Upload video by using jsp/servlet

I'm using jsp/servlet to upload video file but I have a problem.
This error occurs for preparing SQL statement when I cast OraclePreparedStatement.
It is " Error : weblogic.jdbc.rmi.SerialPreparedStatement

Please help me asap.

You need to use the Oracle jdbc driver. Apparently, the Weblogic JDBC driver is being selected:
weblogic.jdbc.rmi.SerialPreparedStatement
The Oracle JDBC classes can be found in <ORACLE_HOME>/jdbc/lib/See <ORACLE_HOME>/jdbc/readme.txt for how to specify the correct class path in the application.
I would have thought that the oracle JDBC driver would have been selected (if in the classpath) or an exception would be raised if the Oracle JDBC driver was not found.... because the code should include:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
This should load the Oracle jdbc driver and classes, not the weblogic ones. IF the Oracle JDBC drivers are not found, an exception should be raised...

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.

Examination system using JSP/SErvlet and MySQL

Hi
I am new to JSP /servlet.
I am designing online examination system using JSP/Servlet and MySQL ,where multiple choice questions would be selected randomly from the database. After completion of the examination user gets the results ,also the results would be stored in the database for the future reference.
Can anyone guide me for this? If possible give me the code for similar type of application.
Thanks

Sounds like you want someone else to do your homework for you, did you not read this:
"This forum works so much better when you try to program the code yourself, then let us know where it doesn't work. Otherwise you learn very little, and we work a whole lot."
and this
"If you want free code, have you tried searching Google for it? You may want to consider looking for survey software. It will give you the question/answer capabilities then all you have to do is find a way to grade the survey (if you will)...
If you are using Tomcat as your server, which you probably are, there is a jdbc tutorial included in the documentation, that is the fastest way to set up your database.
As for your random selection, have a look at Math.random(), this is one way to generate random numbers, you will need an algorithm to convert this value (between 0.0 and 1.0) into a form that can be used to select information from your database.

Any good books on web application using JSP/servlet?

Does anyone know good books on how-to build enterprise web application using JSP/servlet? Aside from the book "Head First JSP/Servlet". Development using Netbeans is more preferrable.

What about the free web server? JBoss or Glassfish or something else? I prefer web/application server that is fully compatible with JEE6 (unlike Tomcat that can't handle EJB). thanksI'm a JBoss user myself, so naturally I would advise that to you if I were ignorant. I'm not however, so in stead I'll tell you to investigate yourself and see which one you prefer. Nobody is going to tell you which one to use as there is no such thing as a 'better' or 'best' server. Just different servers each with different issues.
And the community edition of JBoss has had many issues in the past (because Red Hat of course wants to advise you to go to the enterprise platform which ain't cheap), but JBoss 5.1 was a rock solid piece of software that I have had zero problems with (after reading the odd forum or two). JBoss 6 builds on top of JBoss 5.1 and provides the full JEE6 web profile; this means it does NOT provide a certified 'full' JEE6 stack yet. This means nothing however as all the services you may need in an enterprise application are already there.
BTW: for simple servlet programming, don't neglect Apache Tomcat. Its a lightweight server that just works.

Hi,
Looks like you are missing a file from the classpath. Make sure servlet.jar is available in your classpath. Ordinarily files in <tomcat_home>/lib directory should be added automatically. You need to check why it hasn't been added in your case. A good place to start would be the bat files in the bin directory viz startup.bat, catalina.bat etc.

hello,
there are multiple documents out there, describing the oracle reports server setup. try doc.oracle.com for documentation.
also it is part of the online-documentation.
you need to install 9iAS enterprise edition. the server is pre-configured and will listen to the url http://yourserver/dev60cgi/rwcgi60.exe
passing only this url you will get a help-screen, describing the syntax.
regards,
the oracle reports team

Determin how many user log on the site using JSP/Servlet?

Hi all,
Is there a way to determine how many user log on the site using JSP/Sevlet? I'm running Apache 2.x & Tomcat 4.x
I'm trying to get a list of user currently log in the site.
Please help!
Thanks,
-JN-

You could use the HttpSessionBindingListener interface. Every time a user logs into the session put a user object into the session. The user object will implement the HttpSessionBindingListener interface. When the user object is added to a sessiion it recieves an event and it increments a counter. When the session times out or you invalidate the session because the user has logged out the user object will recieve an event and it can then decrement the counter.
This will at least tell how many active user sessions there are.

Uploading External Documents (*.doc, *.pdf, *.html) using JSP, Servlets, JDBC

I would like to upload external documents to an Oracle 8.16 db without using agents or interMedia.
Documents can range from *.doc, *.pdf, *.html and so forth. Ive been all over OTN and all I keep finding are examples on uploading Audio, Video or Image data - which is fine.. but damn, can we get a couple "Real World" examples in there?
Im even looking at iWorkplace which is excellent.. but a little out of my league when it comes to uploading external documents. But that's exactly what Id like to do. The documentation on this issue is very scarce - Please help.
Any help in this matter would be greatly appreciated.
Many Thanks in Advance.

Is anyone having problems loading text files using this routine? I can load a file with this, but even though the table contains a CLOB, the file is uploaded as binary and one only sees a series of question marks when looking at the CLOB. So, basically, the file appears to be converted somehow from text to binary. Any thoughts? I'm using 8.1.6.0.0 on Sun Solaris 2.7. character set in the database is UTF8.
Thanks.

Can I delete a file in my web folder using JSP/servlet?

I want to delete some of the files in my website. How can I give file path. I have uploaded my website in US. Just by uploading a servlet /jsp I want to delete files in my directory.
Is it possible to delete files using Servlert/jsp. What path should I give for the file name in jsp/servelet?

It is possible. You can just specify the absolute file path in a File object and then invoke the delete() method. File file = new File("/path/file.ext");
file.delete();See the File API [1] for details. Further on I think that you also want to know how to get the absolute file path for the given relative path. If so, it's available by ServletContext#getRealPath() [2]. To get for example the absolute root path, just query the relative root path "/":
String rootPath = getServletContext().getRealPath("/");[1] http://java.sun.com/j2se/1.5.0/docs/api/java/io/File.html
[2] http://java.sun.com/javaee/5/docs/api/javax/servlet/ServletContext.html

Sharing data across different webapps using JSP/Servlet

I have two different web applications running on same WebLogic server say webapp1 and webapp2. Webapp1 has servlet which redirects the user to JSP in webapp2. While redirecting I have to pass one string value to called JSP. I have achieved this by using QueryString as follows:
response.sendRedirect(ConfigService.getProperty("com.twofactauth.caymanlogin.caymanurl", null)) + "?userName=" + strCaymanUserName);
but this expoes the value in browser address bar but i don't want to expose the value passed. I am searching the way to pass the value internally without exposing.
so please tell me other way in which i can pass the value to called JSP without usign QueryString.
I am using WebLogic 8.1 for deployments. Both applications are deployed on same WebLogic instance.

I am using WebLogic 8.1 for deployments. Both
applications are deployed on same WebLogic instance.I think a big part of the problem is that you want the functionality of a web app to be available to others, but you've locked it up behind a UI.
I think this is one of the benefits of a service-oriented architecture. You start thinking about the system functionality apart from the UI. Your JSPs become just another client of the services you expose. Anyone can call those services, as long as they can see that service on their network.
When I've done this I've started with a Spring service interface that is completely separate from the view layer. Once I have that, I can expose it to any other client either with web services (not preferred) or Spring HTTP remoting (preferred due to its simplicity).

You mean Servlet.
FrontEnd: Netbeans6.0Netbeans is not a front end to anything. It is an IDE.

I need Jsp code and table creation code i want to create in the Database.This site is not a place to get codes. This site is a place to get help with codes you have written. This site is also not an Oracle or general database or SQL question support forum.
