implementing or using jdbc with servlets and jsp.Well, which do you want to do? Implement JDBC with servlets and JSP - a tricky job, but there's no technical reason why you couldn't for instance write a class which both extends HttpServlet and implements java.sql.Driver. Wouldn't recommend it, though

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.

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.

Interesting single sigon application project using jsp and servlet....Help.

A customer login's to my website using Enterprise login. I am supposed to have a link on my website to this other website(that also uses our Enterprise login details but hosted by other vendor/company on their server), and when I click this link the customes should automatically get logged in to this other website and get a welcome page(instead of login page).
Below are the sequence of steps that the other website wants me to perform to get to his welcome page(i.e bypass his login page).
FYI, I am planning to build a jsp page with a link to this other website. Can some body tell me how should I build the application(i.e) how jsp and servlets be build to interact to perform these operations. Any hep is greatly appreciated.
1.When a user clicks on to other website link(available on my website), the browser generates an HTTP GET request to the Other website's session servlet. User's name is one of the parameters of this request.
2.Other website receives the HTTP request and generates a unique session identifier for this user. An HTTP response to the end-user is then sent. The user's name and the session identifier are passed back as parameters in the redirect URL.
3.The browser sends the HTTP request (GET) to the Verification Service that was specified in the redirect message. The parameters (user name and/or session id) will be passed as URL parameters.
4.The Verification Service(of other website) authenticates the user. A redirect URL to it's sigon servlet(with parameter's User id and key) is then sent back to the user's browser.
5.The end-user's browser will perform the redirect (performing an HTTP get operation to Other website's signon servlet with the username and the digest key).
6.The other website will check if the parameter's passed is the same as the one passed earlier, if the user is who he says he is then he is redirected to the main page of the application.
7.The browser will then redirect the user to Other website's main page (welcome.jsp).
There seems's to be many calls to this other website that needs to be performed behind the scenes once a user clicks the link on my website.
Please suggest and help me out.........

Why are you trying to build a whole federated single sign on framework from scratch when you can just use/buy an existing and proven solution instead? There are a lot of security implication and trust issues involved for this so unless you already understand all of those I'd advise you not to re-invent the wheel. There are a lot of products available that do this. Try searching for '<vendor name> Access Manager' or OpenSSO.

Showing various images on browser using JSP and Servlet

Hello Guys!
I am starting to develop in Java and already I am facing a big problem.
If somebody will have some tip or suggestion, will be very well comings!
The application must present in browser images originnally of format TIF. As it is not a native format of the I.E. , I converted the image for JPG (without saving it on disk) and send it to the browser a encoded image (encode) using JAI library in one servlet had access by a JSP. Then, the structure of my application is thus:
1) an archive JSP draws the initial screen in browser and presents one input text.
2) later that the user places the parameter, I make an access to the database and read a quantity of images to be presented.
3) From there in the proper JSP, I use de tag img src to send image to the browser in agreement archive the amount of images.
It follows the code of the JSP:
<%
                int intI=0;
                int intCont=0;
                if(blnImagem == true){
                    out.println("<br>");
                    out.println("<table border=0 STYLE=border-collapse:collapse>");
                    out.println("<tr>");
                    for(intI=0;intI < Processo.intQtdImagens;intI++){
                       Imagem.strImgTif = Imagem.IndicarImagem(Processo.strNmPath,Processo.strSubPath,Processo.intNuImagem,intI);
                       out.println("<th>");
                       out.println("<table border=1 STYLE=border-collapse:collapse rules='cols'>");
                       out.println("<tr>");
                       out.println("<th>");
                       %>
                         <img src="ShowImg" WIDTH=100>
                       <%
                       out.println("</th>");
                       out.println("</tr>");
                       out.println("</table>");
%>and code on the ShowImg servlet:
        response.setContentType("image/jpeg");
        ServletOutputStream sos = response.getOutputStream();
        RenderedOp src = JAI.create("fileload", Imagem.strImgTif);
        ImageEncoder encoder = ImageCodec.createImageEncoder("JPEG",sos,null);
        encoder.encode(src);
        sos.close();The problem is if I have 10 images to present, it WILL BE it is executed 10 times and it passes 10 names of different archives, but in the page only the last image is presented 10 times. It is as if it processed the TAG to the end of everything in way that the value of the static variable Imagem.strImgTif was chore only with the last value and the same loaded image 10 times. How I make to solve this? Somebody has some idea?
THANK YOU !
Emidio

If I understand correctly what your problem is:
Do this in the jsp:
out.println("<img src=\"ShowImg?image=" + intI + "\" WIDTH=100>");
In the image servlet, get the "image" parameter and parse it as an int. Move the Imagem.IndicarImagem() call to the image servlet.

Consuming a Web Service using JSP and servlet

I have created a Web Service in Netbeans IDE 5.5. I developed a JSP to provide input to the Web Service, and a servlet that will pass the input to the web service through a request and outputs the result.
I am getting the following error:
HTTP Status 500 -

Any hints???

You probably should post to either the NetBeans website mailing list, or the Sun forum that supports the Sun Application Server, as the error is the result of a configuration error of one or both of these products. A file can't be found:
java.io.FileNotFoundException: http://localhost:8080/TestWebApplication/TestWSService?wsdl
note The full stack traces of the exception and its root causes are available in the Sun Java System Application Server Platform Edition 9.0_01 logs.

