Question

我正在处理一些遗留代码。试图通过Jython在我们的代码中运行python脚本，我得到一个UnsatisfiedLinkError。我试图使用“-D”选项来设置java.class.path选项，但它似乎无法解决问题。对于以下示例，Durandal.jar

下可以使用C:\scm\main\core\isidurandal\durandal\build

"C:\Program Files\Java\jdk1.6.0_31\bin\java.exe" -Xint "-Dpython.path=c:\scm\main\core\isidurandal\durandal\scripts\lib" "-Dpython.home=c:\bin\jython2.5.2" "-Djava.library.path=c:\scm\main\core\isidurandal\durandal\build" -classpath "c:\bin\jython2.5.2\jython.jar;c:\scm\main\core\isidurandal\durandal\build\durandal.jar;c:\scm\main\core\isidurandal\japanese\build\durandalJapanese.jar;c:\scm\main\core\isidurandal\biometrics\build\MtiBiometrics.jar" org.python.util.jython  tools\alignSequences.py

我的理解是，当一个人试图访问不在类路径中的库时，通常会发生这个错误，但我想我已经在命令行上正确设置了它。再说一次，我对Jython还不是很熟悉（对Java或Python不太熟悉），所以我有点在海上。

编辑：看起来这可能是尝试在64位Java下运行32位DLL的问题。如果情况确实如此，我会修改我的问题。

Answer 1

事实上，答案是，它是一个32位DLL，我试图用64位Java运行它。不是非常直观的错误消息......

无法为Jython设置java.library.path
