How are static methods handled in a multithreaded application?

hi
i have a class Drawer with a static method public static draw(Graphics g). now assume there are more thrads callin at the same time Drawer.draw(g). What happens? have some threads to wait until the others have finished calling the method, or can static methods be multithreaded, (can they perform simultaniously)?
thanks, jo

ups, i am not drawing on the screen, but in every thread i am drawing a Image. this means before i call the static method in every thread there will be created a BufferedImage and then i pass the Graphics from this images to the static method. also in this case the method performs simultaniously? every thread has its own image and graphics, so the static method should be perform at the same time, isn't it?

Are static methods in Java thread safe?

Are static methods in Java thread safe?
thanks,
suresh

if static method use the instance variable
You mean member variable, where member variables are either class variables (static) or instance variables (non-static).
then you have to make it thread safe using
synchronization Not necessarily. Depends on requirements and usage context.
else in case of local var. it
is thread safe. Not necessarily. That local variable could refer to an object that's visible to multiple threads.
Statements like "Local variables are threadsafe but member variables aren't" are an oversimplification.
Something is threadsafe if it cannot be made to behave incorrectly simply by running it in a multithreaded context. Determining that can be very difficult.

Why are static methods called with null references,valid ?

This is my code :
package inheritance;
public class inh6{
     public static void method(){
     System.out.println("Called");
     public static void main(String[] args){
          inh6 t4 = null;
     t4.method();
O/P :
CalledHere t4 is a null reference and yet we are able to call a method on it,why is null pointerexception not thrown.Why are we able to call static methods using null references ?
t4 is null means it doesnot refer to any memeory address,hence how is method() called correctly.
I hope i am clear. :)
Thank you for your consideration.

By memory address i mean the memory location the reference is pointing to.I know what you mean. But if you think it's relevant, can you show me where in the JLS it says anything about memory locations?
>
You can do that because a) t4's type is "reference to inh6" and b) method() is declared static, which means that you don't need an object to call it, just the class. That class comes from the compile time type of t4. The fact that t4 is null at runtime is irrelevant.
So at compile time the type of t4 is inh6 and hence the method is called.Is it ? Had method() not been static a NullPointerException would have been thrown.Correct.
With non-static, non-private, non-final methods, which implementation of the method gets called is determined at runtime, buy the class of the object on which it's being called. If any one of those "non"s goes away, then the method is entirely determined at compile time, and in the case of static methods, there's no instance necessary to call the method in the first place.

Business vs. Private purchase - how are App updates handled?

Hi,
I have my own business, but already purchased a few apps for private use on my Mac. Now I need to make a business purchase and I'm wondering how the App Store handles this.
If I switch accounts, can I still see, run, and update the same apps? Do I need to switch accounts to use an app? Do I (please no) need to log out and in to use an app from a different account?
Any help is appreciated, thanks!
Vincent

You don't need to be logged in with the purchasing account in order to use a app.
You would have to log in with the purchasing account in order to update.

Are Static methods Thread safe?

Hello All
I have a static method that takes a integer and returns a mathematically processed result.
Since this method is frequently required, I have placed it in a common class and declared it as static.
I want to know whether this method is thread safe?

There's nothing special about static methods, with regard to thread safety. If they access shared objects, then such access will usually need to be controlled by synchronisation; this might be on the object being accessed, some higher-level object or a special object allocated purely as a lock. The only way that you might think of them as special is that there's no instance of the Class on which you can synchronise.
You can declare a static method as synchronised. If you do, it will be synchronised on the single Class object of the class in which it is declared. This means that only one thread can be executing any part of the method at any one time. However, I understand that the Java Runtime itself sometimes synchronises on this Class object for its own reasons, therefore you might sometimes find a synchronised static method blocks when no other thread is executing it. Usually better, therefore, to explicitly synchronise on some object or other, than to use synchronised static methods.

How to configure ENV and DB for multithreaded application?

Hi,
From document, I know DB_THREAD must be checked for both ENV and DB, but , I don't know which one is best choice for multithreaded application while facing DB_INIT_LOCK and DB_INIT_CDB. In my application, there maybe multi readers and writers at the same time, should I use DB_INIT_LOCK instead of DB_INIT_CDB? what other flags should I use?
DB_INIT_CDB provides multiple reader/single writer access while DB_INIT_LOCK should be used when multiple processes or threads are going to be reading and writing a Berkeley DB database.
Thanks for your seggestions and answers.

