Prompt error message in JSP
May I know how to prompt an error message in JSP?? can I use alert() as in javascript? what's the proper syntax to do it???
Just to simplify what is already said: All JSP code, without exception, is executed on the server side, and when the JSP page is shown to the user (client) there is no execution of any JSP CODE, you can only use the information supplied by the JSP code.

Interrmittant dispaly of error message on JSP Page
Hi ,
I am developing an application using JSP and servlets. I ma having a peculiar issue with it.
I have few links on a JSP page. When a user clicks on the link, its credentials are verified from database and if he is authorised, he will be taken to corresponding link page. Otherwise an error message is dispalyed on the same JSP page.
When user is not authorised, an exception is thrown from backend to UI passing an error code. This error code is extracted in UI and error description for this error code is read from a properties file.
From the servlet I use send.redirect() calls to redirect to the url with error code concatenated at the end of the url.
It is something like this
try {
if(validUser)
//do stuff
response.sendRedirect("abc/xyzServlet");
} catch(Exception ex) {
errid=ex.getErrid();
response.sendRedirect("abc/MainPageServlet?errid=" + errid);
}In the MainPageServlet, i read error properties file and display error desc for that error id.
The problem I am facing is that when an unauthorised user clicks on link repeatedly, he sees the error message intermittently.
But the error id could be seen on the page url appended.
Sometimes I also see IllegalStateException in the logs.
I am using WebSphere server to deploy the application.
Please help me on this, I have spent much time on this and haven't got a clue. Any pointers will be useful.
Thank You,
Priyanshu.

Edited by: galapagos on Feb 28, 2008 10:44 PMI've tried this and the message still comes up all the time. Have also tried resetting and this doesn't work either. The message appears whether or not it is connected to an accessory (eg speakers). Any further ideas?

Display error message on jsp if there is an exception during pdf generation
I am displaying pdf from my application and when the pdf document is found, it is displaying properly. Only problem is when the document is not found i want to display the jsp with an error message to the user. I am using IE and IE has a bug that it calls the servlet twice to display pdf. Please refer to this forum and IE bug info.

(newbie) How to return error messages to JSP page.
Hello,
I'm using a very simple Model 1 architecture (no framework such as Struts used.) The webapp just consists of a login.jsp which collects database connection parameters and then activates a servlet to return a PDF report to the browser.
I have a very common need: I would like the errors entered by the user on the login.jsp to be displayed at the top of a new return of the login.jsp (with the bottom of the JSP still providing the edit fields for reentry), errors such as:
1.) User did not enter the username, password, and database name
2.) Having a wrong username/password for the given database.
(2) is more complex than (1), because it would involve feedback from the servlet (which makes the DB connection).
I'm not sure how to code this, however, with just JSP, JSTL and JavaBeans. Does anyone know of an example with source code on the web where something similar to this is done?
Thanks,
GlenNo problem on posting here. Seeing as JSP forum is not accessible, this is the next best choice.
What sort of complexity are you after here?
You can go with the very simple:
Print out the error messages as you discover them.
if (request.getParameter("username") == null){
// print out the message
out.println("Please enter your username");
// or alternatively
List errors = new ArrayList();
errors.add("Please enter your username");
}The best way to get feedback is to write your login method to return whether login succeeded or not. That can be a boolean true/false value, or you could return a User object to indicate success, and null to indicate failure.
How much of the code is in servlet, how much in JSP? -
Customizing Error Message in Jsp app.?
Hi,
In my small application created by JDev10g wizard, I would like to customize errors received from database on dml operations before showing on jsp page. How/Where could I capture the error?
Please advise.
ThanksI have the same functionality with the automatic commit in the Datahandler onEvent (update/delete and create). I ran into the same "OnEvent" problem. I think the problem is the result of having the "<jbo:Row>" tag inside of a try/catch block. From my experiments, I was able to determine that the errors almost always related to some sort of row handling. They always happened after the code within the try/catch block failed. I found that it would work fine with just the commit inside the try catch block. As soon as I tried to catch an error in the "<jbo:Row>" tag everything went screwy. This is no good considering that I have custom errors that are thrown when you try to create/update an attribute (before commiting!).
So far, I have been able to work around this somewhat. I don't get any errors if I create a Row object programitically without the Oracle convenience tags. I tested this with the OnEvent(Delete) function because it is the easiest to replicate. Here is the code that I have that works for me:
<jbo:OnEvent name="delete">
<% // get the row from the parameter jboRowKey which is created automatically when you have addRowKey=true on your URL/Form event tag (default behaviour)
Row rowDelete = ds.getRowFromKey(params.getParameter("jboRowKey")); %>
<% try { %>
// call the remove() method of the entity you can overide this method if you want (I have). To do this, check the relevant box from the entity's java tab.
rowDelete.remove();
// commit this action right away
ds.getApplicationModule().getTransaction().commit();
} catch (JboException ex) { %>
// Catching those JboExceptions we created in the EntityImpl.java file
<h3 class="error">Error</h3>
<%=ex%>
<% // since it failed, rollback the transaction. Since I am commiting everything this will only rollback the delete command. I call it just in case the framework doesn't do this somewhere else! :)
ds.getApplicationModule().getTransaction().rollback();
} %>
</jbo:OnEvent>
I haven't been able to repeat this for the update or create OnEvents because they are much more complicated. Let me know if something like this works for you! Also let me know if you find a way to do this for create/update without being far too complicated.
If you are interested to find out what the <jbo:Row> tag does (to replicate it's behaviour perhaps?) you can find the code. It should be located in this file:
C:\<jdevDir>\BC4J\src\bc4jhtmlsrc.zip
If you open it you will find RowTag.java (or something) and that is what JDeveloper runs when you use the Row tag.
Hope this helps a bit!

