Editing .class files

Hi
I am kind of new to Java etc
I would like to know if it is possible to edit a .class file if you don't have the .java file?
If this is possible do I require any software etc?
Thanks in advance for your help
James

Assuming from the "I am kind of new to Java" part
of the original post that raw-binary-editing is
not an option, try running a decompiler such as
Mocha, http://www.brouhaha.com/~eric/computers/mocha.html
(which is open-source and free :)
Please note that while decompilers do indeed return
java source from the .class files you pass in, the
original variable names are lost and as such, code
can look unstructured and be hard to follow.
However they do what you asked, so have fun :)

Verifying .java and .class files match

I have a bit of a strange situation in a team-working environment where many developers copy code to a production server. None of this code is in a Version Control System and I have been given the task of getting it into one (I've chosen Subversion, but that isnt important)
The problem is, its not as simple as doing a full commit of the production server because developers may have copied edited .class files onto the server, but not copied edited .java (therefore the .java file is not the same as the .class file)
Because the server has hundreds (if not thousands) or java and class files, I cant just decompile each of the class files and manually see if they match the java files, so I'm asking, is there a tool that can verify a java file matches a class file of the same name in terms of version (or if not is there an easier way of doing it than the decompile method)?
Thanks in advance

Years ago I had to do something very much like this...and now I'm trying to recall how we did it (and for that matter whether it worked)...and I'm having trouble recalling. Ah, that's what happens when you read forums out of insomnia.
Of course, you can do a baseline check by just checking the file timestamps. Also instead of decompiling the class files you can try re-compiling the source code, and then generating checksums on both class files to see if they're the same.
You might be able to use BCEL (http://jakarta.apache.org/bcel/) to extract some useful information out of the class files. As I recall I tried this but the data wasn't useful for this kind of project, but maybe I'm misremembering. It's worth looking into.

Java .class files low-level (hex) editing?

Hello, all!
I have a problem:
There is an application (namely a J2ME instant messanger for Nokia mobiles). It is a non-commercial application. But unfortunately, there is a bad bug in the application. It is not even a bug, it is more a feature - but it does not support Russian (cyrillic) characters encoding. Russian characters in all incoming messages are displayed with a kind of hierogliphs.
I wrote to developers (and not only I did - I know at least 3 russian people who also wrote a developer about this) - but unsuccessful. Developer keeps silent.
So what I decided is to fix the bug by myself :) By decompilation, e t.c.
Unfortunally, the midlet is hard obfuscated :( So it took me some hours of reading obfuscated code, and now I see some ways which I must try to solve the problem. I think I must write a code which processes the desired String variables (Despite obfuscation, I can see which Strings to process to obtain effect), and inject this code somewhere to be executed, and from where it could reach the desired Strings.
But the great problem is that obfuscated classes produce a lot of erroneus code, which can not be compiled back. So I decide to reject the decompilation at all, or at least of the big classes (where it is a lot of errors, which I can not correct manually).
In some moments, the application stores the desired Strings in the java.lang.Hashmap. So if I could place my processing code into the Hashmap methods, then I could easily process what I need.
Evidently, I can not edit the real basic java classes. But why not to make the applicaton using my class with identical functionality, instead of java.jang.Hashmap?
My idea now is to edit the .class file of the midlet (yeah, edit with notepad), replacing all the references to "java/lang/Hashmap" or "java.lang.Hasmap" with "java/lang/Fuckmap" and "java.lang.Fuckmap".
So did I (replaced it in norepad).
I read the Sun's documentation about .class file structure, and it seems that nothing is against it. There is no encryption, no checksums, e t.c.
Then I produced "Fuckmap" class this way:
import java.lang.Hashmap;
class Fuckmap extends Hashmap {}
(compiled and preverified it of course)
And placed it into java/lang folder inside the application jar.
I instead of working properly, I get the "Application error - invalid constant pool entry"). What do I do wrong?

