They have created a very good product that is an improved HotSwap – it can swap structural changes as well. So you can develop web applications with Java almost as quickly as with any scripting language.įinally, I must mention one product with a slogan “Stop redeploying in Java” – JRebel. But that works perfectly fine – JSPs are refreshed by the servlet container (unless you are in production mode), and each view technology has an option for picking template files dynamically. You just can’t live without “save & refresh” there. But that, again, seems quite an ordinary scenario – your app can’t just load its bootstrapping configuration while running.Įven more common is the case with html & css changes.

You can’t hotswap configuration as well – your application is usually configured in some (.xml) file, so if you change it, you’d have to redeploy. Structural changes are more rare, and in some cases mean the whole application has to be re-initialized anyway. But “save & refresh” usually involves simply changing a line within a method. If you add a new class, new method, change the method arguments, add fields, add annotations, these can’t be swapped at runtime.

I’ve made a more extensive description of how to use them in this stackoverflow answer.

FileSync plugin for eclipse – configure it to send your compiled classes to an absolute path (where your tomcat lives).

WTP – configure the “Deployment Assembly” to send compiled classes to WEB-INF/classes.

With eclipse that can be done in (at least) two ways: So you just have to start the server in debug mode (the hotswap feature is available in debug mode) and copy the class files. The JVM has the so-called HotSwap – replacing classes at runtime. You can use “save & refresh” in java web applications as well. This quora question summarizes that “myth”. scripting languages, allow you to “save & refresh”. You don't need to stop and start Tomcat for this to work, but you can if you want.They say developing Java is slow because of the bloated application servers – you have to redeploy the application to see your changes. You will see a "sample" directory appear. Place the "sample.war" file in the "%CATALINA_HOME%\webapps" directory and Tomcat with automatically deploy it. If this is a redeployment, delete the existing deployment from the "%CATALINA_HOME%\webapps" directory. You can get a sample application WAR file to test with from " ". Logs : %CATALINA_HOME%\logs Deploying Applications The main locations of configuration and log information are shown below.

The management application is now available from the " URL.

Restart Tomcat for the configuration to take effect. The service can now be started and stopped from the Service dialog, or the command line.Ĭ:\> net stop "Apache Tomcat 7" Enabling HTML Management AccessĮdit the "%CATALINA_HOME%\conf\tomcat-users.xml" file, adding a new role and user with admin privileges. If you want you can set the environment variables before calling the command, but for a single installation of Tomcat, this is not necessary. From the command prompt, change directory to the "%CATALINA_HOME%\bin\" directory and run the following command. Running Tomcat as a service is very simple. The default page is visible on port 8080, so on the server itself you can access it using this URL " Remember to unblock the port on the firewall if you want to access the site from other servers on the network. You can now start and stop Tomcat using the following scripts. This directory is known as the CATALINA_HOME.Ĭreate a file called "D:\apache-tomcat-7.0.33\bin\setenv.bat" with the following contents, adjusted to your installation locations. In this case I unzipped it into the "D:\apache-tomcat-7.0.33" directory.
