Question

我在Windows 8上使用Eclipse运行代码时出现问题。下面的代码在Linux上的Eclipse中运行顺利但在Windows 8中运行不正确。

    package first

    import org.biojava.bio.structure.Atom
    import org.biojava.bio.structure.Structure
    import org.biojava.bio.structure.StructureTools
    import org.biojava.bio.structure.align.StructureAlignment
    import org.biojava.bio.structure.align.StructureAlignmentFactory
    import org.biojava.bio.structure.align.fatcat.FatCatRigid
    import org.biojava.bio.structure.align.fatcat.calc.FatCatParameters
    import org.biojava.bio.structure.align.gui.StructureAlignmentDisplay
    import org.biojava.bio.structure.align.model.AFPChain
    import org.biojava.bio.structure.align.util.AtomCache
    import org.biojava.bio.structure.gui.BiojavaJmol
    import org.biojava.bio.structure.align.gui.jmol.StructureAlignmentJmol

    object Alignment {

      def main(args: Array[String]){

          val name1 = "1YYO.A"
          val name2 = "1YYW.A"
          val cache = new AtomCache()
          val algorithm = StructureAlignmentFactory.getAlgorithm(FatCatRigid.algorithmName)
          val ca1: Array[Atom] = StructureTools.getAtomCAArray(cache.getStructure(name1))
          val ca2: Array[Atom] = StructureTools.getAtomCAArray(cache.getStructure(name2))
          val params: FatCatParameters = new FatCatParameters()
          val afpchain: AFPChain = algorithm.align(ca1, ca2, params)
          afpchain.setName1(name1)
          afpchain.setName2(name2)
          println(afpchain.toFatcat(ca1,ca2))
          StructureAlignmentDisplay.display(afpchain, ca1, ca2)

      }
    }

基本上getStructure方法尝试下载PDB文件但它失败并在下面给出错误。

我尝试重新安装并更新JDK，关闭防火墙，添加-Djava.net.preferIPv4Stack=true但我仍然无法解决问题。任何建议将不胜感激。非常感谢提前！

可能是以下Windows问题：

那个适用于Windows 7，不确定它是否适用于Windows 8。

java.net.SocketException：网络无法访问（Windows 8上的Eclipse）
