Java applet strang behavior

I am trying to run a java applet on the following site (not mine):
http://iaks-www.ira.uka.de/home/matteck/QuaSi/applet.html
The program seems to hang at some point, and I cannot kill the
java process because it doesn't seem to create one. To reproduce
the problem try the following:
Click the "Start Quasi" button. In the upper left window click
"Demo Circuits"->"Grover Circuit"
Then Click "Build this circuit".
A circuit should show up in the window. Try it a few times until it
doesn't show up (It seems to always fail at some point.).
If that doesn't work, navigate off the applet page and go back and
restart it. It seems to "crash" then.
Then try to kill the window without killing the browser--
I can't seem to do it because I see no java process in Task Manager, and
I cannot
Also, sometimes when I navigate off the applet page, the applet is still
running. I am not sure, but maybe this is only after it has crashed.
So, the two questions:
1) Can anybody see why it stops working? The Java console shows no
errors or anything.
2) Why is there no Java process?
Thanks,
Chuck.

Hold on, I now see an error:
AWT blocker activation interrupted:
java.lang.InterruptedException
     at java.lang.Object.wait(Native Method)
     at java.lang.Object.wait(Unknown Source)
     at sun.awt.AWTAutoShutdown.activateBlockerThread(Unknown Source)
     at sun.awt.AWTAutoShutdown.notifyThreadBusy(Unknown Source)
     at java.awt.EventQueue.initDispatchThread(Unknown Source)
     at java.awt.EventDispatchThread.run(Unknown Source)Not sure what the problem is, but it has crashed. For some reason if I
navigate off the page and back on, it still acts as if crashed. Also, the
window will not go away--no matter how I try to kill it, I cannot, unless I
kill the browser--actually all browsers, it seems.
So, what could be causing the crash, and why no java process?
I would like to use this applet in a talk I am giving next week, so I would
like to know it will work so I don't look like an idiot...

Problem Launching Java Applet with Plug-in: Version 1.4.2_01

Hello out there:
I recently installed j2re-1.4.2_01 on my home computer but have been unable to access Web sites emmploying JAva applets. The following is an email exchange with Jeff Hall of Lowell Observatory, manager of an educational site hosted by Lowell, trying to resolve my problem. The messages are better understood if read in reverse order.
I'm hoping that someone will recognize the source of my problem and can recommmend a solution. I would appreciate any help offered.
Thanks,
Mike Coucke
Hi Jeff:
Well, I guess the problem lies with me somewhere. Here's my answer/status to your questions/suggestions:
1) I'm using MS Windows Me version 4.90.3000
2) I do have the directory C:\Windows\.jpi_cache\jar\, but the only thing in it is an empty folder labeled "1.0". The file LP.jar does not exist anywhere on my hard drive.
3) I tried several game sites that utilized Java applets and got the same results: the Java cup in the upper left corner followed a few seconds later by the red "X". So, evidently the problem is somewhere on my end.
I'm going to post our email exchanges in a Java Users Forum managed by Sun to see if anyone out there can solve my problem. However, if you have any more suggestions, I'll be glad to try them.
Thanks for the help.

Mike,
Rats! What version of Windows are you using? It's a little strange to
see the user directory set to C:\Windows; if you're using XP, I'd expect
it to be something like C:\Documents and Settings\Mike Coucke. In any
event, the output that is of concern is these two lines:
java.lang.ClassNotFoundException: LPRemote.class
Caused by: java.net.UnknownHostException: proxy
It looks like your browser is not finding our server's IP when it comes
time to download the necessary Java code.
LPRemote.class is the fundamental code that runs LOPARC, and your
browser should be downloading it automatically when you click connect.
LPRemote.class is stored along with a bunch of other classes in a file
called "LP.jar" that you download from our server. So, if you go to C:
in Windows Explorer and do a file search for LP.jar, you should find it.
On my machine, it's stored in a directory called ".jpi_cache\jar\" in my
user home directory. Let me know if you have this file, or the
jpi-cache directory.
One other thing you might try is going to a different site that you know
uses Java applets -- I think some of the online game rooms at Yahoo use
Java. See if other sites that use Java load correctly. Then we'll know
if it's our server specifically, or a more general problem on your end.

Hello Jeff:
I still have the Java "blues". I followed your instructions, but am still unable to launch a LOPARC session. After an initial failure, I uninstalled all three Java versions I had (1.4.0, 1.4.1, 1.4.2), then reinstalled 1.4.2_01 from the Sun website.
Now, when I try to launch LOPARC, I initially get a blank window with the Java cup in the upper left corner. After about 20 seconds, the cup changes to a red "X". During those 20 seconds, the following appear in the IE message bar at the bottom of the window: "Applet LPRemote notinited" (their spelling) which changes to "Loading Java Applet Failed..." when the red "X" appears.
Following is a copy of the log from my Java Console during all of this:

Hi Mike,
Try it now. I think this problem has arisen because Sun just
released a new version of the Plug-in (1.4.2), and when we released the
public beta of LOPARC, only one relevant version (1.4.0) was available
and the LOPARC code was written to look for that by default. I have
just recoded the relevant routines so they should now cause your browser
to simply pick up the latest 1.4 version of the Plug-in you have
installed, whatever it is. I "broke" Java on my machine to replicate
your problem, and the code I inserted today did fix it. Hopefully it
will have the same effect for you. I am running IE 6 and plugin
1.4.2_01 (as accessed via Tools->Sun Java Console).
One broader problem: some (non-LOPARC-specific) users on the Sun
forums have reported the "JRE collision" you are seeing when multiple
versions of the Plug-in are installed on the same machine. So if the
fix I made to our code doesn't work, one option would be to uninstall
all Java components from your computer and do a fresh install of the
latest runtime environment.
Let me know how/if this works. Thanks for the feedback and for your
patience.
Best regards,
Jeff Hall

Hello Jeff:
So far, I have been unable to launch a LOPARC session. I repeatedly
get the following error message:
"Exception: java.lang.ClassNotFoundException: LPRemote.class"
My browser is MS Internet Explorer version 6.0.2800.1106 Initially I was
using Java Plug-In version 1.4.1 and received the error message. I went
to the Sun website and downloaded/installed Java Plug-In version 1.4.2
and still get the message.
Before I try to launch LOPARC, I can select Tools->Sun Java Console from
IE's pull down menu to check my Java Plug-In version. When I try to
launch LOPARC, I get the following message:
"Applet(s) in this HTML page requires a version of Java different from
the one the browser is currently using. In order to run the applet(s)
in this HTML page, a new browser session is required, press 'Yes' to
start a new browser session." If I select 'No', I get the following

If I select 'Yes', a new browser window opens and then I get the first

Dear Michael Coucke:
Thank you for registering with Lowell Observatory's online education
site. We hope you enjoy using it and visit regularly as we continue to
expand its features and capabilities. This is a one-time welcoming
email.
For your records, your user ID is xxxxx, and your password is #########.
You'll need to supply these each time you log in.
This site gives you access to research-grade equipment including a 16"
telescope, CCD detector, and image processing software. Our online
archive of data is now available 24/7. The telescope will be opening to
our onsite users in May, and on select nights to the Internet at large
in June.
We have designed this site so you don't need a huge monitor or a
supercomputer to use it. All pages are viewable on screens running at
800x600 resolution or higher. To use LOPARC, you'll need a Java-enabled
browser with the Java 1.4 plug-in installed. If you don't have the
plug-in, you'll be prompted to download it the first time you attempt to
connect. This is an admittedly large (9 MB) but one-time-only download.
This site works correctly under Internet Explorer version 5 or higher.
If you use Netscape, you must be running version 6 or higher, and
display or applet behavior anomalies may occur.
If at any time you can't connect to our server, simply try again later.
We do experience several power outages each year, particularly during
Flagstaff's summer thunderstorm season. Our server is fully protected
and backed up, and can be quickly brought back on line, but any active
user sessions will be lost. Thanks for your patience during these
inevitable downtimes.
Your questions, comments, suggestions, and bug reports about this site
are always welcome. On behalf of the LOPARC development team, thanks
for signing up!

