Hi everyone is there a method to remove a servlet or servletcontext from an embedded jetty server version 9 like remove servlet? I specify version because SO has an answer for jetty version 7 but i have the same doubts about the technique used as mentioned in the comments on that thread

I have found an application that is made with spring 3.2.18.RELEASE and is running on tomcat 9 and java 8.
My knowledge of java and spring is very little, but from what I understand spring 3 should work with Servlet 2.5 API.
But according to tomcat page, servlet 2.5 is for tomcat 6
Can an application made with spring 3 run in java 8 with tomcat 9 without problems?
What would be the ideal version of java and tomcat for spring 3?
How should the correct versions of java, tomcat and spring be selected?
I suppose that will be running ok. I am usign Java 8, Tomcat 8 and Spring 4 and works correctly. And Tomcat 9 also support Java 8.
Previously I did an web application in spring MVC on Apache Tomcat 5 and i wanted to migrate it to Apache Tomcat 7 now . May I know the steps for the migration.
Can anyone help me out ?
It should be straight forward. Please keep the following points in mind before you migrate.
Apache Tomcat 7 requires Java 6 or later.
Apache Tomcat 7 supports Java Servlet 3.0, Java Server Pages 2.2,
Expression Language 2.2 and WebSocket 1.1
In JSP pages that use wildcard import syntax the new classes added in Servlet API may conflict with ones in web applications. For example, if package "a" contains class Part, the following JSP page will cease to compile in Tomcat 7:
<%#page import="a.*"%>
<% Part page = new Part(); %>
That happens because implicit import of javax.servlet.http.* and explicit import of a.* will provide conflicting definitions of class Part that was added in Servlet 3.0. The solution is to use explicit import, import="a.Part".
All configuration options that use regular expression now require a
single regular expression (using java.util.regex) rather than a list
of comma-separated or semi-colon-separated expressions.
Please refer here for more information about migrating to Tomcat 7
If you have a .war file of your project, then its too easy to deploy application on Tomcat 7. You need to just open you apache tomcat 7 admin console and deploy .war file and it should work fine.
I am upgrading my old Java webapp using JSP spec 2.0 to tomcat 7 that uses JSP specs 2.2 and the EL specs have changed much in recent versions of Tomcat 7. I have a lot of JSPs that uses old EL that are not compatible with newer versions of EL in JSP 2.2.
My question (Futile alert!), can I somehow change Tomcat 7 to use JSP 2.0 spec. You'd say why don't I use older Tomcat; I can't because I need to use Servlet 3.0 specs.
No you can't. If you somehow did, you wouldn't be able to use Servlet 3.0 because your JSP(s) are compiled into Servlets. Tomcat releases are tied to JSP and Servlet versions.
Per the Apache Tomcat 7 documentation,
Apache Tomcat version 7.0 implements the Servlet 3.0 and JavaServer Pages 2.2 specifications from the Java Community Process, and includes many additional features that make it a useful platform for developing and deploying web applications and web services.
I have created dynamic web module with EAR reference to deploy it in the Websphere 6.1.
Then we are requested to have it in the Tomcat 5.5 server. Display Tag is not populating data from action class.
My java version is pointing to websphere6.1 version, struts2, displaytag 1.2 tomcat 5.5.
Let me know the issue? Any compatibility issue?
I faced compatibility issue for struts2 in websphere 6.1. Is it anything similar for tomcat?
Hi all i am developing a web app and deploy that in tomcat 7.0 and when i try to run the same thing in tomcat 5. i get the following exception while deploying itself.
Tomcat version 5.5 only supports J2EE 1.2, 1.3, and 1.4 Web modules
i think these cost the problem but not sure
import javax.servlet.annotation.MultipartConfig;
import javax.servlet.annotation.WebServlet;
#WebServlet(urlPatterns = "/ReadEmployeeAttendance")
#MultipartConfig
how to solve this?
You can't do this. You need container with support for Servlet 3.0 spec, and if you want Tomcat that is only Tomcat 7. If you want your app to run in Tomcat 5.5, you cannot use Servlet 3.0 features (e.g. annotations, also your web.xml must have version="2.4" or earlier).
Yes you are correct that Tomcat 5.5 doesn't support Java EE 5 and above, you will have to upgrade to latest tomcat if you want servlet 3.
Every web server or application server implements specification provided by JCP, hence not all version of your server can run every version of specification, though on a general note they are backward compatible, meaning on Tomcat 7 you can run J2EE 1.4 but on tomcat 5.5 you cannot run Java EE5.