Maverick: different usb cables to ipad2 prompt error message - won't charge
maverick prompts "ipad not charging - connect to a poer adapter or usb port on this mac to charge."
very same cables worked before update to maverick.Dunno if this will help you. I tried plugging in my ipad to the same cable that has been in the same usb port for ages and it would not charge. I tried tons of updates and nothing worked. While reading these messages I thought to try a different usb port (same computer) and it worked (at least it says it is). I have a early 2008 imac. Went from far right port (if facing the back) to middle (there are three.) I did turn off find my ipad, but I don't think that mattered and plan to turn it back on. Good luck. (All this to read a book I paid for on my computer!)

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...

Thanks,
Ritendra.I think too, that is a time machine problem.
I have 4 volume partions (3 hard disk) at this mac. I use only the time machine as backup system. Only one. Before I install Snow Leopard I use the latest MacOS X 10.5.8. Always the newest version of MacOS.
Perhaps I describe it: Under 10.5.8 I use the time machine backup volume at an external firewire drive, always the same. I switch off this firewire drive often. In this case (the drive isn`t connect) the icon of this partition"Pro10.4" was changed to the time machine volume icon, but the time machine does nothing at this partition.
After the installation of 10.6 I cannot access to this "Pro10.4" volume. I get the same error message if I want to open the external drive volume of my time machine backup. There is no problems with my other two partition. Of course my old V10.5.8 is at one of this partition. If I start my mac from a other partition (time machine is off), I have no problem with all partitions.
I change the name of "Pro10.4", but nothing is changing. The time machine protect the backup volume under V10.6. Unfortunately it choose an other partition, if it don`t find my external drive. How can I reset this state of my "Pro10.4"?
Thanks

I tried down loading mozilla firefox to use as a web browser. It was downloaded 100% then when prompted to "run" An error message comes up with a red cross and the message'This file is corrupted" and won't let me proceed. What do I do now?
It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.<br />
You can try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

How to get error message on the same jsp
Hi guys,
I have a login.jsp page and I want an error message to be printed "login failed" in the same jsp page when the user enters the wrong credentials.
Any ideas on how to do that is highly appreciated.
Thanx in advance.sriIf you use struts it would have been a lot easier and better than only JSP.
In struts :
Add this line in ur JSP page
<html:errors/>
In ur Action servlet ex: LoginAction.java add thsi code extract in the appropriate position ...
ActionErrors errors = new ActionErrors();
errors.add(ActionErrors.GLOBAL_ERROR, new ActionError("error.user.wrong"));
if (!errors.isEmpty())
saveErrors(request, errors);
But in JSP do something like this:-
If authentication fails then post to the same JSP and put this code in the reqd position...
<%
String postFlag=request.getParameter("postFlag");
if(postFlag.equals("FAILED"))
%>
LOGIN FAILED
<%
%>
So for JSp simply set the request parameter (postFlag) to SUCCESSFUL/FAILED from your servlet. -