Hi Mike,
I see this in your logs:
Java(TM) Plug-in: Version 1.4.2_01
Using JRE version 1.4.2_01 Java HotSpot(TM) Client VM
User home directory = C:\WINDOWS
Proxy Configuration: Manual Configuration
Proxy: http=proxy,https=proxy,ftp=proxy,gopher=proxy
Proxy Overrides:
I just helped my Dad set up his computer with a new
cable modem, and had the situation where we couldn't
access any secure Web sites. The cable folks had us
disable the proxy. It looks like the error message is
saying it can't find your proxy server, and the logs
you posted say that you've decided to configure your
proxy manually, rather than using the settings from
IE (which is how mine is set up in the plugin
control panel.)
Could that be the problem?

Java applet failures after updating to Java 6 Update 19

Hi,
I'm currently experiencing a failure of unsigned Java applets after upgrading to JRE/Plugin 1.6.0_19. The problem with the update has been narrowed down to an interim fix for a TLS/SSL Man-in-the-Middle attack (see http://java.sun.com/javase/javaseforbusiness/docs/TLSReadme.html). This fix intentionally fails attempted renegotiations.
The environment consists of Windows XP PCs running IE6/7 and JRE 1.6.0_19 as clients connecting to a website using SSL connections and SmartCard(PKI) authentication.
Previously, clicking a link on the website produced a new window to an URL with some HTML that uses an <APPLET> tag to open a Java applet. Prior to the applet loading, a Java "Request Authentication" dialog would pop up to allow selection of a certificate to be used for authentication from the browser keystore.
Now, no such dialog displays. And, depending on client and chosen applet, these responses are observed:
(1) complete failure of the applet to load with "java.lang.ClassNotFoundException" and "javax.net.ssl.SSLException: HelloRequest followed by an unexpected handshake message" errors in the console;
(2) the applet loads but is unable to read its data files with "java.io.IOException" and "javax.net.ssl.SSLException: HelloRequest followed by an unexpected handshake message" errors in the console.
Overriding the interim fix with "-Dsun.security.ssl.allowUnsafeRenegotiation=true" results in a return to normal operation, but our security team does not deem this override an acceptable solution.
Any ideas?
Eric

Thanks for the detailed log.
Your server requested a renegotiation, and as renegotiation is unsafe, the client refused to renegotiate the connection. That's the expected behavior.
However, it seems strange that the server send a incorrect block of data immediately following the renegotiation request. From the bytes, I don't known what was the data the server sent following the handshake message. It would be of help if you could load your another log with the debug enabled (javax.net.debug=all)and unsafe renegotiation enabled(sun.security.ssl.allowUnsafeRenegotiation=true).

Embedded Java applet no longer works correctly (works is old FFOX, Goggle Crome, etc.)

an embedded Java applet pops up a response box with success or failure on a dbms update. With FFOX(32) 8.x and 9.x running on win7 64, the response box is blank but it should always be either Success or Failed.
This works just fine in older FFox(with XP), Goggle Chrome(win7 64), etc.

Hi and Welcome to the Forums!
Anytime random strange behaviors creep in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
Best!

Firefox 4 on Windows Vista loads java applet for my MOO site then immediately closes Java Console, dumping me from the site, so I have had to go back to Firefox 3.6.17 which works fine

I have 32-bit Vista Business, with Firefox as my default browser. I recently upgraded to Firefox 4 and found that I can no longer access my VRoma MOO, which uses a Java applet to connect. I can connect to the site, but within 30 seconds the Java Console closes by itself (without my having done anything) and dumps me from the MOO. Following suggestions on this website, I uninstalled two earlier versions of Java which were on my computer and downloaded Java 6.0.25, the latest version. I also disabled previous Java Console extensions in the browser. None of this helped. I can stay connected with IE, and I can stay connected with Firefox 3.6.17, which I have had to install again. This is disturbing, because VRoma has many student users and I don't want them to encounter this problem if they are using Firefox 4.

