java.lang.NoSuchMethodError: 是什么錯誤啊？

childpp

我用eclipse開發(fā)，在配置文件中調(diào)用/discount/discount.jsp就沒有任何問題，但把Jsp文件名換了就出現(xiàn)這個錯誤
報的異常是
java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclipse/jdt/core/compiler/IProblem;

類里邊沒這個方法

我換個jsp就可以調(diào)到，但同一個jsp換個名字就調(diào)不到。
