Database access with JSP

Hello,
i have a Java Server Page where i fill in some data in a formular. I want to put these data (only two strings) in a database. I already use a servlet to give this data to a (already existing) stateless session bean. I also created and deployed an sda, so that the table exists in the database.
But i do not understand, what to do next - how to use an entity bean to fill the table.
Can anyone give me some hints?
Thanks,
André

Hi Andre,
you need to retrieve the Home Object of your entity bean and use it to create, the same way you create your session bean.
Example:
InitialContext initialContext = new InitialContext();
EjbObject myEjb = null;
try {
java.lang.Object objRef = initialContext.lookup(EjbHome.JNDI_NAME);
EjbHome home = (EjbHome)PortableRemoteObject.narrow(objRef, EjbHome.class);
myEjb = home.create();
} catch (Exception) {
initialContext.close();
The lookup to the home object can vary, you might also have helper classes for that, it depends on your application server, API and architecture.
But however the call or whichever the server, you basically need to retrieve the home object of your entity bean and use the method create() - with any required parameters. Pretty much the same way you create a session bean.
Hope this helps.
regards,
Dionisios

Database access in JSP?

Can I easily access MS access using JSP? If it is, what kind of drive should be used to access the MS Access database?
Thank you so much!

<%!
// define database parameters
String host="localhost";
String user="";
String pass="";
String db="";
String conn;
%>
<%
Class.forName("org.gjt.mm.mysql.Driver");
// create connection string
conn = "jdbc:mysql://" + host + "/" + db + "?user=" + user + "&password=" +
pass;
// pass database parameters to JDBC driver
Connection Conn = DriverManager.getConnection(conn);
// query statement
Statement SQLStatement = Conn.createStatement();
This is when accessing a database in a JSP, not a javabean... Try searching this forum, there are LOTS of topics about this.

How to handle and Manage Multi DataBase access with LCDS in runtime ?

Hello there
I got several customer working with the same application and I wonder how, with LCDS, to manage in a runtime a multi dataBase access; without creating a configuration "mxl" file in
the folder catalina for each database.
Indeed, each customer have their own dataBase, and so far, I did not find out how to avoid creating a config xml file in catalina for every single database; which force me to create as well for each customer a folder application, since the name of the config file in catalina require a folder application to be ran under tomcat....
Thus, my question is :
Is there anyway to create only one configuration mxl file in catalina (in the server side) and then from the client side (application) let the user select its environment (meaning its database) to run the application.... this technic can be also used for multi database environment such as : Dev / Test / Prod environment (or database) where the same application can access to.
Please if any one have an idea or already delt with; just let me know, because I'm entering in a bootle neck and the situation is getting serioulsy critical....
Regards

Hello Ulrich,
with compact and repair I mean the MSAccess function "Compact and Repair".
Please follow the link below for more details:
http://office.microsoft.com/en-us/access-help/compact-and-repair-an-access-file-HP005187449.aspx
Normally you can execute this function directly in Access or with the Windows ODBC Data Sources Administrator => "Control Panel" => "Administrative Tools" => "Data Sources (ODBC)"...
I want to execute this function via cvi code and not by hand ;-).
Thank you for your support.

But after inserted to database, the record in Access was always show "?????" instead of "Thai"......
How can i solve this?
Thank you for your kindness in advances.

It's a pain in the butt, but you'll have to write your own character set conversion to handle the problem. Check out the link shown below (just replace BIG5 in the example with MS874):

Database Access from JSP

I'm trying to access a SQL Server database through an ODBC connection on a JSP page and having difficulties. This is the code that I'm using:
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection("jdbc:odbc:ODBCConnection", "username", "password");
Statement stmt = conn.createStatement();
ResultSet results = stmt.executeQuery(
"SELECT numUserID, txtUsername, txtPassword FROM tblUsers");
while (results.next()) {
int DBuserid = results.getInt("numUserID");
String DBusername = results.getString("txtUsername");
String DBpassword = results.getString("txtPassword");
conn.close();
} catch (Exception exc) {
out.println ("Exception \"" + exc + "\" occured....<br>");
exc.printStackTrace();
I've got two servers I'm testing it on. One is the IBM WebSphere 3.5 on Windows NT 4 and the other one is the Oracle 9i Server (Apache) with java support on Windows 2000. The code works fine on the Oracle server, but does not work on the WebSphere. I am getting a "java.sql.SQLException: [Microsoft][ODBC SQL Server Driver]Client unable to establish connection" exception. The problem is that I need to run this thing on the WebSphere server.
I guess this might have something to do with the Java server differences or OS differences, but I don't know what that could be. I'm sure there's something that I'm not doing right, I just need some help figuring out what that is. I'd appreciate any help anyone can provide. Thanks.

