解决openmeetings导入文件失败

我下载的是最新openmeetings代码

 服务端(http://openmeetings.googlecode.com/svn/trunk/webapp)

客户端(http://openmeetings.googlecode.com/svn/trunk/openmeetings_lps411)

 

这两个代码在ECLIPSE用SVN CHECK到项目中,运行调试就行了

在演讲里导入文件时经常出现死线程,原因是openmeetings代码有问题

1.先写一个这个类

package org.openmeetings.app.documents;

import java.lang.*;
import java.io.*;
import org.red5.logging.Red5LoggerFactory;
import org.slf4j.Logger;
public class StreamGobbler implements Runnable {
 private static final Logger log = Red5LoggerFactory.getLogger(StreamGobbler.class, "openmeetings");
 String name;
 InputStream is;
 Thread thread;

 public StreamGobbler (String name, InputStream is) {
  this.name = name;
  this.is = is;
 }

 public void start () {
  thread = new Thread (this);
  thread.start ();
 }

 public void run () {
  try {
   InputStreamReader isr = new InputStreamReader (is);
   BufferedReader br = new BufferedReader (isr);

   while (true) {
    String s = br.readLine ();
    if (s == null) break;
    log.debug("[" + name + "] " + s);
   }

   is.close ();

  } catch (Exception ex) {
   log.debug("Problem reading stream " + name + "... :" + ex);
   ex.printStackTrace ();
  }
 }
}

 

2.找到org.openmeetings.app.documents中的GenerateSWF类

把executeScript方法里的类容,修改为

 

static HashMap<String, Object> executeScript(String process, String[] argv) {
  HashMap<String, Object> returnMap = new HashMap<String, Object>();
  returnMap.put("process", process);
  log.debug("process: " + process);
  log.debug("args: " + Arrays.toString(argv));
  try {
   Runtime rt = Runtime.getRuntime();
   returnMap.put("command", Arrays.toString(argv));
   Process p = rt.exec(argv);
   StreamGobbler s1 = new StreamGobbler ("stdin", p.getInputStream ());
   StreamGobbler s2 = new StreamGobbler ("stderr", p.getErrorStream ());
   s1.start ();
   s2.start ();
   int exitVal=p.waitFor();

   
   
   log.debug("exitVal: " + exitVal);
   returnMap.put("exitValue", exitVal);
  } catch (Throwable t) {
   t.printStackTrace();
   returnMap.put("error", t.getMessage());
   returnMap.put("exitValue", -1);
  }
  return returnMap;
 }

 

ok,现在不管是导ppt,word,还是图片都行
