Webqueryopen JavaAgent for retrieving HTML code

Ever wondered how you could create Yahoo stock charts, Yahoo News, or for that matter, screen scrapping any HTML page by just knowing the URL? Here's a Java agent which will do just that.

The following code can copied and pasted into a Java agent as it is. This agent can called using @command([toolsrunmacro]) in the webqueryopen event of a form. For this example, I have used a field called "A" . The field is passed through HTML by highlighting the field and selecting passthru html from the text menu. This is especially helpful in including header and footer to your domino based database from your Company Intranet which are done using non-Notes Web authoring tools.

import lotus.domino.*;
import java.net.*;
import java.io.*;
public class DisplayFooter extends AgentBase {

	public void NotesMain() {

		try {
			Session session = getSession();
			AgentContext agentContext = session.getAgentContext();
Document doc = agentContext.getDocumentContext();
URL url = new URL("myURL");
URLConnection conn = url.openConnection();
InputStream is = conn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);

StringBuffer buffer = new StringBuffer();
int nextChar = 0;

while((nextChar = bis.read()) != -1)
doc.replaceItemValue("B", buffer.toString());

catch(MalformedURLException mal)
catch(IOException ioe)
 catch(Exception e) {
