The serializable class SpacePainter does not declare a static final serial
The serializable class SpacePainter does not declare a static final serialVersionUID field of type longWhat does this mean??? It appears as a warning in Eclipse but I have no idea what it is. It happens when I create a class the extends JFrame or JCompnent or JApplet. I finnally got it to stop with this:
static final long serialVersionUID = 1;
Because your eclipse is configured that way. You can probably filter the warning. You don't have to implement the serialVersionUID, but you should if you really serialize the exceptions.

ERROR: serializable class HelloComponent does not declare a static final
Hi everyone! I'm sorry but I'm a newbie to Java and I'm having some, I assume, basic problems learning to compile and run with javac. Here is my code:
import javax.swing.* ;
import java.awt.* ;
public class MyJava {
* @param args
public static void main(String[] args)
// TODO Auto-generated method stub
JFrame frame = new JFrame( "HelloJava" ) ;
HelloComponent hello = new HelloComponent() ;
frame.add( hello ) ;
frame.setSize( 300, 300 ) ;
frame.setVisible( true ) ;
class HelloComponent extends JComponent
public void paintComponent( Graphics g )
g.drawString( "Hello Java it's me!", 125, 95 ) ;
And here is the error:
1. WARNING in HelloJava.java
(at line 20)
class HelloComponent extends JComponent {
^^^^^^^^^^^^^^
The serializable class HelloComponent does not declare a static final serialVersionUID field of type long
ANY HELP WOULD BE GREAT! THANKS! =)Every time I extend GameLoop, it gives me the warning
serializable class X does not declare a static final serialVersionUID field of type long
This is just a warning. You do not need to fix this because the class you are writing will never be serialized by the gaming engine. If you really want the warning to go away, add the code to your class:
static final long serialVersionUID=0; -

Object class name does not exist in IDM
Hi Team
We are process of Integrating GRC 10.1 to Enterprise Portal.Followed accordingly as per the SAP Note No. 1977781.
While running the Schema Job, we get a message Schema Imported Suxcessfully. While running the Job : GRAC_REPOSITORY_SYNC_JOB, the job
shows successful, but a Warning Message : User Adaptor Empty in SLG1 T.code.
I have checked the Path suffix,connectors,data source and all are maintained but no sure about this warning message.
Secondly,I tried for test creation of user on Portal via GRC 10.1.I am getting below error
"Object class name does not exist in IDM" Please see log below
Request gets closed stating Auto Provisioning failed.Please advice if someone has faced same issue and the steps taken to rectify it.
Thanks
NiteshHi Nitesh,
We worked on this issue for quiet sometime with SAP to get this finally fixed You can check all below mentioned notes.
First Check:
Please check the Note: 1915763 - Error Provisioning from GRC 10 to SAP Portal while adding or removing a role in Change Account request type.
This Note says that if your LDAP set as data source is read-only in Portal, then you need to change it to Modifiable in order to allow create or change user belonging to LDAP.
We have set the UME correctly and no longer read-only. But our access requests still used to fail with the following messages.
"Object class name does not exist in IDM".
Second Check:
Kindly ensure the field mapping for portal is done in IMG settings properly.
If it is fine please check below note 2033714 - AC10.0: error in SGL1 "Object class name does not exist in IDM".
This note is only to check if you have made any mistake with your portal mapping and doesn't address the correct issue.
Third Check:
Finally after implementing SAP note 1941250 - UAM: Truncated parameters provisioned on changing users from Access Request
our issue got fixed.

Madhu. -
The selected context node does not have attributes - Message no. SWDP_WB_TO
Hello,
I am trying out the example in web dynpro documentation -> Creating a Simple Flight Info Application
and in part 3 steps 11 - 13 I get the following error
The selected context node does not have attributes
and the associated message class and # is :
Message no. SWDP_WB_TOOL467
can anyone please help ?Hi Raj,
Have you done the steps 7 and 8 as described
7. Create an additional node called u201CflightSu201D, this time with the cardinality 0..n.
8. Use the Create Using Wizard option of the context node again to define attributes from the SFLIGHT structure for this new node (see part 1, step 15). Choose the following fields: CARRID, CONNID, FLDATE, PRICE and PLANETYPE.
See the flights node , if there are no attributes the perform the steps as described in 8. -

There is a problem in batch determination.
The batch you assigned to the material does not have a class or if it has a class, that class does not exist.
Display the batch from the delivery item using MSC3N and go into the Classification tab. You should have a class of class type 22. See if that class exists in CL03 and its status in basic data tab. Work on these lines and revert.
Hope this helps. -
Class CL_RSR_QUERY_VARIABLES does not exit anymore
Dear all,
Class CL_RSR_QUERY_VARIABLES does not exist anymore in NW04s. Does anybody know what is the new class that substitutes it?
Thanks and regards,
Flavia SanchezHi Michael,
I am the guy responsible for this development.
The class is used in a function module to execute a BW Query and return a xml string within a BSP application. The result table of the query is used within the BSP application logic to fill the graphical presentation layer that consitutes the front end of the BSP application.
Here is the statement within the FM where the class is used:
DATA: wf_query_var TYPE REF TO cl_rsr_query_variables .
Here is the call to the FM within the BSP application (Even Handler: OnInputProcessing):
CALL FUNCTION 'Z_RMZ_BW_SEM_NGRM_EXE_QRY'
EXPORTING
QUERY_NAME = rpt_tech_id
IMPORTING
XML_OUT = xml_out
REF_RESULT_TAB = res_tab
TABLES
QUERY_VARIABLES = var
RETURN = breturn
META = meta
EXCEPTIONS
BAD_VALUE_COMBINATION = 1
USER_NOT_AUTHORIZED = 2
UNKNOWN_ERROR = 3
QUERY_NOT_FOUND = 4
OTHERS = 5.
If this class does not exist with this name in NW then I assume it must exist as another object since this is THE class for programming with query variables.
Thanks for your support.
Greetings,

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

Indeed, I just put a.jar and b.jar in application directory.

Can I convert a proxy for a class that does not has any interfaces?
Can I convert a proxy for a class that does not has any interfaces?
Hi.
I can hardly understand your question: what do you want your proxy (what kind of proxy?) to be converted into?
All I can tell you is the following: Proxies created using java.lang.reflect.Proxy can only be created using an interface. This interface has to be implemented by the proxied object. So: no interface, no java.lang.reflect.Proxy.
Bye. -

Mac Pro Mac OS X (10.4.9) 8-core, x1900 vidHi Jeff,
> Well, geometric algebra need not encompass the
whole of Clifford algebras in order to be a development
in the field.
Of course I'm not saying that Geometric Algebra must contain the entirety of the theory of Clifford Algebras in order to be a development in the area. I'm saying that it must leave the confines of that area to be a development. I'm sure you've encountered the word "subset" in the math you've already studied. There is nothing in the definition of a subset about how much of the parent set that the subset should contain. The only requirement of a subset is that it cannot leave the confines of the parent set. I don't care how much of the original theory is omitted, I'm just saying that there exists nothing outside of the original theory.
> Are you saying the work being done is entirely redundant
and should perhaps be abandoned for what's already
been done in studying Clifford algebras and their
generalizations?
Now you're addressing the meaning of my statements; "Entirely redundant" does characterize a subset so yes, that is what I'm saying. However, you then read in additional meaning. No, I'm not saying that it should be abandoned. I tried to devote half of the original post to saying that a rose by any other name ...
> Perhaps it's just the way you express yourself, but
this topic does seem like it hits a nerve with you
You are correct. I excluded my perception of plagiarism from the set of statements that I claim to be factual but it's difficult to hide my strong emotional response to that. I agree with everything you say about reformulations but there are right ways and wrong ways to do that. Consider the following search, Google search: Clifford site:geometricalgebra.org, for the word "Clifford" on their website. The only places it appears is in source code and then it is merely a reference to a conjugation operator. There is no mention of Clifford Algebras on their website. The right way would be to state the situation up front.
I apologize for inflicting my emotional baggage on you. All I really wanted to do is to warn you. You have exactly the right attitude. I envy the sense of wonder and discovery that you now enjoy and the last thing I want to do is to dampen that. In fact, what I would most like to convey is that that feeling shouldn't diminish as you continue. What I fear and want to prepare you for is that when you are ready to branch out and learn the math, it will likely be more difficult than it should be because they haven't given the math foundation that you would need. My fear is that you might get the impression that the math itself is more difficult than it is. I don't want frustration to hinder your efforts to learn.
You have a great attitude now. I'm convinced that you sense the power and the beauty of the subject. As long as you resist frustration and continue to learn, you should be fine. I assure you that the subject is worth any and all effort that you put into it.
Gary
