Applet good to access database though web???

Hi,
I have a java3d applet which I must link to a database. And later the applet has to be accessible from a laptop not necessarily connected to the local network.
I am quite new in this area ... as you might have guessed !
First, do I have to use servlets ? Is it more or less works like php?
Could someone give me a hint on the overall architecture of the system ? Any suggestions ?
What I have in mind is a 3 tier application. For example Web server + Oracle server and the client connects to the web server.
Hope someone can give me some ideas or suggestions.
Thanks

Use an applet if you must. I'd prefer a JSP that used JSTL.
I think a servlet is a good gateway to that database. Let the JSP simply present results to the client. POST requests to the servlet, which interacts with the database on the user's behalf and sends results back to the JSP.

I want to connect an applet with an access database

I want to connect an applet with an access(*.mdb) database, how I do?
I now the jdbc odbc bridge but how work it?
Please Help me!!!!!!!!!!

If you want access database please install IDSSERVER and import j102.sql.*;
Example:
import java.awt.*;
import java.io.*;
import j102.sql.*;
public class AccessMdb extends Applets {
Connection con;
ResultSet rs;
Statement stmt;
IDSDriver drv;
String _url ="jdbc:ids://localhost:your port /conn?dsn="your database"";
// make connection to database
drv = new j102.sql.IDSDriver();
try{
con = drv.connect(_url,null);
stmt = con.createStatement();
// query database
stmt.executeQuery("your SQL statement");
}catch(Exception ex){
System.out.println(ex.getMessage());
Good luck.

How to administer an Access database via web-based interface?

There are times when I need to edit a database record to do something my CMS wasn't designed to do, so I have to manually edit it. Normally I just ftp the Access mdb file to my pc, make edits, and reupload the mdb file and hope nobody updated the database in the meantime. Does anyone know of a web-based database admin system that will allow me to edit Access data? Sure would be nice if I could install something on the server that would allow me to edit any datasource there and not have to have a separate, customized interface for each datasource.
Thanks for looking, Bill

I would recommend naming that page with an extension that the web server will not serve. Rename it to use it and then rename it back when done.
Or just put access restrictions on it via the web server, so one needs to authenticate to the system before using it.
Or stop using Access and use a decent DB: Access is not appropriate to be used as a DB for a web application. But that might not be an option.

Migrating Access Database to Web WITH FORMS (not just backend)

How difficult would this be, what steps would be involved and is Dreamweaver capable of helping?
The server uses IIS and ASP so compatibility should be fine with access.
I have enough of a programming history to replace vbasic code with ASP code if I read about the language, but would like to do the least amount of work required.

Lets just say that Access and Oracle are completly different animals and leave it at that. What I believe you need to do is:
1. Create an Oracle Database using the Database Creation Assistant. (Keep all the Defaults, and keep track of any passwords that are used.
2. Using the System (DBA) account, crate a user to hold the Access Schema (Never create objects in the SYS account and you shouldn't do that with the SYSTEM account either.
3. Run the Access Migration Workbench.

Using JavaScript to access Database

Hi all,
I am using JSP and Tomcat for my web application.
Now i need to use Javascript to access the MS Access database. Can anyone please tell me the class and command for accessing database from javascript.
Please give me an example and that will help me. I know it is not good to access database using JavaScript. But in this situation i have to use it anyhow.
Thatnks

Hi all,
Thanks very much for your help. Now some of you said that it is not possible in JSP to access database using JavaScript, some of you said yes it is possible but not secure, I understand the both concepts.
Now my problem is last year i built a web application for my company and the scenario is like this:
The staff records their working time in that application. Now when they click a button it creates a drop down list of all clients they have and that list is in HTML as SELECT TAG. So the select tag includes 100+ client name.
Now they can add as many client as they want for example if i have worked with 10 clients i will create 10 drop down list by pressing button called ADD CLIENT and will record their hours.
Now from the description above you guys can understand that an OnClick Javascript event in involved to create multiple dropdown list.
Now what i want is that i want those 100+ client list to come from database rather than typing them in the SELECT TAG. and please remember the SELECT tag is implemented in Javascript using innerHTML event.
Now for those of you who suggested that it is not possible to use Javascript in accessing database, can you please tell me how can i implement Onclick event using JSP/Serverlet and can create dynamic drop downlist?
Thanks for your time to read this long message.

