我写了我自己的小http服务器 com.sun.net.httpserver.HttpServer
public void handle(HttpExchange t) throws IOException {
OutputStream os = t.getResponseBody();
os.write(generateResponse(t).getBytes());
os.close();
}
如果我尝试写入输出流并且响应较大，则1024会出现以下异常：
java.io.IOException: insufficient bytes written to stream

有没有一种简单的方法来创建一个新的Wildfly服务器实例.
在JBoss AS5中你所要做的就是创建一个默认或全部的副本并启动jboss:
run.sh -c [New instance name]
没有这样的选择 standalone.sh
我有一个带有页眉和页脚的 XSL-FO 文件。
我为页眉和页脚添加了静态内容，但我希望页脚只显示在最后一页。
我怎样才能做到这一点？

我正在尝试使用 occi 连接到 oracle，但没有成功。
我下载并解压：
sqlplus 可以很好地连接到数据库。
我尝试编译我的代码：
g++ -o target/benefits_select benefits_select.cpp -L/data/etc/oracle/instantclient_11_2 -I/data/etc/oracle/instantclient_11_2/sdk/include -locci
我得到以下结果：

像这样的事情：access_log /var/log/nginx/access.2018.11.07.log main;
有人知道怎么做吗？
