Using javadoc and jsp

          I'm supposed to javadoc my application. Can this be done? Any advice or
          tips? References to documentation?
          Thanks

I tried it out and it doesn't work. The jsp compiler inserts its own
          description before the class declaration. The rest of the information
          generated by javadoc is pretty much useless. Clearly javadoc and jsps were
          never meant to go together. Too bad.

When to use servlets and jsp in an application like shoping cart?

Hi All
I m going to design and implement a web application using servelts and jsp. I am still at its requirements analyze stage.
The application is almost likely a shopping cart. So if any of you have the deep knowledge about this domain with servlets and jsp please help me for a good design. What I realy need to know is that
1. what are the core requirements for a shoping cart ?
2. use cases ?
3. best way to follow mvc with servlets and jsp for it?
you can answer to this at the abstract level. no need to go in detail.
if you have any documents like design and use cases mail me to [email protected]
your cooperation is highly appreciated in this regards.

Download local file using Servlet and JSP

Hello,
I will like to use a browser to download file on local system using serlvet and Jsp technology. Does anyone have any idea how to do it?
Any comment will be appreciate.
Thanks

Well you can just put the file in a folder that is accessible to the web server. Then have a link point to that file. That will cause the web browser to download the file.

URGENT.........File Upload using Servlets and jsp

I am a new servlet programmer.......
iam using tomcat server......
can any one pls help in writing code for file upload using servlets and jsp without using multipart class or any other class like that....
Please URGENT..

Slow down! "Urgent" is from your perspective alone. I, myself, am not troubled or worried in the least.
hi ugniss
thanks for ur reply....sorry i was not
y i was not asked not to use multipart class or any
other class like that...is there any other
possibility to do file uploading from jsp to
servlet...
Just as an aside, a JSP is a Servlet. But even if I move beyond that, the question does not make sense. If you want a "JSP to upload to a Servlet", then simply do so in memory. You are still (likely) within the same scope of a given request. However, if instead you are referring to a JSP that is displayed on a browser, then really you are talking about HTML, which is what the browser will receive. And since you are now talking about a browser, your only real, viable option is a multi-part file upload. So, it is either server or it is browser. And either way, the question leads to very established options, as outlined above.
the main concept is.. in the browser the user selects
a particular file and clicks the button upload..after
clicking upload the jsp should sent the file to the
servlet in streams...there the servlet gets in and
saves in a server location........this is wat i hav
to do...
Okay. So, after reading my previous (redundant) paragraph, we have arrived at the crux of the issue. You have a JSP that will be output as HTML to a client (browser) which you want to upload content to your server (handled by a Servlet). So, you are now stuck again with multi-part. The requirement to not use multi-part is non-sensical. You can overcome it, say, if you write your own applet or standalone Swing client. However, if your users are invoking this functionality from a browser, you are limited by the options that W3C has provided you. Use multi-part.
is there aby possibilty to do this.....can any one
pls help....Take the advice to download and review Jakarta Commons FileUpload. Inform your management that their requirement makes no technical sense. Research on your own. There are dozens of examples (and tutorials) on file upload using multi-part. Embrace it. Live it. Love it.

File Upload using struts and jsp

Hi,
Anybody have sample coding for uploading files into the database using struts and jsp.
Thanking you in advance for providing the sample coding.
Veena

Hi Veena,
In Strutsconfig.xml you have to configure data sources like this
**************strutsconfig.xml******
<data-sources>
<data-source
type="org.apache.common.dbcp.BasicDataSource">
<set-property property="driverClassName"
vlaue="oracle.jdbc.driver.OracleDriver"/>
<set-property property="url" vlaue="jdbcracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SID =ORCL)))"/>

<set-property property="username"
vlaue="scott"/>
<set-property property="password"
vlaue="tiger"/>
</data-source>
</data-sources>
Now here is how to get data source
public class LookupAction extends Action
public Double getQuote(String symbol,
HttpServletRequest request)
throws Exception
Double price=null;
Connection conn=null;
Statement stmt=null;
ResultSet rs=null;
DataSource dataSource=null;
try
dataSource = getDataSource(request);
conn= dataSource.getConnection();
stmt= conn.createStatement();
rs= stmt.executeQuery("select * from stocks where" + "symbol='" + symbol +"'");
if (rs.next())
=======================
After you can use the coding what I posted earlier.
For that you need to create a table with attachment as a CLOB col.
then with prepared statement I am setting value .
Plz try your self every thing ok you can get that.
all the best
bye

How to create an InputSelect using ADF and JSP

I looking for some docs/instructions on creating "an InputSelect using ADF with JSP".
Thanks,
BG...

Ok here are the Steps
1) Open the JSP editor for the page in Question.
2) In the Data Control palette select the item that you want to become the poplist and change the "Drop As" poplist to "Single Select List"
3) Drag the field into the page. You'll get an empty poplist which implements the <html:select> and <html:optionsCollection> tags.
4) With the JSP editor still open click on the "UI Model" sub-tab in the Structure pane
5) Select the field you've just dragged in - then right click to get the context menu and choose "edit"
6) Change the List Binding Mode poplist to "LOV Mode"
You're then taken into a couple of screens where you can select the Source VO for the poplist, and the destination dataset, along with the thing you want for the Label and the Value.

