Sysdeo Tomcat Launcher Plugin


Plugin features

  • Starting and stopping Tomcat 4.x, 5.x and 6.x

  • Registering Tomcat process to Eclipse debugger

  • Creating a WAR project (wizard can update server.xml file)

  • Adding Java Projects to Tomcat classpath

  • Setting Tomcat JVM parameters, classpath and bootclasspath

  • Exporting a Tomcat project to a WAR File

  • Capability to use a custom Tomcat classloader to load classes in several java projects at the same classloader level than classes in a Tomcat project, see readmeDevLoader.html


  • This plugin does not contain Tomcat.
    (Download and install Tomcat before using this plugin).
    This is a design choice not to include Tomcat in the plugin distribution, this way the same plugin version can works with any Tomcat version.

  • Download

  • Unzip it in your_Eclipse_Home/plugins

  • Plugin activation for Eclipse 3.x :
    - launch eclipse once using this option : -clean
    - if Tomcat icons are not shown in toolbar : select menu 'Window>Customize Perspective...>Commands', and check 'Tomcat' in 'Available command groups'

  • Set Tomcat version and Tomcat home : Workbench -> Preferences, select Tomcat and set Tomcat version and Tomcat home (Tomcat version and Tomcat home are the only required fields, other settings are there for advanced configuration).

  • This plugin launches Tomcat using the default JRE checked in Eclipe preferences window.
    To set a JDK as default JRE for Eclipse open the preference window : Window -> Preferences -> Java -> Installed JREs.
    This JRE must be a JDK (This is a Tomcat prerequisite).

  • The plugin sets itself Tomcat classpath and bootclasspath. Use Preferences -> Tomcat ->JVM Settings, only if you need specific settings.

Documentation and tutorials

Official documation (french) :

Tutorials (english) :


  • In some case, despite it is correctly unzipped in Eclipse 3 'plugins' directory, the plugin is not loaded : run Eclipse with the -clean option to solve the problem.

  • ClassNotFound when using DevLoader and launching Tomcat 5.5.12 and above
    Workaround : set context definition mode (Preferences->Tomcat) to 'Context files'.
    Explanations :
    This problem is due to a change in Tomcat 5.5.12 and above ( ,)
    We hope this bug will be fix but it seems that Tomcat developers don't care about it because it happens when a context containing its own loader is defined in server.xml file and since Tomcat 5 defining context in server.xml is not recommended)

  • ClassNotFoundException on javac/Main when accessing JSP : Tomcat is started with a JRE instead of a JDK.

  • If you have a problem with the plugin check eclipse log file (<%Your_Workspace_dir%>/.metadata/.log)
