How can i catch the jsp checking event ?

As we know, there are three parameters which is about checking in the weblogic.xml, pageCheckSeconds,*servlet-reload-check-secs*,*resource-reload-check-secs*, but how can i catch the checking event when the webapp is active.
The fellowing is my simple test, i deployed a webapp on a weblogic server instance, and it was actived. I wrote a simple bash shell to try to catch the event, but fail. i througnt it may be dependent on the webapp's stage mode. but i change the mode, and try again, it was fail too.

WebLogic 9.2 MP4、Redhat Linux AS 4 Update 8 x86.

I tested on WLS 11g ps2(10.3.3) which is running in Development Mode also, but it was the same as WLS 9.2 MP4.
During the weblogic server running, it don't check the application resources , but it will check the $Domain_Home/autodeploy directory every three seconds in Development Mode , the following is the result.

How can I catch the exception type c = type i?

How can I catch the exception and display the error message when I assign the u2018ABC123u2019 value to an int data type.
Code is as follow.
REPORT zfsl_sum_functions.
DATA: cin(50),
      cout(50),
      iin TYPE i,
      iout TYPE i,
      etext TYPE string.
cin = '123ABC'.     " how can i catch this
iout = cin.
WRITE: iout.

The CATCH-ENDCATCH statement is obsolete as of release was620. You should use TRY. CATCH. ENDCATCH.
The exception that will be raise is CX_SY_CONVERSION_NO_NUMBER, so you have to catch that exception or a super class of this exception class.
REPORT zfsl_sum_functions.
DATA: cin(50),
cout(50),
iin TYPE i,
iout TYPE i,
etext TYPE string.

How can I Catch the program to prevent exit all?

Hi,
I am actually implementing a Ptolemy GUI for my subject. And I am now facing a very serious problem. I build an application to call the Ptolemy application to probe up a plotting graph program. Every time after I call the run Simulation() the program call the plotting from Ptolemy, but when I press close from the plotting, everything close including all applications that are not expected to close.
The problem I think is located here:
PtolemyApplication exec_model = new PtolemyApplication(argument);
So I would like to know how can I catch its exit to avoid closing everything.
Can anyone give me suggestion please?
below are the method I call:
public void runSimulation()
try{
File file = new File("default.xml");
DataOutputStream out =
new DataOutputStream(new FileOutputStream(file));
SimGraphWriter writer = new SimGraphWriter();
boolean checkAllConnected;
checkAllConnected = writer.write(graphpane.getGraphModel(),
graphpane.getGraphView(),currDirector, out);
if(checkAllConnected){
("//d/Ptolemyii/ptII0.4/ptII0.4beta/bin/ptolemy.bat ./default.xml");
               String argument[] = {"default.xml"};
               try {
                    PtolemyApplication exec_model =
new PtolemyApplication(argument);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                    this.dispose();
               catch(Exception ex) {
                    System.out.println(ex);
                    ex.printStackTrace();
catch(Exception ex){
          System.out.println(ex);
ex.printStackTrace();
}

Thread is an object that u create just like String /or whatever eg;-
Thread firstThread, secondThread, thirdThread;
once they're declared u can stop, start + run them individually with boolean values (true /false) and therefore control what u want to do when.
Play with the code examples + mess around with it - it's not absolute beginner stuff - but it isn't that tough either

How do I catch the button click event from toolbar for my JSP?

I am using JDev 3.2 and BC4J for my JSP. I am using data web bean methods to create my JSPs. I need to implement a
master-detail relation in my JSP. Currently I put my master browser as the top frame of JSTabContainer bean and put my
6 detailed tables into 6 tabs. I found that when I click the next or previous button of toolbar of master frame, the detail tab
does not display the corresponding detail data properly. I think the reason is that I did not refresh the tab content when
the user change the current record of master table. Now my question is that how do I catch those events so that I can
refresh the content of my detail table? Or whatever suggestion can make this work.
Thanks,
Lisa

You posted here with Firefox 17.0.1.
Try running a Norton Live Update so Norton can update their Firefox add-on and get that Toolbar working again.
That said, Norton doesn't do anything about Malware. You need a Malware application to locate and remove Malware.

How can i catch the gotfocus and lostfocus events

Hi Dear;
i tried to catch the gotfocus and lostfocus events, but i can't.
in the same code i can catch the onclick events.
is there any special code for the gotfocus and lostfocus events?
regards;

Danny;
Whenever I have an issue such as this I fire up the event logger and it will show you exactly which events you can put your hooks into. If you are not using it you should really check it out. Will save you tons of time.

How can I make the jsp pages not displayed by using the navigation class?

I'm right now implementing a function on my program GUI . It's like whenever I click "STOP THE SERVER" button on the main page, I need those jsp pages relates to the server running to be not displayed, even by directly type in the URL(that's just stay in the main page), How can I do that? I heard that a navigation class might do it, but I'm not sure how. It might be great if some experts could help me!! Thanx a million !!

I have a load of songs in a checklist, how can I get the ones checked to play?

I have a load of songs that I have check boxes next to. I want to get the ones that the user checks to play one after the other like a playlist?
How can I do this? I'm new to macros etc.
Thank you!

Check boxes won't work. You need an actual player that supports playlists.
Have a look at Pickle Player.

