警告:JSF1091:找不到文件动态内容的MIME类型 [英] WARNING: JSF1091: No mime type could be found for file dynamiccontent

问题描述

我在日食下收到以下警告:

I get the following warning under eclipse :

WARNING: JSF1091: No mime type could be found for file dynamiccontent. To resolve this, add a mime-type mapping to the applications web.xml

此错误是我发布图片时引起的

This error is caused when I post a picture

在primefaces作曲家之下:

below primefaces composant :

<p:graphicImage  value="#{bean.image}"/>

Java Bean:

Java Bean :

private StreamedContent image;

// Getter
public StreamedContent getImage() {
    try {
        JFreeChart jfreechart = ChartFactory.createPieChart3D("",
                        createDataset(), true, true, false);

        PiePlot3D plot = (PiePlot3D) jfreechart.getPlot();

        File chartFile = new File("dynamichart");
        ChartUtilities.saveChartAsPNG(chartFile, jfreechart, 375, 300);
        chartImage = new DefaultStreamedContent(new FileInputStream(
                        chartFile), "image/png");
        return chartImage;
    } catch (Exception e) {
        e.printStackTrace();
        return new DefaultStreamedContent();
    }
}

// generate data for image
public static PieDataset createDataset() {
    DefaultPieDataset dataset = new DefaultPieDataset();
    dataset.setValue("A",10);
    dataset.setValue("B", 11);
    dataset.setValue("C", 80);
    dataset.setValue("D", 12);
    return dataset;
}

推荐答案

我找到了一个解决方案.

I found one solution.

使用最新版本的Primefaces(3.5).

by using the latest version of primefaces (3.5).

<dependency>  
    <groupId>org.primefaces</groupId>  
    <artifactId>primefaces</artifactId>  
    <version>3.5</version>  
</dependency> 

但是IHM会有令人不愉快的变化

but there will unpleasant changes in IHM
