Implicit call to java method

Hi,
I have a class composed by some methods, I want to find a way on for implicitly call a method in start and end of every method of my class without coding it.
example
this is my class :
public class MyClass {
public void a(){
public void b(){
call :
MyClass class = new MyClass();
class.a();
i want that when i do like below the execution will be like :
implicitCall();
a();
implicitCall();
is that possible?
Do you have any idea, on how to do that.
Thanks in advance

Using wildcard expressions, package names etc etc, there is definitely a way to do what the OP is trying to do with Spring AOP. Section 6.2.3.4 of http://static.springsource.org/spring/docs/2.5.x/reference/aop.html has the information. Much easier to do than byte code instrumentation and much cleaner than implicitly calling start/end methods.

How to call a C function calling a Java Method from another C function ?

Hi everyone,
I'm just starting to learn JNI and my problem is that I don't know if it is possible to call a C function calling a Java Method (or doing anything else with JNI) from another C function.
In fact, after receiving datas in a socket made by a C function, I would like to create a class instance (and I don't know how to do it too ; ) ) and init this instance with the strings I received in the socket.
Is all that possible ?
Thank you very much for your help !

Hard to understand the question, but by most interpretations the answer is going to be yes.
You do of course understand that JNI is the "API" that sits between Java and C and that every call between the two must go through that. You can't call it directly.

Looks 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.

Rhino calling overloaded Java methods with Array parameters

Has anyone had any problems writing JavaScript code that calls overloaded Java methods?
I have two Java defined methods that differ in the arguments, one takes a string the other takes an array of strings. The problem is calling Java methods within the JavaScript always calls the method with the String argument...
/* Java Code Here */
public void function(String s) { /* Function A */ }
public void function(String[] sa) { /* Function B */ }
/* JavaScript Code Here */
param = java.lang.reflect.Array.newInstance(java.lang.String, 2);
param[0] = "test";
param[1] = "test2";
stringParam = "test3";
/* Both function calls below end up calling the Function A from above */
function(param);
function(stringParam);PS...in case you're not familiar with Rhino,
It is a mozilla package that embeds a JavaScript interpreter within a Java application...

haha...I can't even find my other thread :(
Sorry about the double post...I'll go look for my other thread now

Next time please paste your code between [code] tags with the code button just above the edit message area.
To answer your question, you wrote the wrong method signature. It should be:jmethodID mmid = env->GetMethodID(cls, "recibeBuffer", "()V");Regards

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.

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
Arvind

Hi 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,
Dan

Cant Call Stored Java Method Oracle 8I

Order of arguments while calling a Java method from C

Hi
are there any rules to order the transferred arguments ?
I wanted to transfer a native window event from C to Java and if the called
java method is declared like this: (int, long, int) (IJI)V
public static void nativeMouseButtonDownCallback(int wParam, long lParam, int which)
the value of 'which' is not correct (always the same independent from what I set it to in the C function)
If I declare the java method like this: (int, int, long) (IIJ)V
public static void nativeMouseButtonDownCallback(int which, int wParam, long lParam)
everything is fine.
Any information appreciated !
Bye Mark

Thanks for your reply !
Initially I also thought that the set of the value could be wrong and so
I used a printf statement in C to monitor the transferred value.
And still: the value I put in was different from what I got in java.
After this I put in simple numbers like 1,2,3 and in java I still got
the same wrong value.(guess max signed int 21474836..)
I really replaced the dll and class files and restarted the IDE.
The problem got solved by changing the order of the long an int.
Bye Mark

How to call a java method so I can pass a file into the method

I want to pass a file into a java method method from the main method. Can anyone give me some help as to how I pass the file into the method - do I pass the file name ? are there any special points I need to put in the methods signature etc ?
FileReader file = new FileReader("Scores");
BufferedReader infile = new BufferedReader(file);
Where am I supposed to put the above text - in the main method or the one I want to pass the file into to?
Thanks

It's a matter of personal preference really. I would encapsulate all of the file-parsing logic in a separate class that implements an interface so that if in the future you want to start taking the integers from another source, e.g. a db, you wouldn't need to drastically alter your main application code. Probably something like this, (with an assumption that the numbers are delimited by a comma and a realisation that my file-handling routine sucks):
public class MyApp{
public static void main(String[] args){
IntegerGather g = new FileIntegerGatherer();
Integer[] result = g.getIntegers(args[0]);
public interface IntegerGatherer{
public Integer[] getIntegers(String location);
import java.io.*;
public class FileIntegerGatherer implements IntegerGatherer{
public Integer[] getIntegers(String location){
FileInputStream fs=null;
try{
File f = new File(location);
fs = new FileInputStream(f);
byte[] in = new byte[1024];
StringBuffer sb = new StringBuffer();
while((fs.read(in))!=-1){
sb.append(new String(in));
StringTokenizer st = new StringTokenizer(sb.toString(),",");
Integer[] result = new Integer[st.countTokens()];
int count = 0;
while(st.hasMoreTokens()){
result[count]=Integer.valueOf(st.nextToken());
count++;
catch(IOException e){
//something sensible here
finally{
if(fs!=null){
try{
fs.close();
catch(IOException f){
return result;
Once compiled you could invoke it as java MyApp c:\myInts.txt

How to call a java method asynchronously

Hello All,
I am using a managed bean for calling a method to send email after records are commited, the email is sent through pl sql procedure in oracle database.
But this procedure takes some time to send the email , due to which the next page navigation becomes slow. I do not want to wait for this procedure to be completed, I want to call this method asynchrounosly. Please advice me .
Thanks in advance.

I would not recommend using threads for all possible use cases, but there are some long running use cases which can't run in synchronous mode without putting the user to sleep...
We have some cases, e.g. generating monthly reports, which take up to 5 hours to compile. I don't like to put all the work into the db because I'll have some legacy systems to work with, so I have to use java anyway.
There are some lessons to learn, but I did not find a show stopper for my job scheduling (using threads).

How to call a Java method n map the output of that method to a table in ODI

Hi,
I'm new to ODI. I've written an interface which joins two tables( in source ) to a file (in target). Now i have to apply a method(java call) on each element of a column in the target. Now my questions are :
1. All that i know is to use Procedure using either Jython or Java BeanShell. Can you give some sample commands to achieve such functionality?
2. Where should i actually apply this procedure? Is it possible to apply this procedure within the Interface during mapping (so that i can directly map the result to the output file)?
Thanks in advance :)

Suppose the java code is like below
import java.io.*;
public class FileWrite
public void writeFile()
FileOutputStream fos;
DataOutputStream dos;
try {
File file= new File("C:\\MyFile.txt");
fos = new FileOutputStream(file);
dos=new DataOutputStream(fos);
dos.writeInt(2333);
dos.writeChars("Hello World");
} catch (IOException e) {
e.printStackTrace();
Next we compile the .java class from the command line and create the jar file.
Then copy and paste the .jar archive to the ODI drivers folder. Next we restart the ODI agent.
Now call methods in this class from either Jython
import FileWrite
fw=FileWrite()
fw.writeFile()
or from the Java BeanShell
import FileWrite;
FileWrite fw = new FileWrite();
fw.writeFile();
2. Where should i actually apply this procedure? Is it possible to apply this procedure within the Interface during mapping (so that i can directly map the result to the output file)?If your method is inside your jar file returning one value then store into one variable.Then use this variable in your interface or procedure wherever you want.
As GURU told we cannot use procedure inside interface mapping.
Thanks

Is it possible to call a java method from servlet

Hi All,
I am trying to import a java class to my servlet and call a method of that class, is this possible. I am getting an error while importing the class.
I am using tomcat, have put my class files in th path
\WEB-INF\classes\com\kiran
My java goes like this
package com.kiran;
import java.sql.*;
import javax.sql.*;
public class DbCon
{ Connection con=null;
public Connection getCon()
-----return con;
catch(Exception e){ return con; }
and my aim is to call getCon() from my servlet. which is as follows
package com.kiran;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import com.kiran.DbCon;
public class check extends HttpServlet
DbCon db;
i am not able to compile my servlet, err is --> cannot find symbol DbCon..
How can i import the class, do i require any entries in web.xml ?
expecting your advice..
Thanks in advance
Best Regards,
Kiran

Ok, first off, if you are testing in tomcat (and as you said you are placing the class files in the path), you already compiled this classes, right? Otherwise I don't see how you placed your classes in /WEB-INF/classes/. Note that you will need two class files (based on your code. If not, then I'm missing part of the question. Typically, your IDE will help you with this problem a lot. The only thing that seems confusing is the catch (Exception e) statement which needs to be as part of a method (I assume this is a typo on your part).
If your problem is at runtime, don't forget to configure your web.xml to see your servlet.
