"1.4") HKLM\SOFTWARE\JavaSoft\Java Runtime Environment\\RuntimeLib contains the full path to JVM.DLL (eg. A machine with a properly installed JRE should have the following keys in the Windows registry: HKLM\SOFTWARE\JavaSoft\Java Runtime Environment\CurrentVersion contains the current version of JRE (eg. This typically means the JRE is not installed correctly on the target machine. I am trying to run a NativeJ-generated EXE on a particular machine, but I keep getting ""Unable to locate suitable Java Runtime Environment on this machine." What is wrong? However, if for some reason you only wish to use the class file, you can add a single period "." to the CLASSPATH, in which case NativeJ will look for class files under the same directory as the EXE. You can find more information about creating jar files here. Typically, you should package MyApp.class into a jar file, and add the jar file to the CLASSPATH. How do I add MyApp.class to the CLASSPATH? I am trying to make NativeJ load MyApp.class, but I can't seem to do so. Yes, NativeJ EXE will work seamlessly with your custom DLLs. As long as the final class or jar files can be launched by the JVM, the NativeJ-generated executable will work correctly.ĭoes NativeJ work if my application uses custom DLLs that I call through JNI (Java Native Interface)?

You do not need to rewrite the batch file every time you recompile your application!ĭoes NativeJ work with code obfuscater products on the market? Think of the NativeJ executable as a binary version of your batch file. No, you do not have to as long as the main class file and various project parameters remain the same. If space is a major consideration, you may want to think about providing a link to the JRE and asking the users to download/install the JRE themselves.ĭo I need to regenerate the EXE every time I recompile my Java application? You will still need to bundle the JRE files (about 20MB compressed) with your application. The generated EXE does not include the JRE. Help! The generated EXE does not seem to include the JRE. Think of these as DLLs or COM objects that are included with many native applications. You will still need to include your application class or jar files. No, NativeJ generates a Win32 EXE that will launch your Java application using the JVM. Does NativeJ compile my Java application into native code?
