How to return control to a calling jsp

I want to know that can i include a jsp page in another and change the content of the included page whenever the user clicks on a button on the main jsp or the included jsp whatever the case maybe?? please help. thanks

The included page can access the request object from the main page, so on click of a buttun on the main page pass a parameter and depending on this parameter u can change the display of the included page.

How to return control to parent VI

What I want to do is monitor an Abort button and when it goes true I want to stop/close the current VI and return control to the parent VI. I tried using an Application Stop function, but this stops the entire execution and I only want to stop the current VI.
So how can I stop the current VI and turn control back to the parent VI without stopping execution?
Screenshot of the VI that dosn't work is attached.
Thanks in advance.

Dubs,
I second Russ's thoughts that "aborting" a VI is a "bit brute force" and generally not a good programming practice.
I would suggest using while loops coupled with the Elapsed Time VI to create an interruptible wait function similar to what is in the following screenshot:
I hope this helps,

LOVs again! How to return multiple fields to calling form

Hi
Newbie question, any help GREATLY appreciated :)
Is there a simple and easy way to return more than one field from a LOV.
I need this as I have a composite fk comprised of 2 fields, and as such need to return 2 fields from the LOV to the calling form.
(My environment: JDeveloper 9.0.5.2 build 1618)
CM

Thanks, you put me on the right track here. Further investigations show the following sample provided by OTN shows how to use both the session request/response values or a JavaBean to do this:
http://www.oracle.com/technology/sample_code/products/jdev/10g/ADF_UIX_UserInput.zip
As such I post my solution to my original post. Hopefully it's useful to someone beside myself. I have to write up my notes anyhow so it's no fuss to submit them to the forum. I must admit I'm a newbie and slightly demented Forms programmer so such solutions aren't so obvious to me. With this in mind please include the "standard disclaimer" here, with the addition "mileage may vary" warranty.
For these notes I've used the "HR" demo Oracle schema. In particular the tables departments and employees. As you know there is a master-detail relationship between these 2 tables, where each department may have one or more employees.
We have the requirement on a webpage to:
1) Provide an input-form-with-navigation to edit the employees.
2) Display the relating department_name field, rather than just showing the department_id which is meaningless to the user. For example if the employees.department_id = 40, we wish to show the department name "Human Resources" on the employees record.
3) Provide a LOV for the department ID field to allow the user to change the underlying department_id to a different master departments record.
4) Update 2) given a change via 3).
To do this do the following:
Entity Objects
1) Create default EO/VOs on both tables.
2) In the employees EO, create a new field "DepartmentName" to represent the derived department name field.
3) Set the new EO attribute's selected-in-query field.
4) In the query-column-expression field, enter a query to derive the department name field for each record in the detail-employees-EO.
eg. (SELECT dpt.department_name FROM departments dpt WHERE dpt.department_id = employees.department_id)
Ensure to include the brackets.
5) Apply the changes and accept the warning to create default data-type settings for the new attribute.
View Object
6) In the employees VO, include the new field DepartmentName as a selected attribute from the EO.
7) Apply the changes and accept the warning to create default data-type settings for the new attribute.
8) Test the model by running the ADF BC tester. Once running select the employees VO and step through the records, making sure the DepartmentName field has a value and changes appropriately according to the relating parent department_id.
UIX input-only-form
9) Create a new UIX web page employeesEdit.
10) From the data-control pallete, drag in the employees VO as an input-form-with-navigation.
11) For testing purposes it is also useful to have a create, delete, commit and rollback button, so includes these too.
12) Within the employees VO data-control, also drag across a messageLovInput for the DepartmentId. Position it under the existing DepartmentId messageTextInput within the UIX page. We'll remove the existing messageTextInput later, but it's useful to leave it in for testing purposes initially when the LOV returns values.
UIX LOV
13) Navigate to the default LOV page that has just been created for you.
14) Within the data-control pallete, expand the departments VO, select department ID then LOV-table from the drop-down, and drag this item onto the LOV page.
15) Save your changes.
16) Run your application. For an existing employee, invoke the department LOV and select an alternative department. Note on returning to the employees page the DepartmentID (both the messageTextInput and messageLovInput fields) are updated, but the DepartmentName is not. To do this we need to create a JavaBean to return multiple fields from the LOV to the original form.
JavaBean
17) Within your ViewController project, expand the ApplicationSources-View node.
18) Select the new button, and create a standard JavaBean.
19) Name the bean DepartmentsLov.
20) Via the class editor, add 2 private scope fields DepartmentId and DepartmentName with String data-types, ensuring the create get/set method checkboxes are checked.
21) Make and save your changes.
22) From the navigator drag the newly created java file into the data-control palette.
UIX LOV
23) Return to the LOV webpage.
24) Your LOV page will have a lovSelect event handler something like the following:
<event name="lovSelect">
<set property="inputValue"
value="${bindings.DepartmentId.inputValue}"
target="${data.employeesEdit.DepartmentId}"/>
25) Change the lovSelect as follows:
<event name="lovSelect">
<compound>
<set property="inputValue"
value="${bindings.DepartmentId.inputValue}"
target="${data.employeesEdit.DepartmentId}"/>
<set value="${bindings.DepartmentId.inputValue}"
property="inputValue"
target="${bindings.JavaBeanDepartmentId}"/>
<set value="${bindings.DepartmentName.inputValue}"
property="inputValue"
target="${bindings.JavaBeanDepartmentName}"/>
</compound>
26) Within the UI model navigator, right-click on the top node, then create-binding, input, text field.
27) Select the AppModuleDataControl, then DepartmentView, then the DepartmentName field, and then the ok button.
28) In the UI model select the new field, then in the structure pane rename the field to DepartmentName.
29) Within the UI model navigator, right-click on the top node, then create-binding, data, iterator.
30) Select the DepartmentsLovDataControl and name the new iterator DepartmentsJavaBeanIterator.
31) Again in the UI model navigator, right-click on the top node, then create-binding, input, text field.
32) Select the DepartmentsLovDataControl then departmentId field, then the ok button.
33) In the UI model select the new field, then in the structure pane rename the field to JavaBeanDepartmentId.
34) Again in the UI model navigator, right-click on the top node, then create-binding, input, text field.
35) Select the DepartmentsLovDataControl then departmentName field, then the ok button.
36) In the UI model select the new field, then in the structure pane rename the field to JavaBeanDepartmentName.
UIX input-only-form
37) Return to the main employeesEdit UIX form.
38) Your UIX page will have a lovUpdate event handler something like the following:
<event name="lovUpdate">
<null/>
39) Change the lovUpdate as follows:
<event name="lovUpdate">
<compound>
<set value="${bindings.JavaBeanDepartmentId.inputValue}"
property="inputValue"
target="${bindings.DepartmentId}"/>
<set value="${bindings.JavaBeanDepartmentName.inputValue}"
property="inputValue"
target="${bindings.DepartmentName}"/>
</compound>
</event>
40) Repeat steps 29 through 36 for this page.
41) Within the UIX page find the entries for the departmentId LOV, and the DepartmentName. They should look something like the following:
<messageLovInput id="${bindings.DepartmentId.path}"
model="${bindings.DepartmentId}"
destination="lovWindow1.uix"/>
<messageTextInput model="${bindings.DepartmentName}"
columns="10"/>
42) Modify these 2 entries as follows:
<messageLovInput id="DepartmentId"
model="${bindings.DepartmentId}"
destination="lovWindow1.uix"
partialRenderMode="multiple"
partialTargets="DepartmentId DepartmentName"/>
<messageTextInput id="DepartmentName"
model="${bindings.DepartmentName}"
columns="10"/>
43) Finally delete the original DepartmentId messageTextInput field, leaving the DepartmentId messageLovInput.
Testing
44) Open your UIX input-only-form.
45) Call the LOV and change the department for an existing employee record.
46) Return to the employees page and note that the department ID and name have changed.
47) Commit your changes.
48) With your favourite data inspection tool (a'la Toad), check that the employee record's department ID has been appropriately saved to the database.
<The End>
Phew!

