Get all JNDI names - EJBLocalHome

Hello,
I've tried to get all JNDI names that are deployed on the J2EE Server RI Version 1.3.1. It worked fine with the JNDI names of the EJBs with Remote Client view (EJBHome), but did not work with EJBs with local Client View (EJBLocalHome).
Does anyone knows how could work? Or wether it isn't possible.
Thanks
Here's my code:
InitialContext ct = new InitialContext();
NamingEnumeration bindings = ct.listBindings("");
while (bindings.hasMore() ) {
Binding b = (Binding) bindings.next() ;
Object object = b.getObject();
if(object instanceof Context) {
Context aCon = (Context)object;
NamingEnumeration n = aCon.listBindings("");
while (n.hasMore()) {
Binding b2 = (Binding) n.next() ;
if (b2.getClassName().equals("javax.naming.Reference")) {
Object objRef = ct.lookup("ejb/"+ b2.getName());
if (objRef instanceof EJBLocalHome) {
     System.out.println("localHome");
//here I want to access the EJBLocalHome Interface
     else if (objRef instanceof EJBHome) {
     System.out.println("Home");
     else                              System.out.println("nothing");

I use the listBindings() method in order to get all References to a JNDI name. I do not know how to get all JNDI names that are local. How can I check them?

How to get the JNDI name of an EJB from within itself

Hello,
I'm trying to find a way to get the JNDI name of a session bean from
within itself.
In the application I'm working on we need to support multiple
customers. In order to do that, each EJB has a normal home and remote
interface, a base class bean implementation and different children
bean implemetations for each customer (when the logic for the
customers is different). JNDI is used to get the proper implementation
based on the customer.
I've got an EJB that provides some services that are the same for all
customers, except for the fact that it contains one variable that
should have a different value depending on the customer. I don't want
to creat subclasses just for that. What I want is to be able to get
the JNDI name and set the variable based on the it.
Is there a way to get the JNDI name for the EJB from within itself?
TIA
MJ

How to get all property names and values of an bean instance at runtime?

How can I get all property names and values of an bean instance at runtime?
(The class of the bean instance is dynamic and I can not know before I write the code .)

Look at Class. It has a way to get at all public methods and attributes.
If you need to get to private attributes you can do what the Introspector does and expect the methods to follow the Bean pattern and pull the attributes out based upon that. Privates are all hidden from direct access but through the Bean Pattern they can be figured out.

How get all table name from database

hi master
sir
how get all table name from database

The big question is 'why'.
Selecting from view 'dba_tables' will indeed give the list of all tables in the database, but that includes the dictionary tables and the internal tables, and many others that are probably not of interet to a person who needs to ask this question. Besides, the dba_tables view requires access to a DBA account.
There are several other views: "user_tables" will list all the tables in this user's schema; and "all_tables" will list all the tables this user can access in some way.
The above do not, of course, include any information about synonyms, sequences, views, indexes and so on.
The correct answer and the meaningful answer may be two different things.

Get All instance names in the stage

hi,
is there any way to get all instance name of the objects presents on the stage ? trace them for example
thank you

thank you, it's the correct answer but i still can't solve my problem ,
the thing is that am using a code from http://www.freeactionscript.com that make enemie follow the player, but i need to do some modification, i need to detect collision between enemies so they will not get the one into the other and the thing that i cannot found their instance name, even when i used your function i only get "player_mc : _level0.player_mc" at the output,
here is the code, i will be really greatful if you can find a way to help me solve this problem .
ps :
am trying to write my own code that make enemie follow the player, coz this one looks very complicated

How to get all parameter names along with their values in stored procedure which is being executed

Im using sql server 2012, is there any possible way to get all the parameters of a stored procedure along with the values passed to it.
I need these things to build a xml. I mean this should happen in the procedure which being executed and it should be common for all the procedures.
For example, let us suppose we have to procedures,
uspSave, @name='test' @age=20
uspDelete @id=2
now in uspSave procedure, i need to get @name, @age and the values 'test', 20 and in uspDelete, i should get @id with value 2.
For getting the column names, i tried this,
select parameter_name from information_schema.PARAMETERS where specific_name=OBJECT_NAME(@@procid)
now is it possible to loop through the result of above query and can we get the values.

I think you need running SQL Server Profiler to capture this info even in SQL Server 2012.

