How to catch SAP application errors in BPM.

Hi,
I have a IDOC to Soap Sync Scenario where I send the message to a Webservice. I have used a BPM since we need to catch the resposne of this message and map it to a RFC. For ex if I get a success resposne I need to map success if not than I need to catch the error and map it to the RFC. Now here in some cases like if the target system (webservice) is down than XI raises a sap application error:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- 
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
<SAP:Category>XIAdapterFramework</SAP:Category>
<SAP:Code area="MESSAGE">GENERAL</SAP:Code>
<SAP:P1 />
<SAP:P2 />
<SAP:P3 />
<SAP:P4 />
<SAP:AdditionalText>com.sap.aii.af.ra.ms.api.DeliveryException: Connection refused (errno:239)</SAP:AdditionalText>
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack />
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
Normally XI stops the process in these cases and does not proceed to the next step but I need to catch this message and map the content in the AdditionalText to the target RFC. Can anyone let me know how to catch this SAP Application Error in BPM and map it to the RFC.
Thanks,
Bhargav

Hi Gaurav,
As I have mentioned I need to catch the application error in the BPM. If you see the discussion that is mentioned after the blog you have mentioned it is stated that the fault messages or the application error cannot be caught in BPM.
In the blog that you stated we can catch the fault message and map it to a message structure but only to that extent after that it would stop the BPM process at that step but would not proceed further as shown in the screenshot given in the blog it would fail as "application error restart not possible".
I need to proceed further and capture this error to an RFC Structure and call a proxy.
Here after the error it does not proceed to the next step.
Thanks,
Bhargav

How to catch and display a link content in another portlet page?

Can you tell me how to display a URL content into next page after an user click s on this link? I am developing a JSR 168 portlet under a Portal. I have 3 pages so far in my portlet. view.jsp, view2.jsp and IpByHourPage.jsp. view2.jsp displays a lis of IP address. When an user clicks on an IP in view2.jsp, it goes to IpByHourPage.jsp. How to catch the IP address such as 123.23.89.21 that an user just click displayed in IpByHourPage.jsp. I don't know why I got null value returned.
Also, I don't know how to do a "go back to previous page". I want to go back to view2.jsp from IpbyHourPage.jsp
Here is my code
in view2.jsp
<portlet:renderURL var="aURL">
<portlet:param name="goto" value="IpByHourPage"/>
</portlet:renderURL>
<a href="<%=aURL.toString() %> "><%=MyIP%></a>
in IpByHourPage.jsp
<%
String MyIPHour = request.getParameter("goto");
%>
<h1>IP Report by Hour ( <%=MyIPHour%> )</h1>
<portlet:renderURL var="Ret_IPByHour">
<portlet:param name="Ret_IPHourPage" value="Ret_IPByHourPage"/>
</portlet:renderURL>
<center> <a href="<%=Ret_IPByHour.toString() %> "><b>Choose Another IP</b></a></center>
in my .java file
protected void doView(RenderRequest request, RenderResponse response)
throws PortletException, IOException, UnavailableException {
response.setContentType("text/html");
String MyBegDate = request.getParameter("BegDate");
String MyEndDate = request.getParameter("EndDate");
String MyNetworks = request.getParameter("networks");
String MyYourName = request.getParameter("yourname");
PortletURL renderURL = response.createRenderURL();
renderURL.setPortletMode(PortletMode.VIEW);
request.setAttribute("renderURL", renderURL.toString() )
String GotoRenderAction = request.getParameter("goto");
String MyIPHourAction = request.getParameter("Ret_IPHourPage");
if ( (MyIPHourAction!=null) && MyIPHourAction.equals("Ret_IPByHourPage") )
PortletRequestDispatcher kk = getPortletContext().getRequestDispatcher("/view2.jsp");
kk.include(request, response);
if (MyIPHourAction != null && MyIPHourAction.equals("Ret_IPByHourPage"))
PortletRequestDispatcher mm = getPortletContext().getRequestDispatcher("/view2.jsp");
mm.include(request, response);
if (GotoRenderAction != null && GotoRenderAction.equals("IpByHourPage"))
request.setAttribute("BegDate", "MyBegDate");
request.setAttribute("EndDate", "MyEndDate");
System.out.println("BegDate" + MyBegDate);
System.out.println("Endate" + MyEndDate);
PortletRequestDispatcher mm = getPortletContext().getRequestDispatcher("/IpByHourPage.jsp");
mm.include(request, response);
if(MyEndDate!= null )
PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/view2.jsp");
prd.include(request, response);
else if (MyEndDate==null && GotoRenderAction == null)
PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/view.jsp");
prd.include(request, response);
The problem for above code is the clicked single IP can not be displayed in IpByHourPage.jsp. and I cannot go back to view2.jsp from IpByHourPage.jsp. when I click "Choose Another IP"
I find out that the MyBegDate and MyEndDate values are all null when I click Choose Another IP link. I got the following error message
Caused by: javax.servlet.ServletException: Unparseable date: "null null"
     at org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:858)