Urgent: How can I catch the exception when application exit by accident

Can anyone give me advice and idea?
I want to catch the exception when application goes down by accident for example: Power off, turn off the machine without closing the appliction properly.
Because I want to notify the server and remove it from register.
How can I do this????
Please help,
Thanks very mich,
Peter

Shrubz,
I tested my application as follows:
1. start rmiregistry
2. start rmi server
3. start two clients
I printed out the client's object information as below:
first clinet:
RemoteObserver is com.ss8.qos.qcsm.policy.policyui.PanelMain_Stub[RemoteStub [ref: [endpoint:[192.168.70.237:4706](remote),objID:[-73a6662b:e75af455a5:-8000, 0]]]]
second client:
RemoteObserver is com.ss8.qos.qcsm.policy.policyui.PanelMain_Stub[RemoteStub [ref: [endpoint:[192.168.70.237:4711](remote),objID:[-73a6665a:e75af48703:-8000, 0]]]]
Now I stop the second client by clicking ^C (ctrl c)
I noticed that this client has not been removed from the server register (Vector).
next, I am working on first client for example add one record. After server received this record, it will update all clients who have already registered with server. Because now in the server register there are two clinets (first and second), so it will try to update two clients. The exception will be thrown when server tries to update second client which has already been stoped. I used printStackTrace() to print out the message as follow:

How can I catch the exception which is from the server validation of item.

I create a messageTextInput and then set the maximumLength is 10.
At the same time, I create a submitButton and set the attribute serverUnvalidated is FALSE and unvalidated is TRUE.
Running the page, after I input the 10 Japanese word(20 bytes), the page will show a error message.
it's meaning that the input value is too long.
My request is I don't need to show the error in the page. How can I deal with it.
Thanks.

Check by increasing maximum length (more than 20) if possible to you.

How can I eliminate the spell check in Firefox?

I do not want to have the spell check active when I use Firefox, how can I eliminate it?

You want to disable the spell check in forms (e.g., data entry controls like the one I'm typing in right now)? You can do this using the about:config preferences editor.
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''spell''' and pause while the list is filtered
(3) Double-click '''layout.spellcheckDefault''' and change it to 0 (''zero'') and click OK.
You're done, you can close that tab.
The change should take effect the next time you reload the form.

How can I reduce the number of event cases in the main VI?

I would like to reduce the number of event case of the event structure in my main VI. E.g. I would like to have pop up window with a table when the user double click a table row. Nothing more simple than this: add a case to the event structure trigger by double clicking the table, read the table row ... But in my main VI I would have lots of them and the event structure gets crowded with minor tasks. One solution is using XControls. But is there any other recomended way to handle selected events separatly from the event structure in the main VI?
to clarify: I don't want to distribute the whole event structure. (In this case the code would not be maintainable) But I would like to handle certain context specific events in a differnt place. If I have them all in the main VI the drop down list of the events in the event structure exceeds the windows size and the program becomes difficult to maintain because one looses the overview.

"Strictly forbidden" is not true. But highly not recommended. The reason is simple:
1. Code can react unpredictable. Dennis already stated some things about that in your linked thread.
2. Code is not readable and therefore not maintainable. Each event source should have only one event structure for its events. Since the UI is a single source, events from there should be captured in a single event structure. It is recommended to use this event structure as producer in a producer/consumer design pattern in order not to block the events.
3. You will most propably need timeouts in your event structure which completly negates the advantage of event driven programming. Either use event driven programming or stay at polling. Do not mix (most of all because of maintenance).
Regarding your "advantages" you listed:
- Clustering reduces readability in therefore should never be done. Additionally, it requires timeout cases in most places which is not recommended.
- If you have such many events and interactions in your "sequence", it is a clear indication that you chose the wrong architecture for your application.
Please see attached example. Since i am not used to program with more than one event structure (except if i have different dedicated event sources), the example is "constructed" and therefore may lack of "realism". Nevertheless, it shows some issues which might occur:
- Blocking calls within the events lead to the fact that the UI is not responsive for the event time (FuncA). Nevertheless, interaction is still enqueued and if the blocking call is over, all those interaction are executed. In the example, please press FuncA and then press FuncC immediatly. You will see that nothing happens and after the 5s blocking call, the FuncC dialog appears. You also can switch tabs, but the visual display will update only after the 5s blocking call.
- In order to keep the UI responsive, FuncB is configured not to block the UI. But this is no solution: Press FuncB (on page 2) and the change to page 1 and press FuncA. Additionally, press FuncC. What happens? Just to mess things up, press Stop as well......do this combination several times. It is possible that only the lower loop is finished and the VI is still running even if Stop has been pressed.
Please note everyone that the attached example shoudl strictly be seen as "NEVER DO IT LIKE THIS". This is a negative example and shows the approach which is not recommended by any means!

How can I avoid the plugin check page?

Every time I open Firefox now, I get a second tab taking me to the plugin checker page. I updated all the vulnerable ones, and I just don't want to see the thing every time I open firefox! Can I disable this annoying feature?

I uninstalled Viewpoint Media Player (and the AOL IM client "AIM", since apparently that's what forced Viewpoint Media Player on to my system.) Viewpoint Media Player is responsible for the plugin called "MetaStream 3 Plugin r4", and I believe this plugin is triggering Firefox to open the plugincheck page. It is not enough to disable the plugin, it must be uninstalled. For me, after uninstalling Viewpoint Media Player, the "plugincheck always opening" problem then went away.
I see, however, that you do not have this plugin ("MetaStream") in your plugins list. So it may be that there is some other plugin of yours that is causing this tab to pop up. Go to Tools->Addons->Plugins(tab), and look in the list for any plugins with a red warning icon. If there are any, this is probably the plugin causing the problem.

How can i catch the jsp checking event ?
