Java Servlet Filter tutorial example using Eclipse & Tomcat

by · January 8, 2009

[ad name=”AD_INBETWEEN_POST”]Servlet Filters are the latest components that are added in Servlet 2.3 specifications. These filters are used basically for intercepting and modifying requests and response from server.  Consider a scenario where you want to check session from the every users request and if it is valid then only you want to let the user access the page. You can acheive this by checking sessions on all the servlet pages (or JSP pages) which users queries or you can do this by using Filter. Let us create a Servlet Filter that just prints the clients ip address and date time. This is just to log users who are accessing the application. We we use Eclipse for developing our application and Apache Tomcat for deploying and running our application.

Step 1: Create dynamic web project in Eclipse.

Starts eclipse and create a new dynamic web project with name ServletFilterProject. Select Target runtime environment. I have selected Apache Tomcat v6.0, you can select any Tomcat version that you have installed. Click on Finish.

Step 2: Create package & Servlet Filter class.

Create a package for Servlet Filters in your source folder of Project. I have created a package net.viralpatel.servlet.filters. Inside the package, create a Java class file called LogFilter.java.

Step 3: Writting Servlet Filter class code.

Modify the LogFilter class and add following code into it.
package net.viralpatel.servlet.filters;

import java.io.IOException;
import java.util.Date;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;

public class LogFilter implements Filter {

	public void doFilter(ServletRequest req, ServletResponse res,
			FilterChain chain) throws IOException, ServletException {

		HttpServletRequest request = (HttpServletRequest) req;
		
		//Get the IP address of client machine.
		String ipAddress = request.getRemoteAddr();
		
		//Log the IP address and current timestamp.
		System.out.println("IP "+ipAddress + ", Time " 
							+ new Date().toString());
		
		chain.doFilter(req, res);
	}
	public void init(FilterConfig config) throws ServletException {
		
		//Get init parameter
		String testParam = config.getInitParameter("test-param");
		
		//Print the init parameter
		System.out.println("Test Param: " + testParam);
	}
	public void destroy() {
		//add code to release any resource
	}
}

Code language: Java (java)
In this filter example, we have implemented an interface javax.servlet.Filter and override its methods init, doFilter and destroy. The init() method is used to initialize any code that is used by Filter. Also note that, init() method will get an object of FilterConfig which contains different Filter level information as well as init parameters which is passed from Web.xml (Deployment descriptor). The doFilter() method will do the actual logging of information. You can modify this method and add your code which can modify request/session/response, add any attribute in request etc. The destroy() method is called by the container when it wants to garbage collect the filter. This is usually done when filter is not used for long time and server wants to allocate memory for other applications.

Step 4: Create Servlet Filter Mapping in Web.xml

Open web.xml file from WEB-INF directory of your Project and add following entry for filter tag.
<filter>
	<filter-name>LogFilter</filter-name>
	<filter-class>
		net.viralpatel.servlet.filters.LogFilter
	</filter-class>
	<init-param>
		<param-name>test-param</param-name>
		<param-value>This parameter is for testing.</param-value>
	</init-param>
</filter>
<filter-mapping>
	<filter-name>LogFilter</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

Code language: HTML, XML (xml)
In this entry, we have added LogFilter class in Web xml and mapped it with URL /*. Hence any request from client will generated a call to this filter. Also we have passed a parameter test-param. This is just to show how to pass and retrieve a parameter in servlet filter.

Step 5: Execute the web application

We are done with the coding part of Servlet Filter example. Now execute the project by Run -> Run As -> Run on server (shortcut Alt+Shift+X, R). Check the console you will see the output that we print using System.out. Change the code in the way you want your filter to work. Let me know your comments and suggestions. :)

    Uh, for the neophyte, what if after setting up this project, entering the code, etc. the launch (http://localhost:8080/ServletFilterProject/) produces only a 404? (Eclipse 3.3.2, WST 2.0.2)

    Hi Russell,
    I am not sure about the error, but it seems that something is wrong hence your browser is not able to get anything (resource not found!!). Can you try running http://localhost:8080 and check what is coming? Also check if your context root is properly set.

    Thanks, this was quite useful. I think I know what problem Russell was encountering:
    The package is set to \"net.viralpatel.servlet.filters\" but in the mapping it\’s trying to find the class \"net.viralpatel.servlet.filter.LogFilter\". If you go into web.xml and add an s to \"filter\" so that it says \"net.viralpatel.filters.LogFilter\" then you should actually get a printout in the console. Otherwise it\’ll throw class not found exception.

    Remember that a Filter is an interface component, and not a Servlet, so in order for it to render output to the browser, you will want to map it to a Servlet. The reason you will get a requested resource is not available 404, is because there is either no welcome-file-list setup, or you don’t have a servlet mapped to the filter. Viral, this is a great example, but I’m pretty sure you did not post your web.xml in its entirety.

    Hi George, There was a type error in my web.xml. I have updated the code. Here is the change.

    
	        net.viralpatel.servlet.filters.LogFilter

    I have changed net.viralpatel.servlet.filter.LogFilter to net.viralpatel.servlet.filters.LogFilter.

      How does the tomcat servlet initialization code know the classpath for net.viralpatel.servlet.filters.LogFilter? I am getting a class loader error, even thought the class is under web/app/WEB-INF/classes directory.

      Thanks,

    Hi Viral,
    Yes! Silly of me that I was doing Cut n Paste the code. If I was to type I would have noticed the small typo (Missing s in filter(s)).
    Amazing but always true – the devil is in the details…LOL

    Then as Brian wrote on 19 December, 2009, 10:43:
    “Remember that a Filter is an interface component, and not a Servlet, so in order for it to render output to the browser, you will want to map it to a Servlet.” it still has a reason to tgrow a 404.
    But as it prints in the console it’s OK for now.

    I will try writting some code now to build some experience as I am new to Http Sessions and have to learn, so I later come up with more constructive questions..

    Thanks for the quick reply (and the correction to the listing..)

    Hi Viral,
    What a good job u’ve done. I have something to ask you. This example is ok when I run the first time, but when I run the second time, I didn’t get the IP as well as the time. I guess the problem because of there’s nothing in destroy method, and we need to put something there to run example again, is that right? (when I close my eclipse and open again and run the example again, then it’s ok). Thank you very much for your article and look forward to hearing from your answer. Thanks a lot

    if i m including these line in Servlet Filter then it is not catching the parameter
    but, if i m using these
    String str = req.getRemoteAddr();

    then its catching IP address…….these is correct…but wat abut request.getparameter(“firstname”)

    Note: I m not talking abut servlet file……i m talking abut servlet filter.

    Please suggest me sum help soon..

    Very new to all this… I get the 404 error as mentioned. “The requested resource (/ServletFilterProject/WEB-INF/web.xml) is not available.” Does anyone have the web.xml showing how to map the filter to a servlet, or is this not the problem.

    HERE IS MY WEB.XML

    ServletFilterProject

    index.html
    index.htm
    index.jsp
    default.html
    default.htm
    default.jsp

    LogFilter

    com.documentum.servlet.filters.LogFilter

    test-param
    This parameter is for testing.

    LogFilter
    /*

    I’m also using the Helios release of Eclipse

    hi,
    I have one question, is it possible to implement all the client side validations we do with javascript in filters ? Because at times, we do face issues with the javascript.