     at org.apache.jsp.view2_jsp._jspService(view2_jsp.java:651)
     at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97)
How to fix above problems. Thanks

I think the problems are related to portletsession. But I don't know how to use it. How to put portletsession into doview method or my jsp pages. Can anyone tell me in my code? Thanks a lot.

How to catch SQLException from a session bean

Hello
I have a stateless session bean which has a method to persist an entity (User) in the database. In User there is a foreign key (addressId) from another entity (Address). While i was persisting User, i entered a value of addressId which was not present in the Address table. Since there was a foreign key constraint on this field in User i got the following exception:
8:49:49,421 ERROR [JDBCExceptionReporter] ORA-02291:
integrity constraint (FK_USER_ADD) violated - parent key not
found 18:49:49,421 ERROR [AbstractFlushingEventListener]
Could not synchronize database state with session
org.hibernate.exception.ConstraintViolationException: could
not insert: [com.User] at org.hibernate.exception.SQLStateConverter.convert(SQLState
Converter.java:71)So i placed the persist code inside a try block and was catching all the exceptions thrown by persist() method. But these exception are not caught. Instead the exception is sent to the Client end and printed on the client console.
Any clue on how to catch the ConstraintViolationException in the session bean?
Thanks

The problem is that the qry is not executed until you leave your method, so, the exception is catched by the Container. You should issue a entityManager.flush(); rigth "before" leaving the method and you are going to catch all the exceptions given
Cheers

How to catch exception throw bc4j

Dear Forum
I am user of JDeveloper Swing application.
while exception throw from bc4j some particular
type error such as (oracle.jbo.DMLException) JBO-26041
message display.
i want to catch error no 26041 inorder to display own
messageBox.
There is two methods
1-:
i used messageBundle class i overite message string but unable to change dialogBox,i want to use own dialog.
2-:
And i fund ,DML exception message return from JUErrorHandlerDlg class.So using this subclass how
to catch and throw own message.
Plase send me some code to write sub class of JUErrorHandlerDlg.

You want this method System to throw an exception if the String[] is empty?
public void system( ObjectOutputStream output, String cmd [] ) {
if (cmd.length == 0)
throw new IllegalArgumentException("Hey! This is an empty array!");
//...rest of your method
}You can choose for yourself which exception type is most appropriate. You can in theory always use the base Exception but is not very specific nor recommended. In this case, I think an existing unchecked exception such as IllegalArgumentException would be the most appropriate.

hi,
can any one tell me how to catch the value in sum in control break satament.

sum.
endat.
I need to print the value in sum only.
I tried to declare a varaible of type i and assigned sum to this variable.
it is giving syntax error that sum is not identified.
How should i do this.

