Eclipse - Glassfish - Struts 2.x


(Todd Gerspacher) #1

I am trying to get a simple Struts 2.x project to run in Eclipse (using Glassfish 3.1.2.2). I started with a copy of a working project and deleted all the Eclipse generated files (ie. the “.settings” directory, and the “.classpath” and “.project” files). Here’s what my build looks like:

apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'eclipse-wtp'
  repositories {
    mavenLocal()
    mavenCentral()
}
  dependencies {
    compile 'org.apache.struts:struts2-core:2.3.8'
}
  sourceSets {
    main {
        java {
            srcDirs "src"
        }
          resources {
            srcDir "src"
        }
    }
}

When I go to add the project on the Eclipse server tab, I get a pop up that says: “There are no resources that can be added or removed from the server.”

What am I doing wrong?

Although my Struts app still isn’t running correctly, I was able to solve the above problem that I had. It had to do with the generated .settings/org.eclipse.wst.common.project.facet.core.xml file. When I added the following to my build script, I am able to add the project on the Eclipse server tab.

eclipse {
  wtp {
    facet {
        facet name: 'java', version: '1.7'
      facet name: 'jst.web', version: '3.0'
      facet name: 'sun.facet', version: '9'
      facet name: 'wst.jsdt.web', version: '1.0'
          file {
        withXml {
          def node = it.asNode()
            node.appendNode('runtime', [name: 'GlassFish 3.1.2 2'])
          node.appendNode('fixed', [facet: 'wst.jsdt.web'])
          node.appendNode('fixed', [facet: 'java'])
          node.appendNode('fixed', [facet: 'jst.web'])
        }
        }
    }
  }
}

Found that the other problem is with the generated org.eclipse.wst.common.component file in the .settings folder. I copied the line from EclipseWtpComponent DSL for adding a wb-resource element, but it doesn’t appear in the component file. Here’s my eclipse block so far:

eclipse {
  wtp {
    facet {
      // you can add some extra wtp facets; mandatory keys: 'name', 'version':
      facet name: 'java', version: '1.7'
      facet name: 'jst.web', version: '3.0'
      facet name: 'sun.facet', version: '9'
      facet name: 'wst.jsdt.web', version: '1.0'
        file {
        //if you want to mess with the resulting XML in whatever way you fancy
        withXml {
          def node = it.asNode()
          node.appendNode('runtime', [name: 'GlassFish 3.1.2 2'])
          node.appendNode('fixed', [facet: 'wst.jsdt.web'])
          node.appendNode('fixed', [facet: 'java'])
          node.appendNode('fixed', [facet: 'jst.web'])
        }
      }
    }
      component {
      resource sourcePath: 'extra/resource', deployPath: 'deployment/resource'
    }
  }
}

Okay, so like I was going about this the wrong way. I still needed to added a couple of wb-resource elements to the generated org.eclipse.wst.common.component file, but its not as bad as the last two posts make it sound. Here’s the build script that I used:

apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'eclipse-wtp'
  repositories {
 mavenLocal()
 mavenCentral()
}
  dependencies {
 compile 'org.apache.struts:struts2-core:2.3.8'
}
  eclipse {
  wtp {
    component {
      resource deployPath: '/', sourcePath: '/WebContent'
      resource deployPath: '/WEB-INF/classes', sourcePath: '/src'
    }
  }
}
  sourceSets {
    main {
        java {
            srcDirs "src"
        }
   resources {
  srcDir "src"
 }
    }
}

Note: This requires that a src and WebContent folder exists in the project’s directory.

Next I ran the eclipse task and then imported the project into Eclipse. I then right clicked on the project, selected Project Facets and clicked on the Runtimes tab. I put a check mark on the GlassFish runtime. I also selected the “Default Configuration for GlassFish” from the Configuration drop down box. Click ok and it runs.
