public Process exec(String command);
public Process exec(String[] cmdArray);
public Process exec(String[] cmdarray, String[] envp, File dir);
public Process exec(String command, String[] envp);
public Process exec(String command, String[] envp, File dir);
public Process exec(String[] cmdArray, String[] envp);

因此，只需选择最好的版本，例如，如果您想移交参数，则选择第四个版本。
要获取运行时实例：

 Runtime rt = Runtime.getRuntime();
 rt.exec("~/myapp");

您还可以自己“构建”流程：
http://www .java-tips.org/java-se-tips/java.util/from-runtime.exec-to-processbuilder.html

或使用

org.eclipse.swt.program.Program

( http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/api/org/eclipse/swt/program/ package-summary.html ）

此类最初旨在使用操作系统相关程序运行文件，例如使用默认浏览器的 HTML。但是它也可以用于运行普通的可执行文件。

为了完整起见，要从 Eclipse 中启动 Java 应用程序，您始终可以遵循本指南：
http://www.eclipse.org/articles/Article-Java -launch/launching-java.html

I think you confuse Eclipse plug-in with Eclipse RCP application. What exactly are you trying to achieve here? Have you developed a plug-in, e.g. a ViewPart to extend your version of the Eclipse IDE, for instance Helios 3.6 for Java developers?

Or have you developed a full stand-alone RCP application, which gives you an executable with a blank application window when starting it up?

Could you please specify what you mean by "my menu"? Do you mean the html based start menu? Or do you mean the normal application menu? In case it is indeed a view extension plug-in, you can always run it from "Window" - "Show View" - "Other" and then select your view. You obviously need to deploy your plug-in first (plugin folder in your eclipse path).

These useful tutorials might help you clear things up:

RCP: http://www.vogella.de/articles/EclipseRCP/article.html

Plug-in: http://www.vogella.de/articles/EclipsePlugIn/article.html

EDIT:

Okay, thank you for clearing that up. I assume (I never did that, though) you have two options then. Since your RCP app, once built, should come with a normal runtime binary, you could either use:

java.lang.Runtime.exec()

( http://download.oracle.com/javase/6/docs/api/java/lang/Runtime.html )

This is the standard Java way to run executables. It comes with six overloaded versions:

public Process exec(String command);
public Process exec(String[] cmdArray);
public Process exec(String[] cmdarray, String[] envp, File dir);
public Process exec(String command, String[] envp);
public Process exec(String command, String[] envp, File dir);
public Process exec(String[] cmdArray, String[] envp);

So just pick what's best, e.g. the fourth if you want to hand over arguments.
To obtain the Runtime instance:

 Runtime rt = Runtime.getRuntime();
 rt.exec("~/myapp");

You could also "build" the process yourself:
http://www.java-tips.org/java-se-tips/java.util/from-runtime.exec-to-processbuilder.html

or use

org.eclipse.swt.program.Program

( http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/api/org/eclipse/swt/program/package-summary.html )

This class is originally intended to run files with the OS associated program, e.g. HTML with the default browser. It can however be used to run normal executables as well.

And just to be complete, to launch Java applications from within Eclipse, you can always follow this guide:
