Hello Everyone,
My name is Prashant Sharma from Jaipur [Rajasthan]
Can u people help me
How to create of one class into another and vice versa
Eg,
I am having class A and class B
I want to create object of class A into class B and vice versa
Plz help me out of this problem as soon as possible....

Read this: [Creating Objects|http://java.sun.com/docs/books/tutorial/java/javaOO/objectcreation.html]
Then, do one of these three:
1. Create an instance of the class
2. Extend the class
3. Access methods within the class
Try it out. Post the problem code if you're having trouble.

How do i Drag and drop From one tree to another and vise versa?

I have two tree structures and i'm trying to drag a leaf of a branch from one tree to another and vise versa. i'm using flex 3 to code it. I'm also trying to put a prevention on dropping a leaf of one tree from being dropped inside a branch of another tree. Anything that is dragged over to another tree should be placed as a dangling node in that tree. Please share this code and help me find a solution.

Yes, I have set dragEnabled and dropEnabled to true. I trying to put restriction on dropping the node(aka leaf) of 1st free tree inside the branch(aka folder) of the 2nd tree. If something is dragged from tree1, it should be dropped only on tree2 i.e., dragged node should be appended at the end of tree2 and not inside nay of the branches of tree2. This functionality should work on both the trees. I'll be glad if u can provide the solution.

How to convert ascii value into character and vice versa

Hello the java world people,
I want to convert each characters from my array into their corespondent ascii value and vice versa, how can I do that ?

The term "ASCII" is often used very loosely.
Java char values are UNICODE and the ASCII codes are indentical to UNICODE characters in the range 0 .. 127. UNICODE values 128 and above don't have coresponding ASCII values, though 128-255 corespond to ISO-8859-1 which is one of the encodings often called "extended ASCII".
As shown above you can covert between chars and coresponding int value simply with a cast, but you should be aware that the more exotic characters will not give you sensible values.

Connecting multiple CRM systems to one backend R/3 and vice versa

Hello experts
Can you tell me whether it is advisable to connect 2 CRM systems to a single backend R/3 and vice versa? Is it recommended by SAP? I require some notes or docs on this. I got some notes on this forum but they are all Internal ones which I am unable to see.
Please help!
Warm Regards
Debolina

Hi,
Though SAP does not recommend connecting multiple systems to one ECC backend. But still it has designed a procedure to achieve this.
Here is the excerpts of the steps required.
1. Execute report MCRM_SETTINGS for each CRM system connected to the ERP
system.
2. Check the entries of the table CRMRFCPAR of the connected ERP system:
The field REM_LOGSYS should be filled for every entry marked with
u2018Created by the MCRM reportu2019.
3. Activate the corresponding consumers in the table CRMCONSUM
(transaction SM30).
4. Internal and external number ranges for Business Partners have to be aligned
manually.
Hope it helps you!!!!
Good Luck.

How to override attributes of one class into another class in OOPS ABAP

I was trying to override attribute(data memeber) defined in super class into subclass ,
but I didnt find any solution to that.
Please tell me ho to do that?
Ex
Class ABC definition
      Public section
         data : x type i.
   end class
Calss XYZ definition inheriting from ABC.
    Publec section.
       data : x type i.                                            <<----
here is the problem
endclass.

when you define a subclass all the properties of superclass are inherited into class.
You dont need to define it again.
data : x type i " delete this line.
Object of your subclass will be able to recognize x.

PSE12 Organizer - can you copy photo from one folder to another and import copy into Organizer and still have original in other folder

I have been using folders to organize all my pictures and I will copy photos from folder to folder, often having them in 2 or 3 folders based on use. I tried to copy a photo in Organizer PSE12 from one folder to another and you can only move it, that means I can only have one copy of the photo. That is fine if I am using tags and want to search for it, but I want to have mult copies in mult folders. Organizer will recognize that it is there but it won't import it into the new folder. Until I move it, it stays in the original folder. I can drag it out of Organizer and drop (copy) it into a new folder fine, but it won't show in organizer in the new folder. Is there any way to copy and have multiple copies show up in multiple folders?

