Acess and execute method in AppModule

Hi !
I'm creating a filter for one aplication web and trying to access a method of my ManegedBean but I can not.
This method accesses a binding but is returning a nullpointer when you try to retrieve the binding.
How do I access a method in my class AppModuleImp by accessing the filter?
I am developing in ADF 11g
Thanks,
Vinicius

If the question is how to access ApplicationModule from your backing bean, then probably below steps may help you
1. Create bdinding to the AM method , by editing page definition corresponding to your jsf
2. Code Snippet to execute AM method:
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
OperationBinding ob = bindings.getOperationBinding("yourMethodd");
Object result = ob.execute();
if (!ob.getErrors().isEmpty()) {
return something;
return somethingElse;

How populate and execute methods gets called in UserDefined Action Classes?

In Struts2, if we override methods populate() and execute() , then if we made any request to some Action class which overrides these methods, then how does it look for these 2 methods??
and why populate() method called first and later execute() method????

Thanks for this. Alas, I do not have the source code used to generate the jar file, and I have no means of getting it. I imagine, therefore, that I will not be able to update the manifest file.The manifest file is just a simple text file.
You can get at it by unpacking/repacking the jar file with the jar utility (tar like syntax).
... I assume that classpath is rather like the unix path.It specifies a list of jar files and directories containing java class files (and more).
Is there anything that defines the classpath for each login session and, if so, how do I add to it?As the link I posted says;
you can set a CLASSPATH env.var.

PreparedStatement and execute() method

Hi to all.
I would like to understand a thing.
Why the execute() method gives me back false also if the SQL instructions is well executed?
Is this right?
TIA
Omar

Returns:
true if the first result is a ResultSet object; false if the first result is an update count or there is no result

How can i disable a submit button and execute submit_action method on click

Good Day,
On my page I have a submit button that execute the submit_action method of the page backing bean that submit data captured on the page into a database and activate another class that send mail at the same time on a click of the submit button,the mail process takes a while before returning back to the page.I was able to disable the submit button to prevent the user from keep click while the process is running but the issue is on clicking the submit button it only disable the submit button without executing the submit_action method of the page backing bean.How can i disable the submit button and execute submit_method of the backing bean at the same time.
Thanks in advance.

I tried this out on one of my pages to see if it works.
First, I added the following JavaScript to my submit button's onClick event:
this.disabled=true; return true;When I clicked the submit button, it was disabled but the form was not submitted.
I deleted the JavaScript from the onClick event and added the following JavaScript to the form's onSubmit event:
var button = document.getElementById("form1:submitButton"); button.disabled=true; return true;When I click the submit button, it was disabled and the form was submitted but the button's action method was not called.
The next thing I tried was to change the onSubmit event code:
var button = document.getElementById("form1:submitButton"); setTimeout("button.disabled=true", 500); return true;This seemed to work. The difference was that I added a 1/2 second delay before disabling the button.
See if that works for you. If not then I'm fresh out of ideas.

I have a VI A. I want A to call another VI B and execute. After B executes, I want it to close automatically and go back to A. Is this possible ? I tried using open reference and those methods, but I am not able to do it. Can someone help me ? Thanks !

Thanks !
Kudos always welcome for helpful posts

I tried using open reference and those methods, but I am not able to do it. Can someone help me ? Thanks !Hi Stephan ! Thanks ! I guess I explained my question not so right. I've created a customized menu and at the instance of me selecting a menu, a VI should load itself dynamically. I am using call by reference. Sometimes it works and sometimes it won't. In short, what I want to achieve is load VIs dynamically and close them dynamically once they finish executing. Thanks !

Is there such thing as a "compile and execute statement" in Java?

I wanted to know if there's any way to compile and execute a program "within" another program.

Yes, but the classes to do so aren't officially supported by Sun as far as I know.
And you must be able to assume a thing or two about the stuff you compile, such as existing constructors or factory methods etc, otherwise it gets hairy.
Here's some example code (haven't tried it, so excuse any spelling errors etc) to compile the source code in a file called MyClass.java:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
new sun.tools.javac.Main(baos,null).compile("MyClass.java");
String theMsg = baos.toString();
if (theMsg.length() > 0)
// NiftyErrorHandlingHere
}After that, you can load it with a simple ClassLoader.loadClass() call and create instances of it.
It must be compiled with the tools.jar file in the classpath, to find the sun.tools.javac.Main class.
However, for any such dynamically compiled class to be of any use to you, you must be able to assume something about it, such as implementing interfaces or whatever, otherwise it's a kind of pointless exercise.

