Can Java Query An Access Database?

Is it possible to write a Java program that can retrieve data from Microsoft Access tables? If so, how is this accomplished? Are there any tutorials on the subject?

I am not sure about the exact specifics, but what you can do is set up a JDBC-ODBC bridge. What that means is you set up an ODBC DSN for your access database. Then you use sun's jdbcodbc driver to access that ODBC DSN, and they execute normal SQL against that...
Hope that gets you started!

Query MS Access Database

OK - I have a customer that wants to write out to an MS Access Database from Livecycle. I know this is BAD but they have their reasons - i.e. they have a sever shortage of skills for anything more complex.
Firstly - I created a Java program to test the JDBC ODBC connection - this worked fine - ran queries and updated OK (code is attached)
Howver I have tried connecting to Access from within Livecycle in two different ways - both are failing
Firstly - using the JNDI setup for JDBC ODBC e.g.
<datasources>
<local-tx-datasource>
    <jndi-name>MSAccess_DS</jndi-name>
    
    <connection-url>jdbc:odbc:DBFormData</connection-url>
    <driver-class>sun.jdbc.odbc.JdbcOdbcDriver</driver-class>
    <user-name></user-name>
    <password></password>
</local-tx-datasource>
</datasources>
Calling this within a Livecycle process does not return an error to the process, but the log generates an error:
2009-08-29 23:01:30,768 WARN [org.jboss.resource.connectionmanager.JBossManagedConnectionPool] Throwable while attempting to get a new connection: null
org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (java.sql.SQLException: General error)
I also tried creating a Java Component and importing it - by creating a very basic jar and importing it to livecycle (based on the same code I used in my Java testing)
It also gave me the general error - and I can see it is happening on the line:
        Connection con = DriverManager.getConnection(dbURL, "","");
Any ideas on what is going wrong, or a workaround? (Assuming that I have to use Access)
Thanks
Tim

OK I solved this. This was only happening on the Win2K3 server - not on my local dev instance
On the server I set the JBoss service to run under the local admin account (in the Services Panel) - after a service restart the jdbc odbc connection worked fine. It must have been some permissions with the system account

Can Java executes Microsoft Access Macro?

Is there any way to run a Macro of Access database from Java? How to
do it if so?
I searched the internet, I have not found an answer yet. It seems
there is no way. true or false?
We have a lot of statistic charts generated by Macros of either Access
database or Excel and want to put on the web so that user can view the
charts by a click from anywhere. Our web applications are developed
in JSP and on Tomcat.
Any suggestions are appreciated.
Thanks

Insert Image file from java to ms access database

Are there any ways to insert image file or any files into microsoft access database and retrieve the file from the database. Guild will be helpful.Thank you.
regards
Singaravelan

The right answer? Don't do it. You should not be putting images in any database.
Better to write the image to the server's file system and add the path/link to the database instead.

Java visit microsoft access database question

I want to visit microsoft access database,like follows:
String dirverClass="sun.jdbc.odbc.JdbcOdbcDriver"; String url="jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)}; DBQ=C:\\apache-tomcat-5.5.27\\webapps\\Test\\db.mdb"; String content=""; try{ Class.forName(dirverClass); Connection conn=DriverManager.getConnection(url); Statement stmt = conn.createStatement(); String sql="select * from mytab"; ResultSet rs = stmt.executeQuery(sql); while(rs.next()){ content=rs.getString("zd1"); }
My question is whether I must install microsoft access database?
Thanks

Far as I know and have been able to determine a MS Access ODBC driver comes with every windows install going back to about windows 98. Might be 95 as well.
I haven't looked at some of the more exotic ones like the 64 bit versions nor the mobile versions.

Cannot connect and run query for Access database

Hi,
I have a html file and a servlet file which contains code to connect to a database. I also have a sales database with customer table along with other tables in Access. I have created a DSN in Windows named sales which connects to the sales database. Now, when I am running the html form, the servlet does not run the query "Select * from Customer". It seems it cannot make any connection to the database.
Any help is appreciated. I am very new to JDBC technology. Thanks.
HTML FORM CODE:
<html>
<head><title>Sales</title></head>
<body>
<form action="http://localhost:8100/servlet/SalesServlet" method=POST>
<strong>Select:</strong>
<textarea cols=50 rows=8 name=select></textarea><p>
<input type=submit value="Query">
<input type=reset>
</form></body></html>
SALESSERVLET CODE:
//Copyright (c) 2000, Art Gittleman
//This example is provided WITHOUT ANY WARRANTY either expressed or implied.
/* Queries the Sales database. Needs to be modified
* to use metadata to correctly output the result set.
import java.io.*;

