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

偉大似乎解決了此問題..但爲什麼我應該指定這個PATH –

我已經發布了下面的答案:) – Reimeus

只需添加C:\Program Files\Java\jdk1.7.0_06\bin到PATH你的安裝目錄。

原因是批處理文件C:\activiti-5.10\activiti-5.10\apps\h2\h2.start.bat的原始java命令依賴於PATH上的java.exe。

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

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

我有類似的問題。出於某種原因，Java JDK已正確安裝在C：\ Program Files（x86）\ Java 或BUT的路徑中，它被設置爲C：\ Program Files \ Java ...一旦我更正了路徑變量，它就解決了這個問題。

另外，注意如果你有詹金斯和Java使用相同的端口號，這可能會導致一切正常的外觀，你將需要讓他們使用單獨的端口號。要檢查此停止詹金斯是否作爲服務運行，然後重新啓動Tomcat