Error when I call a method of AppModule from a backing bean.

I use Jdeveloper 10.1.3.0.3 EA.
In my application I have created ApplModule and UsrView(for my table USR).
I have a login page (login.jsp and the backing login.java) with 2 fields userName and password and an ADF Faces Core command button (cmdCheckPass) and the method cmdCheckPass _action() for the click event .
The problem is that I cant call method testPassword(userName, password) which is written in AppModule. (I get error:
javax.faces.FacesException: #{backing_login.cmdCheckPass_action}: javax.faces.el.EvaluationException: java.lang.NullPointerException) from line:
answer = app.testPass(st1,st2);
The code is as follows:
public String cmdCheckPass_action() {
String answer="";
String mes = "";
String st1=this.getInputText1().getValue().toString();
String st2=this.getInputText2().getValue().toString();
AppModuleImpl app = new AppModuleImpl();
answer = app.testPass(st1,st2);
if (answer == "OK") {
return "toMain";
} else {
answer = "";
mes="Invalid username, password !!!";
FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(mes));
return answer;}
I dont know if theoretically is right to call, from a backing bean, a custom method of AppModule.
Can I have any help on this?
Thanks in advance,

Some quick ideas:
Is the clip the same NTSC/PAL standard as the project you are importing it to?
Have you tried to rename the offending clip (do NOT rename any clips inside the iMovie /Media folder!!).
How much free space do you have on the iMovie project volume -- what is the size of the imported clip?

Using value selected in selectOneChoice as variable for execute method

I have already created data controls for the session bean method so I can drag and drop on to the jsp. This works fine when entering the data into the input text fields but I really need the first value to come from an initial page and the second value to come from the dropdown. I just don't know how to get the value or how to connect it to the button for execution.
The method takes two values
value 1, org is passed in (how do I pass from another page? I will actually have the render for this input field set to false so it does not display)
value 2, typeId from a selectonechoice drop-down list (how do I manipulate the soc to pass the information? Currently it looks as if it is just passing the elementAt number, I need get the actual value for the item selected. Where can I retrieve it?)
I have a button ready to execute the method on the session bean which should take these values. (of course the inputvalue for the soc was not typeId but I changed it. The values for the soc are actually coming from another method performed earlier.)
This is what I have so far:
I have my input text field waiting on info to be populated from the previous page (currently I manually entered it)
I have my selectonechoice populated
A button with the execute method already set (b/c I initially used the drag-drop functionality to test my method)
Forgive me for repeating myself so much.
Thanks!

Oracle ADF Find and Execute in form

Hi,
I have followed the blog for creating a form which allows for searching. I am executing the Find operation on the viewiterator to enter into query mode at the time of launching the form (in pagephaselistener calling managed bean method and the method executes the OperationBinding.execute to execute the find operation). The view does not have any bind variables, It is a simple view on the table with out any mandatory fields. Then I executed "execute" operation using OperationBinding based on an event in the page by entering the query criteria on the page for a textfield. This is working fine and it is returning the matching records for the query criteria. So far it is good.
http://andrejusb.blogspot.com/2008/09/jdeveloper-11g-crud-in-adf-form.html
But the problem is when there are mandatory fields. My expectation is to execute the query based on the event in the UI even the mandatory fields are not filled. Let us say If the view object is having 4 mandatory columns and the user enters only 1 column it should perform the query and populate the fields. Could you please sugggest.
The behavior should be some thing similar to Oracle forms enter query and execute query modes for the same form fields.
Thanks and Regards,
S R Prasad

You're hitting a bug. See ADF Faces Classical Search Form works only with Entity base VO in JDev 11? for a workaround suggestion.