2 lexzeus, mlk:
I understood you.
I jave just tried it, and used "jaga/util/Fuckmap" (jaga, not java). But still the same ("Invalid constant pool entry). I tried two times (maybe I could make something wrong?), both times took "clean" jar package, e t.c.
Do you really think jav.alang.Hashmap should help now? I have ony little hope :(

Edit a class file in Eclipse

I am new to Java and Eclipse and Weblogic.
I was give a .war file and told to simply edit a parameter that they thought was in one of the .jsp pages in the war file.
the only occurance of the parameter name "SearchProvider" is in the Search.class file located deep in folders under the WEB-INF folder.
the only way i could even find the parameter "SearchProvider" was with the use of an Effective File Search trial software.
I opened (barely) the Search.class file with windows notepad and its mostly jibberish but I can find the reference to "SearchProvider" in the class file.
I need to change this parameter.
When I import this into eclipse, I get the message there is no source file attached to the class file Search.class.
I added the entire class folder into the library. I tried to change the class source but all I have are just the files in the .war package.
I have tried changing the extension to .jar and this will let me add these files as a project, but I cannot edit this Search.class file no matter what I try.
My basic question is, Am I missing files from the client? Do I need more than just a war file?

Most likely you are searching the wrong place, on an web application the first place to start searching is the web.xml, it is the core configuration file it will tell everything about your application including which other tecnologies are being used, like struts, it is very likely that the answer to your question lies in the web.xml file.

Editing Game's End Titles via .class file

I feel idiotic posting this request, but I'm at a loss as to where else to turn.
I downloaded a game called Gopher Bash from this link -
http://www.javafile.com/games/gopher/gopher.php
I've modified the graphics to make it French Bulldog centered for my website, but I simply can't figure out how to edit the .class file to change the closing credits which say 'Gophers ruined your yard'. I tried simply changing the text where it appeared in the file, but this simply caused the entire thing to not work.
If anyone can stop giggling long enough to take a look at this for me, I'd be very appreciative
ps: I'd happily post the .class file details, but I'm not sure which editor to open it and paste it with. I'm using notepad or dreamweaver to edit it, both of which seem to change it in to nonsense...
Thanks in advance,
Carol
ps: in case this helps to clarify things...I've uploaded it into a folder:

How to edit a ".class" file? Anyone?

I hope someone can help me with this...
Someone gave me a class file to put into my applet. However, I'm wanting to go into the class file and change a few things around. However, I've done just about everything to try to find a way to go into the code of this file to do some changing, and I can't find anything to do it with! I've tried Netbeans and Visual Studio .NET, but it doesn't work. Maybe I'm doing something wrong. Does anyone know how to go into the class file and change it?
thanks soo much..

Dreamweaver Teamplate with Library Item for Navigation/Sidebar not updating editable classes

I have a Dreamweaver Template that contains two Library items. One Library item is my navigation bar, the other is a sidebar that shows different content depending on what page you are on. I'm assigning an editable class "active" to the navigation bar to show you are on a particular page, and also assigning the editable class "active" to the sidebar to reveal a portion of the sidebar with links pertaining to that specific page. The default value for the class is "hidden". So what is happening is when I open a page I have created and "edit" the Library Items in it to edit these classes, it resets resets all the other pages on the site to the default class values. How am I able to use editable classes and Library Items to achieve this kind of functionality? The idea is to only have ONE navigaton bar to update on the site and to only have ONE sidebar item to update. Here is an example of the sidebar and navigation in action so you can see what I'm going for. Notice the green button in the navigation bar (that is a list item with the class "active" which is an editable class in the Library Item, also notice the tan links in the sidebar, that is an unordered list that has an editable class of "active" in the Library Items --- these editable classes reset to their defaults when updating the Library Item on the website).
http://www.brumleve.org/joe/temp/CAP/mission.html

In my understanding, whenever you edit the contents of a library item, it will update all other occurances of this library item on the rest of the site. That's "working as designed" as far as I know, unless you break the link by telling it to not update - which kinda defeats the purpose I think.
But theres another way to do this using template properties, i#ve been using this approach myself a couple of times:
Write your navigation bar in the template (.dwt) file itself, then select the class= of your first menu item and choose .. (names might be off, I am using a non-English copy of DW): "modify > template > make attribute editable" from the main menu. Do so for all your menu items and name these new template properties something like "item_x_class"
You'll end up with something like this in your template source:
<div class="@@(item_1_class)@@">
and a matching
 in the header
Now, on each page, you can set the class within the template properties dialog ("modify > template properties"). If your main menu changes, it won't overwrite your template properties, but still update all pages when you do make a change to the menu.
If you're using multiple templates for your site, consider nesting templates, so the master template already includes your navbar and all subsequent templates will "inherit" changes to the navbar code (sans the editable class property).
Hope this helps.. or at least gives you an idea for further experiments..

No need of commenting your import statement. Whenever there is ambiguity, you can use full class name (with package).
Like,
java.sql.Statement stmt=con.createStatement();
Now there is no ambiguity.

Line number in a *.class file, please help, advanced language guys

dear all,
i use c++ to open a *.class file and try to read line number of code in the file, i have 2 questions:
1. i read line number in a method successfully, but i can not understand the meaning of start_pc, following are one of those data, please explain:
s = start_pc,n = line_number
s , n
0 , 123
8 , 125
23 , 126
29 , 127
34 , 129
38 , 130
2. i can not find where the class's line number are, i.e. class start line and class end line, or field's line number.
does these info exist inside a *.class file?
thx for any light

jdb gets line number of fields from class file, not
source file definitely.I'm not really sure how you tested this, but here's my test, and JDB definitely gets its listing from the source file.
First, I created and compiled class Tester:
public class Tester
    public static void main( String[] argv )
    throws Exception
        Tester x = new Tester();
        System.out.println(x.toString());
    int     x;
    int     y;
    private Tester()
        x = 0;
        y = 1;
}Then, I ran this in JDB. Note lines 16 and 17 in the output from "list":
H:\Workspace>jdb Tester
Initializing jdb ...
stop in Tester.mainDeferring breakpoint Tester.main.
It will be set after the class is loaded.
runrun Tester
Set uncaught java.lang.Throwable
Set deferred uncaught java.lang.Throwable
>
VM Started: Set deferred breakpoint Tester.main
Breakpoint hit: "thread=main", Tester.main(), line=12 bci=0
12            Tester x = new Tester();
main[1] list
8    {
9        public static void main( String[] argv )
10        throws Exception
11        {
12 =>         Tester x = new Tester();
13            System.out.println(x.toString());
14        }
15
16        int     x;
17        int     y;
main[1] quit
Tester@b82368Then I edited the source file. Again, look at lines 16 and 17:
H:\Workspace>jdb Tester
Initializing jdb ...
stop in Tester.mainDeferring breakpoint Tester.main.
It will be set after the class is loaded.
runrun Tester
Set uncaught java.lang.Throwable
Set deferred uncaught java.lang.Throwable
>
VM Started: Set deferred breakpoint Tester.main
Breakpoint hit: "thread=main", Tester.main(), line=12 bci=0
12            Tester x = new Tester();
main[1] list
8    {
9        public static void main( String[] argv )
10        throws Exception
11        {
12 =>         Tester x = new Tester();
13            System.out.println(x.toString());
14        }

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

How do I make a batch file if the .class file uses a foreign package?

I am trying to make an MS-DOS batch file using the bytecode file from the Java source file, called AddFields.java. This program uses the package BreezySwing; which is not standard with the JDK. I had to download it seperately. I will come back to this batch file later.
But first, in order to prove the concept, I created a Java file called Soap.java in JCreator. It is a very simple GUI program that uses the javax.swing package; which does come with the JDK. The JDK is currently stored in the following directory: C:\Program Files\Java\jdk1.6.0_07. I have the PATH environment variable set to the 'bin' folder of the JDK. I believe that it is important that this variable stay this way because C:\Program Files\Java\jdk1.6.0_07\bin is where the file 'java.exe' and 'javac.exe' are stored. Here is my batch file so far for Soap:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java Soap
pause
Before I ran this file, I compiled Soap.java in my IDE and then ran it successfully. Then I moved the .class file to the directory C:\acorn. I put NOTHING ELSE in this folder. then I told the computer where to find the file 'java.exe' which I know is needed for execution of the .class file. I put the above text in Notepad and then saved it as Soap.bat onto my desktop. When I double click on it, the command prompt comes up in a little green box for a few seconds, and then the GUI opens and says "It Works!". Now that I know the concept of batch files, I tried creating another one that used the BreezySwing package.
After I installed my JDK, I installed BreezySwing and TerminalIO which are two foreign packages that make building code much easier. I downloaded the .zip file from Lambert and Osborne called BreezySwingAndTerminalIO.zip. I extracted the files to the 'bin' folder of my JDK. Once I did this, and set the PATH environment variable to the 'bin' folder of my JDK, all BreezySwing and TerminalIO programs that I made worked. Now I wanted to make a batch file from the program AddFields.java. It is a GUI program that imports two packages, the traditional GUI javax.swing package and the foreign package BreezySwing. The user enters two numbers in two DoubleField objects and then selects one of four buttons; one for each arithmetic operation (add, subtract, multiply, or divide). Then the program displays the solution in a third DoubleField object. This program both compiles and runs successfully in JCreator. So, next I moved the .class file from the MyProjects folder that JCreator uses to C:\acorn. I put nothing else in this folder. The file Soap.class was still in there, but I did not think it would matter. Then I created the batch file:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java AddFields
pause
As you can see, it is exactly the same as the one for Soap. I made this file in Notepad and called it AddFields.bat. Upon double clicking on the file, I got this error message from command prompt:
Exception in thread "main" java.lang.NoClassDefFoundError: BreezySwing/GBFrame

