How to convert class file

Hi all, I am new in java card development.
This is my environment setting:
@echo off
set JC_HOME=C:\JavaCard\java_card_kit-2_2
set JAVA_HOME=C:\j2sdk14103
set PATH=.;%JC_HOME%\bin;%PATH%
I have created the Wallet applet according to 'Zhiqun Chen" text book and named it WalletApp.java.
I have compiled this file to a class file.
This is where is I saved my file
C:\JavaCard\java_card_kit-2_2\samples\src\com\sun\javacard\samples\WalletApp\WalletApp.java.
But I don't really understand how to convert the class file.
May I know what is this for?
-out EXP JCA CAP
-exportpath
-applet 0xa0:0x0:0x0:0x0:0x62:0x3:0x1:0xc:0x1:0x1
com.sun.javacard.samples.HelloWorld.HelloWorld
com.sun.javacard.samples.HelloWorld
0xa0:0x0:0x0:0x0:0x62:0x3:0x1:0xc:0x1 1.0
must save this in what file?
I tried to type in the command line below (and the result):
C:\JavaCard\java_card_kit-2_2\samples>converter -config scr\com\sun\javacard\sap
les\Wallet\Wallet.opt
error: file scr\com\sun\javacard\saples\Wallet\Wallet.opt could not be found
Usage: converter <options> package_name package_aid major_version.minor_ver
sion
OR
converter -config <filename>
use file for all options and parameters to converter
Where options include:
-classdir <the root directory of the class hierarchy>
set the root directory where the Converter
will look for classes
-i support the 32-bit integer type
-exportpath <list of directories>
list the root directories where the Converter
will look for export files
-exportmap use the token mapping from the pre-defined export
file of the package being converted. The converter
will look for the export file in the exportpath
-applet <AID class_name>
set the applet AID and the class that defines the
install method for the applet
-d <the root directory for output>
-out [CAP] [EXP] [JCA]
tell the Converter to output the CAP file,
and/or the JCA file, and/or the export file
-V, -version print the Converter version string
-v, -verbose enable verbose output
-help print out this message
-nowarn instruct the Converter to not report warning messages
-mask indicate this package is for mask, so restrictions on
native methods are relaxed
-debug enable generation of debugging information
-nobanner suppress all standard output messages
-noverify turn off verification. Verification is default
*********************************************************May I know What is the correct command line to convert the class file and what must I do to before converting the class file?
I saw some article saying we must use JDK1.3, is it a must?
Your solution is highly appreciated.
Thank you!

Hi Ricardo,
I saved the file below as WalletApp.opt in the directory of scr\com\sun\javacard\samples\WalletApp
-out EXP JCA CAP
-exportpath c:\javacard\java_card_kit-2_2\api_export_files

WalletApp 0xa0:0x0:0x0:0x0:0x62:0x3:0x1:0xc:0x2 1.0
But I still have the problem below:
C:\JavaCard\java_card_kit-2_2\samples>converter -config scr\com\sun\javacard\sam

error: file scr\com\sun\javacard\samples\WalletApp\WalletApp.opt could not be fo

May I know What's wrong with my command or file?
Where can I download JDK because what I can find is J2SDK.
Thank you!

How to convert class file into exe

I have made a simple calculator using swing.now i want it to be used as an application from the desktop..How can i do it?..any suggestions?

Now i don't know wat to do next since when i double click the jar.....windows shows the message
Failed to load Main-class manifest attribute from c:\users\raghu\simplecalculator\build\classes\simplecalculator\simplecalci.jar
I am using netbeans and i have JRE 5 as well as JRE 6 installed.
I don't knw wat to do.Netbeans creates the .jar file for you,
Simply right click on the project node in nb and select
clean and buildnext goto the location of the project
Eg:
C:\Documents and Settings\raghu0007\My Documents\NetBeans Projects\SimpleCalculcator\dist\There will usually be 2 files in there, 1 for the Gui parts and the other(.jar) the rest.
These two files must always be together (same directory for the jar file to work)
copy the dist folder to C:\Program Files\, Rename it and create a shortcut to the simplecalci.jar file
If you know the above just take a look at how you modified the MANAFEST file and the file(MF,class...) locations in the .jar
For Windows XP

How to convert .class file to .dll file

hi,
I got a problem, I have to convert my java .class file to .dll file. Microsoft VC++ program will invoke the converted .dll file.
Is there any other possibility.
I was confused.
Cam any body help me. If you are having solution for the can you send to my [email protected] account.
thanks,

No, it is not possible to do what you are suggesting. Yes, you could produce a DLL that wraps the JVM and loads your java class exposing a C and/or C++ callable interface, but that is a lot to go through unless your class is VERY complex. Otherwise, you might want to just create and maintain two implementations.

How to convert class files into java files??

Hey Guys,
I need a little help.
I want to know wheather we can view .class files as .java files or convert the .class to .java files.Is ther any tool or software for doing that.
Or in other words can i see the source code of any .class file..??
Plz do tell me if we can do that or any other way we can do that.
Regds,
Gokul

Sort of. A "decompiler" will take a class file and generate a source code file of source code that could be compiled to get the class file you started out with. However, it won't be the same source code that was originally used to create the class. Most notably, comments will be missing, and variable names will probably be meaningless.
And before you say "java is bad because you can decompile it", note that any language that you can execute you can theoretically decompile.
Also, you can view the raw byte codes. If you're familiar with assembly language, or better yet familar with java bytecodes and the JVM in particular, you can often find out what a particular method does just by viewing the byte codes.

How to convert .class into .jar file

Hi,
How to convert .class into .jar file

jsf_VWP5.5.1 wrote:
Hi,
How to convert .class into .jar fileFrom a command prompt, cd to the location of your .class file(s).
If you want to create a simple jar, use: jar -cf Whatever.jar Whatever.class
If you want to compile all .class files in a directory into a jar, use *.class instead.
Now, I'm going to assume you want to create an executable jar... here's how to do that:
1) Create a blank text file; for this example, lets call it main.txt.
2) In the first line of main.txt, type: Main-class: Whatever ('Whatever' should be the name of the class in your program where the main() method is located)
3) Press enter to go to the next line (someone please correct me if I'm wrong, but if you don't insert the line break/CR after the Main-class: statement, this will not work... in my experience, this is true)
4) Make sure you save this file in the same directory as your .class file(s).
5) Type: jar -cmf Whatever.jar main.txt Whatever.class
...and that's about it. For more information on the usage of the jar command and to understand the switches (such as -cmf), try jar --help.
Hope that helps.

So it seems from reading the COMMAND manual that my first issue is that I used a 16GB SD card, and the manual says it will only recogize up to a 2GB SD card. I did use my MB Air's SD card slot and crated a folder and dragged the music files to it, then to the card. So I am going to get a 2GB card and try that next. Otherwise just stick with the iPOD connected. At least that is 8GB
