Lion will not install, says HD must be extended (Journaled). The HD is extended
I cannot install Lion because the dialog box says my HD is not Mac OS Extended(Journal). I look at the hard drive in disk utility. It appears to be an Mac OS Extended. Do you have to turn journaling, if so how?
Thanks,
Bill Wallace# sudo diskutil enableJournal <device>
Edit: Should have added that you need to use Terminal.app. You will need to find the device name first.

Find the volume name you want to use, and use that device for the above command.

In order to manage OHS through em console, the weblogic domain must be extended by Enterprise Manager and JRF. After the extension, you can associate the OHS instance with the weblogic server and manage it with the help of em console. -

You can savely ignore the message JAG-00025 - [Service: eHRPService] - applicationModule must (indirectly) extend JHeadstart's JhsApplicationModuleImpl or RuleFrameApplicationModuleImpl.
This message is also given when you indirectly extend JhsApplicationModuleImpl. We have fixed this in the upcoming release.
The error that you cannot make a connection usually indicates that your database connect information in cle-providers.xml is wrong. Can you check cle-providers.xml, and confirm that database is up and that you can connect to the specified user?

Link between Accounting Document and Sales Order
Dear SD Gurus,
How to find the Sales Order number and Sales Order Item from the accounting document- like document types DZ, DG, ID etc.
Kindly specify the table links and fields to fetch the above details
Regards
VimalLink Between SAP SD, MM & FI
The link between SD and MM :-
1. When you create sales order in SD, all the details of the items are copied from Material master of MM.
2. MRP and availibility check related data is also taken from MM although you control this data in SD also.
3. While you create inbound/outbound delivery with reference to a sales order,the shipping point determination takes place with the help of the loading group, plant data, shipping conditions etc. This also refers to Material Master.
4. The material which you are entering in a sales order must be extended to the sales area of your sales order/customer otherwise you cannot transact with this material.
There are many such links between SD and MM.
Now the link between SD and FI :-
1. Whenever you create a delivery with reference to a sales order, goods movement takes place in the bacgground. eg. In case of standard sales order, you create an outbound goods delivery to the customer.
Here movement 601 takes place. This movement is configured in MM. Also, this movement hits some G/L account in FI. Every such movement of good s hits some G/L account.
2. The accounts posting in FI is done with reference to the billing documents (invoice, debit note, credit note etc) created in SD. Thus this is a link between SD and FI
3. Tax determination: In case of a tax determination also, there is a direct link between SD and MM

Client certificate authentication with custom authorization for J2EE roles?
We have a Java application deployed on Sun Java Web Server 7.0u2 where we would like to secure it with client certificates, and a custom mapping of subject DNs onto J2EE roles (e.g., "visitor", "registered-user", "admin"). If we our web.xml includes:
<login-config>
<auth-method>CLIENT-CERT</auth-method>
<realm-name>certificate</realm-name>
<login-config>that will enforce that only users with valid client certs can access our app, but I don't see any hook for mapping different roles. Is there one? Can anyone point to documentation, or an example?
On the other hand, if we wanted to create a custom realm, the only documentation I have found is the sample JDBCRealm, which includes extending IASPasswordLoginModule. In our case, we wouldn't want to prompt for a password, we would want to examine the client certificate, so we would want to extend some base class higher up the hierarchy. I'm not sure whether I can provide any class that implements javax.security.auth.spi.LoginModule, or whether the WebServer requires it to implement or extend something more specific. It would be ideal if there were an IASCertificateLoginModule that handled the certificate authentication, and allowed me to access the subject DN info from the certificate (e.g., thru a javax.security.auth.Subject) and cache group info to support a specialized IASRealm::getGroupNames(string user) method for authorization. In a case like that, I'm not sure whether the web.xml should be:
<login-config>
<auth-method>CLIENT-CERT</auth-method>
<realm-name>MyRealm</realm-name>
<login-config>or:
<login-config>
<auth-method>MyRealm</auth-method>
<login-config>Anybody done anything like this before?
--ThanksWe have JDBCRealm.java and JDBCLoginModule.java in <ws-install-dir>/samples/java/webapps/security/jdbcrealm/src/samples/security/jdbcrealm. I think we need to tweak it to suite our needs :

How can provide parent-child nodes relation ships?
how can provide parent-child nodes relation ships?
I was under the impression that scenegraph is like a JTree. But in JavaFX only leaf node rendering in scenegraph. This situation was confusing my mind. In JavaFX CustomNode must be extending and return a group for custom leaf. If we want to a create parent-child node hierarchy we are create CustomNode that return a group and this group contain an another group,etc. So there is maybe only a way. If you learning to JavaFX first time.This way don't look familiar.