Hi,
You can use the for run time type descriptor classes to do this :
Here is a simple example :
REPORT z_assign_comp.
TYPE-POOLS : slis.
include <icon>.

        col3 TYPE i,
      END OF line.
FIELD-SYMBOLS : <fs> TYPE ANY.
FIELD-SYMBOLS : <itab_line> TYPE ANY.
DATA : BEGIN OF t_comp OCCURS 0,
        comp(5) TYPE c,
       END OF t_comp.
DATA : l_struc TYPE REF TO cl_abap_structdescr.
DATA : l_typedesc TYPE REF TO cl_abap_typedescr.
DATA : lt_comp TYPE abap_compdescr_tab,
       w_comp LIKE LINE OF lt_comp.
line-col1 = 11.line-col2 = 'SAP'.line-col3 = 33.
APPEND line.
line-col1 = 44.line-col2 = 'P.I.'.line-col3 = 66.
APPEND line.
ASSIGN line TO <itab_line>.

    p_data      = <itab_line>
RECEIVING
    p_descr_ref = l_typedesc.
"The method returns a reference of a type descriptor class therefore we
"need to Cast the type descriptor to a more specific class i.e

How to get all step names within a group or a sequence?

Hi,
I'd like to show all the names of the steps within a sequence or a group.
I wonder if there is a simple function which can be used directly, such as RunState.PreviousStep.Name.
I tried via a foolish way to append each step name, though it shows all the step names but I still think there is a simple function can access all the step names.
Can anyone give me some suggestion, thanks a lot!!!
Solved!

I've doctored up your sequence a little. But yes you have to loop.
Also, what format do you want the names in?

Get all file names in a folder, set each as text variable

First off, I do not know if this is possible.
For an app I'm writing, I need it to get a list of all the file names inside of a folder, then set a text variable for each of the file names. The app will then display a list of those items, which I know what to do from there.
If anyone knows how I would be able to do this, or alternatives, I would be extremely grateful.
Thanks in advance!

just use any colon separated path (i.e., the desktop would be {color:blue}HD:Users:yourname:Desktop:{colors}) basically, path specifiers come in a number of types:
# text designations - HD:Users:yourname:Desktop (just a normal text line)
# posix designations - /Users/yourname/Desktop (how unix expects paths to be written)
# alias designations - alias "HD:Users:yourname:Desktop" (a pointer to an actual, existing file system element
# file system referents - file "HD:Users:yourname:Desktop:somefile", folder "HD:Users:yourname:Desktop", etc -
# file system objects - Folder "Desktop" of folder "yourname" of folder "Users" of disk "HD"
each has its advantages and disadvantages, and you can coerce between them (though not completely - you need to convert #5 to text before you can convert it to #3, for instance.

Getting jms queue jndi name via jmx

Hi all,
I'm writing a utility that will help us migrate jms messages to new servers, stores, etc. I would like to connect to a server and programmatically discover the jndi names of all the queues and topics on that server. I know how to get all the destination mbeans via jmx, but I don't see a way to get the jndi names for them. They have a Name attr, but it's not the jndi name. Is this possible with WLS 9.2?
thanks

I believe the attribute on the Destination Bean would be JNDIName, but I would use WLST to browse the information available via JMX. I.e.
1) connect to the domain
2) cd into the approriate jms system resource. Then perform ls() and cd() until you find the right information.
3) Then use print cmo - this will give you the JMX object name. ls() will show you the attribute name.
4) So you can either look up the MBeans directly using JMX or walk down the domain hierarchy

Getting jndi name for jms queue via jmx?

All,
I'm trying to write a utility that will do a 9.2-style message export against 8.1 I think I have it all figured out except that I don't know how to get the jndi name of a queue or topic via jmx. I'm using jmx to find queues and subscriptions that have messages waiting, then trying to connect to them to siphon off the messages. I can't just browse jndi for any queue I find because I also want to access the durable subscriptions, for which I need the client and subscriptions ids. Is there a way to map from the jms destination runtime mbean to the jndi name? The getDestination() method isn't supported (throws an exception.)
thanks

Hi John,
You can get destination JNDI names by looking up their value in the JMX configuration mbeans rather than the runtime mbeans. The client-id and subscription-name are available on the JMSDurableSubscriberRuntime mbean.

Tom
