Sun.applet.appletPanel.run() is invoked twice when applet is loaded.

When I am loading my applet in the browser, sun.applet.appletPanel.run() function is invoked 2 times according to JProfiler.
How can we solve this problem to reduce the number of calls to one???
TIA
Ashish

Anyone having slightest of idea about this problem please reply....

Error 15 at "Run VI" Invoke Node When Building a LabVIEW Executable

I am trying to run a vi by using the "run VI" method of the invoke node. The source code works perfect. However, I cannot run the vi when I use the executable version. Specifically, I get the Error code 15 at the "error out" output of the invoke node while using the executable version. Why is this occuring?
Thanks

Hello ameng,
This behavior is typically the result of trying to call VI that has had its front panel removed. The KnowledgeBase linked below has more information on this issue.

NullPointerException at sun.applet.AppletPanel.findAppletJDKLevel

Hi,
we have a online HTML page containing an <applet> and different <iframe> definitions. By clicking a HTML link or calling Applet.getAppletContext().showDocument(), other HTML pages containing other applets are loaded into the referenced frame. All applets have identical archive and codebase attributes, allowing them to communicate with each other.
This works actually very well. The problem is that sometimes newly loaded applets do not start, and a red cross appears in the inner frame. In all cases, the following exception appears in the java console (which does not happen if everything works fine):
java.lang.NullPointerException
at sun.applet.AppletPanel.findAppletJDKLevel(Unknown Source)
at sun.applet.AppletPanel.createApplet(Unknown Source)
at sun.plugin.AppletViewer.createApplet(Unknown Source)
at sun.applet.AppletPanel.runLoader(Unknown Source)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
We experienced this on customer clients using
- Windows XP or Vista
- SUN Java 1.6 (e.g. Java 1.6.0_02), Java 1.5 worked so far
- Firefox2, IE6, IE7
Any ideas?
We use the JarIndex mechanism to enable dynamical class loading, could that cause problems?

After installing JRE1.6.0_02, the problem occured now as well, but didn't occur under the previously JRE1.5.0_07 version.
For me, it seems to be some classloader related timing problem and occurs even in the following scenario:
I have a main frame m, containing an inner frame a with applet A and an empty inner frame b.
1. at startup, A gets loaded into a. A starts well.
2. A loads a second Applet B via <applet> into b. B starts well.
3. Click HTML button within m loads a third Applet C via <applet> into b. Using Java 1.6, B does sometimes not start (see first post)
4. Click HTML button within m loads B via <applet> into b. This works.
5. Click HTML button within m loads C via <applet> into b. This works sometimes, sometimes not.
So, the class needed at that moment (whatever that is) is actually available but cannot be loaded properly at first start for some reason.
As said before, codebase and archive tags are exactly the same. Javascript is not used at all. I couldn't set up a test environment to simulate this effect, so I'm sorry that I couldn't supply any code example.
Does anyone could give me a hint please?

Invoke Method: Run VI produces error when run as an application

Hello,
I have upgraded from LabView 7.0 to 2009. One test program uses Run VI Invoke Method to start the main UI. On LabView 7.0 it works OK , when build as an application, but with LabView 2009 it gives error 1003: Invoke Node xxx.vi <APPEND> VI Path: xxx. (I have checked that the path to "Open VI Reference" is correct.)
When run on LabView 2009 development environment (.vi) - no problem. I used the "Convert built script.." tool to convert to LabView 2009 built specifications. I have tried numerous different variations building application with LabView 2009 (including main UI files, different setups, etc.), but no luck. If someone has any ideas...
-timo

Maybe it helps you for debugging:
I checked the property for the broken arrow. You need a property node and go Select Class 'Vi Server'->'VI' (skip this in your Application but navigate to the VI via the server and feed it to the node). Then it is Execution->State.
I need to draw some code to do it for me as well, once I'm done I'll post it here.

Components and applet not loading when running the application using JVM1.3

I have my UI written in JavaScript.When I click a button,it opens a window showing the different components(images) and an applet containing a tree structure.The applet code is written in java
This is working fine and the applet is loading properly when I use JVM1.4. But there is a problem when I use JVM1.3.1_09.The images appear broken and the applet doesnot load.(When I click on one of the broken images,the images appear correctly but the applet still doesn't load)
Can anyone tell me what could be the reason behind this behavior??

ClassFormatError when attempting to load an applet from within a JSP

Greetings everyone.
I have a problem that i seem unable to solve.
I've created a web application. I'm using Java 1.4.2_05 and Tomcat. Right now i'm trying to load an applet from a JSP and i'm getting an error that, try as i might, i can't understand why it happens.
Here is some detailed info:
The applet's code:
package smpb.myapp.controllers;
import java.applet.Applet;
import java.awt.Graphics;
public class GUIApplet extends Applet
     public void init()
     public void stop()

              g.drawString("Hey hey hey",20,20);
           g.drawString("Hellooo World",20,40);
The JSP's code:
<%@ page language="java"
               import="java.util.*"
               session="true" %>
<%

I've checked and rechecked to see if all the permissions to access the jar file were accurate, i checked to see if Tomcat had it's MIME settings correctly configured so that there was no chance that the files were being corrupted during the load (as that is a usual cause for the problem, or so i've gathered) but to no avail. I've searched the web, including these forums, and found similar problems but no conclusive solution. I can't seem to figure out, at all, what could possibly be wrong. Does anyone have any ideas? I've tried to be as thorough as i could from the start, so, any help would be deeply appreciated.

Hi mshah101,
This can happen if the applet is compiled using an higher version of java and the browser is pointing to an older version (even if minor version number is higher)

Sun.applet.AppletViewer vs. appletviewer

What's the difference between sun.applet.AppletViewer and just plain appletviewer. I recently had a problem with sun.applet.AppletViewer and I just wondered what the difference between the two is. I've looked around on the forum and conducted a search on the java.sun.com website. I can't really find any documentation on sun.applet.AppletViewer.
Thanks,
Lisa

I presume that they are the same? i.e. sun.applet.AppletViewer is the class that is used when you run appletviewer
How come you're using sun.applet.AppletViewer anyway if there's no docs for it? :)

Limiting script to run once or twice

I have this script which I'm trying to collect snmp stack based on the %SNMP-3-INPUT_QFULL_ERR. But my concerns is that when these error starts they run for about 2 hours and I get thousands of syslog entries for this error. I want to be able to limit this script and may run once or twice regarldess of how many error I get. Can someone assist me in tweaking this?
Thanks.
event manager session cli username "username"
event manager applet SNMP_STACK
event syslog pattern "%SNMP-3-INPUT_QFULL_ERR" occurs 32
action 1.0 cli command "enable"
action 2.1 cli command "show clock | append bootflash:SNMP_STACK.TXT"
action 2.2 cli command "show proc cpu sort | append bootflash:SNMP_STACK.TXT"
action 3.1 cli command "show stacks 560 | append bootflash:SNMP_STACK.TXT"
action 3.2 cli command "show stacks 560 | append bootflash:SNMP_STACK.TXT"
action 3.3 cli command "show stacks 560 | append bootflash:SNMP_STACK.TXT"
action 3.4 cli command "show stacks 560 | append bootflash:SNMP_STACK.TXT"
action 3.5 cli command "show stacks 560 | append bootflash:SNMP_STACK.TXT"
action 3.6 cli command "show stacks 560 | append bootflash:SNMP_STACK.TXT"
action 3.7 cli command "show stacks 560 | append bootflash:SNMP_STACK.TXT"
action 3.8 cli command "show stacks 560 | append bootflash:SNMP_STACK.TXT"
action 3.9 cli command "show stacks 560 | append bootflash:SNMP_STACK.TXT"

