JSP directly generates HTML files
The Touch version is defined as follows:
News. Template
<HTML>
<Head>
<Title> untitled document </title>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312">
<Link href = "../css.css" rel = stylesheet type = text/CSS>
</Head>
<Body>
<Table width = "500" border = "0" align = "center" cellpadding = "0" cellspacing = "2">
<Tr>
<TD align = "center"> <$ title $> </TD>
</Tr>
<Tr>
<TD align = "center"> author: <$ author $> & nbsp; Release Date: <font color = # ff0000> <$ date $> </font> </TD>
</Tr>
<Tr>
<TD> <$ content $>
</TD>
</Tr>
</Table>
</Body>
</Html>
A class that generates HTML:
Import java. Io .*;
Public class writehtml
{
Public writehtml ()
{
}
Public static void save (string S, string S1, string S2)
Throws writefileexception
{
Try
{
A (S1 );
Fileoutputstream = new fileoutputstream (S1 S2 );
Byte abyte0 [] = S. getbytes ();
Fileoutputstream. Write (abyte0 );

}
Catch (ioexception)
{
Throw new writefileexception ();
}
}
Private Static void a (string S)
{
File file = new file (s );
If (! File. exists ())
File. mkdirs ();
}
}
A class for reading touch versions:
Import java. Io .*;
Public class readtemplates
{
Private Static string _ fldif = NULL;

}
Catch (readtemplateexception)
{
Throw new readtemplateexception ("failed to read template information. ");
}
}

}
Private Static synchronized string a (string S)
Throws readtemplateexception
{
String S1 = NULL;
Try
{
