JDeveloper 10.1.2.0.0 - Inner class cannot be found

Hi! 
 
I use Apache MyFaces 1.1.1 (Nightly Build 20051130) to create a Web app and imported all necessary libraries. I want to write a custom ViewHandler at the moment and experience a strange problem. I want to use a public inner class of javax.faces.application.StateManager, named SerializedView, but this class cannot be found when I try to import it with the following statement: 
import javax.faces.application.StateManager.SerializedView; 
JDeveloper just says: 
Imported class 'javax.faces.application.StateManager.SerializedView' not found 
I already successfully use many other javax.faces classes, like StateManager... 
Any help would highly be appreciated, since this is a real blocker for me. 
 
Regards,
Matthias

Hi again! 
 
The problem is solved for the most part now. Compilation works fine, although the Java editor says the class SerializedView cannot be found. 
 
So the Java editor's behavior is still strange...

Why inner classes cannot have static declarations ?

Hi Friends,
When i tried to make static declarations on a inner class which is non static, i am getting compilation error saying "inner classes cannot have static declarations". I want to know reason behind this implementation.
Code which i have tried:
public class TestOuter
class TestInner{
static int i =10;
public static boolean validate(int a){
if(a==0)
System.out.println("Invalid data");
return false;
return true;
public static void main(String a[]){
boolean result = new TestOuter.TestInner.validate(0);
System.out.println("Result="+result);
Thanks,
Shiju V.

so I think if the
outer class is not static , then Inner class can't be
static as well. This is incorrect. An enclosed class can be indeed static while the outer is not, and vice versa.
The difference between static/non static in regards to enclosed classes is that the static ones are 'top-level' and cannot access the members of the enclosing class.
The effect of making an enclosed class static means there is only one instance of any variables, no matter how many instances of the outer class are created. In this situation how could the static inner class know which variables to access of its non static outer class. Of course the answer is that it could not know, and thus an static inner class cannot access instance variables of its enclosing class.
Now, regarding non-static inner classes, and trying to give a valid answer to the original post:
As with instance methods and variables, a non-static inner class is associated with an instance of its enclosing class and has direct access to that object's instance variables and methods.
TestOuter outer = new TestOuter();
TestOuter.TestInner inner = outer.new TestInner();Because an inner class is associated with an instance (inner class implicitly keeps a reference to the object of the enclosing class that created it), it cannot define any static members itself. Static members cannot access the this pointer.
So, in an ordinary (non-static) inner class, the link to the outer class object is achieved with a special this reference. A static inner class does not have that special this reference, nor would a static method/variable of an ordinary (non-static) inner class.

SSIS is not running in 64 bit production server - Error Class cannot be found while running from c# web application

Full error message:
An Integration Services class cannot be found. Make sure that Integration Services is correctly installed on the computer that is running the application. Also, make sure that the 64-bit version of Integration Services is installed if you are running a 64-bit
application
I have developed SSIS package in my development machine where the OS is 64 bit and sql server 2012 is installed.
The package has excel source and oledb destination. Excel files can be both .xls and .xlsx format. Since i want to run both xls and xlsx format i have installed
32 bit Microsoft Acess database engine form the below link, then both xls and xlsx format worked.
.xls - 32 bit
.xlsx - 32 bit and 64 bit is available. So in common i have to run it in 32 bit.
I have set Run64BitRuntime to False and ran package. it is working fine. I cannot set Run64BitRuntime to True and run the packages. Because i have office products installed on my machine which is 32 bit. if try to install 64 bit Microsoft Acess
database engine redistributable pacakage from below link , it is throwing error saying that, already office 32 bit product is installed so uninstall 32 bit product and install 64 bit.
Excel connection string is Ace database engine only. everything works fine.

Now i am trying to invoke package from c# code by using Microsoft.SqlServer.ManagedDTS.dll and it is also working fine in my dev machine.
When i deploy the web application in production am getting the error while invoking package. the full error message is posted in 1st line of this thread.
Then i tried to execute the package in production server by using dtexec utility, it is working fine. I tried both 32 bit and 64 bit dtexec utility by going to specific path (program files(x86) and Program files) via command prompt.
It is all working fine. So the error coming when i invoke from web application. My guess is ManagedDTS causing problem.
Where can i find 64 bit Microsoft.SqlServer.ManagedDTS.dll
or is it because of any other problem. i have checked below links, still problem not resolved.

1) "I have set Run64BitRuntime to False and ran package" -> this is not valid outside of your development environment, it is made for simulation purposes as all the dev tools are 32 Bit
2) "Where can i find 64 bit Microsoft.SqlServer.ManagedDTS.dll " is basically SSIS. It is quite possibly the culprit. I am inclined to think you attempt to run the package where there no SSIS installed.

Why Inner class cannot access static variables

Why is it that inner class can use only static final variables of the outerclass, and not ordinary static variables of the outer class. "Yes the JLS sepcifies that only final static variables can be used inside an inner class, esp a non blank final variable". But why this restriction.
Thanks.

so what are final static variables treated as if they
are not variables. So if the final static value is
not loaded when the class is loaded how will the
class know about the value.??The actual value wil be substituted for the name of a static final value at compile time. That's why you can use them in switch statements where you can't use any variable variable.
This is something to watch out for, by the way, because if you use a public static final value from one class in another the actual value will be compiled into the using class, so if you change the value where it's defined the class using it will have the old value until it's recompiled.

Class cannot be found

Hi guys..
After install JBuilder8, i got this error msg:
"P1Q3.java": Error #: 750 : initialization error: com.borland.compiler.symtab.LoadError: java.io.IOException: class not found: class java.lang.Object
Can you guys solve this error for me?
Thanks

This is because you have installed JBuilder twice?
You must go to: tools\configure JDK and remove the "old jdk".
Then add JDK again...

The "-cp ." tells Java to ignore the CLASSPATH variable and just look in the current directory instead. You probably had the location of StdIn on your CLASSPATH variable.
What you need to do in this case is to add the current directory "." to your CLASSPATH variable.

DRM, NetGroup, SystemUpdater classes cannot be found

Hi,
Today I've downloaded a fresh copy of Flash Builder Standalone, with Flex v4.1 coming installed with it. I'm trying to add OSMF swc to my existing project, but I keep running across the following errors:
1046: Type was not found or was not a compile-time constant: DRMAuthenticationCompleteEvent.
1046: Type was not found or was not a compile-time constant: DRMAuthenticationErrorEvent.
1046: Type was not found or was not a compile-time constant: DRMErrorEvent.
1046: Type was not found or was not a compile-time constant: DRMStatusEvent.
1046: Type was not found or was not a compile-time constant: NetGroup.
1046: Type was not found or was not a compile-time constant: SystemUpdater.
I've followed the swc install instructions as carefully as possible, but it appears as though some swc that I've downloaded within the most recent version of Flash Builder is not up to date?

It is not, it's a normal flex app. I thought it might be because the projects were older ones and perhaps they pointed to some other playerglobal.swc in their .actionscriptProperties file, but I have created a new project and added simple code and I still see the same issue.
I've been able to reproduce quite quickly with a fresh install of Flex Builder.
Download the latest version of Flex Builder 4 for Mac
Create new project.
Follow instructions in OSMF 1.5 Sprint 3 Release Notes.pdf -
Select the project folder and choose File > Properties. In the Properties window, select Flex Compiler.
Verify the Flex SDK version. OSMF should work on any Flex SDK version, but the sample apps that we ship with may be created with Flex SDK 3.2 or above.
Set Require Flash Player version to 10.0.0. In order to install/update Flash player, please go to
Copy OSMF.swc on to your local machine.
In your Properties window of your project, select the Flex Build Path ‐> Library Path tab
Select Add SWC. Add OSMF and click Finish.
Flash Builder 4 users must change default SDK version to Flex 4.0 and check the “Use Flex 3 compatibility mode” checkbox to avoid compile errors.
Use the following as application code:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
 xmlns:s="library://ns.adobe.com/flex/spark"
 xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
 <fx:Declarations>
 
 </fx:Declarations>
 <fx:Script>
 <![CDATA[
 import org.osmf.media.DefaultMediaFactory;
 import org.osmf.media.MediaFactory;
 var mediaFactory:MediaFactory = new DefaultMediaFactory()
 ]]>
 </fx:Script>
</s:Application>
When I try to compile this, I cannot because of the errors I've listed above. I'm using flex 4.1, and this happens regardless of how I set the compatibility mode. Thoughts?

Inner Classes - when to use with Swing?

Hi again,
I was creating a GUI with JTabbedPane as content pane, while doing the single panes in the different tabs i started wondering about some design issues.
Let�s say you have a pane that is composed of 3 "subpanes" ( containing all the interaction components ). Should i write "normal" classes for each of the subpanes or is it more reasonable to define them as inner classes of the "main" panel - that�s at least what i thought because those 3 smaller panels are bound to the main panel for their lifetime...
Any design tips about inner classes and swing or even inner classes in general, i�d really appreciate.
Thx

The concept of inner classes design in java is (I hope) they provide 'composite aggregation' relation with the contained class.
Means that the (inner) class cannot exists alone and provide functionalities like other classes. Inner classes refer to the "contains" relationship in the UML.
The other regular associations say, having a value oject model to an UI are Structural Aggregation, means that the value object can be used in the UI and also separately.
For your case the inner classes are not suitable. You may have to find a suitable mechanism to get the individual tab panes. Probably use an interface to bridge the three tab panes and use an manager class, pass and id to the manager class and get the required Tabbed pane.
Thanks,
ananth

Compiling inner classes

Hi,
I have an applet with inner classes (the applet is contained in a single .java file). When I compile the applet, a number of *$*.class files are created for the inner classes. However, a friend of mine compiles the same .java file and he gets a single .class file. He can't see any files corresponding to the inner classes. My compiler is version 1.4.0, his is 1.4.2. Can you suggest how my friend can generate the *$*.class files corresponding to the inner classes?
Thanks for your help.
Miguel
PS If the .jar file does not contain the *$*.class files, then appletviewer can't find the inner classes.

Let me try again. My friend gets a single .class file.
If he invokes the applet like this:
<APPLet CODE="myapplet.class" WIDTH=100 HEIGHT=100>
he has no problems at all.Because all the necessary files are there. Including the inner class files. Why he doesn't see them is another problem.
However, if he puts his class file in myjar.jar and
invokes the applet like this:
<APPLet CODE="myapplet.class"
ARCHIVE="myjar.jar"
WIDTH=100 HEIGHT=100>
then his inner classes are not found by appletviewer.Because he didn't put the inner class files in the jar. Why he didn't put them is another problem.
There is abosolutely no other explanation I can see.

Your Opinions: Inner Classes Need static Members

Hi All,
I want to solicit opinions for a minor change to the way inner classes work. I submitted this as an RFE to Sun and they rejected it, really without giving a reason. I'd like to know your opinions. If there is strong support I will repost the RFE.
As you probably know, inner classes cannot have static members. The following generates a compiler error:import java.util.*;
public class MyClass {
   class MyInnerClass {
      // Next line causes compiler error...
      static Map m = new HashMap();
}In order to get around this you have to make the Map variable a static member of the containing class:import java.util.*;
public class MyClass {
   static Map m = new HashMap(); // so much for encapsulation...
   class MyInnerClass {
}I am suggesting that inner class be allowed to contain static members. Here's my reasoning...please comment:
There are times when members (i.e., fields and methods) rightfully belong to the class as a whole, not to any particular instance of a class. I'm sure we've all found times when it was necessary to have static members in our classes. The same issues that necessitated using static members in top-level classes make them desirable for inner classes as well.
Designing a class as an inner class is a step toward encapsulation. By forcing static members that logically belong in an inner class to be declared in the containing class is to crack the encapsulation, IMHO.
Even though a containing class has access to all of an inner class' members (including private members) and vice versa, I think the notion of inner static members still is more OO-ish.
What are your opinions? Would allowing inner classes to contain static members make Java more object oriented? I think it would.
Technically, I don't think there's any reason this cannot work since the JVM has no notion of inner classes, per se.
What do you think?

an inner class is effectively a non static instance
variable of its enclosing class. Instance member, but not a variable. it's a class, a type, not a variable.
>
I think the problem here is that making a field static
means more than just that that field and its value are
common to every instance of the class. It means that
the value is valid without an instantiation of that
class.
Since the class itself must be instantiated (it is
not static), What do you mean, excatly, by "_must_ be instantiated"? You are not ever "required" to instantiate anything unless you want to use it.
you can't have static member data inside it. I don't see how this follows from the previous part of the statement.
How would you reference the static member data of
the inner class? You would have to specify an
instance of the inner class, and since this breaks
the meaning of static, you can't have static members
in an inner class.How about outerObj.InnerClass.staticMember The syntax is well defined. The question at hand is, do we really want to allow this? The syntax to do this should only be an issue after that question has been answered in the affirmative. The people at Sun have decided not to allow it, so for now, syntax is a non-issue.
>
if you wanted a static member in an inner class you
could put it in a super class of the inner class...Or in the enclosing class, as suggested in the orginal post.

Extending a member inner class

I have a class
public class A{
class InnerClassB{
Now the question is how to extend the inner class would it be
class ExtendingInnerClassB extends A.B{
or else?
I am not sure anybody knows?

Regarding inheritance from inner classes you must define your constructor:
public ExtendedInnerClass(EnclosingClass EC) { EC.super(); }
why?????
well
1. Where is the handle? The handle is an internal thing which is designed to accept the enclosing class. It is something which is not in the programmer's control. when there is an inner class, it is natural that the inner class cannot exist without its outer class. And that is the reason why the instantiation of an inner class is done using new OuterClass().new Innerclass(). U can see that the innerClass object is created based on the outer class object (assuming that the inner Class is not static). I hope that this is clear. Now .. the whole point is how does the compiler know that the Outerclass is the enclosing class? When the above line is compiled, the tricky handle in the inner class is assigned to the Outer class. So any reference henceforth is made based on this handle.
2. In the Inherited Inner class, there is no way to assoicate the handle in the above manner. Hence we are forcing by calling the super().
3 Otherwise why not simply create with: new InheritedInnerClass(EnclosingClass)? This is not possible. What if the inherited inner class needs a constructor in the above manner. That is assume that there is a class A. Then if the Inner Class needs the constructor to be InnerClass(A a, EnclosingClass b) for some other purpose, then what judgement can the compiler take? So that answers the question Can't the compiler compile the inherited inner class assuming a handle to the enclosing class and then force an instance to be created using the EnclosingClass.new syntax? Becuase in this case it cant go by any assumption.
4. Maybe the compiler designers can make some change such that the inherited inner class should have all its constructors beginning with the enclosing object and there should be atleast one constructor. But somehow I feel that it is too much of asking.

Serializable inner classes

How does one deal with the serialVersionUID issue with non-static member classes? Is this the best we can do?
class A implements java.io.Serializable {
static final long serialVersionUID = 42;
@SuppressWarnings("serial") class B implements java.io.Serializable {...}
}MC

How interesting. I never even tried! The language specs say: "inner classes cannot have static members, except for static final fields that are initialized to constants". This means that the declaration of m is valid but the declaration of n is rejected at compile-time:
class A implements java.io.Serializable {
static final long serialVersionUID = 42;
class B implements java.io.Serializable {
 static final long serialVersionUID = 42;
 static final String m = "42";
 static final String n = String.valueOf(42);
}MC