ODBC connection is set up the same on both servers and works with Access. In fact, I have tried to put the same code that I'm trying to use in a regular text java file, it compiled and ran on that same server. I've got a feeling I have the Websphere server setup wrong, but I don't know exactly what and how to fix it.
Thanks.

Sharing Portal database connection with JSP page

Hi out there,
I implemented a JSP page as a selection form to be integrated into Oracle Portal. This JSP page contains a 'dynamic' form which needs to send queries to the database also integrated in the Portal.
For this I am currently using a JDBC connection but I would prefer to use the internal db connection of the Portal System.
Explanation: The user has to log in to the Portal and after that can call the JSP form. To poulate some comboboxes within this form I need some data from the database and the user does have READING privileges on that database.
Can anybody tell me how to use the user's login and password (or the established connection) to fetch the needed data from the database OTHER than with a jdbc connection?
Thanx in advance!
Cheers,
Thomas

sorry. not going to happen. you're running in a completely different environment when running Java on Portal. Portal is running in the database; your Java is running on the application server. your Java code must use JDBC to access any database resources, even if Portal related.
it is essential that you implement a connection pool on the application server to optimize your database traffic. check out bitmechanic for a very good open source option.
good luck,
rich

Database Access from JSP - Is it correct?

From a JSP Page, we need to retreive data from the database. We have our own application specific API commands to retreive data from database. We have doubts in using this API commands.
Approach 1:
From the jsp, send the query details to a Java file (BO). From the java file (BO), call the database and retreive the data
Approach 2:
Use the API command directly from the jsp page to retreive details from the database.
In both approaches, the same API command is going to be used. We just want to know is there any advantage in calling the database through the java file (BO) instead of directly from the jsp?
Regards,
R.Aravinth

Thanks Ram. But we are not going to have any complex
codes written for data retreival. We just epxect a
single line of code which will call database and that
API command will return us a storage variable which
we will use for displaying purpose.
ok take a look at this
//code to display lot of other stuff
<%
    try {
       //code to access db and get data;
    catch(SomeException e){
        //oh-oh you are already on the display logic and have output a lot of stuff
        //how do you handle this
%>versus this
//code in some handler or bean
   try{
           //code to get data
          //set an attribute to enable a redirect to jsp page
    catch(Exception e){
          //handle exception, log ?
          //set an attribute to enable a redirect to error page
Anyways, i wanted to know will the performance of the
page improve if we call the database from a separate
java rather than directly from jsp?As evnafets said, the answer is no. It may even be faster :)
cheers,
ram.

Database access with xslt document

Hello,
I have a big problem. I have a database with three tables and more than hundred records. From the records of these three tables a xml document should be generated. I already have a xslt file which gets the data from the database and brings in a xml form. Is there in BPEL a possibility with the help of a xslt file to access a table? And if so like this is done? Can one give the xslt file in the data bank adaptor? The xslt file has the following appearance:
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:apply-templates select="RESULTSETS/SELECT[@NAME='idoc_element']">
<xsl:with-param name="parent_id" select="'0'"/>
</xsl:apply-templates>
</xsl:template>
<xsl:template match="RESULTSETS/SELECT[@NAME='idoc_element']">
<xsl:param name="parent_id"/>
<xsl:for-each select="ROW[(parent_id=$parent_id)]">
<xsl:variable name="element_name" select="name"/>
<xsl:variable name="element_id" select="id"/>
<xsl:variable name="position" select="position"/>
<xsl:variable name="child" select="/RESULTSETS/SELECT[@NAME='idoc_element']/ROW[(parent_id=$element_id)]"/>
<xsl:element name="{$element_name}">
<xsl:for-each select="/RESULTSETS/SELECT[@NAME='idoc_attribute']/ROW[(element_id=$element_id)]">
<xsl:variable name="attr_name" select="name"/>
<xsl:attribute name="{$attr_name}"><xsl:value-of select="value"/></xsl:attribute>
</xsl:for-each>
<xsl:choose>
<xsl:when test="$child">
<xsl:apply-templates select="/RESULTSETS/SELECT[@NAME='idoc_element']">
<xsl:with-param name="parent_id" select="$element_id"/>
</xsl:apply-templates>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="value"/>
</xsl:otherwise>
</xsl:choose>
</xsl:element>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
This xslt forms a loop about the suitable data and joins them to a xml file.
It would be really great if somebody could help me there.
Thanks
Greeting Cathleen

