions about Runtime.exec() has been asked hundreds of times.
    3) runtime.exec() can execute BAT files. It is not necessary to specify that "cmd /C".

  • About XLIFF translation File Very urgent

    Dear all ,
    I am trying to translate the error messages in the APEX using the file XLIFF
    I did the following :
    1-Map your primary language application to a translated application
    2-Seed and export the translation text of your application into a translation file.
    3-Translate text identified in translation file.
    4-Apply your translation file and publish.
    but it didnt display the translation for the messages,so I opened the XLIFF file and i saw all the messages in the application inside the file but it is not translated,
    so i changed it manually from the file itself then i exported the translation file into the application and i publish it ..
    but it didnt make any effect to the application i checked the file itself it is changed there but it doesnt make effect on the application ...
    actually i need to change the file manually from the OS not from the application coz it will not show all the component of the file ..
    Thanks in advance

    Hi,
    SAP BC and SAP NetWeaver are based on different technologies: SAP BC is based
    on webMethods’ proprietary Integration Server, whereas SAP NetWeaver is based
    on open standards, such as BPEL4WS (business process execution language for
    web services). Therefore, only parts of an SAP BC implementation, such as XSLT
    mappings, can be migrated to a solution based on SAP NetWeaver. Any custom
    programming based on SAP BC, such as SAP BC flow language, is unlikely to be
    reusable in the SAP NetWeaver context.
    The basic steps in the back-end systems are:
    • Defining the logical systems
    • Maintaining the ALE distribution model
    • Maintaining partner profiles and EDI ports
    • Maintaining RFC destinations
    The basic steps in the SAP XI system are:
    • Maintaining the System Landscape Directory
    • Configuring the IDoc adapter
    • Maintaining the receiver determinations, interface determinations, and
    interface agreements
    • Maintaining the communication channels
    The type of scenario to migrate typically has an impact on the communication channels only.
    >>>how to migrate from BC to XI in this kind of scenario. Will i use RFC and File adapters in my XI to configure the same?
    Yes , for RFC communication you need to use the RFC adapter as you know in BC you need to create the connections and you can also test you RFC and BAPI and also you can check what XML string is coming in return. So i guess that XML you can use in XI also. Also you can use file adapter.
    Hope this will help you.

  • Upload file in clustered environment- Very Urgent

    Hi,
    My requirement is to upload a file onto the WebServer and also list out the file names on the front end and provide a funcionality to delete them from the server.
    Environment Details:
    -Product: WebSphere Portal
    -Type - Clustered Enviroment with 2 nodes
    -Framework: JSF
    The problem I am facing here is:
    1) I login to the application using a common URL: Say abc.com/wps/portal
    2) I dont know which node I am logged into, it can be either Primary(X1) or Secondary(X2).
    3) I click on the browse button and select a file and click on the Upload button. The file is uploaded successfully on say primary node X1.
    4) I can at that time read the name of the file and display it on screen and also select and delete it. But if I log off and login again and say I am now redirected to secondary node, I am not able to read the name of the file I uploaded as it is stored on the primary node.
    Can some body provide me a solutions to this.
    What I can think of is , While uploading the file, I will check if I am on the primary node or secondary node and Upload the file only on one node rather than uploading them on both. Say uploading only on primary node X1, Now if I am logged into primary I can just mention the directory name and upload it.
    But I f am on the secondary node I need to upload the file on the primary node using URL connection.
    Can some body tell me the feasibility of this approach ?? Also how do I upload a file on a remote machine(Logged into the secondary but putting the file onto the primary node.) ???
    Please help me this very very urgent.
    Thanks.

    Hi!
    I would simply use a network share which is accessible from both nodes as storage. This way you don't have to care to which server the file is uploaded too, because both share the same filesystem.
    If you are on windows, simply share a folder and access it from both nodes. In Linux I'd suggest using samba & mount, on solaris use share & mount.
    Another approach would be to use a database as storage.

  • How to send Zip files as attachments !! Very urgent, Please help!

    I am sending PDF files as attachments using java mail (it works fine). But now my requirement is to zip the PDFs and send them as attachments instead of actual PDF's. But i don't know how to achieve that. does java mail API support zip attachment facilities? I have looked in activation API also, but i couldn't find anything helpful. even i searched the forums, but no clue. Please, anybody help me about this, it's very urgent.

  • Downloading files using HttpConnection is very slow

    Hi
    I've written a program which will download files over HTTP protocol using the class HttpConnection. I am connecting to the net using Proxy with authorization. At times it takes long time to download even a 2 MB file, but it works very fast on fewer occasions. The same file If I try to download using browser such as IE or FireFox, download happens in few seconds.
    I am not sure where the problem is. Can anyone guide me on this issue?
    Regards,
    Faisal

    The HTTPUrlConnection do not seem to utilize the
    Connection Keep Alive feature of HTTP so it createa
    seperate connection for each request.Eh? The Sun implementation can utilize HTTP
    Connection Keep Alive if you tell it to, and it also
    runs a connection pool.Great! can you explain a bit how you enable it?
    Can I just do it by setting the Connection: Keep-Alive header