How to invoke BASH shell and execute a command in that shell in Windows 98

Hello, I have a problem and if somebody will help me, I will be very glad. Thank you.
I am using BASH shell on Windows 98 OS by means of CYGWIN. And I want to invoke this BASH shell and execute a preprogrammed command in the shell (./scan fileName.txt) from a JAVA program. But so far, I am not sucessful. I can not read or write anything from / to BASH shell. It either blocks and freezes (When I use waitFor( ) ) or appears and disappears without executing scan command (When I do not use waitFor( ) ). My code is like this:
// This method is used for compiling a file.
// It invokes BASH shell and executes "./scan fileName.txt" command
public void compileFileMethod () {
try {
Process proc = ( Runtime.getRuntime() ).exec ("C:\\MyDocuments\\CYGWIN.BAT); //I also tried to add -c ./scan fileName.txt after .BAT );
// I also tried to write "C:\\MyDocuments\\BASH.EXE" but it did not help
OutputStream ostr = proc.getOutputStream();
BufferedWriter bw = new BufferedWriter ( new OutputStreamWriter (ostr) );
InputStream istr = proc.getInputStream();
BufferedReader br = new BufferedReader ( new InputStreamReader (istr) );
InputStream errorStr = proc.getErrorStream();
BufferedReader errorBr = new BufferedReader ( new InputStreamReader (errorStr) );
bw.write("scan case40.10.txt"); /* I am trying to input the scan command to the shell,but it is not working*/
bw.flush();
Vector list = new Vector (1) ;
String str;
while ( (str = br.readLine() ) != null) {
list.addElement(str);
} // End of while
Enumeration enumForList = list.elements();
while ( enumForList.hasMoreElements() ) {
String tempString;
tempString = ( String ) enumForList.nextElement();
System.out.println(tempString); // I am trying to read the outputs of the scan command but it is not reading (I can not see any output)
I tried with and without waitFor( ), it did not work
// wait for command to terminate
proc.waitFor();
// close streams
br.close();
bw.close();
errorBr.close();
} // End of try
catch ( IOException ioe ) {
JOptionPane.showMessageDialog (null, "Input / output error occured while compiling file ", "Error", JOptionPane.ERROR_MESSAGE);
} // End of catch
catch ( SecurityException se ) {
JOptionPane.showMessageDialog (null, "Security error occured while compiling file ", "Error", JOptionPane.ERROR_MESSAGE);
catch ( InterruptedException ie ) {
JOptionPane.showMessageDialog (null, "Interruption error occured while compiling file ", "Error", JOptionPane.ERROR_MESSAGE);
} // End of method compileFileMethod
// Thank you for your helps and time.

You cannot invoke BAT files directly, you have to invoke the program that run those files which is your Windows 98 shell. For example (under windows 2000), i would invoke "cmd.exe sricpt.bat some args", rather than "script.bar some args".
Hope this will help you out.

Why does a find and replace method remove whitespace?

I have method that searches for a string in a FM document and replaces it with a variable. If for example, there was a string foobar that I wanted to replace with the variable barfoo. Then, I expect this text:
Lorem ipsum dolor sit amet, foobar consectetur adipiscing elit. Vivamus sed purus urna, ac tristique tortor. Nam auctor tellus non enim pulvinar a vestibulum neque tincidunt.
To be changed to this text:
Lorem ipsum dolor sit amet, barfoo consectetur adipiscing elit. Vivamus sed purus urna, ac tristique tortor. Nam auctor tellus non enim pulvinar a vestibulum neque tincidunt.
However, while the text does do the replace it also removes the whitespace between the variable and the text that appears right after the variable so it actually looks looks like this:
Lorem ipsum dolor sit amet, barfooconsectetur adipiscing elit. Vivamus sed purus urna, ac tristique tortor. Nam auctor tellus non enim pulvinar a vestibulum neque tincidunt.
Why is the find and replace method removing the whitespace and how do I prevent that from happening? The method is provided below.
function FindAndReplaceString(pDoc, findString, replaceVariable)
    if (typeof pDoc != 'undefined'&&typeof findString != 'undefined'&&typeof replaceVariable != 'undefined'&&pDoc.ObjectValid()&&findString.length>0&&replaceVariable.length>0)
        var vVarFmtStatus=checkVarFmStatus (pDoc, replaceVariable);
        if (vVarFmtStatus=='In Doc')
            var tr = new TextRange();
            var findParams = new PropVals();
            var frame = pDoc.MainFlowInDoc.FirstTextFrameInFlow;
            var restoreTR = pDoc.TextSelection;
            tr.beg.obj = tr.end.obj = frame.FirstPgf;
            tr.beg.offset = tr.end.offset = 0;
            findParams = AllocatePropVals(1);
            findParams[0].propIdent.num = Constants.FS_FindText;
            findParams[0].propVal.valType = Constants.FT_String;
            findParams[0].propVal.sval = findString;
            tr = pDoc.Find(tr.beg, findParams);
            var vLoopCounter=0;
            while(FA_errno === Constants.FE_Success&&vLoopCounter++< 1000)
                pDoc.TextSelection = tr;
                pDoc.Clear(0);
                var newVar = pDoc.NewAnchoredFormattedVar(replaceVariable, tr.beg);
                var varLength = newVar.TextRange.end.offset - newVar.TextRange.beg.offset;
                tr.beg.offset += varLength;
                tr = pDoc.Find(tr.beg, findParams);
            if (vLoopCounter>0)
                Log (vLogFileName, 'In the document \''+pDoc.Name+'\', the string \''+findString+'\' was replaced with the variable \''+replaceVariable+'\' '+vLoopCounter+' times.\n')
            if (vLoopCounter>1000)
                recordErrors (vErrorLog, 'ERROR: In the document "'+pDoc.Name+'", the find and replace operation was stopped after executing '+vLoopCounter+' times. The term being searched for is "'+findString+'" the replacement variable is "'+ replaceVariable+'".')
            pDoc.TextSelection = restoreTR;
            pDoc.ScrollToText(restoreTR);
            } else {
                recordErrors (vErrorLog, 'ERROR: The find and replace operation failed because the variable '+replaceVariable+' does not exist in the following doc: '+pDoc.Name)
        } else {
            recordErrors (vErrorLog,'Invalid or unitialized parameter passed to function FindAndReplaceString')

