Problem with url.openConnection

Hi everyone. I have created an applet that runs ok in appletviewer. The problem is that if I load it from IE an exception occurs. THis is because, at some point I want to read a file, and I do url.openConnection. The getContentLength() method of the urlconnection then returns -1 instead of the real file's size. I have to notice, that I have created .jar file for my classes and I use signatures for loading my applets in the browser.
Any ideas?
Thanx in advance,
Theodore

That made sense, so I changed my imports from:
import com.sun.net.ssl.internal.www.protocol.https.*;
import com.sun.net.ssl.internal.ssl.*;
to
import javax.net.ssl.*;
and successfully recompiled. It was hopeful at first because It crashed on some permissions. As soon as I corrected the permissions in java.policy, that damn ClassCastException was back.
Is this still the way to do it using javax.net.ssl?
System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
Security.addProvider(new sun.security.provider.Sun());
URL url = new URL(authurl);
HttpsURLConnection connection = HttpsURLConnection)url.openConnection();
Thanks for your time...

I think the real problem is that you don't check the return value from read (it's probably less than data.length indicating an incomplete read). Isn't there a readFully somewhere?

Problem with URL:s containing scandinavian characters (Office 2013 / Firefox / SP 2010)

We are encountering problems with document opening when URL contains scandinavian characters (ä,ö). This issue occurs only with Office 2013 when using Firefox. With IE it works just fine. And Office 2010 works nicely as well.
Error message: "We can't connect to 'https://intra.../Test powerpoint.pptx' Please make sure you're using the correct web address".
This issue only occurs when document or document set name contains scandinavian characters. If I rename it, document opens without any problems.
Any idea how I could fix this?

Hi Law, try changing the settings in the library to "open in client application." You should also read the following links for solutions:

Are you trying to upload from individual Domain.sites files? It looks as if the redirects aren't working, and that's due to problems with index.html files--a common issue in '08 if you are trying to publish individual sites from separate/individual Domain.sites files. Moreover, the site(s) you are looking for may not show up because they may not even be on the server anymore. Domain.sites2 files, (iWeb2.0.1) will erase previously published sites on the iDisk when published.
Your username url wants to go to a site that doesn't seem to exist anymore on the server: HerringMemorabilia.
Best thing to do at this point is to have a look at the server itself. Use the Go menu in the Finder to navigate directly to the iDisk sites files, and see what is and what is not actually on the server:
Go/iDisk/My iDisk/Web/Sites/SitesShouldBeHere/
Also, while you are there, take a look at the directory that 1.1.2 used:
Go/iDisk/My iDisk/Web/Sites/iWeb/SitesShouldBeHere/
Once you see what is there you will be in a better position to diagnose the problem, e.g., issues with index.html files.

Programming Web Item. Problem with URL creating

Hi,
I am trying to programm a own Web Item.
I derived from the class CL_RSR_WWW_ITEM_VIEW.
Everything is worken fine. I just have a problem with
the creation of links.
In the WAD there is the very nice way of using SAP BW URLs
like:
<SAP_BW_URL cmd="PROCESS_HELP_WINDOW"
help_service="ZPRINTING"
item="TABLE_1"
suppress_repetition_texts=""
P_PREVIEW_MODE=" ">
Is the a method or something similar to do the same with abap?
Greetings
Mike

I found out mayself!
You just have to use the object CL_RSR_PARAMETER.
There you can add parameters.
Then use the method get_url of the object CL_RSR_WWW_PAGE to make a URL string out of it.

Problems with URLs generated for My/BEx Portfolio in a FPN

Has andone successfully configured a FPN that uses My/BEx Porfolio?
We are facing a problem with the URLs generated when launching a BEx web query stored in either My Portfolio or BEx Portfolio after it has been saved from the BEx Web Analyzer. After saving the KM document in My/BEx Portfolio in BEx Analyzer attempts to execute the link from the Portfolio IView result in "Page not found or not avaialble". The KM document appears to be correct as it can be opened correctly from the BEx Analyzer template.
Current Setup:
Consumer Portal: EP 7 (SP17)
Producer Portal: EP 7 (SP17 patch 11)
BW System: BI 7 (SPS16, BW SP18)
SSO and Trusts are configured and working.
WebDav is configured to store BEx Portfolio entries on the Consumer
Currently RSPOR_T_PORTAL is configured with hostname of Producer, however it was initially configured with Consumer host, resulting in the same problem, though this should not matter, as the RDL IView is used regardless of the setup.
Scenario:
Existing Roles have been imported from BW System into Producer Portal, the roles are not used, only the imported IViews
IViews of the Queries have been included in Consumer Roles using RDL
IView has been added to this role to display local BEx Portfolio links
RDL IView has been added to this role to display Producer My Portfolio links
1. Launch IView of Query included in Role
2. Use Save As functionality to store KM document in My Portfolio or Bex Portfolio
3. Open the cooresponding Portfolio IView and click on the link
Here's an example URL resulting from launching the link
http://pportal.lhoist.com:50000/irj/servlet/prt/portal/prteventname/navigate/prtroot/pcd!3aportal_content!2fevery_user!2fgeneral!2fdefaultDesktop!2fframeworkPages!2fframeworkpage!2fcom.sap.portal.innerpage?BOOKMARK=D4UE3NQC7T5MUXILOGH6GV7LC&BI_TARGET_IVIEW=fpn%3AEP%2Fpcd%3Aportal_content%2FLhoist_BI%2FRoles%2FLhoist.MyReporting%2FStandardReports_2%2FSales%2FProfitability%2FSales_Quantity%2FMPXXSAP103_00000071%3AhRPQZv3B9%252BE66ckUgr9%252Fcg%253D%253D%3A1%3A&NavigationContext=fpn:EP/pcd:portal_content/Lhoist_BI/Roles/Lhoist.MyReporting/StandardReports_2/Sales/Profitability/Sales_Quantity/MPXXSAP103_00000071:hRPQZv3B9%2BE66ckUgr9%2Fcg%3D%3D:1:&windowId=WID1231315538117

Problem with URL - Applet

hi, i have a little problem running my applet. it's supposed to get a file from the WWW and display its contents as a string inside a JTextArea. the file on the web is a simple .txt containing little text, say one sentence, its irrelevant here. the file is read in inside a different class that the applet calls. however, there seems to be a problem with that - maybe it has something to do with Applet restrictions. anyway. here goes:
the applet (i removed all irrelevant applet construction objects like buttons etc) -
public class Applet1 extends JApplet {
private JTextArea sisestaJutt;
private String juttVeebist;
public void init() {
URLReader veebist = new URLReader();
try {
juttVeebist.equals( veebist.reader());
catch(Exception e) {
Container sisu = new Container();
sisestaJutt = new JTextArea(juttVeebist);
sisu = getContentPane();
sisu.setLayout( new BorderLayout() );
sisestaJutt.setBorder(brdr);
sisu.add(sisestaJutt, BorderLayout.CENTER);
the called class (& method) -
public class URLReader {
public static String reader()
throws Exception {
URL jjstreet = new URL("http://www.anydomain.com/file.txt");
BufferedReader input = new BufferedReader(
new InputStreamReader(
jjstreet.openStream()));
String inputLine = input.readLine();
input.close();
return inputLine;

thank you everyone for information, it's getting clearer to me already. sounds like signing would do the trick.
however, i first tried this thing on a localhost - thats the server-program and applet at the same place, even writing in the same dir... but the text ment to be inside the textarea is still from a URL, so i guess applet has trouble getting input from the www then...
anyway, JFrame is working very good + it has the comfortable command line feel in it =)

Problem with URL iView regarding fetch mode and SSO to non-sap webapps

Hi,
I have created an URL iView which opens an internal webapp. When the fetch mode is set to client-side the page is displayed for the user. But when I set the fetch mode to server-side, the page cannot be displayed by the user.
No proxy is needed. I tried to open the wepapp direcly on the portal server without any problem. Are there any additional points to be considered?
On the other hand I want to realize SSO to this webapp (form based authentication) with user mapping. Is it correct, that I have to user server-side fetch mode, when I want to use the POST request method?
Thanks ahead,
Bernd

Yes.

