If you need this one time only, just insert the records in the table jforum_categories and restart JForum. If you will need it many times, use a library like commons-httpclient and build requests to the respective action in the admin (CategoryAction, method insertSave).

To know which url should be used and which parameters send, take a look in the html form of the file templates/default/admin/category_form.htm

Baiscally, you need to send the following parameters:

:arrow: module = adminCategories
:arrow: action = insertSave
:arrow: category_name = <the name>
:arrow: moderate = 0 or 1 (0 false, 1 true)
:arrow: groups = at least one group id. More than one, repeat the argument (like groups=1&groups=2&groups=3)

Hi,

Following to some code examples on the forum here, I've put together this code to add categories programatically.

package com.realdolmen.jforumconfigurator;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.httpclient.Credentials;
import org.apache.commons.httpclient.HostConfiguration;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.HttpState;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.URI;
import org.apache.commons.httpclient.UsernamePasswordCredentials;
import org.apache.commons.httpclient.auth.AuthScope;
import org.apache.commons.httpclient.methods.PostMethod;

public class ThreadServlet extends HttpServlet {
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

/**
	 * The doGet method of the servlet. <br>
	 * 
	 * This method is called when a form has its tag value method equals to get.

	 * @throws ServletException
	 *             if an error occurred
	 * @throws IOException
	 *             if an error occurred
	 */
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

doPost(request, response);
	}

/**
	 * The doPost method of the servlet. <br>
	 *

	@SuppressWarnings("deprecation")
	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

response.setContentType("text/html");
		String categoryName = request.getParameter("category");
		PrintWriter out = response.getWriter();

String url = "http://localhost:8080/jforum/jforum.page?" +
				"module=adminCategories" +
				"&action=insertSave" +
				"&moderate=0" +
				"&groups=1" +
				"&groups=2" +
				"&groups=3" +
				"&groups=4";

out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
		out.println("<HTML>");
		out.println("  <HEAD><TITLE>A Servlet</TITLE></HEAD>");
		out.println("  <BODY>");
		// Create an instance of HttpClient.
		HttpClient client = new HttpClient();
		client.getParams().setParameter("http.useragent", "My Browser");
		
		HostConfiguration hostconfig = client.getHostConfiguration();
		hostconfig.setHost(new URI("http://localhost:8080", true));

Credentials credentials = new UsernamePasswordCredentials("admin", "adminpw");
	    AuthScope authScope =new AuthScope(hostconfig.getHost(), hostconfig.getPort());
	    HttpState state = client.getState();
	    state.setCredentials(authScope, credentials);
	    
		// Create a method instance.
		PostMethod method = new PostMethod(url);

method.addParameter("category_name", categoryName);
//		method.addParameter("moderate", "0");
//		method.addParameter("groups", "1");
//		method.addParameter("groups", "2");
//		method.addParameter("groups", "3");
//		method.addParameter("groups", "4");
		
		try {
			// Execute the method.		
			int statusCode = client.executeMethod(hostconfig, method);
			
			if (statusCode != HttpStatus.SC_OK) {
				out.println("Method failed: " + method.getStatusLine());
			}

byte[] responseBody = method.getResponseBody();

// Deal with the response.
			// Use caution: ensure correct character encoding and is not binary
			// data
			out.println(new String(responseBody));

} catch (HttpException e) {
			out.println("Fatal protocol violation: " + e.getMessage());
			e.printStackTrace();
		} catch (IOException e) {
			out.println("Fatal transport error: " + e.getMessage());
			e.printStackTrace();
		} finally {
			method.releaseConnection();
		}
		out.println("  </BODY>");
		out.println("</HTML>");
		out.flush();
		out.close();
		
	}

}

I do have a problem. When I execute the method using line 111:

I get statuscode 302. This means the method has been moved or something.

I'm not sure if my above code is correct. I had to add something to authenticate as I'm performing an admin operation. Also don't know if this is the correct way to authenticate in JForum.

Somebody who can help?

When I receive the 203 statuscode, I respond with doing the following:

When I do this I'm being redirected to the login page of JForum.

So I still need to figure out a way to authenticate myself.

This is my current code. Some changes were made:

package com.realdolmen.jforumconfigurator;

import java.io.PrintWriter;

import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.URI;
import org.apache.commons.httpclient.methods.PostMethod;

public class ThreadServlet extends HttpServlet {
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

doPost(request, response);
	}

response.setContentType("text/html");
		String categoryName = request.getParameter("category");
		PrintWriter out = response.getWriter();

//		String loginUrl = "http://localhost:8080/jforum/user/login.page?username=admin&password=adminpw";
		
		String url = "http://localhost:8080/jforum/jforum.page?"
				+ "module=adminCategories" + "&action=insertSave" + "&category_name=" + categoryName
				+ "&moderate=0" + "&groups=1" + "&groups=2" + "&groups=3"
				+ "&groups=4";

out
				.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
		out.println("<HTML>");
		out.println("  <HEAD><TITLE>A Servlet</TITLE></HEAD>");
		out.println("  <BODY>");
		// Create an instance of HttpClient.
		HttpClient client = new HttpClient();
		client.getParams().setParameter("http.useragent", "My Browser");

HostConfiguration hostconfig = client.getHostConfiguration();
		hostconfig.setHost(new URI("http://localhost:8080", true));

// Create a method instance.
		PostMethod method = new PostMethod(url);
		
		try {
			// Execute the method.
			int statusCode = client.executeMethod(hostconfig, method);

if (statusCode != HttpStatus.SC_OK) {
				if (statusCode == HttpStatus.SC_MOVED_TEMPORARILY) {
					response.sendRedirect(url);				
				} else{
					out.println("Method failed: " + method.getStatusLine());
				}
				
			} //else{
//				method = new PostMethod(url);
//				
//				statusCode = client.executeMethod(hostconfig, method);
//			}
			
//			if (statusCode == HttpStatus.SC_MOVED_TEMPORARILY) {

//			}		
			
			byte[] responseBody = method.getResponseBody();

// Deal with the response.

			out.println(new String(responseBody));

}

Yes, of course, and I accept that blame. In fact, i covet that blame. As does this tiny ad:
