Java compile error

hi
im currently running java 1.4.2 on ubuntu linux.
i can compile and run my simple one class programs without any probs.
recently i have tried to compile a class which uses objects defined in other classes in the same directory and it wont compile. it has problems with any objects not defined in that particular class. error message says object cannot be resolved to a type.
any help here would be appreciated

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.

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.

Java compilation error messages

Is there any way for HTML DB to return error messages during Java compilation? Every create java command I submit -- unless there is a grievous syntax error -- seems to return statement processed:
Given....

Er....yeah....but do you have any idea why the SQL Command Processor would not return any errors when trying to compile a class with a non-valid dependency?
Another example:

Java compilation error in Web Dynpro

Hi Experts,
I have to write one line like this in Java program of Web Dynpro:
wdContext.currentPritemElement().setPreq_Price("1.544");
This is not getting compiled. The error is "The method setPreq_Price(BigDecimal) in the type IPrivateMyView.IPritemElement not applicable for arguments(string)".
It looks like there is datatype mismatch and due to this we are getting above error. We Can we do some like typecasting etc to sort out the issue. If yes, how we can do so.
Regards,
Ravindra

Hi Ravindra,
The error is because of data type mismatch.
You can do like this:
wdContext.currentPritemElement().setPreq_Price(new BigDecimal(1234));
Thanks.
Best Regards,
Shiva

Java Compilation error.

Trying to compile java file and got following error. Java version I am using is 1.4.2. I tried to comple same with
-source 1.3 option also but not luck. Any help would be appriciated.

it has nothing to do with the java version or java itself really, you are trying to call a method that does not exist. I am not the worst person on earth, so I did some investigating on the net. It turns out that you are incorrectly using a Map, you want to use a Hashtable in stead.
Just for reference, what I did to investigate is, I typed "oracle.sql.ARRAY" into google and that gave me the javadocs for this class.

Java Compile Error Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 14 for iOS

When compiling one of my projects, I am getting this error suddenly:

Compilation failed while executing : ADT
but only when targeting iOS. fo Android only, it works fine. Anyone have any ideas? I also logged it as a bug.

I get the I/O exception while reading: D:\Java\HelloApplet (The system cannot find the file specified). I have previously compiled HelloApplet.java into HelloApplet.class using javac.exe
the two include statements in the sample HelloApplet I'm using are
import java.applet.*;
import java.awt.*;
I also have a ComponentEventTest.java file which I've made into a class with these two
include statements:
import java.awt.*;
import java.awt.event.*;
I can however compile .java files which have no include statements.
I take it that my classpath is not set correctly. Like I said earlier, I'm using winxp
and trying to set the classpath variable under system. I have tried under user too. The path names I've tried setting are C:\Program Files\Java\jdk1.5.0_02\, C:\Program Files\Java\jdk1.5.0_02\lib, C:\Program Files\Java\jdk1.5.0_02\include, and C:\Program Files\Java\jdk1.5.0_02\;C:\Program Files\Java\jdk1.5.0_02\lib;C:\Program Files\Java\jdk1.5.0_02\include.
How can I correct this? If it's possible, I would like to set a variable in windows
versus having to type extra commands at the command prompt everytime I try
to run a java class with java.exe. Any help would be much appreciated

My first Java compile error!

I'm not new to programming but I am to Java, I like it so far and I know I have a long way to go.
I just started an online training course in Java and the second
program to write was this:
import java.awt.Frame;
import java.awt.Label;
public class HowdyWindow extends Frame {
public static void main(String args[]) {
new HowdyWindow();
HowdyWindow() {
Label label;
label = new Label("Howdy!");
add(label);
pack();
show();
I then compiled it and was met with this ugly statement:
Note: HowdyWindow.java uses or overrides a depricated API.
Note: Recompile with Xlint:deprecation for details
Did that, got this:
HowdyWindow.java:13 Warning:[serial] Serializable class HowdyWindow has no definition of serialVersionUID
public class HowdyWindow extends Frame {
2 warnings
As a newbie I have no clue, How could I ?
Please someone tell me what to do next, in Newbie terminology?

are they both warnings? errors you have to fix; warnings should be corrected eventually, but you can get by for now.
this is happening because the show() method is deprecated. you should use setVisible(true) instead. look at the javadocs and see what's what.
did you get a HowdyWindow.class file? if so, execute it and see what happens.

Xcode Java Compilation Error

Hello Everyone,
I am using XCode to develop a Java application. I created my main file and a bunch of other files (object oriented) that help out the main file by selecting Add > File & then choosing pure Java file.
When I run Build, they all compile just fine. However, when I create an object in the main file from a java class I wrote, it throws an error. For example
class A
Main()
create object B
//seperate file called b.java
class B
constructor()
some variables
Class A is not able to see Class B. Also, I was not able to see to my other files. Any ideas how I can fix this? I have been coding for a long time, but on Linux. I just started my transition to Mac. Thanks.

Java Compiler Error Export

Is there anyway to export the error results as a txt file when we compile java program in Windows XP CommandPrombt?

