Servlets are server-side Java applications, as opposed to client-side applets or standalone applications. While servlets are compatible with many different types of servers, typically they are used in web servers, as a replacement for CGI scripts or Active-Server Pages (ASP). Java servlets offer many advantages over other forms of server-side processing.

Gamelan's TechFocus recently published a two-part introductory tutorial on servlets, which I can highly recommend. For more information see http://www.gamelan.com/journal/techworkshop/ I also highly recommend the book, Developing Java Servlets, by James Goodwill. The publisher is Sams, and the ISBN is 0672316005.

To setup servlet, you need to configure servlet into the file web.xml which needs to be placed in /var/www/html/WEB-INF directory. By default all the logging activity will be placed within the /var/log/ directory of your application. If a telnet shell is enabled on your account then 'tailing' the logs can provide a powerful tool in debugging your web application. Viewing the logs is recommended when you suspect that errors are occurring during the loading/reloading of your web application.

Refactoring J2EE components to delegate functionality to other objects that don't have to be run in a J2EE container will improve the design and testability of the software. Cactus is an open source JUnit extension that can be used to test J2EE components in their natural environment.

JSP pages are compiled into servlets, so theoretically you could write servlets to support your web-based applications. However, JSP technology was designed to simplify the process of creating pages by separating web presentation from web content. In many applications, the response sent to the client is a combination of template data and dynamically-generated data. In this situation, it is much easier to work with JSP pages than to do everything with servlets.

Hi..Sir, I want to create a prog. using jdbc,servlets.i.e. when i enter username,password from html that username,password stored in database using servlets. Please be forward.thank you. in web.xml ,we have init-param tag in that we will mention param name and param value ,in b/w the tags strings are written and the are accessed thru servletconfig.getparameter,but while using struts in web.

We do not currently support JSP pages as they can be resource hungry and are not viable in a shared hosting environment. We usually recommend that customers wanting to use Java servlets go on their own dedicated server for enhanced reliability and security for their Java environment. You can request a dedicated quote here.

Yes. By starting OC4J using a JVM executing in debug mode it is possible to remotely debug Servlet code as it executes. To debug applications running on OC4J you must supply the standard JVM debug properties when starting the JVM. java -classic -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000 -jar orion.

We currently provide a Unix-only hosting solution. Due to technological limitations these technologies are restricted to Windows platforms only and are not supported by our servers. We do however support many popular alternatives to the above such as MySQL, PHP, Perl and many others.

For developing servlets, just make sure that the JAR file containing javax.servlet.* is in your CLASSPATH, and use your normal JAVAC to compile servlet. Incase of Tomcat 4.x, you must set classpath to tomcat/common/lib/servlet.jar. Incase of Tomcat 5.x, you must set classpath to tomcat/common/lib/servlet-api.jar Note: Please check the documentation of the Server you are using for exact location and .jar file name.

JSP is not supported at this time. Please put a request for it to be installed if you need it for a small fee.

Yes, just compile as you would any java class. If you are getting class not found then you will need add one or more classpaths. To add the classpaths use the browse button in the Standard Classpath or Custom Classpath dialog to select the jar or zip file containing the needed classes. For class files not in a jar or zip archive Java will find the files given a directory classpath. Check the parameters for your applet or object tag.

Author: Govind Seshadri (http://www.jguru.com/guru/viewbio.jsp?EID=14) Question originally posed by Peter Tsang (http://www.jguru.com/guru/viewbio.jsp?EID=83305 Where you place the beans and servlets depends on which "application" it belongs to. Assuming that you are running your JSP pages under the default "examples" application, you should place your servlets under the path Both these paths are placed within CLASSPATH by Tomcat's startup script file.

Author: Alex Chaffee (http://www.jguru.com/guru/viewbio.jsp?EID=3) Question originally posed by vivek tawde (http://www.jguru.com/guru/viewbio.jsp?EID=133324 There are many products which support servlets on Linux. Most of them operate either in a standalone mode (acting as both web server and servlet engine) or as a back-end servlet engine plugging in to an existing web server (like Apache). See the individual products' web sites and README files for installation instructions.

Latest Answer: Servlets are used as controllers as it recieves the request from the browser and makes the decision ... In struts, I want to highlight the particuluar row from the database....for ex: some fields is there...Id, Name...etc...I want to print the particulatr which one is acheiving the condition......I want all the results in JSP page but the row(condtion is true)should highlight....thnks hi.

To develop servlets, you need a basic familiarity with Java I/O streams, HTML, and the HyperText-Transfer Protocol (HTTP). You'll also need to download the Java Servlet Development Kit (JSDK) which is freely available from Sun Microsystems. Finally, you'll need a web-server that supports servlets, or a servlet engine which augments your server's capability.

JBuilder doesn't really need of any additional setup for working with Servlets. Just create a new Project and creare a new Web Application. Then when...

My web application uses JavaMail to attach and send a file that the user specifies, but my application can't find the file.
