[Question] Error with logfactory

[Johannes]

When I start the application using java -jar dist/build/upm.jar I get the error text appended to the end of this issue. I suspect it is a very simple error on my side, but do not know how to approach it. I have done the following:

• I checked that apache-commons-logging was installed (it was).
• I checked that java itself is installed (it is). I have version java-1.8.0-openjdk
• I am running Fedora 19 (most recent software).

Any pointers as to how to resolve this issue?

Kind regards, Guus Bonnema.

The error I get:

I think the problem is the "Class-Path" given in the upm.jar manifest assumes the dependant jars are in the same directory as upm.jar.

If you're looking to start upm using locally compile classfiles you can use,

ant run

Or alternatively,

java -classpath ./build:./lib/AppleJavaExtensions.jar:./lib/appbundler-1.0ea.jar:./lib/bcprov-jdk14-145.jar:./lib/commons-codec-1.3.jar:./lib/commons-httpclient-3.0.jar:./lib/commons-logging-1.1.jar:./lib/commons-validator-1.4.0.jar:./lib/jarbundler-2.1.0.jar:./lib/javacsv.jar:./lib/junit.jar com._17od.upm.gui.MainWindow

Thank you very much. doing ant run solves the issue! I did get 2 warnings, but I suspect they are not essential as the application loaded and executed fine.

Thanks.

P.S. the warnings were (twice):

warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

Not sure whether I should take action.
