Hello:

Subject: Eclipse as a development environment with Jakarta Tomcat
—————————————————————————-

I am setting up the new development environment for my application (project). Below are the components involved::

• Eclipse 3.1
• myEclipse – EnterpriseWorkbenchInstaller_4.0GA_E3.1
• jakarta-tomcat-5.0.28 (Application Server)
• Sysdeo Eclipse Tomcat Launcher plugin – tomcatPluginV31beta
• SDK 1.4.2_08
• Microsoft XP sp2 operating system

I have no issue with creation of project structure in eclipse IDE, compilation, and deployment, but there are some exception upon running the application.

My project folder structure as follows:
——————————————

MyApplication/
src/
Conf/
Web/
classes
taglib
lib
web.xml

• my application has few dependent projects, therefore I copied all the dependent projects final compiled classes (jars) to ‘lib’ folder.
• I set all necessary classpath according to tomcat documentation.
• I created MyApplication.xml file under D:\jakarta-tomcat-5.0.28\conf\Catalina\localhost\ folder with the below context

<Context path=”/MyApplication ” docBase=”D:/xx/xxx/dev/src/ MyApplication/web” debug=”0″ reloadable=”true” />

• I don’t get any exception during compilation and deployment process.
• I would greatly appreciate if you could give me a tips!!!!!!!!!!!!!!!!!!!!!!

Error as follows:

Mohamed,

• Sysdeo Eclipse Tomcat Launcher plugin – tomcatPluginV31beta

Sorry, but we can’t provide support on plugins from other sources. Also, you don’t need this plugin
to setup Tomcat with MyEclipse and its presence would likely be quite confusing since there is some
feature overlap.

To get going, I’d highly recommend that you start with a clean Eclipse 3.1.1 / MyEclipse 4.0.2 installation
and then read the “Using Application Servers” and “Working with Web Projects” quickstarts from our
documentation section here: http://www.myeclipseide.com/ContentExpress-display-ceid-67.html

That will give you the basic information you need to configure and run an application in Tomcat using
MyEclipse. Once you’ve run a test application or two, you’ll have the knowledge about how things work
to set up your specific project.
