Access Specifiers for a class

Why we can't declare private or protected for a class as access specifier.
Can you give me an example on it.

This is the third time someone asked something like this today:
http://forum.java.sun.com/thread.jspa?threadID=664848 (where someone references your post on JavaRanch).

Access specifiers for interface methods

When we implement the interface ,we have to specify the implementing method access specifier to be "PUBLIC" ,but not "PROTECTED" or "PRIVATE".
Compiler is giving an error -- attempting to assign weaker access privileges ,when we specify protected.
what is the internal reason for this?Why we shouldnt make the access weaker in the implementing class.
Can any one help me on this.Your help is highly appreciated.

When we implement the interface ,we have to specify
the implementing method access specifier to be
"PUBLIC" ,but not "PROTECTED" or "PRIVATE".
Compiler is giving an error -- attempting to assign
weaker access privileges ,when we specify protected.
what is the internal reason for this?There is absolutely no point in having a private interface method. The interface represents a visible abstraction and private methods are never visible so it is a contradiction in terms.
An interface is intended to represent an abstraction that a user (software) uses. Protected via child/parent represents a usage that is restricted to a child from a parent. The child can already see the parent so there is no point in having an abstraction for the child. And it would probably be unwise to limit a child by such an abstraction.
Protected via the package and interfaces is more contentious as to why it is not allowed. There are those that argue that this should be allowed so that a package can use interfaces but restrict them to the package. To me this seems like a minor point given that most interfaces will probably represent an abstraction to other packages and not within a single package. This applies specifically to default access as well.

Default access specifiers for void main()

I m having one problem that if i make void main(String a[])
syntax like private static void main(String args[]) and run using jdk1.4 it will run. So my question is that why this is possible still i making main() private. If i run it in jdk1.5.0 then it give error main is not public so what was the problem with the jdk1.4?

Congratulations on your first post after almost 2
years. ?The most impressive thing is that he remembered his
password ...I posted by first message in 2004, I only used this account to read the bugdatabase and vote on bugs prior to that. So I don't see anything strange in having an account, and not using the forums.

Ps. But I'm also impressed by the fact that he remembered the password, I had an account which I created in -97, but I forgot the password to that account :(

My java program runs fine even if i don't specify access specifier of class

Hi,
My java program runs fine even if i don't specify access specifier of class as public .
Then why do they say that atleast one class should be specified as public.
please help.

public access specifier is the default access
specifier
so if you dont give the access specifier before the
class name it is not wrong.I think that you are wrong. The default specifier is package or "package-private".
See here:

About access specifiers (inheritance)

abstract Class A
abstract public add();
Class B extends A
protected add() //this wont work
//some code here
The access specifier for add method in A is public ,and in B is protected.This is not allowed by compiler.
Why cant we make the access weaker in the sub class?What is the drawback in allowing to make the access weaker.

Because any class that uses class A has the right to expect to use the add() method, since it is public in A. Since B is an A, it must allow some one to use an instance of B as if it were an A.

Java inner class access specifiers

public class MyClass1 {
public static void main(String argv[]){ }
/*Modifier at XX */ class MyInner {}
What modifiers would be legal at XX in the above code?
1) public
2) private
3) static
4) friend

Iam a newbie to javaI don't care. I still assume you have a brain and expect you to use it.
and iam struck with this
question, iam getting a compile time error for any
access specifiers mentioned as options, but the
answers given by my superior are 1,2,3, are
correct..Then you made a typo or whatever. Make sure you eliminate the problems that are not "illegal access modifier" errors.
What good is knowing the reply to this if you can't even write an example?

Java class specified for a rule not present in the archive path

While checking an implementation of configurator, I found a CX rule that has a java class associated with it oracle.apps.cz.cx.xxx.AVCX
But, when I clicked the 'Choose class' button to check where this class is located, I am unable to find the same in the list of available classes.
I have also checked the jar file containing the custom java classes with no avail.
But, the functionality works fine as expected. i.e., while clicking the UI button that invokes this CX rule, it works as it should.
What could be the reason for this? Could the java class be hidden somewhere else other than the archive path specified for this model?
Thanks in advance for any advise.

Hi Biju,
In this case, this class may be located on the server file system. To know the location of any class on server system, you can do following:
Open http://host:url/OA_HTML/CZInfo.jsp
Enter your classname with path in apprpriate input box and then find it. It would display the location of the class in filesystem from where its loaded.
Thanks,
Pankaj

Unable to locate specified base class 'resources.style1.HelpButtonIcon' for component class

Hi,
I have a Flex (4.1.0) project, which has many skinnable custom components. The application allows a user to choose another style which changes these skins via loading a new compiled CSS. These non-default skins are in a separate Flex project. I've not had a problem with this method until now.
The custom component I am skinning contains several icons which are defined in the component like this:
[SkinPart(required="true", type="mx.core.IVisualElement")]
public var componentIconHelp:IFactory;
then I use the iconRendererFunction to return the appropriate component part:
private function iconRendererFunction(item:Object):IFactory
     //truncated method
     return componentIconHelp;
Within the skin for "style1", I then have
<s:Skin xmlns:fx="http://ns.adobe.com/mxml/2009"
     xmlns:s="library://ns.adobe.com/flex/spark"
     xmlns:mx="library://ns.adobe.com/flex/mx"
     xmlns:style1="resources.style1.*">

<fx:Metadata>
     [HostComponent("myApp.components.ButtonComponent")]
</fx:Metadata>
<fx:Declarations>
     <fx:Component id="componentIconHelp">
          <style1:HelpButtonIcon />
     </fx:Component>
</Declarations>
When I try to compile this, I get the "Unable to locate specified base class 'resources.style1.HelpButtonIcon' for component class 'resources.style1.ButtonComponentSkinInnerClass0'" error.
If I remove the HelpButtonIcon from the <fx:Component> declaration, and just put it in the main body of the skin, it compiles and renders, but I need it to be a component (there's multiple components I have to choose from to display, similar to the ButtonBar skin).
Any ideas why it's not compiling and what I need to do to achive this?
Thanks

Thanks, one step closer (or further away :-)
I tried adding the airspark.swc to the library path for the project and it made no difference so I added:
-external-library-path /Applications/Adobe Flash Builder 4/sdks/4.0.0/frameworks/libs/air/airspark.swc
to the external tools configuration and now get the error:
command line: Error: unable to open 'Flash'
The project itself runs fine, it's only the ASDocs that's causing problems.

No servlet class has been specified for servlet null

Hi,
I�m trying to bend tomcat in my own application. Therefore I�m using the Embedded Tomcat version 5.5.23.
I have started only a server, engine, host and context, so I have a server without the sockets etc. this because it has to become a test-application for the web-app of the company.
The server starts gracefully, but when I call context.invoke(request,response) I get this error:
SEVERE: Allocate exception for servlet null
With this stacktrace:
javax.servlet.ServletException: No servlet class has been specified for servlet null
at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1016)

does anyone has a idea what the cause of this problem is? The request I send is �GET /index.jsp� using a MockHttpServletRequest of the spring framework. I convert the mockhttpservletrequest to a org.apache.cataline.connecor.Request. and that works.
The code in tomcat where the error is caused by:
// Complain if no servlet class has been specified
if (actualClass == null) {
unavailable(null);
throw new ServletException
(sm.getString("standardWrapper.notClass", getName()));
Thanks in advance.

Yes , you are correct. We dont need to replicate DDIC tables for direct BW replication. This was the first time we were working with BW on Hana and never installed DMIS component on that system. The error was gone after we put the addon.

Specifying access rights for page tabs

Hello
I have trouble with specifying access rights for tabs that are inside another tab.
I have a group named "Customers" and a group for each of our customer companies. The company-groups are all members of the Customers group.
Then i created a tab called "Customers" which i specified access rights to the Customers group.
Under the customers tab, i created one tab for each customer and i've specified access rights to each tab.
I want to accomplish that customers who log into the portal only are able to see theyr own tab, but this doesn't seem to work properly.
Have anyone had this problem before?
Regards
Per-Jarle Sfther

Per-Jarle,
Are you sure that the users are not part of a group that is included in the group you gave access to on the tab?

Hi again,
I think I've solved the problem :)
The problem was the version of gcc
I've tried using the gcc shipped with solaris 10 in /usr/sfw
and the problem get solved.

