10 minute hang in our Java application on HP-UX only...
To simulate a network outage, we unplug the network cable from the box. Our Java application hangs for 10 minutes on the first #sql statement it encounters, then finally returns an exception. On Windows and Linux boxes the exception is returned immediately under the same conditions.
Is this an HP-UX com issue, or an Oracle issue?

It seems that the Java Environment can't connect to the Display (perhaps no XServer is running or the display variable is not set correctly)
This seems to be the case when the call
java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(GraphicsEnvironment.java:62)
fails.

Our Java application is built with java 1.4 version and oracle 10g

Our Java application is built with java 1.4 version and oracle 10g version database, is it possible to upgrade oracle database to 11g?

is it possible to upgrade
Yes. SE and the other editions have a migration/upgrade utility, not seeing any mention of that program in the XE license docs. To upgrade to 11gR2 from 10g, the 10g instance must be at patch 10.2.0.2 or higher.
So if you're a GUI dba, might be out of luck. But the the XE install has the catalog upgrade scripts that need to be run, there is a MOS note explaining the manual upgrade steps.
Or set up a brand new 11g database instance and datapump your user schema(s) from the 10g instance to the new 11g instance. The database doesn't care what java version you're using, it just does what its told with the data. DDL, DCL, DML ... its not much different. Quite a few new features in 11g.
But if you're after JVMs that piece is not supported with XE.

Issues while configuring java application using JDO with MS JDBC Driver 1.0

I have already tried this before and this not work too, but strange that even if I use JDBC:ODBC bridge driver, the return value for output parameters are not correct, that is, only return the value that I input but not the value after executed in the procedure....
The code that I used with JDBC:ODBC bridge is as follow:
public static void main(String[] args) {
String url = "jdbc:odbc:;DRIVER=SQL Server;Persist Security Info=False;database=db;Server=sql;uid=sa;pwd=pwd";
          Connection con;
          ResultSet rs = null;
CallableStatement callS = null;
          try {
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
          } catch(java.lang.ClassNotFoundException e) {
               System.err.print("ClassNotFoundException: ");
               System.err.println(e.getMessage());
          try {
               con=DriverManager.getConnection(url);
callS = con.prepareCall("{ call dbo.CpJavaTest (?)}");
callS.registerOutParameter(1, Types.INTEGER);
callS.execute();
rs=callS.getResultSet();
int ret = callS.getInt(1);
System.out.println("return value : " + ret);
               while (rs.next()) {
                    String f1 = rs.getString(4);
                    String f2 = rs.getString(5);
                    System.out.println(f1 + " " + f2);
          } catch(SQLException ex) {
               System.out.println("SQLException: " + ex.getMessage());
The value of the output parameter is same as what I inputed! Hope any one can teach me how to correct it...
Thank you very much!

Embedding video in Java Application

I'm a total newbie, trying to decide if Java is the way to go for our application.
We want to be able to create an interactive application with buttons, drag & drop, data input fields, hot spots, etc
AND also show video... windows format, apple format, flash format.
We want our application to be deployable either as...
1 - a standalone app... running on a system not on a network or the internet
2 - a web app
We want the video player to be embedded in the application and not launch a player in a seperate window... thus we want to maintain as much control within the confines of our application as possible.
MY QUESTIONS:
1 - Will the Java Media Framework allow us to embed movies in our application as described?
2 - Is it fairly easy to code such in our Java application?
3 - Any code snippets around?
4 - Re: Standalone/CD distribution version: Can the JMF be installed along with the application so the client doesn't have to "go out and install more stuff" ??
5 - Re: Web - must the user download and install more stuff... other than the Java Virtual Machine to have the JMF work on their system?
6 - Is the JMF multi-platform... Windows, Apple, Unix/Linux, etc like the JVM ?
thanks for any help on this. Will

Yes all of what you require is doable in Java
Try
http://java.sun.com/products/java-media/jmf/2.1.1/solutions/index.html
Check some of these samples
Also for a web version check
http://java.sun.com/dev/evangcentral/totallytech/jmf2.html
(Haven't studied this myself - but should give you an idea or two)
Platform-wise - check here
http://java.sun.com/products/java-media/jmf/2.1.1/download.html
In terms of CD distribution - you should be able to package most stuff into a Jar file
Not completely sure as there are 'Windows Performance pack' downloads which I think toake advantage of native DLLs
Have a read around the JMF Installation pages - should answer most of your questions

How to use third party package in java application

hi, i am a student , new to java world can any of u tell me how to import third party package in our java application.
i want to know how CLI is done in java.
i am going thru this link http://www.codezoo.com/pub/component/5574
not able to get anything.
please please help me

There are two steps -
1. Import the classes you need from the package(s) using the Java import statement in your classes that need access to them.
2. include the 3rd part code (one or more .jar files and/or root directories holding the code's package tree and .class files) to your javac and java class path and optionaly to the class path found in your .jar's manifest file.

JAVA application packaged as an EAR

we are upgrading our system to Oracle 12i and we have a custom java application that access the Oracle API. As part of this upgrade we have to deploy our JAVA application packaged as an EAR file to OC4J that comes with Oracle EBS. All we need is sequence of steps/ some document that will help us deploy our JAVA application(EAR file) to OC4J server.
1. Can we create another instance of OC4j in Oracle 12i(12.1.3)?
2. Will there be any integrity issue if we deploy ear file to Oacore/Forms/OAFM oc4j instance integrated with R12? or Do we need to create a new instance?
3. I was told by the support engineer that there is no EM console for oc4j integrated with R12, so is there any script provided by oracle to do any ear deployment?

