## 9.7 FAQ

- How do I turn on (or turn off) automatic Manifest generation? (Bundlor)

Bundlor is not used by default, you must create you own template file and then turn on incremental manifest generation. Right-click your Virgo project, select the Virgo subcategory from the context menu and select Enable (or Disable) Incremental Generation of MANIFEST.MF File. You can also modify this setting from the Overview page of the Bundle Manifest Editor, under the Bundle Actions section.

- Sometimes I'd like to automatically update my Manifest without having to turn on the automatic Manifest setting. How can I do this?

Right-click your Virgo project, select the Virgo subcategory from the context menu and select Run Generation of MANIFEST.MF File. This command has a keybinding that you may customize through Eclipse's Keys preferences. You can also perform an automatic update of the Manifest from the Overview page of the Bundle Manifest Editor, under the Bundle Actions section.

- Automatic Manifest generation doesn't appear to picking up changes to my source files.

Sometimes Manifest generation may behave differently depending on whether the tools are configured to scan source folders or to scan output folders. To modify this setting right-click your Virgo project, select properties and select the Virgo -> Manifest Generation subcategory. If Manifest generation isn't working correctly for you, uncheck the "Scan output folders instead of source folders to generate MANIFEST.MF" setting and re-run the Manifest generation. If your Manifest is not being properly generated under either setting, please file a bug.

- My Virgo project is validating its dependencies against the wrong Virgo runtime! How do I manage server runtimes for my Virgo projects?

If you've deployed your Virgo projects to multiple Virgo runtimes the tools will associate the project with each runtime, but will only validate against one runtime. In order to manage which Virgo runtime your bundle dependencies are validated against, right-click on the project, select Properties and select the Targeted Runtimes category. From this dialog you can give priority to a particular Virgo runtime.

- How do I deploy a Plan with the Virgo tools?

Deploying a Plan works much the same way as deploying a Bundle or PAR from the tools. Unfortunately, the tools only handle Plan deployment correctly when the Plan refers to items already in Virgo's watched repository directories. If you try to deploy a Plan that references a project in the Eclipse workspace, the tools will fail. One workaround is to copy your workspace bundle(s) into repository/usr or some other watched repository directory. A discussion of this bug and other workarounds is available at https://bugs.eclipse.org/bugs/show_bug.cgi?id=379765

- How do I create a Web Application Bundle?

To create a web application bundle choose to create a normal bundle project, but on the Bundle Content panel select the additional property entitled "Web Application Bundle". On the Bundle Properties panel enter a suitable context path for the application as the Web-ContextPath.

- How do I export a Web Application Bundle (WAB)? Export -> Bundle Project produces an incorrect product.

To export a WAB invoke Export -> Web -> WAR File

- Virgo Jetty Server (VJS) does not startup correctly and I see a 503 error when I go to http://localhost:8080/admin

This can happen after starting VJS clean because VJS is looking for a directory at $KERNEL_HOME/work/tmp but no tmp directory exists. A workaround is to start VJS from the command line without the -clean command, which will create the tmp directory. VJS can then be used from the tools. This bug and workaround are documented at https://bugs.eclipse.org/bugs/show_bug.cgi?id=384288

- Can I get a deeper look into the state of the server from the Virgo Tools?

Yes! If you double-click a Virgo server runtime in the Servers view, you'll open up the server editor, with several pages of information. The Repository, Bundle Overview, Bundle Dependency Graph, and Server Console pages all give valuable insight into the state of the server. The Virgo perspective also provides several views into the Virgo Repository, Virgo Properties and Virgo Logs. See the Virgo Tooling Guide for more information.

- I want to install Virgo Tools. Should I install all of this neat looking stuff under Virgo Add-ons?

We really don't recommend doing so (see Install_Virgo). Select only Virgo Tooling and Eclipse will take care of installing anything the tooling relies on.

- Can I use the Virgo Tools with traditional PDE/Equinox Bundles?

Deploying PDE/Equinox Bundles to Virgo Web Server are not yet supported yet, although exporting the bundles (as Eclipse Plug-in JARs) and manually deploying to Virgo Web Server works. Please show your support on Bugzilla #329198.
