jsp - How to stop getting error report in Tomcat -


i created jsp page test how connect oracle, using code.

  string conn_string = "jdbc:oracle:thin:@localhost:1521:orcl";      try {         class.forname("oracle.jdbc.driver.oracledriver");     } catch (classnotfoundexception e) {         e.printstacktrace();     }     connection conn = drivermanager.getconnection(conn_string,             "ums", "d0801213177");

when happens such oracle initializing or tns refusing take more connection or password of database changed then, error report when load page. displays total connection string. if happens when user using page security lost.

so, question is there way stop tomcat form reporting errors?". if there better way please tell.

follow up: if using prepared statements, errors table/view doesn't exists these types of errors general need put each block in separate try catch blocks?

edit

as beginer, struggling hide stacktrace because showing connection string, username, password too.

now know should have never written code in jsp in first place. using servlet task have been better

jsp gives option specify error page each jsp. whenever page throws exception, jsp container automatically invokes error page.

<%@ page language="java"  errorpage="" %> <html> <head> <title>error handling try catch block in jsp</title> </head>  <body> <% try{      string conn_string = "jdbc:oracle:thin:@localhost:1521:orcl";      try {         class.forname("oracle.jdbc.driver.oracledriver");     } catch (classnotfoundexception e) {         e.printstacktrace();     }     connection conn = drivermanager.getconnection(conn_string,         "ums", "d0801213177"); } catch(exception e) {   e.printstacktrace();   out.print("error caught catch block : "+e.getmessage()); } %> </body> </html>

preferably business logic inside servlet , redirect using requestdispatcher jsp.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
