Making exe of java file

I have a java file that contains password to log to embaded system using secure copy. So i do not wann to show that password to any one.
So can i make exe of it or any other way to hide the password.
i do not want to use jar or war because it can be easily broken

I have a java file that contains password to log to
embaded system using secure copy. So i do not wann to
show that password to any one.a native executable won't help that
So can i make exe of it or any other way to hide the
password.what makes you think an executable will do this?
i do not want to use jar or war because it can be
easily brokenjust as easily as an executable. and you can't choose between a jar and a war, you have to use whichever is appropriate for your deployment. if you are developing a web-app, how on earth is your container going to load a windows executable? and this isn't a JSP question, in any way shape or form

Converting a java file to a web service

How can i convert a java file to a web service,And then invoke that service by making my other java file.

You can convert your java file into a WSDL with the WSDL2Java utility in Axis. This will create a definition that will be accessible by potential clients.
To deploy your java class, you can use Axis in a Web Server of your choice (Tomcat, Apache). All you need to do is run the Axis Admin Client for a deploy.wsdd file and point your client to the IP:PORT.
Very straightforward.

Making .exe for a java file

Hello all, i'm much interested in making
a java file to be in .exe form without using any
IDE's available for JAVA .
Is it possible for us to make the .exe form of a
java file to be executed in a machine
which has only JRE AND JVM.

Hi Jayandh,
Please see these forum threads. It will give you some idea.

Making '.exe' file/application using JAVA

Hi,
Is it possible to make an application(an exe file) using just Java, just as we in VB.If yes can you please give some idea how can we do that.
Thanks.....

To make a java application run from a click on an icon
you must create a Jar file as I've explained below:
Create a separate folder and place all the source code programs needed to run the application in it. You just need the ones with the .class extension. You don't need the ones with the .java extension.
Open up 'Notepad' and type in this line:
     Main-Class: your class that has the main method
You don't need the .class extension.
ex. If your main method is in a program called HelloWorld.class
type in :
Main-Class: HelloWorld
Make sure you hit the RETURN key at the end of the line. I forgot to do that which is why I spent four hours trying to get this to work!
Save this as: manifest.mf
and put in the same folder as above. Make sure it doesn't save as manifest.mf.txt
     Open MS-DOS.
CD change to the directory and folder you are in.
Type this in exactly as I have written:
jar cvfm0 myprogram.jar manifest.mf *.class
     This should put a Jar file in your folder. Just click on it and it should work.
Make sure the program doesn't need to take input from a command line, like DOS.
Otherwise it will do nothing. As long as your program creates a frame, window, button or something, it should work.
     To run the Jar file from DOS(for testing purposes) type:
java -jar myprogram.jar
     If you get an error stating that it can't find the main method class(like mine did), right click on the 'myprogram.jar' file that was created,
click on properties, then ZipMagic.
Open the 'manifest.mf' file and make sure
that 'Main-Class: yourprogramname' is in there.
     If you followed these directions you should be able to create an executable java file.
Below I've explained what the commands to create the Jar file mean.
jar: means you are creating a java archive file which acts like a ZIP file
c: means create a new jar file
v: means verbose which tells DOS to show the action it is doing
f: means that the files to choose are going to be typed in by a user(you at the Dos prompt)
m: means to use the manifest file that you specify
0: means that the file won't be compressed
To make a JAR file you only need the cfm letters.

Problem in making exe file for java application

helo,
i tried to make an windows installer packge for my jar file using advance installer. There is one option for including JRE with this package. i included jre package also.otherwise ,the applicaiton will not work in client side,if java is not installed in his system.
But the problem is after i make the setup including JRE ,the size of the file become 26mb. So,it took long time to download the application.
What are the essential jav files we have to include while makes the setup for running the application.I included all the JRE folder itself.
So the size become heavy. Anybody plz help me solve this
regards
jithesh

Hello, I have the same problem, did you solved it?

Want to create and exe file for .java files

Hello all :)
I am making a multi-threaded console application.
It also takes command line parameters from user.
I want to create .exe files out of .java files.
Note:- One class contains main method (in default package) and all other classes are in some specific package
I want to create an exe for the whole application.
The solutions which i get on net is exe4j but i was unable to use it.
Please suggest me to create an windows executable file out of java files.
Thanx in advance

by definition, if you double click on the .exe , you won't pass it parameters
you have to launch a shell, reach the directory where the .exe (or .jar) is stored, and launch the exe directly with parameters, e.g:
myApplication.exe -u user -p password
you can't double click on the exe and say "ok, i give you -u -p!" ; everything has to be done simultaneously if your app is using the "String [] args" arguments of main
if you want to specify parameters after launching the app, you have to grab user input in your main

How to package/inlcude C++ .exe and .dll files in a Java Web Start App?

Hello,
I have a Java Web Start application that runs fine if the application is only 1 .jar file.
But I have a need to also run C++ .exe and .dll file from my Java application.
I wonder if someone could please tell me how to package/include C++ .exe and
.dll files in my Java web start application?
Thank you and Best Regards,
Akino

You need to place the EXE and DLLs inside the jar.
Java cannot execute them from the jar. They have to be extracted (see Class.getResourceAsStream) from the jar and copyied into the target machine file system, perahps to the temp directory. Now you can execute them using Runtime.exec() or ProcessBuilder.start().

How to create java files into windows applications i,e. exe files

I been trying to convert my java files to exe files, but i have been reading a lot of webpages speaking of writing a code in c++ source code,
any easier way to do it.

Add your java compiler to the windows path.
Hie thee to a run terminal! Enter
javac filename.java
then enter
java filename
And your program will work.I believe the OP is rather about creating a windows executable out of his application (jar).
@OP If there is an easier way to do this, i must have missed it. Haven't searched thoroughly though. Gave it up as it looked complicated enough.

*.exe Java File

Hi
I made a java application using JCreator LE which i always need to use and always need to run to get some critical output , so what i need to know is that if i can create an executable java file like in windows( .exe File) which when i click on it will pop up my application instead of always compiling and running it in the JCreator software.

Thanks for the reply , but by the way i've tried to
create an executable jar but the commands specified
to create an executable jar is not running in my
command prompt , they do nothing1) JCreator might be able to do that, too
2) I don't believe they do "nothing". Either they provide the JAR or an error message

How to call a exe or bat file from java program

hi,
i actually want to know that how to call a exe or bat file from program so that i can run them parallely.

Try this :
String strCmd = "myFile.bat";
try
     Runtime rTime = Runtime.getRuntime();
     Process process = rTime.exec(strCmd);
     InputStream p_in = process.getInputStream();
     OutputStream p_out = process.getOutputStream();
     InputStream p_err = process.getErrorStream();
     p_in.close();
     p_out.close();
     p_err.close();
catch(Exception e) {
     throw new Exception("Unable to start, "+strCmd);
}

Calling a method from another Java file.

I think I'm doing this right, but I'm obviously going wrong somewhere.
In order to not have one big long java file, I've created one main one to execute the program, and another to do some of the functions. I'm using eclipse, btw.
In the main file, I have
currentTB = getActiveTB(playerArea);If it works, it should get send the player area variable to the getActiveTB method, and store the value it returns in the currentTB variable, right?
In the other file, I have;
package scenes;
public class sceneIndex {
     private TerrainBlock getActiveTB(String areaCode) {
          TerrainBlock tBlock = new TerrainBlock();
                 **DOES STUFF**
          return tBlock;
}I have it set up so the second file is in the source folder "resources" and the package "scenes." The problem is I'm not calling it properly. I'm missing something simple, I think. The only error I'm getting is;
The method getActiveTB(String) is undefined...
Where am I screwing up?
EDIT: Yeah, I'm a rookie here trying to figure it out on my own. My computer science courses, so far, conveniently all consist of just one big java file. Easier to write, sure, but not very efficient/organized.

Error while compiling java file using J2SE 1.5.0

Dear Sir,
I'm getting the following error while compiling the java file.The code is also given.
package test;
public class TestRowSet {
public TestRowSet() {
"TestRowSet.java": cannot access java.lang.Object,bad class file: D:\Program Files\Java\jdk1.5.0\jre\lib\rt.jar\java\lang\Object.class,class file has wrong version 49.0, should be 48.0,Please remove or make sure it appears in the correct subdirectory of the classpath. at line 4, column 1
Please help me out.
--Suketu Naik.

But I'm compiling within "Borland JBuilder 9.0". I've
set the JDK path of the current project to point to
the path of JDK 1.5.0 . I've also tried to compile at
command prompt with "javac". I'm getting the same
error of "Undefinedclassloader" with long StatckTrace.
I don't know anything about JBuilder either. If you use the command prompt and enter the full path to the 1.5 javac.exe then that will prove whether the issue is using an older javac or not. For example "c:\j2sdk1.5.0_01\bin\javac HelloWorld.java"

Is it necessary to put .java file in 'bin' folder

when ever i am creating a .java file i have to put that in bin folder then only javac compiling the file.
otherwise its not compiling the file.
how can i compile my java file by putting in any folder of mine?
even if i am creating any folder inside the bin folder then also its not compiling my .java file.

when ever i am creating a .java file i have to put
that in bin folder then only javac compiling the
file.That's a huge mistake. You should never do that.
otherwise its not compiling the file.
how can i compile my java file by putting in any
folder of mine?Add the Java /bin directory to your PATH so the operating system can find the javac.exe and java.exe apps.
even if i am creating any folder inside the bin
folder then also its not compiling my .java file.Then you've got a bigger problem. You must have compiler errors that you need to read and fix in your source code.
