如何在sql表中存储一个jsp文件并执行它？

Question

1. First I took a query and tokenized it using stringtokenizer method and stored those tokens in a list.
2. I matched these tokens with a table contents.
3. If there is a match I need to execute the corresponding jsp file of the matched token.

How can we do this in java?

while (st.hasMoreElements()) 
{
    list.add(st.nextElement().toString());
}

for (int i = 0; i < list.size(); i++) 
{
    ResultSet rs = s.executeQuery("select * from rultree");
    while (rs.next()) 
    {
        if (rs.getString("name").equalsIgnoreCase(list.get(i)))
            System.out.println(rs.getString("name"));
    }
}

I retrieved the matched tokens... now I want to retrieve the jsp file of matched token and execute it

JSPs are one of the template engines that you can't easily store in the database. Not that it's right to do it with other template engines, but at least it's possible.

JSPs are compiled to servlets, so they need to be present on the filesystem (unless you run the jsp-to-servlet compiler of the servlet container manually, but that's non-standard). If you want to dynamically load a jsp (still from the filesystem), then simply use:

request.getRequestDispatcher("/" + jspName + ".jsp").forward(request, response)