Hi,
The organizer works on the principle of not having multiple copies of the same photo.
If you have multiple copies spread in different folders, then making changes to one doesn't affect the others. The use of tags and albums are there to give different views of your photos.
You can't have multiple copies with exactly the same name even if they are in different folders. You could select a photo and duplicate it (File -> Duplicate) and then move the copy into a different folder but the name will be different.
If you want different folders for a specific reason, it is possible to use albums to collect the group of photos and then export them to a new folder outside of the organizer. You can also rename on export which is useful if you want to arrange the photos in a specific order.
Hope that helps a bit.

How do I move an object from one photo to another and then change the scene, i.e. winter to sum?

How do I move an object from one photo to another and then change the scene, i.e. winter to summer?

OK.
Open the picture with the new scene. This will be your canvas.
Open the picture with object A, select it with one of the selection tools, go to Edit>copy
Go back to the new scene/canvas, Go to Edit>paste
Repeat for object B
Use the move tool to position A & B, each on its own layer. Use the corner handles of the bounding box to resize, if necessary
You should have 3 layers: Background layer, and the 2 layers with A & B
Note: It's best if the resolution of the 3 picture files is the same value.

I would like to copy all the songs from one Ipod into another. All the songs are into my Itunes account, I tried to drag and drop the songs from the old Ipod to the new one but it doesn't work. Is there a way to do it ?

Hello everybody,
I would like to copy all the songs from one Ipod into another. All the songs are into my Itunes account, I tried to drag and drop the songs from the old Ipod to the new one but it doesn't work. Is there a way to do it ?
I share one Itunes account with other people from my family and one person would like to keep the same songs on the new Ipod as the ones which were on the old one.
Thanks in advance for your answer.

Hello Chris,
Thanks for your answer. I was hoping for an easier answer. Too bad there is no drag and drop solution, it would have been much easier.
Thanks for answering so fast.
Bye.

Images I move from one folder into another are disappearing, at first it was occurring immediately if I did not copy and paste the images. Today however I found out that images I had been using for days just up and vanished from their new location.

Images I move from one folder into another are disappearing, at first it was occurring immediately and only if I did not copy and paste the images. Today however I found out that images I had been using for days just up and vanished from their new location. A few of these images had copies in another folder that remained and the ones I couldn't find may or may not have ever had copies. I had backed up my system with time machine recently as well, so I went into the backup to retreive the lost images. When I searched and found the backup copies I got the error "the file alias cannot be opened because the original cannot be located". The crazy thing is that the images that remained on my computer did not give me the same error and opened like they should.
In short images that I am creating, saving, and using are disapearing so epically that even time machine versions are affected when retrieval is attempted. Any suggestions as to what I could be doing wrong without realizing it? Or perhaps other people have had similar bugs that are software related and have a solution?

Hi Kevin,
I understand what you tried to do but it doesn't work that way. Swapping drive names will just mess things up.
You should be able to reconnect the files though: in the Locate Referenced Files dialog make sure you click the Show Reconnect Options button — this will give you access to all the connected drives. Locate one of the files and hit Reconnect All. Should do the trick.
Best

I dragged a cut out image from one photoshop document into another and now it is blurry. What to do?

I dragged a cut out image from one photoshop document into another and now it is blurry. What can I do to prevent this?

What is the resolution of the image that you "dragged"? The resolution is the number in pixels per inch (ppi). If you dragged a significantly lower resolution file into a higher resolution file, it could result in a blurry image.
see below:
For further reading of Key Concepts:
http://www.adobe.com/designcenter-archive/keyconcepts/articles/concept_resolution.html
You can determine the image size by choosing Image > Image Size
below you can see the pixel dimensions of my example image.

How to transter contents of itab from one class to another...

Hello experts,
I am currently having problems on how to transfer the contents of an itab or even
the value of a variable from one class to another. For example, I have 10 records
in it_spfli in class 1 and when I loop at it_spfli in the method of class 2 it has no records!
This is an example:
class lcl_one definition.
public section.
data: gt_spfli type table of spfli.
methods get_data.
endclass.
class lcl_one implementation.
method get_data.
select * from spfli
into table gt_spfli.
endmethod.
endclass.
class lcl_two definition inheriting from lcl_one.
public section.
methods loop_at_itab.
endclass.
class lcl_two implementation.
method loop_at_itab.
field-symbols: <fs_spfli> like line of gt_spfli.
loop at gt_spfli assigning <fs_spfli>.
   write: / <fs_spfli>-carrid.
endloop.
endmethod.
endclass.
start-of-selection.
data: one type ref to lcl_one,
      two type ref to lcl_two.
create object: one, two.
call method one->get_data.
call method two->loop_at_itab.
In the example above, the contents of gt_spfli in class lcl_two is empty
even though it has records in class lcl_one. Help would be appreciated.
Thanks a lot guys and take care!

Passing Variables from One Class to Another

Hello, I am new to Java Programming and I'm currently starting off by trying to build a simple application.
I need help to pass variables created in one class to another.
In my source package, I created 2 java classes.
1. Main.java
2. InputFileDeclared.java
InputFileDeclared reads numerical data from an external text file and store them as string variables within the main method while Main converts a text string into a number.
Hence, I would like to pass these strings variables from the InputFileDeclared class to the Main class so that they can be converted into numbers.
I hope somebody out there may enlighten me on this.
Thank you very much in advance!

Values are passed from method to method, rather than from class to class. In a case such as you describe the code of a method in Main will probably call a method in InputFileDeclared which will return the String you want. The method in Main stores that in a local variable and processes it. It really doesn't matter here which class the method is in.
You InputFileDeclared object probably contains "state" information in its fields such as the details of the file it's reading and how far it's got, but generally the calling method in Main won't need to know about this state, just the last data read.
So the sequence in the method in Main will be:
1) Create an new instance of InputFileDeclared, probably passing it the file path etc..
2) Repeatedly call a method on that instance to return data values, until the method signals that it's reached the end of file, e.g. by returning a null String.
3) Probably call a "close()" method on the instance, which you should have written to close the file.

Calling a drawLine() from one class to another from an ActionEvent

I have several JPanel objects called and placed on a JFrame. The JFrame has a RadioButton group with radio buttons. If I select a radio button and call a drawLine() method from a JPanel, I receive a "NullPointerException". Is it not possible to call this graphic method from one class to another?
Thanks for any input you can provide.
John

Remember that each panel draws it's own current state. So you need the ActionPerformed to change the state in your target panel.

