Hi,
Enviroment:
OS: Ubuntu 7.04.
Server: Apache Tomcat6.
IDE: Eclipse3.2 + MyEclipse5.01
Axis1.4.
I have been trying to run the attachment example which locate ../samples.attachments.

-saxis/servlet/AxisServlet
-p8080 /home/hut/wanglinghua.java

I am trying to reinstall Windows on my macbook pro. I downloaded the support files and Windows 7 iso file to a USB drive. However, when I try to run the setup.exe program I get the message "this program cannot be run in DOS mode."

I am trying to reinstall Windows (would not launch). I removed the partition and started over. I downloaded the support files and Windows 7 iso file to a USB drive. However, when I try to run the setup.exe program I get the message "this program cannot be run in DOS mode." I was successful before, what am I doing wrong this time?

Try a restart.
If that doesn't fix the problem, shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.

Can't run the cluster example

 I would appreciate if someone can explanation my long list of questions regarding
 the deployment of EJB in cluster environment.
 I can't run the cluster EJB example( Teller/Account) in a cluster(contains two
 server2). I always get
 java.rmi.RemoteException: Unable to
 resolve examples.cluster.ejb.Account
 Home. Resolved: 'examples.cluster.ejb'
 Unresolved:'AccountHome'
 Following is my setup:
 Machine A: exampleServer:7001 (admin server)
 Machine A: testServer1:8001 (Managed server)
 Machine B: testServer1_B:8001(Managed server)
 MyCluster : testServer1, testServer1_B
 Test Client:
 java examples.cluster.ejb.Client "t3://Machine A:8001"
 ======================
 Q1: Should I use 8001 or 7001 as cluster port number?
 Q2: What will happen when we click "apply" after select/unselect the server in
 the "target", "server" tab?
 Q3: And what will happen if we click deploy/undeploy check box in "configuration"
 tab of EJB item?
 Q4: I check the JNDI tree from all above three servers can't find out JNDI tree
 doesn't reflect the change I did in Q2 or Q3.
 Q5: What is the right way to deploy EJB components, should we select both cluster
 and server in the "target" tab?
 Q6: I got this message from one of the server when I try to undeploy/deploy ejb
 object.
 "examples.cluster.ejb.TellerHome_EO in the jndi tree is non clusterable
 and you have tried to bind more
 once? How could I make it clusterable?
 Q7: Undeploy and EJB doesn't work and sometime I still get " JNDI name in use"
 from the server.
 How could I fix it.
 Thanks


First I can tell you that the ports have to be the same, be on the the
 same network , i.e. Telnet into the other m/c. Next which you probably
 have done is the properties files. Per-cluster ...

Help - running the Persistence Example

Hi All,
I am running on NW2004s SPS10
Please somebody has a Persistence example?? I can't run the SAP examples on my PDA (Dell AXIM X51v +Windows Mobile 2005) i found this information in the SAP Note 717510
MDK: Links to MI client home page are not working in some example programs
Application is working fine but for the ME Home link for 3 MDK applications: MDK_persistence_query_sortJSP, MDK_persistence_queryJSP and MDK_persistence_simpleJSP.
( Changed at 30.04.2007 )
I would like to run the MDK_persistence_simpleJSP
There is another Persistence example? Can somebody give me a link to download it. I want to learn how to use the persistence api, but without any running example is very difficult to test the code.
Best Regards,
Erick Ilarraza

Hi all! Thank a lot for your replies.
I run the MDK_PERSISTENCE_QUERYJSP in the Windows XP SAP Mobile Client, it runs Perfect!
But when i try to run it on my PDA it give me this error:

But this has no sense!! since both Windows XP MI Client and PDA MI CLient are at the same version. So It run in my Desktop but not in my PDA.
I saw the menu.jsp file
They used the PersistenceExample class in two places:
At the beginning of the JSP: <%@ page import="persistenceexample2.PersistenceExample" %>
And here:
String value = dataBean.getTableContent(i, j);
 if (i > 1) {
 value = PersistenceExample.encodeForHtml(value);
 if (value.trim().length() < 1){
 value = " ";
From a point of view of Java, everything appear to be "OK"
The other error is about a "version" should i configured the application to Version 45 in the nwa when i deploy the application?

Running the heapTracker example

Hi there
I am trying to run the heapTracker example that is in the demo/jvmti directory, and I am having problems with it. When I try to run it with what it says in the readme file (java -Xbootclasspath/a:heapTracker.jar), I get the following error message:
ERROR: JNI: Cannot find heapTracker with FindClass
It seems like a small problem, but it is making me go crazy! Has anyone else ever encountered this before?
Cheers
Sajid

Hi
Yeah, I managed to get it to work� I move the jar file into the same directory as the dll�s�seems a bit strange, but it worked.
A problem I am going to try and make some changes to the heaptracker, but I can not get it to compile, the errors I have listed below. It looks like I am missing a library or something, but I am not sure which. Has anyone else ever encountered a problem like this?

Help Running The SpeakHere Example

Hi,
I'm a newbie to iphone development coming from world of windows, so apologies in advance if it's a dumb question. I'm trying to run the SpeakHere example but so far unable to do so. The program compiles and launches, but freezes when I click 'record'. I tried to debug, and it seems to crash at:
recorder->StartRecord(CFSTR("recordedFile.caf"));
At least it doesn't go past this line (there's no error). So far I checked that audio input works in another app (garage band), gave the speakhere's sandbox full permissions, made sure I have the latest version of the os and sdk, and now not too sure what to do. Any help greatly appriciated.

Problem Solved:
After discovering where to look for errors I found that the error was:
Error loading /Library/QuickTime/DivX Decoder.component...
The solution was to remove the decoder and encoder from the /Library/QuickTime folder.

Are you in US Eastern Time? This looks like an offset due to time zone (EST is -5 hours). Setting the UTC constant to TRUE will fix that.

I just got v10.6, while trying to run the update, it's telling me that the file is corrupt and cannot be saved. What do I do?!

I'm running Snow Leopard v 10.6 on a Macbook 4,1. I've got a 500 GB HD and 4GB of Ram. While trying to run the software update (to get me to 10.6.8, I think?) I keep getting an error message around 600 MB that says it's unable to be saved because the file might be corrupt and that it will try again when the software update is ran next time. Why am I getting this message? Is there a way to get the update (so I can eventually get to Lion), without going through the software update screen?
I'm going crazy with this. I've tried 4 times now and still keep getting the same message.

Try downloading the stand alone installer here:
http://support.apple.com/kb/DL1399
In Safari Preferences, General tab, set "Save downloaded files to: select destop, if it is not in thed rop down select other, then selcet Desktop from the left sidebar. After the download completes click on the installer package on your desktop and follow the prompts.
Also if possible use an ethernet conection as it is less prone to interference, thus less prone to corruption, and usually faster.
Hope this helps

Error 1073807331 when trying to Run the "servo" example in Labview.

Error -1073807331 occurred at Property Node (arg 2) in VISA Configure Serial Port (Instr).vi->LabVIEW Interface for Arduino.lvlib:Init.vi->LabVIEW Interface for Arduino.lvlib:Arduino Servo.vi
So, I can connect to the Arduino Mega 2560 in MAX and also in VISA, but when I try to run this example, I get the above error. with the explanation "The specified attribute is not defined or supported by the referenced resource."
the ONLY error i can see in VISA is this :
under Configuration/View attributes- "Interrupt in pipe status | VI_ATTR_USB_INTR_IN_STATUS | Invalid Property Value"
this is in red., all other text is in black.
Under "Input/Output" I can write to the board "*IDN?\n" and get a return of 6bytes which it appears happy with.
Query button appears happy as well.
as does "Read"
the "read status byte" button gives me "
Read STB Operation
Error
VISA: (Hex 0xBFFF003A) Unable to start operation because setup is invalid (due to attributes being set to an inconsistent state)."
I am at a loss as to what to do about this as I cannot see a way to change this value.
Any help is greatly appreciated.
thanks

OK, well I know how to connect the arduino to my PC as well, its simple.
I have been playing around with the mega2560 for over a year, so it's not that.
I can connect to and talk to the 2560 from the arduino IDE, but not LabView. I did see both TX and RX activity tonight, and thought, "yay! its finally stopped being retarded", but as soon as I hit run, it fell back to the old"cannot find arduino"
the reason I was using VISA was because I couldn't get any joy from the serial/USB method.
If I somehow mange to let the magic smoke out of this, I doubt I'd be very upset bout it.
anyway, any other ideas?
Cheers
Jason

Got NullPointerException we I try to run the attachment example of Axis1.4.
