我已经尝试使用ApachePOI3.6和ApachePOI-ooxml-3.15版本jars从.pptx读取以下代码。

try{
    InputStream fis = Files.newInputStream(file.toPath());
    XMLSlideShow ppt = new XMLSlideShow(fis);
}

但我得到下面的错误，而建设。

constructor XMLSlideShow in class org.apache.poi.xslf.usermodel.XMLSlideShow cannot be applied to given types;
required: org.apache.poi.xslf.XSLFSlideShow
found: java.io.InputStream
reason: actual argument java.io.InputStream cannot be converted to org.apache.poi.xslf.XSLFSlideShow by method invocation conversion

有人建议怎么办吗？
