Session retention with Java WD and OBN navigation

Hi everybody,
We have a Java WD application integrated into Business byDesign Portal. From this application we start OBN navigation in the same window. OBN navigation always starts a new session with ABAP back-end. Is it possible to retain the same back-end session between Java WD and launched OBN navigation? What should be done for it?
Thank you for yor help and kind regards,
Helen

is it something that you want to debug at runtime and find out those values?

Set role with Java JPA and NativeSQL

Hi,
using 10g setting roles with Java JPA and NativeSQL works fine. After the upgrade to 11g the same commands will not work.
Ars ther any significant changes to set roles in 11g?

Ars ther any significant changes to set roles in 11g?When I eval'd 11g, I did not notice any changes in setting my roles. I did notice a significant difference in Java. I cannot remember the JDK version change from 10g to 11g. We ended up settling back to 10g for other reasons.

Below is the executable code generated using NetBeans which is enough to generate the error message. Sometimes you can get the error message just by running the program. Sometimes the error will occur when you go into the Menu and click on Item.

Problem with Java 5 and Oracle 10g JDBC driver

Hi All,
Currently we upgrade our web application to Java 5 and Oracle 10.2 JDBC driver. And we encountered a bug, when the user entered the information through UI and data didn't store into database (Oracle 9i). The problem is that this bug is not happend so often maybe once a day and this did not happen before we upgraded to Java 5 and Oracle 10.2 JDBC driver. Does anyone encounter the same problem ? Is this Java 5 problem or Oracle JDBC driver problem ?
Thanks,

sounds like a database problem...
Are you using a driver version that's supported for your database engine?
What else did you change? We once ran into a major bug in our application that had for 5 years been masked by performance problems in our hardware and infrastructure.
Once those were resolved the bug showed itself and caused tens of thousands of records to be erroneously inserted into our database every day.
It's certainly NOT a problem with your JVM (if it's a decent one, like the Sun implementation).
So it's either your database, your driver, your network (dropping packets???), or your application.
The upgrade may just have exposed something that was already there.

Problem with java, ASCII and Linux

Hi Friends,
I has a Linux RedHat 9.0 with a jre1.5.0_04 (rpm package of Sun).
I has a problem with ASCII , for example :
import java.io.*;
public class HolaMundo
public static void main (String[] args)
System.out.println("Hol� M�ndo");
this programs runs ok on my windows jdk so it prints "Hol� M�ndo", but when i run the same HolaMundo.class program on my linux redhat it prints "Hol�� M��ndo"
I think the problem is with the ASCII table that uses the linux version of jre, but i dont know how to solve this problem. I need a Spanish-European ASCII table on my application but i think it is working with a US-ASCII table.
Then i has installed a kaffe 1.0 (rpm) java machie on this linux and this solve the problem but i has another problems of compatibility with this old version of java kaffe.
Do you know whats happening?
Thanks in advance.

The problem doesn't have to do anything with Java or Linux as far as i can see. It's more likely a problem with Windows XP and IE. Be assured that normally downloading the Linux JDK in windows is not a problem.

