Monitoring hyperlink activity through applet

Is it posible for an applet to monitor which hyperlinks are being click on by the user in a different frame? I could not find a documentatioon on this, maybe i am blind...
Thanks for your help,

Thanks for the reply, thats what i did.

Problem selecting and dragging or moving an object with hyperlink activated

Hei!
It is impossible to select or move normally an object, for instance a photo, which contains an activated link, and that's very annoying.
First: Let's say I have that object on the top of the page and I want to put it lower, or maybe cut it and paste it somewhere else. First I need to select it, but as soon as the mouse is on top of it, the mouse over activates and opens a webpage to the designated link.
Second: before I do anything with it, I need to select the object and the only way to do it is by drawing a selection rectangle, which gives me the problem of needing to avoid surrounding objects which I don't want to select. If I don't have space enough, I have to let them get selected together with the desired object, and then unselect using the command key + mouse click.
Third: if I want to move it, i can only do it with the arrow keys, because if I use the mouse, I get back to first problem. So it's that, or disabling the hyperlink, move the object normally, and putting the hyperlink on again. None of it very practical.
If I actually want to cut the object and paste it in another page of the site, after I went through first and second problem, I can cut normally the object, got to the desired page and paste it there. If once there I still need to move the object to place it where I want, I end up in third problem anyways.
Is there any way to avoid this trouble?
Thanks

Thanks Mark, but you answered what I already included within my question. I wrote "So it's that, or disabling the hyperlink, move the object normally, and putting the hyperlink on again"
With that, to "Uncheck the "Make hyperlinks active" you need to first select the object, and you end up back to the first and second problem I wrote.

Hyperlinks from an Applet

Hi,
I was wondering if we can have hyperlinks in the applet. I have a Table which has 6 columns and some thousands of rows of data. I want to provide hyperlinks for each row in the first column. Is there any way that i can do it. I tried searching in the forum theards but could not get a clue on how i should be doing it.
I'm new to java..! Please help..
Thanks

here is the basic of it compile the code an try it

Hyperlink in an Applet

Hi,
is it possible to create a hyperlink in an Applet?

Give your button an actionlistener then once it's clicked run this bit of code where target is a String such as "_blank" which will determine where the link should be shown
getAppletContext().showDocument(new URL("http://www.example.com"), target);

Problem in printing to LPT1 through applet?

Hello everyone,
I am having problem in printing through Applet in LPT1 of remote client machine using "gridDoubleClicked" method of customized "GridPanel" which is third party component. The class structure is given below:
public class GridPanel extends Panel implements GridPanelInterface, AdjustmentListener, KeyListener, FocusListener, Serializable
}I am using above class to populate data in table and perform "double click" action. I am using JDK 1.5 and a self signed jar to access from remote machines through applet.The code, I am using is given below:
public class testApplet extends Applet {
    printToLPT1 lpanel =new printToLPT1();
    public void init() {
      this.setLayout(new BorderLayout());
      this.add(lpanel, BorderLayout.CENTER);
      this.setSize(380, 250);
public class printToLPT1 extends Frame{
GridPanel grid;
public printToLPT1() throws Exception {
grid.addGridListener(new GridAdapter() {
            public void gridDoubleClicked(GridEvent ge) {
                testPrint();
public static void testPrint() throws Exception {
        try {
            BufferedOutputStream pos = new BufferedOutputStream(new FileOutputStream("LPT1"));
            String str = "\n\n\n\n\n\n\n\n\n\n\n";
            pos.write(str.getBytes());
            pos.flush();
            pos.close();
        } catch (Exception fnfe) {
            throw new Exception("PRINTER SETUP IS NOT PROPER");
}For applet, I have used following script in login.html:
<APPLET
     height="200px"
     archive="testprinter.jar,jbcl.jar,grid.jar,plugin.jar"
     width="390px"
     align="top"
     code="test.testApplet.class"
     name="Testing"
    ALT="<P>This applet requires Java to be enabled! Check the browser options or see your SysAdmin." MAYSCRIPT>
    <P>This page requires Java! Get it free from <A HREF='http://www.java.com/'>www.java.com</A>.</P>
</APPLET>
------------------- If signed jar file of application is run using command line in client machine then "double clicked" of GridPanel method works fine and send signal to printer at LPT1 port but when same application is called using applet and accessed from remote machine with printer in LPT1 port, in that time also "double clicked" of GridPanel method works fine but printer could not be found and Exception is thrown java.lang.Exception:"PRINTER SETUP IS NOT PROPER" . Why is this happening? Can anyone suggest me the solution for this problem?
Thanks in advance.

