Syetem.getEnv

hi
I need to keep the path of the application location in the System path.
I know i could have use this funcetion but it is deprecated.
the return value of Syetem.getProperties(key) is always null.
How can i get this information?

getenv is deprecated and has been replaced by:
String path = System.getProperty("java.class.path",".");
Assuming you are running this in the same location of the application it will return the path up to the directory that the program resides in.
Not sure thats what you are looking for - but HTH...

ERRORLEVEL and getenv.

I am running a batch file via CVI and I want to check if the command I execute in the batch file is successful. My code is:
sysReturn = system("WifiConfig.bat");
pBatchFileReturn = getenv("ERRORLEVEL");
The problem I am having is that getenv always returns a NULL. My expectation is that the return value is 0. (I also tried modifying the batch file so that the return value is non-zero. For example: exit \b 5.)
I have run the batch file independent from CVI so I know it works. That is, I can run the batch file via the command prompt and check the value of %ERRORCODE% and get the expected value (either 0 or whatever non-zero value I programmed into the batch file.
I used getenv to get other environmental variables from my machine (found in Control Panel ->System -> Advanced System Settings -> Environmental Variables). I did not see ERRORLEVEL explicitly listed, but it obviously exists since I can get its value from the command prompt.
Any thoughts?
Thanks.

I tried putting CVI in console mode - no luck. I also tried the "GetEnvironmentVariable" function from the winapi library. Using this funciton I don't get a value for ERRORLEVEL and I was able to check the function "GetLastError" to see what when wrong. The error I get back is ERROR_ENVVAR_NOT_FOUND.
I know I can create my own environment varibable and manipulate it using "setx" in the batch file but the value change does not take effect until I restart my computer.
I had come across the MSDN blog post you suggested before. I've read it multiple times to try to compare it to my experience. It seems like ERRORLEVEL (the environment variable) only(??) exists in the context of a command prompt window. I tried his script:
rem this next command sets the error level to zero
@echo off
CMD /C EXIT 0
set ERRORLEVEL=1
if ERRORLEVEL 1 echo Does this print?
echo %ERRORLEVEL%
In a new command prompt window if I execute "echo %ERRORLEVEL" I get a 0. After running the script (which outputsa a 1 to the screen), executing "echo %ERRORLEVEL" returns a 1. Starting over with a new command prompt and running "echo %ERRORLEVEL" I get a 0 again.
I could create a custom environment variable that was updated without having to reset my computer, that should be an acceptable approach.

Unable to find JVMDI interface - GetEnv retruining JNI_EVERSION

I'm building a debug agent using jrockit 1.4.2_11 (windows XP). However, my debug agent doesn't seem to be able to find jvmdi version 1_3 (or any previous version, such as 1_2, 1_1 or even 1) in that VM.
For example, the initialization call
(*jvm)->GetEnv(jvm, &jvmdi, JVMDI_VERSION_1) is returning the error JNI_EVERSION.
Any suggestions?

Later versions of JRockit does not support JVMDI. Please use JVMTI instead (yes, JVMTI is supported on our later 1.4.2 versions).

NullPointerException at getenv

Hi, I'm getting the following NPE when calling System.getenv:
java.lang.NullPointerException
        at java.lang.ProcessEnvironment$Variable.valueOfQueryOnly(Unknown Source)
        at java.lang.ProcessEnvironment$Variable.valueOfQueryOnly(Unknown Source)
        at java.lang.ProcessEnvironment$StringEnvironment.get(Unknown Source)
        at java.lang.ProcessEnvironment$StringEnvironment.get(Unknown Source)
        at java.util.Collections$UnmodifiableMap.get(Unknown Source)
        at java.lang.ProcessEnvironment.getenv(Unknown Source)
        at java.lang.System.getenv(Unknown Source)It's strange because all goes well when running it from Eclipse, but it fails when calling java from the command line.
The exception above is raised within a Java Swing application.
Thank you for any help!
God bless
Jaime

The difference between Eclipse and the command line was that Eclipse uses its own compiled classes, whereas the java command from the shell used the built jars.
After recompiling, the problem is gone now; I cannot explain however why it occured in the previous version of the code.
Thank you anyway.
FYI, the stack trace above was only the top, the full stack included calls to the event handling methods of Java Swing, I think nothing interesting.
The getenv method was called from my own code.

Getenv() in C vs getHeader() in servlet?

Dear All,
I can use getenv("HTTP_MSISDN") in C to retrieve the associatede value. However, I can't use req.getHeader("HTTP_MSISDN") to retrieve the same value. What's the difference between getenv() in C and req.getHeader() in Java Servlet?
Star

Hi Heinrich,
Thanks for your quick response!!
Indeed, I am retrieving the MSISDN from Jambala Wap Gateway. It is very strange that I can use getenv() in C to retrieve that value. However, when I use Java Servlet, I can't retrieve it. I tried getHeaderNames(), getCookies(), getAttributeNames(), getQueryString() and even run env to print out all the values. I just can't find it. I don't know what else I can try!

