java调用swt.jar包dll文件的加载问题？

调用swt.jar时，报错
Exception in thread "AWT-EventQueue-2" java.lang.UnsatisfiedLinkError: no swt-win32-3347 or swt-win32 in swt.library.path, java.library.path or the jar file
at org.eclipse.swt.internal.Library.loadLibrary(Unknown Source)
at org.eclipse.swt.internal.Library.loadLibrary(Unknown Source)
at org.eclipse.swt.internal.C.(Unknown Source)
at org.eclipse.swt.widgets.Display.(Unknown Source)
最终解决方式发：把swt包中的dll文件，拷贝到电脑jre\bin目录下，解决。
请问，有没有其它的解决方法？
