Tips and Tricks- 8

1. Tomcat Server not starting with in 45 seconds
Delete the server from eclipse and reconfigure it or add it again to Eclipse.


2. Accessing Apache tomcat 7 built in Host Manager GUI

Change the Tomcat\conf\tomcat-users.xml file as follows:
<role rolename="manager-gui"/> <user username="admin" password="password" roles="manager-gui"/>

Start tomcat and access: http://localhost:8080/manager/html with the provided username and password


3. HTTP Status 405 – HTTP method GET is not supported by this URL
The reasons are:
1) You do not have a valid doGet() method, when you type the servlet’s path in address bar directly, the web container like Tomcat will try to invoke the doGet() method.
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException{

}

2) You made a HTTP post request from a HTML form, but you do not have a doPost() method to handle it. The doGet() can not handle the “Post” request.
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException{

}

4. Tomcat Server is not starting and there are no output logs.
Check whether the JAVA_HOME is properly set.