Use UIX and JSP together

I have some existing jsp application . I want to integrate it with UIX application that is generated from JHeadStart . jsp application is just 10% of whole project.
I am not sure this is a good way or not . May be We should use JHeadstart to generate JSP more than UIX . but I think it 's more powerful if I use JHeadstart to generate UIX application .
What do you recommend for this ?
and if we have to use both together . How dose JSP application pass parameter to UIX application ? and How dose UIX pass parameter to JSP ?. and How UIX use the parameter that 's sent form JSP ?
thanks in advance

If JSP is only 10% you might want tpo consider migrating these pages to UIX.
If this is not an option, you should be able to use both UIX and JSP pages. However, make sure you create separate struts-config.xml files for the JSP-based subsystem and the UIX-based subsystem. This requires two se[parate ViewController projects, that act as one web application. The same setup that has been aplied to Th JHeadstart demo application in Jhs 10.1.2.1. Check out this article from Duncan Mills as well:
http://www.oracle.com/technology/products/jdev/howtos/10g/StrutsMultiConfigs/struts_multiconfig_howto.html
One addition to this articel: the source path property of the ViewController projects shopuld be the same as well.
As far as communication between the pages is concerned: this is no different then between UIX pages. You can pass request parameters around, and since the pages are running in the same web app, they share the same HttpSession.

User Authentication using Servlet and JSp

Hi,
I am developing a web app where i need to implement user Authentication to allow members to view and upload files on a certain directory say /data
For this i am using a servlet as a controller which then forwads request to other jsps/servlets based on user response. I tried using servlet mapping in web.xml so that all browser requests would be directed to controller servlet and would branch from there on. However the problem all RequestDispatcher.forward() requests redirected to the servlet putting it in a loop.
Is there another way to achieve this. (Apart from using form-based Basic Authentication).
I am using Resin 1.2.8 servlet/jsp container.
Any response as soon as possible would be appreciated.
Thanks,
Kushagra

RequestDispatcher.forward() cause the HTTP request to be sent through the request processing flow as if the original request for the resource being forwarded to.
It seems the servlet mapping you are talking about in web.xml should be made more specific. i.e. the mapping should be such that only your so called controller servlet will match up.
You might want to specify the mapping for the controller servlet to be noticeably/effectively different from the mapping for other servlets and JSPs.

Can we use frames and jsps together..

Is it good to use frames with jsps.performence wise..bcos when iam calling jsps in frames it taking more time..to laod..
regards,

Remember, 2 frames == 2 HTTP requests. 3 frames == 3 requests, etc.
It will take longer of course. To think otherwise is crazy. However there are times when the benefits are there. I've used them, expecially if it's a situation where taking a little longer on the initial load makes all other accesses faster. This is particularly the case when I've got a fancy UI that uses lots of graphics. I don't need to load the graphics more than once so I put them in separate frames and only have one frame (which is mostly text) change content.

How to use servlets and JSP for my homepage?

servlets and JSP are server-side program. If my homepage is on some web-hosting websites, can I upload the servlets and JSP to run it? if possible, where can I find such a web-hosting place?
sraiper

Not many hosts offer JSP or Servlet support (and some do but then stop and never give you a refund, grrrrrrr!!!!).
Also, ones that do support it can often be more expensive. There are some free ones but all the one's I've come across have problems that made them unsuitable for my needs.
Here is a list of hosts that support Java:
http://www.thejspbook.com/resources/category.jsp?id=1005&name=JSP+web+hosting
I can't comment on any from that list, however I use http://www.positive-internet.com they are a bit pricey but they have excellent support and are always happy to help with any Tomcat (the JSP/Servlet server they use)configuration issues or needs that you may have.

How to send group SMSes by using KvanttiSMS and JSP

Hello again , I would want some help in implementing an SMS module that sends out a SMS message to a selected group of individuals from a database of several different groups .
Now I have done a JSP GUI to allow the user to send a single SMS to one person .
And my initial JSP codings for the Group SMS GUI were scrutinized and was said to be not functional by my lecturer .
This is one of the technique that I know currently to send out an SMS :
Connect to the database and get all the names of the groups .
Using a while(column.next()) statement , the results will be placed into a drop down list in the JSP.
The user selects the group from the drop down list and types the message as normal .
The user presses the submit button and goes to the next JSP page (the 2nd JSP page sends out the SMS).
The 2nd JSP page gets the group parameter and the message . Both parameters are placed into a string object.
Using the string "group" object , another connection to the database is called .
The database is called once again to retrieve handphone numbers that belong to groups that matches the string "group" object.
using another while(column.next()) statement . The Sms terminal is called , initialized and used to send the message accordingly to the number of results .
So is there any comment about this ? Please tell me what I should do if my method is wrong.

