JSP and Servlet Version Number

Dear all:
Does any one know how to find out the version number of JSP and servlet. I am currently using IBM WSAD as development tools.
Thanks for your attention.

The web.xml would also help. Look at the dtd/schema definition in web.xml -
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
     PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>.....indicates servlet 2.3 specification (jsp 1.2, j2ee 1.3)
where as
<?xml version="1.0"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
    version="2.4">indicates servlet 2.4 spec (jsp 2.0, j2ee 1.4)
cheers,
ram.

Deploying a WAR file containing .jsp and servlets (also uses JNI)

Deploying a WAR file containing .jsp and servlets (also uses JNI) on Windows 2000
We had problems making it initially work on Sun ONE Web Server 6.0 Service Pack 1 because of lack of good iPlanet Web
Server documentation on deploying such files.
This is how we went about it:
1) Make one of the servlet and JSP (must call another Java Class) web application (.war) examples work with iPlanet Web
Server.
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\HelloWorld\HelloWorld.war
and
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
a) Go to your Web Server Administration to deploy the application using GUI Web Application Deploy.
(We usually use command line, we experienced some issues with the GUI version, but maybe it is fixed in the new Web Server
service packs)
From browser, open http://yourserver:8888/
Click on Select a Server:Manage
Click on Virtual Server Class
Click on https-yourserver
Click on the Web Applications Tab
Then, click on Deploy Web Application
Enter the following -
WAR File On: Local
WAR File Path: C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Application URI: /jakarta
Installation Directory: c:\iPlanet\examples\jakarta-examples
By clicking on OK it deployed the application.
I can verify that it is deployed by selecting "Edit Web Applications" and I see the following entry:
Edit     /jakarta     c:/iPlanet/examples/jakarta-examples
Also, c:/iPlanet/examples/jakarta-examples should have the similar following directory structure ..
- [images]
- [jsp]
- index.html
- [servlets]
- [META-INF]
- [WEB-INF]
- [classes]
- [tlds]
- web.xml
- index.html
I restarted the server and accessed it using the following URL from my IE browser:
http://yourserver/jakarta/index.html
Then I clicked on the JSP Examples and tried some JSP examples.
b) Alternatively, you can also deploy the same example from the command-line.
Make sure C:\iPlanet\Servers\bin\https\httpadmin\bin\ is in your path
wdeploy deploy      -u /jakarta
          -i yourserver
          -v https-yourserver
          -d c:\iplanet\examples\jakarta-examples
          C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Restart the web server (I don't think you have to restart, but .. might as well).
2)Deploy your web-application
My Foo.war has the following structure.
You can use jar tf Foo.war to look at the file contents from command line (assuming you have JDK installed and the bin is
in your PATH)
Foo.war
- [META-INF]
- [WEB-INF]
- web.xml
- [classes]
- Bar.class
- MoServlet.class
- [lib]
- ThirdParty.jar
- [natlib]
- extlib.dll
- foo.jsp
Here is our application scenario:
foo.jsp uses a class call Bar (it is not in any package). The Bar java class uses classes from ThirdParty.jar. The
ThirdParty.jar in turn uses JNI to load library extlib.dll. foo.jsp also calls /servlet/Mo as well.
Now to deploy it, do the following:
(a) Make sure that within foo.jsp, you import the Bar class ( I don't know why you have to do it, but if you don't you get
JSP compile error).
<%@page language="java" import="Bar" contentType="text/html"%>
(b) Check web.xml (for Servlets)
Within web.xml, make sure you have the following mappings:
<servlet>
<servlet-name> MoLink </servlet-name>
<servlet-class> MoServlet </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> MoLink </servlet-name>
<url-pattern> /servlet/Mo </url-pattern>
</servlet-mapping>
(c) Deploy the application
Using command line:
wdeploy deploy      -u /foo
          -i yourserver
          -v https-yourserver
          -d c:\iplanet\examples\foo-dir
          Foo.war
(d) Change web-apps.xml file (for picking up ThirdParty.jar)
It is located in
C:\iPlanet\Servers\https-yourserver\config
You should see something similar to following after successful deployment.
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true"/>
Change it to look like following to pick up the ThirdParty.jar
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true">
<class-loader reload-interval="300"
          classpath="C:/iPlanet/examples/foo-dir/WEB-INF/lib/ThirdParty.jar"
          delegate="false"/>
</web-app>
(e) Change jvm12.conf file (for JNI)
It is located in
C:\iPlanet\Servers\https-yourserver\config
Add or uncomment the following lines:
#optional - just helps with instrumenting the jsp and servlet code
jvm.include.CLASSPATH=1
jvm.enableDebug=1
nes.jsp.enabledebug=1
jvm.trace=7
jvm.verboseMode=1
#required for JNI
java.compiler=NONE
jvm.classpath=.;C:\JDK1.3.1\lib\tools.jar;C:/iPlanet/Servers/plugins/servlets/examples/legacy/beans.10/SDKBeans10.jar;
jvm.option=-Xrs
jvm.option=-Xnoagent
# not sure if this is needed for iPlanet web server
jvm.option=-Djava.library.path=C:/iPlanet/examples/foo-dir/natlib/ -Djava.compiler=NONE
(f) Change magnus.conf file (for JNI)
We HAD to change this file in order for ThirdParty.jar file to pick up the native C++ code using JNI. Apparently, the
iPlanet Web Server doesn't pick the Environment Variable Path. Because when we had the directory containing the DLL just
in Path, it didn't work.
Change Extrapath directive:
ExtraPath C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
to
ExtraPath c:/iPlanet/examples/foo-dir/natlib;C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
(g) Apply changes from the Web Server Administration Console and Restart the web server.
You should be able to see the behaviour that you want from your application.

