Abstract Method Error in retrieving Blob

Hi!
while (rs.next())
Blob blob=rs.getBlob(1);
throws Abstract Method Error
why?
Thanxs in advance

You'll probably find that the JDBC driver that you are using doesn't support blobs. Check the documentation that comes with your driver, it should tell you what parts of the JDBC specification it supports.

Abstract Method Error and XML Parsing

I am using wl6sp1. I am parsing an XML file from within the
servlet using jaxp1.1 and crimson.
Following is code:
1- SAXParserFactory spf = SAXParserFactory.newInstance();
2- sp = spf.newSAXParser();
3- xr = sp.getXMLReader();
4- xr.setContentHandler(new ParseXML());
5- xr.parse( new InputSource("Example3.xml"));
This program works fine when execute from command line but in servlet on line
3 it says:
"Abstract Method Error"
I have created XML Registry to use Crimson as XML parser rather than default.
I think somehow wl is still using jaxp1.0 which is built in
support in wlsp1.
Whats wrong with the code...or what configuration i am missing???

I'm assuming you have already put crimson.jar first in the classpath for the java
command you use to start WebLogic. If so, have you tried putting the servlet in
a .war file with the crimson.jar in its' WEB-INF/lib directory?

Is not abstract and does not override abstract method ERROR

Hello. I'm new at all this, and am attempting to recreate a sample code out of my book (Teach Yourself XML in 24 Hours), and I keep getting an error. I appriciate any help.
This is the Error that I get:
DocumentPrinter is not abstract and does not override abstract method skippedEntity(java.lang.String) in org.xml.sax.ContentHandler

 if (args.length == 0)
 System.out.println("No XML document path specified.");
 System.exit(1);

 DocumentPrinter dp = new DocumentPrinter();

public void fatalError(SAXParseException exception)
System.out.println("Fatal parsing error on line " + exception.getLineNumber());
public void warning(SAXParseException exception)
System.out.println("Warning on line " + exception.getLineNumber());

Check to make sure that the arguments are consistent with your ContentHandler class. Probably the wrong type.
I think you forgot to include the skippedEntity method, it seems to be missing. Even if an implemented class has a method that you are not using, you still have to include the method in your code even if it doesn't do anything.

Abstract Method Error

Hi All ....
i m having problem when i call the method Connection.createStatemen(int,int). it gives the error java.lang.AbstractMethodError. i m calling from inside servlet. same error occures when i call method getRow() of ResultSet. here is all the code.
please tell me i m wrong Or some thing else is there.
thanks in advance
Connection conn=pool.getConnection();
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
//Statement stmt=conn.createStatement();
sql="Select * from TblClients";
ResultSet rs=stmt.executeQuery(sql);
out.println("<HTML>");
out.println("<HEAD>");

Using Weblogic JDBC driver 5.1.0sp8 with MSSQL, throwing "abstract method" error when trying to use scrollable resultsets

I am using the weblogic driver with Allaire JRun.
Using these lines, I am trying to make my resultsets scrollable and updatable.
dbConnection.createStatement( ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE
ResultSet rs = queryStatement.executeQuery(query);
When I run the code, I get this error ..

Everything works fine when I do not try and specify attributes to the statement
object. (i.e. dbConnection.createStatement();)
Anybody know what is going on?
thanks,

Hi. I don't see our code anywhere in the stacktrace, but I'll assume
it's there somewhere. The basic fact is that our MS SQLServer driver
implements practically zero of the JDBC 2.0 methods. There is a way
to connect to this driver that has the methods defined, but then all
the difference will be that you'll get an exception saying 'this jdbc 2.0
method not implemented'.

Getting error while creating abstract method

hi folks,
i facing issue for ABSTRACT Class.
I am trying to create abstarct method, (refered example from saptechnical site),
I created one attribute i-num, created one method AREA, in implementation area , i made it as Abstract, then i did syntax check, then it is giving below error.
*Class ZTEST_CLASS01_AB,Method AREA
The abstract method "AREA" can only be implemented after its
redefinition (METHODS AREA REDEFINITION).*
i tried all the ways..
created subclass for this, i writted some code in AREA of Sub-class, there it is giving dump, because first one is not activated properly..
could you please somebody help me on this.
Sri

Hello Arshad,
Create a class(ZABSTRACT) and make its type as Abstract( Which means atleast one of its methods is abstract)
We can have abstract classes with all it's methods as non-abstract or concrete. A small example is given below:
CLASS gcl_abstract DEFINITION ABSTRACT.
PUBLIC SECTION.
    METHODS concrete. "Concrete
ENDCLASS.                    "gcl_abstract DEFINITION
*       CLASS gcl_abstract IMPLEMENTATION
CLASS gcl_abstract IMPLEMENTATION.
METHOD concrete.
    WRITE: / `I'm a concrete method`.
ENDMETHOD.                    "concrete
ENDCLASS.                    "gcl_abstract IMPLEMENTATION
*       CLASS gcl_abstract_sub DEFINITION
CLASS gcl_abstract_sub DEFINITION INHERITING FROM gcl_abstract.
PUBLIC SECTION.
    METHODS concrete REDEFINITION.
ENDCLASS.                    "gcl_abstract_sub DEFINITION
*       CLASS gcl_abstract_sub IMPLEMENTATION
CLASS gcl_abstract_sub IMPLEMENTATION.
METHOD concrete.
    super->concrete( ).
    WRITE: / 'Abstract class might not have abstract methods at all!'.
ENDMETHOD.                    "concrete
ENDCLASS.                    "gcl_abstract_sub IMPLEMENTATION
START-OF-SELECTION.
DATA: go_abstract TYPE REF TO gcl_abstract_sub.
CREATE OBJECT go_abstract.
go_abstract->concrete( ).
Although i will agree there is no point in making a class as abstract & having no abstract method
@Sri: Looks like you're trying to implement the abstract method "AREA" in the abstract class hence the error. For abstract method you cannot define their implementation in the corres. abstract class.

Oh, I see that the title of your post is an error message? Ok. Well, the test class is declared as implementing an ActionListener. That means the test class must have an actionPerformed() method. Your test class apparently does not.
It does not appear that the test class needs to implement ActionListener. You are using annonymous classes as listeners.

I will remove all the gui code to make it shorter, but my problem lies with my InteractiveTableModelListener.

Sorry, just figured out my silly error, the method is tableChanged not TableChanged.

According to the book I'm reading, if you merely take
out the generic from the code, it should compile and
run in v1.4 (assuming, of course, that the class
exists in 1.4). I don't know what book you are reading but that's certainly incorrect or incomplete at least. I've manually retrofitted code to 1.4, and you'll be inserting casts as well as replacing type references with Object (or the erased type, to be more precise).
These interfaces do exist in 1.4, and
without the generics.Exactly. Which means compareTo takes an Object, and you should change your overriding method accordingly.
But this raises a new question: how does my 1.4
compiler know anything about generics? It doesn't and it can't. As the compiler is telling you, those interfaces expect Object. Think about it, you want to implement one interface which declares a method argument type of Object, in several classes, each with a different type. Obviously all of those are not valid overrides.

Hi,
did you provide your credential during the Adobe installation process (as far as I know, you have to install the Adobe Document and not only deploy these).
You have to provide the credential and enter a password during the process, or it does not work.
The last info I have is that you get credentials by entering a customer request at SAP, component BC-SRV-FP, but that might have changed...
Kind regards,
Carl

Hi Namit,
Have you installed a credential file to your ADSServer?
This is required to apply the usageRights onto the PDF.
You need to install the ReaderRights credential file. Follow the steps from this URL:
Re: Interactive form application error
Make sure that the password and the expiry date of the ReaderRights credential file are valid.
Hope this helps.

The statement is
     TABLE.id = 1;
     TABLE.contenido =     at.contents
     store(TABLE)
also tried:
params as Any[] = []
params[] = 1
params[] = Binary(data : at.contents).data
retVal as Int
query as String = "INSERT INTO TABLE(id, contenido) VALUES (?,?)"
extResource as String = "db"
retVal = executeUpdate(DynamicSQL, sentence : query,
implname : extResource,
inParameters : params)
and the result was the same.
The select statments works fine.
Any idea???
I'm working with Studio Version: 10.3.2 Build: #100524

How to declare abstract method

given - work worked at first .
fact - then i went to add new entity object names ScottOafE0 . went through all the next sand finished. a package and entity obj already exist. i also tried to put a new package and ScottOafAM in a seperate place. still a no go
when i went to run the form it errors out w/ below msg.
Error(14,8): class xxxoaf.oracle.apps.xxuab.hr.newforms.server.ScottOafEOImpl should be declared abstract; it does not define method setLastUpdateLogin(oracle.jbo.domain.Number) in class oracle.apps.fnd.framework.server.OAEntityImpl
Guess - i tired to put import oracle.apps.fnd.framework.server.OAEntityImpl in the controller file . didnt work
any idea how to define abstract method ?
thanks
scott

You dont need to define your class as abstract, that would not resolve your issue, what is happening is
oracle.apps.fnd.framework.server.OAEntityImpl is a abstract class, and has a method declared as setLastUpdateLogin(oracle.jbo.domain.Number) in class
Now, any class (xxxoaf.oracle.apps.xxuab.hr.newforms.server.ScottOafEOImpl ) extending from this class must either provide a definition to this method (provide the implementation logic), or must itself be declared abstract.
We had a discussion on this issue in the forum , look for the thread.
Thanks

Abstract Method Overriding Problem

I have an abstract class called "Employee" with an abstract method called "ReturnBasicInfo()" defined.
I have two subclasses, SalariedEmployee and HourlyEmployee, and each has their own version of ReturnBasicInfo(). The compiler is not letting me do this, however, and I have no idea why.
I keep getting this error:
SalariedEmployee.java:6: SalariedEmployee is not abstract and does not override
abstract method returnBasicInfo() in Employee.The abstract method signature is this:
public abstract String returnBasicInfo(Employee e);Any idea why this might be happening? I have another abstract method called toVector() that's overriden in the subclasses and that one works fine, so I'm stumped on this. The only difference between the two is that this method takes arguments and the other doesn't. Is that why it can't be overriden?
Thanks in advance for any help!

"...In the instructor's example code, he actually
overrode toString with this method. I thought I might
be using the real toString(), though, so that's why I
changed the name to returnBasicInfo(). I didn't end up
using toString(), though. Maybe I ought to go back to
calling it toString()..."
Yes, this SHOULD be overridden in toString(). Do go
back to it.
The "real" toString()? Do you mean the default
version in java.lang.Object, the one that just prints
out the object reference when it's called?
Hmm, I guess. I got confused because I'm swapping between String and double values a lot. Taking in an entered number as a String and converting it to a double.
I think I originally confused toString() with String.valueOf().
I wouldn't have getYearlySalary() for SalariedEmployee
and getHourlySalary() for HourlyEmployee. That
defeats the purpose of polymorphism and dynamic
typing. Yes, but I do have one polymorphic method --pay(). Each Employee is paid a different way. The one method we were supposed to be able to call on all Employees is just pay(). There is one version of pay() for HourlyEmployees that uses gethourly_rate() and gethours_worked() to get hourly rate and hours worked. The other version of pay() in SalariedEmployees takes in their yearly salary and number of pay periods worked.
Better to have a getSalary() method in your
Employee interface and let each subclass implement it
the way they want to. SalariedEmployee will return
their yearly salary, HourlyEmployee will return
hourlySalary*hoursWorkedOK, that's one idea.
But darnit, I would still like to know how to get my original design to work. So I should change returnBasicInfo() to toString(), you think?