Have a look at System Administration - System Configuration - Service Configuration - Applications - com.sap.portal.ivs.httpservice
This is used to do the Server side fetch.

Client Eventing Problem with URL Iview

Hi,
I am new to EP and have a basic client eventing question. We are trying to integrate a URL Iview from a partner product with a standard Iview downloaded from Iviewstudio. This standard Iview is capable of handling client events from other Iviews in the standard package. We want to re-use this Iview with the same event (same functionality) to be able to handle events from the partner URL Iview.
The partner Iview and our portal are on different servers.
We are using the following Javascript but it doesnt seem to raise the event.
EPCM.storeClientData('urn:com.sap.bor:BUS0010','objid',LocId));
EPCM.storeClientData('urn:com.sap.bor:BUS0010','AllKeys','objid');
EPCM.raiseEvent('urn:com.sap.bor:BUS0010','select','','/irj/servlet/prt/portal/prtroot/...'
We were able to debug and find that the data was being stored in the Data Bag. However the event is not being raised at all. It seems that it just gets stuck somewhere in the Raise event. We even put a javascript alert after the raise event but it doesnt seem to reach there at all.
Could you give me a few pointers as to what the problem might be.
Thanks in advance.

Hi,
let's have a look at two quotes of the PDK documentation.
"Using the EPCF from your JavaScript, you can send messages to JavaScript code embedded in other iViews."
"Isolated iViews are iViews that are not inlined into a portal page, but referenced using an IFRAME. To make the EPCF available in such iViews, the EPCF JavaScript as well as the EPCF applet are included into each generated frame."
From my point of view, this only can work automatically with content provided by the portal.
Therefore, this can't work with isolated URL iViews generated with the wizards. Imagine a google iView, running in an iFrame. Google is called by the portal, but it's simply standard google HTML output - displayed in the portal.
To provide the capability of the EPCF, the epcf javascript file has to be included in the "partner URL iView"'s source. I tried this and it worked. However, this is not a highly sophisticated solution
If the partner iView's server is running in a different domain, there are further issues to be considered (keyword: java script origin policy)
If anybody has corrections or can provide a good solution, don't hesitate.

Problem with URL encoding conversion

Hi all,
I am working on an I18N application and in my application one component sends the request to another component and then this component fetch that requet and extract the query-parameters from the request (HTTP request).
Now the problem is that the input to first component can be given in one of the 5 character encodings:-
UTF-8
Shift_JIS
EUC_JP
Windows-31J
ISO-2022-JP
I have created a test program that convert the encoded URL from one character encoding to another character encoding. It is working successfully for the above 4 encodings but for the last encoding that is "ISO-2022-JP" this fails. The test programs is: -
import java.io.*;
import java.util.*;
import java.net.URLDecoder;
import java.net.URLEncoder;
class JPtoUTF8{
     public static void main(String[] args){
          try{
              String shift_jis = "%82%C8%82%A4%82%8B%82%E8";          // This is Shift_JIS encoded URL
              String iso2022jp = "%1B%24B%24J%24%26%23k%24j%1B%28B"; // This is ISO-2022-JP encoded URL
              String utf8 = "%E3%81%AA%E3%81%86%EF%BD%8B%E3%82%8A";   // This is the result that should be obtained
              String decodedShift_jis = URLDecoder.decode(shift_jis,"Shift_JIS");
              String decodedIso2022jp = URLDecoder.decode(iso2022jp,"ISO-2022-JP");
              String encodedShift_JIS = URLEncoder.encode(decodedShift_jis,"UTF-8");
              String encodedIso2022jp = URLEncoder.encode(decodedIso2022jp,"UTF-8");
               System.out.println("shift_jis        = "+shift_jis);
               System.out.println("encodedShift_JIS = "+encodedShift_JIS);
               System.out.println("iso2022jp        = "+iso2022jp);
               System.out.println("encodedIso2022jp = "+encodedIso2022jp);
          }catch(Exception e){
               e.printStackTrace();
}I am using jdk5 for this application.
Please give your valuable suggestions.
Thanks in advance.