Adobe Illustrator API - delay in returning control to calling app?

Hi! We have developed a windows application that adds texts from a XML file to series (hundreds) of EPS files in batch mode by communicating with Illustrator CS4 using the API.
The application runs fine, but rather slow. We found out that the application runs much faster when keeping it’s window active by constantly clicking the main window title with the left mouse button. It seems that after performing a command Illustrator somehow waits some time before returning control to the calling application. A process that can be speeded up by manually activating the calling application with a mouse click. We found a tool that can simulate the mouse clicking, which is a nice work around. However, we would rather find out what causes this behavior and deal with it in the application itself.
Any suggestions?

You need to give a bit more detail about what you are doing if you want to get help.
You say you have written a windows application that communicates with Illustrator "using the API". You also say the application runs faster by "constantly clicking on the main window title" are you talking about the Illustrator window or your applications window?
This forum is about the Illustrator SDK that is used by Illustrator plugins which are not separate applications with their own window.
If your application is really a separate executable with its own window, I am not sure how you are communicating with Illustrator but it sounds like there is a problem in your applications message loop.

How to call jsp after reading from ServletInputStream?

          if the client submit a form including FILE type, I usually use ServletInputStream
          to read it and return next page by calling JSP file. but In weblogic6.0Sp1, the
          server will report a exception: One of the getParameter family of methods called
          after reading from the ServletInputStream(), can't mix these two!
          can anyone help me? thanx a lot.


I've seen these messages in the WLS 5.1.0 logs when POSTing to servlets.
          All the reading is done in the servlet and then a JSP handles the view
          rendering. However, I don't actually call getParameter() or it's kin
          anywhere. I thought maybe something inside the JSP generated servlet is
          calling getParameter(), but I've looked at the generated code and can't find
          any calls. If I had a stack trace it would be easier to sort out.
          Is this a warning or an error? Is there a bad side effect. I imagine the
          getParameter() call would fail.

