Compiling utf-8 source java files

Hi there,
Is it possible to compile java applications with the source files encoded in utf-8 format?

Thank you for your reply, but i have an error when i
compile like that
error: compiler message file broken:
key=compiler.err.java.io.UnsupportedEncodin
gException: utf8 arguments=null, null, null, null,
null, null, null
1 error
What is error mean??The following all work with the Sun jdk 1.4
javac -encoding UTF8 MyClass.java
javac -encoding utf8 MyClass.java
javac -encoding utf-8 MyClass.java
If the encoding is wrong then it produces the following error
error: unsupported encoding: XXXX
And that is not the error that you are getting. Which at the very least suggests that you are not using Sun 1.4. So it might help to know which version you are using.

How to compile and run a .java file from another java program

hello,
can any one tell me how to compile and run a *.java* file from another java program which is not in same directory?

Well a smarter way of implementing this is by using a solution provided by Java Itself.
If you are using J2SE 6.0+ there is an in built solution provided along with JDK itself and inorder to go ahead with solution the below are set of API which you;d be using it for compiling Java Programs (Files)
http://java.sun.com/javase/6/docs/api/javax/tools/package-summary.html
How do i do that ??
Check out the below articles which would help you of how to do that

Now once we are done with compilation.In order to run a Specific class all you ought to do is create an object and its specific methods of a specified class included in the CLASSPATH which you can manage it easily by usage little bit reflections.
Hope that might help :)

Oracle EBS R12 - how to compile jsp and keep .java file

Hello.
When I compile the jsp file, it will create the _pagename.class file into $COMMON_TOP/_pages directory. Some of the time it also keep _pagename.java file in there.
How can force the compiler to keep the java file always. I am using following command which creates _pagename.class file.
perl $FND_TOP/patch/115/bin/ojspCompile.pl --compile -s 'ptcResponse.jsp' --flush
It keeps the _pagename.java file some of the times and not other, example if the compilation fails then java files stored there otherwise only class.
There has to be some way/location to see/keep the _pagename.java file, we need them for troubleshooting runtime error.

It keeps the _pagename.java file some of the times and not other, example if the compilation fails then java files stored there otherwise only class.
This is an expected behaviour.
There has to be some way/location to see/keep the _pagename.java file, we need them for troubleshooting runtime error.
The "perl ojspCompile.pl" command doesn't offer this -- Issue "perl ojspCompile.pl" and you will see what options are available.
Your option is to keep/save the java files in a different directory.
Thanks,

I want all three files to compiled successfully.If it is compiled only then I will continue on Unmarshalling process

I suspect you are trying to compile the files one by one. You may also be trying to compile them disregarding the package structure.
From your post, I gather these files are in the package: com.geindustrial.sqms
Therefore, if they are not so already, put them under a directory structure:
com/geindustrial/sqms
and then compile with:
javac com/geindustrial/sqms/AddCtq.java com/geindustrial/sqms/Ctq.java com/geindustrial/sqms/VariableData.java
(The above is all on one line.)

JSP/EJB compilation: don't put .java files in EJB jars!

I was having trouble compiling a JSP that uses an EJB remote interface.
          The Weblogic console printed an error like this:
          Thu Aug 31 14:13:58 PDT 2000:<E> <ServletContext-General> Compilation of
          D:\weblogic\myserver\classfiles\jsp_servlet\_hl
          og.java failed:
          D:\weblogic\myserver\tmp_deployments\ejbjar-6787.jar(hlog/ejb/LogEntry.java):5:
          class LogEntry
          is public, should be declared in a file named LogEntry.java
          (source unavailable)
          1 error
          The fix was not to include source files in my EJB jar. Before I was
          using a simple jar command:
          >jar -cf hlog.jar hlog META-INF
          Which of course included both class and source files in the jar (I
          didn't see the harm in this).
          I changed to:
          >jar -cf hlog.jar hlog\ejb\*.class META-INF
          and the problem went away.
          Thought this might save y'all some time and grief...

