Question

在我的开发团队中，我们有框架和业务开发人员。

该框架已经是一个JEE6 webapp，业务开发人员使用该框架通过框架提供的Web界面构建他们的网页，并中调对业务服务的调用。

每个业务应用程序都构建为外部JAR文件，该文件将添加到tomcat启动类路径中。此外，它们是eclipse中的“Web Fragment Projects”（WFP），因为它也可以添加自定义JSP，HTML，CSS等等，还有一些使用web-fragment.xml。

到目前为止，这么好，在日食之外一切都很好......

在eclipse中，使用WFP和框架作为“动态Web项目”（DWP），一切都很好......

但是对于业务开发人员，我想在eclipse中创建Tomcat服务器并直接将其指向WAR并使其部署WFP。

我尝试在.launch文件中将WFP添加到classpath中，我还尝试在tomcat“VirtualWebappLoader”中添加bin dir，但是web-fragment.xml无法读取。

如何实现它的任何线索???

Ps：在eclipse外运行tomcat并远程调试WFP不是一种选择。

This is an old thread and it it seems I'm the only one with this scenario, but still, I would like to share the answer.

The WFPs are now Maven projects and the build output goes to /target/classes.
There is a normal wtp-tools web container (tomcat) pointing to a WAR file in file system.
Solution: I've kept with VirtualWebappLoader and added a new flag for JarScanner as shown below:


<Loader
className="org.apache.catalina.loader.VirtualWebappLoader"
virtualClasspath="apptest/target/classes;
customtest/target/classes"/>


<JarScanner scanAllDirectories="true" />

UPDATE

The ones using Tomcat 8 will notice the VirtualWebappLoader is no longer there. So take a look at Resources. It has been replaced by Pre, Jar and Post resources.

However, I didn't find a proper way to load an exploded Jar with META-INF/resources and META-INF/web-fragment.xml to WEB-INF/lib as required for Servlet 3.0 spec.

When using the proposed examples from Tomcat documentation and mapping exploded Jar directory to WEB-INF/classes everything seems to be 'OK', but META-INF/resources and web-fragment.xml declared elements are not available:

<div class="row">
    <div class="col-md-2"></div>
    <div class="col-md-6" id="form-container">
        <%= form_for @entry do |form| %>
            <br>
            <%= form.text_field :entry_title, :size => 59, :placeholder => "Entry Title"%>
            <br><br>
            <%= form.text_field :book_title, :size => 59, :placeholder => "Book Title"%>
            <br><br>
            <%= form.text_field :img_url, :size => 59, :placeholder => "Image URL"%>
            <br><br>
            <%= form.text_area :text, :placeholder => "Text" %>
            <br><br>
            <%= form.text_field :tag, :placeholder => "Tag" %>
            <br><br>
            <%= form.submit %>
        <% end %>
    </div>
    <div class="col-md-4"></div>
</div>

Then, changing webAppMount to "/WEB-INF/lib" give me some ClassNotFoundException in startup.

In the end, after several attempts I came up with a workaround:

<Resources>
  <PreResources
    className="org.apache.catalina.webresources.DirResourceSet"
    base="/home/reginaldosantos/apptest/target/classes"
    webAppMount="/WEB-INF/classes"
  /> 
</Resources>

Not too sure about that though.

Hope it helps some one ;-)