... 12 more
Press any key to continue . . .
I know that most of this makes no sense; but that it only means that it cannot find the class BreezySwing or GBFrame (which AddFields extends). Notice, however that it does not give an error for javax.swing. If I change the "set path..." command to anything other than the 'bin' folder of my JDK, I get this error:
'java' is not recognized as an internal or external command,
operable program or batch file.
Press any key to continue . . .
I know this means that the computer cannot find the file 'java.exe' which I believe holds all of the java.x.y.z style packages (native packages); but not BreezySwing or any other foreign packages. Remember, I do not get this error for any of the native Java packages. I decided to compare the java.x.y.z packages with BreezySwing:
I see that all of the native packages are not actually visible in the JDK's bin folder. I think that they are all stored in one of the .exe files in there because there are no .class files in the JDK's bin folder.
However, BreezySwing is different, there is no such file called "BreezySwing.exe"; there are just about 20 .class files all with names like "GBFrame.class", and "GBActionListener.class". As a last effort, I moved all of these .class files directly into the bin folder (they were originally in a seperate folder called BreezySwingAndTerminalIO). This did nothing; even with all of the files in the same folder as java.exe.
So my question is: What do I need to do to get the BreezySwing package recognized on my computer? Is there possibly a download for a file called "BreezySwing.exe" somewhere that would be similar to "java.exe" and contain all of the BreezySwing packages?

There is a lot of detail in your posts. I won't properly quote everything you put (too laborious). Instead I'll just put your words inside quotes (").
"..there are some things about the interface that I do not like."
Like +what?+ This is not a help desk, and I would appreciate you participating in this discussion by providing details of what it is about the 'interface' of webstart that you 'do not like'. They are probably misunderstandings on your part.
"Some of the .jar files I made were so dangerously corrupt, that I had to restart my computer before I could delete them."
Corrupt?! I have never once had the Java tools produce a corrupt Jar. OTOH, the 'cannot delete' problem might relate to the JRE gaining a file lock on the archive at run-time. If the file lock persisted after ending the app., it suggests that the JRE was not properly shut down. This is a bug in the code and should be fixed. Deploying as .class files will only 'hide' the problem (from casual inspection - though the Task Manager should show the orphaned 'java' process).
"I then turned to batch files for their simple structure and portability (I managed to successfully transport a java.util containing batch file from my computer to another). This was what I did:
- I created a folder called Task
- Then I copied three things into this folder: 1. The file "java.exe" from my JDK. 2. The program's .class file (Count.class). and 3. The original batch file.
- Then I moved the folder from a removable disk to the second computer's C drive (C:\Task).
- Last, I changed the code in the batch file...:"
That is the +funniest+ thing I've heard on the forums in the last 72 hours. You say that is easy?! Some points.
- editing batch files is not scalable to 100+ machines, let alone 10000+.
- The fact that Java worked on the target machine was because it was +already installed.+ Dragging the 'java.exe' onto a Windows PC which has no Java will not magically make it 'Java enabled'.
And speaking of Java on the client machine. Webstart has in-built mechanisms to ensure that the end user has the minimum required Java version to run the app. - we can also use the [deployJava.js|http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html#deplToolkit] on the original web page, to check for minimum Java before it puts the link to download/install the app. - if the user does not have the required Java, the script should guide them through installing it.
Those nice features in deployJava.js are available to applets and apps. launched using webstart, but they are not available for (plain) Jar's or loose class files. So if 'ensuring the user has Java' is one of the requirements for your launch, you are barking up the wrong tree by deploying loose class files.
Note also that if you abandon webstart, but have your app. set up to work from a Jar, the installation process would be similar to above (though it would not need a .bat file, or editing it). This basic strategy is one way that I provide [Appleteer (as a downloadable ZIP archive)|http://pscode.org/appleteer/#download]. Though I side-step your part 1 by putting the stuff into a Jar with the path Appleteer/ - when the user expands the ZIP, the parts of the app. are already in the Appleteer directory.
Appleteer is also provided as a webstart launched application (and as an applet). Either of those are 'easier' to use than the downloadable ZIP, but I thought I would provide it in case the end user wants to save it to disk and transport the app. to a machine with no internet connection, but with Java (why they would be testing applets on a PC with no internet connection, I am not sure - but the option is there).
"I know that .jar and .exe files are out because I always get errors and I do not like their interfaces. "
What on earth are you talking about? Once the app. is on-screen, the end user would not be able to distinguish between
1) A Jar launched using a manifest.
2) A Jar launched using webstart.
3) Loose class files.
Your fixation on .bat files sounds much like the adage that 'If the only tool you have is a hammer, every job starts to look like a nail'.
Get over them, will you? +Using .bat files is not a practical way to provide a Java app. to the end user+ (and launching an app. from a .bat looks quite crappy and 'second hand' to +this+ user).
Edit 1:
The instructions for running Appleteer as a Jar are further up the page, in the [Running Appleteer: Application|http://pscode.org/appleteer/#application] section.

