Shall we begin? What Is A Virtual Machine? Before we get to that, though, we first have to understand what a virtual machine is. In layman’s term, a virtual machine allows your computer to simulate an entirely separate system. This makes it possible to run programs that otherwise wouldn’t be compatible with your system architecture – for instance, Android apps on a Windows PC. When a Java file is executed, it’s run through a version of the Java Virtual Machine before the code is interpreted. “Java Virtual Machine Launcher Could Not Find The Main Class” This means that if there’s a problem with the virtual machine, you won’t even be able to run Java programs until it’s been resolved.

Click System, then Advanced Systems Properties, then Environment Variables.Set the New Variable Name to “_JAVA_OPTIONS” without the quotation marks.Set the value to “ -Xmx512M” without the quotation marks.The digits before the M refer to the maximum amount of RAM allocated to Java. There are a few solutions that users on internet forums LOVE to suggest, but while they mean well, you are highly unlikely to see your problem resolved by: For instance, you could also use “-Xmx1024M” or “-Xmx256M”, if you had more or less memory to spare. Running an anti-malware scan (a virus that only messes with your Java Runtime Environment? For what purpose?).This has nothing to do with Java, whatsoever. While this has the potential to resolve very specific problems, it can have catastrophic effects on your operating system and you’re more likely to break something than fix it.

If the classpath does not exist, or if the classpath does not look similar to this:"C:\Program Files\jdk 1.5.0_6\lib C:\Program Files\Java\jdk 1.5.0_6\bin.Look for "Classpath" under the system Variables. Select the advanced tab and then Environment Variables. Another method to check the classpath: Choose Start | Settings | Control Panel | double-click System. ![]() ", the period represents that the current directory is in the class path. For example, in the output "c:\jdk1.5.0_04. To check the classpath on a Windows XP computer, you can type in " echo %classpath%" under command prompt.This can occur if the system environment variables don't contain a classpath at all. If the Java program you run has a dependency on the system environment variables having a classpath that is set to a specific Java SDK directory the way TextPad does, you will encounter compilation errors if the classpath is not set properly.
