How to get current JNDI inside of bean?

Hello! I want to have two JNDIs for the one bean class. So there is no problem if I deploy the one bean twice in the same application with different JNDI. But at run time I want to know what JNDI's entry calls my bean. In this case how to get the current value of JNDI inside of instance of my bean?

Okay guys. I will explain the reason of this question,
may be then someone will be interested to this topic
and cold propose another idea how to arrange the
decision.
The question is about security. For example I have two
objects that realize two business warehouses. And I
want to use the one bean class for both objects of
course and also I want to have different permissions
with every of them. So my idea is to deploy two beans
contained the same class, into the one application jar
and assign different JNDIs to each bean.
That's is not a very smart idea. Why dont use EJB security features ?
Create two roles: warehouse1 and warehouse2. Pass authentication information from those EJB clients to container when you lookup a bean home interface. (That's the reason why you' r idea wouldnt work).
Now you can specify whis warehouse can call which EJB method. Also you can check it programmaticaly with isCallerInRole method.
best regards,

Then I could
set different permissions to every bean. Everything is
okay but also I don't want an explicit warehouse's ID
parameter for my bean class. Let it gets the ID of
warehouse as value of bean's JNDI. Only the problem I
don't know how to access to JNDI from the instance. I
supposed that I could get JNDI from current session
context, but there is no way to access the bound JNDI.

how to get current rowindex ?
Thanks
Sanjiv Sharma

Only way I can think of is to use the rowset controller from the InProc RAS SDK. Here is a snippet of a sample code on how to:
//Load the report
if (clientDoc != null) {
//create metadata structure
RowsetMetaData rowSetMetaData = new RowsetMetaData(); rowSetMetaData.setDataFields
(clientDoc.getDataDefinition().getResultFields());
       Fields fields = rowSetMetaData.getDataFields();
       String colName,colTypeName;
       int colType, len;
       Field field;
       HashMap colNames = new HashMap();
       HashMap colTypes = new HashMap();
       for (int i = 0; i < fields.size(); i++) {
               field = (Field) fields.get(i);
               colName =field.getDisplayName(FieldDisplayNameType.description, Locale
.ENGLISH);
               colNames.put("COL"+i,colName);
       colType = getColTypeFromVariant(field.getType().toVariantTypeString());
       len=field.getLength();
              //Placeholder
        //add column metadata to data structure or XML
        Object colValue;
        int rowCount=0;
        if (getMaxRows() != 0) {
               RowsetCursor rowsetCursor = clientDoc.getRowsetController(). createCursor
(null, rowSetMetaData);
              //Setting the batch size to make sure that you get back all the
              //rows by setting the batch size.
                    clientDoc.getRowsetController().setRowsetBatchSize (rowsetCursor
.getRowset().getTotalRecordCount());
           //Getting the Results back starting from the first row
           RowsetCursor resultCursor = clientDoc.getRowsetController(). createCursor(null,
rowSetMetaData);
           resultCursor.moveTo(0);
              while (!resultCursor.isEOF()) {
                  for (int i = 0; i < fields.size(); i++) {
                           colName=(String)colNames.get("COL"+i);
                           colTypeName=(String)colTypes.get("COL"+i);
colValue=record.getValue(i);
                            //Placeholder
//add row data to data structure or XML
resultCursor.moveNext();

How to get Current row of ViewObject in the DoDML methode

Hi all
I have two ViewObject EmplyesView and DeptView
How to get Current row of ViewObject DeptView in the DoDML methode of EmplyesView

OK, we can play this game on and on...
I'll ask for a use case (http://en.wikipedia.org/wiki/Use_case) and you don't give any info we don't already know. After an other 10 posts we probably know what you real problem is and can give you the advice which you could have gotten in the fist place.
So please take some time and describe the problem as if you would ask your mother for help. Tell us how the data model is build and how the VO are related. Is there any input from an user involved? Which information from the other view do you need? How do you get to the doDML method? Is there a button in the ui involved?

How to get current IUser (com.sapportals.portal.security.usermanagement)

Hi,
does anybody know how to get IUser for the current user?
I know how to get current IUser from com.sap.security.api package:
IWDClientUser wdcu = WDClientUser.getCurrentUser();
IUser sapUser = wdcu.getSAPUser();
but I need to have IUser from com.sapportals.portal.security.usermanagement package.
Regards,
Ladislav

Ladislav,
Try this:
Get the IUser uisng the API com.sap.security.api.IUser and store it in a variable, say <i>sapUser</i>.
Then,
// Convert the logged in user to old EP5 usermanagement API
com.sapportals.portal.security.usermanagement.IUser user = null;
try
com.sapportals.portal.security.usermanagement.IUser user = WPUMFactory.getUserFactory().getEP5User(sapUser);
catch (UserManagementException e)
e.printStackTrace();

How to get current assigned participant id?

Hi mates,
This might be a basic questions, but useful for me :)
How to get current assigned participant id from screenflow? Or How to pass it as an argument from interactive activity?
Below is what I tried.
Participant.id or Instance.participant.id - returns login user id
Thanks

Hi,
Please correct me if I understood wrong.
You want to know whether an instance is assigned or not and if assigned then you want to fetch the assigned participant id.
If this is your requirement then please find the code below and make the necessary changes into it.
Write the following code in screen flow automatic activity but before that you need to pass the instanceid as argument to the screen flow.
In the process as well as screen flow layer make an instance variable instanceid as Int.
Then make an argument variable instanceidArg as Int in both the screenflow and process layer and map accordingly so that it will take the instanceid from process layer to the screen flow layer.
Assign instanceid = id.number; in process layer automatic activity but before the global interactive activity where you have maped the screen flow.
Write the following code in screen flow automatic activity.
logMessage("============= instanceid ==============" + instanceid); //instanceid is the id of the instance that you have passed from process layer.
ProcessService ps;
InstanceFilter instF = InstanceFilter();
ps.connectTo(url : Fuego.Server.directoryURL, user : "<userid>", password : "<password>"); //In studio the userid and password will be same
logMessage("Connected");
instF.create(processService : ps);
instF.searchScope = SearchScope(participantScope : ParticipantScope.ALL, statusScope : StatusScope.ONLY_INPROCESS);
//<ProessId Name> is the id of the process where you want to know the assighed participant id
instF.addAttributeTo(variable : VarDefinition.processid, comparator : Comparison.CONTAINS, value : "/" + "<ProessId>");
instF.addAttributeTo(variable : VarDefinition.INSTANCE_NUMBER, comparator : Comparison.IS, value : Int(instanceid));
Fuego.Papi.Instance[] instances = getInstancesByFilter(ps, filter : instF);
foreach (instance in instances) {
logMessage("Assigned ?: " + instance.participantId.empty);
logMessage("instance.participantId: " + instance.participantId);
ps.disconnectFrom();

Urgent : How to get current user id

Hello,
fnd_global.user_id returns -1
fnd_profile.get('user_id',x_user_id) return null
can anyone help how to get current logged in user to apps.
Regards,
Dinesh.

Hi Dinesh,
You must also make sure you have initialised the app.
If you run this from sqlplus then it will return -1.
If however you run this from within a concurrent program then the user id will be returned.
Try using this from sqlplus fnd_global.apps_initialize
Eg.
begin
dbms_output.put_line(fnd_global.user_id);
fnd_global.apps_initialize(user_id => 3551,
resp_id => 1,
resp_appl_id => 1);
dbms_output.put_line(fnd_global.user_id);
end;

How to get current time and date??

How to get current time and date from my PC time and date to the java application??
i use java.util.* package but got error, that is:
- java.util.* and java.sql.* class are match
- abstract class cannot be instantiated
so what can i do, pls guide...thanks...

There is a method in the System class that will return the current system time. You could also instantiate a Date, Time, Timestamp, or Calendar object, all of which get created with the system time by default.
Don't import *. Import the specific classes you need.
Next time, post the actual text of the exceptions/compile errors. If you make people guess, most just won't bother.

How to get current task ID in BPM

Hi guys,
I have a requirement where I need to get the current active UWL task id in BPM context. I have seen the following code to create a direct execution url for a BPM task.
// begin session
      IUWLSession uwlSession;
      uwlSession = uwlService.beginSession(uwlContext, sessionIdleTimeout);
      uwlContext.setSession(uwlSession);
      IUWLItemManager itemManager = uwlService.getItemManager(uwlContext);
      QueryResult result = itemManager.getItems(uwlContext, null, null);
      ItemCollection items = result.getItems();
      Item item = null;
      for (int i = 0; i < items.size(); i++) {
        item = items.get(i);
        Map params = new HashMap();
        params.put("taskId", item.getExternalId());
        String executionURL = WDURLGenerator.getApplicationURL("sap.com/tc~bpem~wdui~taskinstance", "ATaskExecution", params);
This works fine, but this is looping through all the tasks assigned to a user. How do I get the current task ID. I want to use the code inside webdynpro application which is caled as a human activity in BPM. When this WebDynpro application is called I would like to know the current task ID.
As an FYI , UWL configuration passes the current task ID as a Dynamic parameter to "sap.com/tcbpemwdui~taskinstance"
application.
Please help if someone can identify how to get this value in my custom WD.
Thanks,
Yomesh.

Yes. there is no API to get the current task.
Try this:
WDProtocolAdapter.getProtocolAdapter().getRequestObject().getParameter("wi_id");
But i still say a bit confused with your requirement.
The task id gets created only upon creation of a task. And you want this current task id in the BPM Process context? How is it possible unless and until some action takes place and the data is passed from WDJ to BPM Context?
Please clear my doubt.

How to get current fiscal year.

Hi Experts,
I am working on Asset Management.I need to get current fiscal year.
I have to enter fiscal year on selections screen which i have to validate that it should not be greater than current fiscal year.
For above i have used following code snippet but i have hard coded variant as 'MK'.
To get variant i was using function '/IBS/RB_FI_GET_FISCAL_YEAR_VAR' but in my selection screen we have to enter multiple company codes. if i will keep this function inside loop then it may give multiple variants.
How to resolve this ?
DATA : l_year(4) type c,
       l_date TYPE sy-datum.
CALL FUNCTION '/IBS/RB_FI_GET_FISCAL_YEAR_VAR'

    OTHERS                       = 2.
l_date = sy-datum - 700.
l_date = l_date + 1.