import javax.servlet.http.*;
import java.sql.*;
import sun.jdbc.odbc.JdbcOdbcDriver;
public class SalesServlet extends HttpServlet {
Connection con;
Statement stmt;
public void init(ServletConfig sc) throws ServletException {
super.init(sc);
try{
new JdbcOdbcDriver();
String url = "jdbc:odbc:Sales";
String user = "";
String password = "";
con = DriverManager.getConnection(url, user, password);
stmt = con.createStatement();
}catch (Exception e) {
e.printStackTrace();
System.exit(1);
public void doGet(HttpServletRequest req,
HttpServletResponse resp)
throws ServletException, IOException {
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();

ResultSet rs = stmt.executeQuery(query);
ResultSetMetaData rsMetaData = rs.getMetaData();
int cols = rsMetaData.getColumnCount();
while(rs.next()) {
String s = "";
for(int i=1; i<=cols; i++)
s += rs.getString(i) + ' ';
s += "<br>";
out.println(s);
}catch(Exception e) {
e.printStackTrace();
out.close();
public void doPost(HttpServletRequest req,
HttpServletResponse resp)
throws ServletException, IOException {
doGet(req,resp);
}

String url = "jdbc:odbc:Sales";
String user = "";
String password = "";
con = DriverManager.getConnection(url, user, password);This might be causing your problem, but not sure. Since you don't need a username or password for the ODBC connection, you can just use
con = DriverManager.getConnection(url);
The username and password aren't needed, so you can just use the above call instead. Perhaps the ODBC is trying to find a user called "" with a password "" and puking on itself, who knows... but you should post whatever exceptions or specific problems you're having that make you think you're not connecting.

Using normal java classes to access database

Dear friends,
Is it a good practice to make database calls from a normal java class within J2EE environment.
What I meant by a normal java class is a class which is not an enterprise bean.
Best Regards,
Chamal.

it is quite normal.
If you make your own DAOs, it may not be efficient/generic.
JSP/Servlets can use Hibernate (which is a set of POJOs) to access DB. Thus you have a J2EE environment using a very matured DB access methodoloy, and doing away with Enterprise bean.

SQL Query with MS-Access Database

Hi,
I have linked my oracle database with MS-Access via a DB LINK. i can access the data from MS-ACCESS, but i have a problem that when i specify the column name or define a where clause in my query it gives me the error ORA-00904: invalid identfier ..
This query fetch the data without any problem SELECT * FROM TBLREPORT@M_ACCESS but when i run SELECT EMP_ID FROM TBLREPORT@M_ACCESS it gives me the error i mentioned above. (Column name have No problem or mistake of spelling even CASE)
also when i try to put where clause in the query it gives me same error SELECT * FROM TBLREPORT@M_ACCESS WHERE EMP_ID = '100' (Error)
is there any change in SQL query for ACCESS database ??
any clue
Regards
Rehman

Are column/table names in access case sensitive? Issue
DESC TBLREPORT@M_ACCESS If column EMP_ID actual name shows up in mixed/lower case, enclose it in double quotes and use the exact case. E.g., if column name shows up as Emp_Id, use:
SELECT "Emp_Id" FROM TBLREPORT@M_ACCESSSY.

Java, access database( mdb) and java.sql.date

I having a problem querying my access database with user specified date the code is as follows
//get results of income from database with respectto dates
     //so u first create the sql.date instances
     private void getResults(){
     String text1=from.getText();//text input is like this 01-01-2005
          String text2=to.getText();
     Date d1=new Date(Integer.parseInt(text1.substring(6)),Integer.parseInt(text1.substring(3,5)),Integer.parseInt(text1.substring(0,2)));
     JOptionPane.showMessageDialog(this,d1.toString());//traces date with 1900 added to year and 1 added to month
     try{
          //custom class DataSource used to connect to database
          Connection conn=DataSource.getConnection("RealFotoInc");
          PreparedStatement ps=conn.prepareStatement("select * from Members where date=?");
          ps.setDate(1,d1);
          ResultSet rs=ps.executeQuery();
          while(rs.next()){
               System.out.println("going");
               System.out.println("trial"+rs.getString(3));
     }catch(Exception se){
          JOptionPane.showMessageDialog(this,se);
     }and it prints out nothing I dont know what is wrong

Whoever put that comment in there about "1900" and so on knew what had to be done. That "Date" class must be "java.sql.Date"; go and read the API documentation of that constructor you are using there. Then adjust the parameters you are passing to it accordingly.

[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.

Connecting to an Microsoft Access database

Can I create an HTML page or equivalent from which I can connect to an Access database that is on my computer or a drive connected to the computer WITHOUT having my computer run a server application? I have read the online help and not sure if I can do it and what has to be done.
The goal is to create a Web page that is an interface to an Access database that resides on a shared drive that anyone in the company can map to. I realize that the Web page connects using an ODBC driver, but does the user's computer also need to be running some kind of server application?
If it can be done without a server application, how do I set up the testing server, etc.
Thanks,
Van

No, you will need an application server like ASP, PHP or ColdFusion to display dynamic data from a database.

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 database query resultset in java scriptlet

Question:
1) I am Creating a web page and plotting points on the page:
2) Database query results in decimal values dec_latitude and dec_longiitude.
3) Perform calculations on lati. & long. in a java scriptlet to create a plot position (xpos, ypos).
4) Send the xpos and ypos back to the java server page
5) Use <IMG and absolute positioning to plot the point at position xpos, and ypos.
6) Repeat until all rows in the query result set have been plotted.
I don't know how to pass the dec_latitude and dec_longitude to the java scriptlet.
After the java scriptlet calculation translates the latitude and longitude
into xpos and ypos, I need to pass the xpos and ypos back to the java server page so that a data point is plotted on a map at position xpos, ypos.
I tried many ways of doing it but am just guessing as
to how to pass the data.
Thanks in Advance. - John
Here is what I am trying so far .... see snippet below:
The code below results in a runtime error.
Am I supposed to create a java object and access that in the java scriptlet? Can the java scriptlet access the latvar and longvar created during the "<c:set var="latvar"... ?
If not, what mechanisum do I use to access the resulting colums: dec_latitude and dec_longitude? I need the java scriptlet to convert the
dec_latitude and dec_longitude into a display position based on the number of pixels from the TOP and LEFT (xpos, ypos). Then plot of the data point using the IMG and (xpos, ypos). This will overlay a map whose z-index is lower than the plotted data point.

ypos = (int)Math.round(longitude);
xpos = 1082 - xpos;
ypos = 700 + ypos;
pageContext.setAttribute("xpos", xpos);
pageContext.setAttribute("ypos", ypos);

Thanks
I still get a runtime error: I translated the code you gave to code below .... which I think is equivalent. See Below: I'm still learning about this stuff so I may not have not translated this properly. Do
you see what I am doing wrong?

How to connect with Microsoft Access Database with JAVA

I want to know the command and query to connect between MSAccess and JDBC.
Is it beter way to make connection with MSAccess comparing with other Databases such as SQL and Oracle.
Which Database will be the best with Java?
I also want to know to be platform indepadent which database is suitable?

On Windows, you can use MS Access database by:
Set up a System Data Source using the ODBC control panel applet.
Use the jdbc:odbc bridge JDBC driver, and specify a jdbc url that points to the data source name you just specified.
It's been too long since I've done this, so I don't remember the syntax of the jdbc url, but I'm sure that if you do a search for the jdbc:odbc bridge that you will find what you are looking for.
As far as the question about which database is best, you will need to determine that based on your project requirements.
If you want a quick and dirty, open source, cross-platform database, take a look at HyperSonic SQL.

Berkeley DB Java Edition - multiple threads accessing database

Hi,
I would like to access (read & write) a Berkeley DB from multiple threads (all same process/jvm).
Should I use a single com.sleepycat.je.Database object for all threads, or should I create an instance for each?
Or is there any other way of doing it?
Thanks

The Database object may be used by multiple threads, so you can use a single instance or multiple ones, as best suits you. From http://docs.oracle.com/cd/E17277_02/html/java/com/sleepycat/je/Database.html,
Database handles are free-threaded and may be used concurrently by multiple threads. 'If you read through the javadoc, you'll find other notes on using classes from multiple threads.
Regards,
Linda
