使用netbeans時Ubuntu上的Javafx錯誤

Question

當試圖在ubuntu linux上運行基本的javafx應用程序時，出現以下錯誤。使用命令行或netbeans運行應用程序時出現錯誤。

Exception in thread "main" java.lang.RuntimeException: java.lang.UnsatisfiedLinkError: Can't load library: /home/venkat/.m2/repository/com/oracle/javafx/javafx/2.1.0-beta/i386/libglass.so

Answer 1

此異常是由於maven無法在類路徑中找到本機庫而引起的。

Netbeans的

您可以通過將運行配置文件裏面JVM參數解決問題。

-Djava.library.path=/home/venkat/Programs/javafx/2.1.0-beta/rt/lib/i386/

圖片

命令行

如果你試圖運行在命令行應用程序面臨同樣的問題，下面的出口應該可以解決它。上述

export JAVAFX_HOME=/home/venkat/Programs/javafx/2.1.0-beta 

export CLASSPATH=\$JAVAFX_HOME/rt/lib/jfxrt.jar 

export LD_LIBRARY_PATH=/home/venkat/Programs/javafx/2.1.0-beta/rt/lib/i386/ 

前兩個ENV變量固定時JavaFX運行無法找到這被看作一個類路徑問題。