Could the cause be that ISO-2022-JP is not just ISO-2022-JP:
http://www.w3.org/TR/japanese-xml/#AEN28427904
Maybe what you are getting is one of the flavors, while the java urldecoder uses another flavor? Or maybe the string you are getting is incorrectly encoded to being with (might have been incorrectly converted from shift-jis)?
With the shift-in shift-out design it is a difficult encoding to deal with under the best of circumstances, so you have my sympathy.

Problems with URL in CS5

Hello, all. I'm having a simple but very frustrating problem in Flash CS5 with Actionscript 3. I'm trying to set up a link in an image, when you mouseover the image, it says video and I want to be able to click on it and have it lead to a new URL. I've gotten the swinging right and have tried (what seems like) every actionscript code out there. Currently I have:
/* Click to Go to Web Page
Clicking on the specified symbol instance loads the URL in a new browser window.
Instructions:
1. Replace http://www.adobe.com with the desired URL address.
Keep the quotation marks ("").
help_btn.addEventListener(MouseEvent.CLICK, fl_ClickToGoToWebPage);
function fl_ClickToGoToWebPage(event:MouseEvent):void
navigateToURL(new URLRequest("http://www.adobe.com"),
"_blank");
Which is the basic code snippet, but it won't load adobe.com or any other site and doesn't show any error messages. Might anyone have any thoughts or suggestions?
Thank you in advance,
Katie

You could look in the help, as you need to learn to use trace - it's very useful for debugging. That being said - you just do like:
function fl_ClickToGoToWebPage(event:MouseEvent):void
trace("fl_Click was called successfully");
navigateToURL(new URLRequest("http://www.adobe.com"), "_blank");
If the function is called, you will see the text appear in the Output window.

Problems with url-bindings when redeploying on Oracle 9iAS

Hello!
I'm working on a project where we're having a development server that runs Oracle 9iAS (9.03). This server is used both for system-testing and for continuous integration using Cruisecontrol. The application that we deploy is an ear-application with several web-applications and ejb-components. We have in order to make these two deployments work together defined two different application servers on the console and deployed on both of them. We have also specified prefixes, like /cc/ on the url-bindings so that we can access all the web-applications.
Our problems usually arise when Cruisecontrol does a redeploy of what it has built before it's going to test it. It uses dcmctl for this and it usually runs successfully, but sometimes the application server resets the url-bindings so that all the web-applications go to the root. Other times it removes the whole application and I've even seen it show out-of-memory errors even though it still has about a gigabyte of memory available. I don't think this is related to that single server because I've seen the same thing happening on our production-server the first time I was going to redeploy through the console-application.
Have anyone else had the same problem? (...and hopefully found a solution to it?)
It's quite annoying for us because this screws up Cruisecontrol for us at least once a day and I'm not sure how good this is for a production environment.
Regards,
Bjorn Vidar Boe

Does anybody know if Financial Brokerage Service(FBS) can be deployed on Oracle 9iAS using OEM. I got the following error when I tried to deploy the ear file:
Deployment failed: Nested exception Root Cause: Error loading web-app 'ibfbs-web' at C:\Ora9ias\j2ee\FBS\applications\ibfbs\ibfbs-web: Unknown assembly tag in file:/C:/Ora9ias/j2ee/FBS/applications/ibfbs/ibfbs-web/: <ejb-local-ref>; nested exception is: java.lang.InstantiationException: Error loading web-app 'ibfbs-web' at C:\Ora9ias\j2ee\FBS\applications\ibfbs\ibfbs-web: Unknown assembly tag in file:/C:/Ora9ias/j2ee/FBS/applications/ibfbs/ibfbs-web/: <ejb-local-ref>.

