How to call a Java class from another java class ??
Hi ..... can somebody plz tell me
How to call a Java Class from another Java Class assuming both in the same Package??
I want to call the entire Java Class (not any specific method only........I want all the functionalities of that class)
Please provide me some slotuions!!
Waiting for some fast replies!!
Regards
Smita MohantyHi Smita,
you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
e.g.
you have developed A.java and B.java, both are in same package.
in implementaion of B.java
class B
A obj = new A();
//to access A's methods
A.method();
// to access A's variable
//either
A.variable= value.
//or
A.setvariable() or A.getvariable() -
How to call a java program in javafx class(Urgent) and even vice versa
Hi all,
Here I have two questions:
1)
Please let me know how to call a javafx in java program...
I tried with the following code but it is not working..
The below is the java program in which I made a call to the Fx program.
FxMainLauncher.java
import net.java.javafx.FXShell;
public class FxMainLauncher {
public static void main(String[] args) throws Exception {
FXShell.main(new String[] {"HelloWorld.fx"});
2) How to call a java program in javafx class
Here is my javafx program
import check.*;
import javafx.ui.*
var instance = new MyJava();
//visible:true
System.out.println("Number is: {instance}");
Here is my java program
public class MyJava {
public static void main(String args[])
System.out.println("JAVAFX TO JAVA");
Even this is not working please let me know ASAP
Thanks in advance,
V.SrilakshmiGOT IT !!!
I had to change the name of the method in .h file generated by javah command. On doing
javac -d ../../classes HelloWorld.java
go to the ../../classes directory (where you have the class file) and do
javah HelloWorld
I got a HelloWorld.h file in which I had
JNIEXPORT void JNICALL Java_HelloWorld_display(JNIEnv *, jobject);
I added the package name too:
JNIEXPORT void JNICALL Java_GUI_HelloWorld_display(JNIEnv *, jobject);
The HelloWorldImp.c file should have the same name (ie with package) and be in the same directory(ie ../../classes)
compile and build the shared library to get "libhello.so" file
gcc -c -fPIC -I/usr/lib/j2sdk1.3/include -I/usr/lib/j2sdk1.3/include/linux HelloWorldImp.c
gives .o file
gcc -shared -o libhello.so HelloWorldImp.o
gives .so file
then run java with the command in my first message. It works.
Thanks for the reply "thedracle". -

How to: Calling a java class from asp?
Hello all i have a problem to call a Java class from a asp
Here what I do:
[JavaSays.java]
package JavaCom;
public class JavaSays
public String Hello()
return "Hello world" ;
then
javareg /register /class:JavaCom.JavaSays /progid:JavaCom.JavaSays
md c:\winnt\Java\TrustLib\JavaCom
copy JavaSays.class c:\winnt\Java\TrustLib\JavaCom
--Asp
--TestJavaCom.asp
<html>
<body>
<h1>Simple Test</h1>
<% Set ObjPrueba = Server.CreateObject("JavaCom.JavaSays") %>
<%= ObjPrueba.SimpleFn(5) %>
<hr>
</body>
</html>
when i try to run my asp
it tell me that:
Error type : Server Objetc, ASP 0177 (0x80040111)
ClassFactory can not find the class
any idea???
thanks.I think the OP wants to use a class file as a COM object. I've never done that, but this URL:
http://support.microsoft.com/default.aspx?scid=KB;EN-US;q167941&
seems to indicate that you should have placed the class file into the c:\winnt\Java\TrustLib\ sub directory before you ran the JAvaReg bat file - I would re-run JavaReg and bounce IIS and associated services and see if that works out.
Good Luck

Is there a tutorial on - how to call static java methods
I have defined external JAVA resource using a .jar file and have successfully catalogged the same. Now I need to pass variables to a static method in a class and also get the return variable mapped into a BPM variable.
Can someone share sample Java Invokation code, how to call methods in a class, how to instantiate a singleton or reference an existing instance of singleton class.
Any sample code or sample projects will be useful.
Also can I se ethe java system.out.println output in BPM Logviewer
ArvindHi Arvind,
Sure you've done this, but the first step is to catalog the Jar file. Before an Oracle BPM project can use the Java component, the appropriate Java JAR files must be added to the project.
Add the Jar File(s) to the External Resources:
1. Right-click the External Resources item in the Project Navigator tab
2. From the pop-up menu, select New External Resource.
3. Name this new Java resource "MyNewJavaComponents" and ensure its type is Java Class Library.
4. Add the Java jar file(s)
Catalog and Expose the Java Components:
5. Add a new module in the Catalog called "IntegrationComponents".
6. Generate a Java integration component by right-clicking the IntegrationComponents module and select "Catalogue Component" -> "Java".
7. Using the Java configuration you just created called MyNewJavaComponents, click the Next button to automatically introspect the Java libraries.
8. Select the class where your method(s) are located and click the Next -> Finish buttons to have Oracle BPM generate the integration component for you.
9. If you expand the newly exposed Java component, you can see a method has been created for each public method (attributes would also be automatically created if this class had any public attributes). If you've included the appropriate BeanInfo class in the JAR, you'll note that the method parameters are appropriately named.
How to Invoke Public Java methods Exposed in the Catalog:
10. Open the method editor for an automatic activity in the process (or any BPM Object method with its "Server Side" property set to "Yes").
11. Drag one of the Java methods you just exposed inside your IntegrationComponents module into the automatic activity's method. Once you drag it in, here's what you might see if you're using the Java syntax in Oracle BPM's method editor:
(PdfGenerator).generate(outputFilename : "", contents : { }, logoImageURL : null, signatureImageURL : null);
Assuming you have "outputFilename", "sampleContent", "logoURL" and "signatureURL" variables already created in your process, change the method you just dragged in to:
IntegrationComponents.Pdfservice.PdfGenerator.generate(outputFilename : outputFilename, contents : sampleContent,
logoImageURL : logoURL, signatureImageURL : signatureURL);
Hope this helps,