Passing a parameter from one class to another class in the same package

Hi.
I am trying to pass a parameter from one class to another class with in a package.And i am Getting the variable as null every time.In the code there is two classes.
i. BugWatcherAction.java
ii.BugWatcherRefreshAction.Java.
We have implemented caching in the front-end level.But according to the business logic we need to clear the cache and again have to access the database after some actions are happened.There are another class file called BugwatcherPortletContent.java.
So, we are dealing with three java files.The database interaction is taken care by the portletContent.java file.Below I am giving the code for the perticular function in the bugwatcherPortletContent.java:
==============================================================
public Object loadContent() throws Exception {
Hashtable htStore = new Hashtable();
JetspeedRunData rundata = this.getInputData();
String pId = this.getPorletId();
PortalLogger.logDebug(" in the portlet content: "+pId);
pId1=pId;//done by sraha
htStore.put("PortletId", pId);
htStore.put("BW_HOME_URL",CommonUtil.getMessage("BW.Home.Url"));
htStore.put("BW_BUGVIEW_URL",CommonUtil.getMessage("BW.BugView.Url"));
HttpServletRequest request = rundata.getRequest();
PortalLogger.logDebug(
"BugWatcherPortletContent:: build normal context");
HttpSession session = null;
int bugProfileId = 0;
Hashtable bugProfiles = null;
Hashtable bugData = null;
boolean fetchProfiles = false;
try {
session = request.getSession(true);
// Attempting to get the profiles from the session.
//If the profiles are not present in the session, then they would have to be
// obtained from the database.
bugProfiles = (Hashtable) session.getAttribute("Profiles");
//Getting the selected bug profile id.
String bugProfileIdObj = request.getParameter("bugProfile" + pId);
// Getting the logged in user
String userId = request.getRemoteUser();
if (bugProfiles == null) {
fetchProfiles = true;
if (bugProfileIdObj == null) {
// setting the bugprofile id as -1 indicates "all profiles" is selected
bugProfileIdObj =(String) session.getAttribute("bugProfileId" + pId);
if (bugProfileIdObj == null) {
bugProfileId = -1;
else {
bugProfileId = Integer.parseInt(bugProfileIdObj);
else {
bugProfileId = Integer.parseInt(bugProfileIdObj);
session.setAttribute(
("bugProfileId" + pId),
Integer.toString(bugProfileId));
//fetching the bug list
bugData =BugWatcherAPI.getbugList(userId, bugProfileId, fetchProfiles);
PortalLogger.logDebug("BugWatcherPortletContent:: got bug data");
if (bugData != null) {
Hashtable htProfiles = (Hashtable) bugData.get("Profiles");
} else {
htStore.put("NoProfiles", "Y");
} catch (CodedPortalException e) {
htStore.put("Error", CommonUtil.getErrMessage(e.getMessage()));
PortalLogger.logException
("BugWatcherPortletContent:: CodedPortalException!!",e);
} catch (Exception e) {
PortalLogger.logException(
"BugWatcherPortletContent::Generic Exception!!",e);
htStore.put(     "Error",CommonUtil.getErrMessage(ErrorConstantsI.GET_BUGLIST_FAILED));
if (fetchProfiles) {
bugProfiles = (Hashtable) bugData.get("Profiles");
session.setAttribute("Profiles", bugProfiles);
// putting the stuff in the context
htStore.put("Profiles", bugProfiles);
htStore.put("SelectedProfile", new Integer(bugProfileId));
htStore.put("bugs", (ArrayList) bugData.get("Bugs"));
return htStore;
=============================================================
And I am trying to call this function as it can capable of fetching the data from the database by "getbugProfiles".
In the new class bugWatcherRefreshAction.java I have coded a part of code which actually clears the caching.Below I am giving the required part of the code:
=============================================================
public void doPerform(RunData rundata, Context context,String str) throws Exception {
JetspeedRunData data = (JetspeedRunData) rundata;
HttpServletRequest request = null;
//PortletConfig pc = portlet.getPortletConfig();
//String userId = request.getRemoteUser();
/*String userId = ((JetspeedUser)rundata.getUser()).getUserName();//sraha on 1/4/05
String pId = request.getParameter("PortletId");
PortalLogger.logDebug("just after pId " +pId); */
//Calling the variable holding the value of portlet id from BugWatcherAction.java
//We are getting the portlet id here , through a variable from BugWatcherAction.java
/*BugWatcherPortletContent bgAct = new BugWatcherPortletContent();
String portletID = bgAct.pId1;
PortalLogger.logDebug("got the portlet ID in bugwatcherRefreshAction:---sraha"+portletID);*/
// updating the bug groups
Hashtable result = new Hashtable();
try {
request = data.getRequest();
String userId = ((JetspeedUser)data.getUser()).getUserName();//sraha on 1/4/05
//String pId = (String)request.getParameter("portletId");