Hello Andrew.
You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on.

"Class Formatting Error" in a java applet? (Solved)

(This problem is completely my fault and it would be hard to provide enough information to request and answer. Disregard this message.)
I've been developing a java applet to go on my website, but when running it tosses a "java.lang.ClassFormatError: rendering/ImageObserverClass" to the console. When I looked into the code I thought of java compliance levels. (Earlier I had to set Eclipse to a higher compliance level to make it accept new ArrayList<Renderable>();)
Is this not my problem? In my html code I have the following:
<applet
code="main/GalacticConflict.class"
codebase="code/"
width="640" height="480">
</applet>In Eclipse the program compiles and runs fine, so it most likely is a deeper issue. Thanks for any help!
EDIT:
Heh, that was stupid of me.... Just decided to try removing the <Renderable> from there, but it still doesn't work. The line number the console refers to is commented code, making it even more strange. If you have insight, feel free to post it here, but I'm going to make sure my new code is even being passed to my server properly.

EDIT2:
It appears to be an error with my copying process -- when I view the .html file with Firefox in the workspace folder, it works fine. Sorry for the trouble.

Java Applet painting broken in IE11 and Windows 8.1

When running a Java applet in Internet Explorer 11 window on Windows 8.1, JRE fails to repaint the viewport correctly when the web browser window is resized or scrolled. (assuming the Java Applet has display dimensions larger than the window, necessitating the need to resize or scroll host IE window). Webpage is displaying the java applet using any of OBJECT or EMBED tags.
This JRE behavior prevents the user from interacting successfully with the Java Applet (typically input data fields or click buttons in applet) should user need to resize or scroll the window.
This bug only occurs on IE11 on Windows 8.1 with JRE 7 and JRE 8 (include 8u31)
This bug does not occur on IE11 on Windows 7, IE10 on Windows 7 / 8 , Firefox on Windows 7 / 8 / 8.1 , Google Chrome on Windows 7 / 8 / 8.1
This bug has also been posted to the IE Feedback website since 2013 as we do not know if this is to be resolved by Oracle or Microsoft.
With the upcoming removal of Java Plugin support in Google Chrome, and, with this JRE bug (or incompatibility?) in IE11 Windows 8.1, this leaves only Firefox as the only usable web browser for Java Applets on Windows 8.1. Our customer base on Windows 8.1 is only using IE11 or Chrome.

I am seeing a minor issue with the timesheet grid after users are upgraded from IE8 to IE11.
We are using Project Server 2010 with SP1 and Oct 2013 CU.
When some users (using IE11) switches between filters or views in the Timesheet page, the grid shrinks making to content un readable. The only way to get it back is to refresh the page. After a refresh, the grid returns to normal size, but the pane
divider is too far to the left and always must be dragged to the right in order to see the task names in the left grid.

Safari 6.0.4 - java applet keeps running when not in use?

Mac OS X 10.7.5
Safari 6.0.4
all the latest updates (software) as of 4/27/13
Oracle's Java r 21 also installed (latest)
website: http://javatester.org/version.html
NOTE: I have seen this on more than 1 computer that the 1st time running the Java applet (after clicking on the plugin missing placeholder, the app appears to begin loading, but 'hangs' as far as UI is concerned, although it is using CPU and accessing the disk the whole time.
Refreshing the page then allows you to see the Oracle java version displayed in the pink box
However, what I notice is that if you enter a new URL and go there, blowing away the Java applet page, guess what's still running in the background (via Activity Monitor) "Java Applet - javatester.org", occupying memory and using some small CPU.
this seems like ridiculously bad behavior in general. Has anyone else seen similar issues? is this related to an outstanding memory leak (bigger problem) in Safari? Any way to get java to behave if you aren't possibly using an applet?
could it be lazy cleanup/garbage collection in Safari? meaning it might vanish from the process list at some indeterminate point in the future? closing the tab it was running on (before a new URL was loaded) outright doesn't seem to kill it.