Help with Java JNI and C++

Hi everyone! I have a problem with Hello World example. I wrote java code in Visual Age 4.0:
<HelloGinja.java>
package jnitest;
public class HelloGinja {
 static {
 System.load("c://c++//hellotest//release//hellotest.dll");
 * HelloGinja constructor comment.
 public HelloGinja() {
 super();
 public native void displayHelloGinja();
 public static void main (String args[]) {
 System.out.println("Calling displayHelloGinja...\n");
 new HelloGinja().displayHelloGinja();
 System.out.println("Finished displayHelloGinja...\n");
}I made header file from command line:
javah -jni jnitest.HelloGinja
I wrote C++ code in Visual Studio 6.0:
<hellotest.cpp>
#include "stdafx.h"
#include "hellotest.h"
#include <jni.h>
#include "jnitest_HelloGinja.h"
#include <stdio.h>
BOOL APIENTRY DllMain( HANDLE hModule,
 DWORD ul_reason_for_call,
 LPVOID lpReserved
 switch (ul_reason_for_call)
 case DLL_PROCESS_ATTACH:
 case DLL_THREAD_ATTACH:
 case DLL_THREAD_DETACH:
 case DLL_PROCESS_DETACH:
 break;
 return TRUE;
// This is an example of an exported variable
HELLOTEST_API int nHellotest=0;
// This is an example of an exported function.
HELLOTEST_API int fnHellotest(void)
 return 42;
// This is the constructor of a class that has been exported.
// see hellotest.h for the class definition
CHellotest::CHellotest()
 return;
extern "C" {
 JNIEXPORT void JNICALL Java_jnitest_HelloGinja_displayHelloGinja(JNIEnv *env, jobject obj)
 printf("\nHello Ginja Glisic!\n");
 return;
}What is the problem? I compile program well but when I run it from VAJ I am getting:
Calling displayHelloGinja...
Finished displayHelloGinja...
It seems like it does not call native method at all. I exported file out from VAJ and run it from command line.I got:
Calling displayHelloGinja...
Hello Ginja Glisic!
Finished displayHelloGinja...
Everything is ok.It works. why then it won't work in VAJ?
Can anyone have idea? I will be very thankfull for any help or advice.

Ok, I solved my problem. I returned string from native method to java code and I got it. The point is native method is being called but I couldn't see it's output from VAJ.
Does anyone know any good tutorial about VAJ? If does, please post it .

Audio capture delayed with Java Sound and JWS

Hi.
I am experiencing quite a strange problem with Java Sound in my Java Web Start application. I am acquiring sound from the microphone through Java Sound, using a code which looks like this:
==============================
AudioFormat audioFormat = new AudioFormat(11025, 8, 1, true, false);
// Get a TargetDataLine from the appropriate mixer
DataLine.Info dataLineInfo = new DataLine.Info(TargetDataLine.class, audioFormat);
TargetDataLine targetDataLine = (TargetDataLine) AudioSystem.getLine(dataLineInfo);
// Prepare the line for use
targetDataLine.open(audioFormat);
targetDataLine.start();
targetDataLine.addLineListener(myLineListener);
// Build an input stream from the line
AudioInputStream audioInStream = new AudioInputStream(targetDataLine);
// Create the output file
File outputFile = new File("C:\\MySampleAudioFile.wav");
// Start the actual audio file-writing operation
AudioFileFormat.Type targetFileFormatType = AudioFileFormat.Type.WAVE;
AudioSystem.write(audioInStream, targetFileFormatType, outputFile);
==============================
This code is executed in an independent thread. As you can see from the code reported above, I add a LineListener to my TargetDataLine.
The problem is that in my JWS application several seconds (about 5-6 seconds) elapse from the call to AudioSystem.write() and the reception of the START LineEvent on my LineListener. This delay only occurs when my JWS application is downloaded from my public internet website, while it is not present when I test my JWS application on my local LAN server.
It looks like the call to AudioSystem.write() causes some kind of network connection to the remote web server of the JWS app, and this operation takes some time. In fact, if I download my JWS app to my client from the public web server, then I disable all network connections on my client, then the START event is received immediately after the call to AudioSystem.write()... This is STRANGE, isn't it???
Do you believe the call to AudioSystem.write(), or any other Java Sound call, may cause a network connection to the server from which the JWS application has been downloaded?
A final addition to the above picture: I also have a "Java Applet" version of this application, which is exactly identical to the JWS version and uses the same exact code to do audio acquisition from the microphone. But, in this case the delay is not present, even when running the applet from the public web server!
Any help / suggestion would be highly appreciated.
Best regards,
Marco.

A JSP is not the same as a Java application. A Java application has package statment, import statements, try/catch block, a JSP doesn't.

Help with Java program and PKGBUILD

Hey guys, I'm fairly new to Arch and very new to making packages. I write a lot of my stuff in Java, and I know that Java is normally a pain to package on Linux systems. I have had a good look at the Java Packaging Guidelines, http://wiki.archlinux.org/index.php/Jav … Guidelines and I see that it says about not bothering compiling from Java source and just provide the JARs (am I correct?). So my question is, if I were to make a PKGBUILD for my Java based program, would the build() block just basically create the folders in the filesystem and move the content (JARs etc) to the folders? And then create the shell script in the appropriate location?
Forgive me I have the completely wrong idea...
Many thanks

 pls help me.

 You realy can do it like Xiang says, but the better way is to use packages. That's
 the way BEA is designed for. If you use packages you can but your bean classes
 in every subfolder beneath Classes. Here for example we have the subfolders test
 and beans:
 You have to declare the package on top of your Bean Source Code:
 package test.beans;
 In your JSP you don't need the import code of Xiang. You only have to refer the
 path of your bean class:
 <jsp:useBean id="testBean" scope="session" class="test.beans.TestBean" />
 There are some other AppServers that only can deploy Java Beans in packages. So
 if you use packages you are always on the right side.

Having Trouble with Java Mail and Servlets

How can I send and receive mails using Java Mail API and Servlets

You should familiarize yourself with the JavaMail API and the servlet API--this is much too broad a question to properly answer in a forum. The J2EE Tutorial shows how to send a mail message using JavaMail from a session bean, but the technique is similar to what you would use from a servlet:
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/Resources5.html#wp82097
I'm sure the JavaMail documentation has an example as well.

Problem with Java Dates and UPDATE for SQL2000

I am having problems with the date formats for Java. I am trying to put the current date time into a SQL table, here it the code I am using:
var Today = new Date()
var conn = Server.CreateObject( "ADODB.Connection" )
conn.Open( "Provider=SQLOLEDB;Server=(local);Database=BillTracking;UID=sa;PWD=;")
var sql = "UPDATE BillAssignments SET DatePosted = " + Today + " WHERE AssignmentID = '" + Request.QueryString("AssignmentID") + "'"
var rs = conn.execute(sql)
I keep getting different errors and I have been unable to find a solution yet. I know that I need to change the date format from the Java standard to the one that SQL likes.
Help....
Norm...

Please tell us where the Java part of this comes in. I see that you are using JavaScript to load up data via an ADO connection (presumably on an IIS platform) - but I do not see where you are using Java

Problem with Java keystore and certificates (unable to find valid cert path

Our program is made so that when a certificate is not signed by a trusted Certification Authority, it will ask the user if he/her wishes to trust the certificate or not. If they decide to trust the certificate, it will accept the self signed certificate and import it into the keystore and then use that certificate to log the user in. This works fine. It will import the certificate into the keystore and use the specified ip address to establish a connection with the LDAP server (Active Directory in our case) and authenticate properly. However, the problem arises when we then try and connect to a different ip address (without restarting tomcat, if we restart tomcat, it works fine...). It imports the certificate into the keystore fine, but always gives the exception
"Root exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
and does not authenticate with our LDAP server (which is Active Directory). The problem seems to be that it is no longer looking at the System.setProperty("javax.net.ssl.trustStore", myTrustStore);
I have tried multiple times to just reset this property and try and "force" it to read from my specified trust file when this error happens. I have also imported the certificates directly into the <java_home>/jre/lib/security/cacerts and <java_home>/jre/lib/security/jssecacerts directories as the java documentation says that it will look at those directories first to see if it can find a trusted certificate. However, this does not work either. The only way that I can get this to work is by restarting tomcat all together.
If both of the certificates are already in the keystore before tomcat is started up, everything will work perfect. Again, the only problem is after first connecting to an IP address using TLS and importing the certificate, and then trying to connect to another IP address with a different certificate and import it into the keystore.
One of the interesting features of this is that after the second IP address has failed, I can change the IP address back to the first one that authenticated successfully and authenticate successfully again (ie
I use ip 1.1.1.1, import self signed certificate, authenticates successfully
login with ip 2.2.2.2 import self signed certificate, FAILS
login again with 1.1.1.1 (doesn't import certificate because it is already in keystore) successfully authenticates
Also, I am using java 1.5.0_03.
Any help is greatly appreciated as I've been trying to figure this out for over a week now.
Thanks

