How to show the errors in browser from servlet?
con=dataSource.getConnection();
System.out.println("before..............");
System.out.println("1.the mag value is:"+req.getParameter("mag"));
System.out.println("2.the bu value is:"+req.getParameter("bu"));
System.out.println("3.the description value is:"+req.getParameter("description"));
cStmt=con.prepareCall("{ call PKG_MAG.SP_Insert(?,?,?,?)}");
cStmt.setString(1, req.getParameter("mag"));
cStmt.setString(2, req.getParameter("bu"));
cStmt.setString(3, req.getParameter("description"));
cStmt.setString(4, "nagireddy");
result=cStmt.execute();
System.out.println("after...............");
if(result){
con.setAutoCommit(true);
System.out.println("the procedure executed successfully");
req.setAttribute("getResult","Record failure........");
else
con.rollback();
System.out.println("the procedure failed ");
req.setAttribute("getResult","Record added successfully");
rs.close();
cStmt.close();
con.close();
RequestDispatcher rDispatcher=req.getRequestDispatcher("MagView.jsp");
rDispatcher.forward(req,resp);
} catch (SQLException e) {
resp.setContentType("text/html");
PrintWriter out=resp.getWriter();
out.println("<html><head><title>ERROR Page</title></head><body>");
e.printStackTrace();
out.println("</body></html>");
out.close();
}
e.printStackTrace() will send the stacktrace to the System.out, which will most likely end up in a logfile. One way to get the error to show up in the browser would be to rethrow the exception as a ServletException:
try{
} catch(Exception e) {
ServletException se = new ServletException(e.getMessage());
se.setStackTrace(e.getStackTrace());
throw se;
}Bit of a hack solution. You could also try this:
try{
} catch(Exception e) {
throw new ServletException(e);
}This will set your original exception as the cause of the ServletException. Tomcat (assuming you are using Tomcat) always prints a root cause, so I think it will display the exception correctly.

How to determine the error code, returned from LDAP server
I use the next code for connect to LDAP server:
try{
ctx = new InitialLdapContext(env, null);
//if connection successfull ...
} catch (NamingException){
//if error occured ...
}Is it possible to determine the numeric error code, returned from server?I was just working on using openldap, binding to it and checking for expired passwords and locked accounts and it looks like that an AuthenticationException is thrown in these circumstances and the ctx is null so it is not possible process connection response controls. But you can look at operation attributes if you have password policy enabled and you are looking for these type of errors

How to show execution error message from a Process
hi
i have a requirement like to display the error messsage returned by the proceure.
I have a process with point After Submit and validations, where i am calling a procedure which returns the execution status with SUCCESS or FAILURE;
and if it FAILURE, it will return the error_message also, how can i show this message to the user just like how we are showing the process success message/validation message.
And i need to stop the process execution there itself once its got failed;
how can i achieve these two? anyone can give some inputs....
thanks in advance
renjishpaul and denes, thanks for the quick reply...
i tried the both option the message is coming properly. but the thing is i want to stop the execution there itself where i got the error from the procedure and the page should be remained in the same page.
currently i have a page 10(customer search screen), from there i called page 102 (customer edit screen) and in the page 102 i attached the process which includes the procedure to update the customer details;
Normally if update is success, the procedure will return SUCCESS and its navigating to the page 10(customer search screen.). so here if FAILURE is returning by procedure, i need to be in the same page i.e 102(customer edit) by showing the error message..just like a validation message...
currently whatever the procedure returns either SUCCESS or FAILURE, it goes to previous screen, but i need the method just like how the validation works if it fails.
hope you got....
regards

This makes no sense. You don't configure a listener nor a tnsnames.ora "in a database". I hope this is just a language issue and not reflective of a fundamental misunderstanding of how tns works.

How to show the file contents in a streaming manner on the browser
Hi,
I have a log file which gets appended to by another program.
I need to show the contents of this log file in the browser window but in a streaming manner. Reading the file in one shot and refreshing the page every few seconds is not a solution as it makes the browser hang when the file size is huge. A unix tail functionality is also acceptable but it should be streaming. Would a servlet or applet do the trick?
Please advise!is your log file present on web/application server? if yes, you can do the following:
1. create a web page containing text area. (for displaying log file)
2. use XmlHttpRequstObject (Ajax) for querying the next available data from Servlet.
On the Serverside:
You can store the the FileScanner object in session scope. and use it to read the next available data and send it as response.
On the client Side(webpage/javascript)
read the contents of the response and append it to textarea.
In Simple words, I'd say AJAX is the way to go. -
How can I get iCal not to show the same birthday dates from my iCloud
How can I get iCal not to show the same birthday dates from my iCloud?
You don't need them stored locally for a backup. You can manually export your contacts as archive for backup. Also, if you are backing up with Time Machine, you already have a backup. If your hard drive crashed, you would have to rely on your backup or iCloud anyway.
So, if you're comfortable with that, sign out of iCloud. Choose to delete contacts from the computer. When you sign back into iCloud, you should only have iCloud contacts listed in AB. When you open iCal, you should only have one listing for birthdays.
The other alternative is to disable the Birthday c.alendar and create one manually. -