Windows versions & System.getenv();

I have about 3 different versions of windows in my office, and I am working on a time keeping program across the network that will recognize the user by the user name signed on @ their computer. In my Windows 2000 & 2003 environments, I have no problems, but on 98 I keep getting "null\null". i am using System.getenv("COMPUTERNAME") & System.getenv("USERNAME")
Does anyone have insight into the 98 environments to help me out?

If we have windows networking setup, would those values be set, or similar values? Trying to make this as easy as possible for the end user, so any help is appreciated.

Transfer of Shopping Cart (SRM) to Back End Syetem (R/3)

Hi experts,
We have just upgraded to SRM 5.0 with SRM Server 5.5 (SP 0008). We have moved our EBP application from Requisite to CCM. In our old application we have created some customer fields in the shopping Cart and will be moving the data from the shopping cart to Back end (R/3).
In R/3 EXIT SRM_PO is implemented to get the customer fields into Purchase Requisition. Now after moving to SRM 5.0, we are able to reproduce the customer Fields in Shopping Cart. But the data in those customer fields are not moved to Back end (R/3). Earlier BADI ' BBP_CREATE_REQ_BACK ' & ' BBP_CREATE_PO_BACK ' is implemented and in new BADI's
" BBP_CREATE_BE_PO_NEW " & " BBP_CREATE_BE_RQ_NEW " is implemented as well which in turn calls the Old BADI's.
In this situation, i would like to know the following,
1. How the Shopping Cart data is transfered to Back end (R/3). Once we know this we can find whether Customer fields are getting transfered to Back end by Debugging.
2. Is there any RFC or IDocs doing this transfer.
Your replies will certainly help in my further analysis.
Best regards,
Prabahar N.R

HT1752 F*** THAT MY G4 IS OBSOLETE, CAN'T APPLE MOVE MY OLD OPERATING SYETEM TO NEW IMAC??

MY OLD, STILL WORKING MODEL G4 POWER MAC, HAS APPS & DOC'S THAT ARE NOT SUPPORTED
ON MY NEW IMAC. CAN'T APPLE PARTITION MY HARD DRIVE (ON IMAC) AND INSTALL THE OLD OPERATIONG SYSTEM.
SO THAT I CAN AT LEAST READ MY OLD DOC'S.

Try being a bit more specific and maybe you'll get a useful response.
For example what Applications were you using on your on your G4?
You could move the G4 documents over to the new iMac and potentially use them with updated applications and/or replacement applications.
You got 6 years out of your G4 and it will still function within the parameters that it was purchased for... NOT BAD!
BTW: You will be unhappy with your new iMac WELL BEFORE 2018....

How to conduct two inputs two outputs syetem with fuzzy control funtion?

I have two DC motors to control two variable capacitor, and I use HP 8752c network analyzer to look the circuit's resonance frequency and reflection as a feedback control.
The relation between inputs and outputs are nonlinear and they are all correlative with each other. But it still has a trend so that I can tune them by myself. It's time-consuming.
I would like to ask that the fuzzy logic control is suitable for my situation?
The system is time-invariant.
Thanks.

Ale master data scenario integration with non sap syetem i.e seebeyound

hi
we have a business process scenario integrating with non sap system (i.e seebeyound)

a(add)          material1     plant 2
d(delete)       material 3    plant 6
etc
we have upto one million materials assigned to 300 plants
we have to send all the above data to non-sap system (see beyound)
should we go for a custom idoc and setup the rfc configuration for the two sytems.
or can you please help how to go for this scaneriao

this is not one time.it is on daily basis.
please look at this scenario.what i need is how should i go for ale/idoc scenario for this one
Business case for Heiler Part/Plant Interface:
A key function of the Heiler PBC tool is to provide users a choice
between a "Global Catalog View" (e.g. all parts in the catalog) or a
"Local Catalog View" (e.g. the subset of parts in the catalog that have
a Material Master established for the user's plant in SAP). The "Local
Catalog View" is the default condition and encourages users to procure
parts that are on contract for their plant and potentially already
stocked as an inventory item at their plant. Parts that are not in a
user's "Local Catalog View" can only be procured as a spot buy purchase
order, requiring processing by a buyer.
The new Part/Plant interface is required in order for the Heiler PBC
tool to provide this "Local Catalog View" function. The Heiler
Part/Plant table will document what plants in SAP have a Material Master
record established for each part. SAP will maintain the Heiler
Part/Plant table using this interface. When a user performs a part
search in the Heiler PBC tool, the Part/Plant table determines if a part
is included in the user's "Local Catalog View".

Business Syetem

Hi,
what is the exact definition of business system and busniess component in sap pi?
what is the difference ?

Hi Swetha,
Business systems are logical systems which acts as a sender and receiver in PI. we can create multiple business systems under one technical systems. we create business systems in SLD and import in ID if we have the system details.Business system is assigned to software component.
Business Systems - System Landscape Directory - SAP Library
Business Component is also a logical system which acts as sender and receiver in PI.we create business component directly in ID, when we don't have the system details.Business component is not assigned to Software Component Version, so you have to add Service Interfaces manually to it, in order to be able to use them in Sender or Receiver Agreement. Moreover, BC cannot be used in Integration Directory in order to generate Integration Scenario for ESR model - you have to create all objects manually.
