Create independent requirements in SAP R/3 using Java Connectors

Dear Experts,
I am an Developer and have this requirement .
My part is to deliver a program [an EXE program] that can read an input file and create independent requirements in SAP R/3 accordingly using these function Modules.
One thing that is very important to Notice is that, to keep requirements synchronized in SAP with an external requirements plan[flat file] I will have to:
1) Read the existing requirements for a material/plant combination using the BAPI_REQUIREMENTS_GETDETAIL from the Java program and
2.) Update any existing requirements that dont match the external requirements source through BAPI_REQUIREMENTS_CHANGE.
3.) Create new requirements using BAPI_REQUIREMENTS_CREATE.
Please help me how do I go about this.
Your Help will be appreciated .

Hi
I not understand your question.
¿Need the steps to make the exe program?
1.     Make the JCO communication between Java and SAP R/3
2.     read the flat file and use BAPI_REQUIREMENTS_GET to display detail for planned independent Requirements.
3.     Update any existing requirements that dont match the external requirements source through BAPI_REQUIREMENTS_CHANGE
4.     Create new requirements using BAPI_REQUIREMENTS_CREATE.
5.     call BAPI_TRANSACTION_COMMIT
Important message of SAP documentation for BAPI_REQUIREMENT_CREATE > Caution: Method is obsolete as of Release 40A!
Try reading the documentation for this BAPI.

How to create interactive map in SAP Visual Business using SAP UI5 SDK

Hi,
Please tell me,
How to create interactive map in SAP Visual Business using SAP UI5 SDK.
Is it possible to create interactive map using VB Control in SAP UI5 SDK..?
if possible please any one let me know.

Hi folks, one question:
We have our development close moved and now it is earlier than originally planned.
That means that we maybe can't finish our convenient API and you have to wait till we will release it - early 2015 is planned.
But there is another option:
Currently we have a API based on json. The developer has to create json and to transfer it to the Visual Business control.
This interface is more used as a low level API and we are developing on top the more convenient one. So all the features are the same.
It will stay stable & compatible in the future and you can build on it.
Do you want to use this interface?
Then I will publish the documentation.
Let me know.
Thanks

Creating desktop shorcut and start menu entry using java

Hey Guys
I have a requirement in which i will need to install a desktop application .After installing i will need to created desktop shortcut icon and start menu entries.
I have worked very less with desktop application and hence i need some help in figuring out how to achieve this.
Any help would be greatly appreciated.
Thanks
Chetan

George ,
Thanks for ur reply .Just to give you some background on this one.
We were using Java web start to do the installation and it used to take care of creating the shortcut icon and start menu entries.
The problem is that we have decided to move away from java web start and use the exe approach of installing .We wrap our JAR files in an exe and make use of Launch4j. See - launch4j.sourceforge.net/ .
The launch4j software helps in bundling all our JARs into an exe and when the exe is clicked it invokes a class present in our JAR file .However it does not create any icons because of which we will need to do that manually.
Any ideas on this?
Thanks
Chetan

Can I create MS-Word files or PDF files using java

We are developnig a web based application for banks and in this at some point we need to provide reports to the Banks for downloading and printing . Now I do not want to make simple .txt files ,I wan to use some sophsticated file format which look nice.
So is it possible for the server to create files in say .doc format or in say PDF format etc which the banks may download and print.
I am using java servlets and jsp as front end and java classes in middle tier and oracle is my database.

Please try this code:
import god.java.pdf.*;
PDFWriter pw=new PDFWriter(new OutputFile(new String("sample.pdf")));
pw.print("This is your text.");
pw.close();

How will i create physical directory in oracle pl/sql using java

how will i create physical directory in oracle pl/sql using java

This is, I suspect, related to Re: how will i overcome from this error java.io.IOException. Quite why you felt the need to have two partial threads instead of one thread with a complete set of information is beyond me. Perhaps this muddled thinking is indicative....
Anyway, if I was looking to do this particular task in Java I would look to using the specific command File.mkdir() rather than trying to use a generic exec approach.