I have not used Onyx recently, although i use a number of other utils, and reset safari periodically.
It seems that it may be a delayed garbage collection issue. If I leave it for a bit and then come back it seems that the process is disappearing. If I can isolate anything more reliably I'll post again, but for now I'm going to stop worrying about it.
It was lingering long enough I thought maybe was a leak, but i guess I'm just not patient enough...
Also, I haven't reliably reproduced the high CPU cycle / hung applet condition on the 1st load. that may be something that shouldn't be going on (regarding the new security around java probably) but low pain point once I reload the page and tell safari to let the app run all the time.
so just to recap
- looks like the applet persistence in the process table is a delayed disposal issue that eventually gets done
- hanging applet on 1st load post security patch may be something, but hitting cmd-R is a lot more satisfying than devoting a lot of time to tracking that down right now
thanks for your suggestion

Proxy Login Request on Java applets

• 10.4.5 Client
• Windows 2.3k ISA 2005 Proxy Server
• Users' fileserving to Win2.3k - ADmitMac for AD integration
The client is a test machine on which I build campus master NetInstall images. In my testing procedures I've come across a bizarre problem with Java in the browsers (IE, Safari, & FireFox).
We use ISA proxy server with web filtering, and users must authenticate to the proxy. On a new user's first use of any browser, the proxy username & password are requested, and the Add to Keychain checkbox is available. If the user checks the box, no further proxy login requests are made; the user's Keychain is updated with the proxy information.
On pages with Java applets, however, each and every applet will ask for a proxy login, but the login window does not offer a Add to Keychain checkbox! If a page has 15 applets on it, the user will be asked 15 times to authenticate against the proxy.
Naturally, this is a BIG problem, especially when several of the sites our teachers use in classes and labs contain many Java applets.
On the web, there is almost nothing concerning setting up Java with proxy servers, as all Apple Java from v. 1.4.2 onwards picks up proxy information from the system's network settings.
On the Apple Developer site, Tech Note QA1263 demonstrates a way of setting HTTPS proxy settings by entering text strings in the 1.3.1 and 1.4.1 Plugin Settings apps Java Runtime Parameters. The same capability exists in the J2SE 5.0 Java Preferences app, too. Unfortunately, the Java applets do not use HTTPS, so far as I can tell, so this remedy is useless.
Any clues I can pursue? Any help or fixes?
Thanks in advance!

After some more research with the J2SE 5.0 Java Preferences app, I turned on the Java console, booted Safari and went to my favorite Java applet - babynamewizard. This is the output of the console log. From what I can glean, the plug-in sees the proxy server settings as it should, and reports them.
In addition, the J2SE 5.0 Java Preferences app allows you to turn off all security settings. No change in behavior.

Strange behavior in a table with dropTarget and delete action

I am having a strange behavior in a table with drag and drop and action component to delete row.
Steps:
Drag the first row to the table and appears in the destination table (works well)
Select and change the value by 156, appears an error (works fine)
delete the row, the row disappears (works well)
Add the first row again and the value is 156 instead of 158 (why ????)
I guess the error is the deletion that is not correct, but do not know how?
Can anyone help?
I add the source code if you see where I'm wrong

