我的任务
分享求助：JNA调用dll在运行时不稳定，经常JVM crash，如何解决？
我目前使用JNA技术调用C语言编写的DLL操作读卡器，进行卡片的交互工作，
前台的界面使用了Swing制作了简单的界面，但是在运行期间，
总是因为不知名的原因造成JVM 崩溃了。
按照我的程序实现，点击按钮就会调用一个test方法，但是点击一次就可以正确执行，
或者2次 3次 多次点击就会造成JVM崩溃。
不知道大家谁能够帮助解决一下这个问题。
或者如果这个跨平台调用出错的时候，JVM仍然可以运行。否则
我的工具是需要成千上万次的点击执行的，以目前的这种状态，JVM挂了 就要重启程序。
给工作带来很大的不便。
急切需要大家的帮助！ 谢谢 集思广益。

[Quote=引用 5 楼 jx4245 的回复:]
你把DUMP 文件打开。让CRASH 时生成DUMP 文件。 很可能是你那个C DLL 的问题。
[/Quote]
在报错的日志上看 确实问题都是在调用C的时候执行出现错误，
每次还都是在同一个位置，但是这个出错的dll是windows的dll。
还真是难办。或者大家有没有好的java调用dll的方法或者例子之类的。
谢谢大家了

难道在Linux下叫JNI，在windows下就叫JNA了？ 呵呵 搂主笔误吧？是内存的关系吗？ 用logcat看下报的错吧，也许能知道错在哪。

JNA.......是个啥, 我知道有个JNI
这个有很多资料和例子,在谷老师上找吧, 搜索下 JNI使用 ^_^