Working with class based exception and dynamic method calls

Hi Gurus,
we just changed out ERP from EHP6 to EHP7.
Since we did so we are facing an issue with an Z-Report we are using quite often.
This reports looks up Workitems and executes the according methods so that we can go into debugging if we were facing any problems or errors.
since the EHP Upgrade this statement has problems:
data: lt_parmbind type abap_parmbind_tab, lt_excpbind type abap_excpbind_tab, lo_runtime type ref to object. call method lo_runtime->(iv_cls_method) parameter-table lt_parmbind exception-table lt_excpbind.this CALL METHOD Statement has Problem with the Exception Table. We are quite often getting DYN_CALL_METH_EXCP_NOT_FOUND short dumps with Exception "CX_SY_DYN_CALL_EXCP_NOT_FOUND".
The system has problems handling the content of lt_excpbind. if i clear this table the CALL METHOD statement works fine.
AS an example we are trying to call /IDXGC/CL_PD_PROCESS_STEPS-->CREATE_DATA. This method has 2 exceptions
/IDXGC/CX_PROCESS_ERROR
Process Layer Exception
CX_BO_TEMPORARY
Temporary Business Exception
The Content of LT_EXCPBIND is
INDEX
NAME
VALUE
2
/IDXGC/CX_PROCESS_ERROR
1
2
CX_BO_TEMPORARY
2
From my point of view the Problem ist, that they are marked as "class based". I think so because if you looked up the SAP Help for the EXCEPTION-TABLE Statement it is written that is statement only works for none-classbased exception.
I think that restriction is quiet clear. But what i am wondering about is.. that restriction also exists for EHP6. And in EHP6 it work. Does anyone know why? Or how i can change me CALL METHOD Statement that i will work again?
Best Regards
Udo

Class-based exceptions must be caught using try/catch statement.
Calling dynamically a method catchable exceptions are:
CX_SY_DYN_CALL_EXCP_NOT_FOUND
CX_SY_DYN_CALL_ILLEGAL_CLASS
CX_SY_DYN_CALL_ILLEGAL_METHOD
CX_SY_DYN_CALL_PARAM_MISSING
CX_SY_DYN_CALL_PARAM_NOT_FOUND
CX_SY_REF_IS_INITIAL
Anyway catching cx_root (as shown by Matthias) will catch everything is catchable.

Execute() Method is undefined

Hi all.
I am developing a WebDynpro Application which will use a EJB for business logic. I am using a javabean as interface between EJB ane WebDynpro. I created a instance of model in webdynpro and i am trying to retrive the data from backend. But in webdynpro, while writing the execute() method, it displaying that execute() method is undefined for this type.
Kindly give some suggessions to rectify this.