Problem with Java Clasess and Arrays

Hello, i have a situation when a need to call a web services.
I have 3 classes..and a need to call a method
Class1 have a method
public void setIva(ArrayOfAlicIva value)
Class ArrayOfAlicIva is
protected List<AlicIva> alicIva;
This class not have a metho to set de object
and
Class AlicIva have 1 attributes call base int and method setBase
When imported to Forms, i have the package with this clasess...
The problem is when i have to call a SetIva Method.
In pl/sql i have
Case 1
OraAlicIva := AlicIva.new(); --OK
AlicIva.setBase(OraAlicIva , 10); --OK
Class1.setIva(Object_to_Class1, OraAlicIva); --Error, is not type excpected
Case 2
OraAlicIva := ArrayOfAlicIva.new(); --OK
AlicIva.setBase(OraAlicIva , 10); --Error, setBase is not defined
Class1.setIva(Object_to_Class1, OraAlicIva); --OK
Case 3
OraAlicIva := AlicIva.new(); --OK
OraAlicIva2 :=ORA_JAVA.NEW_OBJECT_ARRAY(1,'ArrayOfAlicIva'); --OK
AlicIva.setBase(OraAlicIva , 10); --OK
ORA_JAVA.SET_OBJECT_ARRAY_ELEMENT(OraAlicIva2 , 0, OraAlicIva); --Error, ExceptionStoreArray
Class1.setIva(Object_to_Class1, OraAlicIva); --OK
The Solutions in Java is
AlicIva[] alicIva = new AlicIva[1];
alicIva[0]= new AlicIva();
alicIva[0].setId(Short.parseShort(1));
fedr[0].setIva(alicIva);}
Is posible to Resolve ??
Thanks and Sorry for my inglish

Thanks for the answer but the problem is the type of object of method and how from pl/sql is posiblle to call.
The method waiting a ArrayofAlicIva, but if i define this object is not posible to set the object inside the array because the wsdl not have this functions.
I need to define array of objects but the object is inside is the diferent type of array.
If i Define the array of object correct to object inside, the method expect that the other array type.
Is a Deadlock ??
The solution in Java is Simple
AlicIva[] alicIva = new AlicIva[1];
alicIva[0]= new AlicIva();
alicIva[0].setId(Short.parseShort(1));
fedr[0].setIva(alicIva);
this is the method imported in java class to form
-- Method: setIva (LArrayOfAlicIva;)V
PROCEDURE setIva(
obj ORA_JAVA.JOBJECT,
a0 ORA_JAVA.JOBJECT) IS
BEGIN
args := JNI.CREATE_ARG_LIST(1);
JNI.ADD_OBJECT_ARG(args, a0, 'ArrayOfAlicIva');
JNI.CALL_VOID_METHOD(FALSE, obj, 'FECAEDetRequest', 'setIva', '(LArrayOfAlicIva;)V', args);
END;

Problem with Java Proxy and Socket Connection

Hi Gurus!!
I have developed a Java Proxy that connects via socket with a Server Socket application. This Server Socket application accepts more than one connection at the same time.
When I connect the first time from my Java Proxy, the connection is correctly established. When the first connection opened, if a try a second connection, this is not established.
I use "new Socket(SocketServer,SocketPort);" to open the connection.
I think that all time the Java Proxy is trying to open the same connection, and this is a problem.
Is there a way to indicate to the server that is a new connection and that the existing connections remain?
Anybody could help me, please?
Thanks and regards,
Manuel Míguez.
