C call-out and exception handling on HP_UX

Does anyone have experiencing calling out to C++ code which uses exception
handling on HP_UX? I'm having trouble getting this to work - details
below.
I'm trying to call out of Forte to some C++ code. The exposed functions
have been specified extern "C". This C++ code makes calls to the Lotus
Notes' C++ API. This API uses exception handling, as does our C++ code.
This all works great on Window NT. It's pretty cool, in fact.
It's not so cool on HP_UX. We're running 10.20, Forte 3.0.E. Apparently,
under HP_UX you have to compile and link using the +eh option in order to
use exception handling. So I did this. My test driver (which calls out to
my user object module) works fine.
So I fired up fcompile, passing in the +eh arguments, and the location of
one of Lotus Notes' shared libraries:
fcompile -cflags eh -lflags "eh /opt/lotus/notes/latest/hppa/libnotes.sl"
It works, giving me no errors.
Then I try to call the functions from inside Forte. It gives me the "Not
enough space loading library blah-blah-blah" error message. In my
experience, this message is misleading, and there's actually something else
going on. So I looked at the log file for the node manager. I saw these
messages:
/usr/lib/dld.sl: Unresolved symbol: __eh_Cqqsh_DynScope (data) from
/tools/forte/EdgeNotes/userapp/conplus_/cl0/lnapifor.sl
/usr/lib/dld.sl: Unresolved symbol: __eh_dt_count (data) from
/tools/forte/EdgeNotes/userapp/conplus_/cl0/lnapifor.sl
/usr/lib/dld.sl: Unresolved symbol: __eh_reset_dt_count (data) from
/tools/forte/EdgeNotes/userapp/conplus_/cl0/lnapifor.sl
/usr/lib/dld.sl: Unresolved symbol: __eh_Cqqlo_Object (data) from
/tools/forte/EdgeNotes/userapp/conplus_/cl0/lnapifor.sl
/usr/lib/dld.sl: Unresolved symbol: dealloc_object__18__eh_thrown_objectFi
(code) from /tools/forte/EdgeNotes/userapp/conplus_/cl0/lnapifor.sl
I don't know what this all means. In an attempt to replicate the situation
as closely as possible, I tried linking in the shared library (created by
Forte) to my driver program, and ran my driver program. It worked,
although it gave me the following warnings:
__link_incompatibility: Warning: Shared library
/tools/forte/EdgeNotes/install/lib/libqqfo.sl was not compiled with +eh.
__link_incompatibility: Warning: Shared library
/tools/forte/EdgeNotes/install/lib/libqqrpgs.sl was not compiled with +eh.
__link_incompatibility: Warning: Shared library
/tools/forte/EdgeNotes/install/lib/libqqsm.sl was not compiled with +eh.
__link_incompatibility: Warning: Shared library
/tools/forte/EdgeNotes/install/lib/libqqdo.sl was not compiled with +eh.
__link_incompatibility: Warning: Shared library
/tools/forte/EdgeNotes/install/lib/libqqcm.sl was not compiled with +eh.
__link_incompatibility: Warning: Shared library
/tools/forte/EdgeNotes/install/lib/libqqknpthrd.sl was not compiled with
+eh.
Hmmm .... After further investigation, I found that the
"__eh_Cqqsh_DynScope", "__eh_dt_count", and
"dealloc_object__18__eh_thrown_objectFi" symbols are referenced from my
user object module, and not from any of Forte's libraries (via the nm
command).
My guess is that there's an incompatibility between the forte run-time, and
my code, and I'm further guessing that this incompatibility is related to
the fact that my code is using exception handing.
I'm in contact with Forte Tech Support, but I wanted to see if anyone on
this list has ever run across this.
Thanks,
Dan

