ScrollPane in Netscape

Hi,
I have a Java Applet with a scrollpane. There is a panel inside this scrollpane. The scroll bars work fine when I open the netscape browser for the first time. But when I reload the same page, although the bars appear but they don't move on mouse clicks.( I can scroll vertically using the middle mouse button only). But this applet works fine in IE.
Any help/suggestions would be greatly appreciated.
Thanks

most Browsers run java pretty badly
there is what happened when i tried to find a browser that could handle my app:
iCab doesn't stop firing keypressed events that were not pressed ( ??? )
Explorer works fine but takes 2 minutes to load what others load in 5 seconds
Netscape didn't open it at all
Safari worked just fine but is mac only ( apple really does great efforts to support java )
that's all
if the bug doesn't appear if you launch the applet in an applet viewer rather than in a browser then i don,t think there's much to do
sorry

Netscape and SSO to partner application

Help!
I have a partner Java app using SSO with a custom login form. All is well in IE 6 but I get problems with Netscape 7.
It authenticates to the Portal OK, but not to the partner app.
The browser displays the following message:
Oracle SSO Failure - Unable to process request
Either the requested URL was not specified in terms of a fully-qualified host name or OHS single sign-on is incorrectly configured.
In the http server error log is the message:
[OSSO] W05: Requested URL is not specified in terms of fully-qualified host name or invalid SSO partner configuration. Host from request kwudeal2.nkw.ac.uk:80, registered host kwudeal2.nkw.ac.uk.
The obvious difference in the host names is the port 80, which is the correct port, but it wasn't in the URL I followed, Netscape appears to have added it.
Any ideas about what is going on and how to fix it?
Is anyone using Netscape 7 with SSO?
Thanks. Rob

Here's a DIY answer.
See Metalink Note 269820.1 which shows you how to use Perl to overwrite the host name in the HTTP header and remove the port number.

The three ACIs listed below need to be present in the Directory Server in order
for Calendar server to work properly. Check the properties on the Base DN to
verify that the following ACIs exist. If they are not present, you will need
to add them, and the Base DN will need to be modified for your enviroment.

Hi Trinidad,
Thanks for your help!!!
1.
I didn't install EventSender and DIProxy yet, I tried first to upload and deploy the zip files, but I couldn't open the Itegration Application Explorer.
2.
The jvm.dll file is in in the folder pointed by the logs: C:\Program Files (x86)\SAP\SAP Business One Integration\jdk1.5.0_xx_sap\jre\bin\server
and it is also in C:\Program Files (x86)\SAP\SAP Business One Integration\jdk1.5.0_xx_sap_64\jre\bin\server
I tried running the file java5w.exe, but I got an error message:
Access is denied
Unable to open the service tomcat5
Thne I managed to open it by "rua as administrator".
the Java Virtual Machine path is points to the java 1.5 version folder.
Is it possible that the reason that the service can't start is related to administrator rigts??
In the properties in the Integration Service (services.msc):
It is set to be run with the local system account.
all other properties looks fine.
in the properties of the tomcat5.exe (and tomcat5w.exe , I tried both)
In the Compatibility tab I tried setting the flag "Run this program in compatibility mode for" to Vista, windows 7, and server 2008
I didn't have the option of Windows XP.
I have also set the Privilege level of: "Run this program as administrator" to true.
But still the service won't start.
What can be the problem?
What else can I check?
Thanks a lot,
Chana

