Creating non-reverse-engineerable Java programs
(14 answers)
Closed 4 years ago.
I have a spring based workflow system where the java plugins are uploaded and kept in jar format, they are referred and used by the jar file. However, I have seen that jar file is very easy to decompile and it is a security risk.
I tried obfuscation as well. I want to run exe so that it is run at byte code so it is very very hard to reverse engineer.
You could use ProGuard as optimizer and obfuscator.
ProGuard also has a maven plugin that you can use it in the build process.

How can I convert my Java program to an .exe file?
(16 answers)
Closed 2 years ago.
So i just finished a small Java program that I've been working on throughout the week and I want to generate an .exe file of it so I can share with my friends. I'm working on Apache Netbeans 11.3 and JDK 8.
I can successfully generate the .jar file but that's pretty much useless.
If you created a java project, then the "other" computer should have the java runtime installed, in order for the jar to be executed there (java -jar your.jar) otherwise if you really want an .exe use one of the many jar2exe converters found on the almighty internet, such as ja2exe you can download it

Here is background : i'm creating a code generator in java as an api. This creates some macro files. I want to know if there are any tools/API's avialbale from SVN that i can call to place these generated Macro files under a directory in SVN.
basically connect to SVN from a java program. check in the generated file.
There are several libs for accessing svn repositories from java e.g. SVNKit. With such a lib you can perform everything what you know from your svn gui.

The JAR file format provides many benefits.
You can make your Java application runnable via a double-click by packaging it into an executable jar.

Bundling the JRE with a Java application
(2 answers)
Closed 8 years ago.
I have read many threads in stackoverflow but I didn't get the answer.
I used JSmooth and Launch4j but what I want exactly is to get a final .exe file from my JAR application and a JRE so that my windows client won't need to install any JRE (in another way: to get a portable application with its own JVM)
I found that is not possible but why? Does that need the compilation fo the jre with my application source?
I hope my question is clear, any help will be appreciated.
Zip the JRE folder and include it as a resource in your .exe file.
At run time, you'll need to extract that resource to the disk, unzip it and then invoke it using ShellExecute to run your .jar file. The size of your executable will probably be quite huge.
This is your only viable solution.. Otherwise, if it is for windows only, why not just write the whole application in C++? Is there a reason why you need your JRE with the application? Why not let the user install their own JVM?

I have written a java program which uses ojdbc14.jar and the program is working fine until it is in eclipse.when I create an executable jar file the ojdbc14.jar is not getting packaged along with it hence my program is not having the driver to make the required connection with the DB.can someone help me in coming up with the steps to create an executable jar file along with the required drivers.
PS: I am doing all this in eclipse so steps relating to eclipse would be highly appreciated.
If you Export a Runnable Jar File, the dependencies will be packaged within the file.
See: http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Ftasks%2Ftasks-37.htm
Also, you can select how the dependencies will be included/packaged:
