Java 1.4 compilation error

Hi
I am using JDK 1.4 to compile my source code which is compatable with JDK 1.3.1.
The source code was compiling fine . But when i use the JDK 1.4 i am getting the following comilation error in the following code snippet.
// Automatically-generated file -- do not edit.
package org.omg.CORBA;
import org.omg.CORBA.IDLType;
import org.omg.CORBA.IDLTypeHelper;
public class IDLTypeHelper {
Error:
----- \org\omg\CORBA\IDLTypeHelper.java:12: org.omg.CORBA.IDLTypeHelper is already defined in this compilation unit
import org.omg.CORBA.IDLTypeHelper;
Any help is appreciated
Thanks

Hello gkharishbabu,
The message appears to say that you are trying to import org.omg.CORBA.IDLTypeHelper into itself. Try commenting out the line:
import org.omg.CORBA.IDLTypeHelper;Hope that helps.

Simple Java created with compilation errors.

Hi,
While I am using Oracle for many years (currently 9.2.0.6.0) I am completely new to Java in the database.
I found a very simple example to get started (please see SQL*Plus dump below) ... but I get a compilation error. Can anyone tell what I am doing wrong?
SQL> CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED Fibonacci AS
2 public class Fibonacci
3 {
4 public static int fib (int n)
5 {
6 if (n == 1 || n == 2)
7 return 1;
8 else
9 return fib(n - 1) + fib(n - 2);
10 }
11 }
12 /
Warning: Java created with compilation errors.
SQL> show errors java source Fibonacci
No errors.
SQL>
(It must be a simple thing, the example I found seems correct, but what about grants, settings etc.)
Thanks in advance,
Stefan

Stefan,
I cannot see anything in your code that would cause a compilation error. However, according to the example in the "Oracle 9i SQL Reference", it looks like you need to enclose the name in double quotes, as in:
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "Fibonacci" AS ...Alternatively (and this is the way I do it), you could compile the class outside of the database, and load the compiled class file. Just create a file called "Fibonacci.java" (that contains your java code), compile it, and then use the "loadjava" tool to load the "Fibonacci.class" file into the database. Please refer to the Oracle 9i Java Developer's Guide for more details.
Good Luck,
Avi.

I am able to compile a java file in eclipse inspite of compilation errors shown in eclipse and a .class file is generated

Hi,
I had a java file with compilation errors as shown in eclipse IDE.
But the class file is still generated in the classes folder on building and pressing clean the project.
I confirmed that the class file has an updated time stamp and also that a System.out.println() statement that i added was indeed printed out when this class was encountered during the running of a web application in which this class was called somewhere.
(The java class has no subclasses and it is a single class with public modifier).
How does it happen so?
Regards,
Karthik.

As far as I know, the java code is compiled in Eclipse as soon as you save it. i.e. press CTRL+SHIFT+s
as far as the build is concerned, in case you have a build file where you specify how to make a jar file, the location the jsr file is to be placed, only then you have to build the project. However again, as far as just simple compile is concerned as soon as you save the files are compiled. And show you the errors if any in the tasks window.

Maybe your EJB have static methods. Remove the 'static' modifier and retry.

Internal compilation error

I have got the following error message while compiling a small Java application:
"Internal compilation error, terminated with a fatal exception". I am using EA1. Need help.
Thanks...

I am having the same problem. I cannot find the "use JavaC" checkbox that you refer of.
I am using J2SDK1.4.2_10 and the base installation of 10g (10.1.2 - production).
I set the "SetJavaHome" variable in the jdev.conf file correctly
I installed jDeveloper into the directory "c:\jdev"
I have set the JAVA_HOME and the CLASSPATH variables.
I tried to uninstall everything and install the 10g FULL install with jdk1.4.2_06 (10.1.2 - production) but had the same problem.
Still the same error every time I try to compile i simple "Hello World" program.
Also the "Profiles->Development->Libraries" tab in the "Tools->Project Properties" causes a null pointer exception when I try to select it.
Any help would be appreciated. I need to get this up and running as soon as possible.

How to track the information/error of java code while compiling.

Hi,
I want all the information or errors of java code during compilation.
So that I can use this information or I can show these errors with different style.
How to get the java syntax errors?

Hi,
I want all the information or errors of java code
during compilation.
So that I can use this information or I can show these
errors with different style.
How to get the java syntax errors?Redirect the STDOUT/STDERR from the the JAVA/JAVAC command to a file is one way...
For instance at the commmand line:
javac myClass.java > STDOUT.txt 2> STDERR.txt (Works for Unix variants or Windows OS's)
Then you can do what ever you want with the data contained in the files.
Hope this helps

