How to separate JAVA from ABAP in BI 7.0

Hello Experts,
we think about a separated BI (ABAP and BI-JAVA) on two servers
during a migration to a new Hardware!
The existing system is a double-stack (BI 7.0).
So we should find out how to do this, how to separate the
Java instanz from the ABAP during the migration.
Does anybody know the right procedure or a "How To Guide"?
Thanks in advance.

How to Call Java from ABAP

Hi all,
I have installed JCO & created the RFC in SAP. i have used below code to test my RFC connection & it's working fine.
But In the below report, where to call the JAVA Program & what code i should use to call java code .
Actually my ABAP requirement is to download a file. Then i need to call JAVA program, inside ABAP, to encrypt the downloaded file. Here, Java program is used to encrypt the file. Now question is, how to call the Java program inside the ABAP code. Please advice with the code sample. Thanks a lot.
REPORT z_jco_test.
PARAMETERS: requtext LIKE sy-lisel.
DATA: echotext LIKE sy-lisel,
      resptext LIKE sy-lisel,
      rfctest TYPE TABLE OF rfctest,
      wa_rfctest TYPE rfctest.
wa_rfctest-rfcdata1 = requtext.
wa_rfctest-rfcdata2 = 'Hello World'.
APPEND wa_rfctest TO rfctest.
CALL FUNCTION 'RFC_PING'
DESTINATION 'JCO'.
CALL FUNCTION 'STFC_CONNECTION'
DESTINATION 'JCO'
EXPORTING
    requtext = requtext
IMPORTING
    echotext = echotext
    resptext = resptext
TABLES
    rfctest = rfctest.
WRITE: 'Echo Text: ', echotext.
WRITE: 'Response Text: ', resptext.
LOOP AT rfctest INTO wa_rfctest.
WRITE: / 'rfcdata1: ', wa_rfctest-rfcdata1.
WRITE: / 'rfcdata2: ', wa_rfctest-rfcdata2.
ENDLOOP.

Hi,
You might accomplish your goal using external operating system commands.
1) Define in SM69 an external command, letu2019s say ZJAVA. This command will execute a script on the operating system, letu2019s call it calljava.sh.
2) In script calljava.sh you just call java, passing some parameters. For example, java $1 $2 $3 $4 $5 $6 $7
3) In your ABAP program you call the ZJAVA external command and pass parameters to it. Of course, one of the parameters must be your Java program name.
CALL FUNCTION 'SXPG_COMMAND_EXECUTE'
    EXPORTING
      commandname                   = l_command
      additional_parameters         = l_param
      trace                         = 'X'
    IMPORTING
      status                        = l_status
      exitcode                      = l_exitcode
    TABLES
      exec_protocol                 = l_exec_protocol_itab

For saving the report you can goto System -> List -> Save -> Local File -> Location where you want to save in your presentation server.
You can also give a option in your selection screen to save the file to Presentation server using FM GUI_DOWNLOAD.
Hope it helps.

Java from ABAP?

Hello!
How can I start (=call) a java program from ABAP? I have only .class and .java files.
Thanks!

Hi,
Using the SAP Java Connector
SAPu2019s new Java middleware, the SAP Java Connector (JCO) allows customers and partners to easily build SAP-enabled components in Java. JCO supports both inbound (Java calls ABAP) and outbound (ABAP calls Java) calls in desktop and server applications.
Sample program
Import statements: Any program using JCO should contain the following import statement:
import com.sap.mw.jco.*;
Otherwise, you have to fully qualify each class and interface which is very inconvenient.
Connecting to SAP
JCO.Client mConnection;
A connection (or session) with SAP is handled by class JCO.Client
try {
mConnection =
JCO.createClient("400", // SAP client
"c3026902", // userid
"********", // password
"EN", // language
"iwdf5020", // host name
"00"); // system number
mConnection.connect();
catch (Exception ex) {
ex.printStackTrace();
System.exit(1);
"A Client object is created via a call to createClient(). You can use a specific application server (as in the above code) or a server group (load balancing)." REFER the JCO Javadoc for the overloaded createClient() method for the latter possibility.
"The Client class's connect () method tries to log on to SAP. If that fails for any reason, an exception is thrown. If the call succeeds, we can now stay connected for as long as we like. When we are done, we can call disconnect () to explicitly log off."
Hope this sample would help you..

Calling external Java from ABAP using JCo?

