JWSDP Tutorial - Servlet Example

I am trying to run the bookstore example in the Servlet section of the JWSDP on Red Hat 7.3.I am also getting confused over ANT and the Tomcat Manager.
I need to build the bookstore example and the instructions read: (for those who know the tutorial)
1. In a terminal window, go to /docs/tutorial/examples/web/bookstore1
2. Run ant build - The build target will spawn any necessary compilations and copy files to the docs/tutorial/examples/web/bookstore1/build directory.
3. Make sure Tomcat is started.
4. Run ant install - The install target notifies Tomcat that the new context is available.
5. Start the Pointbase database server and populate the database if you have not done so already
6. Open the bookstore URL http://localhost:8080/bookstore1/enter
On the command line I can run ANT BUILD fine, but ANT INSTALL fails. (It also fails in Tomcat Manager...but not sure whether I can use this instead of ANT INSTALL?)
I know this is sketchy but does anyone have any idea?
Regards
Scott

Hi Scott,
Thank you any way.
Last time, I met it and carried the tutorial on by compiling and copying manually. Then, I came back to set the ant.jar into path&classpath, and it worked.(ant build)
Today, I'm trying on "hello1" example, but can't get though.
Maybe it's still classpath and path issue, as I can't compile two servlet classes by javac from command line, but from Forte, it passed.
Cheers!

J2EE tutorial (June 17 '04) servlet example compilation error

This is a copy of my previous post on the same topic, but this one has a more self-desriptive subject line. Apologies for duplication.
I am trying the first servlet example in the J2EE tutorial, June 17, 2004, pgs 443 - 448. I have completed all the steps as described. However, the URL results in the following error. I would like to point out that I am using the URL http://localhost:8081/bookstore1/bookstore (instead of port 8080 because the admin console suggests that port 8081 is an available http port):
Assistance would be appreciated.

JWSDP Tutorial Problem - please help!

Hi!
I'm new to the Java Technology so I'm going through the JWSDP Tutorial provided by Sun. I have followed all of the steps set out in the 3rd chapter, however, when I enter this URL http://localhost:8080/gs, to run the example application I get the following error message:
HTTP Status 404 - /gs
type Status report
message /gs
description The requested resource (/gs) is not available.
Java Web Services Developer Pack/1.2
Does anyone know what this means? I will be very grateful for any kind of help.
Thanks.

Apologies for the lack of detail.
I have installed the Java Development Kit (j2sdk1.4.2), the Java
WSDP (jwsdp-1.2) and the tutorial (jwsdp-1_2-tutorial) on my C:\ drive.
The following have been set as the PATH variable:
- C:\jwsdp-1.2\jwsdp-shared\bin
- C:\jwsdp-1.2\apache-ant\bin
- C:\j2sdk1.4.2\bin
The tutorial states that the build.properties file
(<INSTALL>\jwstutorial12\examples\common\build.properties) needs to be
modified so I have made the following changes:
tutorial.home=C:\jwsdp-1_2-tutorial
tutorial.install=${tutorial.home}/jwstutorial12
username=<username>
password=<password>
host=localhost
port=8080
secure.port=8443
url=http://${host}:${port}/manager
- The tutorial.home variable has been set to the path to the directory
into which the tutorial was installed
- The username and password variables have been set to what was
specified upon installing the JWSDP
1. I have changed to the root directory, C:\jwsdp-1_2-
tutorial\jwstutorial12\examples\gs. I have compiled the source files
by typing the following at the terminal prompt:
ant build
The following message is echoed to the screen:

2. I have started Tomcat.
3. I have installed the Web application on Tomcat using Ant by typing
the following at the terminal prompt:
ant install
The following message is echoed to the screen:
[install] OK - Installed application at context path /gs
4. I have started a Web browser and entered the following URL to run
the example application:
http://localhost:8080/gs
It is at this point I get the error. I have read through the
instructions several times to ensure I have not missed anything. It is
not specified that the tutorial should be installed in a particular
directory, but I was wondering if it should be.

Problems with the jax-rpc testcase from the JWSDP tutorial

Hello.
I have e few problems with the hello case from the JWSDP tutorial.
Everything works fine during the build/compile/installation phase but when I'm accessing the url http://localhost:8080/jaxrpc-hello/jaxrpc, the server wont find the service and I get:
404 The requested resource (/jaxrpc-hello/jaxrpc) is not available.
I've trippel checked the environment settings and other properties and I don't know where to go to error check.
I've tried to install the client as well but it wont detect the service so I guess there is a problem on the server side.
I'm quite new to the whole "Web Service thing" So I would be happy to get som help.
Chris

if you run the tomcat manager application at http://localhost:8080/manager/list, what do you see? I suppose if you have successfully run the ant "install" task after "compile-server" and "xrpcc-server", you will see that your service is registered with its context path, but is not "running". This will be probably because of a runtime error. For further diagnosis of errors like these, I recommend to take a look at the log file at "<%JWSDP_HOME%>/logs/catalina.out".
If you are satisfied with this answer, please be so kind and assign some of your duke dollars to me ;-)

SIMPLEST servlet example please

Hi,
I was wondering if someone could post a java servlet example that accepts a string array (let's say we pass "A" and "B") and returns back a string array (let's say "1" and "2") without having to use a doGet or doPost. This would simply be passed as a value as one normally might, using a procedure or function.
Help on this is greatly appreciated. I am using this to access DB information, and already have the rest of the code finished, however I must implement this as a servlet.
Thanks...

