matlab deploytool到java包javac报错 [英] matlab deploytool to java package javac error

问题描述

我正在尝试包装我的程序以使用 java.我先尝试了一个简单的hello world"，

I'm trying to wrap a program of mine to work with java. I tried a simple "hello world" first,

-hello world.m-

-hello world.m-

disp('你好世界');

disp('hello world');

我使用了 deploytool 并选择了 java 包.

I used deploytool and selected java package.

到达这一行时:执行命令:"javac -verbose -classpath "C:Program FilesMATLABR2009b oolboxjavabuilderjarjavabuilder.jar" -d "C:UsersshacharDocumentsMATLABdeployTutorialdeployTutorial2src类" "C:UsersshacharDocumentsMATLABdeployTutorialdeployTutorial2srcdeployTutorial2helloworld.java" "C:UsersshacharDocumentsMATLABdeployTutorialdeployTutorial2srcdeployTutorial2DeployTutorial2MCRFactory.java""C:UsersshacharDocumentsMATLABdeployTutorialdeployTutorial2srcdeployTutorial2helloworldRemote.java" "C:UsersshacharDocumentsMATLABdeployTutorialdeployTutorial2srcdeployTutorial2package-info.java""

when it reached this line: Executing command: "javac -verbose -classpath "C:Program FilesMATLABR2009b oolboxjavabuilderjarjavabuilder.jar" -d "C:UsersshacharDocumentsMATLABdeployTutorialdeployTutorial2srcclasses" "C:UsersshacharDocumentsMATLABdeployTutorialdeployTutorial2srcdeployTutorial2helloworld.java" "C:UsersshacharDocumentsMATLABdeployTutorialdeployTutorial2srcdeployTutorial2DeployTutorial2MCRFactory.java" "C:UsersshacharDocumentsMATLABdeployTutorialdeployTutorial2srcdeployTutorial2helloworldRemote.java" "C:UsersshacharDocumentsMATLABdeployTutorialdeployTutorial2srcdeployTutorial2package-info.java""

我收到此错误:'javac' 未被识别为内部或外部命令，可运行的程序或批处理文件.错误:向 javac 发送时发生错误(错误代码 = 1).无法构建可执行文件.

I got this error: 'javac' is not recognized as an internal or external command, operable program or batch file. Error: An error occurred while shelling out to javac (error code = 1). Unable to build executable.

顺便说一句:当我尝试独立应用程序/c/c++ 共享库时，它已成功编译.

btw: when I tried standalone application / c/c++ shared library it has been compiled successfully.

提前致谢

推荐答案

可能是您的机器上没有安装或正确配置 Java SDK.打开系统终端，执行以下两条命令:

Possibly the Java SDK is not installed or properly configured on your machine. Open a system terminal and execute the following two commands:

java -version
javac -version

如果它们都有效，您应该继续使用 MATLAB 帮助中的示例.如果没有安装Java SDK.

If they both work you should proceed with the examples from the MATLAB help. If not install the Java SDK.