Hello Pavan,
Is your EJB Bean which is having execute method is in classpath ? Is those Home interface and all are in Proper place?
Thx & Rgds

Accessing Custom Controller from setter and Getter methods

Hi Gurus
How can we access the custom controller from setter and getter methods,is there any way to do that.
Thanks & Regards
Rajasekhar

Hi Steve.
Thanks very much for valuable information, the main controller class is getting tracked in mo_owner which is declared as CL_BSP_WD_VIEW_CONTROLLER, and I'm getting the reference through
mo_owner ?= owner. (since mo_owner = owner is not getting converted of type mo_owner ). After doing this on whatever the contexnode class (say zl_xxxx_xxx_cnxx) the corressponding context node values are getting turned as <#ERROR IN METADATA.
I mean when I'm checking the configuration in bsp_wd_cmpwb configuration tab -> Available Fields->Enlarge the contex node->BTSTATUS (say for Example) there the values are showing as <#ERROR IN METADATA , After executing the above procedure
I cross checked several times before and after redefining the context node method IF_BSP_MODEL~INIT, before redefining this method UI is working fine, after redefintion UI is throwing below error .
Exception Details
CX_SY_REF_IS_INITIAL - Dereferencing of the NULL reference
Method: CL_BSP_MODEL=>IF_BSP_MODEL_BINDING~IS_ATTRIBUTE_VALID

Executing Method on pageload

Hello,
I'm looking for a solution to execute a method on a backing bean, when a view is loaded. Well I could workaround that with using a commandButton to link to the page and execute the method as an action handler, but that's not really an elegant solution.
Good ideas highly appreciated!
Best regards,
Timo Elverkemper

hallo little
hope u find the answer from the below desc.
phaselistener is called for every page load...
JSF PhaseListener - Is This User Logged In?
JavaServer Faces (JSF) is being touted as the next generation of web application development from the powers that be (IBM, Sun, Oracle), and has been tugging at my interest the past 8 months. In my quest to use it I quickly found myself drowning in the different complexities, but through much head to wall banging I have prevailed and would like to share some of those experiences with you through tips.
This tip shows how to register a PhaseListner at the Restore View phase of the JSF Lifecycle. The PhaseListener checks to see if the user has logged in, and if not it returns them to the login page. One could check to see if a user is logged in on each page and have code duplicated across many different backing beans, but going the PhaseListener route guards against that and allows you to have one point of checking for login credentials. To learn more about the JSF Lifecycle point your browser to http://www.javaworld.com/javaworld/jw-11-2002/jw-1129-jsf-p2.html
Figure 1 shows how to register the PhaseListener using the lifecycle and phase-listener tags. This should be placed in your faces configuration file, often named faces-config.xml.
Figure 1
<lifecycle>
<phase-listener>com.loffler.copycenter.controller.LoggedInCheck</phase-listener>
</lifecycle>
Figure 2 shows Java class LoggedInCheck implementing PhaseListener. The method getPhaseId is used to tell the PhaseListner which lifecycle phase this class should be called. In this example PhaseId.RESTORE_VIEW is used. You will have to understand the different phases to make sure a particular one fits for you. This one works in this case because it happens after backing beans have been updated form data from the web page.
Figure 2
package com.mowyourlawn.controller;
import javax.faces.application.NavigationHandler;
import javax.faces.context.FacesContext;
import javax.faces.event.PhaseEvent;
import javax.faces.event.PhaseId;
import javax.faces.event.PhaseListener;
public class LoggedInCheck implements PhaseListener {
    public PhaseId getPhaseId() {
        return PhaseId.RESTORE_VIEW;
    public void beforePhase(PhaseEvent event) {
    public void afterPhase(PhaseEvent event) {
        FacesContext fc = event.getFacesContext();
        // Check to see if they are on the login page.
        boolean loginPage =
          fc.getViewRoot().getViewId().lastIndexOf("login") > -1 ? true : false;
        if (!loginPage && !loggedIn()) {
            NavigationHandler nh = fc.getApplication().getNavigationHandler();
            nh.handleNavigation(fc, null, "logout");
    private boolean loggedIn() {
        return LoginController.loggedIn().booleanValue()c;
Figure 3 shows what happens when a from-outcome of �logout� is encountered. Reference the nh.handleNavigation(fc, null, "logout"); line of code in Figure 2 to understand how the two are related. Again this should be placed in your faces-config.xml file.
Figure 3
<navigation-rule>
<from-view-id>*</from-view-id>
    <navigation-case>
      <from-outcome>logout</from-outcome>
      <to-view-id>/login.jsp</to-view-id>
    </navigation-case>
</navigation-rule>
