爱普生JavaPOS ADK for linux在使用eclipse和java代码时出现错误。

Question

我有一台爱普生TM-T88V打印机，想用自己的java代码用eclipse打印一张收据。已经安装了Linux的javapos adk，将opEpsonJavaPosbin设置为root.bash_profile，当然还有java。也安装了tmt-cups驱动，并使用PPD文件设置了打印机。但是在进行了这些设置之后，我每次在使用eclipse运行我的java代码时都会得到下面的错误。所有所需的javapos jars都在jrelibext文件夹中，甚至用eclipse将opEpsonJavaPosbin的原生JNI库设置为我的java代码。使用SetupPOS获取jpos.xml，并将其也转储到eclipse中。在运行我的代码时，使用了检查健康测试，得到了和eclipse一样的错误。

我被困在这里很久了，没有任何头绪。任何帮助将是非常感激的。

在 ~.profile 和 ~.bashrc.LD_LIBRARY_PATH=optEpsonJavaPOSbin:$LD_LIBRARY_PATHexport LD_LIBRARY_PATH 后，终于没有了错误。