//String pId = pc.getPorletId();
PortalLogger.logDebug("just after pId " +pId);
PortalLogger.logDebug("after getting the pId-----sraha");
result =BugWatcherAPI.getbugList(profileId, userId);
PortalLogger.logDebug("select the new bug groups:: select is done ");
context.put("SelectedbugGroups", profileId);
//start clearing the cache
ContentCacheContext cacheContext = getCacheContext(rundata);
PortalLogger.logDebug("listBugWatcher Caching - removing markup content - before removecontent");
// remove the markup content from cache.
PortletContentCache.removeContent(cacheContext);
PortalLogger.logDebug("listBugWatcher Caching-removing markup content - after removecontent");
//remove the backend content from cache
CacheablePortletData pdata =(CacheablePortletData) PortletCache.getCacheable(PortletCacheHelper.getUserHandle(((JetspeedUser)data.getUser()).getUserName()));
PortalLogger.logDebug("listBugWatcher Caching User: " +((JetspeedUser)data.getUser()).getUserName());
PortalLogger.logDebug("listBugWatcher Caching pId: " +pId);
if (pdata != null)
// User's data found in cache!
PortalLogger.logDebug("listBugWatcher Caching -inside pdata!=null");
pdata.removeObject(PortletCacheHelper.getUserPortletHandle(((JetspeedUser)data.getUser()).getUserName(),pId));
PortalLogger.logDebug("listBugWatcher Caching -inside pdata!=null- after removeObject");
PortalLogger.logDebug("listBugWatcher Caching -finish calling the remove content code");
//end clearing the cache
// after clearing the caching calling the data from the database taking a fn from the portletContent.java
PortalLogger.logDebug("after clearing cache---sraha");
BugWatcherPortletContent bugwatchportcont = new BugWatcherPortletContent();
Hashtable httable= new Hashtable();
httable=(Hashtable)bugwatchportcont.loadContent();
PortalLogger.logDebug("after making the type casting-----sraha");
Set storeKeySet = httable.keySet();
Iterator itr = storeKeySet.iterator();
while (itr.hasNext()) {
String paramName = (String) itr.next();
context.put(paramName, httable.get(paramName));
PortalLogger.logDebug("after calling the databs data from hashtable---sraha");
} catch (CodedPortalException e) {
PortalLogger.logException("bugwatcherRefreshAction:: Exception- ",e);
context.put("Error", CommonUtil.getErrMessage(e.getMessage()));
catch (Exception e) {
PortalLogger.logException("bugwatcherRefreshAction:: Exception- ",e);
context.put(     "Error",CommonUtil.getErrMessage(ErrorConstantsI.EXCEPTION_CODE));
try {
((JetspeedRunData) data).setCustomized(null);
if (((JetspeedRunData) data).getCustomized() == null)
ActionLoader.getInstance().exec(data,"controls.EndCustomize");
catch (Exception e)
PortalLogger.logException("bugwatcherRefreshAction", e);
===============================================================
In the bugwatcher Action there is another function called PostLoadContent.java
here though i have found the portlet Id but unable to fetch that in the bugWatcherRefreshAction.java . I am also giving the code of that function under the bugWatcherAction.Java
================================================
// Get the PortletData object from intermediate store.
CacheablePortletData pdata =(CacheablePortletData) PortletCache.getCacheable(PortletCacheHelper.getUserHandle(
//rundata.getRequest().getRemoteUser()));
((JetspeedUser)rundata.getUser()).getUserName()));
pId1 = (String)portlet.getID();
PortalLogger.logDebug("in the bugwatcher action:"+pId1);
try {
Hashtable htStore = null;
// if PortletData is available in store, get current portlet's data from it.
if (pdata != null) {
htStore =(Hashtable) pdata.getObject(     PortletCacheHelper.getUserPortletHandle(
((JetspeedUser)rundata.getUser()).getUserName(),portlet.getID()));
//Loop through the hashtable and put its elements in context
Set storeKeySet = htStore.keySet();
Iterator itr = storeKeySet.iterator();
while (itr.hasNext()) {
String paramName = (String) itr.next();
context.put(paramName, htStore.get(paramName));
bugwatcherRefreshAction bRefAc = new bugwatcherRefreshAction();
bRefAc.doPerform(pdata,context,pId1);
=============================================================
So this is the total scenario for the fetching the data , after clearing the cache and display that in the portal.I am unable to do that.Presently it is still fetching the data from the cache and it is not going to the database.Even the portlet Id is returning as null.
I am unable to implement that thing.
If you have any insight about this thing, that would be great .As it is very urgent a promt response will highly appreciated.Please send me any pointers or any issues for this I am unable to do that.
Please let me know as early as possible.
Thanks and regards,
Santanu Raha.

Have you run it in a debugger? That will show you exactly what is happening and why.
