SelectNodes method in XMLNode class...

Can anyone provide me a small code that shows how to use the
selectNodes method in the XMLNode class? I don't know how to
define the NSResolver that should be pass as an argument to this
method.
Thanks,

The selectNodes function is used in XMLElement and XMLDocument
nodes. This function is used to extract contents from the
tree/subtree based on the select patterns allowed by XSL.
The second parameter of selectNodes, is used to resolve namespace
prefixes (give the expanded namespace URL given a prefix).
XMLElement implements NSResolver, so it can be sent as the
second parameter. XMLElement resolves the prefixes based on the
input document. You can implement the NSReolver interface, if
you need to overide the namespace definitions.
The sample code to use selectNodes
public class SelectNodesTest {
public static void main(String[] args) throws Exception {
String pattern = "/family/member/text()";
String file = args[0];
if (args.length == 2)
pattern = args[1];
DOMParser dp = new DOMParser();
dp.parse(createURL(file)); // Include createURL from
DOMSample
XMLDocument xd = dp.getDocument();
XMLElement e = (XMLElement) xd.getDocumentElement();
NodeList nl = e.selectNodes(pattern, e);
for (int i = 0; i < nl.getLength(); i++) {
System.out.println(nl.item(i).getNodeValue());

Problem using XMLNode class with schema registered XML

Hello,
I'm working on an XML document management system that currently uses CLOB storage of XML data. I'm trying to switch over to a schema registered/object-relational approach to increase performance.
However, the code (which I didn't write) uses the XMLNode class and its methods such as selectSingleNode which work when used against unregisterd xml, but breaks when used against registered xml. I don't know if this is a namespace issue or what.
Here's a sample.
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true); // don't know if this is neccessary
newICD = (XMLDocument) dbf.newDocumentBuilder().parse(icdFile);
docNode = (XMLNode) newICD.getDocumentElement();
//this works with CLOB storage, but returns null with registered schema/O-R storage
tempNode = docNode.selectSingleNode("/sw_icd/TITLEPAGE/DocNum");
Any ideas would be greatly appreciated.
Thanks

When will the setNodeValue() method of XMLNode be implemented?

It seems the setNodeValue() method along with all the other methods of XMLNode are not implemented yet. When will it be available? Also what can I do if I want to build an XMLDocument in Java (but not using Java classes)? Does creating indivdual nodes and later append them together work?
Thanks.

For example, the following code
XMLElement element = new XMLElement("A");
element.setNodeValue("abc");
will cause the following exception:
oracle.xml.parser.v2.XMLDOMException: Node cannot be modified.
void oracle.xml.parser.v2.XMLNode.setNodeValue(java.lang.String)
Why is this? And how to get around it? Basically all I want to do is creating a valid XML by creating individual elements first and then use appendChild() operation to put them together in a hierarchy... can this work?
Thanks!

Returning a HashMap K, M from a method of a class typed M

So, this is what I have. I have a class parameterized for a bean type of a collection it receives, and in a method of the class, I need (would like) to return a HashMap typed as <K, M> as in:
public class MyClass<M> {
private Collection<M> beanList;
public HashMap<K, M> getMap( /* what do I do here */ );
}I tried to cheat from looking at the Collections.sort method, knowing it uses the List type in its return type as in:
public static <T extends Comparable<? super T>> void sort(List<T> list)So, I am trying:
public HashMap<K, M> getMap(Class<K> keyType)But, it is telling me I need to create class K.
So... how does the Collections.sort method get away with it and I can't????
I suppose I could write the method as:
public HashMap<Object, M> getMap()but became somewhat challenged by my first guess.
Any ideas... or just go with the HashMap with the untyped key?

ejp wrote:
provided K is inferable from the arguments.Or from the assignment context:
Set<String> empty = Collections.emptySet();
Otherwise you have to parameterise the class on <K, M>.You may also specifically provide K when you use the method if the context doesn't give the compiler enough information or if you want to override it.
Example:
Set<Object> singleton1 = Collections.singleton("Hello"); //error
Set<Object> singleton2 = Collections.<Object>singleton("Hello"); //fineEdited by: endasil on 14-May-2010 4:13 PM

Function Module to open a new session displaying a method of a class

Hello All,
I have a method A of class B.
Now, in my current session, I have a button. When the user clicks on this button, what I expect is that a new session be opened and in the new session method A of class B be displayed.
This is similar to the debugger, wherein, in the debugging mode, we can bring up the context menu in the Source Code (Edit Control) tool, and then select "Go To Source Code".
So basically, I am looking for a Function Module which does the same.
I came across Function Module CC_CALL_TRANSACTION_NEW_TASK, however, this will only create a new session.
I could specify the transaction as SE24, but it then opens a new session with this transaction. That is it.
My objective is to display the method of a class in a new session.
Is there any Function Module in this case?
Regards,
Mithun

Hello Sandra,
Thank you very much. That was exactly what I was looking for.
However, instead of calling EDITOR_PROGRAM directly, what I instea did was the following:
1) Created a RFC enabled Function module.
2) Inside this function module, I wrote the following code:
SUBMIT tpda_editor_start AND RETURN
   WITH prgm = is_alert_det-program_name
   WITH incl = is_alert_det-include_name
   WITH dynp = space
   WITH line = is_alert_det-line_no.
The parameters above were similar to the one proposed by you.
Borrowed the above from the class CL_TPDA_SERVICES_TOOLS, method NAVIGATE_TO_SOURCE.
The above is basically called in the debugger, when we use the context menu in the editor tool and invoke the "Goto Source Code" functionality. This eventually calls the EDITOR_PROGRAM FM.
The reason why I did this is because when I was testing the FM, it did not allow me to specify the include as CL_TEST=====CM01. I do not know why, probably I was doing it wrong. But it gave me a message saying that the object does not exist in table TADIR.
Anyway, I did the above steps and it worked exactly as I wanted it to.
I would like to thank you again.
Best Regards,
Mithun
P.S. Forgot to add, I called the above RFC enabled FM as a new task.

"Open method of Workbooks class failed" when opening Excel file via Internet Explorer

(apologies, I posted this first to the general Office 2010 forum, but then realized this was probably a better spot to post)
We have an Excel COM add-in installed on users' PCs. This add-in responds to workbook open events by opening a particular XLA file (also deployed to the PC) to make certain features available. This process works flawlessly when Excel files are
opened locally - but when a user attempts to open an Excel file from an IE link, we get the following error: "Open method of Workbooks class failed". This is happening on the line that is trying to open the XLA file. This only happens
when launching an Excel link from IE - works fine in Chrome or Firefox.
I have found several posts on this topic, but no solutions:
1. This post (https://social.msdn.microsoft.com/forums/office/en-US/73c96005-84af-4648-b103-32b677205be3/open-method-of-workbooks-class-failed)
is the closest to our problem. In this case, the "answer" was that the user may not have access to the 2nd workbook being opened. But in our case, we're opening an XLA that is on the local machine, and I've confirmed that it is not
corrupt and accessible (read & write, just in case!) to Everyone.
2. This (very old) post (http://www.pcreview.co.uk/forums/open-method-workbooks-fails-excel-hosted-ie-t965608.html)
seems similar, but is talking about opening Excel inside of IE. This is not what we're doing - the link is supposed to (and does) open Excel outside of IE. Interestingly, Excel.exe is being launched with the "-embedded" flag, even
though it isn't running in the IE window. When launching Excel by opening the file locally, Excel.exe is run with the "/dde" flag instead. Clearly the "-embedded" mode is what is causing the problem. I could change the
links on the web page to use some JavaScript to open Excel differently... unfortunately, the links are actually generated by SharePoint (the Excel files are in a SP repository), so this is not really an option.
3. This Microsoft KB article (http://support.microsoft.com/kb/268016) talks about problems opening an XLA directly from IE... but this is the case of a link pointing
directly to an XLA file, not opening a regular workbook that in turn opens an XLA, as is my case. In fact, this article specifically points out in the "More Information" section that "End users do not normally open XLAs; instead they open
an XLS that (if needed) loads one or more XLAs during startup." ==> precisely what I'm trying to do that is giving me the error!
I've replicated the situation with a very simple COM add-in (created in VS2010 using VB.Net) and a very simple XLA file (does nothing, just pops up a message in auto_open). For anyone wanting to try it out, here is the exact test case:
1. In Excel, create a simple XLA file containing only the following code, and save it in C:\TEMP\dummy.xla:
Sub Auto_Open()
MsgBox "Auto Open fired"
End Sub
2. In Visual Studio, create a new Excel 2010 Add-In. I created mine via Visual Basic, but I doubt the choice of language matters. Place the following code in ThisAddin.vb:
Public Class ThisAddIn
Private Sub ThisAddIn_Startup(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Startup
AddHandler Me.Application.WorkbookOpen, AddressOf Application_WorkbookOpen
End Sub
Private Sub ThisAddIn_Shutdown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shutdown
End Sub
Sub Application_WorkbookOpen(ByVal workbook As Excel.Workbook)
On Error GoTo ErrHandler
If (Not workbook.Name.Contains("dummy.xla")) Then
MsgBox("Workbook open")
Application.Workbooks.Open("C:\temp\dummy.xla")
Application.Workbooks("dummy.xla").RunAutoMacros(Excel.XlRunAutoMacro.xlAutoOpen)
End If
Exit Sub
ErrHandler:
MsgBox(Err.Description)
End Sub
End Class
3. Build & publish this add-in and install it on the same machine as the XLA created in step 1.
4. Create and save an empty Excel workbook (I called mine WayneTest1.xlsx) - save it locally (on your desktop), and put a copy somewhere on your web server (I put mine directly in c:\inetpub).
5. Create an HTML file with a link to that workbook, saving it to the same web server location - here is mine:
<html>
<body>
<a href="WayneTest1.xlsx">Link to Excel file</a>
</body>
</html>
6. Double click the workbook on your desktop (from step 4) - opens fine, I get the "workbook open" message, following by the "Auto Open fired" message.
7. In Internet Explorer, navigate to the HTML file specified in step 5 and click on the link - when prompted, select "Open" - I get the "workbook open" message, following by the error message "Open method of Workbooks class failed".
Here are a few things I've ruled out / tried so far:
- Unchecked all the "Protected View" settings in Excel, made no difference
- Unchecked all the "File block settings" in Excel, made no difference
- Made sure dummy.xla was open for read & write to Everyone
- Made sure the web page was in Trusted sites and set the security level to Low for those sites in IE
- Tried making the local desktop file (step 6) readonly, made no difference (i.e. launching it locally still worked fine)
- Tried using Excel 2013 - made no difference
Any ideas / suggestions?