Hello,
I know that I can define the relations between the tables in the DB Adapter.
But how do I say to him which data he from the tables should get and how should these be joined?
Since my tables are built up as follows:
Table 1 contains the head of the xml document.
Table 2 contains the attributes.
And table 3 contains the real elements of the xml document.
This is, for example, table 3:
Element | Name | Value
/root/E1 | E1
/root/E1/E2 | E2
/root/E1/E2/E21 | E21 | 7777
/root/E1/E2/E22 | E22 | Germany
/root/E1/E3 | E3 | UTIL
And this structure should have afterwards the following construction:
<root>
<E1>
<E2>
<E21>7777</E21>
<E22>Germany</E22>
</E2>
<E3> UTIL </E3>
</E1>
</root>
Besides, subdivide themselves Element2 and Element3 and there is of it more than 100. It is very big xml document at the end.
So a xml file should originate only from the records of the table and I know not at all like I should do this with the DB Adapter. OR as I give in the DB Adapter or where I give it.
It would be really very nice and helpful ones if somebody can help me there. This is since very important for my work.
Thanks

Database access with Jave Web Start

Can a java application, that has been deployed by using Java Web Start, access information from a database that's located on the web server from where the application was deployed?

Yes, if you use the type 4 (ie, thin) driver and include the driver's jar file as part of the app.
Technically you can do it with a thick driver but then you have first install the driver on the client machine and I assume this isn't what you are looking for,

Server side database access with Applets?

Does anyone know how to do this without any JDBC or any other expensive, server heavy and special requirements?
Who could be interested in this?
Am i the only one?
Most internet hosts, rented i mean, do not give many possibilities you have PHP and not much more to access a MySql or other database engine.
If you want to build an aplication, a decent one, you must use java Applet because server side Java is not very interesting and is very expensive.

Personally, I think server-side Java is very interesting and would disagree that a decent web application necessarily requires applets.
I use Supplehost for their reliable and inexpensive Java hosting service.
Many sites and applications make use of cross-browser DHTML and Java server technologies (JSP and servlets) are ideal for building and delivering data-driven DHTML pages.
Of course applets have their advantages but, without a server providing access to data in a database, they're effectively working just as a static web page.
There are other interfaces to databases: for example, Microsoft SQL Server provides the means to interrogate SQL databases through the underlying web server and to have the results returned in XML format.
For me, J2EE provides the best tools for developing data-driven applications and the question over which client should do the presenting is more often one of how best to cater for the intended audience: cross-browser DHTML is best in some circumstances, applets in others, Macromedia Flash in others.
Check out Supplehost's site: you get SSH and secure FTP access to a shared server, can install and run servlets and JSP applications and upload, configure and restart your applications very easily:

Database Access with JspDynpage

Hi,
I want to know if it ist possible to access the WAS Database over JspDynpage.
If yes, can someone post me a tutorial or the way how to do that?
Thanks and Regards,
Dennis

Hi Dennis,
U can create a connection and do datasource lookup and access the database.
InitialContext contx = new InitialContext();
DataSource datasource = (DataSource)contx.lookup("jdbc/SAP<SID>DB");
Connection connection = datasource.getConnection();
Statement stmt = connection.createStatement();
ResultSet rs = stmt.executeQuery("Select * from table");
Also refer to this link for another example.
