FOP 蜡染 NoClassDefFoundError: org/apache/batik/bridge/UserAgent

Question

我不使用maven、pom 或任何东西。我只有简单的测试类进行测试，我只是尝试将 XSL-FO 转换为 PDF，但出现此错误。代码很简单：

package testing;

import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream; 

import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.sax.SAXResult; 

import javax.xml.transform.Result; 
import javax.xml.transform.TransformerFactory; 
import javax.xml.transform.stream.StreamSource; 

import org.apache.fop.apps.Fop; 
import org.apache.fop.apps.FopFactory; 

import org.apache.xmlgraphics.util.MimeConstants;


    public class test {

    public static void main(String[] args) {
        String pth="C:/Temp/";
        FopFactory fopFactory = FopFactory.newInstance(new File(".").toURI());
        TransformerFactory factory = TransformerFactory.newInstance();
        OutputStream out;
        try
        {   
        out = new BufferedOutputStream(new FileOutputStream(new File(pth+"myfile.pdf")));

        InputStream in = new FileInputStream(pth+"everything.fo");

        Source source = null;
        Transformer transformer = factory.newTransformer();
        source = new StreamSource(in);      
        Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, out);
        Result res = new SAXResult(fop.getDefaultHandler());
        transformer.transform(source, res);         
        } catch (Exception e)
        {
            e.printStackTrace();;
        }       
    }
}

这是结果：

这是我的库：

我做错了什么？正如我所说，我不使用 POM、MAVEN 等，只是使用简单的 java 代码进行测试。我知道存在一些依赖关系，但是如果没有 POM，我如何管理这些东西？

这是我的 FO 文件： everything.fo

关于这个问题，我已经使用最新版本的蜡染解决了我的问题。

在 POM.xml 我有这个：

<dependency> 
<groupId>org.apache.xmlgraphics</groupId> 
<artifactId>batik-bridge</artifactId> 
<version>1.11</version> 
</dependency>
