Calling C++ method from Java program on Linux

I'm trying to get set up to call a C++ method from a Java app on a SUSE Linux box. I follow the steps of the "Hello World" baby example in Beth Stearns's tutorial, "Integrating Native Code and Java Programs", but I get the following error message:
Exception in thread "main" java.lang.UnsatisfiedLinkError: /users/dmizell/testIF/libhello.so: /users/dmizell/testIF/libhello.so: invalid ELF header (Possible cause: endianness mismatch)

at java.lang.System.loadLibrary(System.java:1028)
at HelloWorld.<clinit>(HW.java:7)
at Main.main(Main.java:5)
Any idea what I might be doing wrong?
thanks

Your library is compiled in a way which is incompatible with the VM you are using.
Note that there is a JNI forum.

How to Call C++ Method from Java

I need to call C++ method from Java.
I have gone through the JNI tuorial , but was not able to pin point things.
I read that :
You have to write JNI c functions which then call your C++ member functions.You need to write a JNI function which will call new on your C++ class.
Now i have java class :
Java Code JavaClass.java ---->
class JavaClass{
public native void nativeMethod();
    static
        System.loadLibrary("NativeCppCode");
     private void callCppMethod()
          //call C++ method
                JavaClass jvc = new JavaClass();
                jvc.nativeMethod()
}Cpp Code:
NativeCppCode.h---->
class NativeCppCode
public:
    getValue();
    setValue();
private:
   int a;
JNIEXPORT void JNICALL Java_JavaClass_nativeMethod(JNIEnv *env
               ,jobject obj);NativeCppCode.C---->
NativeCppCode::getValue()
   return a;
NativeCppCode::setValue()
   a = 1;
JNIEXPORT void JNICALL Java_JavaClass_nativeMethod(JNIEnv *env
               ,jobject obj)
NativeCppCode* nativeInstabce = new NativeCppCode();
NativeCppCode.setValue();
}Is this the correct way to do it.
Any suggestion would be a great help to me

tryit wrote:
I need to call C++ method from Java.Not possible.
JNI uses C methods.
Is this the correct way to do it.Same way you would do it in any C/C++ method (not java)
       MyClass* p = ....
       p->doit();
Common idiom for the pointer in the above is to pass it back and forth to your java code as a java long. You cast it it and from your class pointer. Provide an explicit java method to free it when done. Besides providing the explicit method also implement a finalizer to free it as well (however that is a fail safe and should not be relied upon.)

How to Call .XDO file From Java Program

Hi,
I have developed a report in using BI Publisher version 10.1.3.
I created the report and it only created XDO files. If I want to call XDO file from Java program how I can do that.
What are the APIs available to do that.
Thanks
-Ashutosh

Hi,
the JavaAPI didn't work with the xdo-Files. But you can create a proxy stub for the Web Service API of BI Publisher which uses the xdo's in the repository.

It's an extremely important skill to learn how to search the web. Not only will it increase your research and development talents, it will also save you from asking questions that have already been answered numerous times before. By doing a little research before you ask a question, you'll show that you're willing to work and learn without needing to have your hand held the entire time; a quality that is seemingly rare but much appreciated by the volunteers who are willing to help you.
If you've done the research, found nothing useful, and decide to post your question, it's a great idea to tell us that you've already searched (and what methodologies you used to do your research). That way, we don't refer you back to something you've already seen.

Calling c method from java

Hi,
I am new to JNI. I want to call a C function from java, where my C function name is
UINT8 abc(UINT8 feature, UINT8* in_value, UINT32 serialNo, UINT8 * out_value)
where,
typedef unsigned char UINT8;
typedef unsigned int UINT32;
My question is what should be the prototype defination in java and what has to be changed in C code to make it work?

After adding the native keyword to your Java method, compile with javac and run javah on the class name. For example:
package my.stuff;
public class MyClass
   public native void myMethod(char param1, int param2);
}javac ./my/stuff/MyClass.java
javah my.stuff.MyClass
This generates my_stuff_MyClass.h, which has the function prototype for your method. Inside the implementation of the function, you can call your C function.
Here is the contents for my_stuff_MyClass.h:
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class my_stuff_MyClass */
#ifndef _Included_my_stuff_MyClass
#define _Included_my_stuff_MyClass
#ifdef __cplusplus
extern "C" {
#endif
* Class:     my_stuff_MyClass
* Method:    myMethod
* Signature: (CI)V
JNIEXPORT void JNICALL Java_my_stuff_MyClass_myMethod
(JNIEnv *, jobject, jchar, jint);
#ifdef __cplusplus
#endif
#endif

Calling batch file from java Program

I have made the java program in which i have called the batch file.But the problem is this that when i call batch file locally it executes normally but when i try to execute batcvh file from remote machine it doesn't runrather it gives Runtime IO execption.Error123.Can anyone provide me the solution for this?

Not without a lot more information. Like for example how you are trying to execute this remote batch file, the code you are using to do that, what kind of server you have no the remote machine to let you remotely execute code, and so on.

Calling FND_VAULT.get from Java program

Hi,
I am creating a Java Concurrent Program in EBS and from my Java program I want to invoke "FND_VAULT.get" procedure.
Can someone please guide me on how to do that.
Thanks

Actually I am having 4 Shell Scripts which I want to
call at a time.
1)run_graph.sh
2)run_report.sh
3)web_report.sh
4)mktg_report.sh
Now I want to call all the four from a Java Program at
the same timeWell... if you truly want to run them at the same time, you'll need to look into multithreading.
What I suspect you really want is to run them in the above order within the same Java program.
String pathToScripts = "/etc/path/to/your/scripts/";
String[] scripts = {"run_graph.sh", "run_report.sh", "web_report.sh", "mktg_report.sh"};
Process p = null;
for (int i=0; i<scripts.length; i++){
p = Runtime.getRuntime().exec(pathToScripts + scripts);
p.waitFor();
System.out.println(scripts[i] + " completed with exit code " + p.exitValue());
If you want to capture output or send input for the above processes, see the java.lang.Process and java.lang.Runtime API docs:
http://java.sun.com/j2se/1.3/docs/api/java/lang/Runtime.html
http://java.sun.com/j2se/1.3/docs/api/java/lang/Process.html
Hope this helps,

How to call stored procedures from java program?

I have tried to run a program that calls a stored procedure on MySQL
server version 5.0.17 by using connector/j 5.0, but it always fails on the
statement: con.preparecall() ,
have looked on the internet and found out that people can all mysql
stored procedure all right in their programs, really dont know what's
wrong with this small peiece of code:
import java.sql.*;
public class TestDB {
      // procedure being called is:
     CREATE PROCEDURE `dbsaystorm`.`getsite` ()
     BEGIN
        select name from tblsite;
     END
     public static void main(String[] args) {
          try {
              //Class.forName("org.gjt.mm.mysql.Driver");
              Class.forName("com.mysql.jdbc.Driver");
              Connection con = DriverManager.getConnection("jdbc:mysql://localhost/dbname",
                        "user", "pwd");
       * executing SQL statement here gives perfect correct results:
        // PreparedStatement ps = con.prepareStatement("select name from tblsite");
        // ResultSet rs =ps.executeQuery();
              // but in stored procedure way...
              //it fails here on this prepare call statement:
              CallableStatement proc = con.prepareCall("call getsite()");
              ResultSet rs =proc.executeQuery();
              if (rs == null) return;
              while (rs.next()){
                  System.out.println("site name is: "+ rs.getString(1));
              rs.close();
          } catch (SQLException e) {e.printStackTrace();}
           catch (Exception e) {e.printStackTrace();}
}it always gives this exception:
java.lang.NullPointerException
     at com.mysql.jdbc.StringUtils.indexOfIgnoreCaseRespectQuotes(StringUtils.java:959)
     at com.mysql.jdbc.DatabaseMetaData.getCallStmtParameterTypes(DatabaseMetaData.java:1280)

     at saystorm.server.data.database.TestDB.main(TestDB.java:29)
where have I gone wrong?
when I commented out the statement that makes the procedure call and call preparedstatement to execute SQL select statement, it gave perfectly correct result.
it looks like there is no problem with java prog accessing MYSQL server database, but the it seems that it's just java can't call stored procedure stored on the mysql server version 5.
can it or can't it? if it can, how is that accomplished?

It is a bug in the driver because it shouldn't be
returning that exception (null pointer) even if you
are doing something wrong.
Are you using the latest version of the driver?
The stored procedure runs when you run it from the
gui/command line using a MySQL tool - correct?
As suggested you should be using the brackets. What
is the data type of the 'name' field?
You could try returning another value like one of the
following
select 1, name from tblsite;
select name, 1 from tblsite;
That might get around the bug
Additionally try just the following...
select 'test' from tblsite;yes, the driver used is in connector/j 5.0--the lastest one, and the
procedure can run correctedly at either command line or GUI mode
with no problem whatsoever, the returned data type is string type,
I have not got the chance to test it again with those values you
suggested, as I have abandoned the laptop I used to write that code
initately. There have been some other really weird cases happened on
that computer. I guess that must be something wrong with the JVM
installed on it, it was upgraded from jre5.0.04 to 06, and to 09.
something within hte JVM must have been messed up(the only reasonable
explanation). Because the same code runs correctly on my new laptop,
using the same environment: jvm 5.0_09, mysql 5.0.18, connector/J 5.0.
that old laptop really was a nightmare.

You can create two different files which has sqlldr command defined....

2. loader.bat
and in the depending on the OS execute one...
         String command = "";
         if(System.getProperty("os.name").equals("Windows 2000")){
                //if os is windows 2000 then execute bat file
                 command = <<bat file path>>
          }else{
                  command = <<shell path>>
          Runtime rt = Runtime.getRuntime();

Calling oracle SQL Loader from java program

Hi,
I want to insert data into oracle tables from a text files containing fixed length fields. I am using SQLLoader to achieve this. The requirement is to call the SQLLoader within the java program.
Does anyone know how to call SQL Loader from java program?
Thanks,
Varsha

Simply "exec" the sqlldr program with the parameters you need to pass to it.
Runtime.exec (........)
Try to pass all parameters needed including the username and password, and use the option "silent" to avoid output, and the option "log" to have a log file of the modifications that sqlldr has done to the database.
