Software Components Needed to Start Servlet/JSP development

Hi
Can you list what are the software components required to develop Servlets and JSP pages.

To practice with servlets and JSP pages you'll need:
- A server where you'll deploy your servlets and JSPs.
Download Tomcat: http://jakarta.apache.org/tomcat/index.html
- Tutorials for Servlets & JSPs: http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html
- Servlet API to compile your servlets. If using Tomcat look for the servlet.jar
in the installation directory under common/lib. You'll have to include this in your classpath.

Software Components for XI in SLD.

I'm starting with my first project in XI, and I have the following doubts.
The SAP ERP systems are loaded as Technical Systems into the SLD with their products and software components, which are contents of Content Repository of the SLD. If, for example, I have to develop a scenario in XI to integrate my SAP ERP system with a legacy system, if I create a new Software Component version to create the XI design objects I need for the SAP ERP side, should I create and assign a new Product version with this SWCV to my SAP ERP Technical System, or I could use it without doing that, and make the connection with the system directly in the Integration Directory?
If anyone has information or tutorials about best practices for creating Products and Software Components depending on the scenario to develop in XI, that would be a lot of help for me.
Thanks in advance
Sebastian Pereira.

Sebastian,
-->if I create a new Software Component version to create the XI design objects I need for the SAP ERP side, should I create and assign a new Product version with this SWCV to my SAP ERP Technical System, or I could use it without doing that, and make the connection with the system directly in the Integration Directory?
Yep you can ...Software component takes part only in design time...at configuration time You need to import the Business system in Integration Directory..
Configuration time activity:
1. Create Technical and Business systems in SLD( Business system should be associated with this Technical system only)
2. Now import Business System from tool menu item of ID
3. Right lick and Create a scenario in ID
5. Under this scenario you can see the configuration objects you need to configure an create..these objects
PS : Don't forget to activate the objects in ID
Let me know if you want further clarification of thoughts..

Getting started with JSP

Could anyone tell me exactly what you need to start doing JSP? I'm thinking of using it for a college project with MySQL.
What exactly is Tomcat? Do you need Apache as well?
Would it be possible to install everything on my Win98 computer at home, or would I have to use the server at college?
Many thanks for any thoughts!

what questions would I need to ask them?Well, whatever you want to know... ;-)
Would you expect the necessary stuff to be installed
on the host already, or would they let me install
MySQL and whatever else I need? Is it likely to be a
nightmare to set up?I think, when you're doing the shop, you'll have to install those servers. But I'd ask them, if some of the software is already installed and/or if some software is prefered.
Could it turn out more complicated to use Resin than
Tomcat, from this point of view?There's a difference between tomcat and resin: Tomcat is free. Correct me when I'm wrong. This is the license of tomcat:
http://www.apache.org/licenses/LICENSE
Resin is a commercial product, and it's only free for development. And it starts about US$1000...
http://www.caucho.com/sales/index.xtp
From my personal experience it's difficult to install tomcat, but I never really tried... resin was easier, but I'll give tomcat a try again.
The MySQL stuff isn't difficult to install and I think you'll find some good readmes for everything. So if you're on your own to install the software you need, it won't take long if you previously installed some pakets.

Servlet - JSP design and performance (Tomcat)

Hi everybody.
I'm new in Tomcat and servlet/JSP development.
My current design involves only one servlet (does the business logic, JSP page selections) which delegates the requests to several JSP-s (the JSP-s are included with the "jsp:include" tag).
The questions:
1. Has this design some performance drawbacks in contrast with a design in which several servlets are used (some of the included JSP pages will be the same)?
2. How Tomcat resolves concurent requests (if the same servlet is involved or two separate servlets are involved)?
Any response is greatly appreciated.
Thanks.

A few things to keep in mind:
Every JSP is really a Servlet. Behind the scenes, these are compiled into Servlets which are then run. So, you really do have an implementation with more than one Servlet.
Controller Servlet's (one per JVM) are a very popular architecture choice. Struts, Spring and a number of other frameworks use this model. There should not be a difference between running multiple versus a single Servlet, and even if there is, your application undoubtedly has scaling bottlenecks other than this (probably orders of magnitude higher) than worrying about this particular issue.
Tomcat dispatches the request to whatever Servlet satisfies the servlet-mapping that the URL matches. Since Servlet's are designed to be written thread-safe, and since the container will manage those instances, do not worry.- Saish

