I don't know if I understand your question, but you cannot find the class name because it is in run time just an object. You can, however, check if it is an instanceof.
if (genericType instanceof MyType) {
     doMyThing();
}

How to get Class Name given along with java.exe

Hi friends,
I am Mukesh, currently facing one problem
On command prompt to execute any java program we give :
C : \.-- > java ClassName
This ClassName I need in my application, I want to do some post processing on that.
Actually see what I want :
public class Base
static Base object;
public static void main(String[] args) throws Exception
object=(Base)Class.forName("Derived Class Name").newInstance();
void main()
public class Derived extends Base
void main()
System.out.println("Hello World");
I am trying to Run Derived Class, since there is no entry point found, default JVM invoke the Base class's entry point, there I want to load
Derived Class, but I am not getting any identity of derived class in Base class.
I found one temporary solution to this problem :
C: \ -- >java Derived Derived
& in Base class, I have loaded class
object=Class.forName(args[0]).newInstance();
But I dont want to write the same thing twise just to know the Class name which is given along with java.exe.
Is there any way to get the ClassName supplied with java.exe
I have tried a lot, still I am trying !!!
If any one knows the answer, help me.
Regards.
Mukesh.

How to get class name and method name within a class method?

Hi,
In a java class, is it possible to get its class name and the class method?
Please advise.
Thank you.

I mean whether there's any built-in command that will
return the class name instead of code it ourself, for
easier maintenance.
Possible?
this.getClass().getName();

Listing classes name in known package

Hello!
Can you tell me how to get classes name in a package.
String package = "bla.bla.bla";
And the output is like this
Classes in bla.bla.bla :
- ClassA
- ClassB
- ClassCThank's

That misses any classes in a jar file.forgot about archived.. yeah..that would fail.
you can list files in a directory as shown inreply #1, but not in a java package,
since its contents can be distributed what do you mean? when you compile..the compiler
create a dicrectory structor of the package. the
java.class is a file..so you can list it. (I'm not
sure by what you mean distributed)..if you mean
RMI..then yeah..i missed that point too.not only that
it's common to have many source directories :
/Project
    /src
        /api
           /com/mycompany/myprogram
        /test
           /com/mycompany/myprogram
        /impl
           /com/mycompany/myprogramis something I do a lot
>
I guess you have to use reflection for that..even
with reflection..i don't think you can get all the
class name for RMI application (or those
server-client) application.

How can i get all java class names from a package using reflection?

hi,
can i get all classes name from a package using reflection or any other way?
If possible plz give the code with example.

You can't, because the package doesn't have to be on the local machine. It could be ANYWHERE.
For example, via a URLClassLoader (ie from the internet) I could load a class called:
com.paperstack.NobodyExpectsTheSpanishInquisitionI haven't written it yet. But I might tomorrow. How are you going to determine if that class is in the package?
This subject comes up a lot. If you want to do something a bit like what you're asking for (but not quite) there are plenty of threads on the subject. Use google and/or the forum search facility to find them.
But the answer to your question, as you asked it, is "you can't do that".

How to create object by getting class name as input

hi
i need to create object for the existing classes by getting class name as input from the user at run time.
how can i do it.
for exapmle ExpnEvaluation is a class, i will get this class name as input and store it in a string
String classname = "ExpnEvaluation";
now how can i create object for the class ExpnEvaluation by using the string classname in which the class name is storted
Thanks in advance

i think we have to cast it, can u help me how to cast
the obj to the classname that i get as inputThat's exactly the point why you shouldn't be doing this. You can't have a dynamic cast at compile time already. It doesn't make sense. Which is also the reason why class.forName().newInstance() is a very nice but also often very useless tool, unless the classes loaded all share a mutual interface.

How To Get Attribute Names for a Particular VO

Hi ,
How To Get Attribute Names Of a Vo where I can Set Viewattributname To the Table RN Columns Where I am Adding Extra Columns Based on Some Condn..
So wen i am creating new Column to existing Table RN and we Need to add Attribute Name Also...Rt..
And How To get RelationShip Between Database Column Name and Java Vo Attribute Name
Ex: PlanId is the Java VO Attribute Name for the Database Column PLAN_ID
In The Same way Hw We Get the Relation ship for All other columns In the Controller Cllass ..
Can Any One Reply as It is urgent Req...
Thanks ,,
Jithen

Instead of using the VO attribute names to set and get values, best to go to the VO definition, click on Java, and generate the View Row Class with the accessors.
In the class where you're trying to set attributes, instead of a Row class, use the View Row class of your VO (eg ViewObjectName's class would be ViewObjectNameRowImpl), and when retrieving a row from the VO, cast the row to the previously mentioned View Row Class.
At that point you can use the View Row Class's methods that would perform sets and gets of each column.
To get attribute names, I don't know off the top of my head, but there might be a method mentioned in the Javadoc for the ViewRowImpl or ViewObject or ViewObjectDefinition classes to get the attribute/column mapping, or perhaps you can somehow read the XML definition of the VO which has that mapping.
Assuming business components were built automatically and no attribute names were overridden, intuitively the attribute name is a camelcase version of the column name, removing understores and capitalizing the character following the removed underscore - but that's not a fool proof approach. Just a general observation.
Hope this helps.

How to get the name of the current tab.

Hi Experts,
I have two tabs in my tab strip and a button common to both the tabs.Can you please let me know how to get the name of the current tab in the event method of the push button.
Thanks in advance.
Regards,
Arun

1.Declare an Action for OnSelect event of Tabstrip. This event is triggered whenever any change in tab occurs.
2. Declare an Import Parameter in this method
   Tab type String.
3. This parameter has value of the selected TAB.
4. You can set this value in some Attribute in Attribute Tab in this event only (OnSelect):
     wd_this->Att = Tab.
Att is the attribute created by you in Attributes Tab of View. ( of type String)
5. Now the selected Tab ID is stored in this Attribute Att.
6. In the Onaction of Button , retrieve the selected tab value from this attribute using :
           Data : lv type string.
            lv = wd_this->Att
Now lv has your selected TAB ID.
I hope it would help you.

How to get list name through javascript?

Hi,
I wrote javascript for getting list items but here I'm hard coded list name as "Projects"(my list name). How can I get list name automatically with out hard coding,
Appreciate if anyone help.
Thank you.
function DoLogicalDelete()
var clientContext = null;
var oList = null;
var oListItem = null;
// var lstItmIsDeleted = null;
var itmID = getQuerystring('ID');
clientContext = SP.ClientContext.get_current();
oList = clientContext.get_web().get_lists().getByTitle('Projects');
// var oListItemID = SP.ListOperation.Selection.getSelectedItems(clientContext);
oListItem = oList.getItemById(itmID); // getting ID
clientContext.load(oListItem,"Title", "IsDeleted"); // load items to oListItem
oListItem.set_item('IsDeleted', true);
oListItem.update();
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded),Function.createDelegate(this, this.onQueryFailed));

Not sure on which context you are executing the code. If you executing this from the list form and trying to get the current list, then you may need to get the list name from the breadcrumb/list title field. Refer to the following posts for more information
