How to set the classloader mode in Netweaver 04s

Hi All,
Can anybody tell me how to set classloader mode in Netweaver 04S?
In websphere , there is direct option you when you select the project through admin console. But I am able to find the place in the netweaver where I can set such mode.
classloader mode such as parentfirst, parent last etc
I want to set the mode parent last.
This is very urgent requirenment.So please let me know if anybody is having any input on this.
Thanks,
Chandan

Hi Siddhesh,
Thanks for replying.
Actually,NW has its own version of jaxrpc related jar files (in <drive>:\usr\sap\J2E\JC02\j2ee\cluster\server0\bin\ext\webservices_lib folder) which are of a older version and are being picked up instead of the jars that are present in my application package. As a result, there are exceptions like:

This problem is solved in websphere as probably because we have classloader configuration set through Admin console.
But just wanted to know does we have such option in NetWeaver? If yes, how to set the classloader mode to parent last.
Or if you know some other solution then let me know.
Thanks,
Chandan

How to set the Data Synchronisation mode for ADF BC component?

Hi All,
How to set the Data Synchronisation mode for ADF BC component
Thanks
Raghavendra

Can you clarify what you mean by the data synchronization mode?
If you mean the Sync Mode, then in 10.1.3 you set this property by:
1. Selecting your DataBindings.cpx file
2. Expanding the "Data Control Usages" section in the structure window
3. Selecting the ADFBC-based data control
4. Setting the "syncMode" property in the property inspector.

How to set the full screen mode using setClip method

hi all,
how to set the full screen mode using setClip in that softkeys should not be used insteat on that need to create a own softkeys using commands.
thanks & regards
Bala.

In CS5 there are changes made to how the screen mode is reported. In CS3-CS5 the screen mode has a corresponding number. So for instance if the ScreenMode is set to "Preview Off" and you ask indesign CS3 or CS4 to display the screen mode, it will report "1936552047", while in CS5 it will report "PREVIEW_OFF".
try executing this simple command in respectively CS3, CS4 and CS5 and you will see what I am talking about:
alert(app.activeWindow.screenMode);
there is no difference if you do:
alert(app.activeDocument.layoutWindows[0].screenMode);
The CS5 solution is rather awkward to work with, unless I am missing something? PREVIEW_OFF is not a string, nor is it a number.
Example - doing:
myScreenMode=app.activeDocument.layoutWindows[0].screenMode;
and then trying to reset screenMode by something like:
app.activeDocument.layoutWindows[0].screenMode= myScreenMode
does not work in CS5 of course. It will throw an error. Neither will this line work:
app.activeDocument.layoutWindows[0].screenMode=ScreenModeOptions.myScreenMode;
Any way of working around this?

How to set pre conditions to set the run mode to skip or normal?

Could you please let me know how can I set a precondition based on a local variable so when the variable is 1 I can skip a test or when it is zero I programatically set the run mode to normal.
Thanks

I have a case where I use the Pre-Condition to skip some steps (subsequence call) for a specific test) if that test has run successfully already.
This is handled in a 'SequenceFilePostStep", thus the "RunState.Caller....".
The Precondition is set to 'False' so it won't run.
'Set the Precondition on the next step to "False 'Remove" (The remove is to indicate that it will be removed later so it's not saved in the sequence file.)
Locals.sPreviousPrecondition1 =RunState.Caller.Sequence.Main[RunState.Caller.RunState.NextStepIndex].Precondition,
RunState.Caller.Sequence.Main[RunState.Caller.RunState.NextStepIndex].Precondition ="False 'Remove"& Locals.sPreviousPrecondition1
The "False 'Remove" needs to be removed later, or it will be saved in the file and remain. This is accomplished later with:
'Need to copy the contents to a Local variable, manipulate it to remove the "False 'Remove" string then re-assign back into the Precondtion
Locals.sPreviousPrecondition1 = RunState.Caller.Sequence.Main[RunState.Caller.RunState.PreviousStepIndex].Precondition,
Locals.sPreviousPrecondition1 = SearchAndReplace(Locals.sPreviousPrecondition1,"False 'Remove","",0),
RunState.Caller.Sequence.Main[RunState.Caller.RunState.PreviousStepIndex].Precondition =Locals.sPreviousPrecondition1

Sending image sequence job to compressor in command line : how to set the framerate?

Hello,
In Compressor, when you import a image sequence, it's possible to set the framerate and add an audio file before choosing a preset and lauching the encoding task.
I want to dlo the same thing with command line. I know how to send a compressor job with command line, but no how to add theses settings.
In the compressor command line help, we've got this :
Job Info: Used when submitting individual source files. Following parameters are repeated to enter multiple job targets in a batch
          -jobpath <url> -- url to source file.
                                           -- In case of Image Sequence, URL should be a file URL pointing to directory with image sequence.
                                           -- Additional parameters may be specified to set frameRate (e.g. frameRate=29.97) and audio file (e.g. audio=/usr/me/myaudiofile.mov).
So there are also framerate and audio parameters in command line but i've no idea how to write the command line with theses parameters
Here is an example of command line for Compressor (by Apple) :
./Compressor ‑clusterid tcp://127.0.0.1:51737 ‑batchname myBatch ‑jobpath /Volumes/Source/ShortClips/NTSC24p.mov ‑settingpath /Users/stomper10/Library/Application\ Support/Compressor/PhotoJPEG.setting ‑destinationpath /Users/machinename/Movies/myDestinationFilename.mov.
Thank you for your help!

You can see in the command sh running-config command
show running-config : Displays the current access point operating configuration
Use the guest-mode SSID configuration mode command to configure the radio interface (for the specified SSID) to support guest mode. Use the no form of the command to disable the guest mode.
[no] guest-mode .
Here is the guideline for usage
The access point can have one guest-mode SSID or none at all. The guest-mode SSID is used in beacon frames and response frames to probe requests that specify the empty or wildcard SSID. If no guest-mode SSID exists, the beacon contains no SSID and probe requests with the wildcard SSID are ignored. Disabling the guest mode makes the networks slightly more secure. Enabling the guest mode helps clients that passively scan (do not transmit) associate with the access point. It also allows clients configured without a SSID to associate.
Examples
This example shows how to set the wireless LAN for the specified SSID into guest mode:
AP(config-if-ssid)# guest-mode
This example shows how to reset the guest-mode parameter to default values:
AP(config-if-ssid)# no guest-mode

How to set the classpath in CVM?

Hi everybody,
experimenting with the J2ME Personal Profile Runtime Environment on a Linux PC I wonder how to set the classpath. The command line options only allow me to set the bootclasspath.
My original problems deals with determining the codebase for a class that is contained in a jar.
1) If I put this jar into the bootclasspath, that class is found and can be loaded, but the codebase (retrieved using class.getProtectionDomain().getCodeSource) is NULL.
2) If I put it into the classpath by using the command line option -Djava.class.path=... the class cannot be found by the ClassLoader.
3) If I put the jar into both, the classpath and the bootclasspath, the latter one is applied and result 1) shows up.
Any idea how to work around this?

How to set the oracle oci8 driver?

hello all:
I've set up the oracle thin driver and it works. but when I change to
oci8.it don't work
below is config and errors:
<JDBCConnectionPool DriverName="oracle.jdbc.driver.OracleDriver"
InitialCapacity="5" LoginDelaySeconds="5" MaxCapacity="15"
Name="ocipool"
Properties="user=yanji;password=yanji"
Targets="myserver" URL="jdbc:oracle:oci8:@pg01"/>
Could not load 'oracle.jdbc.driver.OracleDriver
If this is a type-4 JDBC driver, it could occur if the JDBC
driver is not in the system CLASSPATH.
If this is a type-2 JDBC driver, it may also indicate that
the Driver native layers(DBMS client lib or driver DLL)
have not been installed properly on your system
or in your PATH environment variable.
This is most likely caused by one of the following:
1. The native layer SO, SL, or DLL could not be found.
2. The file permissions on the native layer SO, SL, or DLL
have not been set properly.
3. The native layer SO, SL, or DLL exists, but is either
invalid or corrupted.
For more information, read the installation documentation
for your JDBC Driver, available from:

Hello, Jenny I am glad you found your resolution. I too am having problems isung

RefreshMinutes="0" Targets="portalServer"
TestTableName="WIP_TABLE" URL="jdbc:oracle:oci8:@servername"/>
My classpath sets my classes12.zip file first. My path sets %WEBLOGIC_HOME%\bin\oci817_8
and %WLCS_ORACLE_HOME%\bin.
Am I setting the right dll and protocol in my .dll? Where can I find documentation
on these properties definitions?

Its not CLASS_PATH it should be CLASSPATH.
when you say oracle\bin and oracle\lib , on what driver is the oracle
folder?I meant to say 'on what drive' not 'on what driver'
you have to specify the full path.
post your startup script here.

1. Dont copy this file oci8jdbc.dll, to bin folder. Make sure
you
place
<oracle_home>\lib in your PATH before starting the server. Make
sure
your
ORACLE_HOME environment varable is set to <oracle_home> folder.
eg. set ORACLE_HOME=c:\ora816 before starting the server.
so you must have done something like
set ORACLE_HOME=c:\ora816
set PATH=%ORACLE_HOME%\bin;%ORACLE_HOME%\lib;%PATH%
2. double check if you set your CLASSPATH something like this,
CLASSPATH=%ORACLE_HOME%\jdbc\lib\classes12.zip;%CLASSPATH%
in the server startup script just before starting the server.
3. start the server the connection pool should work.

my weblogic version is 6.1 and oracle is 8.1.6 .
why the thin driver is ok but the oci driver can not work?
I logined in the oracle website and look for the jdbc.but I find
that
jdbc
all provide for jdk1.2 or jdk1.1. because the weblogic6.1 based
jdk1.3.
I
think i can not use those drivers.
I think my oracle driver is ok,because i installed the jboss and
bas4.5
in
my computer. they all can use oci8 driver properly.and they all
based
jdk1.3.
by the way. I 've tryed added the oracle\bin path inStartWeblogic.cmd,

To use oracle oci8 driver:
You should have classes12.zip in weblogic classpath.
You should have ocijdbc8.dll in your weblogic path..
You can download ocijdbc8.dll from oracle website.

If this is a type-2 JDBC driver, it may also indicate that

How to set the debug port for Eclipse for OracleAS 10g Enterprise

Hello All,
I am using OracleAS 10g Enterprise, and using dcmctl to startup the server.
But i do not know how to set the debug port in the startup script for debugging with Eclipse.
I have tried to add the following options to the dcmctl.bat, but still failed:
-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=4000
i.e in the dcmctl.bat script:
set jvmargs=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=4000
set ex=%ohome%\jdk\bin\java -Djava.net.preferIPv4Stack=true %jvmargs%
Do anyone know how to configure the debug port setting?
Thank you for your great help!.

Hi, have you double checked that your oc4j is started with Sun's JVM or any other JVM that recognizes the kind of remote debug option as above? You can find the JVM used by oc4j in the ORACL_HOME/opmn/conf/opmn.xml.
To double check that your oc4j is started in debug mode, you can test with another remote debugger. Say, with the jdb in sun's jdk jdb -connect com.sun.jdi.SocketAttach:hostname=yourHost,port=4000 (Personally, I also use Jdeveloper or Jswat to double check.) If you can connect with jdb, then you have to check your Eclipse. Can its remote debugger connect to any java application at all?

How to set the JFrame to be Full screen

yup.. how to set the JFrame to be Full screen mode??

Hi,
You can get the current size of desktop and resize your application to match it.
//Get desktop screen size
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize()
//Set bounds for main window
setBounds(0, 0, screenSize.width, screenSize.height); Br,

How to set the sampling interval using DAQ device?

Now I have a capacity sensor and a 24 bit DAQ device (http://www.mccdaq.com/usb-data-acquisition/USB-2404-10.aspx).
The DAQ device has the maximum sampling rate of 50kS/s . My question is how to set the interval of data collection. For example, if I set the sampling rate to 2000, in continuous sampling mode, I use DAQmx read.vi in a while loop and set the 'number of samples per channel' to 100. I want to plot these data as a function of time by using a XY graph and also save these data. So I add a 'Mean' function to get the average of the 100 samples per each loop (than means, there are 20 data output per second). But when I set the 'number of samples per channel' much smaller (to get more data per second), there are some problems. It seems that the program cannot read so many data and get the average at a higher frequency. I don't know where the problem is. All in all, how to collect data more frequently?Maybe I didn't express my question clearly. I'll upload a simple program later if necessary. Thanks.
Solved!
Go to Solution.

Another question is in continuous mode, NI DAQmx uses Samples per channel to determine the buffer size. But according to the website you specified, it says if the acquisition is continuous (sample mode on the DAQmx Timing.vi is set to Continuous Samples), NI-DAQmx will allocate a buffer according to the following table. And for sample rate between 100 - 10,000 S/s, the buffer size is 10 kS. So if I set the sample rate to be 5000 S/s, and set the Samples per channel to be 20000, then what exactly the buffer size is? 20 kS or 10 kS?
Thanks.

How to set the SCLK & SDO lines low...

Using a USB-8451 and need to set both the SCLK & SDO lines low as part of a prefix packet that I am sending to a device. how do I do it in LabView?
I can set the SCLK low using the 0 (Idle Low) input to the 8451 Config Property node but am not sure how to set the SDO low as needed.

Yes it is SPI. The device is an MB16024 LED driver from Macroblock.
Are you actually referring to the http://www.mblock.com.tw/products_mbi6024.html? (Note the "I" instead of the "1") Where does it say it's a SPI device? I don't see it saying SPI anywhere on that page. Do you have the actual datasheet? I was unable to find it on their web site.
maybe I cannot use the 8451 for this task?? ...
You can always use bit-banging mode.