+public void newvalue (ValueChangeEvent valueChangeEvent) {+

+RowExample example = (RowExample) endValues.get(0);+
+example.setValue(valorNumber);+
+example.setId(valorNumber.toString());+
+RichTable table = (RichTable)FacesContext.getCurrentInstance().getViewRoot().findComponent(id);+
+RequestContext.getCurrentInstance().addPartialTarget(table);+
+}+
Case 1
I drag the first row to the target table (ok)
The new row appears (ok)
Enter the value 77 in the InputText (ok)
id content and value change (ok)
Case2
I drag the first row to the destination table
The new row appears (ok)
Change the value of the first row by 80 (ok)
errors appears (by validator) (ok)
Enter the value 77 in the InputText (ok)
the id is changed but the value NO (*KO*)
I do not understand the behavior

Adding custom navigation rules results in strange behavior

Hello,
We'd like to add navigation rules to our application. To avoid post-JHeadstart-generation-steps we created an extra faces-config-custom.xml file which contains the navigation rules. When adding this file to the web.xml and run the aplication we encounter strange behavior
- Errors are shown in duplicate
- 'Transaction completed' messages are not shown
Try adding the underneath faces-config-custom.xml to a standard HR demo project and you will get the same behavior.
(1) What is the reason of this strange behavior?
(2) How can we add custom navigation rules, without having to do post creation steps?
Regards Leon

Leon,
When you perform a drag and drop operation, JDeveloper adds the following lines to the faces-config.xml:
<lifecycle>
<phase-listener>
Oracle.adf.controller.faces.lifecycle.ADFPhaselistener
</phase-listener>
</lifecycle>
However, JHeadstart uses its own subclass of ADFPhaselistener, and defines the lifecycle element in JhsCommon-beans.xml. Due to a bug in ADF, ADF does not look for the lifecycle element in other files than faces-config, and adds its own element in faces-config.xml If you remove these lines, everything works fine again.
To prevent this from happening again, you can move the following entry from JhsCommon-beans.xml to faces-config.xml:
<lifecycle> <phase-listener>oracle.jheadstart.controller.jsf.lifecycle.JhsADFPhaseListener</phase-listener>
</lifecycle>
And then make a custom template for JhsCommon-beans.vm where you remove this entry.

What I need for my application is the use case in useBinding1(), i.e., a BooleanBinding where several listeners are attached to. The problem is that I never get a callback in the ChangeListener if one of the RadioButton.selectedProperty() is changed.
Now I tried what happens if I use the same BooleanBinding for another binding to a property plus the listener, now the listener gets callbacks as expected! (see useBinding2() )
Than I thought may be Bindings must be bound in order to trigger listeners and tried useBinding3() where I bind the BooleanBinding to a new BooleanProperty, in this case the listener doesn't get callback anymore...
And now I'm very frustrated and hope that anyone out there can help me to understand this strange behavior.
Thanks a lot!

All these work just fine for me: the listeners are all called as expected. Note that the listener is only invoked when the value of the binding actually changes, which doesn't happen every time a radio button is pressed. (For example, if both buttons are unselected, the binding is false. If one button is selected, the binding remains false and the listener is not invoked. When the second button is selected, the binding becomes true, and the listener is invoked.)

Strange behavior of HtmlPanelGrid.getChildren().clear();

