referencing the documentation lucas provided we can see the number of
records/page are provided by
displaytag.properties
(version 1.1)
sort.amount=50
(version 1.2)
pagesize=50
..concerning how to manipulate what you're reading all you have to do is
replace the InputStream with one from DS ...
package org.displaytag.sample.DisplaySourceServlet
protected final void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException,
IOException
{
String jspFile = request.getRequestURI();
// lastIndexOf(".") can't be null, since the servlet is mapped to
".source"
jspFile = jspFile.substring(0, jspFile.lastIndexOf(".")); //$NON-NLS-1$
if (jspFile.lastIndexOf("/") != -1) //$NON-NLS-1$
{
jspFile = jspFile.substring(jspFile.lastIndexOf("/") + 1);
//$NON-NLS-1$
}
// only want to show sample pages, don't play with url!
if (!jspFile.startsWith("example-")) //$NON-NLS-1$
{
throw new ServletException("Invalid file selected: " + jspFile);
//$NON-NLS-1$
}
String fullName = EXAMPLE_FOLDER + jspFile;
// InputStream inputStream =
getServletContext().getResourceAsStream(fullName);
//replace the inputStream logic with a stream obtained from configured
DataSource
//if you are using Oracle you can use oracle.sql.OracleJdbc2SQLInput
readAsciiStream which returns InputStream
readAsciiStream
public InputStream readAsciiStream() throws SQLException
(Return the next attribute in the stream as a stream of ASCII characters.
)
JavaDoc available at
http://www.oracle.com/technology/docs/tech/java/sqlj_jdbc/doc_library/javadoc/oracle.sql.OracleJdbc2SQLInput.html#_top_
and simply use that InputStream to read DataSource contents from
anyone else?
