Calling Portal event from ABAP class

Hi Experts,
I need a following clarificatrion, Please help,
1. Is it possible to call a webdynpro method from a normal ABAP class?
2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.
Is there any alternative method which can be used in ABAP having the same functionality.
3. Is there any ways with which we can call portal event from ABAP class?
Thanks,
Shabir

>1. Is it possible to call a webdynpro method from a normal ABAP class?
I wouldn't necessarily recommend this approach. You shouldn't try to trigger events or any of the standard WDDO* methods from outside the WD Component itself. That said, you can pass the object reference (like the WD_COMP_CONTROLLER object reference or the View Object Reference) into methods of normal classes. Be careful if you are finding yourself calling a lot of your added methods from outside WD. This is probably a sign that these methods should be in the Assistance Class or some other Class functioning as a Model Object.
>2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.

What exactly do you want to do here? Do you just want to get the relaxation script? For what purpose? You should never need to inject the relaxation script into WDA.
>3. Is there any ways with which we can call portal event from ABAP class?
To what purpose. Do you just want to delegate the triggering of the event that is inside WD Component to be called from a class? If so you can pass the portal API object reference into a class from the WD Component. However this only works while running within WD.
How is this class used? Are you running in WD? Are you trying to generate some HTML code that runs in the portal independent of WD?

Hi all,
My requirement is to call portal from R/3 4.6C. As part of it I'm calling Portal URL along with user id & Password by using the FM CALL_BROWSER. The problem here is User ID & Password are visible everyone in the URL.
Is there any way that I can encrypt sothat it doesn't become a security issue?
I really appreaciate for your help.

Calling GUI Scripting from ABAP program

Is it possible to call GUI Scripting from ABAP and thus to use GUI Scripting as an alternative to CALL TRANSACTION?
Is the class CL_JAVA_SCRIPT suitable to access GUI Scripting engine? Accessing ABAP data object would work as well in this case as i think. What SAP Logon and WAS releases are required? Is the 6.20 release sufficient for this case?
I would appreciate if somebody could post an example.

Hi,
CL_JAVA_SCRIPT has nothing to do with SAPGUI Scripting.
Calling SAPGUI Scripting API from ABAP could be possible for programmes experienced with OLE automation calls from ABAP coding.
The hardest thing will be, to access the scripting engine handle as an entry point. Once you have a handle in your abap session, any api function can be invoked.
Best regards
Jens
BTW: SAP testtool eCATT does call SAPGUI-Scripting from ABAP.

Calling portal service from web service

Hello,
I'm trying to call portal service from web service. Is this possible? I'm getting an error.
For example, code:
IJCOClientService clientService = (IJCOClientService) PortalRuntime.getRuntimeResources().getService(IJCOClientService.KEY);
.. is generating exception:
java.lang.LinkageError: Class com/sapportals/portal/prt/runtime/IPortalRuntimeResources violates loader constraints
Do anybody knows what's wrong?
Best regards,

Hi Josef,
Is the IJCOClientService located on the producer side or on the consumer side?

Fire event from one class to another.

I have a Login JFrame class that allows users to enter username and password. I then have another JFrame class which will monitor when someone logs in. I am trying to get the username and password to appear on the monitor login frame text area when the user presses enter on the login frame.
I can get it ot work by passing the Monitor class into the Login classes constructor but I want to be able to open the classes separately.When I try to open separatley at present I get java.lang.NullPointerException
     at project.LoginGUI.actionPerformed(LoginGUI.java:70) which is referring to the following code:
if(listen.equals("OK")){
     GymMonitor.username.setText(username.getText());
Both classes are in the same package. What I want to know is how to fire an event from one class to another? when the class you are firing to is constructed separately.
I hope this question is not too verbose.
Thanks

Generally for something like this you would use a listener.
Your login window is its own entity--it has a user interface, and it gets some information which someone else could ask it for. It could even generate its own events, such as when the user presses "OK". You would first define an interface for anyone who wants to know when someone logs in:
public interface ILoginListener extends java.util.EventListener
public void login(LoginEvent event);
}You would then define the LoginEvent class to contain information like what the user entered for username and password. You could give your login dialog a couple of methods:
private Vector myListeners = new Vector();
public void addLoginListener(ILoginListener listener) {
    myListeners.add(listener);
public void removeLoginListener(ILoginListener listener) {
    myListeners.remove(listener);
protected void fireLogin(LoginEvent event) {
    for (Iterator it = myListeners.iterator(); it.hasNext(); ) {
      ILoginListener listener = (ILoginListener)it.next();
      listener.login(event);
}You'd have your login dialog call fireLogin every time the user logged in.
Then, you could implement ILoginListener in your monitor window:
public void login(LoginEvent event) {
    // now do something with the event you just got.
}All the code I put in here is really generic stuff. You'll write this kind of stuff hundreds of times probably during your career. I haven't tested it though.
Hope this helps. :)

Calling a method from another class... that requires variables?

