skopiruj ten error z konzoly sem mozno pomozem

"Vypisuje to nejaky eror" toto fakt milujem. A ako ti mame pomoct ked ten error nevydime?

Dobre, obsah suboru log.err:



Exception in thread "main" java.lang.ClassFormatError: SwingSet2 (unrecognized class file version)

Ake mas distro? Ak (k/x)ubuntu (pripadne hociake ine debianovske distro) tak ti asi bude stacit:



sudo update-java-alternatives -l

sudo update-java-alternatives -s java-6-sun



pravdepodobne pouzivas gcj, miesto sun java.

Moje distro Kubuntu 6.10,



tie prikazy nepomahaju..vypis:



update-java-alternatives: directory does not exist: /usr/lib/jvm/java-6-sun

Vyskusal som aj:



sudo update-java-alternatives -s jre1.6.0_01



//pretoze priecinok /usr/lib/jvm/jre1.6.0_01 existuje,



ale vypis:



file does not exist: /usr/lib/jvm/.jre1.6.0_01.jinfo

Tak asi treba nainstalovat balik java-common: sudo apt-get install java-common



A potom vykonat vyssie spomenute prikazy. Ak to nepomoze tak sa mi ozvi na icq

Takze, aby to malo nejaky zmysel, dokoncim to co bolo zacate:

- problem som vyriesil, chyba bola v zlom nastaveni cesty v subore .bash_profile, system nevedel, ze ma nainstalovanu novu javu, obsah suboru .bash_profile:



# ~/.bash_profile: executed by bash(1) for login shells.

# see /usr/share/doc/bash/examples/startup-files for examples.

# the files are located in the bash-doc package.



# the default umask is set in /etc/login.defs

#umask 022



# include .bashrc if it exists

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi



# set PATH so it includes user's private bin if it exists



export JAVA_HOME="/usr/lib/jvm/jdk1.6.0_01"

export JDK_HOME="${JAVA_HOME}"

export PATH="${JAVA_HOME}/bin {PATH}"
