HI,

I could resolve the problem as under:

<?xml version="1.0" encoding = "UTF-8"?> <project default="main" basedir="."> <property name="dist" location="c:/apache-tomcat-7.0.11/webapps/kavitaexamples/WEB-INF"/> <property name="app" location="c:/apache-tomcat-7.0.11/webapps/kavitaexamples/"/> <property name="src" location="source" /> <property name="output" location="classes" /> <property name="staticpages" location="pages" /> <target name="main" depends="clean,compile,deploy"> <echo message="Deploying the Web app...."/> </target> <target name="clean"> <delete dir="${output}" /> <mkdir dir="${output}" /> </target> <target name="compile"> <javac srcdir="${src}" destdir="${output}" /> </target> <target name ="deploy"> <echo message = "Copying files"/> <copy todir="${dist}/classes"> <fileset dir="${output}"></fileset> </copy> <copy todir="${app}/pages"> <fileset dir="${staticpages}"> <include name="**/*.jsp"/> <include name="**/*.htm*"/> </fileset> </copy> <copy file="${src}/web.xml" todir="${dist}"/> <echo message = "Files copied"/> </target> </project>

Is there a better way of copying the webapp files into tomcat? Would appreciate any pointer.

Thanks,
Kavita

Hi,

I have the following code in my build.xml file

<?xml version = "1.0"?>
<project name="kavitaexamples" basedir ="." default = "init">
<target name="init">
<delete dir="classes"/>
<mkdir dir="classes"/>
</target>
<target name="compile" depends="init">
<javac src="." destdir=".">
</javac>
</target>
</project>

I have my hello.java file in the current directory.

The build is successful, however the hello.class file in not created in the current directory. Only classes folder gets deleted & recreated.
Please guide me as to where I am going wrong.

Thanx Lalitha, your code really helped !!!

Hello...
Thanks for the replies. I thought the same. This question was asked me in the interview and therefore i was wondering whether there were any different views.

Hi...
I believe using struts might help you to proceed. Struts is the framework based on the MVC pattern. It helps u to have one controller servlet and several models with ofcourse various presentation patterns.Therefore, you can have the CompanyModel,LoginModel with a common controller servlet for the interaction between the bean & the presentation layer.
Hope this helps.

Hello,
Please explain the reason for error
class constant
{
int x = 10; //compiles
int y;
y=10; //complie error identifier expected
}
Thanks.

I was playing around with the following code and found the result very surprising.
char e12 = -12; //illegal assigning an int to a char. required char ==> OK
char e12 = (char) -12; //COMPILED
System.out.println("e12=" + e12);
OUTPUT:
?
Out of inqusitiveness i changed the values of char to -1, -2, -12, -13. In all the cases the o/p produced was ?.
Please explain why the same o/p for different values of char.

Please reply.

Hi,
I want to run a specific(rename the files that he has accesed on my server)action at both the instances -- either the user logs out or he/she shuts down the browser directly without loggingout.Its no problem whenever the user logs out properly bcoz that time i can run my servlet.However what if the user does not logout and closes the browser directly.
Any suggestions as to when should i run the servlet --
One solution i can think of is i can run the servlet maybe after every 20 mins.But then if i use this method then how do i invoke it every 20 mins.I am using Tomcat v 3.2.
1.Also is it an optimal solution???
2.Will it not increase load on the server-----Renaming few files every 20 mins.???

Is there any better alternative???

Plz. reply ASAP.
Thanking in advance,
Kavita

Hello,
These days there is economic depression going on throughout the world.No industry seems to be doing well.Although comparatively software industry is better then the rest.(My observation atleast in India.)
In software also it seems Embedded systems might be the way of future.What will be the role of Java in such a scenario?? Can it do what C/C++ is doing currently?? Can it dominate the market the way C/C++ is??? Any Comments??
