Java does not allow a 'method' to be more than 64k byte codes (internal java compiled representation.)
So you have a method that is too large and you MUST break it into smaller methods. That would be the only possible solution.
In some cases if you are attempting to initialize static data, for example an array, list, etc, as a local variable you will get this error also because initialization is handled by the java compilers by creating a hidden method. Solution for that is to change how the initialization is done such as loading the data from a file.
Without entering in deep functionality of Servlets, what is it's use? To run some code, and at the end to redirect the user to another web page?
I'm asking because maybe there are some situations where you don't need to redirect the user to another page after the Java code from servlet is done. In this case, is there a way to stop the servlet from redirecting the user to another page? Even if you don't add a redirect or forward to the servlet, it will still redirect the user to it's map url.
I need a human understandable definition of how java script interprets. It seems to be a dance between html pages and forms, and .js Files. I have 40 years experience in coding in 'C' and 'CPP'. The syntax of java is indeed similar. This language provides apparently no type info of any kind. params, indeed the whole of js seems to be devoid of types.
As Richard has pointed out - you'll get better answers in the right forum.
There are further links in that article to other interesting "stuff" to help you in your research.
Note that I'm not actually advocating the how stuff works site per se, but you can pick up useful terminology that makes google searches more focussed.
I just started to learn Java Servlet, but I can't really make it work.
I'm trying to do something basic first, to see how it works, read data from a form, print the 2 values to in the console and then redirect the user to another page.
Using the following code (what I though it will do it), redirects me to another page that doesn't exist "/Testare?firstName=Example+First&lastName=Example+Last"
I'm using Apache Tomcat for server.
The form is on Home.html:
<form action="Testare" method="GET">
First name:<br> <input type="text" name="firstName"><br>
Last name:<br> <input type="text" name="lastName"><br>
<br> <input type="submit"value="Submit">
Testare servlet doGet trying to print and then redirect to "Test.html":
If the redirect page doesn't exist then it isn't going to work regardless of what you do.
If the initial page doesn't exist (it is not serviced) then it will not work regardless of whether the second page exists or not.
Redirection is handled by the browser not the server.
Here is an example which should have a working redirect.