Hope this was helpful!!!

SQLJ JSP and SERVLETS which Environment?

Hello,
I am attempting to run the samples on Chapter 5 of the
following documents with partial success.
http://technet.oracle.com/docs/products/oracle8i/doc_library/817_
doc/java.817/a83726/oraext2.htm
http://download-west.oracle.com/otndoc/oracle9i/901_doc/java.901/
a90208/oraext.htm#1015820
1. Do I need the Apache+Jserv environment to run SQLJ and JSP?
2. What do I need to do run SQLJ on oc4j if possible?
3. I dont know how to load(?) and/or run this .sqljsp file.
<%@ page language="sqlj"
import="sqlj.runtime.ref.DefaultContext,oracle.sqlj.runtime.Oracl
e" %>
<HTML>
<HEAD> <TITLE> The SQLJQuery JSP </TITLE> </HEAD>
<BODY BGCOLOR="white">
<% String empno = request.getParameter("empno");
if (empno != null) { %>
<H3> Employee # <%=empno %> Details: </H3>
<%= runQuery(empno) %>
<HR><BR>
<% } %>
<B>Enter an employee number:</B>
<FORM METHOD="get">
<INPUT TYPE="text" NAME="empno" SIZE=10>
<INPUT TYPE="submit" VALUE="Ask Oracle");
</FORM>
</BODY>
</HTML>
<%!
private String runQuery(String empno) throws
java.sql.SQLException {
DefaultContext dctx = null;
String ename = null; double sal = 0.0; String hireDate = null;
StringBuffer sb = new StringBuffer();
try {
dctx = Oracle.getConnection("jdbc:oracle:oci8:@", "scott",
"tiger");
#sql [dctx] {
select ename, sal, TO_CHAR(hiredate,'DD-MON-YYYY')
INTO :ename, :sal, :hireDate
FROM scott.emp WHERE UPPER(empno) = UPPER(:empno)
sb.append("<BLOCKQUOTE><BIG><B><PRE>\n");
sb.append("Name : " + ename + "\n");
sb.append("Salary : " + sal + "\n");
sb.append("Date hired : " + hireDate);
sb.append("</PRE></B></BIG></BLOCKQUOTE>");
} catch (java.sql.SQLException e) {
sb.append("<P> SQL error: <PRE> " + e + " </PRE> </P>\n");
} finally {
if (dctx!= null) dctx.close();
return sb.toString();
%>
I named above file as test2.sqljsp then I tried these procedures:
a) $ ojspc test2.sqljsp --these created all the files
b) $ loadjava -u -v scott/tiger _test2.class -resolve
this generated:
initialization complete
loading : _test2
creating : _test2
resolver :
resolving: _test2
errors : _test2
ORA-29521: referenced name test2$_jsp_StaticText could not
be found
ORA-29521: referenced name test2SJProfileKeys could not be
found loadjava: 2 errors
c) listed the directory and both these files are there but it
cannot resolve or find it?
d) I recall reading something about publishjsp command but I have
to establish a session shell with OSE? this part is very
confusing and am not sure what to do here.
e) not sure if i need to publish the loaded class (create a
procedure? so it can be known to the rest of plsql?)
A step by step procedure is very much appreciated. fyi.. I
have Oracle 8.1.7, + oc4j, I can run sqlj from command line
and class files generated I can run. I can also run JSP and
servlets on the oc4j accessing the database. It is this SQLJ
that throws me off balance. If you include Jdeveloper steps
ro run SQLJ thats also welcome.
Thanks in advance for kind responses posted.