One way to do this would be to have this applet install a second, timer-based applet then sets the event detector type of itself to "none". The second applet would countdown the number of seconds that correspond to your time window, then reconfigures the event detector on the first applet to be your syslog event. For example:
event manager environment q "
action 4.0 cli command "config t"
action 4.1 cli command "event manager applet stack-countdown
action 4.2 cli command "event timer countdown time 7200"
action 4.3 cli command "action 1.0 cli command enable"
action 4.4 cli command "action 2.0 cli command $q config t$q"
action 4.4 cli command "action 3.0 cli command $q event manager applet SNMP_STACK$q"
action 4.5 cli command "action 4.0 cli command $q event syslog pattern %SNMP-3-INPUT_QFULL_ERR$q"
action 4.6 cli command "no event manager applet stack-countdown"
action 4.7 cli command "event manager applet SNMP_STACK"
action 4.8 cli command "event none"
action 4.9 cli command "end"

Database call fired twice when using actionListener in dataTable

Hi all,
I have a question regarding the request bean lifecylce in the current use case (using Sun JSF 1.2)
I have a managed bean in request scope that contains an ArrayList which is used as the data provider in a dataTable on a faces page.
The bean contains an init() method to populate the ArrayList using a database call.
The dataTable also contains a column with a commandLink that calls a method via actionListener inside the managed bean to delete the current row.
When I click the link the action gets called and deletes the row from the database. I also reload the data from the database and assign it to my ArrayList.
However, the init Method is also called before the action is executed. So the database call is fired twice when hitting the link:
- First time in the init() method of the bean
- Second time in the actionListener method when reloading the data
I can not remove the call from the actionListener, because the data has not deleted yet.
Question:*
How can I make sure the database call is fired once only? (and also making sure the ArrayList is populated appropriate)
Maybe I am doing something wrong here? Thanks in advance for any help.
Maik
This is the request scope bean:
public class UserBean implements Serializable {
    private List all;
    private Long userId = null;
    @PostConstruct
    public void init() {
        if(all == null) {
            new ArrayList();
            loadUserList();
     * Constructor
    public UserBean() {
        super();
     * @return the userId
    public Long getUserId() {
        return userId;
     * @param userId
     *            the userId to set
    public void setUserId(Long userId) {
        this.userId = userId;
     * @param all
     *            the all to set
    public void setAll(List all) {
        this.all = all;
    public List getAll() throws GeneralModelException {
        return all;
    public void loadUserList() {
        EntityManager em = Contexts.getEntityManager();
        Query q = em.createNamedQuery("user.findAll");
        all = q.getResultList();
    public void deleteAction(ActionEvent ae) {
        EntityManager em = Contexts.getEntityManager();
        Query q = em.createNamedQuery("user.byId");
        q.setParameter("id", userId);
        try {
            User user = (User) q.getSingleResult();
            if (user != null) {
                em.remove(user);
                loadUserList();
        } catch (NoResultException e) {
            // TODO
}

No, I do not call the init() method.
Basically the init() is called before the deleteAction() so the ArrayList still contains the old value, unless a second database call is triggered after the entity has been deleted.
Maybe I am missing something here...

Client cert password asked twice when requested in ie 6.X, 7

Hi all,
I have a ssl web server instance (Sun Java Web Server 6.1SP8) configured to ask for a client cert when a certain resource is requested. Accepted client certs are contained in a client smart card, password protected. When using internet explorer as browser, the password window to access the certificate is asked twice when requesting for the protected resource.
When using firefox the password is only asked once.
To configure the web server I've modified obj.conf file adding
<Client uri="/myuri/*">
PathCheck fn="get-client-cert" dorequest="1" require="0"
</Client>and magnus.conf adding
KeepAliveTimeout 0Has this something to do with the web server or is an internet explorer problem?
Thanks in advance.

Have you added any redirects in your obj.conf ?
Do you see any thing in error logs when you run server in <log-level>finest</log-level> mode and compare the difference between IE and firefox.
Some reference about get-client-cert :
http://docs.sun.com/app/docs/doc/820-2203/abujm?l=en&a=view
+"The get-client-cert function gets the authenticated client certificate from the SSL3 session. If the certificate is present or obtained from the SSL3 session, the function returns REQ_NOACTION and allows the request to proceed. Otherwise, it returns REQ_ABORTED and sets the protocol status to 403 forbidden, causing the request to fail."+
In Web Server 7.0 try and add the following in server.xml also and see if it helps :
In <ssl> element add
<client-auth>required</client-auth>or
<client-auth>optional</client-auth>Note that this setting will work for all URIs not just /myuri

