I currently have a working servlet created in Eclipse. When running it from the Tomcat plugin, everything works, and my app shows up at localhost:8080/project_name/. However, when I package the project into a .war file and place it in the /webapps directory of Tomcat and start the server, the servlet cannot be accessed. In Terminal, I can see Tomcat loading my project, and a temporary folder of the unarchived project is also created in /webapps. However, I simply cannot access my servlet.
Note:
I'm using Tomcat 7 and I don't have a web.xml file in my project.
How are you creating the war file? Check if your war files contain jar files under WEB-INF/lib folder and if the class files are not missing. You can easily verify it under tomcat/webapps/[project name] folder.

I have a web project that I'm developing in NetBeans 12.1 and I'm using Tomcat 9.0.38 as the webserver.
When I click the Build button or the Run Button, Netbeans compiles and builds the WAR package but instead of deploying it in the Tomcat's webapps folder in {CATALINA_HOME}/webapps/ it deploys the WAR file and extracts it in the NetBeans project folder MyProject/target/
After all this, Netbeans creates a config file in tomcat's config folder {CATALINA_HOME}/conf/Catalina/localhost/ called MyProject.xml that contains the path to the extracted war package in the project folder and the webapp works fine, but I don't want this deployment way.
Why is this happening?
I want to deploy directly from NetBeans to the Tomcat webapps folder. Do I have the wrong configuration?
I have a java project that use tomcat. when I run project in idea with tomcat(version 6)my project run in idea and in tomcat not create web inf file for my project and war file. why?
thanks
It should be a web project not java project and Tomcat is not responsible for creating web-inf folder. It is created when you first defined the project. Also are you able to see your war after building ? Does it launch the browser when you say running in Tomcat?
I developed dynamic web page in eclipse.I also configured apache tomcat in eclipse juno.In eclipse it run on server fine.I don't know how to deploy the dynamic web page in other system tomcat server.My folder structure.
Tomcat 7.0
-webapps
-Myproject-Folder
-WEB-INF
-classes
-lib
-web.xml
create a folder in your tomcat webapps folder
Then create another folder WEB-INF and index.html
Then in WEB-INF folder create three other folders classes,src,lib and web.xml
In classes folder keep all the .class files.
If you want to keep the source files then these should be placed in the src folder.
In the lib folder keep all the necessary jar files like activation.jar,mail.jar(if you are using java mail Api).
Now map correctly in web.xml
Now if your web.xml is correctly mapped then open a browser and type
http://localhost:8080/your_folder_name
8080 is the default port number.
just copy the "Myproject-Folder" to the "webapps" folder of any tomcat
Depending on how you want to deploy it, you can just copy the folder under "webapps" of your current Tomcat or package it into .war and put that under webapps folder of the target Tomcat.
I am trying to run the sample application from RoseIndia:
http://www.roseindia.net/jsf/SimpleHelloByEnteringName.shtml
I downloaded the source code, and put the folder in the webapps folder, as outlined. Do I have to create a .war or .jar from the app and put that somewhere in the webapps folder as well to run the application?
Can anyone guide me how to get Servlets working in Apache Tomcat server? I can run the Servlets from Netbeans without problems, but I don't know where to put the class files in Tomcat.
In tomcat:
class files must be in TOMCAT_DIR/webapps/<yourAppName>/WEB-INF/classes
jar files must be in TOMCAT_DIR/webapps/<yourAppName>/WEB-INF/lib
(and if course you'll need web.xml in WEB-INF)
They go in Tomcat/webapps folder. There are several ways to deploy a JSP/Servlet webapplication on Tomcat. They are all described in Tomcat Web Application Deployment HOW-TO.
If you already have developed the webapplication in Netbeans, then Netbeans should already have build a WAR file of it in the /dist folder. You just need to drop the WAR file in Tomcat/webapps folder and Tomcat will automatically deploy it during startup (or even while running, this is called hotdeploy).
If you want to develop without an IDE and/or don't want to create a WAR, then you just need to put a folder representing the context name in Tomcat/webapps, e.g. Tomcat/webapps/contextname. It will become the public web content. You can drop all JSP files and other static files in there. Then, for classes you need to create a Tomcat/webapps/contextname/WEB-INF/classes folder. There should go the package structure.