How to track the same session using both jsp and servlets

Hello, guys:
"how to use jsp and servlet to track the same session",
it seems to me my logoff.jsp never realize the session I established in my servlets.
Here is how I set my session in my servlets:
" HttpSession session = req.getSession(true);
session.setAttribute("userid",suserid);"
Here is how I invalidate my session in my logoff.jsp
" <%@ page language= "java" %>
<%@ page import="javax.servlet.http.HttpSession" %>
<%@ page session="false"%>
Our Session id is : <%= session.getId() %>
<% session.removeAttribute("userid");
session.invalidate();
%>
Our Session id is : <%= session.getId() %>"
but when I try to logoff using the logoff.jsp
I always get following error message.
"/home/jiao/jsp_webserver/tomcat/work/Standalone/localhost/syllabus/htmls/logoff_jsp.java:50: cannot resolve symbol
symbol : variable session
location: class org.apache.jsp.logoff_jsp

[Edited by: jiveadmin on Jun 18, 2003 10:33 AM]

So,
<%@ page session="false"%>
That means the jsp never instantiates the build in session object.
<%@ page session="true"%>
means jsp will instantiates a session object if there are no existing ones
how about I just delete the line,
does that mean the jsp will find the existing session object for me?
So I can do something like
Our Session id is : <%= session.getId() %>
<% session.removeAttribute("userid");
session.invalidate();
%>
directly.

After user has make his selection by entering the qty and ticking on the check box, he would click the "Add To Cart" button ... and this would call my servlet : AddToAddControlSerlvet.java

import java.util.*;
import java.util.ArrayList;
public class AddToCartControlServlet extends HttpServlet
     public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException,IOException

               DBClass dbClass = new DBClass();
               ArrayList cartList = new ArrayList();
               for (int i = 0; i < addList.length; i++)
                    String productCode = (String)addList;
                    int qty = Integer.parseInt(req.getParameter("Q"+productCode));
                    Products product = dbClass.getProductDetail(productCode);
                    double totalUnitAmt = qty * product.getUnitPrice();
                    double totalCartonAmt = qty * product.getCartonPrice();
                    Order order = new Order(product.getProductCode(),product.getProductDesc(),product.getBrandName(),product.getUom(),qty,product.getUnitPrice(),product.getCartonPrice(),totalUnitAmt,totalCartonAmt);
                    cartList.add(order);
               sess.setAttribute("cartList", cartList);

               ServletContext sc = getServletContext();
               RequestDispatcher rd = sc.getRequestDispatcher(url);
               rd.forward(req, res);
          catch (Exception e)
               System.out.println(e);
From here, i would get the list of items which user has selected and add to the cartList, then i would direct the user to CartDetails.jsp which displayed the items user has selected.
From there, user would be able to remove or to continue shopping by selecting other category.
How i do store all the items user has selected ... everytime he would wan to view his cart ...
As i would be calling from jsp to servlet .. or jsp to servlet ... and i do not know how i should go about in creating the shopping cart.

Hi !
Yon can use a data structure as vector and store the items selected by the user into the vector . Keep the vector in session using session object , so the user can access the entire shopping cart from anywhere in the application .
Then , you can change the cart accordingly .
Hope this works.
Cheers ,
Pranav

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.
http://yourserver/foo/foo.jsp
Hope this was helpful!!!

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.

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.

How to upload an html file using jsp and jdbc

Hi,
im trying to upload an html page using JSP and jdbc. but of no success.
my aim is to keep some important html pages in the database.the file size can vary.the file has to be selected from a local machine (through the browser) and uploaded to a remote machine(where the databse resides).
any help/sample code or pointer to any helpful link is appreciated.
thanks in advance
javajar2003

When uploading a file, I use a byte array as a temporary buffer..
So, you should then be able to store the byte array in the
database as binary data.
example>
//Temporary Buffer To Store File
byte[] tmpbuffer = new byte[860];
//Some Code To Upload File...
//File Should Now Be In Byte Array
//Get DB Connection and execute Prepared Statement
Connection con=//GET DB CONNECTION;
String sql=insert into TABLE(page) values(?);
PreparedStatement ps=con.prepareStatement(sql);
ps.setBytes(1,tempbuffer);
ps.executeUpdate();
//Close PS and Free DB Connection
..... and this method looks like you dont even have
to store the file in a byte array, you can just give
it the input stream.
ps.setBinaryStream(int, inputStream, int);
You may have to make several attempts at this. I have
uploaded a file and temporarily stored it in a byte array,
but have never from there stored it in the DB as binary
data.. but this looks like it'll work.
Good Luck!

When to use jsp,and when to use servlet?

I think that jsp and servlet can realize the same functions, because when run a jsp, it is transferred to a servlet program, so when to use jsp and when to use servlet?
I am now developing the input interface for a website, I just use jsp and javabean to connect to weblogic and database, and I didn't use servlet, Is there any unseemliness?
Thank you!

IMHO I use servlets to control the flow between my jsp's based on a number of factors in a webapp. For instance, user authorization. If a user has the authorization to conduct various administrative functions on an application (like change user rights, reset passwords etc) they will have access to specific buttons or links on some screens that others will not. I use servlets to establish what access rights a user has and direct them to the appropriate pages. I also use servlets to test data validity on form input screens. I know that I can also do this with JavaScript but that can be disabled by the client and in order to prevent that I also double check the form input from a servlet. All my jsp's do is display the results of a business process (which is held in a JavaBean or EJB) and the servlets act as the controllers for the application, connecting to multiple databases, verifying application state, flow control etc. I try to keep the jsp as simple as possible as some of them are maintained by html developers who lack the necessary experience to write java code. I hope this helps.

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?

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.

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
