How to launch a new JVM from a java class?

I want to update a runing java applicaton. Before updating it, I have to shut down this application and open a new JVM (launch another java class with main method inside another JVM). Then update this application. After updating, restart this application. How to do it?? Thanks. Gary

Hi!
I'm using an applet to upload a library in the ext directory and then opening another applet that uses that library...
If I manually upload the library the second applet works
but if I try to load it at runtime with the first applet the file is saved correctly but the second applet doesn,t work :((
the second applet works only if I close the browser and open it again...:((
I need to reaload the JVM at runtime or maybe opening a new one...
can anyone help me?
please reply me if you found anything similar,
ciao!

How to execute a jsp instruction from a java class?

How to execute a jsp instruction from a java class?
Any help please.
Thank's

I'll detail my problem:
Supposing that I have a jsp file called: start.jsp
In the start.jsp I instanciated an object called global from the class Global ( for example ).
Then, I called a custom taglib:
<ix:mytag/>
In the suitable tld file: the mytag is defined:
<tag>
<tag class>Tag1<.....
The java file Tag1 has method:
doStartTag(){
// here is the problem
global.doSomeFunctions();
Okay, the problem is that the object gobal is not defined in the class Tag1. what to do?
I think that I have to pass the object global as a parameter to the class Tag1. How to do that?
Actually, the problem was to insert the follwoing in the doStartTag method:
doStartTag(){
pageContext.getOut().print("<%= hello world %>");
The output is <%= hello world %> not hello world.
Okay, the new problem is how to pass an object as a parameter to a class called from a tld file.
Any help please.
Thank's too much

How to create a new connection from SAPGUI to Test drive?

Hi,
I have installed Sap Netweaver Test drive on a linux virtual machine (windows host). The installation was successful and I was able to start the instance (application server and the database), yet I don't know how to create a new connection from my SAPGUI client (7.20) to this server. The static IP address of the server is 192.168.1.160.
I entered the following values for my new connection entry
Description: SAP Netweaver
Application server: 192.168.1.160
Instance number: 01
System ID: DB2
SAProuter: /H/192.168.1.160/S/3201/H/
But it does not work. Any idea about the values needed for creating a new entry?
Thanks in advance,

How to display a new view from a nib ?

how to
display a new view from a nib in the main window after clicking on a button.
When I click a the button named for example "goToGokyo", the link to my procedure
runs correctly because I see my NSLog message "goToGokyo button pressed".
My nib, which name is "GokyoViewController" does exist.
I did as follow for the moment but I'm stuck now, my nib :
- (IBAction)goToGokyo:(id)sender
    NSLog(@"goToGokyo button pressed");
//[self stopSound];
if (gokyoViewController == nil)
        GokyoViewController *aGokyoViewController = [[GokyoViewController alloc]
                                                     initWithNibName:@"GokyoViewController" bundle:nil];
        self.gokyoViewController = aGokyoViewController;
        //[aGokyoViewController release];
    [self GokyoView:gokyoViewController animated:YES completion: nil];
Thanks in advance for your advice.
Cheers

I did that now :
- (IBAction)btnLoadMyViewController:(id)sender
    NSViewController *viewController = [[NSViewController alloc] initWithNibName:@"MyView" bundle:nil];
    NSView *view = [viewController view];
    [_myWindowController.window setContentView:view];
    //view addSubview:view];
    //[self.myView addSubview:view];
Using
"_myWindowController.window setContentView:view];"
or
"[self.myView addSubview:view];"
does not an error but does nothing !
Would you help me one more times please ?
Thanks in advance

How do i find new downloads from i tunes in my video app in this os7

How do i find new downloads from i tunes in my video app in this os7. All purchsed items are there, what a
mess???

Leonard,
I used the sample code from StamperUI.cpp as a starting point. I have tried 'LoadBitmap', 'LoadCursor' and 'LoadIcon' and none of these seam to work for me.
As I stated before, I used Visual Studio to create the icons in the resource file, so I would think that they would be recognized by the application.
Thanks,
Gregory

How can I sync new friends from Facebook?

Hi guys,
I have Nokia N9 with the latest firmware version.
I configured my Facebook account and set it to show my friend list in my Contacts.
I can see all my friends from Facebook and they have merged with my contacts list.
But when I add new friends to my Facebook, they won't sync and won't show up on my Contact list.
How can I sync new friends from my Facebook? Is there any way to refresh the list?
Thanks :-)

Only the contents of the most recent photo sync remains on the iPad, so if you want both sets of photos on the iPad you need to include them in the sync - by not including the current iPad photos in the new sync iTunes 'assumes' that you no longer want them on the iPad.

Can you please how to retrive the new netprice from the new validity period

Hi,
When you display a contract using ME33K and you click on a item and view its conditions(shift+F6), there might be 2 validity periods for a given item.
and each period will have different netprice in it.
One will be old date before the PO was created and the other new one which has validity till 31.12.999..We want to fetch the netprice for the new validity date but currently the program is fetching this data from the table EKPO which is having the netprice of the old date only..
Can you please how to retrive the new netprice from the new validity period

Thank you so much.
But I need more help specific to my problem.
Let me describe the same.
Suppose the PO creation date is 04.07.2007
The conditions for an item in a contract for the PO are as follows;
1. Validity from 04.07.2007 validity to 04.07.2007 Netprice = 100.00
2. Validity from 05.07.2007 validity to 31.12.9999 Netprice = 200.00
We need to always fetch the netprice from the validity period which always matches with the PO creatio date. here the value 100.00 should be the correct netpr as the PO creation date matches with the first validity period.
But the program is fetching the netprice 200.000 which belongs to the second validity period. That is beacuse the select statement which fetches the data for contracts collects on the basis of EKKO-kdate and ekko-kdtab.the fields kdate and kdtab retrieves the validity period of the contract which is from 04.07.2007 to 31.072007. This data is then used to retrieve the netpr data from EKPO and it fetched 200.00 as it retrives the netprice of current data in contract validity and h not with respect to PO creation date.
This data is then used to fetch the get the netpr data from EKPO.
<u>what we need is the netprice for that validity period of item(Conditions) that matches with the PO creation date</u>..
Below is the code where I'm selecting the data from ekko and ekpo for the contracts data..Can you please add the code snippet to the below attachesd subroutine to get the required data from KONV and KONP so that we can retrieve the correct Netprice.

How to call a Java class from another java class ??

Hi ..... can somebody plz tell me
How to call a Java Class from another Java Class assuming both in the same Package??
I want to call the entire Java Class (not any specific method only........I want all the functionalities of that class)
Please provide me some slotuions!!
Waiting for some fast replies!!
Regards
Smita Mohanty

Hi Smita,
you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
e.g.
you have developed A.java and B.java, both are in same package.
in implementaion of B.java
class B
            A obj = new A();
             //to access A's methods
             A.method();
            // to access A's variable
            //either
           A.variable= value.
           //or
           A.setvariable() or A.getvariable()
