Accessing CPU clocks or system timers through java

Hello ,
We want to get access to system CPU clock which should run even when the system is shutdown. Additionally first time it should be set by a java program and it should run for some specific days amount of time . It should remain unaffected if the external user changes the system time displayed. Can it be possible through any means in java ???

Hi
we are designing an application which should run only for 15 consecutive days,we dont want the user to hack it by any means by changing the system time,so we want to have access to the system time which works with the help of battery backup or some other means by which we can detect whether the user has altered the system time.

I want to create a setup file for my application. before setup my application i have to check whether the system has JVM or not. If its not then i have to install JVM first and then my application. so i need to access system registry. please give me a solution for this.
Thanks in advance

I don't know how to access the registry
by using java code. You can't, without using a native interface (JNI type) library.
This is one, there are others, do a Google search:

Hi Srini,
This is just a suggestion, but try entering the following commands (in your SQL*Plus session) before executing your stored procedure:
set serveroutput on size 1000000
exec dbms_java.set_output(1000000)Hope this helps.
Good Luck,
Avi.

Is there any way to get a big system icon through java?

the getSystemIcon() method returns a little icon, perfect for a JTree implementing a file tree. I'd like to be able to get the big version of it.
how to do?

I think they mean javax.swing.filechooser.FileSystemView getSystemIcon but I don't believe anything more is possible built in to the API then that.

PI 7.1 Access to Dynamic Configuration through Java Class

My Current scenario involves IDCO -> FILE communications in PI 7.1 using XSL where the file name is dynamic.
I have attempted calling a Java Class from XSL with the use SAPXMLTOOL kit option set in the adaptor and it works but I need to be able to call the transform method
public void transform(TransformationInput arg0, TransformationOutput arg1)
from XSL so I can access the message and update the File Name via Dynamic Configuration.
Whilst I can call a static class with in the object I can not call transform with the correct arguments (arg0, arg1). I need access to arg0 (payload) to set/figure out the filename. I can calculate the filename in XSL and pass it to the Java but in a static method it is useless as it need to access the arg0 which is a object and obviously non-static context.
Is this possible ? How do I get access to Dynamic Configuration from XSL through Java in 7.1 ?
I have successfully called a static method but that is no help.
Thanks in advance.

Suraj,
Unfortunately you link isnt operational but thankyou anyway, I have managed to call as Java class as per my original post, but a static method does not allow me to get a handle to the Dynamic Configuration Variables in the message.
It seems importing the 7.0 LIBS may be an option and Im not entirely sure I have that option.
It certainly isnt possible to use the JDK5 XML implementation to even call a static method on an Java OBJ from XSL (obviously the USE SAPXMLTOOLKIT option is there for a reason).
I think and again I could be wrong but direct access via XSLT..
LINK:http://help.sap.com/saphelp_nwpi71/helpdata/EN/e2/e13fcd80fe47768df001a558ed10b6/frameset.htm
Is what Im looking for, I shall report back success or failure but the doco seems to fit the bill. Im not sure why I wanted to instatiate a sperate Java class when it can all exist in the XSLT.

How to access XI_AF_MSG table in Composite Application Framework Java Code

Hi Experts,
I've no knowledge about PI. In one of my projects, I need access the XI_AF_MSG table of PI through java code in a composite application.
How do I access this table? I've searched this forum for this query but the replies say that any SQL editor can be used to access XI_AF_MSG table. But my question is; How do I get the login details of the database? In the first place, how do I access the underlying database layer of PI? Is there any JAR file which can be used to make the connection?
It would be of great help if any expert on this can give me a detailed reply.
Thanks a lot in advance.
Best Regards,
Nitin

Hi Nitin,
The AFW runs on the J2EE Engine, so this table is in the Java Schema of the database and thus not visible in the ABAP stack. I guess you can use any tool your database provider offers for looking at table contents (e.g. SQLPlus).
Regarding how to access the table please contact you basis administrator they will have access to the tables as they have j2ee_admin login ids and pwds.

Program to Set System Time in Java

Is there any way to set the system time through Java. If there is can you help me some information.
Regards,
Shivakumar Thota

Hey Hey,
You could run Runtime.exec() to execute a command such as VBScipt to do it.
Other than that you may have to take a look at Java Native Interface(JNI) that will basically take control of doing anything you need.
Also, You may want to post this in "New To Java" or some other forum other than Java Web Start. You'll get more people to help ya.
Hope this helped,

[nForce] Current cpu clock has changed

My cpu was running ok, the bios showing Current CPU Clock 1833MHz, System Performance [Auto] and cPU FSB Clock [100MHz]. Some time ago I had a problem getting the AGP card to work, when I did I took a digitial photo of all the BIOS settings when the PD worked - thats how I know the above setting. A couple of day ago I noticed that the cpu was running cool and performance wasn't as good as it should be so I checked under "System Properties" and that shows an Athlon 1.09GHz. I've tried clearing CMOS and setting BIOS defaults (read on this forum somewhere). I've also tried FSB at 133, 166 and 200 but still only seem to report an Athlon 1.09GHz. Any suggestions.
MSI K7N2G-ILSR

set perfomance to manual. set FSB:CPU in ration 1:1 set correct FSB to your CPU which must be 166. Frequency must be 1833MHz(PR 2500+).

Help on accessing tables available in SAP through Java

Hi All
I want to access some tables available in SAP through my Java program. Do I have to write any code for database connectivity or straightaway I can write SQL statements in my Java code?
Can anyone please suggest the sample code for this?
Thanks in Advance,
Vijay.

Hi,
You need JCO(Java Connector)
Check this sample code.
import com.sap.mw.jco.*;
public class JcoTest {
private static JCO.Client theConnection;
private static IRepository theRepository;
public static void main(String[] args) {
createConnection();
retrieveRepository();
try {
JCO.Function function = getFunction("RFC_READ_TABLE");
JCO.ParameterList listParams = function.getImportParameterList();
listParams.setValue("BSAUTHORS", "QUERY_TABLE");
theConnection.execute(function);
JCO.Table tableList = function.getTableParameterList().getTable("DATA");
if (tableList.getNumRows() > 0) {
   do {
    for (JCO.FieldIterator fI = tableList.fields();
      fI.hasMoreElements();)
      JCO.Field tabField = fI.nextField();
      System.out.println(tabField.getName()
           + ":t" +
           tabField.getString());
     System.out.println("n");
   while (tableList.nextRow() == true);
catch (Exception ex) {
   ex.printStackTrace();
private static void createConnection() {
try {
   theConnection = JCO.createClient("000", "DDIC", "minisap", "en", "sincgo", "00");
   theConnection.connect();
catch (Exception ex) {
   System.out.println("Failed to connect to SAP system");
private static void retrieveRepository() {
try {
   theRepository = new JCO.Repository("saprep", theConnection);
catch (Exception ex)
   System.out.println("failed to retrieve repository");
public static JCO.Function getFunction(String name) {
    try {
         return theRepository.getFunctionTemplate(name.toUpperCase()).getFunction();
    catch (Exception ex) {
     ex.printStackTrace();
      return null;

Connecting to R/3 System through Java Web Dynpro forms.

Hi,
I have a requirement in which I have to send data to R/3
from Java Web Dynpro screens.
I will design the Java Web Dynpro screens and write a RFC Model.
I will write a RFC in se37 which will connect to the RFC Model.
Before creating the RFC in se37, I will create ztables in se11.
I will write a ABAP Report to see that all data enters the ztables.
I need some guidance with regard to this.
Do, the RFC Model have the access of the ECC(R/3) System.
What are tasks to be told the Basis guy so, that RFC being called from through Java Web Dynpro?
Please provide me some documents with regards to this scenario.
Regards
Neha Singh

Hi Neha,
The steps you provided is clear enough to connect to a R/3 system through the WD forms.
On creating the model you need to give two inputs such as
logical system name for model instance
logical system name for RFC metadata
there will be 2 default values, also you can create your own JCOs in the <servername>:<port>/devinf of the server or u can ask your basis team also.
Before creating the JCO , the SLD (System Landscape Directory) needs to be configures, that your basis team will know.
other than that once you create the functional module in se37 make it RFC enabled , and once you import the RFC model , you can give your ECC system user name and password and search for RFC you have created from the list of RFC.
Regards,
Sam Charles J.
