HI,
I made some code changes, now I am getting the following exception.
I will describe the process. As I told this thing works fine on my s/m. But while trying to deploy on other s/m it�s giving this error.
After RMI server is up I will setup my application�s server. Server will start without any problem. And in the client side first screen is the login screen. If server is not running we wont get the login screen. But up to login screen there is no problem. This error is generating when we are trying to login.

Xsi namespace not bound

Hi,
I call a webservice and parse the response into an XMLBean. The problem is that the namepace xsi is defined by weblogic in the SOAP header - which must be stripped before loading the message into the XMLBean. So when i do a parse, elements with xsi:nil throw a not bound exception...
com.bea.xml.XmlException: error: The prefix "xsi" for attribute "xsi:nil" is not bound.
So how do i tell the XMLBean about the xsi namepace? Any examples gratelfully received!
Thanks
Neil

Well, have a look at the API:
public StreamSource(java.io.File f)
Construct a StreamSource from a File.SCNR ;)

Exception is thrown "mydb is not bound"(needs urgent help)

We r three students and our final project is a BPM(Business peocess Management)system.
BPM is actually a workflow system(managing the business processes)and all the rules and constraints are applied from the Rule Management System.
we have started the implementation, and therefore we need some help related to the implementation.
We r using EJB2.0 with JBuilder9, JBoss3.2 as the application server and tomcate as the web server.
problem:
I want to create manual database connection using DataSource,
I am using mysql and database name is mydb.
I have done all the reqiured configration of mysql with Joss and it is working.
After getting the initial context, when i try to lookup the datasource, exception is thrown "mydb is not bound"
Initial context is correct because i have tried entity beans asd it works well.
code is
Hashtable contextValues = new Hashtable();
contextValues.put(Context.PROVIDER_URL, "jnp://loopback:1099");
contextValues.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
Context context = new InitialContext(contextValues);
context.lookup("java://mydb");
Kindly help me if u find time,

JNDI Exception : [System] not bound in naming services

Hi All,
Is there any way to resolve this JNDI exception "Invalid Path: [System/Launchers] not bound in naming service" ?
Thanks in Advance

This did not work dear. I assume when you say [Add ur datasource], you mean the name of the datasource, and I did as you told. I was wondering though that I have an independent java class which try to get data source from WSAD server, then how does web.xml help, may be I am not understanding the connection here.
Just to let you know, that same java class gets the datasource from 4.0 test server. I am running both servers now i.e. 4.0 test and 5.0 test server on different ports, and only data source from 4.0 workd good. Do you have any other solution, which I can try.
Is there any difference the way data source is accessed between 4.0 and 5.0 versions.
Thanks in advance.
Open web.xml, There will reference tab,, then take
Resource, Add ur datasourse on where the Cursor points
and then JNDI Name.
U need to restart ..

Why i get servlet exception/login servlet not found exception with .ear ?

I am able to deploy my war and after that generating the ear from that. both works fine in local system.
But when i run (Jboss as service[Java Service Wrapper]) it takes war without any problem.But with ear file i am getting servlet not found exception.I can't understand where this problem is coming from.
Even if i take my JSPWIki ear which is running well in production server, this also gives same error.
One more thing, the files, what i am running well in local system i.e. war and ear working fine. (can't test in production server so testing in same kind of testing server) there also getting login servlet not found exception. Even in same location other files which are deployed are working fine.out of 4 at least one is working fine.
I don't undersatnd where this whole problem is .
Please guiide me where sholud i concentrate to solve this problem.

I took the source code including the dll files already added to the project from here:
spazzarama/Direct3DHook
The solution include two projects the one name Capture is class library type and the dll that make the exception is in this project.
I tried now to use the program Dependency Walker on this dll file and it found error/s:
This is the log:
Error: At least one required implicit or forwarded dependency was not found.
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Warning: At least one delay-load dependency module was not found.
Screenshot:
It happen only when using/detecting Direct3D 11 . So far only in Direct3D 11, When i use it with a game that run Direct3D 9 it's working fine.
The question is how can i solve this dll problem ? Any site/place to download this dll from ?

T430s - [Solved?] Wireless hardware is not bound to transport driver (Centrino 6205, Win7x64)

