How to extract .class files?

Hello,
I have four .class files I need to take a look inside, and manage the files. How may I go about doing this? I am not a programmer so I will not understand code. Is there any free app that works and extracts .class files? I have tried RAR Extractor Free and The Unarchiver, but none worked.
Please help!

Why bother? Just distribute the 3rd-party JAR as it is. All it costs you is a little disk space. Why bother to look inside, understand which classes you do and don't need, repackage, ... repeat every 3rd-party release? repeat for every 3rd-party product?
Just ship it the way they ship it.

How to extract .bin file on mac?

Dear Team,
How to extract .bin file on mac os ? please help me
regards,
kalai

Although the link posted by the other responder shows .bin files to be a copy of RAW CD or DVD data in my experience most .bin files are some type of configuration file mainly used with internet routers and other pieces of PC/Networking equipment.
Just where did this .bin file come from and what is it associated with that you are trying to open on your Mac?
If it is a router configuration file that you downloaded you don't open it on the Mac. You log into your router and go to the update firmware section and browse to that file stored on your Mac hard drive and let the router handle opening and updated the routers firmware.

How to extract .SAR files

Hi All
Can anybody tell me how to extract .SAR files. Is it possible through sapcar.exe, if so how.
Thanks in advance

Hi,
reading the note, I found that it refers to the notes 480180 and 13719 for more information about applying the patch. I can not tell you wether you have to apply this patch or not...
The patch seems to contain a changed SAP Script form due to some legal changes in India - if you need the changes to this form, you'll have to apply it.
Basically - this is what note 13719 says - copy the cofile to /usr/sap/trans/cofiles, the data file to /usr/sap/trans/data, go to STMS, add P6BK252127 to the import queue (open the import queue of your system, go to Extras -> Other Requests -> Add) of your system and import it. Note 13719 says to import from the operating system level by calling tp directly, using STMS should also work.
Best regards,
Elmar.

How to extract jar files into a folder in the local disk and then import?

hai forum,
will any one tell me how should i extract jar files into a location in my project folder and then how to import the class files for further usage?
Thank you .

I will be graeateful if u could explain this a bit.
Do you want to say that i should craete instance of
ZipEntry like this
InputStream is =
jarFile.getInputStream(entry);
File inputFile = new
File("C:\\myclasses.data");
FileInputStream fis=
new FileInputStream(inputFile);No! You need to write the entry using FileOutputStream copying all the bytes of the ZipEntry InputStream to the FileOutputStream.
>
What about adding into a directory?Do i have to
create on dynamically?Yes! You can use File.mkdirs(). For example
File ofile = new File("your directory where you will place the zip entries" + zipEntry.getName());
ofile.getParentFile().mkdirs();

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,

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?

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
