ERROR:- 'java' is not recognized as an internal or external command;
错误：- 'java' 未被识别为内部或外部命令；
This means that java.exeis not part of your PATH.
Add %JAVA_HOME%\binto your PATHwhere JAVA_HOMEis your installation directory for java
这意味着它java.exe不属于您的PATH.
添加%JAVA_HOME%\bin到您的PATH地方JAVA_HOME是java的安装目录

Just add C:\Program Files\Java\jdk1.7.0_06\binto your PATH.
只需添加C:\Program Files\Java\jdk1.7.0_06\bin到您的路径。
The reason is that the batch file C:\activiti-5.10\activiti-5.10\apps\h2\h2.start.bathas a raw javacommand which relies on java.exebeing on the PATH.
原因是批处理文件C:\activiti-5.10\activiti-5.10\apps\h2\h2.start.bat有一个java依赖于java.exePATH的原始命令。

I had a similar issue. For some reason the java JDK was installed correctly on C:\Program Files (x86)\Java BUTin the path it was set to C:\Program Files\Java ... once I corrected the path variable it solved this issue.
我有一个类似的问题。出于某种原因，Java JDK 正确安装在 C:\Program Files (x86)\Java但在它设置为 C:\Program Files\Java 的路径中......一旦我更正了路径变量，它就解决了这个问题。
Also, watch out if you have Jenkins and Java using the same port number this can cause the appearance that everything is ok by you will need to have them use separate port numbers. To check for this stop Jenkins if it is running as a service and then restart Tomcat
另外，请注意是否让 Jenkins 和 Java 使用相同的端口号，这可能会导致一切正常，因为您需要让它们使用单独的端口号。要检查此停止 Jenkins 是否作为服务运行，然后重新启动 Tomcat
