How to call an applet on click of a button in core java?

On this, I suggest that if we can call commond prompt on background and then pass the path of the class file of another applet we can open another applet on clicking on the button what u says ? if any suggestions or code u can give it is our pleasure to know that.

If you are asking if you can execute an external process (application/applet) from another application/applet - the answer is yes and no.
Yes. If you have the security settings/policy to do so.
No. This may require a security policy to be allowed - as an applet.

How to call a method by clicking on a button

hi, I have made a jsp page where I define a method toto.
what the html source code for a button wich when you click it will process this method ?
thanx

There is no HTML source (or Javascript source either) that can directly call your toto JSP method. Think of it like this. You want to send a request from the browser to tell the JSP page to run method toto. For example, if the JSP page is named myPage.jsp, then the request could be as simple as myPage.jsp?action=runtoto (or http://yourwebserver/your/page/path/myPage.jsp?action=runtoto as an absolute URL). The JSP would then need to look for the action parameter as it is sent from the browser. If the action parameter equals "runtoto" then you could call the run tot method. Example:
<%String action = request.getParameter("action");
if(action.equalsIgnoreCase("runtoto"))
toto();%>
This could be coded in myPage.jsp and would run the toto method whenever the browser requested it via the action parameter. The HTML for the request could be coded as a button, a hyperlink, or anything that would generate a new page request.
<form action="myPage.jsp" method="GET">
<input name="action" type="button" value="runtoto"> Click to run the toto method.
</form>
Of course you have to consider the other parameters that will be submitted with the form. This may present some design issues/questions.

How to call a Applet from a servlet and vice versa...?

Hi all
Can anyone help me how to call a applet from a servlet and vice versa. When the applet is called it should contact the database (oracle8i) and get the data. When i submit the applet form the data in the applet should be saved in the database.
Thanks in advance
Kamalakannan

Sweep is correct about requestDispatcher being another approach for inter-servlet delegation; the only issue that i recall with this approach is that it defaults the method of the destination servlet to the one it was called from...for example, calling servlet2 from within servlet1.post() resulted in the dispatcher attempting to utilize servlet2.post() - i believe that i searched for a parameterize solution to no avail :( (ended up handling the request by placing a "fake" doPost() in servlet2 that simply called servlet2.doGet())
however, if your application is functioning correctly on your pc/webserver then the problem may be external to servlet communication (e.g. client webserver's ports not configured or blocked, missing runtime classes, etc.)
my suggestion would be to set aside the programmatic concerns for the moment - what is the response if you open a browser on a client's machine and access the URL in question (i.e. http://clientserver:port/stefanoServlet)? If it will not respond to access in this manner then it certainly won't when your application calls for it.
It's possible that there is a coding error but, given the info supplied, i'd start examining the environment, first. Let us know if you have any luck with the test i recommended or not (please provide abundant detail). Or, if you've found the solution then you may want to post back with a quick blub so the next person knows how to escape the trap.

How to call an applet from a first applet

Hi,
I need to call an applet from a first applet, but I want that the called applet doesn't execute in the same AppletContext than the first one, is it possible?
If it is, what is the solution?
Thanks

Yes, it is possible. One way would be to use static variables.
class A1 extends Applet
   public static A2 TheOther;
   public A1()
      A2.TheOther = this;
   public void callA2()
      TheOther.doSomething();
class A2 extends Applet
   public static A1 TheOther;
   public A2()
      A1.TheOther = this;
   public void doSomething()

How to call a method on click of selectOneChoice dropdown box

Hi,
I am using selectOnceChoice whose list is coming from an arrayList.
On the load of my page, I am populating the arrayList and it is getting visible in the selectOneChoice dropdown.
But I have a scenario where I need to populate the arrayList(List Items) for selectOnceChoice on click of selectOnceChoice box. Not at the time of page load.
I tried to do that with the help of clientListener and ServerListener but it seems that it is ServerListener is not the child attribute of selectOnceChoice.
Can anyone please help me out to perform or call a method on click of selectOnceChoice box.
Thanks,
Vicky

Could someone please explain to me the main difference between adapters and listeners? WindowListener is an interface, if you use it then you have to implement all its methos whether you use then or not while WindowAdapter is a class which implements WindowListener and provides empty implementations of all the methods in the listener, so basically by using windowAdapter you are avoiding
the implementation of methods which you don't required.