I'm sorry ,
actually the SQL statement uses the string "group" object to retrieve handphone numbers that belong to a person who is inside the same group as the string "group" object .

Problems using JNI and JSP in WebLogic 6.0

Hello everybody. My problem is that I've got a Java class that is called from a JSP. That class connects to a C function and it returns a String. A want this string to be shown by the JSP. The code is:
JSP
<html>
<head>
<title>prueba JNI</title>
</head>
<body>
<%@ page import="ejemplosJNI.*, conversiones.*;"%>
<%
Texto texto = new Texto();
out.println(texto.realizado());
%>
</body>
</html>
Java class
package ejemplosJNI;
public class Texto
private native String getLine(String prompt);
String input = null;
public static void main(String args[])
Texto t = new Texto();
static
System.loadLibrary("MyImpOfPrompt");
public String realizado()
input = this.getLine("Mando una l�nea desde Java");
return input;
C function
#include <stdio.h>
#include <jni.h>
#include "Texto.h"
JNIEXPORT jstring JNICALL
Java_Texto_getLine(JNIEnv *env, jobject obj, jstring prompt)
char buf[128];
const char str = (env)->GetStringUTFChars(env, prompt, 0);
(*env)->ReleaseStringUTFChars(env, prompt, str);
return (*env)->NewStringUTF(env, str);
I compile de C function and put the .dll library in the 'bin' folder in webLogic.
When I call the JSP, I get the next exception:
Servlet failed with Exception
java.lang.UnsatisfiedLinkError: getLine

Is there any place where I have to put the .dll?
Is there any place where I have to put the generated .lib?
Where do I have to put the Texto.h file generated with javah?
Can anybody help me to solve this problem?
Thanks in advance.

Hi, jschell! Maybe you can see my problem if I give you the code. My Java class and the C funtions are:
Java class
package ejemplos.cadena;
public class Texto
private native String getLine(String prompt) throws Exception;
String cadenaFinal = null;
public static void main(String args[])
Texto t = new Texto();
static
System.loadLibrary("LibreriaCadena");
public String realizado(String cadena)
try
cadenaFinal = getLine(cadena);
catch(Exception e)
System.out.println(e.toString());
return cadenaFinal;
C code
#include <stdio.h>
#include <jni.h>
#include "ejemplos_cadena_Texto.h"
JNIEXPORT jstring JNICALL
Java_ejemplos_cadena_Texto_getLine(JNIEnv *env, jobject obj, jstring prompt)
int cero =0;
int division = 10 / cero;
const char str = (env)->GetStringUTFChars(env, prompt, 0);
(*env)->ReleaseStringUTFChars(env, prompt, str);
return (*env)->NewStringUTF(env, str);
I have done something like "int division = 10 / cero;" in order to get an exception in my C code. When I run my Java class I get an error message and the application breaks. I would like to know how to catch the C exception in order to pass it to my Java class that can manage it into the try-catch clause. I have read I have to use something like "FindClass" or "ThrowNew", but my problem is that I have no idea about C programming.
Can you help me?
Thanks for your time.

Java.lang.NoSuchMethodError using beans and JSP

Yeah, that worked great, thanks a lot. I thought that JSP compiled when you changed it and then visited it, but i've tried that. I just ran ant stop start on my server and it's all working.
Thanks again :)

Passing a url parameter to a method using ADF and JSP

Hi
(JDEV10.1.3 : ADF BC, JSP, STRUTS)
I have a text input on my JSP Page which I need to pass the content as an argument for the dataaction which is implemented in my application Module as a method to set the where clause of a query. I do not know How to set the Method's NDValue. I have tried:
NDValue='${pageContext.request.parameterMap[ComplexID]}'
But it always returns null
hint: ComplexID is my txtBox name on the JSP page.
I need to pass request.getParameter("ComplexID") but as an NDValue it is not accepted.
note that ComplexID is not a databind object, It has been created by myself as an HTML element.

What result do you get when you enter the following into your browser:
http://mylocalhost_IP/path/to/component/questions.cfc?method=getQuestionsXML&quizid=2 ?
(Replace http://mylocalhost_IP/path/to/component/ with the correct path to your component)
Are the results valid/well-formed XML? Is there any extraneous text that might interferre with the XML processing? I noticed your xPath was looking for an element called "question s" - Is that the correct name of the element in your XML? Is there really a space in the name?
See if you can troubleshoot the issue using your browser first before adding it back into the Spry call.
Hope that helps!

File download using servlet and jsp. File Dialog comes twice

Hi
I was trying to download a file using servlet. There is a link which calls the servlet. When I click on the link file dialog box comes up. On selecting Open it again shows me the file dialog box. I changed the method from POST to GET and it worked properly.
My question is why does it work with GET and not with POST. I am aware of the differences between POST and GET but am not able to come to a rational explanation for this behaviour.
Please if anyone can explain this to me I am going crazy thinking an answer for this.
Thank you.
Regards
Jay

Hi Jay,
I also have the same question. Why does it work with GET and not for POST?. If you were able to find the answer please let me know.
Thank you.
