Launching a jar file

Hello, i have problms with launching a jar file.When i try to launch it using java -jar mmeditor.jar it gives me erorr

c:\SWD\MMEditor>java -jar MMEditor.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lo
gging/LogFactory
at cz.cvut.fjfi.hofman.mmm.model.database.DatabaseMod el.<clinit>(Databas
eModel.java:20)
at cz.cvut.fjfi.hofman.mmm.MappingCreator.<init>(Mapp ingCreator.java:38)
....
missing library can be found here:
Commons Logging - Overview
jar file can be found here:
METAmorphoses: DB to RDF transformation - Browse /MM Mapping Editor/1.0 at SourceForge.net

How can i include missing library to the classpath and launch a jar file?

Hi, you can use embedded help in Java.
java -help

Quote:

---

-cp <class search path of directories and zip/jar files>
-classpath <class search path of directories and zip/jar files>
A : separated list of directories, JAR archives,
and ZIP archives to search for class files.

I have read somewhere that classpath is ignored in java while runing jar files.

i have mmeditor.jar file in
C:\SWD\MMEditor
and needed library's at c:\swd\MMEditor\lib\

so i try to do so:

c:\SWD\MMEditor>java -cp c:\swd\MMEditor\lib\ -jar MMEditor.jar
c:\SWD\MMEditor>java -cp c:\swd\MMEditor\lib\commons-logging-1.1.1.jar -jar MEditor.jar

and still i get error

c:\SWD\MMEditor>java -cp c:\swd\MMEditor\lib\ -jar MMEditor.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lo
gging/LogFactory

.....

Well, I unpack the MMEditor.jar. It has manifest file.

For launcher Jar you need all library, which pointed here.
for example
lib/commons-logging.jar
lib/MMEditor.jar
lib/..
java -jar MMeditor.jar
It is all.

Except they won't be in lib.
That class-path in the manifest doesn't use lib/<jar file name>. It's just the jar file, so they all need to be on the same level as the MMEditor.jar.