Custom graphics in java.awt.ScrollPane

Hi all,
I have to draw a custom created image in a scroll pane. As the image is very large I want to display it in a scroll pane. As parts of the image may change within seconds, and drawing the whole image is very time consuming (several seconds) I want to draw only the part of the image that is currently visible to the user.
My idea: creating a new class that extends from java.awt.ScrollPane, overwrite the paint(Graphics) method and do the drawings inside. Unfortunately, it does not work. The background of the scoll pane is blue, but it does not show the red box (the current viewport is not shown in red).
Below please find the source code that I am using:
package graphics;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.ScrollPane;
import java.awt.event.AdjustmentEvent;
public class CMyComponent extends ScrollPane {
 /** Listener to force a component to repaint when a scroll bar changes its
 * position.
 private final class ScrollBarAdjustmentListener implements java.awt.event.AdjustmentListener {
 /** The component to force to repaint. */
 private final Component m_Target;
 /** Default constructor.
 * @param Target The component to force to repaint.
 private ScrollBarAdjustmentListener(Component Target) { m_Target = Target; }
 /** Forces to component to repaint upon adjustment of the scroll bar.
 * @see java.awt.event.AdjustmentListener#adjustmentValueChanged(java.awt.event.AdjustmentEvent)
 public void adjustmentValueChanged(AdjustmentEvent e) { m_Target.paint(m_Target.getGraphics()); }
 public CMyComponent() {
 // Ensure that the component repaints upon changing of the scroll bars
 ScrollBarAdjustmentListener sbal = new ScrollBarAdjustmentListener(this);
 getHAdjustable().addAdjustmentListener(sbal);
 getVAdjustable().addAdjustmentListener(sbal);
 public void paint(Graphics g) {
 setBackground(Color.BLUE);
 g.setColor(Color.RED);
 g.fillRect(getScrollPosition().x, getScrollPosition().y, getViewportSize().width, getViewportSize().height);
 public final static void main(String[] args) {
 java.awt.Frame f = new java.awt.Frame();
 f.add(new CMyComponent());
 f.pack();
 f.setVisible(true);
}

Dear all,
I used the last days and tried several things. I think now I have a quite good working solution (just one bug remains) and it is very performant. To give others a chance to see what I have done I post the source code of the main class (a canvas drawing and implementing scrolling) here. As soon as the sourceforge project is accepted, I will publish the whole sources at there. Enjoy. And if you have some idea for my last bug in getElementAtPixel(Point), then please tell me.

}Ah, just to give you some idea: I use this component to visualize a hex grid map with more than 1 million grid elements. And it works, really fast, and requires less than 10 MByte of memory.

Couldn't you download the netscape.ldap package (iPlanet LDAP SDK) and put its jars in your app classpath?
The suggested way to replace netscape.ldap package is to use only JNDI calls, but maybe they can not fulfill all your needs.
By the way, you can get the source code for that package in Mozilla.org site.
(Note: if you are using Netscape LDAP SDK for parsing/generating ASN.1 streams including X.509 certificates, try using BouncyCastle instead of netscape.ldap.ber.stream package - I had to modify several classes from Netscape's package that is not meant to handle certificates, but LDAP streams...)

How to set up a Java Plug-in Download page in case of netscape?

hai all of you,
i have a problem regarding downloading plugin.
i am using <object > and <embed> tags to download the plugins inorder to run the applets. but it is taking long time to download the plugin form sun.com.
so what i have done is, i downloaded the plugin.exe file and .cab file and put it in my tomcat server mainted by other party.(y application if for internet purpose only.)
i refered to http://java.sun.com/products/plugin/1.2/docs/intranet.html. there it is mentioned that, to download the plugin.
for I.E i can able to change the code.
but for NetScape it's a little bit confusing.
i have downloaded the binary file in my own directory.
here he is asking to set up a java plugin-in download page.
instead of this "plugin-install.html" page what page i should create and what should be the code in this page if i have to write on my own. please let me know if anybody know about it.
following para is from sun.com
"To deploy Java Plug-in in intranet environments with Navigator, you need to download and store the Java Plug-in binary file on one of your web servers. Then you need to set up a Java Plug-in Download page and modify the pluginspage attribute in the EMBED tag to refer to this page. The Download page should have options to download different versions of Java Plug-in, such as for Windows and Solaris. For example, if you have set up the Java Plug-in Download page at "http://javaweb.eng/plugin/" and the page is called plugin-install.html, you can specify the pluginspage as "http://javaweb.eng/plugin/plugin-install.html". "
thanks

I have successfuly done this.
Change the converted html as per the instructions to point to another page.
Here is an example of the new html page you need to create:
<html>
<head>
<title>Java Plugin Install Page</title>
</head>
<body>
<h2><center>Java Plugin Install Page</center></h2>

<h3>Windows Version Only!!!</h3>
Click here to Download Plugin

You may or may not be asked to either save or run from current location
If the run from current location is available, use that option
If you can only save the file, then save it to your workstation and exit the download page and exit Netscape. Then using Windows Explorer, go to where you downloaded the file and double click on the file to run it. Accept all options during the install process and once it has finished try accessing your web page again using Netscape. You should then get to the web page or application and this page will not apppear again.
</body>
</html>
If you put the file j2re-1_3_1-win.exe on a web server somewhere then you will have to prefix the file with
http://yourwebserverdirectory/
Hope this helps.

Importing to Mac Mail Tiger 10.4.8 (intel xeon) From Netscape (7.2) mail

Importing to Mac Mail Tiger 10.4.8 (intel xeon) From Netscape (7.2) mail.
I can import old mail from Netscape 7.2 into Mac Mail Tiger 10.4.8. And most old mail back from 2002-2004 is imported but starting around MARCH 2005, no more mail is imported. That is out of 10-15 folders imported INTO the "import folder" each new folder contains, older mail but only a few from 2005, and nothing from after march 2005. (perhaps when switched from NS 7.1 to 7.2?? don't know) But in any case viewing with NS mail shows the files and attachments, but they DO not import to Mack mail. (one oddity when viewed in NS mail, if the priority column to be "normal" then they are imported. If empty then not imported.)
Any ideas how to get the rest of this mail into Mac Mail?
thanks

So NOW with all the data, properly in my Netscape Mail "local folders" I can easiliy (but slowly) convert them to Mac Mail.
Sorry for pulling the trigger too soon, It works perfectly if I use the proper backup data.
DUH! on me!

Urgent Help Required !!!! For using Netscape to open Form on the Intranet

Hi ,
I am successfully able to open Form application in a seperate window using IE 5.0.
I would like to do the same with Netscape Navigator 4.7. The Navigator justshows a page which asks me to download the plugin and then even after I install the plugin it does the same thing over and over again.
Please help !!!!!

Netscape 4.7 and duplicate cookies

I've got an application that works fine on IE and Netscape 6, but NS 4.7 is
          giving me a headache. I'm trying to expire the cookies that I've originally
          written with 1-year expiration date. I originally created the cookie like
          this:
          info = new Cookie("UserID", "Bob");
          info.setMaxAge(60 * 60 * 24 * 365); // One year
          info.setPath("/");
          response.addCookie(info);
          When I try to expire it using this:
          info = Utilities.getCookie(request.getCookies(), "UserID"); // Gets the
          cookie from the request structure
          if (info != null)
          info.setMaxAge(0);
          response.addCookie(info);
          it fails on Netscape (both versions); the cookie doesn't disappear, almost
          like it ignored it. When I changed it to this:
          info = Utilities.getCookie(request.getCookies(), "UserID"); // Gets
          the cookie from the request structure
          if (info != null)
          info.setValue("0");
          info.setMaxAge(3);
          response.addCookie(info);
          it works on Netscape 6 (the cookie is invalidated enough that the code works
          and will expire in a few seconds). However, on Netscape 4.7, nothing
          changes. So I did a little debugging and found that under NS 4.7, the
          request structure ends up with TWO cookies of the same name ("UserID") and
          two different values. The first being its original value and the second
          being the value I set above. Clearly, something's not right. Is it me? Is
          NS 4.7 just buggy? I'm stuck for an answer to this mystery.
          Thanks in advance for help,
          -- Andy.


Hi,
When using Micosoft's Internet Explorer web browser, version 5.0 is supported for end users only. For administrators, changes to the iPlanet Web Server Administration Server configuration can be saved only when using Internet Explorer version 5.5. with standard Encryption.

Design problem(split pane scrollpane Insets)

hi,
doing a exam simulator prgm
design is like,
Question (text area with scrollpane)
Answers (checkbox inside panel with scrollpane)
used split pane between qst and ans but big thick bar comes how to reduce size and it is not
moving.
used GridLayout for container and panel.
PROBLEM is how to leave space qst textarea appears from very left edge of screen how to leave some space
same prblm for checkbox they to appear extreme left on screen.

Put those components in a JPanel overwriting the getInsets() method like this:
JPanel cPane=new JPanel(){
    private final Insets _insets=new Insets(10,10,10,10);
    public Insets getInsets(){
        return _insets;
};...should do the trick, take a look at the Insets class if you need information on how defining it...