Access Reliability in Web Application

Does anyone have recommendation on using Access database in
Web application.
I have always used Access, but recently heard that it can
cause great problems if more than one user is accessing information
at the same time.
Is there anyway around this or do I need to switch to MySql?
The application is written entirely within Coldfusion, using
a DSN for the Access DB.
This is a small application and it would be rare that more
than one user would be into the same table at one time but it could
happen, as there is a login and the users table would be accessed
each time someone logs in.
Any insight would be helpful. I really don't want to have to
redo the database.
so far there have been no problems but I would be in a fix if
the system crashed.
Thanks.

think it would be to migrate to MySQL from Access?
Anyone have experience with this?
Thanks!
The work might not be hard, but there is an awful lot of it.
I changed one from Access to Oracle once. What I did was:
1. Create the Oracle tables and sequences.
2. Transfer the existing data to the new db.
3. Test every single query and rewrite the ones that needed
it.
So far there is no disruption to your production app, until
now.
4. Take the production app offline to freeze the data.
5. Bring the new db up to date.
6. Put your new app into production.

Does anyone have a good link for images I can access for my web development work. I have Adobe Creative SUite 5.5

Does anyone have a good link for images I can access for my web development work. I have Adobe Creative Suite 5.5

In short, NO.
I was hoping that the 7.4.1 update would allow it to work, but it has caused more problems than it is worth.If you do actually get it to work you will see the TC in finder (under Shared) when connected to the internet outside of your home network. What I have found though is that the 7.4.1 firmware update has made using the internet at home almost impossible.
I have tried Hamachi but it is not reliable.
I have settled with Dropbox so my files are synced between my home machine and laptop.

Applet and Access Database

How can I use an Access Database with a web applet? I can do it on my machine because I can set the data source. However, I can't set the data source on the server I'm uploading my web page to. Suggestions?

You may be able to find some third party vendor that wrote a JDBC driver for Access that allows you to connect directly, but I doubt you'll find one.
I don't know what you are needing to do exactly, but have you considered using an XML file?

Access of ms access database and displaying it on applets

I had made the connection thru JDBC and was able to access data from MS Access database when i had written java application program. But when i created one applet and created instance of that class which was making connection to the database thru JDBC and called one method which was returning one value from the database , i was not able to get on the applet(in the text field) . It gave me some security exception saying acces is not allowed.
Please give me the reason for this and send me reply back on this email id

SetDataSource not working for Web App Access database

I have a web app developed using VS 2008 that is using Crystal Reports to produce bar graphs. The data is held in an Access database. I developed the report using an Access database located in the App_Data directory.
I have the following code on the page load event.
   Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim con As New OleDb.OleDbConnection
        con.ConnectionString = System.Web.Configuration.WebConfigurationManager.ConnectionStrings("strConnect").ToString
        Dim path1 As String = "|DataDirectory|\ForthWorthISD.mdb"
        Dim report As CrystalDecisions.CrystalReports.Engine.ReportDocument = New BuildingUsage
        report.Load(Server.MapPath("BuildingUsage.rpt"))
        Dim com As New OleDb.OleDbCommand
        com.CommandType = CommandType.Text
        com.CommandText = "SELECT * FROM tblFWISDBuildingUsage WHERE BuildingName = '" & Session("BuildingName") & "'"
        com.Connection = con
        Dim adp As New OleDb.OleDbDataAdapter
        adp.SelectCommand = com
        Dim ds As New Data.DataSet
        Dim result As Integer = adp.Fill(ds)
        Try
            report.SetDataSource(ds)
        Catch ex As Exception
            Dim fubar As String = "Fubar"
        End Try
        Label2.Text = Session("BuildingName") & "      Monthy kWh"
        Label3.Text = "January 2006 Thru December 2008"
        CrystalReportViewer1.ReportSource = report
    End Sub
I have checked the DataSet after the fill and everything appears to be correct. There is only one row in the table
However the report is showing the entire table.
I have also tried setting the datasource to the datatable of the dataset with the same result.
How can I get this to work?