Hello,
after clean install of my new T430s using System Update everything worked quite well, except for terrible DPC latency when loading web pages (crapping sound). Therefore I changed LAN driver to 11.10.84.0 from Lenovo (83rw15ww) and latencies went down (this driver has been recommended in some online forum).
Few days later I was on WiFi and latency spiked up again, but this time all the time above 8000µs - even when idle. I started to play with devices in Device Manager and ultimately reinstalled WiFi driver to Lenovo's 15.6.1, then Intel's 15.8.0. The most recommended driver from HP I was unable to install, so no harm there
Not sure when, but somewhere since this point I don't see wireless networks any more. Driver is fine (no yellow ? or !), wireless card is fine (replaced by spare one from my "HW guy"), all drivers has been reinstalled MANY times. When I try to add WLAN manually, Win7 says "Unexpected Error". Diagnostic tool from Intel says "Wireless hardware is not bound to transport driver". In Fn+F5 I see WiFi as off and I can't turn it on (unlike Bluetooth, which works well). Windows Diagnostics says there's an issue with a driver (sorry if I don't use exact words, my Win7 is not EN). I don't see this card anywhere in "ipconfig". There's no difference in diagnostics whether the wireless switch is on or off.
I read almost everything I was able to google about similar issues. I tried various drivers from both Lenovo (manual download from Lenovo website as well as using System Update) and Intel, both with and without Access Connections. I tried to remove the device from Device Manager and let Windows to find it again. I reinstalled LAN driver, tried to update BIOS (was already updated), tried to reset various stuff using "netsh" command, deleted Intel/Wireless dir in [username]/AppData, all this with/without reboots in between. Tried to play with card settings (in Device Manager), with power settings (both Windows and Power Manager), with on/off switch on a side of the laptop. I tried System Restore, which ended by error for all meaningful points. Nothing. All this on 3 different WLAN networks (2.4 GHz).
My last thought is to reinstall Windows from scratch, but it takes me at least 2 whole days to set everything up as I use a boatload of different work stuff for different customers.
My current WiFi driver, according to Driver tab in Device Manager for Intel Centrino Advanced-N 6205, is 15.4.1.1 from January 23, 2013 (thru System Update). The more current one from Intel is 15.7.0.3 from April 18, 2013.
Thank you in advance for any suggestions, tips or help.
EDIT
Just for the heck of it I switched wireless ON at home and suddenly my home WiFi network appeared in Win7 WiFi management (no AC). The last driver I installed was thru System Update, twice. Never restarted immediately, always after a while.
So I ran System Update again and it offered me available driver for WiFi (again!) and Access Connections. The online utility from Intel also offered me available drivers. I still have WiFi driver 15.4.1.1 (23.1.2013). To be honest I'm little affraid to update one or the other, as I did it so MANY times in past 30 hours with no effect.
The only difference I noticed is a new wireless device was available - Microsoft Virtual WiFi Miniport Adapter. It may be because of my Checkpoint Endpoint Security VPN software, but last time I saw this adapter was just before I lost all the wireless networks.
As much as I'm relieved it's working again, as a programmer I'm not happy about it, because I don't know WHY it's working now, when I didn't do anything for it since my last try. I only kept the wireless switch off for a fair amount of time.
Oh, and DPC latency stays below 300µs (up to 500µs is OK).

hey smarmytime,
let me get this right
laptop+router+modem (via cable) = connection working fine
laptop+modem (via cable) = connection goes wonky
laptop+wireless = works halfway then poofs
The wireless of yours comes from a Router+Wifi or is it coming from a Modem+Wifi set ?
If it's coming from a Modem+Wifi set, then try the following.
1- turn off wireless
2- reset modem to factory setting (make sure wireless is off)
3- key in the necessary info to make a connection.
4. switch wifi off on laptop
5. connect laptop to modem via cable.
Does it connect ? Does it go poof halfway?
After that, turn on the wireless for both modem and laptop, try connecting again. Does it connect ? Does it go poof halfway?

Coz this is the common problem most of the programmers face initally

Not able to start the remote server - class not found exception

All,
I am quite new to RMI programming, although i am an experienced java programmer. I am facing a problem in starting the remote server program which i wrote for RMI. I am getting class not found exception for "stub" class eventhough the class is in the classpath.
Following is the error console:

Following are my classes:
MyRemoteInterface.java
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface MyRemoteInterface extends Remote {
public String[] getNames() throws RemoteException;
public class MyServerImplementation extends UnicastRemoteObject implements
MyRemoteInterface {
public MyServerImplementation()throws RemoteException{
super();
public String[] getNames() throws RemoteException{
return new String[]{"Name1","Name2","Name3","Name4"};
public static void main(String args[]) {
try {
// Create an object of the HelloWorldServer class.
MyRemoteInterface obj = new MyServerImplementation();
// Bind this object instance to the name "HelloServer".
Naming.rebind("rmi://localhost:1985/GetNames", obj);
System.out.println("GetNames bound in registry");
catch (Exception e) {
System.out.println("GetNames error: " + e.getMessage());
e.printStackTrace();
public class MyRMIClient {
*@param args*
public static void main(String[] args) {
try {
MyRemoteInterface remObj = (MyRemoteInterface) Naming.lookup("rmi://localhost:1985/GetNames");
System.out.println("Names are "+remObj.getNames());
catch(Exception e) {
System.out.println("Problem encountered accessing remote object "+e);
}

That's a remote exception coming from the registry. You need to learn to recognize remote exceptions and their source, it's a mjaor source of confusion in RMI.
In this case it's the registry that can't find the stub class.
The stub class needs to be in the CLASSPATH of (i) the Registry and (ii) the client as well. Ditto the remote interface; ditto any application classes it refers to, and so on until closure.
The easiest way to achieve (i) is to start it in the server's JVM, with LocateRegistry.createRegistry().