Make Hyperlinks Active works on URL, not on PDF files

When I'm working on my site and click "make hyperlinks active" to test them, the link associated with a web page at another site on the Internet works, but the hyperlinks associated with pdf files I've selected on my computer don't work. I click and nothing happens.
When I check the files on the computer and just click on the they open fine. They won't work from iWeb, however, when I check make hyperlinks active.
When I uploaded the site, and tried to download the pdf files by clicking on the links on my site, some worked and some didn't. Some opened rather quickly, some took forever.
ANY AND ALL HELP IS APPRECIATED.
Rex

The link to a file doesn't work in the iWeb application
Publish your site to a folder on the desktop, launch it in your browser by double clicking the index.html file and click on your PDF link to see if it directs you to its location on your hard drive.
If it doesn't, you have not set it up correctly in iWeb.
If you are uploading to a server other than .Mac, open an appropriate page folder on your server using your FTP application to see if the PDF or Zip file is actually there.

Including hyperlink in the applet

how do can i include a hyperlink in the applet

hi there EXPERT
sorry for the question format.
Here is what i want to do!! Firstly i'm writing a converter
from some another lang. to Java. I'm implementing it using
the applets. That lang can include the "labels" as hyperlinks.
so if there are lots of labels, i need to find out whether it
is associated with a url or not and make that label a hyperlink
accordingly. so what this means i need to add the hyperlinks
to the applet as and when there are "url labels" in the other
lang window.
following is a simple applet,plz explain me how to add hlinks
to it.
import java.awt.*;
import java.awt.event.*;
import java.applet.*;

Try all that in that same order, and test it afterwards.
Hope that helps

There should be a lesson about this somewhere.
When you visit a web page, does it ask you if you want to have an applet loaded?
Answer: No
So, if you visit a page, and an applet is silently loaded which can then execute commands on your computer, is this good?
Answer: No
So why do you want to do this?
Is it good for anyone?
I mean, if I want to do "ls", can't I just open a command line? Do I need an applet to do it for me?
Either you have devious desires or your hacking together something that probably shouldn't be.

In contrast to what many people say in this forum, it is possible to have an unsigned applet access a database. You don't even have to manipulate the client's policy-file. The requirement is that the database is located on the same machine as the applet is downloaded from.There are however other things that can break this possibility. One is the database-driver itself.
In the case of Oracle we have tried using different versions of the driver. When using version 8.1.7 or 9.0.1 things work nicely, but when switching to version 9.2 it stops working. There is a question on OTN [1]. Let's see what Oracle has to say about it.

Database Connection through Applet

Hello All,
I want to connect to Access Database through Applet. But I am getting access denied error. How to allow an Applet to connect to the database ?.
Waiting for reply.
Thanks and regards,
Sachin

I believe it's possible to change the security policy for the java plugin that runs applets, (though I haven't found an appropriate policy file). However, there seems little point in writing an applet that requires that. The whole point of applets is that anyone can run your applets over the net without any special installation. If whoever is going to run your applet has to muck about with security policy files, they'd be a lot better off just running a stand-alone GUI program.
Even if you signed the applet there would still be the problems associated with having the access file in the right place on the client machine.
In short you're falling between two stools. Either make the thing a standalone Swing program and install it alongside the database it accesses or do the database access in a web server environment and have the client side obtain the data from the database through http access.

How i use OEM 12c to monitor Microsoft Active directory.

Hi,
How i use OEM 12c to monitor Microsoft Active directory.Please assist me on this.
Thanks,

Hi,
The fundamental problem with this scenario is that you have non-failover capable modules in a failover chassis - think of the ASA failover pair as one device and the IPS modules as two completely separate devices.
Then, as already mentioned, add only the primary ASA. (The secondary will never be passing traffic in standby mode so it's not actually needed in MARS) Then, with the first IPS module you can add it as a module of the ASA or as a standalone device (MARS doesn't care). With the second IPS module the only option is to add it as a separate device anyway.
In a failover scenario the ASA's swap IP's but the IPS's don't so whereas you'll only ever get messages from the active ASA you'll get messages from both IPS IP's depending on which one happens to be in the active ASA at the time.
Don't forget that you have to manually replicate all IPS configuration every time you make a change.

Connectivity of database through applet

Hi to all,
I want to how to make the connectivity of database(preferably mySql) to java application through applet....

Possible answers to a more focused question:
Make sure the jar file containing the JDBC driver is in your applet's classpath.
Read the JDBC tutorial.
Make sure that the network connectivity between your client and the database is working.
Any of those sound right? No? Want to ask a more specific question?
