How to invoke a class or methods simultaneously

Hi
how can an class object or method invoke simultaneously for n numbers.
eg:
invoke() // method to be invoked 5 numbers
praks

What do you mean? You want to start 5 threads at the same time? You can start them and let them wait on an object. Then you call notifyAll. It think this is the closest to a simultaneous start you can get.

How do I access classes and methods defined in a wsdl file

I have been provided a wsdl file I need to find out how do I access classes and methods defined in a wsdl file directly instead of doing a wsdl2java...

Several comments :
1- is there any reason to have blank chars inserted after the path ? Seems that you already have a problem there. If possible, try to solve the problem at the source
2- the end of line char is usually CR (Carriage Return, aka ASCII char 13 = $0D = Control-D). But LF (Line Feed = 10 = $0A = control-A) is also used (platform dependent). In LV, you can use the "Concatenate strings" function to add/insert control chars (found in the String Control Palette). However, this will not solve your problem of unwanted added blank chars at the end of your string.
3- you can use the Trim white space.vi (in the "Additionnal string functions" sub-palette) to remove ALL the spaces in your string
4- you can build your own "end space remover" function. :
reverse the string, wire to a "Match pattern" function, use " +" (space + "+") to search for any number of spaces, reverse again the "after substring".
5- there is no point 5 :-)
You may find interesting description of ASCII chars here

How to invoke java class automatically at a fixed time everyday

How to invoke a java class automatically using Quartz scheduler or any other simplified way
I am trying to schedule a job in my web application and need to understand conceptually How to make it work using quartz . The job is scheduled to be executed at 4 pm daily. Am testing the same and It works well when i run it as standalone application manually.
How to configure it that when i start my aplication it should run at its own through quartz.
I am avoiding use of servlet init method and java timer though any alternatives there?
Thanks for your help.

I've not see quartz... are you in Windows, Solaris, Linux, or Mac?
Are you using JAR files or class files?
Windows: javaw myClass (I cannot remember right off if you have to have the .class on the end)
Windows: java -jar myJAR.jar
Solaris java -jar myJAR.jar
Linux java -jar myJAR.jar
Mac?

How to invoke Java class from post.POST.jsp

Hi All,
I am trying to invoke a simple java method from post.POST.jsp
I am getting below exception while doing it.
org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.jsp.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 32 in the jsp file: /apps/mywebsite/components/customFormAction/post.POST.jsp
The method test() is undefined for the type DatasourceUtil
29:
30:           ///
31:          com.day.test.datasource.DatasourceUtil dsUtil = new com.day.test.datasource.DatasourceUtilImpl();
32:          dsUtil.test();
33:           //dsUtil.validateLogin(request.getParameter("username"), request.getParameter("password"));
34:
35:           ////
It appears to resolve the class correctly. I could run the code, if I only comment dsUtil.test();. As soon as I uncomment, it gives above error.
In the Utill I have a simple void method which will print a simple text. My package structure is as follows.
any help will be great
Tx

1. In the interface [1] not the implementation[2] have u defined the method test?
2. If it is implemented, Change the bundle version in bnd file and make a new build. Then from felix console verify the latest version reflected in the bundles.
If 2 works & you are going to make lot of frequent changes then give the version as snapshot till it get stable.

How to invoke custom classes from logon PAR

Hi all,
Can someone tell me how I can invoke a java class that I have written on Click of a Submit button from the Help Page of the Login Screens. I have to customise this screen, changing the existing functionality.
Regards,
Ashwini.

Hi Ashwini,
On the onClick method of the Submit button refer the even handler method you have defined in you DynPage and in that event handler you can instantiate the required java class and call its functions.
ex:
in you JSP define:
<hbj:button
     id="submitButton"
     text="Submit"
     tooltip="Click to search the forum"
     onClick="onSubmit"
/>
in you DynPage define a event handler method called 'onSubmit(Event event)' and write you logic.
Cheers
Kiran

How to invoke a class at run-time for primitive data types?