Accessing User Name in a JAVA application from a PKI certificate

Our JAVA application needs to verify the username from a PKI certificate. Is there any way to access this information. We are developing using Oracle JDeveloper, Oracle App Server and db.
Thanks,

I don't know if it is possible to run the main method from another Java app by simply calling it...
But you could just copy and paste the stuff from your main method into a new static method called something like runDBQuery and have all the execution run from there.
How does that sound? Is it possible?
What I'm suggeting is:
Original
public class DBQuery{
public static void methodA(){
public static void doQuery(){
methodA();
public static void main(String[] args){
// Your method calls
//Your initializing
doQuery();
}Revised:
public class DBQuery{
public static void methodA(){
public static void doQuery(){
methodA();
public static void doMyQuery(){
// Your method calls
//Your initializing
doQuery();
// No main needed!!
//public static void main(String[] args){
// Your method calls
//doQuery();
//}

JDeveloper Team - How to print Barcodes from java application

We are developing an Inventory based application in JDeveloper 3.2.2/Oracle 8i/Netscape Enterprice web server on Windows NT platform. The application is developed in swing technology.
We have to print Barcodes on Intermec 3400/4100 or Zeebra Z4000 (connected to COM1/COM2) from our java application from one of our screens.
Can you please point me to right place or get me sample source how to achieve this. We are working on a timebound deadline and we are really counting on your sincere response ASAP. Thanks in advance.

Try creating a page called launcher.html (for example). That does this:
<html>
<head>
<script language="javascript">
windowHandle=window.open("http://www.javasoft.com", "", "height=700,width=1000,status=no,scrollbars=yes,resizable=yes,toolbar=no,menubar=no,location=no,top=5,left=5");
</script>
</head>
</html>Now you launch IE (or whatever) with this page using the Runtime class. After x seconds (after the second window has been launched) try killing the process. Hopefully it will kill the original window you opened and not the window you popup (the one without toolbars etc)
It might kill both windows but I can't be bothered to test it. If it does you'll have to try and find a workaround.

Java application crashes and generates a hs_err_pid.log file

Our Java application receives JMS messages in XML form, parses and pre-processes them and forwards to an analysis engine (Gensym G2) for further processing/auto ticketing. The application crashed when processing a JMS message. This issue could not be reproduced and does not happen everytime the same JMS XML message is received.
Any ideas on the cause of this core ?? The application is running on Solaris 9 ans using JRE 1.6.0_11-b03

jschell : thanks for ur response. We have been pursuing the possibility of it being a JNI related issue. As per the stack trace, SIGSEGV occurred in [libc_psr.so.1+0x740] memcpy+0x260. We checked the code for any memory related issues. Our application does not use JNI directly but we use 3rd party jars -is there a way to check if these jars are using this particular library - so we can report to the respective vendors ?? This library path is shown as : /usr/platform/SUNW,Sun-Fire-V490/lib/libc_psr.so.1
nambar: thanks. we are also testing if the issue is related to accessing the jar files.
Your responses are very helpful in indicating that we are looking in the right direction!

Technical considerations to migrate Java applications to NWDS 2004s

I see important that SAP, gives a guide to say the technical details to us that we must consider to migrate our Java applications to NWDS 2004s. It is important to know this because we must consider risks, times, to make these tasks with our clients.
Thnks.

Hi Josue,

Multi-threaded java application and deadlock down in Oracle library

Hello,
I was running our Java (JDK 1.6_14) application from Windows XP hitting an Oracle (10g) instance on Linux and came across a deadlock issue with two (of 10) threads. Below is the stacktraces (based on Java thread-dump at the command line). This code I've run 30-40 times with no problems of deadlocks.
The Oracle library that we're using for our Java application is ojdbc14.jar and sdoapi.jar (for spatial).
We create our Connection as follows (for each thread -- 10 of them):
public class Worker implements Runnable
private Connection _Conn;
public Worker(...)
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
_Conn = DriverManager.getConnection(url, username, password);
_Conn.setAutoCommit(false);
The code that is already executing these same lines below was already executed by other threads (in their own instance of Worker). So this is very confusing.
Any ideas? Version of the .jar files? Place how we're calling "DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());"?
Thanks, Jim

Thanks Toon for your reply.
Yes each Worker (executing in their own thread) has their own instance of Connection as per the Constructor (shown in original post). That is why this is weird.
I'll check the v$session when I get into work.
Based on our code that I put in the original email, Connection is a non-static variable. We have a per Thread per instance of Worker of which that Worker instance has its own instance of Connection. So I'm wonder if the following needs to occur:
Both of these lines (from original email) need to happen in the main thread as follows:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
for (i=0;i<NUM_OF_WORKERS)
_Conn = DriverManager.getConnection(url, username, password);
new Worker(_Conn);
Thanks,Jim

Executing a Java application from JAVA

Hello all,
I have a problem spawning a Java IRC client from another Java application. The client only manages to execute itself properly [join a specific channel] once the original parent application has been closed. Any ideas?
The code is as follows:
public void run(){
     String[] cmd = {"java", "IRC"};
     try {
           Process p = Runtime.getRuntime().exec(cmd);
          p.waitFor();
     } catch (Exception exc){
          print ("Could not run the IRC session file" + exc);
}

Well, if you ask me, it's not very good Java style to try to access the command line to run ANOTHER Java application.
My suggestion is simply call the IRC program's methods to get it started. Don't bother with Runtime.exec.

10 minute hang in our Java application on HP-UX only...