I have some problem, described in previous messages.
Investigating it, I found some strange behavior, which I cannot understand.
I builded a small application to isolate this strangeness.
There are two pages, first and second. There are hyperlinks from first page to second. Secon page serves as an indicator, that navigation was successfull. It is not so all the time.
There is a bean, which constructs a hyperlink at runtime and which contains my problem, as I think.
The config file is (header and footer skipped):
<navigation-rule>
<from-view-id>/welcomeJSF.jsp</from-view-id>
<navigation-case>
<from-outcome>select</from-outcome>
<to-view-id>/secondPage.jsp</to-view-id>
</navigation-case>
</navigation-rule>
<managed-bean>
<managed-bean-name>bean</managed-bean-name>
<managed-bean-class>Buggy.Bean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
One can see, that navigation is always controlled with the one constant string literal -- select. The bean is called just "bean" and it exists during a session.
First page is (header and footer skipped):
<f:view>
<h:form>
<h:commandLink id="link1" action="select" value="link1 (hardcoded)"/>
<h:panelGrid id="panel" binding="#{bean.panel}" columns="20" border="1" cellspacing="0">
<h:commandLink id="link2" action="select" value="link2 (hardcoded)"/>
</h:panelGrid>
</h:form>
</f:view>
One can see, that there are two hardcoded hyperlinks, one is inside the panelGrid, second is outside. Also it is seen, that the panel is binded with bean property as a whole.
The second page is just displaying a text to be sure the navigation occured.
Now the bean (header and footer skipped):
private HtmlPanelGrid panel;
public HtmlPanelGrid getPanel() {
return panel;
public void setPanel(HtmlPanelGrid panel) {
this.panel = panel;
Application application = FacesContext.getCurrentInstance().getApplication();
MethodExpression expr = application.getExpressionFactory().createMethodExpression(FacesContext.getCurrentInstance().getELContext(), "select", String.class, new Class[0]);
HtmlCommandLink link = (HtmlCommandLink) application.createComponent(HtmlCommandLink.COMPONENT_TYPE);
link.setId("link3");
link.setValue("link3 (softcoded)");
link.setActionExpression(expr);
panel.getChildren().clear();
panel.getChildren().add(link);
One can see, that a third (softcoded) hyperlink is added to the panel dynamically, with preliminary clearing panel content.
* STRANGENESSES *
1) despite the fact, that the panel is cleared prior to adding softcoded hyperlink, I CAN see it on the page (all 3 hyperlinks are seen)
2) in the debugger I can see, that while executing code, the children list is empty; this can mean, that the order of execution of the Jave code and JSP code is reversed; despite this fact, I see the hardcoded link BEFORE the softcoded
3) the link2 (hardcoded) is not work, i.e. it is not leads the second page to be displayed
4) if I comment the line panel.getChildren().clear(); then all 3 hyperlinks start to work

But when I put links creation code in bean's constructor, it was lost.
It seems to me, that the system creates panel independently and only after that calls setter of my bean. Ergo, the data from the panel field, initialized in constructor is overwrited.
Where I should place programmatic filling of panel element?

Strange behavior of email notification: where is the log?

Hi,
The email notifications have a strange behavior in our productive system. When the system process whatever subscription only the firsts four notification are sent by email even thought all the inbox notifications are sent. I checked the mail server and only four smtp connections are sent..... In the development system it is working well, I mean all the emails are sent using the same mail server.... I marked the option Enable session debug info in the EMAIL channel but I see nothing in the los (default.trc).
Is there any log to check what it is happened? Where is the log of session debug info?
Thanks
Antonio

Thanks for you fast replay.
I would like to increase the logging of Notificator (com.sapportals.wcm.service.notificator.wcm) to DEBUG but in NW7 SP13 I do not find that logging locations.
Could you give any hit on it?
thanks
Antonio

Strange behavior of JTable..Help plz

Hi,
Assume i have 5 rows in my JTable. I wrote a function on right click i get a popup window with an option delete row, which deletes the row successfully,
The problem is when i sort the data in JTable. on column click JTable is getting sorted, in which assume 2nd row got replaced with 4th row and vice versa.
Now when i try to delete the 4th row, it is delete the 2nd row data, which was there at the place of 4th row before sorting. In this regard i am trying to print the row number before deleting. It is displaying as 4th, but deleting 2nd row.
Hope i am clear. Please suggest me in solving this strange behavior of JTable sorting problem.
Regards,
Ravi

MyTableModel tablemodel = new MyTableModel(colnames,values);
TableSorter sorter = new TableSorter(tablemodel);
JTable table = new JTable(sorter)
tablemodel.removeRow(row); // last line is the code where i am deleting the row, it's deleting the wrong row.
do i need to remove the last line code and make respective changes in TableSorter.java class.
ore
here itself do i need to do some changes. ?
There is a method that will convert the view row to the model row private Row[] getViewToModel()
my question is how TableSorter.java class comes to know that i am deleting the perticular row.