Thanks for the explanation,
The Berkeley DB Concurrent Data Store product
allows for multiple reader/single writer access
to a database. This means that at any point in time,
there may be either multiple readers accessing a
database or a single writer updating the database.
Berkeley DB Concurrent Data Store is intended for
applications that need support for concurrent updates
to a database that is largely used for reading.
If you are looking to support multiple readers and
multiple writers then take a look at the Transactional
Data Store product
(http://download.oracle.com/docs/cd/E17076_02/html/programmer_reference/transapp.html)
In this case the Environment is typically opened with:
DB_INIT_MPOOL, DB_INIT_LOCK, DB_INIT_LOG, and DB_INIT_TXN.
Let me know if I missed any of your question.
Thanks,
Sandra

How are session timeouts handled

Hi,
Can anyone tell me how session timeouts are handled by the Servlet
Engine.
What is the exact role of the SessionInvalidator class. Are sessions
correctly timed
out by iAS, because I get strange behaviour in handling session timeouts
in my application
which is following MVC architecture.
What I am observing is that sessions dont seem to timeout after the
length of
time specified and sometimes they do timeout correctly. The difference
between the
time the session should have timed out and when it actually does is too
high, which is
really a concern for us.
Thanks in advance to evryone.
Amar bhat.

Hi AmarBhat,
Actually this is a bug in iAS (bug id: 556909, Status: Fixed ). This is
happeninig because iAS has a bad ( late) cleanup of timed out sessions. The
getSession method (HttpSession) calls IsRequestedSessionIdValid() as a check
for timeout and this check returns "Valid" even after a couple of seconds of
timeout. Thus, the getSession from Java layer returns the valid session. So
you are still able to read and write data on the session.
We can specify iAS the session to invalidate itself after being timeout.
Alternately, we can do it manually with HttpSession method, invalidate().
Plese get back if you have any issues.
Thanks,
Rakesh.

How are Static File mime types determined?

How does APEX determine the mime type for imported static files?
We have a number of javascript files in our application, some of which are listed on the Static Files page as "text/html" and some are "text/plain". But some are imported as "application/octet-stream" which prevents them from being edited within APEX.
All of these files contain plain text javascript functions.
File sizes range from 539 bytes to 21251 bytes
We tried changing the extensions from ".js" to ".jscript" and reimported them. They were all given a mime type of "text/plain". But one file was misnamed with the extension ".jsript", so we deleted it, changed the extension to ".jscript" and re-imported it. It was imported as "application/octet-stream" even though it was exactly the same file just renamed!
What's going on?

I am trying to use a rather older programming language called Mozart, an extension of OZ. I installed it as a binary, but instead of storing its component binaries in a place like /usr/local/oz/bin/. they are all enclosed inside the /Applications/Mozart.app/Contents/Resources/bin/. which cannot be opened nor can a soft link be made to it located outside the Mozart.app wrapper.
The only alternative is to try to edit the mimeTypes.rdf files, and give it the full path name to the inside of Mozart.app were the program used for web applications is stored. It is stored in ~/Library/Application Support/Mozart/, which can only be accessed in more recent Mac OS X by going to finder and holding the Option key while opening the Go menu; this will make the ~/Library visible and accessible.

JSF security question - how are public methods protected?

I'm somewhat new to JSF, so pardon my ignorance if this is a silly question.
Let's say you have a bean with several public action methods. You create a JSP and specify some of those methods as "actions" or "actionListeners".
How well protected are methods that are not exposed via the JSP? Is there anything stopping people from analyzing the rendered HTML, seing how it binds to a method "${bean.editABC}," and modifying it to the equivalent of "${bean.deleteABC}," for example?
Thank You.

Does they appear in the HTML source anyhow? I've never seen it.

How are valuation types handled in SRM

Hi SRM Gurus,
We have a back end ERP system which uses valuation type in Material accounting view. We are using Extended classic sceanrio and wanted to know if while PO create in SRM, based on the MM master data from ERP, can we have valuation types in SRM PO line items. I saw in BBP_PD transaction for a PO line item, there was a valuation type field BE_VAL_TYPE in table BBP_PDBEI.
Also wanted to know if Vendot and Plant jursidcition entered in MM - when replicated, where do they reside in SRM tables?
Will award points for replies found useful.
Thanks,

Ryan,
We wanted to use valuation types as well. Even though you have the BE_VAL_TYPE field, we didn't want to make a modification to allow the field to show on the screen. So, we created a customer field, appended to the appropriate structures and maintained methods in the BBP_DOC_CHECK_BADI, BBP_DOC_CHANGE_BADI, BBP_CREATE_BE_PO_NEW & BBP_CREATE_BE_RQ_NEW BADIs in order to process the field.
I hope that helps.
Regards, Dean.

How are control characters handled in keyboard layouts?

Warmup question: What exactly is the difference between an "input method" and a "keyboard layout"?
Real question: What exactly happens when I switch keyboard layouts and enter control characters, and how can I change it?
I'll use as an example Hebrew-QWERTY and the "a" key. That key maps to Hebrew character aleph or א. What happens when I press control-a?
The Emacs text editor claims to receive a control-aleph, saying "^א is undefined". This is a very strange character: א with bit 26 set. It doesn't even have a Unicode codepoint.
TextEdit normally responds to control-a by moving to the start of the line. It doesn't do so with Hebrew-QWERTY in force, hence it's not getting a control-a. I have no idea what it is getting.
The goal, by the way, is to create a keyboard layout that does NOT change the mapping of control characters. I don't want control-a to send a useless control-aleph; I want it to send control-a as usual. But if I examine the Hebrew-QWERTY layout in (say) Ukelele, it knows nothing of control-aleph and claims to map control-a to itself as usual. Therefore something else is producing these weird control characters. Who?
If I'm hopelessly confused, please don't hesitate to say so. I wouldn't be surprised to learn that I'm missing something simple but crucial.

Regarding control characters, you might try posting a query on the Ukelele page -- the fellow who makes that app knows a lot about how all this works.

How are tax updates handled in SAP for asset depreciation?

We are implementing Assets and currently using a system that not only calculates the tax on depreciation but also updates any new changes to the taxes as mandated by the federal and state government.
My understanding is that SAP does not auto update the tax changes in the system unless we have a tax software, is that right? And if we have no need for a tax software just to update depreciation tax changes, what are the options out there that will enable the new tax to be calculated and applied in SAP?
We are looking for an auto option instead of manually updating the percentage rates/tax for calculating depreciation in SAP. Is there any software that can be interfaced to SAP that can perform this function and enable the calculation of depreciation tax?
Appreciate any input/suggestions or help in resolving this issue.
Thanks

In AM you set-up a separate depreciation are for TAX with complete different rules as your normal depreciation. You can do with it what you want to get the correct values.
Based on your tax requirements you can set this up. If there is a specific question you can drop it on this forum:
You have option like revaluation, inflation, unplanned depreciation, write up...... When you have activated the extension AE-FIN you have some extra options.
There is not a standard for tax changes. You have to know the change and based on that to use the correct option to update the values. There are hundreds of possible changes.

How are duplicate parameters handled when starting WLS?

This puzzles me because it looks like that was the original heap size. I am wondering if it is because the parameter appears twice.
So my question is, "If a parameter is used twice, is the first one used? the last one? or is it an error?"
Now to see if I can add an image. Guess not. Soooo... note -Xms=512m appears twice.

I just noticed that in one place it is -Xms=512m and in the other it is -Xms512m. But the example I was given works - but apparently with JRocket, not sun. Does the format of this parameter vary between Hotspot and JRocket??? But the question on duplicate parameters remains.

Advantages and disadvanteges with static methods

Hi,
Can anybody suggest me the advantages and disadvantages of static methods? In my project i am using templates which are used by different programs and in that templates i am using static methods.
It is web application. is there any problems if made methods as static in templates that are used by diferent clients?
Thanks
Karimulla

A static method can't be overridden, and static methods are usually only used for some utility methods and other things which don't belong to the class. I would probably not make the methods static.
