我不知道如何从命令行调用Java oscar3类方法stringToString

Question

I'm trying to call a Java class method from the command line but the for the life of me can't figure out the syntax. The method is stringToString found in this class http://apidoc.ch.cam.ac.uk/oscar3/apidocs/uk/ac/cam/ch/wwmm/oscar3/Oscar3.html

What I have tried:

java -Xmx512m -classpath .:oscar3-a5:lib/oscar3-a5.jar uk.ac.cam.ch.wwmm.oscar3.Oscar3 stringToString "test"

java -Xmx512m -classpath .:oscar3-a5:lib/oscar3-a5.jar uk.ac.cam.ch.wwmm.oscar3 Oscar3(stringToString "test)

java -classpath .:oscar3-a5.jar:lib/uk.ac.cam.ch.wwmm.oscar3.Oscar3 stringToString "test"

It complains like this:

Exception in thread "main" java.lang.NoClassDefFoundError: uk/ac/cam/ch/wwmm/oscar3/Oscar3
Caused by: java.lang.ClassNotFoundException: uk.ac.cam.ch.wwmm.oscar3.Oscar3
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)

at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

I have also looked at this ( Java: how to import a jar file from command line ) for a solution but clearly I'm too retarded to see the obvious. If anyone knows the correct syntax for this any help would be great.

Answer 1

You are very close! I think you want the following:

java -Xmx512m -cp oscar3-a5/oscar3-a5.jar uk.ac.cam.ch.wwmm.oscar3.Oscar3 stringToString test

Alternatively if your current working directory ( pwd ) is the same directory that oscar3-a5.jar resides in, then:

java -Xmx512m -cp ./oscar3-a5.jar uk.ac.cam.ch.wwmm.oscar3.Oscar3 stringToString test

(I've assumed you're running on *nix - if you're running on Windows replace the / with \\ )