BUG: Oracle Java Compiler bug with anonymous inner classes in constructor

The following code compiles and runs just fine using 1.4.2_07, 1.5.0_07 and 1.6.0_beta2 when compiling and running from the command-line.
It does not run when compiling from JDeveloper 10.1.3.36.73 (which uses the ojc.jar).
When compiled from JDeveloper, the JRE (both the embedded one or the external 1.5.0_07 one) reports the following error:
java.lang.VerifyError: (class: com/ids/arithmeticexpr/Scanner, method: <init> signature: (Ljava/io/Reader;)V) Expecting to find object/array on
stack
Here's the code:
/** lexical analyzer for arithmetic expressions.
Fixes the lookahead problem for TT_EOL.
public class Scanner extends StreamTokenizer
/** kludge: pushes an anonymous Reader which inserts
a space after each newline.
public Scanner( Reader r )
super( new FilterReader( new BufferedReader( r ) )
protected boolean addSpace; // kludge to add space after \n
public int read() throws IOException
int ch = addSpace ? ' ' : in.read();
addSpace = ch == '\n';
return ch;
public static void main( String[] args )
Scanner scanner = new Scanner( new StringReader("1+2") ); // !!!
Removing the (implicit) reference to 'this' in the call to super() by passing an instance of a static inner class 'Kludge' instead of the anonymous subclass of FilterReader fixes the error. The code will then run even when compiled with ojc. There seems to be a bug in ojc concerning references to the partially constructed object (a bug which which is not present in the reference compilers.)
-- Sebastian

Thanks Sebastian, I filed a bug for OJC, and I'll look at the Javac bug. Either way, OJC should either give an error or create correct code.

Inner classes generated by xmlbeans

I was given a library to use that most of it was created with the apache xmlbeans framework. The following code works within the eclipse java ide but JDeveloper does not find the inner factory class of the QueryEnterpriseAckDocument class. How does JDeveloper handle working with inner classes. This may be an issue that requires going back to eclipse as the ide.
     QueryEnterpriseAckDocument ackDoc = QueryEnterpriseAckDocument.Factory.newInstance();
     QueryEnterpriseAckDocument.QueryEnterpriseAck ack = ackDoc.addNewQueryEnterpriseAck();

Is there some kind of meta-specification for JSR 269 that explains the design goals? Not really, only what is here http://jcp.org/en/jsr/detail?id=269
With such a document, it might also be easier to figure out how processors are supposed to work.JSR 269 is designed to permit solutions to various complex scenarios rather than provide solutions. Those scenarios and their intended solution are not often obvious from the API specs.
You might like to take a look at https://hickory.dev.java.net/ where I have a project to supply some tooling to assist annotation processor authors, and a wiki to document things. Allocating time to this is not easy, but the 3 packages in the API there are pretty robust. The test cases in source code for those have plenty of examples of some of the more complex design goals, such as the ability to write an annotation processor which works correctly in an incremental compile scenario, when the generated file derives from more than one source file, not all of which may be included in an incremental compile.
Other than that, if you have any particular questions, just ask in this forum, and Joe (JSR 269 spec lead) or myself should be able to answer them for you.

Deployment problem: Inner class not included

Hi, All:
I am trying to deploy my Java application using JDeveloper 3.2. I was be able to successfully deployed it when I first designed the project, even some of the files also have inner classes. Now I have added some new inner classes to a public class and tried to re-deploy it. However how hard I tried (I have tried to rebuild the project, redefine the depoyment profile, even tried to add these class files directly through the advanced tab), the newly added inner class will not be able to be added to the deployed Jar file. I have checked the class files under myclass directory, and found all the inner class files are there, and I can run the application in JDeveloper without any problem. I wonder if there is any tricks to solve this problem. (Other than use the jar command).
Thanks,
Peter

Also, it's probably a good idea to name your packages different than your classesMoreover, common naming conventions dictate you should never even use capitals in your package names if I'm not mistaken. Whereas class names should always at least begin with a capital.
This will help prevent a lot of confusion, both for the developer and the IDE. ;-)
