JAVA中的FTDI D2xx驱动程序-(Linux) [英] FTDI D2xx Driver In JAVA - (Linux)
问题描述
让这段代码正常工作真是太糟糕了.我要么在main处得到异常，要么在java.class.path中没有jd2xx
我对Java比较陌生，并且正在使用NetBeans作为我的IDE.如果有人可以偷看代码并告诉我如何在NetBeans中甚至通过命令行运行，我将不胜感激.
当我运行测试应用程序时，我得到以下信息:
>
I am having a terrible time getting this code to work. I either get an exception at main or a jd2xx not in java.class.path
I am relatively new to java and am using NetBeans as my IDE. I would really appreciate it if someone could take a peek at the code and tell me how to get in running in NetBeans or even via command line.
When I run the test application I get this:
>
java -Djava.library.path=".." -cp "../jd2xx.jar;." TestListener
Exception in thread "main" java.lang.NoClassDefFoundError: TestListener
Caused by: java.lang.ClassNotFoundException: TestListener

我已经从两个可以运行的项目中包含了两个版本的jd2xx源代码.我需要的只是jd2xx.jar和jd2xx.dll，它应该可以工作.
在我的项目中(我只是将TestListener.java复制粘贴到NetBeans项目中)，在我的库中包含了jar，IDE可以解析其中的函数，但是当我尝试运行它时，它会在java.class中提供jd2xx.jar .小路.我的jar清单上说:
CODE HERE[] is found at the bottom here
I have included two versions of the jd2xx source code from two project that have it working. All I should need is the jd2xx.jar and jd2xx.dll and it should work.
In my project (I just copy-pasted the TestListener.java into a NetBeans project) have the jar included in my libraries and the IDE can resolve functions inside it but when I try to run it it gives jd2xx.jar not in java.class.path. My jar manifest says:
<pre lang="vb">Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.1
Created-By: 1.6.0_22-b04 (Sun Microsystems Inc.)
Main-Class: Test.Run
Class-Path: lib/jd2xx.jar
X-COMMENT: Main-Class will be added automatically by build
在./dist/他们的下，我的jar和jd2xx.jar在./dist/lib
中
感谢帮助，我敢打赌它只是一个环境变量或混乱的东西...
And under ./dist/ theirs my jar and jd2xx.jar in in ./dist/lib
Help is appreciated, I bet its just an environment variable or something that''s messed up...

检查jd2xx.jar(无论是什么！?)是否包含在构建过程中.如果它是本地Java项目，则应检查项目属性.
Check if the jd2xx.jar (what ever that is!?) is included in the build process. If it''s a native Java project you should check the project properties.
