java“错误无法打开文件” jar

Question

I can't run the class or jar file it gives me the "Error cannot open file".

I'm using the following commands:

javac src/*.java

jar cfe MyJar.jar src.Main src/*.class

java -jar MyJar.jar

Output:

javac src/*.java
jar cfe MyJar.jar src.Main src/*.class
java -jar MyJar.jar
Error cannot open file
C^%    

I'm using linux/ubuntu and java:

java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.5) (6b24-1.11.5-0ubuntu1~12.04.1)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

Content of MANIFEST.MF:

Manifest-Version: 1.0
Created-By: 1.6.0_24 (Sun Microsystems Inc.)
Main-Class: src.Main 

Answer 1

The error was actually output from the FileHandler class I made. I feel kinda ashamed now. I'm going to look into it why it didn't print more than the caught exception. Thank you for taking your time and make me notice.

Answer 2

I'm not convinced the error is actually on the java -jar command. I suspect it's the jar command having a problem finding src.Main . Try jar cfe MyJar.jar src/*.class instead.

Answer 3

I am quite sure the error message should read:

Error: Unable to access jarfile MyJar.jar

In any case, the actual file name would be printed.

hence, I guess it is simply the code in the jar files that prints the error.

An easy test:

jar -jar MyJar.jar "this is so stupid"

Is the output then

Error: cannot open file this is so stupid

If so, you consult your source code.
