The Visual Page Editor requires the library libstdc++.so.5. This library is contained in the compat-libstdc++-33.i386 package.
To install this package on Fedora Core or Red Hat Enterprise Linux run the following command:
yum install compat-libstdc++-33.i386On any other rpm based distributions download
libstdc++.so.5and run the following command:rpm -Uvh compat-libstdc++-33.i386On Debian based distributions run the following command:
apt-get install compat-libstdc++-33.i386
In case you have the library installed and you still have issue with starting the Visual Page Editor then close all browser views/editors and leave one Visual Page Editor open and restart eclipse. This should force a load of the right XULRunner viewer.
If it doesn't help and you use Fedora Core Linux and Eclipse Version: 3.4.1, the issue can be produced because 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:
Decompress
eclipse/plugins/org.eclipse.swt.gtk.linux.x86_3.4.1.v3449c.jarfromeclipse-SDK-3.4.1-linux-gtk-x86_64.tar.gzCopy
libswt-xulrunner-gtk-3449.sofile to your Fedora Eclipse location.Open the file eclipse.ini,which can be found in your Fedora Eclipse location and add the following line:
-Dswt.library.path=/usr/lib/eclipse,where
/usr/lib/eclipseis the path to your eclipse folder.
JBoss HTML/JSP editor uses basic eclipse HTML formatter to format files. So if you want to change preferences of formatter for the Visual Page Editor, you should change it for eclipse html editor (open → then choose → → ).
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 → 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.
