谨慎使用java的try catch

看看下面代码有何问题：

	public static String writeFileToRemote(File file) throws Exception {
		PostMethod filePost = new PostMethod(Common.getInstance().getProperty(
				"project/remoteFileServer")
				+ "/attach?action=upload");
		try { 
			Part[] parts = new Part[4];
			parts[0] = new StringPart("FILE_KIND", "2");
			parts[1] = new StringPart("RECORD", "true");
			parts[2] = new StringPart("FILE_KIND", "2");
			parts[3] = new FilePart("FILE_PATH", file.getName(), file);	
			filePost.setRequestEntity(new MultipartRequestEntity(parts,
					filePost.getParams()));
			HttpClient client = new HttpClient();
			// 由于要上传的文件可能比较大,因此在此设置最大的连接超时时间
			client.getHttpConnectionManager().getParams().setConnectionTimeout(
					5000);
			int status = client.executeMethod(filePost);

			String file_path = "";
			if (status == HttpStatus.SC_OK) {
				// 从服务器响应的串中取得fileId
				String res = filePost.getResponseBodyAsString();
				String retFileStr = "retobj.fileId = \"";
				res = res.substring(res.indexOf(retFileStr)
						+ retFileStr.length());
				file_path = res.substring(0, res.indexOf('"'))
						.replace('|', '/');
			}
			file.delete();
			return file_path;
		} catch (Exception e) { 
			e.printStackTrace();
			throw new Exception("写远程文件时出现异常！");
		}
	}

Caused by: java.lang.Exception: 写远程文件时出现异常！
com.age.sale.view.tool.ImportTool.writeFileToRemote(ImportTool.java:112)

因此，应该把try catch去掉，如果要catch，必须把报错信息记录下来！并显示到前台！因为查询日志是很麻烦的一件事情。
