How to redirect to error.jsp, if servlet encounters error ??

how do i redirect to error.jsp file , if there is some error in my servlet file.
can i user response.sendRedirect() in catch clause or i should use RequestDispatcher in catch clause ??

You can use either way to redirect to error.jsp. If you want to pass your Request, response from servelet to JSP, then better to go for RequestDispatcher.

Applet in jsp from servlet, but error: ClassNotFoundExcep

The problem that I'm having is already mentioned a couple of times in this forum, but unfortunately I haven't found a solution, in thread http://forum.java.sun.com/thread.jspa?forumID=33&threadID=239405 is proposed solution but it's not working for me.
I'm developing a project in IBM's Websphere Developer Studio 5.1.1. and JRE that I'm using for this project is 1.4.2. I have created servlet "CompanyDocument.java" and applet "SimpleApplet.java". Applet was created as single project and then imported into this one, that means that it's contained in current project as "SimpleAppletPackage.jar". I have placed jar in folder "Applets", Websphere automatically creates folder "simpleAppletPackage" and in it's root complied "SimpleApplet.class".
When I put following code in the jsp page applet works correctly when application is runed.
<APPLET code="simpleAppletPackage/SimpleApplet.class" codebase="Applets" archive="SimpleAppletPackage.jar" width="250" height="250"></APPLET>
But I wanted to create jsp from servlet. So I used this code within servlet:
out.print("<APPLET code=\"simpleAppletPackage/SimpleApplet.class\" codebase=\"Applets\"");
out.print("archive=\"SimpleAppletPackage.jar\" width=\"250\" height=\"250\"></APPLET>");
But I get an error (when running, no error when compiling). The error is copied from Java console:
load: class simpleAppletPackage/SimpleApplet.class not found.
java.lang.ClassNotFoundException: simpleAppletPackage.SimpleApplet.class

In the same time I'm creating some more code from servlet and it works with no errors and is shown in browser properly (it consists of connection to Oracle, formatting table, and presenting data within that table).
Any idea? I'm totally stuck.

In your browser, look at the HTML code that gets sent to the browser and see if there is something wrong with it.
Specifically, I would look at the code near the <APPLET ..></APPLET> tags, both before and after and look for stray quotes, brackets, or what not.
Finally, I would look inside the <APPLET ...> tag. It appears to me that the output will probably be:
<APPLET code="simpleAppletPackage/SimpleApplet.class" codebase="Applets"archive="SimpleAppletPackage.jar" width="250" height="250"></APPLET>See, you may be missing a space between the "Applets" and the archive=. Try making the second out.print look like this:
out.print(" archive=\"SimpleAppletPackage.jar\" width=\"250\" height=\"250\"></APPLET>"); See the extra space at the start of the output?

How to go to new jsp from servlet.

In the results page, if a button is clicked, i go to servlet, then come back to display data from database in another page. It works fine but the problem is that I wnat to open up a new browser and display the target page there and not the results page.
results.jsp --> click button --> go to servlet --> display data on resultDetails.jsp (same browser window).
I want resultDetails.jsp in a new browser window.
my code in results.jsp is:
<input type = \"button\" onclick = \"location.href = 'Controller.wss?page=RESULT_DETAILS_PAGE&cmd_id="+cmdId+"'\" value = \"see details..\">
how can i change this. I am using java in jsp and out.println for any html content.
Thank you in advance. Any help (with/without) examples would be appreciated.
Bhavna.

1. Create a jsp (popup.jsp) file with the content you want for the pop up window (eventually read some parameters from the request, if you need)
2. when creating the resultDetails.jsp generate a JavaScript that opens the pop-up jsp file using someting like:
<script>
window.open("popup.jsp?param1=<%=param1%>&param2=<%=param1%>");
</script>

Error message from servlet to jsp

Hi again,
I have servlet and check error on this servlet then i would like
to send error message to jsp page.Every error message will send to
same JSP page.So JSP must receive message from Servlet.Can i do this?
Please give me details and some sourcecode.I will appreciate for your helps.

you could do something like this..
request.setAttribute("error", stringErrormessage);
Then in the jsp just do
<%= request.getAttribute("error") %>
That will print an errormessage.
Basically, by setting anything on the request and then redirecting to that page you cn display it...

