我得到了一个java.lang.OutOfMemoryError: Java heap space，我不知道如何避免它。我正在写出我认为基本上是套接字缓冲区的内容。我认为是javax.servlet.jsp.JspWriter。
但是，当我尝试编写非常大的 HTML 文件（约 700,000 行）时，我得到一个java.lang.OutOfMemoryError: Java heap space. 我很困惑为什么框架不只是刷新到套接字。(Marsha, Marsha, Marsha) 开个玩笑，我可以让它刷新到套接字，而不是仅仅增加缓冲区。
我正在使用 JSF 1.1。
注意，我确实尝试添加这个 web.xml：
<context-param>
<param-name>facelets.BUFFER_SIZE</param-name>
<param-value>500000</param-value>
</context-param>
它似乎没有改变任何东西。
这是我的代码示例：
<html>
<f:view>
<head>
<title>Test</title>
</head>
<body id="page_body"
<h:form id="form">
<%
String s;
for (int i = 0; i < rowCount; i++) {
s = data.get(i);
out.println(s);
//flush after on every thousandths row.
//if(i%1000==1)
// out.flush();
} // for loop
%>
</h:form>
</body>
</f:view>
</html>
这是我得到的例外：

顺便说一句，BalusC，如果你在那里，请帮忙。没压力，呵呵。您回答了大约一半的 JSF 问题。