I did not know that the 9.2 Oracle ODBC driver was not certified for Oracle 7
In fact, when I read the help in the Oracle Net Manager that I installed from the same package (OraWin9204.exe), I can see that there is a normal conncection possible between the packed software and Oracle 7. Downward compatibility is something we should expect from astate-of-the-art RDBMS like Oracle.
I do not have the Oracle 7 ODBC driver installed, I was since two years using the Oracle 8 ODBC driver wich worked fine with both Oracle 7 and 8 but due to upgrading of one of our production databases to Oracle 9 I had to install the Oracle 9 software.
As I stated in my original mail, when testing the Oracle 9 driver in the Data source (ODBC) off my WinXP, it gives a perfect result while connectiing to the System DSN I configured for the Oracle 7 database.
But when opening Access2003 and linking tables, the ODBC call always fails

    What i actually want to do is SnailTravel, but i facing some problems, which is the
    - Constructor,setter, getter, and
    - Exception Handling.
    So i create another simple contructor files which name Employee and TestEmployeeClass, to try find out the problem but i failed, it come out error msg "cannot find symbol".
    What i want to say that is if i cut below code (SnailTravel) to its own file(SnailData), SnailTravel come out error msg "cannot find symbol".So i force to put them in a same file(SnailTravel) to run properly.
    I need help to separate them. (I think i miss some syntax but i dont know what)
    And can somebody help me about Exception handling too pls.
    class SnailData{
       private double distance;
       private double speed;
       private double time;

  • Why my new 4s call out and my friends can not hear me?

    why my new 4s call out and my friends can not hear me?

    Sounds like your microphone might be busted.  Test it by doing a voice memo. If this is the case you should take it to your service provider/carrier/nearest apple store to have it looked at.
    Alternatively, try using headphones or a bluetooth headset. These are all steps to make sure it's not the mic that's damaged.

  • What is the idea behind Render Response and Exception Handling in TF?

    Dear All,
    While searching for answer for my question, I find it hard to decipher this line.
    task flow exception handling doesn't handle any exception that is in Render Response phase
    I found this several times in many post like this.
    Re: ADF Exception handling (including RENDER RESPNSE PHASE)
    and this
    Re: Exception Handling in TaskFlow
    What's the idea behind exception handling in task flow that is related to JSF/ADF life cycle?
    I can't find a resource on why I should know what phase an exception has been thrown?
    Sorry if my question might be vague/ignorant to others, but I just would like to know the idea from experts around here. :)
    Thanks.
    JDEV 11G PS4

    Hi,
    Render Response is the last lifecycle phase processed during JSF request. The ADF controller has no chance of handling exceptions that occur during this time (example, exception thrown in managed bean) and therefore in its default exception handling implementation ignores this lifecycle phase. As an application developer you don't need to know when an exception is raised. However, if you find that an exception occurs during Render Response and it is not handled by the ADFc declarative exception handler, then you know. You can try and override the framework exception handler as explained here:
    https://blogs.oracle.com/jdevotnharvest/entry/extending_the_adf_controller_exception_handler
    However, better practice is to use try/catch blocks surrounding e.g. calls in a managed bean that could cause exceptions

  • Skype Number, Calling out and in

    Hi Skype Community
    I wan't a Skype Number for my webshop and need to know. If I have a Skype number. Can I call to others? and can my customer call me?

    Hi, MaxXGaming, and welcome to the Community,
    Please remember this: a Skype Number provides a fixed or land line number for people to use to call you, and you answer the call on Skype.  In other words, incoming calls only.
    You will need credit or a subscription to cover the cost of calls you make from Skype to fixed or land lines and mobile numbers.
    Maybe the product names should not have been changed?!
    Skype Number = Skype In
    Calls to fixed lines and mobile numbers = Skype Out - credit or subscription needed.

  • Residential phone: we can call out, and we can also receive calls, but the phones don't ring...

    this just started today, sometime after 9am. working fine before then, and we didn't touch anything re: the system today.
    behavior:
    - we can call out fine
    - people calling in say it just rings & rings
    - we have no idea that someone is calling unless we happen to be looking at the CID of a plugged in phone
    - we can pick up the phone and have a conversation if we happen to catch it at just the right time
    - same behavior at the NIC or whatever it's called (the box in the garage).
    tried: 
    - i've unplugged our main wireless phone and tried it w/a wired phone, no change 
    - i've unplugged our verizon broadband modem, no change
    we have a tivo that uses the phone line; i'm about to give that a shot. 
    this is really bizarre...
    thanks for any ideas,
    scott.