I am trying to do a silent install of a program I built using LabVIEW 8.5. I also need to call an exe after the installation, so I am using the "run executable after installation" option on the Advanced tab of the installer. I then pass the following command lines to the setup.exe:
/qb /acceptlicenses yes /r
This installs the LabVIEW program successfully, but does not then run the additional exe afterward. If I run the setup.exe normally (with no command line parameters), the additional exe gets run.
Thanks,

This problem is fixed in a future release of LabVIEW. Here's the CAR ID 67549 for tracking purposes.

Unable to edit XLSM files in SharePoint using hyperlink?

Hi All,
Unable to edit .xlsm files using hyperlink, please guide me.
Thanks
Ramanjulu Naidu N

Hi Ramanjulu,
Did this happen to all users?
Did the "Read Only/Edit" dialog pop up when you click the .xlsm Name link from SharePoint 2010?
Could you see the yellow message bar with "Edit Workbook" button when you open the .xlsm file in your Excel Application?
You can check if the following kb article could solve yellow message bar missing problem, set "Browser File Handling" as Permissive for your web application, or update the registry for client Office application.
Also check if the add-on "SharePoint OpenDocuments Class" is enabled in your IE 32-bit browser.

How to include a .class file in a jsp page

hi everyone,
i know the syntax as:
<%@ include file = "filename.class" %>
then at run time the server could not find the class file
if i use,
<%@ page import = "FileName.class" %>
then also the same problem persists
& if i use
<jsp:include page = "Relative address"/>
the problem still remains as it is...
please help me out...i am working on developing an EJB application in which client interacts with server's Stateful session bean through a jsp page...it is necessary for me to include the home interface class file in my jsp page.
P.S. do not suggest me to include the class file in a package & then use
<%@ page import = "packageName.ClassFileName" %>

if i try to make a new package called test & then include my home interface in that package...i need to import University.*to generate the class file of my home interface ; but the class file generation is not taking place as i am getting the error..
"package University does not exist".How can i overcome this problem. The package University, which you are trying to import, must be in the classpath. If you removed it then you will have to add it back.
i have tried my best..but tell me if there's any possible way of including a class file in the jsp page without involving a package.No, there isn't.
If not,then pls help me to generate the class file of my home interface within a package called test.Read the New To Java Tutorial and understand how packages work.

i am assuming that u have a deep knowledge of developing EJB applications.

Error while using .jar file instead of class file.

Hello friends,
I created a java class which are referred and called from other jsp\xml and java files. I compiled this java class and everything is working properly. However, I do not want to use class files but want to use jar files instead. So, I created a jar file of this class file by using the command "jar -cvf jarfilename.jar".I kept the jar file in its respective folder .Also, I removed the class file from its path, just to see that the jar file will work automatically.
Unfortunately, I am getting an error:
java.lang.RuntimeException: Component.createComponent(...) Component class not found: <java class path>. I also tried giving the path of this jar file in the classpath. This also does not seem working.
How to solve this problem?
Thanks,
Ranjith M.V

You probably populated the jar file incorrectly.
A common mistake is to include the path that you had on the classpath, in the jar file.
So a person will have a classpath like this: /foo/
And a class in a package bar, like this:
package bar;So that other classes would include the file like this:
import bar.TheClass;And the class file is on the filesystem like this:
.../foo/bar/TheClass.classThen they'll create the jar file including the foo directory, so if they list the jar's contents, they'll see the above (/foo/bar/TheClass.class). But this is wrong. It should start off so that the jar entries start with the top-level package names (like /bar/TheClass.class).
Maybe you've done that.