Hello Wayne,
Apologies for the delay.
I went through your post and tried to reproduce the issue. I was able to reproduce it. Based
on its complexity and as it requires more in-depth analysis, your question falls into the paid support category which requires a more in-depth level of support.
Please visit the below link to see the various paid support options that are
available to better meet your needs. http://support.microsoft.com/default.aspx?id=fh;en-us;offerprophone

How to call a static method in a class if I have just the object?

Hello. I have an abstract class A where I have a static method blah(). I have 2 classes that extend class A called B and C. In both classes I override method blah(). I have an array with objects of type B and C.
For every instance object of the array, I'm trying to call the static method in the corresponding class. For objects of type B I want to call blah() method in B class and for objects of type C I want to call blah() method in C class. I know it's possible to call a static method with the name of the object, too, but for some reason (?) it calls blah() method in class A if I try this.
So my question is: how do I code this? I guess I need to cast to the class name and then call the method with the class name, but I couldn't do it. I tried to use getClass() method to get the class name and it works, but I didn't know what to do from here...
So any help would be appreciated. Thank you.

As somebody already said, to get the behavior you
want, make the methods non-static.You all asked me why I need that method to be
static... I'm not surprised to hear this question
because I asked all my friends before posting here,
and all of them asked me this... It's because some
complicated reasons, I doubt it.
the application I'm writing is
quite big...Irrelevant.
Umm... So what you're saying is there is no way to do
this with that method being static? The behavior you describe cannot be obtained with only static methods in Java. You'd have to explicitly determine the class and then explicitly call the correct class' method.

Error in using method get_event of class cl_htmlb_manager.

Hi All,
i am trying to get the event details in a particular method as follows;
data: event type ref to cl_htmlb_event .
event = cl_htmlb_manager=>get_event( runtime-> server- >request ).
i am getting an error
field RUNTIME is unknown , it is neither in one of the specified tables nor defined by DATA statement. DATA statement. DATA statement.
Where am i going wrong?
plz help.
BR,
Annu.