What software do I need to get started with GIS development

Hello, I'm a Oracle RDBMS specialist but interested in getting into GIS development. I want to set up a local environment and play around with it. Could someone advise me as to what software I need to install/download? Is all of it free?
1.) I'm assumming I need ORACLE with SPATIAL (was looking into 10g) Is this download free?
2.) I also looked into MAP VIEWER as an extension of the Oracle Application Server.
Are these 2 products all I need to get started?
I also read alot about arcGIS? Can this product be downloaded for free or is it a licensed product?
Does anyone have any other suggestions about some software/documentation that may help me get started in this technology.
Thanks,

Hello!!
Actually, you need Oracle Spatial or Oracle Locator. Oracle Locator is free on Oracle Express, and you could start with it. Otherwise, if you want to know more, Oracle Spatial comes with Oracle Enterprise, and Oracle 10g gives you a schema that allow you to store, manage and query spatial data through Oracle functions, etc.
To start using MapViewer, considering that you already have some spatial data stored on the database, you could download the MapViewer kit at http://www.oracle.com/technology/products/spatial/index.html.
You could buy the Pro Oracle Spatial book. It´s very good.
Good Luck!

Best IDE for developing Applets,Servlets,JSP

Hi,
I'm looking for a little bit of advise. I have been developing prototypes using Apache Tomcat. Now I need to go into a full development phase, and I need an IDE to help speedup my work, especially when it comes to debugging applets and servlets. So the following are my questions:
1. What is the best IDE to use in conjunction with Apache Tomcat? Does JBuilder, for example, fit this bill?
2. Outside of Apache, I believe there is for example IBM's Websphere, which includes an IDE and a Servlet/JSP container. Which is the best of these packages?
Thank you for your help.

Why do we use both servlets & jsps in developing an application ?

why do we use both servlets & jsps in developing an application & not only jsps

Hi,
It's a pure question of design : Some like it jsp to jsp and others servlet to jsp. It's up to you to decide and it depends of the complexity of your application.
But the best design is the MVC (servlet and jsp working together) because it helps you separate presentation from logic. It also helps you better maintain you code.
You can have more info in javaworld.com.
Good luck

Need a good charting library (for use in a servlet/jsp environment)

Anyone know of a good charting library for use in a servlet/jsp environment.

Use JFreechart combined with cewolf.
www.object-refinery.com/jfreechart/
To use charts in a jsp page you can use cewolf ( a taglib) based on jfreechart.

Both are free.

Deployment error - Missing class: javax.servlet.jsp.jstl.core.Config

Hi,
We are using JDeveloper 10.1.3.0.4(SU5) on windows for development of ADF application. We need to deploy the developed application onto Oracle Application Server 10g (10.1.3) which is running on Solaris. We are using BC4J, WAR and EAR deployment profiles in jdeveloper to create the .war and .ear files.
If I deploy the generated ear on a standalone OC4J server install on my windows PC, it works fine.
Now when I deploy the generated .ear file onto the Oracle Application Server 10.1.3 through Application Server Control interface and then try to access the jspx pages under our application we are getting following error:
oracle.classloader.util.AnnotatedNoClassDefFoundError: Missing class: javax.servlet.jsp.jstl.core.Config Dependent class: com.sun.faces.application.ViewHandlerImpl Loader: accaweb.web.accaweb:0.0.0 Code-Source: /oracle/app/oracle/product/10gas3/j2ee/home/applications/accaweb/accaweb/WEB-INF/lib/jsf-impl.jar Configuration: WEB-INF/lib/ directory in /oracle/app/oracle/product/10gas3/j2ee/home/applications/accaweb/accaweb/WEB-INF/libThe missing class is available from the following locations: 1. Code-Source: /oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib/jstl.jar (from WEB-INF/lib/ directory in /oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib) This code-source is available in loader default.web.defaultWebApp:0.0.0. at oracle.classloader.PolicyClassLoader.handleClassNotFound (PolicyClassLoader.java:2051) [oracle/app/oracle/product/10gas3/j2ee/home/lib/pcl.jar (from system property java.class.path), by sun.misc.Launcher$AppClassLoader@1482257]
I have confirmed that the .war file inside the .ear file does contain the jstl.jar file under WEB-INF/lib folder. And the jar file does contain the class 'javax.servlet.jsp.jstl.core.Config'
As a workaround, I found that if I copy the jstl.jar file from default-web-app to my application web-inf/lib folder, things start to work fine. ie copy from: '/oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib/jstl.jar'
to: '/oracle/app/oracle/product/10gas3/j2ee/home/applications/accaweb/accaweb/WEB-INF/lib/'
– or –
Another workaround is to add the '/oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib/jstl.jar' file in the classpath for my web application through Application Server Control setting page.
Now both of these workaround needs us to perform additional post deployment steps which should really not be required since the jar files is included in the project.
Has anyone faced this issue? Any pointers in this respect will be a great help.
regards - rutwik

Surprise Surprise !
I just tried deploying the file via uploading it from the Application Server Control UI and it worked fine.
Till now, I was ftp'ing the ear file from my PC to the server on which Oracle AS is running and was telling Application Server Control to pick form that uploaded location.
I am still not clear on why it works with HTTP upload and not via the FTP upload?
cheers - rutwik

What do I need to start a server?