How to call a java method in a Stored procedure
Hi.,
I was trying to call a method in a stored procedure
This was my procedure
CREATE OR REPLACE PROCEDURE proc_copy_file(sr_file VARCHAR2,dt_file VARCHAR2)
AS LANGUAGE JAVA
NAME 'FileCopy.copyfile(String,String)'; // calling a java method
/ this was my java method
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "FileCopy" as
import java.io.File;
import java.io.IOException;
import java.io.FileReader;
import java.io.FileWriter;
import javax.imageio.stream.FileImageInputStream;
import javax.imageio.stream.FileImageOutputStream;
import java.security.AccessControlException;
public class FileCopy {
// Define variable(s).
private static int c;
private static File file1,file2;
private static FileReader inTextFile;
private static FileWriter outTextFile;
private static FileImageInputStream inImageFile;
private static FileImageOutputStream outImageFile;
// Define copyText() method.
public static void copyfile(String fromFile,String toFile) throws AccessControlException
// Create files from canonical file names.
file1 = new File(fromFile);
file2 = new File(toFile);
// Copy file(s).
try
// Define and initialize FileReader(s).
inTextFile = new FileReader(file1);
outTextFile = new FileWriter(file2);
// Read character-by-character.
while ((c = inTextFile.read()) != -1) {
outTextFile.write(c); }
// Close Stream(s).
inTextFile.close();
outTextFile.close(); }
catch (IOException e) {
System.out.println ("-------"); }
// return 1;
public static void main(String[] args){
switch(args.length){
case 0: System.out.println("File has not mentioned.");
System.exit(0);
case 1: System.out.println("Destination file has not mentioned.");
System.exit(0);
case 2: copyfile(args[0],args[1]);
System.exit(0);
default : System.out.println("Multiple files are not allow.");
System.exit(0);
};while i am executing this method i m getting error as
ORA-29531: NO METHOD COPYFILE IN CLASS FILECOPY
ORA-06512: AT "RMVER721.PROC_COPY_FILE", LINE 1could anyone help meLooks like it is a matter of not quite the same namespace for String object.
I can get it to work by the java source containing:
public static void copyfile(java.lang.String fromFile,java.lang.String toFile) throws AccessControlExceptionAnd the PL/SQL source:
NAME 'FileCopy.copyfile(java.lang.String,java.lang.String)'; // calling a java methodSeems like when you just use "String", then the namespace resolving in the java source is not the same as the namespace resolving in the PL/SQL?
Addendum:
You do not need to put java.lang.String in the java source, String will do (java.lang is by default "imported"?)
But in the PL/SQL source java.lang namespace prefix is needed - java.lang is not "imported" here.

How to call function module/ class method of another system.
Suppose now i am working in System A. And i need to check the system Status of System B, System C, System D....
my design is to provide an interface. and each system realize the interface individually.now my question is how cani call the interface, because they are in different systems.
of course i know about the host name, port and logon information over these systems.
who can give my some suggestions or other solutions.
thanks in advance.
Johnney.Hello,
If u want to call a FM of the other system then that FM should be a RFC enable on one.
<b>CALL FUNCTION func DESTINATION dest.</b>
Effect
Executes the function module from an external source (as a Remote Function Call or RFC); dest can be a literal or a variable.
Depending on the specified destination, the function module is executed in another R/3 or R/2 System. Externally callable function modules must be flagged as such in the Function Builder (of the target system).
Since each destination defines its own program context, further calls to the same or different function modules with the same destination can access the local memory (global data) of these function modules.
To maintain existing destinations, choose Tools -> Administration, Administration -> Network -> RFC destinations
Note
Under certain circumstances, an RFC may trigger a database commit. For this reason, RFCs must not be used between pairs of SQL statements that open and close a database cursor (such as SELECT... ENDSELECT).

Requesting an overview of how to call a Java program from EBS.
Hi,
I am an experienced Java developer in the middle of an implementation of EBS 12g. I am very new to EBS and I'm not sure where to start on this. I need to provide users the ability to call a Java program that prints a report from EBS. I would be grateful if somebody would outline the general approach that should be used. Links to documentation/tutorials are appreciated also.
Thanks,

How to call a Java method in a C consoleapplication?
I have to call a void method of a javaclass using a c consoleapplication. No argument are passed to it.
I can't make an object of that class..
This is my implementation in c (using JNI):
void update(void)
classn = "<name>";
cls = (*env) ->FindClass(env, classn );
if (cls == 0)
printf(" Can't find class %s\n", classn );
mid =
(*env)->GetMethodID(env, cls, "<methodname>", "()V");
(*env)->CallVoidMethod(obj, env ,m id);
This goes wrong...
The problem is that I have no jobject (obj) of the class, because I don't want one...I don't need one. How can I call that void method without an object and only using the classname..??You have to make the java method a static method, and use CallStaticVoidMethod.
"static" means that the method belongs to the class, and not an object of that class.