How to call initial screen from Sm30 screen back button

Hi All,
I have written a program to call SM30 transaction using BDC method.The values entered on initial screen of report are being passed on to SM30 screen through BDC . As per selection criteria inserted on screen only those particular entries are being displayed on SM30 table maintenace screen.
But when I click on BACK button on table maintenace screen of SM30 it takes me to first screen of SM30 ransaction instead of report's first screen.
What do I have to do to move on to first screen of report when BACK button clicked .
Thanks
Saurabh

Creata table maintenance generator for your table. You need not have to do a BDC to SM30 to maintain the table. You can use the FM "VIEW_MAINTENANCE_CALL" by passing the table name. This will also take in the criteria to filter the record in the table display. Now if you press back button from here it will take you back to your report screen.

JDev 10.1.3 ADF: How to fire an event when clicking a Radio Button

I have a <af:table> component with the following code for my radio button
<af:tableSelectOne text="Select and"
binding="#{backing_viewFees.tableSelectOne1}"
id="tableSelectOne1"
attributeChangeListener="#{backing_viewFees.tableSelectOne1_attributeChangeListener}"
autoSubmit="false">
When I click the radio button it does not fire up my event in my backing bean?

Thank you for the suggestion...it does work and fires the event, but it is still not selecting the current record when I try to perform an Update or Delete.
I had to modify your code a bit in order for it work in JDev 10...used the JUCtrlValueBindingRef instead of the FacesCtrlHierNodeBinding.
Here is what my af:table tag looks like:
<af:table value="#{bindings.FeesView1.collectionModel}"
var="row" rows="#{bindings.Fees001View1.rangeSize}"
first="#{bindings.FeesView1.rangeStart}"
emptyText="#{bindings.FeesView1.viewable ? \'No rows yet.\' : \'Access Denied.\'}"
selectionListener="#{backing_viewFees.tableSelectOne1_attributeChangeListener}"
binding="#{backing_viewFees.table1}" id="table1">
If I put back my 2 original attributes, then my Delete and Updates work.
selectionState="#{bindings.FeesView1.collectionModel.selectedRow}"
selectionListener="#{bindings.FeesView1.collectionModel.makeCurrent}"
Here is my code in the backing bean:
public void tableSelectOne1_attributeChangeListener(SelectionEvent selectionEvent) {
JUCtrlValueBindingRef binding = (JUCtrlValueBindingRef)this.getTable1().getSelectedRowData();
if (binding != null) {
Row currentRow = binding.getRow();
if (currentRow != null) {
System.out.println(currentRow.getAttribute("CurrentRecordInd")); // this does print my selected value!!!!
}

How to call a method on clicking Search Button in a jspx page.

Hi All,
I made a simple search page with two search criteria. Also i used LOV's for selecting the values to these view criteria's.
Now i need to validate the criteria's being passed before page renders. Based on the validation i would like to change my base query of the page.
Is this is possible to have two different query for the same page.
If yes then please guide me to achieve this !!!
Regards
Siva

Hi Arun ,
Thanks for the reply,
This is the actual scenario,
I need to allow user to querying using a particular atrribute say A1 but applying A1 directly as a criteria on my base query along with other criteria will not fetch any details.
Instead
I need to fire the same query with A1 alone initially and on top of the fetched results i need to apply the other criteria
OR
I need to get the A1 from user and fetch some other attribute let's say A2 corresponding to A1 and this A2 has to applied as the new attribute along with the other attributes.
Can this be achieved.
Regards
Siva

How to open a form on click of a button in infopath

I have created an infopath form on a list. I need to create a button on the pape on click of which the last item created by the user should open. I mean the edit form of that list item should open.
How can we do this ?
Thanks for your response in adv.
Regards,
prajK

Hi,
Per my understanding, you might want to add a button on a page, when clicking it, the last form which is created by the current user will open.
As it might require to query the last form created by current user, custom code would be required.
A solution is that, you can query the URL of the last form created by the current user using JavaScript Client Object Model, generate a button with the URL retrieved
using JavaScript. Then when user open this page, the button will be created dynamically, user clicks it, the last form created by this user will open.

How to Handled Shift +Tab(Focus) click in radion button?

Hi,
I am using Jdeveloper 11.1.2.0.
My scenario is one radio button having three items(Left,Right,Center). Now my radio button focus is first radio(Left). Now I click the the tab sequence. It will go to the next field, whether it is input field.
Suppose Now I am come to back ward like shift+Tab it is come to the radio button. Here what is happening mean the focus is going to the Last radio button item(Center), what I want is which radio Item I select Initially ,the Same Place cursor want to go. How to proceed to this. Please give some suggestion to proceed.
Regards,
Ragu

Hi,
so what you are saying is that the tab focus navigation bypasses the other radio buttons whereas tab back focus navigation doesn't. If this is the case, and due to missing information in your question, try this
set autosubmit="true" on the radio group so the radio button selection is saved.
If this doesn't help, please provide information about the implementation of how you created the radio group and which data they are bound to. Chances are that this indeed needs to be filed as a bug but also that it is a problem in your model
