Redirecting the output of java compilation to a text file

i tried to redirect the result of the java compilation to the text file using
javac zz.java > compile.txt
It works if the program has no errors and it did not work if it have errors. Wat is the reason it did not work for wrong programs.

This has nothing to do with Java. It's your command shell.
If you're on linux, then it's because the errors go to stderr and you're only redirecting stdout. I assume Windows is similar, but I don't know much about that.
For bourne shell family on linux (sh, ksh, bash, zsh), you'd do
javac zz.java > compile.txt 2>&1I'm not sure what the syntax is for csh family.

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.

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.

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:

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 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".)

Storing Compilation errors in a File or String

import com.sun.tools.javac.Main;
String Args[] = { "-classpath", ".;C:/j2sdk1.4.2_05/bin;", "-nowarn", fileName};
I am using the command Main.compile(Args); to compile a Java File.
It will return 0, if the file is compiled without errors.
If errors exist, I want to store the errors in file.
How to do that, if i use the command Main.compile(Args)

Hi
You can keep appending the messages to the existing file(APPEND MODE).
You can use FILE_GET_ATTRIBUTES of Class CL_GUI_FRONTEND_SERVICES or FM EPS_GET_FILE_ATTRIBUTES to get the application file details.
Use FM SXPG_COMMAND_EXECUTE to delete the file on application server once the duration is greater than 45 days.

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.
DataBrokerClass.java:963: cannot resolve symbol
symbol : method getArray (java.util.Map)
location: class oracle.sql.ARRAY
Object[] AdvoIntCfgHhcRecObj = (Object[]) advointCfgHhcRecArrOut.getArray(map);
^
Note: DataBrokerClass.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
1 error

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:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 14

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.

Compile error for .ejb file

I have one .ejb file calling another .ejb. I do this using typical lookup("ejb.xxxHome");
Everything seems to resolve in workshop. But when I compile, I get can NOT resolve
error.
Appearently, .ejb does not recognize Bean and Home .java files. Any alternative?

Hi.
The problem is that DragManager.acceptDragDrop expects a
UIComponent but Event.target is typed as Object. You need to cast
the target as a UIComponent. Try this:
DragManager.acceptDragDrop(UIComponent(event.target));

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

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
