Question on "How-to invoke a method once upon application start"

Hello everyone.
I'm trying to implement what the article "How-to invoke a method once upon application start" by Frank suggests.
https://blogs.oracle.com/jdevotnharvest/entry/how_to_invoke_a_method
Suppose that I'm having a single point of entry, so in my login.jpsx I have the below:
<f:view beforePhase="#{login.onBeforePhase}">In the method "onBeforePhase" I have to pass the phaseEvent, since the signature is the following:
public void onBeforePhase(PhaseEvent phaseEvent)but how do I know the phaseEvent when calling the login.onBeforePhase? How the call should be?
Thanks a lot!
ps. I'm using jDev 11.1.2.1.0

You need not pass anything to this method , this method will get called before every Phase except ReStore View
Just write the logic as Frank suggested for the phase in which you want the code to execute. You can get the PhaseId's like
PhaseId.RENDER_RESPONSE
public void onBeforePhase(PhaseEvent phaseEvent) {// from Frank's doc
//render response is called on an initial page request
if(phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE){
... etc

How to use " toFront() " method in java application and in which package or

How to use " toFront() " method in java application and in which package or class having this toFront() method.if anybody know pl. send example.

The API documentation has a link at the top of every page that says "Index". If you follow that and look for toFront(), you will find it exists in java.awt.Window and javax.swing.JInternalFrame.
To use it in a Java application, create an object x of either of those two classes and write "x.toFront();".

How to invoke a method in application module or view objects interface?

Hi,
perhaps a stupid RTFM question, but
How can i invoke a method that i have published in the application modules or view objects interfaces using uiXml with BC4J?
Only found something how to invoke a static method (<ctrl:method class="..." method="..." />) but not how to call a method with or without parameters in AM or VO directly with a uix-element.
Thanks in advance, Markus

Thanks for your help Andy, but i do not understand why this has to be that complicated.
Why shall i write a eventhandler for a simple call of a AM or VO method? That splatters the functionality over 3 files (BC4J, UIX, handler). Feature Request ;-)?
I found a simple solution using reflection that can be used at least for parameterless methods:
<event name="anEvent">
<bc4j:findRootAppModule name="MyAppModule">
     
      <bc4j:setPageProperty name="MethodName" value="myMethod"/>
      <ctrl:method class="UixHelper"
              method="invokeApplicationModuleMethod"/>
   </bc4j:findRootAppModule>
</event>The UixHelper method:
public static EventResult invokeApplicationModuleMethod( BajaContext context,
                                                           Page page,
                                                           PageEvent event ) {
    String methodName = page.getProperty( "MethodName" );
    ApplicationModule am = ServletBindingUtils.getApplicationModule( context );
    Method method = null;
    try {
      method = am.getClass( ).getDeclaredMethod( methodName, null );
    } catch( NoSuchMethodException e ) {
      RuntimeException re = new RuntimeException( e );
      throw re;
    try {
      method.invoke( am, null );
    } catch( InvocationTargetException e ) {
      RuntimeException re = new RuntimeException( e );
      throw re;
    } catch( IllegalAccessException e ) {
      RuntimeException re = new RuntimeException( e );
      throw re;
    return null;
}Need to think about how to handle parameters and return values.
Btw. Do i need to implement the EventHandler methods synchronized?

How to invoke action method from mail contained link

Hello,
my application needs to send mails to users that include links for the user to click on. Something like www.mysite.com/displayData.jsp&id=123. My question is now how I make JSF invoke the respective method in the backed bean to display the data with the id 123 when the user clicks on the link int the mail.
I wonder whether there is some kind of "catch-all action" that checks whether the user is logged in and authorized whenever any JSP page is invoked. I'm a bit tired of first checking the authorization of some user before processing the remaining part od the backed bean's action method.
Thanks for any hints,
Oliver Plohmann

Urgent please ! How to invoke java method with diffrent argument types?

Hi,
I am new to JNI.
I had gone through documentation but it is not of much help.
Can any one help me out how to invoke the below java method,
// Java class file
public class JavaClassFile
public int myJavaMethod(String[] strArray, MyClass[] myClassArray, long time, int[] ids)
// implementation of method
return 0;
// C++ file with Invokation API and invokes the myJavaMethod Java method
int main()
jclass cls_str = env->FindClass("java/lang/String");
jclass cls_MyClass = env->FindClass("MyClass");
long myLong = 2332323232;
int intArray[] = {232, 323, 32, 77 };
jclass cls_JavaClassFile = env->FindClass("JavaClassFile");
jmethodID mid_myJavaMethod = env->GetMethodID( cls_JavaClassFile, "myJavaMethod", "([Ljava/lang/String;[LMyClass;J[I)I");
// invoking the java method

//jint returnValue = env->CallIntMethodV( cls_JavaClassFile, mid_myJavaMethod, ...........); --- (3)
Can any one tell me what is the correct way of invoking the above Java method of (1), (2) and (3) and how ?
The statement (1) is compilable but throws error at runtime, why ?
How can I use statements (2) and (3) over here ?
Thanks for any sort help.
warm and best regards.

You are missing some steps.
When you invoke a java method from C++, the parameters have to be java parameters, no C++ parameters.
For example, your code appears to me as thogh it is trying to pass a (C++) array of ints into a java method. No can do.
You have to construct a java in array and fill it in with values.
Here's a code snippet:
jintArray intArray = env->NewIntArray(10); // Ten elments
There are also jni functions for getting and setting array "regions".
If you are going to really do this stuff, I suggest a resource:
essential JNI by Rob Gordon
There is a chapter devoted to arrays and strings.

Hi,
you cannot invoke the showPopupBehavior component action programatically. Instead, to programatically launch a popup, you use client side JavaScript as explained in the WebDeveloper guide http://download.oracle.com/docs/cd/E12839_01/index.htm . Note that the JavaScript can be launched from a managed bean

How to invoke a method in JApplet from javascript.

We want to invoke a method in JApplet from javascript.
with the help Java Plug-in HTML Converter Version 1.3, we have generated OBJECT/EMBED tag for
the following applet tag.
<APPLET CODE = "SimpleApplet" WIDTH = 200 HEIGHT = 300 NAME = "simpleApplet"
MAYSCRIPT = true>
<PARAM NAME = "p1" VALUE = "v1">
</APPLET>
it is given the following code


<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"

But, even after trying to invoke method in the JApplet from javascript, it is not being invoked in
Netscape. it is being invoked from
IE after changing the scriptable = true. Is there any such parameter to change, to invoke the
method in JApplet from javascript?
can anybody give any suggestion?

hi there,,
well the same problem exists with my code also, NS fails to call the function from java applet... if u get the answer please mail me on [email protected]

How to invoke bean method after query executed?

Jdeveloper 11.1.1.2:
I have a bean that backs a JSF page.
The bean has a method that shows/hides certain GUI components based on the values of other components.
I would like to invoke this method automatically after the page has been fully loaded.
I tried invoking the method in the AfterPhase of the f:view and at bean construction time. Both approaches failed.
I think I need a listener that gets invoked after the query has been executed.
Any idea?
thanks

Hi,
if the bean is a backing bean and it is supposed to hide components, then why don't you create a reference of the components to the backing bean so that the displayed property is dynamically evaluated ? Sounds like this is what you want to do

How to show asterisk * effect once the user starts editing the document??

I wrote a java text editor. I creat a new internal frame and allows to open a document.
How to have an effect (an asterisk * follows the filename in title bar) once
the user starts editing the document? And once I save that file, that asterisk * will
disappear. It seems to me we need to add a listener, but not sure how to change
the title bar of internal frame??

just use DocumentListener like
myTextArea.getDocument().addDocumentListener(new DocumentListenet(){
public void changedUpdate(DocumentEvent e){
frame.setTitle( frame.getTitle() + "*" );
implements two other methods too

How to invoke AM method that accepts parameter other than string

Hi
I need to pass 2 date parameters to my AM method.
I checked the jdev doc and found the below method that can be used for any of the parameter other than String
public Serializable invokeMethod(String methodName,
Serializable[] methodParams,
Class[] methodParamTypes)
one thing i am not able to understand is how to pass multiple dates in a single Class parameter.
can anyone tell me the invoke method syntax for passing 2 dates.

Hi,
Suppose you have a string and two date parameters
String test;
Date date1;
Date date2;
then pass it like this
OAApplicationModule am = pageContext.getApplicationModule(webBean);
Serializable parameters[] = {test,date1,date2};
Class paramTypes[] = {String.class,Date.class,Date.class};
am.invokeMethod("initSummary", parameters, paramTypes);

How to invoke Java method from C++

Hi
My requirement is In C++ we are having three different structures, like
struct one{
int accontno;
char * accountholdername;
long balance;
struct two{
int startdate;
int enddate;
struct three{
char* userid;
char* userpassword;
from c++ how to pass these structures, these structures I have to read in Java class, and in java how receive these structures.
And the sample methods will be like: getCarsData(Input, output, Error);
How do i call the method in JNI, if it is static int method we can call like
getStaticIntMethodID(), instead of int if i have to pass the above mentioned structures how do i do? Should i create an object array in JNI for accessing these three structures?
Suggestions/Samples welcome
Thanks,