Hi Bob,
You stated that you designed the report against the access database itself correct?
Are there usenames and passwords required to access the db?
What looks like is happening is if you designed the report against the database instead of against an xsd file (which if you are using datasets should be done) then it has the access info stored so just hits it and pulls all the data.
Try outputting the schema of the dataset and do a set location in the designer to the xsd instead of the access db then try passing the dataset.

Web-Intelligence Reports against Access Database

We are unable to run Web-Intelligence reports against Microsoft Access Database which resides on a network drive
Able to create Unvierse, and Universe Connection to the Access Database through ODBC, but unable to run Web-I reports, when tried we get the following error
A database error occured. The database error text is: [Microsoft][ODBC Microsoft Access Driver] '(unknown)' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.. (WIS 10901)
Did anyone tried to develop Web-I reports from Access database on a network drive, if so I request you to provide us details and your findings
Thank you

We run the designer on the same machine where BOBJ runs and also on other client machines, from disigner it works fine,
The service account which is used to run BO Application Services has full control access to the network location and folder where the database resides
We can run / refresh Desk-I and Web-I rich client but cannot run web-i reports against access database

MS Access Database on Runtime (Tables on Sharepoint)

Using: Office 365
MS Access tables are on my Share Point Site as lists.
The database on my local pc has linked tables to the Share Point lists, which works fantastic. I have a need to place the database on a pc that does not have any office software installed, so I loaded Access Runtime on that pc. Pulls up the database,
but, it the tables will not link to Share Point. No error messages, cursor just spins, nothing happens.

Actually I'm already using JDBC-ODBC driver. The problem is it still doesn't connect. Sorry I should have mentioned this above.
String dbDriver = "sun.jdbc.odbc.JdbcOdbcDriver";
String dbLocation = "//host/directory/database.mdb";
String dbURL = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)}; DBQ=" + dbLocation;
String dbUserName = "Name";
String dbPassword = "Pass";
public boolean connectToDatabase () {
// Microsoft Access Database SQL Connection.
try {
    Class.forName(dbDriver);
    connection = DriverManager.getConnection(dbURL);
} catch (Exception e) {
      return false;
return true;
}If I run my applet local, I can connect to my Access DB (Using a location similar to 'C:\Path\myDB.mdb'). When I put it on my web host, it can't connect to it. DriverManager tries to connect but fails after about half a minute of inactivity. The error message is:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] '(unknown)' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.
And so I need to know any Java equivalent that doesn't require 'HttpServlet' 'getRealPath(...)' and get's me the server path to my DB or another way to connect to it alltogether.

Access database in a WAN

Hello:
I have to develop an application in Director that will use
one Access
Database in two LAN in different cities.
So I will need to connect these LAN's via Internet. (10 users
in every LAN
with XP client)
Do you think DatagripNet is OK for this purpose or do you
suggest me other
third party software?
thank you

> This link does not work :
http://www.shocknet.org.uk/
You're right. I have seen it being down before. Give it some
time - it will
hopefully be back.
> Well I am most confused now. I don't know program in PHP
or ASP. This can
> not do it with Lingo?.
When shocknet.org.uk is back, you'll see that - besides very
good tutorials
in all the net stuff - there is a collection of scripts,
prepared for your
situation.
1. A lingo behaviour to send a postNetText call to the
ASP/PHP script on
the server where your database is.
2. PHP/ASP script (depending of what the server supports - so
your choice):
The script does the following:
- recieve the call from your application
- send a query to the database
- process the result into a lingostring
- and then return that string back to your application
As far as I remember, all you have to do in the PHP/ASP
script is:
- add the correct connectionstring to the database.
- specify the SQL string that corresponds with your needs
(select, insert,
update and so)
> How to use SQL server with Director? some Xtras?
The princip above will work for most kinds of databases,
Access, MySQL and
MSSQL for sure, meaning that you can change database, but
keep the PHP/ASP
script.
You'll have to change the connectionstring to the right one
though.
There are SQL xtras, but I have ony experience in working
with them locally
(LAN)
I'll repost this fine line from Andrew - it says somehow the
same as my 20
lines above...:
[Your program]<->[Internet]<->[CGI program or ASP
or PHP]<->[Database]
If you are lost, then try to get help for the serverside, so
you can
concentrate on your application.