Problem with Sessions, Servlets, Netscape and Solaris

We are experiencing a problem that is confounding and frustrating us (I have
 a felling that it is something exremely minor that we are overlooking).
 Here goes:
 Context:
 The problem only occurs when using a netscape browser against weblogic
 4.51running on our Solaris 7 box (Everything works fine through IE, and
 through both browsers against our development machines which are on NT)
 Problem:
 We have a bunch of JSP pages and servlets that are used togehter throughout
 our site. They both manage session information for the user. What is
 happening is that there is no problem maintaining session information among
 all the JSP pages, but when we hit a servlet that we use to stream graphs
 back to the browser, it gets the session but it has no contents all of a
 sudden. What seems to be even more strange is that the session is not
 tagged as new (by checking isNew()), it is just empty of the contents that
 were placed it by the JSP pages. Again, this is only occurring from
 Netscape browsers against our Solaris server.
 If anyone can provide any help it would be greatly appreciated. I can
 provide more details if need be.
 Jeremy


There is a property in the weblogic.properties file that lets you set
 the cookie name. If this isn't set, the port will be appended as part of
 the name. I've had a similar problem switching between http and https
 and losing sessions.

Problem with ScrollPane and JFrame Size

Hi,
The code is workin but after change the size of frame it works CORRECTLY.Please help me why this frame is small an scrollpane doesn't show at the beginning.
Here is the code:
import java.awt.*;
public class canvasExp extends Canvas
     private static final long serialVersionUID = 1L;
     ImageLoader map=new ImageLoader();
    Image img = map.GetImg();
    int h, w;               // the height and width of this canvas
     public void update(Graphics g)
        paint(g);
    public void paint(Graphics g)
            if(img != null)
                 h = getSize().height;
                 System.out.println("h:"+h);
                  w = getSize().width;
                  System.out.println("w:"+w);
                  g.drawRect(0,0, w-1, h-1);     // Draw border
              // System.out.println("Size= "+this.getSize());
                 g.drawImage(img, 0,0,this.getWidth(),this.getHeight(), this);
                int width = img.getWidth(this);
                //System.out.println("W: "+width);
                int height = img.getHeight(this);
                //System.out.println("H: "+height);
                if(width != -1 && width != getWidth())
                    setSize(width, getHeight());
                if(height != -1 && height != getHeight())
                    setSize(getWidth(), height);
}I create frame here...
import java.awt.*;
import java.awt.event.*;
import javax.swing.JFrame;
public class frame extends JFrame implements MouseMotionListener,MouseListener
     private static final long serialVersionUID = 1L;
    private ScrollPane scrollPane;
    private int dragStartX;
    private int dragStartY;
    private int lastX;
    private int lastY;
    int cordX;
    int cordY;
    canvasExp canvas;
    public frame()
        super("test");
        canvas = new canvasExp();
        canvas.addMouseListener(this);
        canvas.addMouseMotionListener(this);
        scrollPane = new ScrollPane();
        scrollPane.setEnabled(true);
        scrollPane.add(canvas);
        add(scrollPane);
        setSize(300,300);
        pack();
        setVisible(true);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    public void mousePressed(MouseEvent e)
        dragStartX = e.getX();
        dragStartY = e.getY();
        lastX = getX();
        lastY = getY();
    public void mouseReleased(MouseEvent mouseevent)
    public void mouseClicked(MouseEvent e)
        cordX = e.getX();
        cordY = e.getY();
        System.out.println((new StringBuilder()).append(cordX).append(",").append(cordY).toString());
    public void mouseEntered(MouseEvent mouseevent)
    public void mouseExited(MouseEvent mouseevent)
    public void mouseMoved(MouseEvent mouseevent)
    public void mouseDragged(MouseEvent e)
        if(e.getX() != lastX || e.getY() != lastY)
            Point p = scrollPane.getScrollPosition();
            p.translate(dragStartX - e.getX(), dragStartY - e.getY());
            scrollPane.setScrollPosition(p);
}...and call here
public class main {
     public main(){}
     public static void main (String args[])
         frame f = new frame();
}There is something I couldn't see here.By the way ImageLoader is workin I get the image.
Thank you for your help,please answer me....

