阅读更多关于 How would one create a custom JVM launcher?

问题 There has been a history of " how to launch an application without a main method " questions, most stating something along the lines of " you can't ".

I found this answer linking us to where we can learn about creating our own JVM

问题 I'm running a java application that we distribute as a server-side system. I'm trying to write a launcher ("write" is somewhat of an overstatement here, I'm basically just copying the Java.exe file so that we can get the desired name in the process explorer of windows). This exe is in our bin/ directory of our application file tree. Now, we also have a jre/ directory in our file tree, which is where Java.exe actually resides (we ship our product with the Java environment). When I use Java.exe