How to End the Error message: "enter the password for the exchange account"
i completed configure Exchange Account on my iPhone, but still show the error message: "enter the password for the exchange account"
make sure you don't have 2 step verification in gmail.
otherwise you need to follow
Signing in using application-specific passwords
The codes that you’ll get with 2-step verification don’t work with all applications. There are a few applications that use information from your Google Account (like the Gmail application on your phone, or Outlook) that require another type of code. These are called application-specific passwords.
Some devices and applications that use these special passwords include:
POP and IMAP email clients such as Outlook, Mail and Thunderbird
Gmail and Google Calendar on smartphones
ActiveSync for Windows Mobile and iPhone
YouTube Mobile on Apple devices
Cloud Print
Installed chat clients such as Google Talk and Adium
3D Warehouse, Sketchup, and installed applications
AdWords Editor
Sync for Google Chrome
Gmail Notifier
How to generate an application-specific password
Unlike a verification code that you receive from your phone or through Google Authenticator, application-specific passwords are generated. You don’t have to memorize them, ever - you simply generate a new one each time you need to sign into a particular application. Follow the steps below to generate your application-specific password:
Visit the Authorizing applications & sites page (pictured below) under your Google Account settings.
Under the Application-specific passwords section, enter a descriptive name for the application (label 1) you want to authorize, such as "AdWords Editor – Desktop," then click “Generate application-specific password" (label 2).
You'll then see the application-specific password you just created (3). You'll also see the name you wrote in for the device (4) and a link to Revoke (5) -- or cancel -- the code.
Once you click Done, you’ll never see that application-specific code again. But don't panic: You can generate a new one whenever you’re prompted for an application-specific password by a non-browser device or application -- even a device or application you’ve authorized before.
Using application-specific passwords
When prompted for a password when you sign in to a non-browser application or device that accesses your Google Account:
Enter your username.
Enter your application-specific password in the password field.
If your application has an option to remember your application-specific password or stay signed in, you can select that option so you won’t have to generate and enter a new application-specific password each time you access your account from this application or device. -
How to show custom error message in WebADI Excel template?
Hi,
I've created a custom Web ADI integrator and associated it with a 'Procedure' based custom interface.
WebADI Interface API Returns is set to "Error Message".
I'm using raise_application_error(-20001, "Actual Error Message") for invalid rows,but custom error message from PL/SQL is not populated on the excel template.
Instead it is showing "SQL exception occurred during PL/SQL upload".
Am I missing anything? How to show custom error message from Pl/SQL procedure to WebADI Excel template?
TIA
NarasimhaThe custom API errors are visible in the BNE log but not on the Excel.

Firefox crashes as soon as Flash video tries to load and Safari shows the error "Plug-in Failure"
I am unable to use Youtube or view Flash video on any sites.
Firefox crashes/quits as soon as a video tries to load and Safari shows the error "Plug-in Failure".
I have uninstalled Flash, downloaded a fresh version and installed, but no joy.
I am using OS X 10.6.6.
This is what I have tried so far;
1. Repaired Permissions.
2. Restarted with external drive and run Disk repair.
3. Restarted with external drive and run DiskWarrior.
4. Completely uninstalled Flash plugin. Robooted. Reinstalled Flash plugin. Rebooted.
5. I even installed an earlier version of the plugin to see if there was some incompatibility with the latest version.
6. Created a new user login and tried from there. Same problem.
Any ideas?You have what is necessary for Flash Player to be working. Firefox had some issues last year but it was after loading a video or the website. I had not heard of it lately and even last year don't recall it happening on the Macs.
What is happening with yours sounds like a direct conflict with some addon/extension.
Here is the link from Firefox describing what happened last year. You might want to see if there is anything more current.
https://support.mozilla.com/en-US/kb/The%20Adobe%20Flash%20plugin%20has%20crashed?s=Firefo x+crashing+browser&as=s
I'll get the Mac troubleshooting guide in a minute and post it also.
Any adblock or popup blocker software would cause this also.
