Refer to the following FAQ to get the answers on the most "popular" questions concerning JBoss Developer Studio.

7.1. What should I do if the Visual Page Editor does not start under Linux

Linux users may need to do the following to get the Visual Page Editor to work correctly on their machines.

On Red Hat based Linux distributions install the libXp.i386 package

ln -s libstdc++.so.5.0.7 libstdc++.so.5

and/or use
```
yum install libXp
```
Open the JBDS perspective. If you see the Help view open, close it and restart JBDS
If it doesn't help and you use Fedora with Eclipse Version: 3.4.1, the issue can be produced because the libswt-xulrunner-gtk-3449.so file doesn't present in eclipse-swt-3.4.1-5.fc10.x86_64.rpm/eclipse/plugins/org.eclipse.swt.gtk.linux.x86_64_3.4.1.v3449c.jar. To add this file to eclipse you should:
If none of these work, do the following:

7.2. Visual Editor starts OK, but the Missing Natures dialog appears

Figure 7.1. Missing Nature

Some functionality of Visual Editor may not work if a project doesn't have org.jboss.tools.jsf.jsfnature or org.jboss.tools.jst.web.kb.kbnature in .project configuration. To fix this problem and turn off the message box execute next steps:

Right mouse button click on a project in Package Explorer.
Select Configure → Add JSF Capabilities from the context menu.
Configure your project using Add JSF Capabilities wizard and press Finish.

If you are sure that your project does not need JSF capabilities, just disable this message box by checking Do not show this dialog again! checkbox.

7.3. Do I need to have JBoss Server installed to run JBoss Developer Studio?

No. JBoss Developer Studio already comes bundled with JBoss Server. We bundle it together so that you don't need to download any additional software and can test your application in a Web browser right away.

If you want to use a different JBoss server installation, after JBoss Developer Studio is installed open Servers View (select Window → Show View → Others → Server → Servers), then right click and select View → New → Server and follow the wizards steps to point to another Jboss Server installation.

JBoss Developer Studio works with any servlet container, not just JBoss. For more information on deployment, please see the Deploying Your Application section.

7.4. I have an existing Seam 1.2.1 project. Can I migrate or import the project into a JBDS Seam project?

Use the following steps to manually transfer an existing Seam 1.2.1 project into a new JBDS Seam project:

Create a Seam Web project to get the JBoss tools structure

Then from your Seam 1.2.1 seam-gen project start doing the following:

Copy src to src
Copy view to Web content
Copy resources individual files to where they are in the seam web project etc.

7.5. I have an existing Struts or JSF project. Can I open the project in JBDS?

Yes. From main menu select File → File → Import → Other → JSF Project (or Struts Project) and follow wizards steps.

7.6. Can I import a WAR file?

Yes. Select File → Import → Web → WAR file then follow importing steps.

7.7. Is it possible to increase the performance of Eclipse after installing your product?

JBoss Developer Studio preconfigures eclipse via the eclipse.ini file to allocate extra memory, but if you for some reason need more memory then by default, you can manually make adjustments in this file. For example:

-vmargs -Xms128m -Xmx512m -XX:MaxPermSize=128m

7.8. How can I add my own tag library to the JBoss Tools Palette?

See the section on Adding Tag Libraries in the Visual Web Tools Guide.

7.9. How to get Code Assist for Seam specific resources in an externally generated project?

To get Code Assist for Seam specific resources in an externally generated project, you should enable Seam features in Project Preferences. Right click an imported project and navigate Properties → Seam Settings. Check Seam support box to enable all available Seam Settings.

7.10. How to import an example Seam project from jboss-eap directory?

To import an example Seam project from jboss-eap into your working directory, you should perform the following steps:

Select New → Other → Java Project from Existing Buildfile
Point to the build.xml file of any chosen project by clicking the Browse button
Click the Finish button to open the project

As these seam examples are non WTP projects, next you should enable Seam support for them. To do that, right click the project and select Properties → Seam Settings.

7.11. Is a cross-platform project import possible for JBDS?

Yes. You can easily import created in Linux JSF, Struts or Seam project to Windows and vice versa.

To do the transferring JSF, Struts or Seam project, select Menu → Import → General → Existing Projects into Workspace.
