Converting .class to .java file

Hi,
I need a tool which converts class - files into java -files.
Does anybody know something about this ?
Where can I find those tools ?

The JAD decompiler is excellent for this task. You can get a free GUI using this compiler from http://www.reflectonus.pwp.blueyonder.co.uk/download.htm. It's called FrontEnd.

Converted WSDL into .java-files - and now?

I should implement a client for an existing web service. All I have is a .wsdl-file of the web service to call.
Therefore I used the eclipse's functionality to convert .wsdl into .java files, which generated some files for me, for example:
- interface XXX extending java.rmi.Remote
- interface XXXService extends javax.xml.rpc.Service
- class XXXProxy implements XXX
- class XXXServiceLocator extends org.apache.axis.client.Service
- class XXXSoapBindingStub extends org.apache.axis.client.Stub implements XXX
- class XXXRfcException extends org.apache.axis.AxisFault implements java.io.Serializable
- class XXXRfcExceptions implements java.io.Serializable
My question... what to do now? How can I get the service and call its functionality?
Your help is really, REALLY appreciated...

Hi,
Write client application like below.
public class Client{
public static void main(String [] args) throws Exception {
// Make a service
XXXService service = new XXXServiceLocator();
// Now use the service to get a stub which implements the SDI.
AddressBook port = service.getAddressBook();
// Make the actual call
Address address = new Address(...);
port.addEntry("Russell Butek", address);
Thanks&Regards,
M.Kumaraswamy.

Convert .class to .java (without de compiler)

folks.. i want to write my own program to convert a .class file to .java file. Now i know that there are various programs (e-g DJ Java Decompiler etc) but i want to write my own. Can you plz suggest any guide lines for that ..? how to start off? any idea?

georgemc wrote:
Seriously, anything that turns a class file back into source code is, by definition, a decompiler.
If you're thinking of writing your own, forget it.
This is a classic case of "if you have to ask where to start, you don't have the skills to do it". No, reallyI agree.

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.

Why only 1 public class in java file

In any java file, why do we have only one public class whose name is same as the java file name?

Jasmit1986 wrote:
Thanx for the link db. But in the link it is explained why we have the name of the java file same as the class name.
My doubt is that why can't we have more than one public class in a java fileTo keep things simple and less confusing. There's really no good reason to have multiple public classes in one file, so this just enforces the "best practices" idea.

How to covert .class to .java

Hello All Programmers,
I have some .class files. I missed .java files, I want to convert .class to .java files.
Plz help me how to convert .class to .java file.
Thanks
Santosh

but do make sure you're legally allowed to decompile those classes.
If you are allowed to look at the source, most authors will provide you with it.
If not, you may be guilty of a crime if you do decompile, and at the very least are guilty of breach of contract with your supplier.

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.

Matisse Compiler ...convert xml files into java files.....

We have a matisse compiler which reads the *.xml files and converts this into *.java files. Do we have a plugin
for this compiler which can by used with MyEclipse or Eclipse.

Does anybody know how to convert x.class file back to a x.java file.As Dr.Clap said, that's decompiling.
Or in other terms, extract .java files from a jarfile??That isn't quite the same thing. You can decompile a .class that's in a jar, but a .class file doesn't have to be in a jar and a file in a jar isn't necessarily a .class.

Why is the name of java file is same as public class?

hello friends
why we need to assign same name to .java file as the name of public class in .java file? while its not necessary for the class having no modifier?
