is it required to restart Tomcat , whenever servlet class file is changed?

[yamini nadella]

Hi,
It is making me to restart tomcat whenver I changed the servlet. some times it is becoming compulsory to execute the URL in new internet explorer window.
Is there any way to reuse the existing explorer and tomcat without restarting?

Regards,
Yamini.

It depends on. If the Servlet instance is being used, you may have to restart it.

Instead of restarting the Tomcat Server, you can only restart the context associated with that servlet class.

Check the version of the Tomcat you are using. The latest versions of tomcat server starting from around v4.1.24 doesn't require restarting the server when the servlet is changed.

AFAIK,there are couple of ways

1. In your server.xml, add a DefaultContext subelement nested inside an Engine or Host and supply true for the reloadable attribute.

<DefaultContext reloadable="true"/>

You can also have this for a particular application instead of making it as default for all by using Context subelement nested inside a Host element as

<Context path="/web-app-name" reloadable="true"/>

If you don't prefer meddling with server.xml, same can be done using the Tomcat administration using the URL http://localhost:8080/admin/index.jsp

2.You can call the manager application to reload the application
http://localhost:8080/manager/reload?path=/web-app-name

You shouldn't have to restart tomcat unless the directory structure has changed.