Does anyone know if one can use JCo to write a server application that can be called from ABAP.
We are presently using JCo to communicate from Java to SAP.
But we need to call an external Java program from within ABAP.
Is this possible?
Thanks for any input.
Fred

Hi Gregor,
I was hoping you would reply to this -- these posted messages had been here for quite sometime now.
Anyway, here's the case. Our Basis team is installing the JCo in our SAP development server. This is our first time to implement this technology, so no one has a clue at all.
Got a couple of questions for you...
1. What do we need the JDK for? Is it mainly for editing, running, and compiling java files (e.g. Example5.java)?
2. Does the JDK need to be installed at the SAP server as well? Or it doesn't matter, as long as the java files will be accessible from where it was installed at?
Thanks for any response!

How to run Java from Firefox Extension using liveconnect?!

Hi, I'm trying to run a very simple java program from a Firefox extension I'm making but I've run into a brickwall and just can't get it to work. I'm a complete beginner in java and don't know much javascript so I've copied and pasted code from around the net to get where I am now. I'm sure I'm just making some stupid error at some step.
In order to work out what I'm misunderstanding/doing wrong I'd be really grateful if someone could show me how to get it to work using a very basic example:
Say I have a .java file taken from the sun pages:
* The HelloWorldApp class implements an application that
* simply displays "Hello World!" to the standard output.
class HelloWorldApp {
    public static void main(String[] args) {
        System.out.println("Hello World!"); //Display the string.
}So I stick it into a jar using:
jar.exe cvfe HelloWorldApp.jar HelloWorldApp.class HelloWorldApp.class
I then place it directly on my C: drive.
In the javascript of my firefox extension I have code copied and pasted from https://developer.mozilla.org/en/Java_in_Firefox_Extensions:
var urlClasz = java.lang.Class.forName("java.net.URL");
var urlArray = java.lang.reflect.Array.newInstance(urlClasz,1);
urlArray[0] = new java.net.URL('file:///C:/HelloWorldApp.jar');
var cl = java.net.URLClassLoader.newInstance(urlArray);
var aClass = java.lang.Class.forName("HelloWorldApp", true, cl);
var aStaticMethod = aClass.getMethod("HelloWorldApp", []);
var greeting = aStaticMethod.invoke(null, []);This seems to start java but then only gives me the error:
"Error: uncaught exception: Error calling method on NPObject! [plugin exception: java.lang.ClassNotFoundException: HelloWorldApp]."
I would be infinitely grateful if someone could show me the code I would use in this situation to run the HelloWorldApp. If I could get it working in this basic situation I'm sure I could work it out from there.
Thank you very, very much!!

By the way, I answered just because nobody did and I have some experience with using java from mozilla javascript.
But I never played with Firefox extensions.
No problem baftos, I understand you might not have all the answers but you've helped loads so far, so thanks a lot! I've found it very difficult to find good documentation on this for a beginner like me.
Adding public did it (although I thought that I'd tried that, oops) so thanks again for that. I may have a couple of other questions just in case you happen to know the answer!
I'd like to send some string arguments to the method I really want to run eg:
public class HelloWorldApp {
public static void sayHello(String[] args)
{code}After googling .forName and .getMethod to see how to pass parameters I've added some code:
{code:java}
var strClass = java.lang.Class.forName("java.lang.String");
var parameters = java.lang.reflect.Array.newInstance(strClass,2);
parameters[0] ="My string argument";
parameters[1] ="3"; // etc...
var argHolder = java.lang.reflect.Array.newInstance(strClass,1);
argHolder[0] = strClass;
var aClass = java.lang.Class.forName("HelloWorldApp", true, cl);
var aStaticMethod = aClass.getMethod("sayHello", argHolder);
var greeting = aStaticMethod.invoke(null, parameters);
{code}What I thought I was doing was creating a java array: argHolder and putting the string class/object thingy?! in it so that getMethod would look for a method called "sayHello" which took a string array as an argument... but apparently not!
This brings me back to square one with a cannot find method with these arguments error:
"Error: uncaught exception: Error calling method on NPObject! [plugin exception: java.lang.IllegalArgumentException: No method found matching name getMethod and arguments [java.lang.String, [Ljava.lang.String;]]."
You don't happen to know how to do this as well do you?!

The only part of Java that is vulnerable to any known threat is the plug-in. As long as you remove it from /Library/Internet Plug-Ins/ you should never have any issues with Java.
As you will note in looking through the various recommended solutions, completely removing Java is difficult and time consuming. You will also be removing some of the files that originally came with Lion, which could possibly damage your OS.

How to disable Java from OS X

Need help as to removing Java from iMac & MacBook-Pro.

There are rumors of another vulnerability that has not yet been fixed. See:
Did Java just fall down again?!
Because of the numerous times that Java vulnerabilities have been discovered and exploited over the last year, I definitely recommend disabling Java in your web browser if at all possible. If you haven't installed Java on Mac OS X 10.8, you don't have Java, so you're safe. However, if you have, you should disable Java in your web browser. That alone is sufficient protection.
Note that running in a non-admin account will not protect you! All that will do is prevent certain types of infection, but a lot of recent Mac malware has used techniques that do not require admin access. Flashback, for example, was fully capable of infecting a standard user account through a Java exploit, without needing the user to do anything at all.
Also, note that there have been some recommendations to use ClickToPlugin to block Java... however, if you read that plugin's site carefully, you'll note that it cannot block all Java applets, and is thus not good protection against Java exploits.

Calling java from abap

Hi Colleauge,
I have a scenario in which i have a program in java. This program expects few parameters and this java program needs to be called from an ABAP program.
Please let me know how can i achieve this.
Thanks & Regards,
Ritwik.

Hi
the concept of Web Dynpro is common for Java as well as SAP.
if you have the SAP Netweaver Developer Studio on your machine you can use it to generate proxies for the Java-SAP calls (and maybe SAP-Java too). This will generate Java classes (which will use JCo) and these classes can be used on your Java system.
You will get help from this concept.

How to extract attachment from ABAP proxy and store in archive link....

Hi Experts,
I need to consume an incoming email attachment in the ABAP Proxy program (POP Mail --> PI --> ABAP Proxy) and then store this file in the IBM content management server through the Archvie Link connection.
Any idea how to implement this piece of code in ABAP?
Regards,
Shobhit

Hi Shobhit
You can get the files from Sender Mail adapter. In proxy implement the method of protocol IF_WSPROTOCOL_ATTACHMENTS as said above.
Archive Link supports HTTP, RFC etc depends on the system you are going to use for archiving. For your case you have IBM server i think you have to do HTTP synchronous. This will be like an interface again for you.
Why are you using ERP system in middle. I think you can directly dump data to IBM server.
Thanks

How to separate UI from code

I usually create front panels that are an interface to read/write parameters via serial modbus.
So the main front panel is composed as follows:
1) on the top, some controls to set COM, modbus address, load/save button, read/write button
2) a textbox control
3) the parameters' list, each parameter has a checkbox (used by write button)
this list is organized in maximum 2 columns, of 16 row each. (If I need more parameters, I use a tab control to group them).
Each row is like:
<caption string description><label><control> <checkbox>
So FOR EVERY instrument/product, I must create these list of parameters.
It's annoying when you have to manage 50 products, each with 32/70 parameters.
So I am trying to abstract this task, and I thought to describe the parameters in a XML file, then create a sort of "generic" UI that load the XML at startup, and populate the UI based on XML information I provide.
How can I do this in Labview if labview natively couples a variable to a UI control element?
I mean: in labview you cannot create a "int x=0;". What you receive is a int variable + its UI control on the front panel!
The entire system has code coupled with front panel.
New VI = front panel + diagram.
I want to separate them, because it's inefficient in my case!
Anybody heard about Windows Presentation Foundation (WPF)?
Any ideas is appreciated, even small simple VIs to test some ideas, because I'm in a dead end.

Never heard of teh WPF, does that rule me out from replying?
I have more ideas than I can post (time limits).
You can create variables in LV! They are the wires. Put a free label on them if you want a name associated with them.
FP controls and indicators are NOT variables, they are graphic widgets that should be thought of as being an I/O device and all interaction with them limited to getting info form the user or updating a display (yes dispaly a COPY of the data that lives in the wire)
I suggest you learn how to use control references. Prior to LV 6i, LV did not have control references and all GUI tricks had to be done in the BD of the GUI VIs. WIth control refeences we can push graphic updates down into sub-VIs. Somewhere arounf LV 8, we got teh ability to do dynamic events which let us push UI operations down into sub-VIs. This image shows waht is a "typical" top-level VI that I delever these days.
