java - 带有 WorldWind 库的 Jar

Question

大家好!我在 WorldWind 库(它是 NASA 库)方面遇到了一些问题。我在 JetBrains Idea 14 中使用 Java 8 编写应用程序。在 Idea 中，我可以成功编译并运行我的应用程序，但是当我尝试使用 Maven 创建 jar 并运行我的 jar 时 - 我有一个大的堆栈跟踪，但有异常。这里是堆栈跟踪:

    Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /tmp/jogamp_0000/file_cache/jln2853478832317459843/jln6471099643623499225/libgluegen-rt.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

我不明白为什么在 Idea ide 中我可以运行应用程序并且一切都很棒，但我无法从 jar 运行它。我在 Maven 中使用插件创建了 jar:

感谢您的回答和帮助!理想情况下它应该可以在 Windows 和 Linux 上运行:)

Answer 1

通过分析异常中的以下几行，当您拥有 32 位库并且您尝试将其加载到 64 位进程中时，它看起来像是平台依赖性问题。

以下 SO 文件存在 jogl 插件问题。

/tmp/jogamp_0000/file_cache/jln2853478832317459843/jln6471099643623499225/libgluegen-rt.so

解决方案:尝试以下取自 Source 的步骤

Running under 64-bit Linux
    Without installing the AMD64 version of JOGL you will likely see errors like Exception in thread "main" java.lang.UnsatisfiedLinkError: no gluegen-rt in java.library.path or Exception in thread "main" java.lang.UnsatisfiedLinkError: ~/wwj/libgluegen-rt.so: ~/wwj/libgluegen-rt.so: wrong ELF class: ELFCLASS32
    To get it working:
    Download the amd64 version of JOGL http://download.java.net/media/jogl/www/
    Unzip the downloaded file and copy the content of the lib directory to your WWJ directory (e.g. cp jjogl-1.1.1-pre-20070511-linux-amd64/lib/* /path_to_WWJ/)
    Edit run-demo.bash and replace the last line in the file with:
    java -Xmx512m -Dsun.java2d.noddraw=true -Djava.library.path=. -classpath ./src:./classes:./
    worldwind.jar:./jogl.jar:./gluegen-rt.jar $1
    (Note: the only change is the addition of -Djava.library.path=.)