How to redirect to an error page when database is down

We have build an struts/jsp-application with JDeveloper 10g and ADF. If the connection to the database fails, we get a plain page with header "500 Internal Server Error" and the exception and a stack trace. Of course we want to catch this exception and redirect the user to an error page with all of the standard design elements of our site and with a textual description of the error of our one choice.
Our attempts to solve this includes adding error-page tags with error-code and exception-type:
<error-page>
<exception-type>javax.servlet.jsp.JspTagException</exception-type>
<location>error.jsp</location>
</error-page>
<error-page>
<exception-type>java.lang.Exception</exception-type>
<location>error.jsp</location>
</error-page>
<error-page>
<exception-type>oracle.jbo.JboException</exception-type>
<location>error.jsp</location>
</error-page>
<error-page>
<exception-type>oracle.jbo.DMLException</exception-type>
<location>error.jsp</location>
</error-page>
<error-page>
<exception-type>java.sql.SQLException</exception-type>
<location>error.jsp</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>error.jsp</location>
</error-page>
Are there other ways to do this, or are there things we have forgotten to do, that has to be done for this solution to work.
We have also tried try and catch in a variety of the lifecycle methods in the DataAction subclass for the page, but none of these are ever called. It seems the error happens before the first lifecyle method starts. We can't figure out where to catch this exception.
In other cases the web.xml mechanism seems to work.

How to post an audio file in JSP or servlet

Hi,
I've loaded some rm files into the database. How do I retrieve and post it to the web using JSP or servlet page? How do I convert the ORDAUDIO to BLOB field? I went to the following example/demo:
http://www.oracle.com/technology/sample_code/products/intermedia/index.html
but didn't gain much help. Please provide me some sample codes using embeded tag. Thanks!
Regards,
Johnny

I''l try again.....
The response to your http page does not include media of any kind. The media is not part of your web response. It takes another request to get the media.
Your embed tag, image tag, object tag, anchor tag only reference the media data. Typically , in the case of an image, by a relative URL.
Your OrdAudio object can only provide the mimetype and other metadata when you are building your web page. You must have another endpoint to handle the delivery of binary media.
A simple servlet is typically used, Consider the following servlet. It delivers a HTML form, or Image media, depending on what the request parameter "what" is set to. If "what" is set to "form", it delivers an HTTP form that references this same servlet, except that in the image tag "what" is set to image, where the image object is fetched, and the binary media delivered (with the right mimetype). Just change the Image stuff to audio, the html image tag to an anchor or embed tag, and something like this should work for audio as well.
This is a bit better... , the <img src= is messed up, as are the <h1> tags...

How to redirect in java code not the jsp or any other

hello
can any one help me how to redirect in java pages the code must be in java function not in jsp or any thing else
thanks in advance

Function? Don't you rather mean method?
Anyway, in JSF you can send a redirect using ExternalContext#redirect(). If your JSF environment is on top of JSP/Servlet, then under the hood it basically invokes HttpServletResponse#sendRedirect() and FacesContext#responseComplete().

Jsp give me this error javax.servlet.ServletException: oracle.jdbc.driver.O

but jsp page not run
please give me idea how I how my oracle data in jsp page
thank
aamir

sir i post my problem but they reply me it java problem not oracle problem
*** oracle reply**********
You metioned that you use
jdbc:oracle:thin:@<ip or hostname of machine where your db is installed>: 1521:aamir , description to connect the remote database. So, I think it's not related to your tnsname.ora problem. It's only java oracle thin connection string. Please check this string, make sure the ip and database service name is right.
one more thing, use sqlplus check your tnsname.ora, if ok, then try to check jdbc and make sure the jdbc driver match to oracle server.
sir please give me idea how i show my oracle data in clinet browser
thank's

How to cluster the war file conatining the jsp and servlet by using wl6.0sp1?

There three wlsever6.0 sp1.
          One is admin server and doesn't join the cluster.
          Two servers are cluster server.
          I use the admin console to deploy the war file and the war file conatains
          the jsp and servlet.
          How to config the one of the clustered servers as the primary one, so that
          the client can request the jsp?
          If the one of the clustered servers is closed, can the client be redirected
          to another clustered server?
          Does the proxy server need to be exist?

How to track the same session using both jsp and servlets

Hello, guys:
"how to use jsp and servlet to track the same session",
it seems to me my logoff.jsp never realize the session I established in my servlets.
Here is how I set my session in my servlets:
" HttpSession session = req.getSession(true);
session.setAttribute("userid",suserid);"
Here is how I invalidate my session in my logoff.jsp
" <%@ page language= "java" %>
<%@ page import="javax.servlet.http.HttpSession" %>
<%@ page session="false"%>
Our Session id is : <%= session.getId() %>
<% session.removeAttribute("userid");
session.invalidate();
%>
Our Session id is : <%= session.getId() %>"
but when I try to logoff using the logoff.jsp
I always get following error message.
"/home/jiao/jsp_webserver/tomcat/work/Standalone/localhost/syllabus/htmls/logoff_jsp.java:50: cannot resolve symbol
symbol : variable session
location: class org.apache.jsp.logoff_jsp
out.print( session.getId() );"

So,
<%@ page session="false"%>
That means the jsp never instantiates the build in session object.
<%@ page session="true"%>
means jsp will instantiates a session object if there are no existing ones
how about I just delete the line,
does that mean the jsp will find the existing session object for me?
So I can do something like
Our Session id is : <%= session.getId() %>
<% session.removeAttribute("userid");
session.invalidate();
%>
directly.
