使用Maven和Jersey / Jackson设置生成的依赖于平台的.war文件？

Question

I am trying to write a little REST service as a Java todolist application. Fortunately it runs on tomcat in my Windows 10 environment. Unfortunately it refuses to run on tomcat in my Linux environment (see details below). I thought the idea of Java is to be platform independant. Where is the catch? What am I doing wrong?

Details of environments

Works on Windows 10 Pro

• apache tomcat 8.5.4
• jvm 1.8.0_101-b13
• architecture amd64

Fails on Linux Ubuntu 14.04 LTS (4.4.0-34-generic) (in virtualbox)

• apache tomcat 8.5.4
• jvm 1.8.0_101-b13
• with architecture amd64

Here are the links to my files. I am sorry for not being able to post it here as marked code (markdown or html). I gave up after 45 Minutes. What a shame. :(

Thank you for your help! :)

Answer 1

I would revalidate your Linux environment. I was able to run your code under both Mac OS/X and Ubuntu 14.04 in both Tomcat 8.0.x and 8.5.4. I used a javax.ws.rs.core.Application configuration as you didn't include your web.xml but other than that it is your code directly. I agree with @Andreas that you've got a bit of a mix of library versions but I don't know why you're running across this. Do you have anything else deployed to the Linux Tomcat? Have you made any modifications to, for example, the "lib" directory under the Tomcat installation?

Answer 2

The pom marks javax.servlet as provided so your app would use the version provided by Tomcat. Based on the Exception Report it appears Tomcat on Linux is using an older version, where the getProperties() method does not exist.

From the docs , the getProperties() method was added in 2.0 so Linux Tomcat is apparently using an older version.