I'm calling a method from another class to change the date (its a date object) in another class.
I keep getting the error 'setDate(int,int,int) in Date cannot be applied to ()'
My code is:
public int changeDate()
cycleDate.setDate();
}I'm guessing I need to pass 3 parameters (day, month, year), but I'm not sure how! I have tried, but then I get errors such as ')' expected?
Any ideas! :D

Error while calling java program from ABAP

Hi Experts,
We are trying for RFC inbound scenario.
We followed the below blog
/people/gregor.wolf3/blog/2004/08/26/setup-and-test-sap-java-connector-outbound-connection
We are working with SAP JCO 3.0.2
We are getting the error : 'STFC_CONNECTION' could not be found in the server repository.
After I run the Java server program if I execute the RFC destination directly from SM 59 it is showing successful messages.
If I stop the java program then this RFC is failing. Based on this we concluded that RFC to Java connection is working fine.
But as mentioned in blog if we call the RFC Destination from ABAP program it is giving the below error,
'STFC_CONNECTION' could not be found in the server repository.
If we test the RFC destination using RFC_TRUSTED_CHECK standard FM we are getting the below error.
'RFCPING' could not be found in the server repository.
We create the RFC destination of Type : TCP/IP as exactly mention in the blog.
Please help us in resolving this issue.
Thanks
Prince

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:

Yes, SAPHTTPA (runs on application server) and/or SAPHTTP (runs on front-end pc), one of which, is required for HTTP communication. So far, nothing too elaborate as far as SOAP goes, but the logic is simplistic. Here's some sample code:
DEST = 'SAPHTTPA'.
TRANSLATE HOST TO LOWER CASE.
MYURL = 'wssrvTest/Service.asmx/GetByOrderItem'.
CONCATENATE HOST MYURL INTO MYURL.
REQUEST_HEADERS-DATA =
 'Content-type: application/x-www-form-urlencoded'.
APPEND REQUEST_HEADERS.
CLEAR REQUEST_HEADERS.

 SPLIT RESPONSE_BODY-DATA AT '=' INTO FIELD_NAME FIELD_VALUE.

Parameters
IMPORTING Parameters
Parameter name
Use
COMMANDNAME
The name of the definition of the external command, as specified in the maintenance function (transaction SM69).
PARAMETERS
Arguments for the external command as specified by the definition in the R/3 System and by the calling program or user.
These arguments are checked for impermissible characters, such as the ; under UNIX. Problems are registered with the SECURITY_RISK exception.
EXPORTING Parameters
Parameter name
Use
STATUS
Returns the final status of the execution of the external command:
· Value O: The external command was started and ran to end successfully.
· Value E: An error occurred; the external command was not run successfully.
Tables Parameters
Parameter name
Use
EXEC_PROTOCOL
Contains the STDOUT and STDERR output of the external command and any output from the target host system.
Exceptions
Exception name
Meaning
X_ERROR
Reserved for future use.
NO_PERMISSION
The AUTHORITY-CHECK of the users authorization for the authorization object S_LOG_COM failed. The user is not authorized to carry out the command named with the specified arguments on the target system.
COMMAND_NOT_FOUND
Command name, as identified by COMMANDNAME and OPERATINGSYSTEM, has not been defined in the maintenance function (transaction SM69).
PARAMETERS_TOO_LONG
The combined argument string (ADDITIONAL_PARAMETERS and the DEFINED_PARAMETERS, as returned in ALL_PARAMETERS) exceeds the limit of 128 characters in length.
SECURITY_RISK
Either:
· The command contains impermissible characters. These are characters with potentially dangerous properties, such as ; under UNIX.
· The command definition specifies that an extra-check function module be run. This function module has rejected execution of the command.
WRONG_CHECK_CALL_
INTERFACE
The command definition specifies that an extra-check function module is to be run. Either this function module is missing, or the interface defined for this function module does not match that of the standard R/3 function module SXPG_DUMMY_COMMAND_CHECK. For more information, please see SXPG_DUMMY_COMMAND_CHECK: Interface for Extra-Check Function Modules.
TOO_MANY_PARAMETERS
The command definition specifies that user-specified arguments for the external command are not allowed. However, an additional string of command arguments was specified.
PARAMETER_EXPECTED
The command definition includes the placeholder character ?, which signifies that additional user-defined arguments are required. However, no additional arguments string was supplied.
PROGRAM_START_ERROR
An error occurred while starting the external command. The R/3 system field SY-MSGV1 contains additional information on the problem.
PROGRAM_TERMINATION_
ERROR
An error occurred while trying to obtain the return code of the external program. The R/3 system field SY-MSGV1 contains additional information on the problem.
ILLEGAL_COMMAND
The external command definition was modified "illegally". That is, the command was not modified by means of the maintenance function (transaction SM69).
The modified command is registered in the system log in its substituted form. The message is registered under the system log ID "LC".
OTHERS
Catch any new exceptions added to this function module.
Hope this will be useful.

Calling Java API from ABAP using JCo (Part 2)

Hello,
This is an additional question to thread Calling Java API from ABAP using JCo
Has anyone managed to get the input parameter value
input.getString("REQUTEXT")
that is being passed from ABAP?
If yes, what kind of setting you need to do? Because when I execute, it has no value.
Thus, the below ECHOTEXT parameter returns blank value:
output.setValue(input.getString("REQUTEXT"),"ECHOTEXT");
When I debug by printing the below line, the input XML is indeed without value:
System.out.println(input.toXML());
Anybody knows how to pass input variable from ABAP to JAVA using JCo?
rgs,
hiroshi

Hallo Hiroshi,
as far as I can see, you are doing it the right way. The problem might be that the ABAP program does not fill in this parameter because something went wrong in the SAP System.
Have you tried setting a breakpoint (an HTTP session - remote breakpoint) and tried checking step by step if the value is being processed and put into the REQUTEXT field?
Bye,
Sameer

Hi Nilesh,
From the error i think that the error is with the hostname.
Please enter the the Application Server IP/Hostname.
If you are loggin to SAP System "XX1" from SAP GUI. Then click the change Item tab and see Application server name/IP let say "XX2" for hostname or "xx.xx.xx.xx" for IP.
Replace srv[0] = new Server("gateway","sapgw00","JCOSERVER01",repository);
with srv[0] = new Server("XX2","sapgw00","JCOSERVER01",repository);
If App Server is IP then replace with
srv[0] = new Server("xx.xx.xx.xx","sapgw00","JCOSERVER01",repository);
Let me know if it is throwing any error.
Thanks,
