java – Lotus Notes中的Flying Saucer

2023-08-05 14:10:40

我试图将简单的XHTML文件转换为PDF,并使用Flying Saucer和iText这样做.它在Java中没有问题,但是,当我尝试使用相同的代码创建Lotus Notes代理时,我得到了一个例外,我不确定如何处理.

代码：

import lotus.domino.*;
import java.io.*;
import com.lowagie.text.DocumentException;
import org.xhtmlrenderer.pdf.ITextRenderer; 
import org.xhtmlrenderer.util.XRLog;
import java.util.*;

public class JavaAgent extends AgentBase {

    public void NotesMain() {

      try {
        Session session = getSession();
        AgentContext agentContext = session.getAgentContext();
        String received = agentContext.getDocumentContext().
             getItemValueString("Query_String");
        String[] split;
        split = received.split("&");
        String url = split[1];
        split = url.split("/");
        String outputFile = split[split.length-1];
        String direc = session.getEnvironmentString("Directory", true);
        outputFile = direc + "\\" + outputFile + ".pdf"; 
        OutputStream os = new FileOutputStream(outputFile);
        ITextRenderer renderer = new ITextRenderer();
        renderer.setDocument(url);
        renderer.layout();
        renderer.createPDF(os);
        os.close();
        System.exit(0);

      } catch(Exception e) {
        e.printStackTrace();
      }
   }
}

这产生以下结果：

违规行是

ITextRenderer renderer = new ITextRenderer();

谷歌搜索“access_properties_not_allowed”几乎没有任何内容.

解决方法:

1)Notes / Domino中的代理在代理属性中具有其他安全功能,用于设置代理的安全级别.默认情况下,此设置设置为不允许受限操作(默认设置为“不允许受限操作”).

要使代理程序运行该属性,必须将其设置为以下选项之一：

“允许限制操作”
“允许具有完全管理权限的受限操作”

该属性位于“代理属性”对话框的第二个选项卡(密钥选项卡)上.

2)由于已经解释了“通往yamburg之路”,JVM的安全管理器不允许访问系统的属性,因为安全策略未指定允许此操作.
您必须更改Java虚拟机(JVM)的安全策略才能允许访问系统属性.为此,您可以添加“permission java.security.AllPermission;”行.到Notes / Domino目录中的“/jvm/lib/security/java.policy”文件.

进行更改后,java.policy文件将与此类似：

grant { 
    permission java.security.AllPermission;
    permission java.util.PropertyPermission "java.version", "read";
    permission java.util.PropertyPermission "java.vendor", "read";
    permission java.util.PropertyPermission "java.vendor.url", "read";
    permission java.util.PropertyPermission "java.class.version", "read";
    permission java.util.PropertyPermission "os.name", "read";
        // ... and so on ...
}

重新启动客户端/服务器后,任何需要访问System.getProperties()的Java程序现在都将被授予访问权限.