BOE SAP integration kit issue - Java connector

I am trying to install BO applications on one of the TPC system (TPC5).
BOE XI 3.1 Sp3 (using tomcat)
SAP Integration Kit SP3 win for IA32bit
For java connector i am using files from sapjco-ntintel-2.1.8 (tried using 2.1.9 and 3.0.5 as well)
BOE installation goes thru fine and Java Info view, CMC all works fine
Now when i try installing the integration kit it gives some problem during identifying the java connector
I did save the sapjco.jar file in C:\program files\business object\tomcat55\shared\lib folder as specified in all installation guides
But still it do not identify it properly and says Java infoview might not work properly.
So i still go ahead and see that Java infoview doesn't work. Neither does the CMC.
Though WebI still works fine and can acces data from SAP BI system properly.
I have looked a lot into forums but couldnt find the reason other than placing librfc32.dll, sapjcorfc.dll and sapjco.jar files in respective places.
(i did register the librfc32.dll using regsvr32 librfc32.dll)
I have tried installing and uninstalling this couple of times.
Also when i only uninstall the integration kit. Somehow the CMS server stops and doesnt start again.
and hence have to uninstall BOE as well. Any trick here will help too.
Could it be the SP3 version of BOE or SP3 version of the integration kit?
Or
Could I be missing some step?
Thanks
Ritesh

Hi Ingo,
I have installed it couple of times and since it didnt work I uninstalled it along with BOE and Crystal reports.
Now, I again installed only BOE and crystal reports.
I did try installing the integration kit but since it donot recognizes the Tomcat Web application server in the 3rd step
I donot proceed ahead.
The SAP Java connector file (sapjco.jar) is placed in a folder
C:\Program Files\Business Object\Tomcat55\shared\lib\
When running the integration kit, in the 3rd step when is asks for configuring the tomcat server it
has a default path of
C:\Program Files\Business Object\Tomcat55\
On clicking next it says files not found.
So i change the path to
C:\Program Files\Business Object\Tomcat55\shared\lib\
On clicking next it brings up a pop message saying
No Compatible Web Server found.
I stop there and exit the setup process
I tried verifying the version of librfc32.dll which is installed along with the installation of the SAP GUI (710)
Then for the SAP connector i download it from the service.sap.com\connectors the 2.1.9 version for 32bit
And copy sapjco.jar file into the above mentioned folder and
copy sapjcorfc.dll into C:\windows\system32 folder.
And then run the integration kit.
Thanks

Help Required Regarding - SAP Job names using R3 data flows

We are calling a set of SAP Jobs using R3 data flows in data services. When ever a job fails we first kill the active SAP jobs by logging into SAP and then restarting the Jobs.
There are about 100 odd SAP jobs that we call using these Data services Jobs so we wanted to kill the jobs using a reusable code on the SAP side by passing the Job name just before every R3 flows just incase its still in active status.
So wanted to know if there are any short cuts to retrive the set of associated SAP job names because it will be a tedious process to hardcode the SAP job names and pass them as parameters for all the 100 + SAP job names in the custom defined resuable code.
Any help or advice on this please !!

The program is not meeting the expectations
and the problem is due to reflection.Do we know this for certain?
... my application gets the class name, field name
etc. from an XML file so i don't know their method names
beforehand .
Now since every class instance corresponds to a row
in the database and i have to call get and set
methods of each class instance so the performance
keeps on degrading as the number of columns and rows increase .
Can somebody suggest some improvement regarding this
and regarding creating multiple instances of the same object Class.forName() will be using a hash already, so there is probably not much room for improvement.
Class.newInstance() probably does not take significantly more processing than a simple "new Fubar();".
Umpteen reflective method invokations (one per column) for each row/instance - Are you saying these are the problem?
You can test this easy enough.
If you comment out the reflective method invocations and leave the rest of your code untouched,
does your application processing speed up significantly?

Hardware requirements for SAP ERP 2005 using ECC 6.0

Hello everyone,
i am already new and need information about the min. hardware requirements for a SAP ERP 2k5 System using ECC 6.0 with IDES 7.10.
I read the Master Guides about ERP, but i am not even more clever than before.
The OS is MS Windows 2k3 Server EE.
The last information i had from another one to this configuration is:
1 dual-core cpu (? Ghz)
4-6 GB RAM
300 GB HDD
Does it fit? Can anyone help me out?
Thanks in advance.

Hi,
IDES 7.10?!?
If it's an IDES system you want to set up, HDD space may be the bottleneck. It's sufficient for installation, but you may run out of disk space since note <a href="https://service.sap.com/sap/support/notes/1013391">1013391</a> states
Hardware Requirement
                 MS-SQL ORACLE   MaxDB   DB2 Win/Unix AS/400
DB size (GB):    160     220      220          160       280
Since IDES is for education and training purposes only the rest should be sufficient.
I'm running an ERP 6.0 IDES system (32 bit) on a single core, 3.2 GHz, 4 GB RAM, 250 GB System and 500 GB SAP/DB HDD with pretty good response time.

