Various Internet Explorer IE versions script error dialog boxes

Internet Explorer 3.x and 4.x display a rather confusing (from the user point of view anyway) error message for script errors:

Internet Explorer 5 improves the situation somewhat by hiding the default error dialog box, and instead displaying a warning icon and text message in the status bar after the page loads:

Inquisitive Internet Explorer 5 users can double-click the status bar to display an updated default error dialog box (note how it displays the first time the user encounters a script error on a Web page, but requires the user to check the check-box in order to always display it):

In IE8, we’ve given the script error dialog a visual refresh (it needed it—compare IE7 vs. IE8 below). We think we’ve really improved the readability of the dialog, and made it simpler to see multiple script errors. We also listened to the number one customer request, which was to add copy/paste support to this dialog. As a result, Ctrl+C will copy all of the errors to the clipboard, whether the dialog is in its expanded state or not, and individual errors can be copied in the same manner after they’ve been selected. The dialog also supports an XML output to the clipboard if SHIFT is held while copying.

Information copied from the script error dialog can be used as feedback to help web sites and support personnel to quickly find and diagnose errors, improving the usability of the site for all visitors.

How to convert Java Project to Web Project in Eclipse Ganymede, Europa

Sometime we just need to convert our Java Project to Web Project in Eclipse IDE.

Here is some of the reasons you may need to convert Java Project to Web Project

1) Create / import a wrong project type
2) Initial java project migrate to java web project
3) Maven create a Java Project (eclipse:eclipse), but we need a web project feature.
4) Others…?
No mater what reasons we need to convert java project to web project. Eclipse does not provide a feature to convert it automatically. We have to do it manually.

Here is the steps to convert Java Project to Web Project in Eclipse

1) Create a empty dynamic web project and click on the .project file
2) Copy “web project” facet buildCommand and paste within “java project” .project buildSpec tag

<buildCommand>
  <name>org.eclipse.wst.common.project.facet.core.builder</name>
  <arguments>
  </arguments>
 </buildCommand>

3) Copy “web project” facet nature and paste within “java project” .project natures tag

<nature>org.eclipse.wst.common.project.facet.core.nature</nature>

P.S Be careful of the .project xml tag, make sure you paste into a correct location.
4) Save it.
5) Right click on Java Project, click properties.
6) Select Project Facets and click modify project button.
7) Click Dynamic Web Module and Java check box.
