Access Initialization Parameters using jsp

Hi All,
Now I'm learning JSP . I want to access the initialization parameters using jsp. How to do it. I used the following code , but it shows null
initparameter.jsp
    <html>
     <body>
          <h1>
               <%
                    out.println("InitParameter Checking");
                    out.println(application.getInitParameter("param1"));
               %>
          </h1>
     </body>
</html>I configured the following tags in my web.xml.
        <servlet>
          <servlet-name>initparameter</servlet-name>
          <jsp-file>/initparameter.jsp</jsp-file>
        <init-param>
                <param-name>param1</param-name>
                <param-value>value1</param-value>
            </init-param>
     </servlet>
                Help me to resolve this problem
Thanks in advance,
mahes

try overriding the jspInit method and then call getServletConfig() method and call getInitiParameter() on that ..infact the config implicit object would iachieve the same .i don't understand why it's printing null in your case .let me test and see

Initialization Parameters for JSPs ??

Hi All,
          Is there any way to provide Initialization Parameters for JSP ??
          If so how should it be done on Weblogic ??
          Thanx In Advance,
          Navaneeth.


Hi Navaneeth ,
          If we want to provide Initialization parameters for jsp , we need to register a JSP as a servlet using the <servlet> element.
          Registering a JSP as a servlet allows you to specify the load order, initialization attributes, and security roles for a JSP, just as you would for a servlet.
          <servlet>
          <servlet-name>MainServlet</servlet-name>
          <jsp-file>/myapplication/critical.jsp</jsp-file>
          <init-param>
          <param-name>Name of the Parameter</param-name>
          <param-value>Value of the Parameter</param-value>
          </init-param>
          </servlet>
          go through the link ,you will find the documentaion on this

That's the code that you need to execute but you should
probably encapsulate that code in Custom Action.
Orion has a EJB Tag Library that is free to distribute that
does all that stuff you just set some attributes.
Go to their site and look at their Tag Libraries.
Also look for other Tag Libraries Freely Available for EJB Access.

Uploading images in access database using jsp

Hi, am using jsp with access database and want to upload as in a profile picture for any profile on the site[i mean depending on the user's convenience] ..
I just have a code which helps select the image from the client's machine n gets its address..but then how to use it in a form or something so that it can be submitted and inserted in the database?
Any idea? I d prefer not using servelet.. but if it just cannot be done without servelet then ok can suggest with that too.
Here is the code of Browsing to obtain the picture:
<form name=uploadForm action="uploadpic.jsp" method=post enctype="multipart/form-data" > <input type="file" > <input type="submit" name="submit" /> </form>

bad. Don't put business logic in JSP, and that includes accessing databases.

Don't put business logic in JSP. That's what servlets are for (and EJB).

Need sysdba access to edit initialization parameters

When I log into enterprise manager, go to database, then initialization parameters..
it says 'You are not logged on with sysdba privilege'
my preferences - credentials has sys and password in the sysdba fields..
what needs to be done

What you need to do is logout, and log back in with a user that has sysdba privileges.
After you click on Logout, you will see the options:
- Log out of Database: database_name
- Display database login page after logout
Use this option to reconnect to the database as a different user
Log out of Enterprise Manager and all other targets
(Logged in As YOURUSER)
Select - Log out of Database and Display database login page after logout.
You will then get the option to connect as sysdba. Change Connect as "Normal" to SYSDBA.

Cannot access VARCHAR2s on Oracle 9i using JSP/JDBC

After upgrading from Oracle 8.1.7 to Oracle 9, I get an
exception when using JSP/JDBC to read data from columns
containing VARCHAR2s. I can successfully read columns
containing BLOBs, CLOBs, NUMBERs, and RAWs.
I still can select VARCHAR2 columns by using SQL*Plus so the
problem is with JDBC and not the database.
I get the following exception message:
java.sql.SQLException: ORA-00600: internal error code,
arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []
The following code that worked on Oracle 8 fails to execute
properly on Oracle 9:
OracleResultSet rs = null;
String sql = "select name from users where id > 100";
rs = (OracleResultSet)s.executeQuery(sql);
I'm using Windows 2000, Tomcat 3.2.2, Java 1.3, and the latest
version of OracleJSP.
Has anyone run into this problem?
I've also entered this same query on the Java-SQLJ/JDBC
discussion fourm.

I4ve installed Oracle 9i on RedHat 7.2.
We develop with WebObjects and JBuilder.
When i try to connect to the database via the EOModeller (JDBC) i got the same error:
Stack Trace:
JDBCAdaptorException: ORA-00600: Interner Fehlercode, Argumente: [ttcgcshnd-1], [0], [], [], [], [], [], []
Then, i started creating and droping tables in the 9i Database >> it works fine.
Can someone give an solution for this problem??

Using jsp in webi(BO).

How can i use Jsp in BusinessObjects Webintelligence tool and for what purpose i can use jsp coding to create reports?
Thanks in advance.

Hi Meghna,
Did you try this query in repository explorer?
This seems very complex query and as per error some mandatory initialization is missing
I guess each valuation have their own identifier, which you also have to pass as parameter.
Give a try in Repository explorer with all required parameters.

File upload and download using jsp/servlets

How to upload any file to the server using jsp/servlets. . Help me out

You can also try the Jenkov HTTP Multipart File Upload. It's a servlet filter that is easy to add to your web-project. After adding it, you can access both request parameters and the uploaded files easily. It's more transparent than Apache Commons File Upload. There is sufficient documentation to get you started, and there is a forum if you have any questions.
Jenkov HTTP Multipart File Upload is available under the Apache license, meaning its free to use.

Accessing Portal session in JSP

Hi
How can I access session parameters set via wwsto_api_session in jsp portlet.
Regards,
Vikas.

Hi,
If you want to access the procedures in wwsto_api_session package from a JSP, you can use JDBC calls.
Otherwise, if you need the Httpsession specific information you can use the ProviderSession class in JPDK. You can obtain an instance of this using PortletRenderRequest object.
thanks,

Can I access URL parameters?

Is it possible to access URL parameters from a WebStart application?
Example:
http://www.domain.com/example.jnlp?parameter1=43
I would like to initialize my JWS app using the information given to me in parameter1.
Is this possible? I believe that this would be very powerful.
Thanks.

If your www.domain.com/example.jnlp is a CGI script or servlet that returns a .jnlp file with
<application-desc>
<argument>43</argument>
</application-desc>and you retrieve that parameter from args[1], it might work.
Regards,
Marc
