Jar文件在项目文件夹外不起作用

Question

My jar file doesn't work outside the project folder, unless i put it in the same directory as the lib folder. When i run the jar from command line i get this:

    C:\Users\Computer>java -jar SG.jar

The same with other "windows", cause my application has many menu itens. I have extracted the jar file, just to check and there's no lib folder there. I believe it should. The jar files needed for hibernate and all others required are all in the lib folder. Can someone help?Thanks.. And here is a link to a similar question:

why doesn't my jar file run outside netbeans? ?

Answer 1

Your problem is that your jar does not includes dependancies that it requires for execution.

Your program requires hibernate jars. You can compile all dependancies with your current jar using maven.

Try this : Build jar with dependancies

Answer 2

Jar file can not contain any other jar files. Some tools like ant, can pack several jars inside one you can take a look on the ant. Another way is directly specify class path to your libraries during running using java -cp instead of java -jar

Answer 3

您可以在运行期间使用java -cp /直接指定所需库的类路径。