Hi,
I am trying to invoke classes at run-time.
I am using Class.forName("className") for that where the "className" is also obtained at run-time .
The problem I am getting is when the "className" is "int" or "char" etc. the call to Class.forName("int") etc. fails giving ClassNotFound error. It works fine for "className" is "java.lang.String" or "java.lang.Integer" etc.
How can I correct this?
thanks in advance-
kg

Hi,
Thanks all for the valuable inputs.
I have created a hashtable of primitive data types in the form of "int" as key and "Integer.TYPE" as the object in that element of the hashtable.
Now there is another problem I am facing and that is of 'Casting at run-time'.
Problem is there when the Database type is 'NUMBER' which returns me a "java.lang.BigDecimal" when I do a ResultSet.getObject("XXX") for that whereas the method in the javabean expects an "int" type.
This causes "java.lang.IllegalArgumentException: argument type mismatch"
So I want to cast it at runtime. How can I do it?
Here is the code I am trying (which generates the above exception)
public static void setBeanField(Class pCls,Object pObj,String pMethodName ,Object pColumnValue,Class
pColumnTypeClass){
try{
if(pColumnValue!=null){
Class[] paramTypes = new Class[]{pColumnTypeClass};
Object[] args = new Object[]{pColumnValue};
Method meth = pCls.getMethod(pMethodName,paramTypes);
meth.invoke(pObj,args);
}catch(Exception e){
System.out.println("Exception in TestInrospection.setBeanField " + e);
thanks in advance-
kg

How to invoke another class filter in servlet

How can i do that? What code should i put in web.xml?
thank :)

Filters are invoked in the order as its filter-mappings appear in web.xml.

How to figure out class of method parameter given a VariableElement?

Background:
I have a class that extends AbstractElementVisitor6<String, VisitorContext>
In visitExecutable() I do something like this...
try {
    // processingMethod is a member variable of the visitor
    processingMethod = true;
    MyAnnotation foo = e.getAnnotation(MyAnnotation.class);
    if (foo != null) {
        List<? extends VariableElement> parameters = e.getParameters();
        for (Element enclosee : parameters) {
            enclosee.accept(this, context);
        // do other stuff
        return null;
    return null;
} finally {
    processingMethod = false;
}I then end up in visitVariable(VariableElement ve, P). Which is good.
However, I have been running in circles for at least a day now in the javadoc, trying to figure out how to get from a VariableElement to knowing what the class of the parameter is. I have figured out a way (correct or not) of knowing if it's a primitive type...
ve.asType() instanceof PrimitiveType But I'm stuck on figuring out what the class of the thing is. The closest thing I can see is if I can somehow turn the VariableElement into a TypeElement, I can use getQualifiedName(), but I'm haven't found that, and I'm not sure if that's the right answer either.
Here's the pseudocode of visitVariable...
public String visitVariable(VariableElement e, VisitorContext context) {
    if(processingMethod) {
        // if it's a primitive type - OK
        // do the right thing
        // else
        //   figure out what the class of e is   HELP!
        //   do the right thing
        return null;
}In summary...
How do I get the class of a method parameter from a VariableElement?
Thanks

When would this not be possible? Intersections types. See [JLS 3rd 4.9|http://java.sun.com/docs/books/jls/third_edition/html/typesValues.html#4.9] Specifically
"It is not possible to write an intersection type directly as part of a program; no syntax supports this."
Also, I'm curious about the string representation in the first place. I assume there's not direct handout of class objects because we're in the compiler and can't assume that a type is a valid "thing" yet? e.g. it may not have been compiled yetCorrect.
I was just thinking about how to represent the information, when it occurred to me that I probably ought to just reuse type mirrors and/or elements. Would you recommend this strategy? This is an interesting area of writing annotation processors. In order to apply any (what we call) extra-lingustic constraints and generate error messages when someone breaks the rules, you normally need the elements and types in order to make assertions about types being correct etc. I normally do this in the data collection phase, and don't collect any data for uses that are erroneous. I haven't tried doing the error checking after the collection phase.
When you are generating the source code, (after all the data is collected) all you need is CharSequences (normally Strings). In fact extracting those from elements and types at the point that is writing the source file can make the code more complex than it needs to be, so I prefer to just have everything in Strings at this point. It makes the code that is generating code a little easier to understand. I often build an inner class to hold all the strings (in fields or in collections as appropriate) which I have collected from each annotated element, so there is some structure there.
Are there any examples or other advice out there for doing this that you can point to?There are a few examples. Check out the [hickory project on java.net|https://hickory.dev.java.net/] You might find some useful tools there to assist writing your processor (such as prisms ) and [writing you unit tests|https://hickory.dev.java.net/nonav/apidocs/index.html?net/java/dev/hickory/testing/Compilation.html] . Hickory's unit tests include several examples of annotation processors, [this one|https://hickory.dev.java.net/source/browse/hickory/trunk/code/test/net/java/dev/hickory/incremental/ServiceProviderProcessor.java?rev=22&view=markup] illustrates the points I am making, and there are also some in code samples in the javadoc, for example [the same thing again |https://hickory.dev.java.net/nonav/apidocs/index.html?net/java/dev/hickory/incremental/StateSaver.html].