Hi,
I'm not sure, but I believe the 'code' argument should end with '.class'. However, your implementation of displaying a Java applet seems ok, the error is within the applet's Jar file
Anyway, have a look at http://download.oracle.com/javase/1,5.0/docs/guide/plugin/developer_guide/using_tags.html#applet and http://www.w3.org/TR/html401/struct/objects.html#h-13.4 on how to use the <applet> tag
As a test, you could try and create a local HTML document on your local desktop, including the applet. I would suspect you will receive the same error in your Java console
I believe the only option is to recompile your Java applet (if possible at all) against a newer JDK (1.4 and up)

How to create a ms-access database at runtime using java

hi, this is ravi kiran,
i have a situation where i need to create a new ms-access database with one table in it at runtime(when user clicks on some button).
i have been searching many sites to know how to do this in java, but i didnot find any thing useful.
plz tell me how to do this in java.
plz help me, its urgent
thanx in advance.

Here's how I did it. Research does help, but sometimes looking at others code does too... You do have to have a dummy file that you made with access though. You can't just make a file file.mdb (it will be corrupt)
     public void createDatabase(String database) throws SQLException{
          try{
               // This file needs to have been created with MS Access
               File dbfile = new File(this.dataBaseDir + "dummy.mdb");
               // This is the new database file being made
               File newFile = new File(this.dataBaseDir + database + ".mdb");
               // Copy all bytes from dummy file to new DB file.
               FileInputStream instream = new FileInputStream(dbfile);
               FileOutputStream ostream = new FileOutputStream(newFile);
               int numBytes = instream.available();
               byte inBytes[] = new byte[numBytes];
               instream.read(inBytes, 0, numBytes);
               ostream.write(inBytes, 0, numBytes);
          catch(FileNotFoundException e) { e.printStackTrace();}
          catch(IOException e) { e.printStackTrace();}
          if(DEBUG) System.out.println("creating the " + database + " database");
     }

I Can't create and add en entry in Ldap using Java

I'm pretty new to LDAP programming, and I have been trying to create and add an entry to a directory using the code sample provided in the JNDI tutorial, but for some reasons, I didn't manage.

    myAttrs.put("mail",mail);
}as I said, I can add the new entry using an LDIF file "new.txt" that looks like this:
dn:cn=Hamido Saddo,ou=People,o=JNDITutorial,dc=img,dc=org
cn:Hamido Saddo
mail:[email protected]
telephonenumber:3838393038703
sn:hamido
objectclass:top
objectclass:person
objectclass:organizationalPerson
objectclass:inetOrgPersonusing the following command:
ldapadd -D "cn=ldap_admin,o=JNDITutorial,dc=org,dc=img" -W -f new.txtand eveything works
but when i try with the java, i get the following error:
javax.naming.directory.SchemaViolationException: [LDAP: error code 65 - entry has no objectClass attribute]
so, can anyone help me please !!!

uncomment these lines
/*objectClass.add("organizationalPerson");
objectClass.add("person");
objectClass.add("top");*/
you need all of them to add successfully
your LDIF has all the four lines
objectclass:top
objectclass:person
objectclass:organizationalPerson
objectclass:inetOrgPerson
hope this helps

Create a file at a Windows Vista using java applets

I have created a java applet which is downloaded to create local file at a Windows Vista PC. The java codes are:
File out = new File("c:/users/test/hkuesd.properties");
FileWriter fw = new FileWriter(out);
PrintWriter pw = new PrintWriter(fw, true);
pw.println("#sample property file");
pw.println("key_path=C:/");
pw.close();
fw.close();
If I turn off "Users Account Control" under "Control Panel" --> "User Accounts", the file "hkuesd.properties" is created at c:\users\test and can be found using windows explorer.
However, if I turn on "Users Account Control", I can not find the file "hkuesd.properties" using windows explorer. But the file can be detected if I run another java applet program with the following codes:
File xpdir = new File("c:/users/test/hkuesd.properties");
FileInputStream fis = null;
if (xpdir.exists()) {
try {
fis = new FileInputStream("c:/users/test/hkuesd.properties");
Properties p = new Properties();
p.load(fis);
fis.close();
privateKeyPath = p.getProperty("key_path", "no value");
catch (Exception e) {}
Interestingly, if "Users Account Control" is on and I created the file "c:\users\test\hkuesd.properties" manually, the file creation codes
mentioned above seems to create another "hkuesd.properties" at the same "c:\users\test". The evidence is I run the second java applet program which can detect the one created by the first java applet but not the one I created manually.

I agreed that it is hardly explained in words. I
suggested to write two
simple java applets using the codes and you will see
the effects:
(1) the first applet can create a file
"hkuesd.properties"
(2) cannot find the file using windows explorer to
search the whole drive.
(3) However, can read the content of the file using
second applet.You still haven't address your problem of swallowing exceptions. Your code might be throwing an exception that tells you exactly what the problem is. Change your code to display or log that exception.