Hi Jorge,
I am trying to use it in the method GET_LIST of class CL_SUS_M_ORDER_LIST .
If i use
event = cl_htmlb_manager=>get_event_ex( request ).
again i get the error Field REQUEST is unknown .
and if i dont declare event using data statement
data: event type ref to cl_htmlb_event .
then i get the error that Field EVENT is unknown.
My application is MVC pattern.
So is there anyother way of geting the EVENT details when RUNTIME / REQUEST are not available ?
Thaknks for the reply.

Moving a method from one class to another issues

Hi, im new. Let me explain what i am trying to achieve. I am basically trying to move a method from one class to another in order to refactor the code. However every time i do, the program stops working and i am struggling. I have literally tried 30 times these last two days. Can some one help please? If shown once i should be ok, i pick up quickly.
Help would seriously be appreciated.
Class trying to move from, given that this is an extraction:

So there are peers you can ask, if not your professor. There are certainly also some who actualy know some programming and would teach you if you just asked them.
im a first year student bear in mind though lol!!! and ma struggling, I see that, and the way you handle your problems, that won't change for the next few years.
i may not be as good at java as you, but i can do other things better than you can, and thats life, we all have to start somewhereWhat you also can't do as well as I do is "realizing that using an internet forum is one of the worse ways to have people helping you to learn programming". You're lacking a lot of understanding for concepts where the label "basic" is almost exaggerating. I'm sure you can get that understanding, but being spoon-fed through a forum with no visible effort to figure things out is not the way to do it.

This is what my exact problem.
i've created a bean (DataBean) to access the database. i'm having a servlet program (ShopBook). now to check some details over there in the database from the servlet i'm in need to use a method in the DataBean.
both ShopBook.java and DataBean.java lies in the package shoppack.
in ShopBook i tried to instantiate the object to DataBean as
DataBean db = new DataBean();
it shows the compiler error, unable to resolve symbol DataBean.
note:
first i compiled DataBean.java, it got compiled perfectly and the class file resides inside the shoppack.
when i'm trying to compile the ShopBook its telling this error.
hope i'm clear in explaining my problem. can u please help me?
thank u in advance.

Calling a method from another class... that requires variables?

I'm calling a method from another class to change the date (its a date object) in another class.
I keep getting the error 'setDate(int,int,int) in Date cannot be applied to ()'
My code is:
public int changeDate()
cycleDate.setDate();
}I'm guessing I need to pass 3 parameters (day, month, year), but I'm not sure how! I have tried, but then I get errors such as ')' expected?
Any ideas! :D

but I'm not sure how!
setDate(16, 6, 2008);
I have tried, but then I get errors such as ')' expected?
Any ideas! :Dyou need to post your code if you're getting specific errors like that.
but typically ')' expected means just that, you have too many or not enough parenthesis (or in the wrong place, etc.)
i.e. syntax error

Calling a method from abstarct class

Hi Experts,
Am working on ABAP Objects.
I have created an Abstract class - with method m1.
I have implemented m1.
As we can not instantiate an abstract class, i tried to call the method m1 directly with class name.
But it it giving error.
Please find the code below.
CLASS c1 DEFINITION ABSTRACT.
PUBLIC SECTION.
    DATA: v1 TYPE i.
    METHODS: m1.
ENDCLASS.                    "c1 DEFINITION
CLASS c1 IMPLEMENTATION.
METHOD m1.
    WRITE: 'You called method m1 in class c1'.
ENDMETHOD. "m1
ENDCLASS.                    "c1 IMPLEMENTATION
CALL METHOD c1=>m1.
Please tell me what is wrong and how to solve this problem.
Thanks in Advance.

Micky is right, abstract means not to be instantiated. It is just a "template" which you can use for all subsequent classes. I.e you have general abstract class vehicle . For all vehicles you will have the same attributes like speed , engine type , strearing , gears etc and methods like start , move etc.
In all subsequent classes (which inherit from vehicle) you will have more specific attributes for each. But all of these classes have some common things (like the ones mentioned above), so they use abstract class to define these things for all of them.
Moreover there is no sense in creating instance (real object) of class vehicle . What kind of physical object would vehicle be? there is no such object in real world, right? For this we need to be more precise, so we create classes which use this "plan" for real vehicles. So the abstract class here is only to have this common properties and behaviour defined in one place for all objects which will have these. Abstract object however cannot be created per se. You can only create objects which are lower in hierarchy (which are specific like car , ship, bike etc).
Hope this claryfies what we need abstract classes for.
