我已经在同一个问题上停留了一段时间，但我不知道为什么在运行项目时出现以下运行时错误。

我需要通过它的
X3D文件才能显示出来，其中包含viewpoint和imageTexture url标记，这些标记经过测试会导致问题。当我从X3D文件中删除这些标签时，它确实可以工作，但没有期望的输出，因为它似乎已放大并且X3D文件没有纹理。我正在使用的
Jars是gluegen-rt, gluegen-rt-natives-linux-amd64, gluegen-rt-natives-windows-amd64, gluegen-rt-natives-linux-i586, j3d-core-1.3.1, jhall, joal, joal-natives-linux-amd64, joal-natives-windows-amd64, joal-natives-linux-i586, joal-all, joal-all-natives-linux-amd64, joal-all-natives-windows-amd64, joal-all-natives-linux-i586, xj3d.browser_2.1.0-nps, xj3d.cadfilter_2.1.0_nps, xj3d.2.1-3rdparty-nps, xj3d.2.1-nps, xj3d-core, xj3d-runtime, xj3d-script-base。设置VM选项的方法是使用-Xmx450M -Djava.library.path="C:\Users\matt\Documents\NetBeansProjects\jar"，并且我已将包含所有Jars的库添加到项目中。编辑
它仍然无法正常工作
EDIT＃2
导致该问题的两个标签是
<viewpoint centerOfRotation="7 1 0" position='10 0 40' orientation='0 0 0 1'></viewpoint><imageTexture url='"http://somewebsite.com/images/test.jpg"></imageTexture>切记上面的网站不是存储图像的网站，而是遵循相同的格式。编辑＃3
现在
X3D文件中的代码是<viewpoint centerOfRotation="7 1 0" position='10 0 40' orientation='0 0 0 1'></viewpoint><imageTexture url="http://somewebsite.com/images/test.jpg"></imageTexture>而且我仍然遇到视点错误，而且我不知道如何解决
最佳答案
对于第一个标签，错误显然是url属性上的虚假单引号。
对于第二个，您可以尝试对所有属性使用一致的引号，某些解析器可能会因此失败。
在全局范围内，您可以从此处开始:
