Eclipse Juno JSP syntax highlighting doesn't work

问题

I installed the Java EE version of Juno and opened an existing project I'm working on. First thing I noticed was that there was no syntax highlighting on my JSP's. I checked my install and I do have WTP installed.

Any ideas why this isn't working? It has worked out-of-the-box on every other version of Eclipse that I've used.

Same problem happen to occur for me. I had tried this solution and it worked for me.

1. Check your JDK must be 1.6 or later. If not install JDK 1.7

2. If problem still persists, In Eclipse Go to Help -> Install New Software -> WorkWith (Select Juno - http://download.eclipse.org/releases/juno) -> Expand Web, XML, Java EE and OSGi Enterprise Development -> Web Page Editor (Check it) and install it.

   Restart eclipse after installing. Now open a existing jsp file with Web Page Editor. To do this right click on jsp file open with -> Web Page Editor. If Web Page Editor is not present go to Other -> Internal Editors -> Web Page Editor Or Go to new file create with .jsp extension and open with web page editor

   Now in Eclipse Goto Window -> Preferences -> General -> Editors -> File Associations Select *.jsp and make web page editor as default editor

3. Create a shotcut for *Eclipse *on desktop and right click on shortcut go to properties->shortcut tab -> target

   In the target add these line in braces (-vm "path for your bin folder of jdk 7") For Example target should look like "C:\eclipse\eclipse.exe" -vm "C:\Program Files\java\jdk1.7.0_06\bin"