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->CallIntMethod( cls_JavaClassFile, mid_myJavaMethod, stringArray, myClassArray, myLong, intArray ); --- (1)
//jint returnValue = env->CallIntMethodA( cls_JavaClassFile, mid_myJavaMethod, ...........); --- (2)
//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.

Handler class is being called and is correctly configured.
I have tried thowing a JaxRPCException from my method call in the
Implementation class, but this simply fails.
My Handler class is as follows:
public class ServerHandler extends GenericHandler {
public ServerHandler() {
public boolean handleResponse(MessageContext context) {
System.out.println("In the response method:");
return true;
public void init(HandlerInfo hi) {
System.out.println("In the init method::");
public boolean handleRequest(MessageContext context) {
System.out.println("In the Handle request method:");
return true;
public boolean handleFault(MessageContext context) {
System.out.println("In the Handle fault method:");
//Want to do stuff like create a Soap Fault
return true;
public void destroy() { }
public QName[] getHeaders() { return null; }
Any Help would be much appreciated
Thanks

Basically u need to throw a SOAPFaultException in the request/response methods ....Its fairly well documented in the JAX-RPC Specification

How to call Java class from Forms 6i?

Hi friends,
I need to call a Java class from my Forms 6i application.
(It runs under WIndows XP. It's a client/server application and I have only the client and the Form builder installed on my PC)
I don't know almost anything about Java's world so your help would be very useful for me.
Could you tell me exactly what i have to do?
I've read in metalink several Notes, but they supposed that the Java architecture is already installed in the computer.... I only have the default installation of Developer 6i... so I would need to know:
- How to install/configure the neccesary to execute Java classes without problem
- How to invoke the .class from Forms 6i.
Thanks a lot
Jose.

And also this one:
Problem Description
Installed Forms 6i Rel 2 on a MS Windows machine. When trying to Import the Java
Classes getting the errors
PDE-UJI0001 Failed to create the JVM
Solution Description
You need to to install JDK 1.2.2 to run the Java Importer. And set the PATH's
and classpath's correctly.
Explanation
1. Download and install the JDK 1.2.2.
Possibly available at: http://java.sun.com/products/archive/
2. Assuming the JDK 1.2.2 is installed in c:\jdk1.2.2 directory and the JRE in
C:\PROGRA~1\JAVASOFT\JRE\1.2 directory; ORACLE_HOME=C:\Dev6iR2.
Set the PATH to
set PATH=c:\jdk1.2.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin\classic;%PATH%
( If you are using ias9i then the JDK 1.2.2 comes with the ias installtion ,
in this case please set the PATH to
D:\ias9i\Apache\jdk\bin;D:\ias9i\Apache\jdk\jre\bin;D:\ias9i\Apache\jdk\jre\bin\classic;%PATH% )
3. Set the CLASSPATH to set CLASSPATH=%CLASSPATH%;C:\Dev6iR2\TOOLS\COMMON60\JAVA\IMPORTER.JAR;.
(If you do not set the CLASSPATH correctly you will get the error
PDE-UJI002 Unable to find the required java importer classes)
4. Now run the Forms Builder by using the command.
C:\Dev6iR2\bin\ifbld60.exe
Now the Java Importer Should Run fine.

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?
