尝试将_C：\ Program Files \ Java \ jdk1.7.0_06 \ bin_添加到您的PATH – Reimeus

伟大似乎解决了此问题..但为什么我应该指定这个PATH –

我已经发布了下面的答案:) – Reimeus

只需添加C:\Program Files\Java\jdk1.7.0_06\bin到PATH你的安装目录。

原因是批处理文件C:\activiti-5.10\activiti-5.10\apps\h2\h2.start.bat的原始java命令依赖于PATH上的java.exe。

ERROR:- 'java' is not recognized as an internal or external command;

这意味着java.exe是不是你PATH的一部分。
添加%JAVA_HOME%\bin您PATH其中JAVA_HOME是对Java

我有类似的问题。出于某种原因，Java JDK已正确安装在C：\ Program Files（x86）\ Java 或BUT的路径中，它被设置为C：\ Program Files \ Java ...一旦我更正了路径变量，它就解决了这个问题。

另外，注意如果你有詹金斯和Java使用相同的端口号，这可能会导致一切正常的外观，你将需要让他们使用单独的端口号。要检查此停止詹金斯是否作为服务运行，然后重新启动Tomcat