In many Model-View-Controller web applications implemented using J2EE, servlets are as controllers to direct the flow between the model and view. While servlets can output HTML code directly, it is much better to use JSPs for the most part. JSPs contain HTML and possibly Java scriptlets. The J2EE container will typically compile JSPs into servlets. While you could use a JSP as a controller, there are drawbacks to that approach. To minimize the amount of Java code in your JSPs, you can either use the tags provided by the JSP spec or use tag libraries written by someone else or yourself. See the JSTL for one such example.

What server to install on win XP for learning jsp and servlets

Hi !
If any one knows what server/servlet I have to install if I want to test
JSP and SERVLETS ?
How I'm installing it if I'm using JBuilder and windows XP
Tank's

If I will download the Tomcat 4.1.24, I will must to use jsp 1.2 and servlet 2.3 version ?
I have jsdk2.1 now declared in Jbuilder, is it also ok for using tomcat ?
If i"m using jbuilder, what the next step after i will download it ?
The tomcat has some shared folder with jsdk/servlet ?
Tank's !
I have so many question, because I just started with jsp/servlets.

Need help in JSP and Servlets

Hi friends,
[please forgive me if i am posting this in the wrong forum, all seems same to a fresher]
Now, to my problem..i need a suggestion, a way or a method to implement the following!
I am supposed to create a servlet that reads data from oracle database. Once i retrive the data (for example: 6 rows of a table having 4 attributes), i am supposed to pass this data to a JSP page where the data has to be formatted and displayed properly. If i call the same servlet from a different JSP, i should be able to access the data in that JSP and format it in a different way. How do i pass the data to JSP? what method i can use to achieve this task?
Note: I already know about PrintWriter pw = response.getWriter(); and then printing the formated HTML page..but i want to keep the formatting to JSP part and send only the data part that i can access in JSP
Thanks in adavance

How to upload a file into server using j2ee jsp and servlet with bean?

How to upload a file into server using j2ee jsp and servlet with bean? Please give me the reference or url about how to do that. If related to struts is more suitable.
Anyone help me please!

u don't need j2ee and struts to do file uploading. An example is as such
in JSP. u use the <input> file tag like
<input type="file"....>You need a bean to capture the file contents like
class FileUploadObj {
    private FormFile srcFile;
    private byte[] fileContent;
    // all the getter and setter methods
}Then in the servlet, you process the file for uploading
    * The following loads the uploaded binary data into a byte Array.
    FileUploadObj form = new FileUploadObj();
    byte[] byteArr = null;
    if (form.signFile != null) {
        int filesize = form.srcFile.getFileSize();
        byteArr = new byte[filesize];
        ByteArrayInputStream bytein = new ByteArrayInputStream (form.srcFile.getFileData());
        bytein.read(byteArr);
        bytein.close();
        form.setFileContent(byteArr);
    // Write file content using Writer class into the destination file in the server.

Time_building_block_id and object version number

Hello,
could someone help me out with an explanation how the time_building_block_id and object version number to be interpreted?
Are these independent? What actions create new ID and new ovn?
My first idea was that one ID can have different instances in the table with different object version numbers. However I found cases belonging to the same parent buildingblock where both the id and ovn are different.
So based on this only one of the columns could be primary.
However for the joins both are used typically at the same time, suggesting that the two together constitutes a primary key.
Are the DETAIL level records belonding to the same DAY level record to be treated as co-existing entries and their measure to be summarized? Or only the latest (bigger ovn?) to be considered, so it is an updated version of the record with the previous ovn?
thanks!

The version number in the TC Building blocks is used to identify changes to timecard building blocks. It is not the same as an object version number on a record in a table.
OTL keeps an audit history of all changes to the timecard, at whatever level they occur. It uses this in retropay processes to identify the 'true' hours to use.
TC Building blocks have a 'scope', for example there are building blocks at these levels:
Timecard
Period / Application
Day
Detail
If you entered 8 hours on a new timecard for Monday 07/09/09 it would create a building block record for that date and call it version 1.
If you later make a change to that DAY, OTL will create a new record with version 2. Say this one shows 7 hours.
OTL can then interpret this as -8 + 7 = -1 and make the appropriate adjustment.
Hope that helps explain it!
Regards
Tim

Implement SSL in JSP and servlets

hi there,
i needed some help in implementing ssl in JSPs and servlets. My idea was to have a login page and also use it where sensitive data is being sent. I have used the basic socket programming (socket.class and serverSocket.class) in GUI applications using threads to listen and send simultaniously and understand how it works but how do I implement it in JSP and servlets and where do i store the certificate?
i do know that using SSL sockets is very much the same as using the normal sockets.
can anyone tell me any useful links or give me a step by step guide how to implement it and which classes to use
your help would be very much appreciated.
mani

hi,
soory for late reply.
i think you need to use keytool program in your JDK to generate a certificate signature file and you need to configure the server.xml to open and use the HTTPS port. I have not had any additional info on this but i would assume that you simply enter https:// on the file you wish to load in your form and it should use the HTTPS port provided it can find the certificate which must be stored somewhere in your tomcat web server. i would recommend you see tomcat website or search on google for "ssl support in tomcat".i hav not had time to look into this but i will as soon as i am free from my work load.

How to setup my computer to run JSP and Servlets

I want to setup my computer to run JSP and Servlets.
What kind of Servers and other tool i need to install to run JSP and Servlets.
Plz, Help me to start my work on JSP.
Regards,
Usman Ali

hello
JSP and servlet is web programming, may be little bit different to development local application.
1st, you should have two computers: one is server and the other is local workstation. This server should have a static IP address, that other people can go into your server. Workstation is any computer normal you use it.
2nd, you need to setup your server in: OS(linux or windows 2000), web server (jrun, apach or Tomcat etc. ), as well as install JDK, servlet.
3rd, your local workstation just use as programming editor and open a browser to testing, anytime you write your code, then ftp to server to test.
Reality, you have many technical thing to solve, eg setup web server etc. However, you can write your source code and test it, then open to outside people.
hope to helpness, if anything don't uderstand, you can post again or send email to me [email protected] Since I just have setup this configuration in my university for my project.

Load balancing for JSPs and servlets

Hi:
          I am using IIS as the proxy server, with the WLS plug-in, to a WLS
          cluster. This provides round robin load balancing just fine. Will it
          provide weight based load balancing if I set 'weblogic.system.weight'
          differently on each server, or is that not relevant for clustering JSPs
          and servlets?
          Sincerely,
          Ashish


Currently the plugins ( for NES, IIS and Apache) just use the round robin
          algorithm. the property
          weblogic.system.weight is used only be weblogic's replica aware clusterable
          RMI/EJB stubs.
          To use this property for your JSP/Servlet load balancing you have to use
          weblogic server as proxy fron-ending your weblogic cluster.

Basic jsp and servlet question (JSP Model 2)

Hi
I want to make an website where i use JSP Model 2 architecture. However I got a basic question
1. I need to separate business logic from presentation with the use of jsp and servlets. Meaning I want no html code in the servlet. Can you give a simple example of how this can be done? If I map my implementation of httpServlet to a jsp page in web.xml and override doPost() and doGet(). The calls to the jsp page comes to the servlet as it should. I want to process some methods (calling sessionbeans or similar which in turn calls entitybeans) and then show the jsp page.
How do I show the jsp page without mixing html in the servlet as I've done below:

You should treat your servlet class much like a controller, where you can then use JSP as the view. The way you achieve this is to use the forward() method in RequestDispatcher.
Say you've got a servlet class org.yoursite.controller.YourController:
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
//Set some value for use in the JSP file associated wth me
req.setAttribute("greeting", "Hello world!");
//Done with our business logic, off we go to the JSP file
ServletContext app = getServletContext();
    RequestDispatcher disp;
    disp = app.getRequestDispatcher("/some/jsp/file.jsp);
    disp.forward(req, resp);
}Now in your JSP file:
<h1>Example</h1>
<div>
I just want to say <%= request.getAttribute("greeting") %>
</div>Going to that servlet now executes business logic and then points to the JSP file for the view. You can forward from servlet to servlet too if needs be. The string you pass to forward() is whatever would be in the URI of the request so any <servlet-mapping> configurations in web.xml are used ;)
There is some pretty in-depth documentation on the J2EE blueprints website, namely service-to-worker and front-controller patterns. I dare say if you're looking for this sort of code you'll want to look at the composite view pattern too (also on blueprints).

i wil give up on talking about stupid gossip
you must act professional and i you can't help it's ok
so plz i juste want help
i'm so busy finishing my studies
when it comes to talk about development with tomcat and eclipse together i'm new so i need some advices,so plz let's be serious!
i'm working hard to finish my project!Try to communicate less like a monkey with electrodes attached to it's genitals. This means stop using words like "plz" and write "please" instead.
If you want specific help with a specific problem then you should ask a specific question. "help, JSP and SERVLETS" is not a specific question. And you should also note that if your specific question is about Tomcat specifically or Eclipse specifically then you are in the wrong place to begin with.
So do you want to try again?

JSP and servlets

Am I correct in assuming that JSP is an extention of servlets and that to learn JSP in effect means learning about servlets? My point is, is JSP the superior technology a bit like learning JDK1.4 is now a pointless excercise as it has been superceded by 1.5 ?
thanks

Am I correct in assuming that JSP is an extention of
servletsYes.
and that to learn JSP in effect means
learning about servlets? No. This isn't necessary, as a matter of fact, it is one of the reasons why JSP exists - so people with little or no Java knowledge can build dynamic web sites using Servlet containers, assuming they have Java programmers behind them to build the tags / glue to the web app.
Still, I say having basic understanding of Servlets (at least) will help you out.
My point is, is JSP the
superior technology No. JSP has a different role. It makes display easier to code for non-Java programmers (looks more like HTML/XML), and easier to support and understand later on.
JSP does horribly bad at complex application control, data selection and manipulation, or as an interface to external resources. Java and Servlets are better at these tasks (but conversly, are horrible to work with for display purposes).
They are different, JSPs and Servlets, in what task they do. J2EE is far superior when you use them both appropriately.
a bit like learning JDK1.4 is now
a pointless excercise as it has been superceded by
1.5 ?No.
JSP is a newer technology, but should not be used to replace Servlets, but used along side Servlets to provide a better designed and manageable application.
Let the servlets control what pages the user sees when, to gather data, to talk with external resources. Then forward to a JSP which simply displays what the Servlet did all the work in getting.

Good Book on JSP and Servlets

Hi,
Can anyone recommend a good, recently published book on JSPs and Servlets?

Things on the Internet may be up to date, but they
aren't necessarily as usable as a book.
For example. I am just trying to learn Ant. There's
the Ant user manual at http://ant.apache.org/manual/
for a start. But to find anything you have to click on
a link, then on another link, then on another link.
And it doesn't have an index so even if you know what
you are looking for, you still have to start at the
beginning and click randomly until you find it. And
you can't easily browse through looking for
interesting things.
Not to mention that it doesn't give you any
suggestions on what to do and why. It simply describes
the various XML elements used by Ant. For example it
may be possible to have an element which is like a
subroutine, so you can call the same code from
multiple targets. But if it is, I haven't found out
how yet.
Sometimes a book is better. In this case it would be.I agree with DrClap. Books do have a shelf life in IT, but they're definitely worth having.

How to cluster the war file conatining the jsp and servlet by using wl6.0sp1?

There three wlsever6.0 sp1.
          One is admin server and doesn't join the cluster.
          Two servers are cluster server.
          I use the admin console to deploy the war file and the war file conatains
          the jsp and servlet.
          How to config the one of the clustered servers as the primary one, so that
          the client can request the jsp?
          If the one of the clustered servers is closed, can the client be redirected
          to another clustered server?
          Does the proxy server need to be exist?
