を日/オラクル1.6 JDKを使用している間に問題は存在しませんが、私は IBMのJDK 1.6.0_26に滞在する必要があります。

ご協力いただければ幸いです。

おかげで、 EHA

Answer 1

それはおそらく2つのJDKの間にフォールバックJAXPの選択に問題があります。 -Djaxp.debug=1でjavaを実行し、ログを見てください。私は現在、これと同じ問題に遭遇したことだし、私のログには、私は私の問題は、OSGiの関連していることをかなり確信している

JAXP: find factoryId =javax.xml.parsers.SAXParserFactory 
JAXP: loaded from fallback value: com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl 
JAXP: created new instance of class com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl using ClassLoader: null