Problem When Import Java Class -compilation error

Hi all
I made a java class that has methods to return Screen width and Height .
package tarek;
import java.awt.Dimension;
import java.awt.Toolkit;
public class Screen
Dimension dim ;
public Screen()
dim = Toolkit.getDefaultToolkit().getScreenSize();
public double getWidth()
double w = dim.getWidth();
return w;
public double getHeight()
double h=dim.getHeight();
return h;
I made the jar file " screen.jar" and make it ready to use in form builder
I opened form builder and make import java class (From program>import java class>choose the class anc click import)
The class now imported successfully and the PL/SQL package body is:
PACKAGE Screen /* tarek.Screen */ IS
-- DO NOT EDIT THIS FILE - it is machine generated!
-- Constructor for signature ()V
FUNCTION new RETURN ORA_JAVA.JOBJECT;
-- Method: getHeight ()D
FUNCTION getHeight(
obj ORA_JAVA.JOBJECT) RETURN NUMBER;
-- Method: getWidth ()D
FUNCTION getWidth(
obj ORA_JAVA.JOBJECT) RETURN NUMBER;
END;
Now I made a button on the form and i WRITE THIS CODE TO INVOKE THE CLASS on when_button_pressed
DECLARE
vScreen_Class ORA_JAVA.JOBJECT;
BEGIN
vScreen_Class := SCREEN.NEW;
END;
My problem is I have compilation error
error 306 AT LINE 5 , COLUMN 25
wrong number or types of argument in call to "NEW"
I do not know what is the reason of this compilation error?
Is it because the method in java return "double datatype" while in oracle return "number datatype"
Please help
Edited by: [email protected] on Dec 28, 2009 10:24 AM

Sarah, I ca not move my thread to JDeveloper because it is not java issue. The problem is with my PL/SQL code and the way I make Import Java class to forms Builder. The Java code is OK.
Andreas Thank you so much for replying. In fact I made a full compile "Ctrl+Alt+K". but still error
The following is the package Body
PACKAGE BODY Screen IS

FUNCTION new RETURN ORA_JAVA.JOBJECT IS

Deployment Error -- JSP Compilation Error: java.lang.OutOfMemoryError -- nu

When I deploy WAR files with the precompile jsp option, I receive the following error:
Deployment Error -- JSP Compilation Error: java.lang.OutOfMemoryError -- null
Is there a way for me to precompile my jsp's without using this process? Once this blows up, the admin server gets hosed. This is very frustrating. Any suggestions would be appreciated.
Regards,
Joshua

You need little more memory :-), use java param -mx512M.
You can adjust it in OC Server properties
AS > OC4J_home(demo) > Server Properties
section Multiple VM Configuration, Command Line Options
Java Options: -mx512M

Java compile error for removed API

Hi,
What are the Java compile errors for API that has been removed?
As I understand it, API elements are deprecated and not removed from the API immediately, but will be removed in future releases or after so many years.
When Java code is compliled in a higher Java version, and the API has finally been removed - what are the errors that will be ouput in the log?
Thank you for your time.

WalterLaan wrote:
And if you recompile one with a method removed that the other use and then run the other you would get a NoSuchMethodError (or more generally just an error sub class of LinkageError).
Not that you should be catching those unless you accept classes from the user (as plugins).Presumably you mean he should not be catching them?
@OP: In general, you should not catch unchecked exceptions. These are RuntimeException, Error, and their descendants. There are exceptions, such as at "layer boundaries," or when you don't want errors in one module/application/plugin/etc. to affect or prevent processing in others.

Do java programms after giving compilation error generates .class file?

Do java programms after giving compilation error generates the .class file?
Do any outer class may have the private as access modifier?
If someone asks you that -do any program in java after giving a compilation error gives the .class file -do any class except(inner class)
be defined as private or static or protected or abc or xxx Now type the
following program
private class test
public static void main(String s[])
System.out.println("Hello!How are You!!");
-Compile it.... You must have
received this error test.java:1:The type type can't be private. Package members are always accessible within the current package. private class
test ^ 1 error
Here please notify that compiler has given the
error not the warning therfore .class file should not be created but now type
>dir *.class
___________ and you will see that the
test.class file existing in the directory nevertheless this .class file
is executable. if you will type __________________ >java test
it will
wish you Hello! and suerly asks you that How are You!! ________________!
You can test it with the following as acces modifiers and the progrm will run Ofcourse it will give you compilation error.
protected
xxx
abc
xyz
private
Do you have any justification?

Hmm,
I've been working with different versions of jdk since, if I'm not mistaken, jdk1.0.6 and never was able to get *.class with compilation errors. It was true for Windows*, Linux, and Solaris*.
About the 'private'/'protected' modifier for the type (class) - it makes perfect sence not to allow it there: why would anyone want to create a type if no one can access it? There should be a reason for restricting your types - let's say, any inner class can be private/protected.
For ex., you shouldn't have compile problems with this:
class Test
public static void main(String s[])
System.out.println("Hello!How are You!!");
private class ToTest{}
Sorry, but I don't really know where you can read up on that.

Compilation Error in basic java class

Hello,
I am newbie. And, I have developed following java classes. But the child class is results in error. Below is step by step event. What am I doing wrong?
Step 1. Created a compiled class Shirt(parent). No issues
public class Shirt {

public String description = "description required";
// color codes
public char colorCode = 'U';
public double price = 0.0;
public int quantityInStock = 0;

   System.out.println("Shirt price: " + price);
   System.out.println("Quantity in Stock :" + quantityInStock);
} // end of method

    23 }This is basically from the Fundamentals of the Java ^TM^ Programming Language SL-110-SE6 Student Guide(pages 9-12 & 9-13). We are working on Encapsulation if that makes any difference. Maybe it's just me but this book is not very new programmer/user friendly. At least in my opinion. I find it very frustrating that I can't even type in examples from the book and get them to work.
I have tried the javac -cp . ShirtTest.java suggested here but get the same error. I have removed all *.class* files and still no luck.
OS:
uname -a
SunOS 5.10
JAVA:
java -version
java version "1.5.0_26"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_26-b03)
Java HotSpot(TM) Server VM (build 1.5.0_26-b03, mixed mode)
Anyway, any help would be appreciated.