Compiling / Running a Java file in JSP

Hi,
ok, I have a jsp page, which we will call page 1. Once I go to that page, I all I want it to do is compile a certain file.java, and then run the file.java. The user doesn't actually know that this is going on in the background. Page 1 automatically redirects the user to page 2 (also a jsp page).
The java program that I created (that was previously compiled and ran) creates a special javascript file. After running the file.java in page #1, the java file creates a javascript file that will be used in page 2 to display a tree node (group of information).
so, right now, I'm trying to figure out how to write the jsp code that will tell how to compile and run a java file. I was thinking about using javabeans before, but I think you HAVE to actually display the contents of the java file into the jsp (I think). Anyhow, thanks for the help!

sorry about being ambiguous before. What I mean by
running a java file was that I already created a java
file. I don't want to hava my java statements inside
the jsp file. I just want the jsp file have a command
in it that would call a java file, tell the java file
to compile and run. All the jsp file would do
(hopefully) is just give commands for a seperate java
file to compile and run. Thanks again for any help!Ok, so this other java file has some entry-point method, like main(), right? So call it...
<%
YourJavaClass.main(appropriateArgumentsGoHere);
%>
or better yet, it's an object you can use:
<%
YourJavaClass x = new YourJavaClass();
x.callSomeMethodHere(withAppropriateArgumentsHere);
x.callAnotherMethodMaybe();
%>
You don't need the jsp file to "compile" this java file, you'd already have compiled it beforehand, and it's class bytecode needs to be in your classpath (on the server side) of course.

How to compile other java files and run them from my own programs?

I'm developing a unit testing tool for AspectJ, which can originally generate the stubs for aspect unit to be tested. All these stubs are java files. After generation of stubs, how can I program the code to compile this unit together with these stubs, i.e. how can I put the functionality of compilation and run, e.g. command "javac *.java" and "java *", into my own code.
Hope you can understand what I mean.
Thank you in advance.

When I use Runtime.getRuntime().exec(command) for executing the AspectJ compile command "ajc", "IOException createProcess error=2" always occurs, while it is ok for Java comiple command "javac".
Why this happens when I use Runtime.getRuntime().exec("ajc Hello.java Test.aj")? Is it the reason that Runtime.exec(String) may not support any command in DOS?
(ajc is the compile command for the java file and aj file.)
Thank you in advance.

.java files compile but cannot execute

Hello,-
I have a small problem in that the compiler can find the .java file (javac javaFile.java), however the execute command (java javaFile) does not work (Exception in thread "main" java.lang.NoClassDefFoundError: javaFile). I'm using Windows Vista and JDK 1.6.0_02. Which one of the environment variables is responsible for file execution?
Thanks beforehand, Vahagn

@ smithberry: Now it executes! Thanks for pointing that out and apologies for not seeing the space before the filename. But how come this is at all necessary? Do I have to run all my java programs with this command from now on, including the JUnit TestCase extensions?

Thank you for your time.
Green

Hello, did you read the answers?
You have to put j2ee.jar or servlet-api.jar in your classpath. Those JAR files are included in the Java EE package somewhere. Remove the QTJava.zip junk from the classpath.
If you don't know what the classpath is and how to set it, read this:
Setting the class path
How Classes are Found
And I'll repeat what the others say: if you are very new to Java, then Java EE will probably be way over your head. First learn the language and the standard API. If you understand that well, start with Java EE. Or do you already know what servlets are, and that you need a servlet container to run them, and how to deploy them etc.?

    Console console = System.console();
    String user = console.readLine("user: ");
    System.out.println(user);
}The compiler errors:
h:\java\MainClass.java:5: cannot resolve symbol
symbol : class Console
location: class MainClass
Console console = System.console();
^
h:\java\MainClass.java:5: cannot resolve symbol
symbol : method console ()
location: class java.lang.System
Console console = System.console();
^
2 errors
Could anyone take a look and shed some lights on this?

I have changed to "import java.io.Console;" but this below errors:
h:\java\MainClass.java:1: cannot resolve symbol
symbol : class Console
location: package io
import java.io.Console;
^
h:\java\MainClass.java:5: cannot resolve symbol
symbol : class Console
location: class MainClass
Console console = System.console();
^
h:\java\MainClass.java:5: cannot resolve symbol
symbol : method console ()
location: class java.lang.System
Console console = System.console();

OAF Java File Location

Hello,
I need to create a customization in iProcurement and for that reason I need to find the java files in the server, I have searched the server and the only files that I have found are the class files, how can obtain the java files or where is their location.
Thanks

Moreover if you want to get the original source code file from oracle, then you would have to raise TAR asking for source Java file.