No return in JS when accessing an applet in loading process

When I try to access a property or a method of an applet which is
not completely loaded by the plug-in, my javascript instruction
never returns. Not even an exception or a null. The CPU is 100% busy
with the netscape.exe for ever. When I close the browser, I get a
Dr. Watson.
Context :
Netscape 6.2, plug-in 1.3.1 or
Netscape 7.0, plug-in 1.4.0
My purpose is to call the applet just after everything is put in place:
the applet is loaded, ready is work and laid out on screen. So I do
the call on the BODY onload event. It's fine with NN4.7 or IE5.5 and
their internal JVM because when the event fires, the applet is ready.
The problem is with the plug-in. I know that the onload event fires
as soon as the HTML is ready, independently from the applet which is
taken in charge by the plug-in. The availability of the applet takes
some time because it comes from a signed Jar from a protected area of
the web server. So you have to walk through two additional steps:
authentify yourself with the server (first popup) and grant session
privileges to the applet code (second popup). During this time, onload
has been executed. I know I have to check if the applet is up and if
not try again later with a setTimeout().
But how to check the readiness of the applet? When I try to read
whatever from it too soon, the code will never return !
To demonstrate the no-return, just put an alert and wait for the applet
to be loaded and fully active. Then you can have a return from it.
Don't forget: because of the user prompts (authentication and grant),
I can't determine a time to delay the check.
The code:<HTML>
<HEAD>
<SCRIPT>
function initApplet() {
// If you uncomment the following alert() and wait
// for the applet to be fully loaded and running, it will be OK.
// If you don't, "document.applets[0].isActive" will never return.
// alert("wait")
if (document.applets.length != 0
&& document.applets[0].isActive
&& document.applets[0].isActive()) updateApplet()
else setTimeout("initApplet()",1000)
function updateApplet() {
alert("call the applet")
</SCRIPT>
</HEAD>
<BODY onload="initApplet()">
<APPLET code="test.class" width="760" height="220" name="theApplet"
archive="theSignedJar.jar" MAYSCRIPT>
</APPLET>
</BODY>
</HTML>

I am having a very similar problem in Netscape 6.2 or later. (It never occurs in Internet Explorer) The applet can contain a few or many (in the 1000's) of applet parameters.
I am following the same pattern to determine when the applet is loaded (by referencing a flag that is set to true through the applet), which seems pretty standard. The applet is loaded, and the flag is set, but when I begin to process the parameters, the first parameter that is examined is returned as null, even though it is included as an applet parameter in the HTML file that is generated. FYI the first parameter processed is the last one included in the source file. The worst part about this error is that the error seems random. Sometimes it works; other times it doesn't.
Has anybody ever seen documentation as to how the parameters are loaded into memory, i.e. in what order? Does anybody know the algorithm used by the runtime system to find a parameter when a call to getParameter() is made?
Any insight would be greatly appreciated!

LabVIEW Application throws Error in Run VI Invoke node

Hi All,
We are facing an issue with an application developed from LabVIEW 2010SP1.
Application Description:
In our application, there is a top level VI which tries to run VIs dynamically[using Run VI invoke node] from a particular folder. This folder is like a plugin - not part of Exe. This implies when the top level VI is launched, the plugin VIs under particular folder will not be in memory. When we try to run a VI dynamically from the top level VI, the VI execution works perfectly in LabVIEW development mode.
Problem Faced:
When we created an EXE, it worked well in my PC [LabVIEW is installed]. We created an installer and tested in few other PCs.
[Non LabVIEW PCs – Win XP and 7]. In few PCs it throws the following error, when the plugin VI is run dynamically.
Error 1003 occurred at Invoke Node
Possible reason(s):
LabVIEW: The VI is not executable. Most likely the VI is broken or one of its subVIs cannot be located. Select File>>Open to open the VI and then verify that you are able to run it.
Method Name: Run VI
We tried the following possible ways to find the reason for the issue:
1. Installed LabVIEW - Issue got fixed.
2. Installed .net 2.0 without installing LabVIEW - Issue got fixed.
3. But in one of the Windows 7 [Non - LabVIEW PC] in which .net was already installed, we faced the same error.
Only after installing LabVIEW the error got fixed.
4. When .net 2.0 is uninstalled the EXE itself is broken.
We are not sure what is the Exact reason fo the issue. Anyone faced these kind of issues? Please share the solution. Thanks in advance.
Note:
1. The VIs which are dynamically called is a plugin and not a part of EXE.
2. These plugin VIs have no dependencies from vi library and is completely isolated.
3. We are not using any .net related objects in any of the VIs.
4. The plugin VIs use Call library function node in which a C DLL developed from Microsoft Visual Studio 2010 is used.
Thanks,