    Sounds very strange! I hope your house isn't haunted. =P

    Hey Chris,
    I got the point for exception handling in weblogic 9.2. We ae using 9.2. It comes up with the concept of shared page flows which means all my unhandled exceptions are thrown to the shared page flow controller. There based on the type of exception, i can forward the request to appropraite page.
    Thanks anywyas,

  • Can't call out and no dial tone

    I was told that there is a problem with a cable in the Brooklyn, NY area, but I can not find any other person in my neighborhood who has the problem.
    The phone was working fine Sunday night and then Monday morning no dial tone and I am dead in the water.
    I use my phone for my business and contacts, now nothing works properly.
    I called Verizon and was told that they would have it resolved by the 4th of July (2012) and that this problem is affecting about 1200 customers in my area.
    I called a couple of hours later and was then told that the service would not be repaired until July 10th 2012, which is totally unacceptable.
    Is there anyone in the Brooklyn area having the same problem. Why can't Verizon just bypass the bad lines, just to keep the service up and running.
    Where can you go to complain about this.  It seems my only option now is to move my number to another carrier, which I don't want to do.
    Please let me know, if anyone has any ideas.
    Thanks

    Sorry for the troubles you have had with the service. Did you still need assistance? Reply back if so that way we can take a look.

  • Embedded Java in BPEL and exception handling

    Hello everybody,
    i want to use some embedded java code in my BPEL process (bpelx:exec). This code would sometimes throw exceptions. How can i deal with these exceptions to control my BPEL process? I would like, in a sense, to do some catching of java exceptions but at the BPEL level... for example, my java code would throw an exception, that my BPEL process would "catch" and react the way i want. Is it possible to do that?
    Thanks for your help!
    Nicolas

    you need to throw a com.oracle.bpel.client.BPELFault ..
    from the code
    * This class represents a standard fault that may be thrown by the server
    * during run-time. A BPEL fault has defined, minimally, a QName that
    * corresponds to the fault name (there are several standard faults that
    * are supported, please refer to Appendix A - Standard Faults in the BPEL
    * 1.1 specification for a complete list).
    * <p>
    * This class can only be used from within a <code>bpelx:exec</code> activity;
    * the <code>throw</code> activity can be used from BPEL code.
    * <p>
    * Additional information (such as a fault variable) can be passed through
    * as a part. Currently, internal system errors populate error codes and
    * summary messages via parts.

  • Calling EJBs from Global Exception Handler

    Hi, I'm using Weblogic Workshop 8.1.4.
    I have a JPF which calls a EJB to set a lock flag (to prevent the JPF being executed twice at the same time.)
    I want to reset the lock flag in the global exception handler, however, if I call an EJB (Entity or Session) in a perform node in the exception handler, I get a NullPointerException.
    Is this because it's being called in the exception handler? Is there any way to work around this (without building a POJO which does all the persistance logic and SQL calling manually?)
    Thanks.

    You can redirect stdout to wherever you want by using
    System.setOut(PrintStream out). Also, you can give
    printStackTrace a PrintStream.
    hth,
    mI think to solve this problem you should call System.setErr(PrintStream err);

  • Will Service call out return an exception with an object embedded in it

    Hi,
    I have a service callout in a request pipeline.Service will throw an exception with a custom object embedded inside the exception.When i see the response $fault in the service error handler, i dont see the object.Is this something which can be done or not?if yes then guide me through it.

    Hi,
    If you invoke the service call out, and it returns a soap fault (make sure that it returns http 500), so you should be able to access the custom fault element inside $fault/con:details/con1:ReceivedFaultDetail/con1:detail
    Are you sure that your webservice is returning the fault properly?
    Are you not raising a new error after getting the response in the error handler, right?