Hello,
I am an interested college student and I would like to make a test application server on my PC to basically just learn the JSP technology and possibly host a personal site on it. I have had a year of Java in high school, however we only really worked on desktop apps. I want to know what specific applications I need that I can download for free from the Sun site to accomplish this task. I have downloaded Java System Application Server Platform Edition 8 and definitely will use Studio Creator. I have used NetBeans in the past (I realize Netbeans is more for desktop apps and the Studio Creator is for web stuff), but it confused me with the amount of features which gives me a strong feeling that I only dabbled in watered down (newbified) techniques in my class (for ex: the use of BreezySwing). I know I could definitely read Documentation for years straight without any problem, but I want to just jump in and do! Any tips on where I can learn more condensed, concept-based info instead of detailed, confusing, long listing?
Thanks in advance,
Shaun

Rather than going with the sun application server, I would recommend you get a hold of Jakarta Tomcat.
It also is free, and is a good place to start with web programming.
With Tomcat you can jump straight into servlet/JSP programming, without worrying about EJB, JMS, javamail... and all the other extra stuff that is part of the J2EE spec.
You can find Tomcat here: http://tomcat.apache.org
Setting it up: http://www.coreservlets.com/Apache-Tomcat-Tutorial/
The Tomcat docs are fairly good. I recommend you read this tutorial on setting up web applications: http://tomcat.apache.org/tomcat-5.5-doc/appdev/index.html

Problem: package javax.servlet.jsp does not exist

I am a novice JSP programmer. My projects that use any javax.servlet classes are not seeing those at all. I am working with a group of folks using Java SE 1.5. (Note: I'm using Windows so the directory separator is "\")
What Used to work:
1. Nearly all my projects were working using Java version 1.6. These projects were developed as examples from Wrox and Apress books about JSP and Struts.
What has changed:
1. I un-installed the version 1.6 of JDK and JRE, as well as tomcat, netbeans, and all the associated libraries/jars.
2. I installed version 1.5 of JDK and JRE, as well as tomcat, netbeans, and all the associated libraries/jars.
3. I updated my JAVA_HOME, CATALINA_HOME, CLASSPATH, and PATH environmental variables. I made sure that the path to servlet-api.jar (in the tomcat common\lib) is included in the classpath.
What is wrong:
1. References to javax.servlet.* are not satisfied--they are flagged in the source code in NetBeans and I get compiler errors with any project containing those references. For example:
... package javax.servlet.jsp does not exist
import javax.servlet.jsp.*;
What I've found:
1. My CATALINA_HOME=C:\Java\Tomcat 5.5
2. My JAVA_HOME=C:\Java\jdk1.5.0_11
3. My CLASSPATH=.;C:\Program Files\QuickTime\QTSystem\QTJava.zip;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib;%JAVA_HOME%\lib\jsp-api.jar;%CATALINA_HOME%\common\lib\servlet-api.jar;C:\Java\logging-log4j-1.2.14\dist\lib\log4j-1.2.14.jar
4. My PATH=c:\wint\BIN;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;%CATALINA_HOME%\bin;C:\MySQL\MySQL Server 5.0\bin;D:\MiKTeX 2.5\miktex\bin;C:\Perl\bin\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\QuickTime\QTSystem\;C:\Program Files\Microsoft SQL Server\80\Tools\Binn\;C:\SFU\Perl\bin\;C:\SFU\common\;C:\Program Files\Lahey-Fujitsu Fortran\v7.1\Bin;C:\Program Files\Lahey-Fujitsu Fortran\v7.1\Win32\Bin
What I need:
1. I need to have some reference to the servlet classes satisfied in my configuration. Any help is appreciated.
thanks
jondr

Oh. I got some over-the-shoulder debug help.
My error was in the classpath specification:
The path: %JAVA_HOME%\lib\jsp-api.jar
Should be: %CATALINA_HOME%\lib\jsp-api.jar
That contains the javax.servlet.jsp.*
Thimk.
