| Projects for Virgo Tomcat Server are associated with a Virgo Virgo Tomcat Server runtime environment in Eclipse. This is to allow |
| launching and testing from within Eclipse, and also to allow classpath construction in Eclipse to |
| mirror the dynamic classpath in the Virgo Tomcat Server runtime. |
| </p><p> |
| Compilation errors in the previous step will be resolved here. |
| </p><p> |
| To configure a Virgo Tomcat Server runtime environment: |
| </p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p>Open <span class="guimenu">Window</span> → <span class="guisubmenu">Show View</span> → <span class="guimenuitem">Other???</span>.</p></li><li class="listitem"><p>In the <span class="emphasis"><em>Show View</em></span> dialog choose |

| </p></li><li class="listitem"><p>Click <span class="guibutton">Browse</span> and select the <code class="code">$SERVER_HOME</code> directory. Ensure that a JRE is selected |

| </p></li></ol></div><p> |
| It is possible that there remain spurious build errors from Eclipse (see the <span class="emphasis"><em>Problems</em></span> view), in which case |
| a project clean build may clear the problems. Select <span class="guimenu">Project</span> → <span class="guimenuitem">Clean???</span> |
| from the main menu, and choose to <span class="emphasis"><em>Clean all projects</em></span>. |
| It may be necessary to repeat this on a few projects. |
| (This process is sometimes known as the <span class="quote">“<span class="quote">Eclipse dance</span>”</span>.) |
| </p><p> |
| Despite the dance steps outlined, there will remain some <span class="emphasis"><em>Warnings/Errors</em></span> like this: |
| </p><div class="mediaobject" align="center"><img src="images/installing-greenpages/problem-warning.png" align="middle"></div><p> |
| It is safe to ignore these. |
| </p><p> |
| When the Virgo Tooling starts the Virgo Tomcat Server it uses a ‘warm start’ by default. |
| It is useful to set the <code class="literal">-clean</code> option so that every server start is a clean one. |
| This is done by an option on the Virgo Tomcat Server Overview window, which is obtained by opening the Virgo Tomcat Server entry in the Servers window. |
| (Double-click, or right-click and choose Open.) |
| The check box is labelled ‘Start server with -clean option’. |
| Close the window before proceeding. |
