Eclipse juno won't hit breakpoints in GWT server side code running in tomcat
Turns out that instead of debugging it as a Remote Java Application, debugging it as a Web Application works. Still need to ensure that its in fact getting deployed to the correct tomcat installation directory. I've unchecked "Run built-in server" in the Debug Configuration for the Web Application type project. I've also ensured that eclipse has taken control of the tomcat installation identified in preferences. Manually setting the directory was not allowed as I had identified it separately in eclipse as THE tomcat installation dir.

How to tell tomcat to use an external lib while running from within eclipse
In Java web applications, the third party libraries must go in WEB-INF/lib directory. If there is no such directory, just create it and Tomcat (or another Java Application Server) will handle it automatically to use the jars inside it as part of the build path of the application. In short, create a folder lib inside WEB-INF and drop your external jars there.

Why am I getting ClassNotFoundException when running/debugging with TomCat through eclipse
Make sure under Java Build Path, on Projects tab you have other dependencies projects and on Libraries tab, all the jars your project uses. Since you are using Maven, check if your Maven bundle (Maven Dependencies) includes all the jars needed for your project. You can right click on your project, then Maven, then Update Project.

HTTP 404 Error when running a Hello World servlet with Tomcat 7 in Eclipse 3.7
If the server says ClassNotFoundException, it means the Class is Not Found Exception :-) Did you check your deploy and work directories inside tomcat? verify you really have the class inside your war (or uncompressed in the work dir) If not: put them manually to check your code works; then check why your eclipse or netb doesn't copy them to the server deployement dir

Stop a running application tomcat server
You could implement your job so that it periodically checks if it's allowed to continue. This is best practice for long-running jobs anyway. If that's in place, you can easily provide a UI for the feature - be it on application restart or individual per job.

How to deploy web project on remote tomcat server outside Eclipse with .jar files in it
You need to create jars for your project B & C an place them under the WEB-INFlib of your project A in tomcat webapps directory. Or if you don't create jars for your project B & C then copy the classes with proper package structures in WEB-INF/classes. You can always check what is going wrong in Tomcat/logs directory. A piece of advice: Familarize yourself with use of build tools such as maven and ant. I would recommend you to learn about maven, its dependency management, and build plugins. You can really make your life easier with such tools.

How to set up JAVA_OPTS for AspectJ to work in Tomcat running as a service on a Windows Server?
After a lot of trial and error I found out how to integrate AspectJ in Tomcat running as a Service on a Windows server. I do not know why, but the bolded stuff was the cause to my problems. Of course, as I mentioned in my question above you need the following prerequisites: Add aspectjrt.jar to the web application WEB-INFlib folder. Add vendorAspectJCode.jar to the web application WEB-INFlib folder. Add aspectjweaver.jar to tomcat's lib folder omcat7.0.27lib Setting -javaagent:PathToMyAspectjweaveraspectjweaver.jar in the service.bat did not work.

How to change port of tomcat from eclipse's tomcat plugin

My eclipse tomcat server is stopping and gives these exceptions "java.net.SocketException" and "java.net.BindException"
Look at the last stack in the logs and you find the root cause of your problem: Address already in use: JVM_Bind It means there is already a process running and listening on the port you try to use. Most of the time, this error is caused by a previous run of your own program that didn't terminate (properly), or is still running. Take a look in your IDE to see if you don't have some running instance alive (and kill it). You can also take look at running process under Windows task manager (or any other equivalent utility on other platforms) and try to identify the process using the port. You may also have a tomcat running as a window service: in this case, just change the port use by your program to avoid conflicts.

importing an eclipse project from file system, then running on server
A war file is a Web application ARchive (basically a zip). It is meant to contain a web application's compiled class files and resources (properties files, jsps, css, html, js, etc.). It a package that can be used by an application server (or servlet container) like Tomcat. Except through a Decompiler, you will not have access to the source code from the compiled .class files. I doubt you can run this on Eclipse's Tomcat instances. Instead go to your Tomcat installation. Mine is at C:apache-tomcat-7.0.22. Rename the war to something simple like security.war and place it inside the webapps folder, ie. C:apache-tomcat-7.0.22webappssecurity.war. Go to C:apache-tomcat-7.0.22in and execute the startup.bat Windows batch file. This script sets up the classpath and launches a Java application c

What happens when I run an application on tomcat in Eclipse
Environment assumptions I will assume: target/classes is the target folder for compiled classes src/main/webapp is the web application content folder Project > Build Automatically option is checked Deployment directory Eclipse is using exploded WAR deployment - i.e. the deployed application is deployed as a folder, not a single file archive. Application files are placed and loaded from ${workspace}/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/. Publishing Publishing is a central process which is responsible for assembling and deploying the web application. When talking about local Tomcat, this means copying "web content, compiled classes, libraries, ..." into deployment directory (the one in .metadata). Eclipse is able to do partial publishing - i.e. when a s

Tomcat 7.0.42 not starting in eclipse
I found my mistake from here. I had created Servlet using "Create Servlet" wizard which adds a @WebServlet(/servletName) annotation and no entry in web.xml I then created a entry in web.xml manually which duplicated the entry at the runtime. So you have to do either of the two with Servlet 3.0. Use Annotation like: @WebServlet("/testController") public class testController extends HttpServlet { } OR create a web.xml entry for your servlet. Read more: Servlet 3.0 Annotations

Issue when both apache2 server and apache tomcat server installed in my linux machine
Change the default port for Tomcat to something else, for example 8181 Current versions of web browsers recognize port 8080 like 80, so that's why it's forward you to 80 or cut the port option from URL. To change Tomcat port open server config file server.xml search for "8080", which is the current port in use, and replace it with something else (make sure the new port not in use), save and restart Tomcat.
