deprecated method
code
/* creating the object for DatInputStream */
//DataInputStream din=new DataInputStream (System.in);
/* calling the readLine() method
// din.readLine();
readLine() method of java.io.DataInp utStream is deprecated :my java compiler(jdk1.4 ) says.
please guide me what is the method that can replace readLine()
with regards,
shailesh -
first make sure you have this
JAVA_HOME=java installation directory path
CATALINA_HOME=t omcat installation directory path.
while compiling servlets you have to set the path
for example ,if your tomcat is installed in c:\program files\tomcat 5.5 then
set the path as
set path=c:\tomcat 5.5\common\lib\ servlet-api.jar;%classp ath%
then compile the servlet.

whether solves your problem or not,

constructors are not inherited.Leave a comment:
