Accessing database from VBean

My adventures in vbean-land continues:
Is there a way to access the database connection of the forms process from somewhere in the VBean/IHandler contexts?

I'm searching for a long time a way to extract the data from a BLOB, then transfert it to a Bean, via Forms Set_Custom_Property() to share the standard Forms connection. I'm trying to use the Base64 encoding to transfert the chunks of data from database to the bean,but, with images, some characters are misinterpreted. Don't know why but the image is corrupted and the result is unreadable.
If you can find something, I will take !

[JDBC][ODBC] How to compact access database from Java ?

Hello,
I'm developping a java applcation wich is connected to an MS Access file database.
For now, I don'y compact it but it would be better.
So How can I compact an access database from Java ?
thanks :)

Hi ypiel,
Try this:
1) Download JETCOMP.exe (freeware from Microsoft);
2) Put the following code in your app (assuming your database file name is: "DB.mdb"):
try {
File current = new File("DB.mdb");
File backup = new File("BACKUP.mdb");
if (current.renameTo(backup)) {
Runtime.getRuntime().exec("jetcomp -src:BACKUP.mdb -dest:DB.mdb");
} catch (Exception e) {
System.out.println(e.getMessage());
Best regards,
YT.

Please help me in accessing database from URl

hello can i please access database of yohoo messenger's online IDs from specific chat rooms e.g. regional, romance, programming etc.

Unless yahoo is terribly stupid, which I don't think they are, there is absolutely no way that you are going to access any database of theirs.
If you actually want a list that represents something on yahoo then your choices are:
-Ask yahoo for a page that displays it.
-Search yahoo to find the page yourself.
-Write a screen scaper that calls one or more pages and constructs the relevant data yourself.
If none of the above answers the question you are asking then please add more detail to make it more understandable.

How can I access database from FORMS 6i?

Dear co-developers,
I am new to developing and just installed Oracle forms 6i but when i try to access my database schema tables from forms 6i I get TNS error saying it could not resolve the service name. I need help in two things:
1. I wanna know how to (and where to) make appropriate change in TNSnames.ora file or any other file to make things work.(I request u to explain in detail)
2. what is the concept of oracle homes? Oracle forms 6i takes a new oracle home. And Oracle 9i Database takes another home.
I have Oracle 9i Release 2 installed on windows XP pro.
Thanx in advance and looking for a quick response.
Mukesh

hi there,
i wanted to know from you that are you able to access your database from sql*plus?,if yes then i will give you the step by step info on how to configure your tnsnames.ora file automatically or manually.
Automatic step
1.Open net 8 easy config from start menu under programs where ur forms application shortcuts are installed.
2.if the net 8 easy config doesnt open make a windows search for the file name symcjit.dll if the file is found rename it to any other name.
3.if after renaming the file still you are not able to open it then you have to go by the manual way.which is concluded next
4.now you have to add the database alias here.click on the add service and press next.
5.provide your database name here in the service name text box.dont change the port number leave as it is.
6.now again give your database in the sid text field.
7.hit next and test you connection with scott/tiger or any other user.
8.if the test is succesfull exit the configurator and test you forms for connectivity.
first try this if nothing happens i'll post the manual method.

Query 32 bit Access Database from 64 bit Sql Server

Hi All,
I have a task to query the Accessdb from Sql Server and below are the configuration details:
OS: Windows Server 2008 R2 Enterprise( 64 bit)
Sql Server: Sql Server 2012 enterprise (64 Bit)
Access : MS Office 2010 (32 bit)
I used the below queries to reap the data from access db.
SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0','D:\Product.accdb', Product) AS Product
(or)
SELECT * FROM OPENROWSET('MICROSOFT.ACE.OLEDB.12.0','D:\PRODUCT.ACCDB', PRODUCT) AS PRODUCT
following error returnd from both queries.
Error: "Msg 7438, Level 16, State 1, Line 2. The
32-bit OLE DB provider "Microsoft.Jet.OLEDB.4.0" cannot be loaded in-process on a 64-bit SQL Server."
Please help.
Ram MSBI Developer

not sure if anyone is watching this thread anymore but i have this scenario. i am using the excel connection manager in SSIS to create an excel spreadsheet with VS 2012. To do this from what I have read I am required to use the 32-bit driver for "Microsoft
Access database engine 2007", if I use the 64-bit driver I cannot connect to the Excel connection manager. i get 0xc020801c message.
i can install the 32-bit "Microsoft Access database engine 2007" and resolve this problem. but i also have a stored procedure that creates a spreadsheet (i use this because i have to leave some cells intact), it appears to require the
64-bit "Microsoft Access database engine 2007". in 32-bit mode i get the following message
Msg 7438, Level 16, State 1, Procedure sp_CreateGRfile, Line 26
The 32-bit OLE DB provider "Microsoft.ACE.OLEDB.12.0" cannot be loaded in-process on a 64-bit SQL Server.
so i need both the 32-bit "Microsoft Access database engine 2007" and 64-bit "Microsoft Access database engine 2007".
any thoughts on getting around this issue?

Open an Access database from ASP on the Windows 2008 32-bit server

We are upgrading to a Windows 2008 server. The ASP application opens an Access database with this code:
Set oConn=Server.CreateObject("ADODB.connection")
  oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=E:\webdata\applications\po\sfisnet\sfisnet.mdb;"
The open statement causes this error:

Research includes:
- ODBC drivers
- verified that the ms jet dll is present: msjet40.dll, msjet35.dll
- IIS settings reviewed
- permission and sharing on the directory and "sfisnet.mdb" database
- verifies thet OLEDB_SERVICES is in the registry

Writing a table to a MS Access database from Powershell

Hey guys, me again...I'm trying to wrap up a project here and i have a powershell app writing to a SQL database just fine. The last piece is writing to a MS Access database table. For the life of me i cannot find anything out there that really points me
in the right direction.
I know my database name/path and i know the table/headers i need to write my data too.
Anyone have a link to a quick dirty tutorial or can someone point me in the right direction ?
Thanks as always
Rich
Rich Thompson

I get no error message. I created a blank database with a table called dbo_so_shprimg_pvs and headers
called so_hdr_key, so_ship_key, imgfileName, so_shprimg_crtdt. I'm doing a test write-host
prior so i know my variables are good.

Problem accessing database from JApplet

Hi all,
I am having trouble in changing my application to Japplet. It displaying the frame in web page but when i am trying to access database it is not displaying anything. Please let me know if any one know the solution. Thank you.
bestpro.

It is hard to say since you didn't post any exceptions you are getting but I would venture to guess you are getting a security exception and you need to sign your applet so your applet can play outside of the security sandbox and connect to your db server.
Hit google and search for "signing applets" or something similiar and it should put you on the right path.

Not able to access database from a remote machine using SQL Server Management Studio

I have a DB_BOX with SQL Server 2008 R2 installed. I can access the databases on the local machine using SQL Server Management Studio but it is not accessible from other machines, though the machines are in same domain.

Sorry, missed the message from the errorlog in the original post. You shouldn't have included that big .Net dump that hid the important facts. :-)
My first Google attempt on that message (which I have never seen before) suggests that the TCP Enpoint is stopped, so try this:
ALTER ENDPOINT [TSQL Default TCP]
STATE=STARTED;

How to access database from applet using connection pooling.

Hi,
I am using tomcat 4.1, JRE 1.4.2_10, MySQL 5.0, and IE 6.0. I can access the database using connection pooling from JSP without problems. But, if I try to acess from the applet, I get the following exception (related to JNDI.):
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.lookup(Unknown Source)
I know what this acception means, but I don't know how to fix it. I set up connection pooling in my Tomcat 4.1 that talks to MySQL 5.0. As I said, when I access from jsp, JNDI works. But, applet complains. Please help. In my applet, the following code accesses the database:
ArrayList toolTipData =
      access.getToolTipData (projectName,interfac);This is the snipet of my Access class:
public ArrayList getToolTipData (String projectName, String interfac) {
    System.out.println("In getToolTipData");
    ArrayList toolTipData = new ArrayList();
   try{
    Context ctx = new InitialContext();
    if(ctx == null )
        throw new Exception("No Context");
    DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/interfacesDB");
    if (ds != null) {
      Connection conn = ds.getConnection();
      if(conn != null) {

The jsp runs on the server, whereas the applet runs on the client so
you must package with your applet any jndi implementation specific classes
and
Properties props = new Properties();
props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory" );
props.setProperty("java.naming.provider.url", "url:1099");
Context ctx = new InitialContext(props);
Object ref = ctx.lookup("...");

Accessing database from an applet

Hi
I'm trying to access the database (MS Access) using type 1 driver sun.jdbc.odbc.JdbcOdbcDriver from an applet client. It works fine with the java application and also using appletviewer after creating a policy file and ran using appletviewer -J-Djava.security.policy=testpolicy.policy Output.htm
But when i try to run through the applet, it throws the exception as
java.security.AccessException
Pls help me,
Thansk
L-m-t

There is another way of doing it. That is to sign the applet (or the applet jar-file). That way the browser displays a dialog to the user so he can press yes, to grant all permissions. I have not found a way (via a dialog) to let the user grant only the permissions you need for the database connection.
