使用JavaAPIForKML寫入KML文件的問題

Question

我試圖從文本文件生成KML文件。 當我嘗試編組內存文件時，出現以下異常。 任何線索？

javax.xml.bind.PropertyException: name: com.sun.xml.bind.namespacePrefixMapper value: de.micromata.opengis.kml.v_2_2_0.Kml$NameSpaceBeautyfier@1cfa4b2

Answer 1

當使用com.sun.xml.bind.namespacePrefixMapper你需要確保你有你的類路徑中JAXB RI（或EclipseLink JAXB (MOXy)上。

JDK包含改名爲JAXB RI的版本，所以你可以嘗試以下屬性包名稱，而不是：

com.sun.xml.internal.bind.namespacePrefixMapper