I would like to know that how can I do for autocommit from jsp. For example, the looping is 10 times which mean I will add 10 records to the db. If the last record is failed to add to db, "how can I rollback the perivious records?" or guide me to set the commit function to handle that case. Thanks a lot for take your time to read my question.

Hello.
The best method is using a session bean and container managed transactions. Other method is using sessions bean and the user transaction object (JTA-JTS).
so, JDBC has transaction management too.
good luck.

How to pass values between applet and jsp

I have a jsp calling an applet which needs to return value to the calling jsp based on the action. Once the applet returns value to the calling jsp, I need to put that value into the session so that I can use it for the other pages. Could anyone have suggestion how to do it. I am new to applet development. Appreciate your help.

Why does it have to send the value back via the same JSP? Why not create a servlet to take input from the applet?

How to call jsp /servlets running in different web application in tomcat

hello all,
i have 2 web applications(Charts and Reports) in the same tomcat,i want to call jsp/servlets running in the Reports webapp from Charts webapp.how do i achieve this.
thanx
ravi

You can also use getContext(String context) in the ServletContext class to get a request dispatcher.
Using the above example it would be :
// in a servlet in the charts webapp
ServletContext context = getServletContext();
ServletContext reportsContext = context.getContext("/reports");
RequestDispatcher dispatcher = reportsContext.getRequestDispatcher("/path")
dispatcher.forward(request, response);Just note, that depending on your server's configuration getContext(...) might return null.

How to Return a value to a 10g Oracle Form form a Web Service Call

I've read the demo available from Oracle, 'Calling a Web service from Oracle Forms', that shows how to invoke a call to a Web Service from a Form. The demo only shows how to do a call and how to display messages. I've done some searching, but can't seem to find any examples of how to return a value from the call into a field on the form. If any one could provide an example of that, I would greatly appreciate it.
We are in the process of modifing a form and we would like to use a webservice, which we have never done before. We have created a webservice which calculates a value based upon what is entered on the form and we want to pass that calculated value back to a field on the form.
This is the code provided by the demo to do a call.
DECLARE
jo ora_java.jobject;
xo ora_java.jobject;
rv varchar2(100);
ex ora_java.jobject;
BEGIN
JO := SendServiceSoapClient.new;
RV := SendServiceSoapClient.sendMessage(JO,:BLOCK3.PHONE_NUMBER, :BLOCK3.MESSAGE_BODY, xo, xo);
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
WHEN ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
message(Exception_.toString(ex));
END;

In the future, please be sure to include the exact product versions you are using. In this case, also be sure to include the java versions you are using to build your java code.

How to call jsp from web dynpro app.

Hi Frndz,
How can I call a JSP from my web dynpro(and here i don't want to redirect to JSP ),I want to call a JSP which can show a message window as alert on top of WDP view.
Here am using CE 7.2 SP1, and my requirement is to call the model(back end) for every minute interval and need to give alert that how many new records r added.With WDP java i haven't find any option to give alert r notifications about new records added, so am thinking to call JSP where I will pass the parameter which can show a alert r notification(like FACEBOOK n outlook notifications).
Please share any ideas ti achieve this,
Thanks in advance.

Hi,
If your application should open in a new url, then you can use link to url action to open jsp.
You can also use EPCF navigation api to call any pcd page as well external links
i.e
WDPortalNavigation
.navigateAbsolute("link",[parameters]);
Since your passing parameters, you build url in both the cases.

(newbie) How to return error messages to JSP page.

Hello,
I'm using a very simple Model 1 architecture (no framework such as Struts used.) The webapp just consists of a login.jsp which collects database connection parameters and then activates a servlet to return a PDF report to the browser.
I have a very common need: I would like the errors entered by the user on the login.jsp to be displayed at the top of a new return of the login.jsp (with the bottom of the JSP still providing the edit fields for reentry), errors such as:
1.) User did not enter the username, password, and database name
2.) Having a wrong username/password for the given database.
(2) is more complex than (1), because it would involve feedback from the servlet (which makes the DB connection).
I'm not sure how to code this, however, with just JSP, JSTL and JavaBeans. Does anyone know of an example with source code on the web where something similar to this is done?
Thanks,
Glen

No problem on posting here. Seeing as JSP forum is not accessible, this is the next best choice.
What sort of complexity are you after here?
You can go with the very simple:
Print out the error messages as you discover them.
if (request.getParameter("username") == null){
// print out the message
out.println("Please enter your username");
// or alternatively
List errors = new ArrayList();
errors.add("Please enter your username");

How to call JSp from Servlet??

Hello,
I want to call JSP page from servlet.I am using Visual Age For java 3.4. What is wrong in my code??
if (userExists) {
f.setErrors("userName","Duplicate User: Try a different username");
getServletConfig().getServletContext().
getRequestDispatcher("/jsp/forms/retry.jsp").
forward(request, response);
I am not able to get the o/p. Pls help.

I can't see anything obvious, but did you take any steps towards doing output before this code (like openning an output stream)?
Not clear what f.setErrors does - presumably stuffs the error message in an attribute of the request.