Error 1003: This clearly indicates that the 'Dynamic VI' is broken and now you should check for the various reasons, why the 'Dynamic VI' is broken.
Also path of 'Dynamic VI' is not a problem.
One thing that you may try is:
-> First open just the 'Dynamic VI' in a new LabVIEW project and check for the 'Dependencies'.
-> Now if any of the item in 'Dependencies', other than what is listed in vi.lib (lets call it 'Dependency.VI'), is also a part of your 'Main Exe', then its a problem. Because when you will execute the 'Main Exe', say in a new computer other than your development computer, it will load all its dependencies including 'Dependency.VI' (and the path will be within the 'Main Exe', but when it will try to (dynamically) load the 'Dynamic VI', this VI will also try to load the same 'Dependency.VI' but from different path and that will cause a conflict. I had experienced this.
-> If thats the issue, you may want to rename (add suffix/prefix) to all dependencies of your 'Dynamic VI' which is common to the 'Main Exe'.
Hope this solves your issue.
I am not allergic to Kudos, in fact I love Kudos.
Make your LabVIEW experience more CONVENIENT.

HT1379 My macbook pro 2013 is running to slow even when I am using the keyboard, it running with a delay. I upgraded the memories to 8gb but still slow what can i do to fix it.

Good morning I am confronting serious problems with my Macbook pro 2013, that is runing to slow, even when I am writing this email is running with some kind of delay. I upgraded the memories to 8gb but still running slow . Please let me know what I can do to solve the problem. Thanks in advance. Fernando

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a couple of minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter
exec bash
in the window and press return. You should then get a new line ending in a dollar sign.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
8. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If it happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Does "Run VI" invoke node work on strict references to REENTRANT VIs?

I am using LV 6.02 on Windows 2000.
I am trying to use the "Run VI" invoke node method with a reference to a Reentrant VI, with no success. (It works when VI is not reentrant. Perhaps there is a reason this cannot work. But if not, I wonder if there is a workaround, or if LabVIEW 6.1 has a fix?
Hopefully the picture of the block diagram I included is sufficient...but I also included the actual code just in case.
Thanks!
Steve

Hi, Labviewguru,
Thanks for taking the time to look at my admittedly messy (flawed) block diagram. I will try to state my ultimate goal:
You may be familiar with Levinberg-Marquardt nonlinear curve fit in Labview, which is about 5 VIs in a LLB file. In order to change the type of curve fitting, one has to either modify a formula node in the lowest subVI (Target Func and Deriv), or place a different subVI in there. That's fine until I want to have many different sorts of algorithms.
What I was thinking of doing is instead passing Target Func and Deriv a reference to the VI which would perform the calculations. This would allow me to use the same fitting code to fit different types of data with substantially different methods--without modifyin
g the low-level fitting code at all.
I'm not sure this is going to make any sense to you, but thanks again for your help.
In regards to your answer above, let me clarify somewhat. I had the call by reference node in there to prove that the reference to the VI was "good" and worked fine...this same reference was passed to the invoke node, which didn't have any apparent effect.
Also, I don't think the path to the VI I am opening the reference to is redundant. It is required to tell the "Open VI reference" which VI to load.
I agree that using references to pass values around is not generally a good idea: I was using that method for my supposed versatility in the future.
Thanks,
Steve