You can use System.setOut() and System.setErr() methods within Java, or you can use Windows' redirection capabilities (hint: see Windows Help for "redirect output".)

Fetch Document from workspace+java API+ObjectByPath.java compile error

Hi All,
(Hyo version: 11.1.1.3)
I was trying to export files imported into workspace. For testing purpose I imported P4S.pdf in 'Sample Content' folder.
While looking for various options I came across Java API for workspace.(See samples in C:\Hyperion\products\Foundation\workspace\SDK\samples\java)
I found a Java sample named "ObjectByPath.java". I complied (using JC.bat) and executed (with Execapi.bat) and came with this output:
C:\Hyperion\products\Foundation\workspace\SDK\bin>execapi ObjectByPath admin password localhost 6800 "Sample Content/P4S.pdf"
library not available, add it to your classpath: spf.jar
Path : Sample Content/P4S.pdf
Name : P4S.pdf
Path : /Sample Content/P4S.pdf
Mime Type: application/pdf
Class : com.sqribe.rm.DataObjectImpl
ObjectID : 0000013828cfc4b7-0000-a30d-7f000001
Unfortunately the object could not be exported. I checked the "ObjectByPath.java" file and I saw:
String path = args[4];
RMBase tObject = rep.getObjectByPath(path);
// tObject.toXML(System.out);
System.out.println("Path : " + path);
if (tObject instanceof BaseObject) {
BaseObject baseObj = (BaseObject) tObject;
System.out.println("Name : " + baseObj.getName());
System.out.println("Path : " + baseObj.getPath());
System.out.println("Mime Type: " + baseObj.getObjectType().getMimeType());
System.out.println( "Class : " + tObject.getClass().getName());
System.out.println( "ObjectID : " + tObject.getObjectID());
Note that the exported line is commented.
When I remove the comment and recomplile with JC.bat I get this error:
C:\Hyperion\products\Foundation\workspace\SDK\bin>jc ObjectByPath.java
ObjectByPath.java:32: unreported exception java.io.IOException; must be caught or declared to be thrown
tObject.toXML(System.out);
^
Note: ObjectByPath.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
1 error
Any idea how to resolve this issue.
Thanks,
Ankit

It says to add spf.jar to your classpath. Can you do a search on the file system for that file? If you find it add to your classpath.
By commenting that line out you just produced another, unrelated error.
Thanks

Oracle Java Compiler 11g - JVM ERROR

Hi Jdev Team,
I have an issue to report,
Sometimes when run a project and navigate through the pages, i get the following error message:
Oracle Java Compiler 11g
Unable to create an instance of the Java Virtual Machine
Located at path:
H:\jdevstudio1111\jdk\jre\bin\client\jvm.dll
The only way to solve this is delete the settings of the Jdev and the Jdev from the PC, and install again, with the associated waste of time as consecuence. Please you can give a light to resolve this issue? Thanks
Well i correct what i just said.
The problem doesn´t fix, with the erase of the jdev program folder or settings folder in windows user docs and settings. What else i can do!?, out of ideas in here.

out Error in Java compilation: \s7u.log (The system cannot find the file specified)
Any suggestion appreciated.
Daniel Huang

Having not seen this before, I assume that the issue is that the command line string is too long when Javac is invoked.
Here are a few things to reduce the size of the command line:
- do not use the CLASSPATH option, but set the CLASSPATH environment variable (you can to that in a .bat file)
- do not provide the .java files but rely on the implicit make capability in both, the SQLJ translator and the Java compiler. (Note: you must mention all of the .sqlj files that your program requires, do not rely on implicit make to find all of those.)
- you can perform the -ser2class conversion as a separate step (see the SQLJ FAQ), as well as the Java compilation
- there may or may not be a facility in your operating system to increase the size of the environment (and this may or may not have an effect on the maximum command line length)
- you could try to omit the -passes option and see if that helps (that may actually be where your invocation if failing in the first place, in that it cannot write to some temporary file).
Let us know how it goes. Thanks!

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
-- DO NOT EDIT THIS FILE - it is machine generated!
args JNI.ARGLIST;
-- Constructor for signature ()V
FUNCTION new RETURN ORA_JAVA.JOBJECT IS
BEGIN
args := NULL;
RETURN (JNI.NEW_OBJECT('tarek/Screen', '()V', args));
END;
-- Method: getHeight ()D
FUNCTION getHeight(
obj ORA_JAVA.JOBJECT) RETURN NUMBER IS
BEGIN
args := NULL;
RETURN JNI.CALL_DOUBLE_METHOD(FALSE, obj, 'tarek/Screen', 'getHeight', '()D', args);
END;
-- Method: getWidth ()D
FUNCTION getWidth(
obj ORA_JAVA.JOBJECT) RETURN NUMBER IS
BEGIN
args := NULL;
RETURN JNI.CALL_DOUBLE_METHOD(FALSE, obj, 'tarek/Screen', 'getWidth', '()D', args);
END;
BEGIN
NULL;
END;