Why did you start another thread for this?
I was answering you in the [url http://forum.java.sun.com/thread.jspa?threadID=712137&messageID=4119725#4119725]old thread and you didn't even bother to answer back my (basic) questions.
I told you to use the code tags when pasting code. Got ignored. I also gave you a starting example on how to achieve your goal. Flushed.
Oh well, I'm getting used to it.
Again.
Before starting, allways keep near you the [url http://java.sun.com/j2se/1.5.0/docs/guide/jni/spec/jniTOC.html]JNI reference. All the JNI functions are documented in it.
First you need to create custom Java classes that will match the C++ stucts (remember?).
There is no magic wand in JNI that will transform the C++ structs into the custom Java classes and vice versa.
You'll have to code it by hand, one field at a time. It's a pain.
So for the one, two, three C++ structs (why not posting some real names instead of this crap?),
there will be JOne, JTwo and JThree Java classes.
There is also that other Java class already existing with getCarsData() static method that will fetch the data.
And finally the DLL function wich will call this Java static method, doing the bridge between the C++ structs and the custom Java classes, finally return the data.
Due to the lack of explanation from your posts, I will say that the getCarsData() static method receives a parameter of type JOne
and returns an array of JTwo objects.
So the get_cars_data() DLL function receives a parameter which is a struct one and
returns a pointer to an array of struct two elements.
// C++ structs
struct one {
    int accontno;
    char * accountholdername;
    long balance;
struct two {
    int startdate;
    int enddate;
struct three {
    char * userid;
    char * userpassword;
// custom Java classes
class JOne {
    int accontno;
    String accountholdername;
    int balance;
class JTwo {
    int startdate;
    int enddate;
class JThree {
    String userid;
    String userpassword;
// Java class with static method that gets the data
class DataFetcher {
    static JTwo[] getCarsData(JOne one) {
// DLL function
// struct 'one' parameter is already filled with values.
// Returns an array of 'two' C++ struct obtained from a Java static method
two * get_cars_data(one o) {
    JNIEnv * env;
    /** not show here is the code to either
        create the JVM or
        attach it to the current thread **/
    // get the data from 'one' C++ struct and put it in a new instance of JOne Java class
    jclass oneCls = env->FindClass("JOne");
    jmethodID oneCtorID = env->GetMethodID(oneCls, "<init>", "()V");
    jfieldID accontnoID = env->GetFieldID(oneCls, "accontno", "I");
    jfieldID accountholdernameID = env->GetFieldID(oneCls, "accountholdername", "Ljava/lang/String;");
    jfieldID balanceID = env->GetFieldID(oneCls, "balance", "I");
    jobject oneObj = env->NewObject(oneCls, oneCtorID);
    env->SetIntField(oneObj, accontnoID, o.accontno);
    env->SetObjectField(oneObj, accountholdernameID, env->NewStringUTF((const char *)o.accountholdername));
    env->SetIntField(oneObj, balanceID, o.balanceo);
    // call the Java static method
    jclass dfCls = env->FindClass("DataFetcher");
    jmethodID getCarsDataID = env->GetStaticMethodID(dfCls, "getCarsData", "(LJOne;)[LJTwo;");
    jobjectarray twoArray = (jobjectarray)env->CallStaticObjectMethod(dfCls, getCarsDataID, oneObj);
    // create the 'two' C++ struct array from the Java array of JTwo objects
    jclass twoCls = env->FindClass("JTwo");
    jfieldID startdateID = env->GetFieldID(twoCls, "startdate", "I");
    jfieldID enddateID = env->GetFieldID(twoCls, "enddate", "I");
    jint len = env->GetArrayLength(twoArray);
    two * pt = new two[len];
    for (int i = 0; i < len; i++) {
        jobject twoObj = env->GetObjectArrayElement(twoArray, i);
        pt.startdate = env->GetIntField(twoObj, startdateID);
pt[i].enddate = env->GetIntField(twoObj, enddateID);
// return the resulting 'two' C++ struct array
return pt;

How to invoke updateDisplayList method in the custom layout?

I've a group of buttons that get placed in a SkinnableDataContainer with the help of a custom layout class as follows:
<s:SkinnableDataContainer id="buttonsContainer"
    dataProvider="{appModel.myButtons}"
    width="{DIAPLAY_WIDTH}" height="{BUTTON_HEIGHT+4}"
    skinClass="view.skins.ContainerSkin"
    itemRenderer="view.renderer.MyButtonRenderer"
    click="startPointAreaClickHandler(event)"
    mouseMove="areaMouseMoveHandler(event)"
    mouseUp="areaMouseUpHandler(event)"
    rollOut="areaMouseOutHandler(event)"
    >
    <s:layout>
        <layout:ButtonsLayout />
    </s:layout>
</s:SkinnableDataContainer>
myButtons is an ArrayCollection of VOs and VO has x and y coordinates as fields. Values of x and y determine the location of the button. When I add an object to myButtons, the application behaves as expected (adds a button in buttonsContainer at specified x and y coordinate). But when I just change values of x and y of an existing button, the buttons don't get repositioned. I have tried calling invalidateDisplayList on buttonsContainer but that doesn't trigger updateDisplayList method in the custom layout ButtonsLayout.
How do I trigger updateDisplayList method in the custom layout so that the button positions get updated whenever an event changes values of x and y of a button?

Hi Balus,
This is helpful but one problem i faced with this is, when i overided the custom message in the property file,
javax.faces.component.UIInput.REQUIRED =Value is required
but for every UIInput component the same message is coming, but if i am having more than one component on the page forexample: UserName , Email, Password etc...
i need to display messages like
Value is reuired for UserName
Value is reuired for Password
Value is reuired for Email
How this is possible , can u please help me.
Thank You,