Hello lafnjack,
A servlet is a kind of plugin-class that is connected to a HTTP-server to handle HTTP requests by interpreting the request itself and generating the response.
Therefore, a servlet is called through methods that are in parallel to the HTTP requests GET, POST and in some cases the other variants. Having said this, it should be obvious that a servlet has no more options for functioning than implementing doGet/doPost etc functions.

Compiled Tomcat Servlet Example & got JAR, not WAR?

Is there a basic reference on how to create a simple servlet with NetBeans 4.1 and deploy it to Tomcat?
When I created the project I chose Samples->Web->Tomcat Servlet Example, and yet it does not create a WAR file on compilation.
And of course once I'm past that I have to figure out how to edit the XML file, I gather.
I need a reference that will hold me by the hand and walk me through it once to kick start me.
After that I think I can make it without having to ask such newbie questions.

Hi,
not sure to what extent you are clear in build.xml file (done thru ant).
what i can tell you is, ant creates any archive file (be it .jar, .war, .ear) with the tasks named "jar" (<jar jarfile="yourfilename.jar"..>), "war" and "ear". But both war and ear are the extensions of the jar only.
You can achieve creation of any archive file with the jar task itself.
you need to take care of the following...
(1) you can /should edit the extension of the files at every stage.. first .jar and then .war and then .ear (if necessary) => basic flow
(2) at every step, you have to have a file inclusion inside the corresponding archive file..
say for example, for a .jar file you should include all the compiled .class files, and ejb-jar.xml (incase you use ejbs) and other built-in jar files....
In case of .war files (web archive) you should include the web.xml file, any static files (html, jsp etc), any tld files - it goes with your application's nature and requirement.....
fyi, i m including a sample build.xml file which i use for a webapplication, so it deals with war...
<?xml version="1.0" encoding="UTF-8"?>
<project name="ServletsReqDispFwd" default="deploy">
 <property name="top" value="."/>
 <property name="webinf" value="${top}/WEB-INF"/>

 <include name="**/*web*.xml"/>
 <include name="**/*application*.xml"/>
 <exclude name="src/**/*.xml"/>
 </webinf>
 <lib dir="${lib}">
 <include name="*.jar"/>
 </lib>
 <fileset dir="." includes="**/*.html"/>
 <classes dir="${classes}" includes="**/*.class"></classes>
 </war>
 </target>
 <target name="deploy" depends="clean,package">
 <copy file="${warfile}" todir="${tomcat.dir}" overwrite="true"></copy>
 </target>
 <target name="clean">
 <delete dir="${classes}">
 <filename name="*.class"/>
 </delete>
 <delete>
 <fileset dir="${top}" includes="${warfile}"/>
 </delete>
 <delete>
 <fileset dir="${tomcat.dir}" includes="${warfile}"/>
 </delete>
 </target>
</project>hope this contribues to a certain extent to help you edit the buildfile (xml file as you go) to meet your requirement.....

Trouble compiling servlet example

Hi All, I am trying out an example for servlets and I ran into trouble compiling the the file called "FormProcessingServlet.java" in tutorial located here: http://developer.java.sun.com/developer/onlineTraining/Servlets/Fundamentals/magercises/FormPostingAndProcessing/index.html
The exact problem happens in this line:
isStructure = context.getResourceAsStream(paramStructureFile[0]);
The error says:
FormProcessingServlet.java:127: cannot resolve symbol
symbol : method getResourceAsStream (java.lang.String)
location: interface javax.servlet.ServletContext
isStructure = context.getResourceAsStream(paramStructureFile[0]);
anyone else ran into this problem? How do I fix this? Thanks.

"cannot resolve symbol" means that the JVM can't find a particular class.
Adjust your systems classpath variable to include all the jar files that you use, I also add "." to include files in the current directory I'm working from.

Edited by: vinaysb on Sep 1, 2010 3:29 AM

there is not much help to give. Java already says what the problem is: the cart/util/BookException class is not on the application's classpath. That can indicate a missing library or bad deployment settings. Hard to say what it exactly is.
All I can say is: learn how a JEE application is properly packaged and deployed and with that knowledge try and figure out where the mistake is.
