使用.bat文件运行.jar文件

Question

HI Guys I Have A jar File Named Column Reader. I am trying to Run it using a .bat file that has the Following Script:

@echo off
java.exe -jar Column Reader.jar parameter

Can Anyone tell me why it is not Running? Because I have Managed t Run Another Jar File Named Nope.jar the same way.

Answer 1

This is because you have a space in the file name. Try instead with:

java.exe -jar "Column Reader.jar" parameter

Or better still, rename your JAR file to column-reader.jar . Generally JAR files are named in all lowercase, often without any spaces in the file names.

Some examples of proper JAR file names:

org.springframework.web.struts-3.1.1.RELEASE.jar
poi-ooxml-schemas.jar
slf4j-api.jar
soap.jar

Answer 2

You need to make sure that the command line knows where java.exe , and Column Reader.jar are. Also, you need to put anything that goes together in quotes, so it would be "Column Reader.jar" . You may need to point directly to the jar like this:

java -jar "C:\\Your\\directory\\Column Reader.jar" parameter

To avoid the quotes you can just make sure the path doesn't contain any spaces. Also, if you want to point to a specific java.exe file you can do:

C:\\Program Files\\Java\\jre7\\bin\\java.exe -jar C:\\Your\\directory\\column-reader.jar parameter

You don't have to be so explicit if your environment variable for java ( JAVA_HOME ) is set and if your .bat file is in the same directory as your .jar