Hi Siva,
In control break statement when we use SUM. it added all the amount fields and stores its in the work area of that field.
look below code.
DATA : BEGIN OF itab OCCURS 0,
           name(10),
           num TYPE i,
       END OF itab.
DATA : num TYPE i .
itab-name = 'salman'.
itab-num = 100.
APPEND itab.
itab-name = 'salman'.
itab-num = 200.
APPEND itab.
itab-name = 'akshay'.
itab-num = 500.
APPEND itab.
LOOP AT itab.
AT END OF name.
    SUM.
    WRITE : / itab-num.
ENDAT.
ENDLOOP.
here the SUM value is stored in Workarea,
the output will be 300 & 500.

fault message type

Hi Spring,
If u give an exception step along with your Transformation Step, whenever some error occurs in your message mapping, this exception block wil be triggered.
You can configure your exception block to do all exception processing that you want. This exception handling is like any other java Exceptio n Handler. You can do anything that you want in your exception handler block on the basis of your requirements.
<i>If an exception is triggered at runtime, the system first searches for the relevant exception handler in surrounding blocks. If it does not find the correct exception handler, it continues the search in the next block in the block hierarchy.
When the system finds the correct system handler, it stops all active steps in the block in which the exception handler is defined and then continues processing in the exception handler branch. Once the exception handler has finished processing, the process is continued after the block.
If the system fails to find an exception handler, it terminates the integration process with an error.</i>

Bhavesh

OC4J 10.1.3: EJB3 - How to catch SQLExceptions in a SessionBean

Hi,
originally I posted this a few minutes ago in the toplink forum, but I'm
unsure if this better suits here. So exceptionally, I post it here as well with a
reference to:
EJB3 - How to catch SQLExceptions from within a stateful session bean
I would like to catch any exception while persisisting the data right in my stateful
session bean and don't have to wait until the client receives an SQLException
wrapped in a bunch of other exceptions.
Here some code fragments to illustrate my problem:
// in Client:
InitialContext ctx = new InitialContext();
statefulWork = (StatefulWork) ctx.lookup("StatefulWork");
try {
statefulWork.doIt();
} catch (Throwable t) {
// don't want to implement db-failover here, even though this works
// in SSB
@Resource
private EntityManager em;
public void doIt() {
        try {
            // create some entites here, do some loops, long running transaction
            em.persist(oneOfMyEntityObjects);
            // set some state in the SSB here
        } catch (Throwable t) {
            // I want to catch all exceptions the persistence provider (toplink) gets
            // but I don't get any here :-(
            // this should be to implement proper retry after reconnect (RAC with TAF)
}In my testcase I issue a shutdown abort while insert statements are executed.
The client receives an EJBException, but within the SSB nothing...
How to change this behavior?
Here is what one can find in the OC4J log:
[TopLink Warnung]: 2006.03.27 03:25:32.220--UnitOfWork(13386)--Thread(Thread[RMICallHandler-0,5,RequestThreadGroup])--Exception [TOPLINK-4002] (Oracle TopLink - 10g Release 3 (10.1.3.0.0) (Build 060118)): oracle.toplink.exceptions.DatabaseException
Interne Exception: java.sql.SQLException: ORA-25402: transaction must roll back
Fehlercode:25402
Call:INSERT INTO T_RUN_DETAILS (ID, INS_TIME, COUNTER, RUN_ID) VALUES (105781, '2006.03.27 03:23:55', 450, 801)After that the transaction is properly rolled back (automatically) and the client
could implement the failover code, but I could not find a possibility to control this
at server side. Even with BMT I could not manage to catch this exception. I
wouldn't have a problem if I had to call ctx.setRollbackOnly() myself.
Hope someone can help. I'm getting a little desperate here.
Thanks,
Eric

Thanks to the help of James Sutherland I managed to get this working.
I had to add a call to em.flush() and use BMT for the SSB. For details please follow my link to the toplink-forum!
James thinks OC4J can handle automatic transaction retries but wasn't sure about how to configure this in OC4J. Anyone can help?

Eric

How to catch java.io.FileNotFoundException when user enters a.jsp which is not a vali

How to catch java.io.FileNotFoundException when a user enters a bogus jsp page. For example. I have a page called login.jsp. If a user enters log.jsp, the entire path is show and i get java.io.FileNotFoundException. This should not happen. This only happened since I upgraded to 9iAS. I tried send_error=true in zone.properties like i did when i was just using oracle http that came with database and it doesnt work. How are all you guys catching this?? I cant find any documentation. They say send_error=true will work, but IT DOESNT.
Thanks for your time

How to catch due Items for open Items for vendors

hello everybody,
How to catch due open Items amounts for vendors
for 0-30 30-60 60-90
regards
Mave

Hi
Mave
You have to get the open items from BSIK and then calculate the due date (there's only the baseline date, ZFBDT, in BSIK), you can use fm NET_DUE_DATE_GET to do it:
LOOP AT I_BSIK.
CALL FUNCTION NET_DUE_DATE_GET.
   EXPORTING
     I_ZFBDT = I_BSID-ZFBDT
     I_ZBD1T = I_BSID-ZBD1T
     I_ZBD2T = I_BSID-ZBD2T
     I_ZBD3T = I_BSID-ZBD3T
     I_SHKZG = I_BSID-SHKZG
     I_REBZG = I_BSID-REBZG
     I_KOART = 'K'
   IMPORTING
     E_FAEDT = DUE_DATE
Now you can calcultate the range:
   DELTA_DAY = SY-DATUM - DUE_DATE.
   IF DELTA_DAY < 30.
ENDLOOP.

I need to execute a procedure that select remote objects but the remote db is a RAC DB and I only have access to one of the nodes, the remote RAC have load balancing enabled and the remote DBA can’t create a DB Service for my connection, so, I have to re-run the execution of my procedure until it connects successful to the remote DB through a db link, but I can’t catch the error ORA-12541: TNS:no listener.
Someone knows how to catch the error??
set serveroutput on
declare
function F_DATE return sysdate
is
ld_return date;
begin
begin
select sysdate into ld_return from dual@dbl_bnvalores;
exception
when others then
ld_return := f_date;
end;
return ld_return;
end F_DATE;
begin
dbms_output.put_line('Remote sysdate: '||f_date);
end;
Error at line 2
ORA-06550: line 2, column 26:
PLS-00562: a function must return a type.
ORA-06550: line 7, column 42:
PL/SQL: ORA-04052: error occurred when looking up remote object BNSAFI.DUAL@DBL_BNVALORES
ORA-00604: error occurred at recursive SQL level 1
ORA-12541: TNS:no listener
ORA-06550: line 7, column 7:
PL/SQL: SQL Statement ignored

I could confirm that you would never branch to the exception in case of no listener!
So another possibility that comes to mind is to enclose the remote select in an execute immediate and only execute it if you could establish a connection via UTL_TCP:
Something along those lines:
michaels> DECLARE
   conn               UTL_TCP.connection;
   l_date             DATE;
   no_listner_excep   EXCEPTION;
   PRAGMA EXCEPTION_INIT (no_listner_excep, -29260);
BEGIN
   conn := UTL_TCP.open_connection ('fleet', 1569);
   EXECUTE IMMEDIATE 'select sysdate from dual@fleet_new'
                INTO l_date;
   UTL_TCP.close_connection (conn);
   DBMS_OUTPUT.put_line (l_date);
EXCEPTION
   WHEN no_listner_excep
   THEN
      DBMS_OUTPUT.put_line (SQLERRM (SQLCODE));
END;
ORA-29260: network error: TNS:no listener
PL/SQL procedure successfully completed.

How to catch Delta Initialization and Delta Update in a Function Module

Hi Experts:
I'm developing a FM to extract data from R3. I wonder if anybody knows how to catch when i'm making a delta initialization and a delta update in my FM, because i have different parameters and routines from each one.
Thanks in advanced.
Points for helpfull answers.

Hi,
Keep one dummy date field in the structure. Make this dummy date field as delta enabled field. When you do Init load this date field value will be blank and next time when you do load it will have the last upload (in this case init load) date. You have to write a code before open cursor as below:
      LOOP AT s_s_if-t_select INTO l_s_select.
                              WHERE fieldnm = '(dummy date field name)'.
         l_date = l_s_select-low.
      ENDLOOP.
l_date will have the last upload date. This you can use to select the delta records from the table or for the further processing.
If you want to check the value during Init or delta load, go to RSA3 and debug it(Don't use F - Full load. Use I or D in the update field).
Hope this helps.
PB
