Build problem with Hello1 example.

Hi,
I have installed j2ee1.4 and trying to run the j2eetutorial1.4
I am facing a problem in building the hello1 example.
1) When I build the hello1 example, the build fails with the following error message
C:\java-works\j2eetutorial14\examples\web\hello1>asant build
Buildfile: build.xml
init:
prepare:
copy:
build:
[javac] Compiling 2 source files to

C:\java-work
s\j2eetutorial14\examples\web\hello1\${j2ee.home}\lib not found.
Total time: 1 second
2)) Editing the build.proerties file to include the j2ee.home property.When I save the file it gets a .txt extension.Could this cause a problem , while I try to build the examples? if so How can I avoid this?
Could anyone please help me in this?
Thanks,
Ann

To save the file without .txt extension
just enclose the file with double quotes
"build.properties" in the File save dialog box

See full exception chain for details.
Correction Hints
The currently executed application, or one of the components it depends on, has been compiled against class file versions that are different from the ones that are available at runtime.
If the exception message indicates, that the modified class is part of the Web Dynpro Runtime (package com.sap.tc.webdynpro.*) then the running Web Dynpro Runtime is of a version that is not compatible with the Web Dynpro Designtime (Developer Studio or Component Build Server) which has been used to build + compile the application.
Note: the above hints are only a guess. They are automatically derived from the exception that occurred and therefore can't be guaranteed to address the original problem in all cases.

Export Release Build - Problem with Server Settings

Hello, i have a big problem and i searched the whole day yesterday but didnt found an answer...
I started a Flex Mobile and PHP Project. The Project has a Data/Services included wich loads some customer from a database (sql)... for the first a
used Zend and try it local (http://localhost and used the htdocs Folder of Zend)... EVERYTHING WORKS PRETTY FINE... so NOW my problem
I wanted to export this project to a release build for my android phone... so the first warning of Flash Builder ist that the project ist currently configured to access data services from a local url. Before exporting the application, you may need to deploy your services to a remote server, then change the server root URL for your project. Click here to change server settings.
When i click the button i get the server setting.
Web root: C:\Program Files (x86)\Zend\Apache2\htdocs
Root URL: http://localhost
whe i change it now i get an eror:"The selected web root folder does not exist (i attached i screenshot of it).
i entered de domain of my server (i also tried the ip) at Root URL. And i think there ist a problem with the Web root...? i get scary

i know WHY Flashbuilder tells me that i have to change the setting when i deploy on the device
my problem ist that i got this error...
and the domain wich i have in the screenshot should only explain how i tried it...
i entered my server url (the real domain) and i entered the folder "app" wich i have created via ftp on my server...
BUT i also get this error (lik in the screenshot)
i think at ROOT URL i cant make lot mistakes .... http://myserver.de or the ip
but i think maybe my web root ist incorrect? i entered here the folder wich is directliy on my server...?
i dont know exactly but i got an error like in the screen

LabVIEW 8.5.1 Build Problem With LV2010 Installed

I am experiencing a problem when building an application installer using LabVIEW 8.5.1. I have built this application many time before but since installing LabVIEW 2010 I can no longer build the installer.
I have tried to buiuld the application on a Windows 7 PC and a Windows XP machine. My minimum requirment in my build options was Windows 2000, I changed that to XP but it made no difference.
I get the following error message:
CDK_Build_Invoke.vi.ProxyCaller >> CDK_Build_Invoke.vi >> CDK_Engine_Main.vi >> CDK_Engine_Build.vi >> NI_MDF.lvlib:MDFDistCopyList_GetCount.vi
Loading product deployment information

*** Error Details:

*** End Error Report

Has anyone else come across this?
Thanks in advance.

Thanks Andrew.
It didn't help. After three days of trying, I did get one system to build without error. I'm currently trying to get another system to build.
It looks like the Access violation is caused by the deployment utility not asking to change to DVD 3 for CVI after the product caches has been cleared (To fix the error code -40 problem). Restoring the CVI runtime (NI LabWindows_CVI 2009 Service Pack 1 Run-Time Engine [9.1.1450]) to the Product Cache seems to fix the problem.
The status log doesn't show enough information to figure out the problems. Looking at the end of the Detailed_Installer.log is pretty much manditory.
My recomendation is to build first with "Install TestStand Engine" and the various "Driver and Components..." turned off and then slowly enable the ones wanted.
Also, it saves a lot of pain and suffering to do at least one deployment with "Copy Installers to Product Cache by Default" turned on before doing an upgrade so you don't have to go search for old DVD's.
After a lot of trial and error, I believe these are the steps I went through to finally get it to work:
1. Close TestStand, LabView, and Deployment Utility
2. Delete all in C:\Program Files\National Instruments\Shared\ProductCache, except the CVI Runtime
3. Delete all in C:\Documents and Settings\All Users\Application Data\National Instruments\MDF\ProductCache, except runtime 7.1.1
There seems to be something wrong with the .NET language pack installation. It always seems to generate errors.
3. Run DotNet20x86langpack.msi on the Device Driver DVD at Products\DotNet20langpack_x86_Installer\ and uninstall.
4. Run DotNet20x86langpack.msi and install.
5. Put DVD 1 back in.
Got an error with the .Net installer so. . .
6. Uninstall at D:\Distributions\LV\Products\DotNet20_x86_Installer\DotNet20x86
7. Install at D:\Distributions\LV_SE\Products\DotNet20_x86_Installer\DotNet20x86
8. Again Install at D:\Distributions\LV\Products\DotNet20_x86_Installer\DotNet20x86
9. Run TestStand, LabView (if using VI's), and the Deployment Utility.
Runtime 8.5.1 should install automatically and ask to reboot the system. Go ahead reboot and run Teststand, etc. again.
10. In global settings, 'clear prompt before'. . . , and select 'copy installers to product cache by default'
11. On Installer Options tab, clear "Install TestStand Engine".
12. Build - ALWAYS 'remove all files from this folder before building'
It "should" build. If not, fix any errors.
12. Select Install TestStand Engine.
13. Select Engine Options... and clear all check boxes (except runtime 7.1.1)
14. Build again (make sure DVD 1 is in)
15. Install other Engine Options, Drivers and Components.
16. Build again (make sure DVD 1 is in)

Problem with aurioTouch example program

Is anyone else having problems getting the aurioTouch example program to work in the emulator? I seem to have problems with any and all audio -related functions? What could be the problems?

Cedric,
This problem was fixed in the LabVIEW 6.0.2 update. You can download this update (along with the updated runtime engine) from our website.
Good luck with your application, and have a pleasant day.
Sincerely,

Reading TDMS files in Matlab - problems with the example code

I want to use the TDMS files to store data and do offline analysis in Matlab, version 2009b (either on Mac OS10.6 or Windows XP).
To test the data import in Matlab I tried the example from http://digital.ni.com/public.nsf/allkb/0EEADA99DC7D00A4862572E30037C3A2 , but without success.
I tried either with and without the path definition (as explained on the page I referred to before) at the start, and got back the following errors:
with:
??? Error using ==> loadlibrary>deltempfiles at 559
nilibddc_m.i.
Error in ==> loadlibrary at 452
deltempfiles(delfiles);
Error in ==> Read_TDMData at 7loadlibrary([examplePath '\nilibddc'], hfile);
without:
??? Error using ==> loadlibrary>deltempfiles at 559
nilibddc_m.i.
Error in ==> loadlibrary at 452
deltempfiles(delfiles);
Error in ==> Read_TDMData at 36loadlibrary(NI_TDM_DLL_Path,NI_TDM_H_Path);
I found a few messages on the issue, dating from 2006 and 2007, that didn't lead to a satisfying solution and was hoping that, by now, there would be a solution to my problem.
Thanks a lot
Remco
Solved!
Go to Solution.

Hi Musk,
Thanks for your answer.
Unfortunately it didn't help as my problem is not discussed there. I have a problem with this line:
loadlibrary(NI_TDM_DLL_Path,NI_TDM_H_Path);
I said before that I was using 2009b, but I was mistaken, I have R2008a, but the 'loadlibrary' is opened in a 2008b editor (no idea why). On the Mac I have 2009b installed.
Thanks
Remco

Problems with axis example

Hi
I'm trying to run the example TestClient.java that comes with axis, but I get:
java.net.ConnectException: Connection refused
Does anyone know if this server is still running and on the same port (5049) or if there's just something wrong with me.
Thanks

Problems withe transport example

Hi,
I'm trying out Oracle lite 10g on Windows XP. I've installed the mobile server with examples and now I want to install the Mobile Client on the Win32 Device. After synchronising I tried to install the transport application. This works without error messages. Then I opend the update-window (I think ist the one in the start-menue) but there is nothing to install. I find no transport.exe on the whole device.
Then I looked on the Mobile-Server. There are two transport.exe files in the folder <oracle home>\Mobile\Server\samples\Transport\Win32\bin and <oracle home>\mobile_oc4j_\j2ee\home\applications\mobileserver\samles\Transport_win32.
What's going wrong with my installation?
Best Regards
Mark

Hello Jorge,
I have the same problem with PPC2002. I posted this problem at September 17th. But nobody replied.
Problem registering PPC 2000 Client
The Device can't register with the Device Manager on the Server. I updated the firmware of my client and everything else what I thought could cause the problem.
What language has the PPC2003 system of your device?
Perhaps the problem is that only the english PPC2003/2 system is supported. Because I have the german version of PPC2002. Hopefully someone from Oracle or someone else responds to this thread.

Problem with BIB examples

Hello,
I have some problems with BIFrame.java (bootstrap project)
when i try to connect :
oracle.dss.bicontext.BINamingException: BIB-14736 BIUser does not exist in the BI Beans Catalog.
However, I used BIBCAT login.
A solution ?

hi,
ensure that in the BIFram.java code the line
private static final String m_configFile="***.xml";
contains your .xml configuration file,and that the userName and password in the DAD files are correct

Problem with "asant build" in J2EE hello1 example

Hi all,
I'm trying to follow the J2EE tutorials the examples contained within,
but I seem to have a hurdle with the very first example!
Basically, when I type "asant build", nothing happens - nothing is echoed back, and it looks like the build process has hung.
As far as I can see, I've defined my PATH etc. OK - as follows:
E:\Sun\j2eesdk1.4_beta2\bin;E:\Sun\j2eesdk1.4_beta2\share\bin;F:\bea\jdk141_03\bin
I've defined the following in build.properties as follows:
j2ee.home=E:\Sun\j2eesdk1.4_beta2\
sunone.home=${j2ee.home}
admin.password= (removed for obvious reasons!)
admin.host=localhost
admin.user=admin
Does anyone have any ideas?
Best wishes
Paul

Honestly I must say everything is a bit suspicious. I think there is a bug more walking around.
j2ee.home=E:\Sun\j2eesdk1.4_beta2
should work but I saw with this asant tool that the \ is not recognized as a directory separator.
j2ee.home=E:\\Sun\\j2eesdk1.4_beta2
works because asant recognizes \\ as a directory separator. For my taste this a wrong representation, because it is the internal representation in the program.
The entry should not use the internal program representation, so it is a bug.

Build problem with external JAR

Hello,
I am developing a custom web dynpro component. I need to use some of the JARs delivered by SAP such as com.sap.security.api (can be found in \SAP\IDE\IDE70\eclipse\plugins). I have included the JAR files to my project in Properties->Java Build path->Libraries). Everything is working fine: I can build/deploy the application and it is running fine in the application server.
Anyhow, the problem comes when I try to activate my activity in the development configuration perspective.
In the build log I can see for example the following:
[javac] ERROR: /usr/sap/VDD/JC10/j2ee/cluster/server0/temp/CBS/3/.B/4789/t/067D33924E6154CA5284F16652954F88/gen_wdp/packages/com/mydevelopment/mystuff/MyComponent.java:29: package com.sap.security.api does not exist
[javac] ERROR: import com.sap.security.api.IUser;
I have been reading several threads about similar issues, but I am not quite satisfied with the answers. There seems to be several opinions about how to solve this.
Now the questions are:
- How can I get rid of this error?
- What is the best practice in overall to use the SAP delivered JARs in custom web dynpro component/project.

Hi Pa,
To use any jar in your DC on NWDI track, you need to follow the following steps:
1. Go to Your project>Used DCs and try to add a new one by locating the DC among those which are already present on the track.
2. If you are not able to locate any DC with the required jars then,
a. Create an external library DC where you need to add all the jars in the library folder of the project using an activity.
b. Create public parts for compile time and run time for this dc.
c. Deploy the DC.
d. Goto src folder of your dc and say Add files to DTR (your jars would be on the track)
e. Deploy the external library DC so that the Jars are deployed on the portal server.
f. Add the public parts of this External Library DC under used DCs of your development component.
g. Add this external library under library references of your project.
h. Build and deploy.
i. Now try activating your activity.
Use the following link to know how to execute these steps.

Java EE Tutorial - problem with the example Bookstore

Hi,
I've been working few days on a problem running the Bookstore example from the Java EE Tutorial. When I run the application, I'm redirected from the servlet BookStoreServlet to errorpage.html with the following message: The application is unavailable. Please try later. The tutorial troubleshooting reads: ... a servlet cant retrieve the web context attribute representing the bookstore. This will occur if the database server hasnt been started. But the database server is running (I'm running Derby bundled into NetBeans 6.5). The Glassfish admin console reads:
StandardWrapperValve[BookStoreServlet]: PWC1406: Servlet.service() for servlet BookStoreServlet threw exception

Please help, I really need to run the examples.
Best regards,
Rene Puchinger

I solved the problem running the command that is correctly explained in the page 97 of the tutorial:
Ant create-tables
My mistake was that until that day, I was believing that I could do everything inside Netbeans.
For this you explicitly need to use ant.
Then I got some error which I solved fixing the file
C:\Java\JavaEETutorial5\examples\bp-project\ build.properties
( like set correctly the path to the server and so on)

XML Form Builder-Problem with the save button

Hi All,
I created a project in XML Form Builder.
I included a button "Save" in my project.
All is working fine when i preview my project in XML Form Builder.
The problem is when i run my project with iview.
I suppose the form to save my input and then to be closed but
unfortunately it did not.
I don't know where the problem is as in the XML Form Builder everything seems ok.
Thank you for your help!
Regards,
Ari

Hi Carsten,
Thank you for your help.
There is no javascript error in the form.
In the status bar when i have my mouse over the button i can see "javaxcript:HrefSubmit('save',"");"
And when push the button "Transering Data..."
I created the form in the Xml Form Builder and in preview there the project works.
What do you mean "Did you access your Form using the KM Admin Explorer via a comman?"
How can i have acess there?
I appreciate you help!
Regards,
Ari

Problem with bookstore1 example in J2EE 5 tutorial

Hi everyone. I'm pretty experienced with J2EE but new to the 1.5 version. I'm using the Sun One Server 9.1 and the ant tools. This is referring to the samples in the J2EE 1.5 tutorial. I set my build.properties file and tried to build bookstore1 using ant and then ant deploy. I get the following error.
Deploying application in domain failed; Error loading deployment descriptors for module [bookstore1] -- javax.annotation.Resource.authenticationType()Ljavax/annotation/Resource$AuthenticationType;at com.sun.enterprise.deployment.annotation.AnnotationInfo@4b35d5 Error loading deployment descriptors for module [bookstore1] -- javax.annotation.Resource.authenticationType()Ljavax/annotation/Resource$AuthenticationType;at com.sun.enterprise.deployment.annotation.AnnotationInfo@4b35d5
This error is wracking my brain. If any one could help me with this, I'd really appreciate it.

Well, i haven't checked this forum for a while so by now you've probably figured this out. Anyway, there is a build.properties.sample file in the $JAVA_TUTORIAL_HOME\examples\bp-project directroy. Rename that file to build.properties. Open it and look at it. Really, it should already be filled out. There is a property in there like this
javaee.server.passwordfile=${javaee.tutorial.home}/examples/common/admin-password.txtYou have to go to this admin-password.txt file and set the password to your app server. In mine, I have
AS_ADMIN_PASSWORD=passwordNow, you can go to any web project and run asant. Us asant (which stands for Application Server ant). You can use ant, but using asant will ensure your using the right version. Also be sure your using Java Application Server 9 and the asant that comes with it.