[Fwd: Client accessing MBeanHome for more than one domain receives SecurityException]

Fwd'ing to security newsgroup

Subject: Client accessing MBeanHome for more than one domain receives
SecurityException

Hi,
When a client accesses MBeans of more than one domains (Weblogic 8.1)
that have
different passwords, it receives a SecurityException. This occurs when
the MBeanHome
for each domain is looked up at initialization and reused for each
request ( to
access MBeans ). The security exception does not occur if the MBeanHome
for each
domain is looked up for each request. On initial review, this behavoir
seems inconsistent.
Looking up the MBeanHome for each request may introduce a significant
overhead.
I am not sure if concurrent lookups would also cause the same problem.
I have read on another post that we can work around this problem by
establishing
a trust relationship between the servers, but this may not be feasible
when one
is monitoring a lot of servers and the overhead of configuration may be
an issue.
I have attached code that can reproduce the problem.
Please advise on the correct approach.
Thanks

* Note: the exception is caused only when the MBeanHome for each domain is cached and used for subsequent
* transactions. The exception does not occur if the MBeanHome for each domain is looked up for each transaction. This
* would significant overhead in practice. Also the transactions across the various domains occurs serially, hence
* the effect of concurrent lookups has to be tested.
* Usage:
* This class has been tested with weblogic 8.1
* The class needs weblogic.jar in its classpath
* One can specify the weblogic details as System properties. The properties need to be specified in
* the following format:
* wls.host.n, wls.userId.n, wls.password.n where n is the weblogix instance number. Also specify
* the boolean system property reconnect.each.iteration to toggle between reconnecting or not reconnecting
* for each iteration. When not reconnecting for each iteration, the MBeanHome is reused and the Security Exception
* occurs.
* Following is the example of system properties
* -Dwls.host.0=localhost:7001 -Dwls.userId.0=weblogic -Dwls.password.0=weblogic
* -Dwls.host.1=localhost:7011 -Dwls.userId.1=weblogic -Dwls.password.1=weblogic1
* -Dwls.host.2=localhost:7021 -Dwls.userId.2=weblogic -Dwls.password.2=weblogic2
* -Dreconnect.each.iteration=false

Problem with access specifier and static???

I've a question. I saw a code written for Sun's Java Tutorial. The program had three class methods and all of them start like this:
static public void methodName1{
static public void methodName2{
and
static public void main(String[] args){
My question is why the keyword static was used first? Why not access specifier? I mean what's the reason behind it? Is there any difference between them?
Thanks in advance.
--DM

The order doesn't matter. The programmer thought it was a good idea for some reason. I might be tempted to do it if I had static and instance methods with the same name or something like that.
public static void myMethod() {
public void myMethod() {
or
static public void myMethod() {
public void myMethod() {

Need new access specifier

I think there must be another access specifier that is like protected but not friendly, I mean only the supclasses can access that, not the classes in that package.
Suppose a class that has private or friendly fields and I had to define another field of the same type for its subclass.
Or I have a class with a protected field that I know I will use it if I want to define a subclass of it. But I don't want to let the other classes in thatpackage modify this field unintentionally.
The problem is not only for fields. There are situations that I want to permit subclasses to call a method but I don't want other classes in the same package call it.

there isn't.
perhaps you need to think more about which classes sit in which packages ?
maybe a better package structure would give you this control.

Regarding Protected access specifier

Hi ,
I thought that indeed you could access protected data member from another package IF you are using Inheritance. It makes the data memeber in question "friendly" to the derived class. At least that is my understanding.
You can not access protected data element directly in different packages. package test1;
public class Test123 {
protected int x=42;
package test2;
import test1.Test123;
public class Test234 extends test1.Test123{
     public static void main(String args[]){
          Test123 ob=new Test123();
          System.out.println("x="+ob.x);
but My question is that ..if u run this program its not compile..Compile time exception is throws saying that the field Test123.x is not visible..but according to protected access specifier this will work...and one thing that if i make field ' x ' of Test123 as public it is working... How it is possible ...can anybody pls help it out.. Thanx in advance...

This access is provided even to subclasses that reside in a different package from
the class that owns the protected feature.As you have found this (and similar) can be confusing.
Have a look at the Java Language Specification (http://java.sun.com/docs/books/jls/third_edition/html/names.html#6.6.7) "6.6.7 Example: protected Fields, Methods, and Constructors". Can you see the difference between the delta() and delta3d() methods?
"A protected member or constructor of an object may be accessed from outside the package in which it is declared only by code that is responsible for the implementation of that object." As another example of this, the following compiles OKpackage test2;
import test1.Test123;
public class Test234 extends test1.Test123 {
    public static void main(String args[]) {
        Test234 ob = new Test234();
        System.out.println("x=" + ob.x);
}When run it prints "42" - showing that the same d@mn field is being accessed! Like you, I'd appreciate hearing a simple rationale for this (if there is one).