J2Se receiver File adapter-HTTP 503 no listener registered for service
Hi,
We are using J2Se file adapter for one the interfaces and the logs of the J2se adapter engine has shown the following error-
Error: com.sap.aii.messaging.net.TransportException: HTTP 503 no listener registered for service /file/example_outbound
at com.sap.aii.messaging.net.HTTPRequest.run(ServerHttpImpl.java:416)
I checked with the J2SE File/FTP receiver adapter configuration given at help.sap and found the following the following info related to the error-
Specifications for addressing by the Integration Engine
○ XI.httpPort=<port_no>
<port_no>specifies the HTTP server port that receives the messages from the Integration Engine.
○ XI.httpService=<service>
<service> describes the service part of the address where the Integration Engine must send its messages.
These specifications are mandatory.
If, for example, you have specified XI.httpPort=1234 and XI.httpService=/file/Receiver, the end point address of the file/FTP adapter in the Integration Engine must be specified as follows:
http://<fileadapterhost>:1234/file/Receiver
The end point address must be extended as follows for the Integration Engine in Release 1.0:
http://<fileadapterhost>:1234/file/Receiver?action=execute&pipelineid=Receiver
If the Integration Engine message is sent to a non-specified adapter service, the system displays the following error message:
*No registered listener for <Service> found*
The system displays the same message if the adapter is initialized, but has not been started (status STOPPED or INITIALIZED).
Where I need to check this Integration engine address specifications. I have't found any of the above code in the adapter configuration which we are using presently.The interface is running successfully before but thrown this error now.
Please reply me if some one has faced similar issue and get it resolved.Hi
How was this issue resolved? I have the same problem.
I only have two receivers - the deafult j2se file receiver and my newly created one which used the default as a template. The ports and service's are different.
I've even tried deleting my custom receive adapter and using only the default one but i still get that error. -
I am new to Java and for some reason I can't get my head around why to use an abstract class. I understand that an abstract class is something like:
public abstract class Food{ // abstract class
public void eat(){
// stub
public class Apple extends Food{
public void eat(){
// Eat an apple code
}So basically the idea above is that you can eat an "apple" but you can't eat "food" because you can't instantiate an abstract class.
I understand what an abstract class is and how to write one. What I don't understand is why you would use it? It looks to me like I could have just created a normal class called "Food" and just not instantiated it. What are the benefits of using an abstract class?807479 wrote:
I am new to Java and for some reason I can't get my head around why to use an abstract class.One of the first books I ever read about Object-Oriented design contained the following quote from [url http://en.wikipedia.org/wiki/Lucius_Cary,_2nd_Viscount_Falkland]Lord Falkland:
"When it is not necessary to make a decision, it is necessary +not+ to make a decision."
It took me quite a while to understand, but it's all about flexibility: As soon as you cast something in stone, you lose the ability to change it later on if something better/more appropriate comes along. Interfaces and abstract classes are all about delaying that decision.
As jverd said, interfaces allow you to specify what is required without defining the how; and as ErasP said, abstract classes are usually incomplete: ie, they define some of the 'how', but not all of it.
What is most important about abstract classes though is that they cannot exist on their own: They must be extended by a concrete class that completes the 'how' before they can be instantiated and, as such, they declare the intent of the designer.
One of the most important uses of abstract classes is as "skeleton implementations" of interfaces, and there are a lot of examples of these in the Java Collections hierarchy. My favourite is probably AbstractList, which contains a skeleton implementation of a List. Because it exists, I can create a class that wraps an array as a List with very little code, viz:public final class ArrayAsList<T>()
extends AbstractList<T>
private final T[] values;
public ArrayAsList(T... values) {
this.values = values;
@Override
public T get(int index) {
return values[index];
@Override
public T set(int index, T element) {
T value = get(index);
values[index] = element;
return value;
@Override
public int size() {
return values.length;
};and somewhere else, I can use it: List<String> letters =
new ArrayAsList<String>("a", "b", "c");or perhaps, more practically: List<String> words = new ArrayAsList<String>(
bigTextString.split(" +") );Now that may not seem like a big deal to you, but given all that Lists can do, it's actually a very powerful bit of code. The above example is from "Effective Java" (p.95).

Is there a problem with Java forums
I am just checking
Java has yet another security vulnerability. Details on exactly which versions of Java are sketchy at this point, but all versions of Java 7 from Oracle are... if you have such a version of Java, turn off Java in your web browser ASAP!
Of course, both Apple and Mozilla have acted quickly to disable all versions of Java up to the latest version of Java 7. The only way you'll get a Java applet working with Safar or Firefox is to wait for Oracle to update Java, or if you take certain other unsafe procedures to get a vulnerable version of Java working again.
Kudos must be extended to both Apple and Mozilla in this case for making a choice that has made some users angry. This vulnerability was being actively exploited to drop malware onto Windows users' systems, and it was just a matter of time before Mac users were similarly affected. The fact that they acted so quickly to protect users from this threat shows that security is of utmost importance to both companies. -
I'm trying to create a form that can be filled in by clients who have only the free Reader, saved, and sent back to us as a pdf. It seems to work when the files are opened with Preview on the Mac, but when people open it in Acrobat Reader they get the message that data can be entered but not saved. What am I doing wrong?
Document properties assures me that "Filling in Form data" is "allowed" in the document.Using Acrobat 8 Pro or 3D you must first "Enable..." the PDF (in the Advanced menu drop-down).
Using Acrobat 9 Pro or Pro Extended you must first "Extend..." the PDF (in the Advanced menu drop-down)

How to know if a scrollbar is been drawn if the JScrollPane is not visible.
I have a JTabbedPane with one JPanel in each tab. Each of these panels contains one JLabel with a JTextBox on the top and under it the rest is filled with a JScrollPane containing a JTable. I am using a GridBagLayout.
Now, the requirement is that the JTextBox must have the same length as the content of the JScrollPane; it means that if the JScrollPane has a vertical scroll, the JText has to be shorter on the right side by whatever the scroll width is, but if there's no vertical scroll then the JTextBox must be extended to the top of the right side.
Now, this that looks so simple is becoming a nightmare...
The main problem here is that this check to look if the JScrollPane has a scroll or not is done in tabs that are not visible, so i cannot use just a simple isVerticalScrollVisible() because the answer is always NO. I have been trying to catch all the events i could think may help but no luck and sometimes a refresh in one of the tabs produces the JTextField in another tab gets a wrong width.
One posible approach is the length of the total rows of the JTable, multiply it by the row height and compare it with... with what because the scroll is not visible and the heigh is 0.
Any ideas? Any one knows how can i know if the the silly scrollbar is visible or not in a non visible tab?
Thanks in advance.Note: This thread was originally posted in the [Java Programming|http://forums.sun.com/forum.jspa?forumID=31] forum, but moved to this forum for closer topic alignment.

chandra.Hi Chandra,
1. When you create sales order in SD, all the details of
the items are copied from Material master of MM.
2. MRP and availibility check related data is also taken
from MM although you control this data in SD also.
3. While you create inbound/outbound delivery with
reference to a sales order,the shipping point determination
takes place with the help of the loading group, plant data,
shipping conditions etc. This also refers to Material
Master.
4. The material which you are entering in a sales order
must be extended to the sales area of your sales
order/customer otherwise you cannot transact with this
material.
There are many such links between SD and MM.
Now the link between SD and FI :-
1. Whenever you create a delivery with reference to a sales
order, goods movement takes place in the background. eg. In
case of standard sales order, you create an outbound goods
delivery to the customer.
Here movement 601 takes place. This movement is configured
in MM. Also, this movement hits some G/L account in FI.
Every such movement of goods hits some G/L account.
2. The accounts posting in FI is done with reference to the
billing documents (invoice, debit note, credit note etc)
created in SD. Thus this is a link between SD and FI
3. Tax determination: In case of a tax determination also,
there is a direct link between SD and MM
SD Integration points with other modules
SD module is highly integrated with the other modules in
SAP.

In Business We wud want to post the revenues or the
discoutns offered, taxes collected, Freight charges to a
particualr GL accoutn for accouting purposes. Lets say i
want to accoutn for all the revenuses i generated for
finished goods. I wud use this Finished goods as the
Material Accoutn assignment group and assign that in the
Sales org 2 view just above the Item cat group. Then with
Accoutn determination process i wud link the Account Key
ERL (In Pricing proc) + Finished Goods (Material Accoutn
Aiisgment grp) -
TO A GL ACCOUNT. Thts SD-FI
integration.
SD MM.
In Pricing we wud want to determine the cost of the product
thru VPRS Condition Type. This cost of the material is
picked from the Material Master. How this happens is , if
we wud want to determine this cost VPRS in the Sales Order
for Profitability purpose then , all those Item cateogries
tht can appear in a sales order must be activated for
Detemine Cost Check box in customizing. Thts one of the SD
MM Integration.
Assign points if useful
