Answer 1

In the package explorer of your project, go to Java Resources> Libraries. Rightclick servlet-api.jar , select "Properties" and specify the source location there ( apache-tomcat-xxx-src.zip file).

Another way is to simply open any servlet API class using Ctrl + Shift + T or Ctrl + Click on any import / declaration in the existing code, and then click the "Attach file ..." button and specify it there.

Answer 2

You can download the source banks for the api servlet from Maven and either create your own javadoc jar or just use the sources.

Answer 3

First , download the "Full Documentation" from the tomcat website. As an example for tomcat 8.5.23: https://tomcat.apache.org/download-80.cgi

You will get a tar.gz file that you have to unzip since eclipse can only read folders or zip / jar.

Second , set the Javadoc location for your Tomcat library and "servlet-api.jar" in your Java build path. Point to the folder "(...) \ tomcat-8.5-doc \ servletapi":

And now the eclipse will show you the correct Javadoc:

I was constantly trying to pin sources for javax. libs properly without result, until it found that in some cases, for some reason, Eclipse messed up the connection between .jar and its classes. For example. when I clicked on Attach Source ... for HttpServlet.class this option to provide sources for my gwt-user.jar lib confused me a bit.

Therefore, you can try playing with the priority of your libraries in Project> Properties> Java Build Path> Order and Export to place your kit on top of the rest (for example, put the Apache Tomcat v7.0 library higher than the GWT SDK ). Also, on the Libraries tab, specify the correct source archive for servlet-api.jar , for example apache-tomcat-7.0.22-src.zip . Magically the problem is solved in the end.

In the package explorer of your project, go to Java Resources> Libraries. Rightclick servlet-api.jar, select "Properties" and specify the source location there (apache-tomcat-xxx-src.zip file).

or

In the package explorer of your project, go to Java Resources> Libraries. Rightclick servlet-api.jar, select "Properties" and indicate the source location there ( http://docs.oracle.com/javaee/7/api/ ). This will give a direct link to the api on the Internet.
