Overriding while instantiating

What is happening with the following construction which appears in example code MenuDemo.java.
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
Looks like an override tacked onto the end of a constructor. I have found no documentation
anywhere (several books, tutorial from Sun, etc.) that explains this form. Thanks in Advance

Ah, this is called BAD PROGRAMMING.
Anytime you call a method that requires some varible to be given to it...
in this case addWindow(WindowListener) you can do a few things.
1) You can give it a reference to another object such as WindowListener m
addWindowListener(m);
or
2) You can define an entire class inside the method - bad programming.
addWindowListener(new WindowAdapter() {public void ....});
basically, the code is creating a class-inside-a-class. The clas files create at compile time
would be the main class (example A.class) and then the inside class (A.1.class).
People do this sometimes just so they dont have to create another source file.
i.e. Lazy people.

Error while instantiating report Z_RD_ABSENCE_REPORT

Hi Guys,
we have just patched BWD, and while testing the broadcast setting i came across the following error.
Error while instantiating report Z_RD_ABSENCE_REPORT
Notification Number RSBOLAP 014
I am opening report designer and when i publish via Bex Broadcaster this message is shown. I have checked SDN and sap market place but most of the soultion seem to focus on WAD.
My feeling is that it is a JAVA error and is somethng basis might be able to fix.
Please can anyone let me know if they have come across this problem before, and help would be much appriciated.
Thanks
Forhad

Hello Forhad,
RSBOLAP 014 is a issue regarding communication between ABAP (backend ) VS BI Java side.
Read the note 937697 and follow his manual instructions.
This note will start the BI Diagnostics. There you will see a red mark with RSBOLAP issue. COrrect this red mark following the recommendation on "Action" field.
Good luck.

Getting status as ERROR while instantiating Business Object in work flow?

Hi,
Getting status as ERROR while instantiating Business Object in work flow.
How to rectify it.
Tahnks in Advance.
Moderator message: please have a look at the dedicated Workflow forum on SCN.
Edited by: Thomas Zloch on Jan 19, 2012

Hi,
Go to SWDD and create a new workflow. This workflow will have two steps. This is just for test purpose so we are not going to define any triggering event etc. First step will instantiate (creating a runtime object) a business object and second step will use that runtime object to execute one of its method. We know that to instantiate any BO we need the object key to be passed. Key uniquely identifies a runtime instance of Business Object (henceforth we will refer it as BO or business object interchangeably).
use Business Object SYSTEM and method GENERICINSTANTIATE to instantiate any Business Object in workflow

Error in @Override while chaning from JDK1.6 to JDk1.5

Hi,
I am getting following error while migrating from JDK1.6 to JDK1.5.
Multiple markers at this line
     - implements org.quartz.Job.execute
     - The method execute(JobExecutionContext) of type TransferFiles must override a superclass
     method
I have a class which implements Job interface having one method execute(JobExecutionContext context) . I am overriding this method inside one of my class by using @Override annotataion.
It is working absolutely fine in JDK1.6 but while migrating to JDK1.5 it is showing the above error.
Kindly help me in this regard.
Thanks,

Thank you very much for your kind help. I would like to tell you that by changing my enviroment to JDK1.5 from JDK1.6 it is asking for change the project facet. After changing the Project Facet from 6.0 to 5.0 I am getting error at @Override annotation line.

Clocking wizzard throws error while instantiating in IPI

Dear community,
I am using the ZedBoard without the PS side. My Goal is to create a 50MHz clock for my logic. So I use the 100MHz PL clock (the ZedBoard provides a 100MHz clock at Zynq pin Y9).
To get the 50MHz I am trying to use a MMCM which I would like to create with the clocking wizard. Therefore I do the following steps in Vivado 14.4:
creating new rtl project without any design files and choosing the zedboard
create block design
add ip --> clocking wizard
Then the following error occurs without instantiating the clock wizard (list of tcl commands):

How can I fix it?

Thanks first of all for your replies.
Allright, now I got some results. Or in different words: I can reproduce a strange behavior regarding the clocking wizard:
Leave the system language (win7) set to German and changing just the decimal separator (,) with (.) it does not work.
When I got the error message (see initial thread) than I can work around with closing Vivado and reopen it. If I try to instantiate the MMCM with the clocking wizard after reloading Vivado then it works (without error or warning messages). I even can gernerate a bitstream. But everytime I open a synthesized or implemented design I get the above mentioned errors. If I delete the clocking wizard at the IPI and try to add a "new" one then Vivado refuses it again (at least until I close Vivado and reopen it again). With this method I would say it works almost ;-)
set the system language (win7) globally to US English it works. At least I wasn´t able to reproduce this error.
Is this issue planned to be fixed in the next version of Vivado?
Regards!

Errors while instantiated a custom java object within jsp pages.

I'm currently trying to role out a war file created on JavaBeans IDE 3.5.1. I have custom created classes
that are instantiated by using:
used.TransactionsHolder p_transactions = (used.TransactionsHolder) session.getAttribute("s_transactions");
Where used is the package and TransactionsHolder
is the class I am trying to create an object from. When
I use this syntax I receive this error:
__transactionPage.java:90: cannot resolve symbol
symbol : class TransactionsHolder
location: package used
used.TransactionsHolder p_transactions = (used.TransactionsHolder) session.getAttribute("s_transactions"); //[ transactionPage.jsp; Line: 12]
;Any suggestions?

Can you please log a TAR with Oracle Support using Metalink to resolve this issue. They can help you collect all the log and trace files to determine the why this problem is occuring.

Problem while instantiating

I simply wrote this 2 lines of code:
import flash.display.DisplayObject;
var testIt:DisplayObject = new DisplayObject();
And I receive this weird error:
ArgumentError: Error #2012: DisplayObject$ class cannot be instantiated.
Any idea? Thanks in advance

DisplayObject is an abstract base class; therefore, you cannot call DisplayObject directly.

Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal ? in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse ?its? with ?it's?, ?loose? with ?lose?, or ?discrete? with ?discreet?. Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate boob you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate boob to save two entire keystrokes. Worse: writing like a l33t script kiddie hax0r is the absolute kiss of death and guarantees you will receive nothing but stony silence (or, at best, a heaping helping of scorn and sarcasm) in return.
If you are asking questions in a forum that does not use your native language, you will get a limited amount of slack for spelling and grammar errors ? but no extra slack at all for laziness (and yes, we can usually spot that difference). Also, unless you know what your respondent's languages are, write in English. Busy hackers tend to simply flush questions in languages they don't understand, and English is the working language of the Internet. By writing in English you minimize your chances that your question will be discarded unread.

ClassNotFoundException while instantiating ReportClientDocument

We have a very simple requirement to integrate CR within our web application. Our server side code is based on the Java platform (Struts/Spring/Hibernate). As a first iteration we want to simply use a pre-generated RPT file (itu2019s not even dependent on any DB right now) to render a report in a HTML page.
As of now we are just using an action class that creates a ReportClientDocument object, opens the RPT file, stores the object as a request attribute and forwards it to a JSP page for rendering. Much of the code is really a cut-n-paste job from the sample codes in the dev guide documentation. Below is the crux of the action class:
      final String REPORT_NAME = "/info/ADTestReport1.rpt";
      public ActionForward execute(ActionMapping pMapping,
                                                ActionForm pForm,
                                                HttpServletRequest pRequest,
                                                HttpServletResponse pResponse) throws ReportSDKException{
            ReportClientDocument rcd = new ReportClientDocument();
            //rcd.setReportAppServer(ReportClientDocument.inprocConnectionString);
            rcd.open(REPORT_NAME, 0);
            pRequest.setAttribute("ReportSource", rcd.getReportSource());
            return pMapping.findForward("success");
On successful execution, as is obvious from the above code, it forwards the request to a logical mapping called u201Csuccessu201D that points to the view component a JSP file. The JSP file is an exact copy of the sample code provided in dev guide except for the fact that instead of accessing the forwarded source object from session object we are accessing it from request object.
<%@ page contentType="text/html; charset=utf-8"
         import="com.crystaldecisions.report.web.viewer.CrystalImageCleaner,
                 com.crystaldecisions.report.web.viewer.CrystalReportViewer,
                 com.crystaldecisions.report.web.viewer.CrPrintMode"
%><%
Object reportSource;
CrystalReportViewer crystalReportViewer;
Retrieve ReportSource from HTTP Session and pass to CrystalReportViewer.
//reportSource = session.getAttribute("ReportSource");
reportSource = request.getAttribute("ReportSource");
crystalReportViewer = new CrystalReportViewer();
crystalReportViewer.setOwnPage(true);
crystalReportViewer.setPrintMode(CrPrintMode.ACTIVEX);
crystalReportViewer.setReportSource(reportSource);
crystalReportViewer.processHttpRequest(request, response, getServletContext(), null);
%><%!
Start image clieanup thread on JSP load.
Scan temp folder every 10 minutes to delete viewer-generated images 20 minutes or older.
public void jspInit() {
    CrystalImageCleaner.start(getServletContext(), 10 * (60 * 1000), 20 * (60 * 1000));
Stop the image cleanup thread on JSP unload.
public void jspDestroy() {
    CrystalImageCleaner.stop(getServletContext());
%>
The above is essentially the whole solution that we are using to get the RPT file and render a crystal report within a HTML page. However, the code throws the following exception at the point it tries to instantiate a ReportClientDocument object.
2010-12-06 11:19:10,325 ERROR org.apache.catalina.core.StandardWrapperValve.invoke - Servlet.service() for servlet action threw exception

      at com.crystaldecisions.sdk.occa.report.application.ReportClientDocument.n(SourceFile:1129)
This obviously points to a dependency on a class com.businessobjects.foundation.logging.LoggerManager class that doesnu2019t exist in the SDK. Has anyone faced this situation? Or can anyone help us in understanding the problem and what we need to do to rectify this issue?
Much thanks in advance.

The class you are looking for is contained in the jar file u201Clogging.jaru201D, which is part of the default jar files for crystal reports. It can be found in the folder C:\Program Files\Business Objects\common\4.0\java\lib

Getting error PLS-00307: too many declarations while instantiating object.

Hi,
I'm using oracle 10.2.0.4.0
I've created an object obj_bsk as follows:
create or replace type obj_bsk as object
(batch_set_key varchar2(64),
constructor function obj_bsk
return self as result,
constructor function obj_bsk(p_batch_set_key in varchar2)
return self as result,
member procedure display_batch_set_key
and object body as
create or replace type body obj_bsk as
constructor function obj_bsk
return self as result is
begin
self.batch_set_key := sys_guid();
return;
end;
constructor function obj_bsk (p_batch_set_key varchar2)
return self as result is
begin
self.batch_set_key := p_batch_set_key;
return;
end;
member procedure display_batch_set_key is
begin
dbms_output.put_line('batch_set_key is:' || self.batch_set_key);
end;
end;
Then I've created a package test_obj as follows:
specification:
create or replace package test_obj is
-- Author : TSHARMA
-- Created : 31/01/2012 10:32:37
-- Purpose : to test objects
my_bsk obj_bsk;
g_batch_set_key varchar2(64);
procedure show_obj_val;
end test_obj;
body:
create or replace package body test_obj is
procedure show_obj_val is
begin
my_bsk.display_batch_set_key();
end;
begin
-- Initialization
if (g_batch_set_key is not null) then
my_bsk := obj_bsk(g_batch_set_key);
else
my_bsk := obj_bsk();
end if;
end test_obj;
When I'm compiling the package I'm getting following error:
Compilation errors for PACKAGE BODY TSHARMA.TEST_OBJ
Error: PLS-00307: too many declarations of 'OBJ_BSK' match this call
Line: 12
Text: my_bsk := obj_bsk(g_batch_set_key);
Error: PL/SQL: Statement ignored
Line: 12
Text: my_bsk := obj_bsk(g_batch_set_key);
Can anyone please explain why oracle is viewing it as too many call for constructor when both constructors are different.
and how to resolve the issue.
Thanks
Tarun

I've solved the problem. Though it is strange.
The error occurred because I'm using p_batch_set_key as parameter constructor.
i.e. constructor function obj_bsk(p_batch_set_key in varchar2)
return self as result,
once I changed it to the same name as variable name in object it compiled fine.
i.e constructor function obj_bsk(batch_set_key in varchar2)
return self as result,
It is very strange. Can anyone plesae explain why the parameter name should be same as variable name in object.
Thanks
Tarun

which i think are just warning.
kindly help me out

Yes that could very well be the reason. You can try recompiling. If it does not fix, you can reload the whole datapump utility by using following metalink note:

Problem with model instantiation

I have an EJB model and while instantiating it in WDP I am getting an error at runtime:
The initial exception that caused the request to fail, was:
java.lang.NullPointerException
at -- Optimized, preallocated exception. No stack trace. Run VM with -XX:-OmitStackTraceInFastThrow to avoid this optimization. -- .()
I cant make any head and tail out of this. There is absolutely nothing in stackTrace other than the above message. I could instantiate my other EJB models and they are working fine. I dont know why this one particular model is giving some problems...
I tried reimporting/rebuilding/reload but in vain. My WS (which encapsulates EJB) is working fine.
Please help!!!

The compiler does not generate template instances that are already in libCstd, which is linked by default to programs. Instead of trying to force those instances into your shared library, you should build your library with a dependency on libCstd.
Remember that no system libraries are referenced automatically when you create a shared library -- you have to mention them explicitly. Normally you want to link against libCstd, libCrun, libm and libc. Refer to the C++ User's Guide that comes with the compiler, the "Building Libraries" chapter.

Problem while creating logical port using soamanager

Hi all,
I have created a client proxy for web service from a 3rd party system.
When i am creating a logical port for the same consumer proxy i get a error as follows:
RABAX_STATE -e: UNCAUGHT_EXCEPTION
and a dump saying
" The exception 'CX_SXMLP' was raised, but it was not caught anywhere along the call hierarchy.
Since exceptions represent error situations and this error was not adequately responded to, the running ABAP program
'CL_SXMLP_FRAGMENT=============CP' has to be terminated.
Please suggest what can be done or what can be the problem.
Thanks in advance.
Komal

Pls go to txn SM59 and check if the RFC destination for webservice is working in the test connection.
Then go to txn LPCONFIG and create the logical port using the RFC dest. Pls mention the path suffix appropriately.
Next in your code while instantiating the client proxy pass the logical port name in the constructor (if the LP is not maintained as default).
Pls reward points if the tips are helpful.
