How to call java class file from jsp

hi
we need to call java classes (which are written separately in .java file )from jsp file. we need it for our project if anyone knows about please reply us.
bye
siva sankari

you can call the methods in a lot of ways. you could use scriptlets with the
<%@ page import="package.class"%> and then inside instantiate an object
<%
MyClass mc = new MyClass(parameters if any);
mc.theMethodYouWantToCall();
%>or as Madathil has stated,
or use the JSP tags
<jsp:useBean id="anyname" class="classname"/>and then use the getProperty tag
or even Custom Tags

How to call custom Login Module from JSP

Hi,
I am stuck with the following issue:
1) Exactly as presented in help.sap.com (http://help.sap.com/saphelp_nw04/helpdata/en/3f/1be040e136742ae10000000a155106/content.htm) I created custom login module and deployed it as a library on J2EE server. When I configured it to be used for my applications in the Security provider but I am getting "No user name provided" exception everytime when my applications use this custom login module.
2) I realized that I would need to call my custom module somewhere within my application (simple JSP) using LoginContext class and then use MyLoginContext.login() spec to initiate login process. But I am not able to pass CallbackHandler parameters from JSP application to my custom login module.
So I have the following questions:
1. Can I pass parameters using LoginContext and CallbackHandler from JSP to my custom login module (created as exact copy of HELP.SAP.COM example) or this module cannot be used this way.
2. How to pass CallbackHandler correctly to my custom login module from JSP. When I am trying to use CallbackHandler, I am getting "Abstract Class cannot be called" error.
I'd appreciate any little help on this matter.
Thanks and regards,
Mike

You have two alternatives to do this:
You can declare your JSP as a protected resource with the use of the deployment descriptors of the application (web.xml) and add the custom login module in the authentication stack of the application. This way, you will use container-based authentication, i.e. the Web Container will enforce the authentication and it will call the custom login module before it dispatches to the JSP. I recommend you this approach because it requires less coding and it makes the whole thing a matter of configuration. The configuration can be later on enhanced or changed runtime without the need to re-build and re-deploy the application. If you choose this approach you can go to the documentation of the server for help on how to modify the login module stack of the application.
You can also use programmatic authentication by using JAAS API. To do this you need to create a custom security policy configuration with login module stack containing the custom login module, and then use the standard JAAS mechanism - new LoginContext(<configuration>, <callback-handler>).login(). This approach requires that you write your own callback handler and handle any LoginException.
Let us know which approach you prefer and whether you have difficulties implementing it!

How to call OWB Process Flow from APEX?

Hello.
I was wondering if there is a way that I can have a OWB process flow kick off from a button in APEX? I know you can have APEX perform PL/SQL upon being clicked, so I am wondering if there is a way that I can do the same for a process flow? We are looking to have a manual kick off for a job and we are trying to use APEX for this. Any information would be great!
Thank you

How to call/show page(s) from different application

Hi All,
I'm working on couple of applications and some reports (about 30) are used in all applications. I need your advice on doing this efficiently.
Is it possible to
1) Create a separate application with all the reports.
2) Create a blank page with lists linking to all those reports on the same tab
Now, is it possible to call that page in a "reports" tab of each application without prompting for login and still have rest of the tabs visible while the user is using the reports?
Thanks in advance,
Asha

Asha,
you can create links to call pages from other applications without any problem, just take a look at the structure of APEX URL over here: http://www.oracle-and-apex.com/apex-url-format/
To avoid re-logins you could either disable security on your application (not recommended) or create a custom authentication scheme which takes logged in users from other applications as granted.
brgds,
Peter

How to call PL/SQL function from JSP ?

We have the JSP application developed using the JDeveloper 3.0. I am trying to call the PL/SQL DB function. I'm trying to use the method of ApplicationModule:
.getTransaction().executeCommand(sCommand)
The problem is that I can not get the function result back to JSP. The executeCommand() does not seem to accept any host variables.
What to do ? Did anyone manage to get the feedback from DB ?
Here is the code in the JSP page:
<%! String res=" ";%>
<jsp:useBean id="rsn"
class="oracle.jbo.html.databeans.TRSRowSetNavigator"
scope="request" >
<%
rsn.initialize(application,session, request,response,
out,"theIMO_trs_bc4J_Bc4JModule.AuctionsListView");
rsn.setReleaseApplicationResources(true);
// this is the ID to be copied
String copy_id = request.getParameter(TRS.LOOK_UP_PK_FIELD);
if( copy_id != null) {
// call the PL/SQL procedure to create copy of this auction
String sCommand = "DECLARE a NUMBER; BEGIN :res:=Copy_Auction("
copy_id"); END;";
rsn.getRowSet().getApplicationModule().getTransaction().executeCommand(sCommand);
rsn.getRowSet().getApplicationModule().getTransaction().commit();
I receive the following error:
Error Message: JBO-27121: SQL error during statement execution. Statement: DECLARE a NUMBER; BEGIN :res:=Copy_Auction(45); END;
JBO Error:JBO-27121: SQL error during statement execution. Statement: DECLARE a NUMBER; BEGIN :res:=Copy_Auction(45); END;: ORA-01008: not all variables bound
What criteria has the host variable meet to be used in the executeCommand(sCommand) method ?
Thanks,

I could be wrong there, but I have experienced similar problem on tru64 unix, with sticky bit not in place for the following files: $ORACLE_HOME/bin/oracle and $ORACLE_HOME/bin/oracleO. Once you restore those files via tar command (this is what happened to me), the sticky bit disappears, and you have to re-introduce it by issuing unix command: chmod 1777 on those files.
What it does for you - it allows you to execute the sql statements as an oracle user & group!
Otherwise, if this bit is lost, whenever you try to connect to sqlplus via user / password it hits you back with:
ORA-01034 ORACLE not available
ORA-27121 unable to determine size of shared memory segment
Compaq Tru64 UNIX Error: 13:Permission denied
This should not be a problem if you try and execute the same sql statements using listener (connecting to the server by using @ statement).
I could be late in response to you, but maybe not for other people.

It might compile perfectly well, but the message suggests that you didn't deploy it properly. The class loader can't find it.
That .class file should appear with its package directory structure under the WEB-INF/classes directory or in a JAR in your WEB-INF/lib directory in some WAR file. Does it?

If you do the redirect with javascript, the user cannot resubmit his login when he presses the refresh button. When he does press refresh, he only refreshes the redirect, not the form post that was before it. When he presses back the redirect will also kick him back in stead of going back to the login page. A simple javascript redirect page would look like this:
<html>
<body onload="document.location.href='myhtmlpage.htm';">
</body>
</html>But that is only if you care about resubmits of course.