Thanks ! Hi -
Can you check and see what version of 9iAS are you using?
The ejb-local-ref tag is a new tag introduced in the J2EE 1.3 specification - so you will need to be using the Oracle9iAS v9.0.3 release which is J2EE 1.3 compatible.
If you are using the v9.0.2 release then you will need to upgrade to v9.0.3

Problem with URL parameters& Forms

First off, this is a school assignment so I am not looking for code, just suggestions. I e-mailed my prof, but she hasn't gotten back to me.
I have a nim program, that game where you pick matches up till someone picks up the last match wins. I need to change the program so that it accepts a variable integer to change the starting number of matches. I opted to use a form, but this has gotten me into some trouble. My prof. used url parameters to determine who should go first, the human or the computer.
Basically, I need to submit the variable in order to post the number, but I also need to redirect depending on who goes first.
This is what she did with the URLS:
    [<a href="<%=root%>/StartServlet?first=computer">Computer</a> (that's me!)]
    [<a href="<%=root%>/StartServlet?first=human">Human</a>]My form is just a simple, standard form at the moment:
    <form name="input" action="<%=firstMover%>" method="post">
        <input type="text" name="matches">
        <input type="submit" value="Submit" name="Submit" />
    </form>Variable Retrieval:
        match= request.getParameter("matches");
        matchCount= Integer.parseInt(match);There is a lot of code associated with this program. So if you need more please just ask.
Any suggestions are greatly appreciated as I have no idea...

That might work, but I need to allow the user to choose who goes first, computer or human. I'm not sure if I can do that with a hidden form. (Maybe I am just not seeing it the way you are.) Also, she analyzes whether the person chose computer or human first in the startservlet class. It looks like she parses the URL there and grabs the parameters.
Your suggestion gave me an idea... but I can't get the program to recognize my variable. I don't think I am sending it to the right place.
Form:
<form name="input" action="<%=root%>/StartServlet?" method="post">
        <input type="text" name="matches">
        <select name="firstMove">
            <option value="Computer" checked>Computer</option>
            <option value="Human">Human</option>
        </select>
        <input type="submit" value="Submit" name="Submit" />
    </form>    My request of parameters:
public class StartServlet extends HttpServlet {
    /** Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
    * @param request servlet request
    * @param response servlet response
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        String match= request.getParameter("matches");
        int matchCount= Integer.parseInt(match);
        Nim nim = new Nim(matchCount);
        HttpSession session = request.getSession();
        session.setAttribute("nim", nim);
        String first=request.getParameter("firstMove");
        if ("computer".equals(first)) {

Problem with URL

Why the VM tells me a error when executing the code below?
It says "java.lang.NullPointerException at javax.swing.ImageIcon.<init>(ImageIcon.java:138)".
But the file path is correct and the file exists!
Whats the problem?
<code>
import java.net.*;
import java.awt.*;
import javax.swing.*;
public class Freq extends JFrame
     public Freq()
          this.setSize(300, 200);
          URL url = this.getClass().getResource("file:///Programme/eclipse/workspace/OktaShop/ImportGUI.gif");
          ImageIcon icon = new ImageIcon(url);
          System.out.println(url.getProtocol());
          System.out.println(url.getHost());
          System.out.println(url.getPath());
          Container container = this.getContentPane();
          JButton btnIcon = new JButton(icon);
          container.add(btnIcon);
     public static void main(String args[])
          new Freq().show();
</code>

P.S.: I also tried "file:///C:/Programme/eclipse/workspace/OktaShop/ImportGUI.gif"
No success as well.

Problem with URL in InDesign to PDF

I have two weblinks in my InDesign document.
When I output to an interactive PDF and open in Adobe Reader, the link is there but I get a message that "Acrobat does not allow connection to [URL]"
I have a clickable link in the document, then I right-click on it and in the interactive box do "Add URL" I've done it several times, so I'm confident the URL is correct; one of them is my own website.
What am I doing wrong?

Many thanks for the very detailed instructions.
However, I'm opening this in Adobe Reader — I wouldn't expect that the people I'm sending this to would have or know how to use Adobe Acrobat.
I did open it in Acrobat Professional and it asked me if I wanted to allow the connection — when I clicked yes, it went to the website. BTW, it's a link to allow people to download Adobe Reader — it's very annoying that this PDF won't open properly and play the video in Quicktime player on the Mac (which is what all of the people I'll send this to are using).
So your thought was right on the money, but it still doesn't work in Adobe Reader, which is the only way anyone can read this document. Ironic that the only link I really need is one for them to obtain Adobe Reader and yet, Adobe Reader won't allow them to use the link!