I'm not going to even attempt to resolve the problem posted. There are other problems with your code that should take priority.
-- class names by convention start with a capital letter.
-- don't use the name of a common class from the standard API for your custom class, not even with a difference of case. It'll come back to bite you.
-- don't mix awt and Swing components in the same GUI. Change your class that extends Canvas to extend JPanel instead, and override paintComponent(...) instead of paint(...).
-- launch your GUI on the EDT by wrapping it in a SwingUtilities.invokeLater or EventQueue.invokeLater.
-- calling setSize(...) followed by pack() is meaningless. Use one or the other.
-- That's not the correct way to display a component in a scroll pane.
Ah, well, and the problem is that when you call pack(), it retrieves the preferredSize of the components in the JFrame, and you haven't set a preferredSize for the scroll pane.
Please, for your own good, take a break from whatever it is you're working on and go through The Java™ Tutorials: [Creating a GUI with JFC/Swing|http://java.sun.com/docs/books/tutorial/uiswing/TOC.html]

Problem with drawing in a scrollpane using clipbounds

Hello
Setup is a JFrame containing a splitpane with on the left just some config buttons and on the right a scrollpane.
Inside the scrollpane I want to draw big waveforms.
This is represented by a long array of 1's and 0's for the Y coordinates.
On drawing in paintComponents method I allways reconstruct a GeneralPath, based on the Clipbouns returned by the Graphics variable.
I have to reconstruct the GeneralPath polygon because my data can be millions long. And therefor I have to limit the points that are drawn.
When I allways reconstruct this GeneralPath, upon scrolling the polygon is shown scrappy, as in the line connecting the points will only be half shown or almost not.
Resizing the window or just minimize maximize and it is shown ok.
I do not have this problem when the GeneralPath I construct is only once made upfront and never remade in the paintComponent method.
But as I need the clipbounds to know which part to construct I need to rebuild this polygon over and over again.
I have tried to draw it with Line2D.Double but I get almost the same effect, parts of the lines not being drawn ok.
Below is the code of the Panel inside the ScrollPane responsible for this drawing.

My web site has a link which automatically configures an email. Doesn't work in Firefox 5.0 but OK in IE 8, Opera and Netscape. v

My web site is generated by Second Site , author John Cardinal, and contains email links which when selected automatically createsan email which all you need to do is fill in the body and send it. This has worked in the past in Firefox and does work now using IE 8, Opera, and Netscape browsers but does not work when using my Firefox browser neither locally on my computer or in my Internet website. Firefox is my browser of choice. This has worked in the past using Firefox.
My web site is www.schulteis.com/omnibus/. On the presentation page, on the bottom, where it identifies Genealogist: Site Administrator. Select it and it may work for you. John Cardinal tested it on his local machine and it worked for him. His response to me was,
"It's very likely that this is some sort of browser configuration error, and it's probably related to using a web-based email client, In
Firefox, look under Options > Applications and see how the "Mailto" Content type is configured. It should probably say "Use Yahoo Mail" [it does]. I have never configured a browser to use a web-base email client, so I can't help more than that.
Since this works fine on my computer and on my Internet site when using browsers IE 8, Opera, and Netscape but not Firefox, and I didn't do anything special for any browser to cause it to work, don't know what I could have done wrong for Firefox.
I am using Yahoo mail.
Thanks for your help

I'm also running FF 36.0.4 on a Win 7 machine. Here is what I see when I "open" the map (from the server - not inside DW):
The map area stays white with no image even after several minutes. The cursor does change to a hand when over the area where the map should be and if I click and drag there the cursor switches to the closed hand - so it's acting like the map is there and can be moved - but just no map shows up.
I'll run it though the validator. Thanks!

JScrollpane does not work properly when I interlinked to another Scrollpane

Hi,
I am trying to develop a small Editor using java Swing. I hav to display Line numbers also. for that i used another textarea and set the scrollbar model of that to the scrollbar model of text area where i type the programs. the module works perfectly in the first appearance.. scrolls same time..but the problem arises when i insert a new line into or delete a new line from the text area. when i am inserting or deleting the scrollbar of the prgram text area scrolls down immdtly after the insertion or deletion...
I tried a lot to solve the problem. Please help me...

I hav to display Line numbers ...Whatever component you use to display the line number you should add the component directly to the scroll pane that contains your main text area. You do this by using the scrollPane.setRowHeaderView(). I've posted several example of this if you search the forums.
