error messages in eclipse IDE when opening .php and .tpl files

Been using eclipse for a short while. I run ubuntu 10.10 and have installed Eclipse web tools platform plug-ins for ecplise and the php development tools plug-in, when I started a 开发者_Python百科php project I also installed the php perspective, but this doesn't work when I run php files?!

I get this error

Unsupported content type in editor

So when I edit php files I use the Java perspective. This works. I can't say that eclipse impress much with all these weird errors when I install every thing by default and are only doing simple tasks, like editing a php file with a php editor..

I also get this error when I open .tpl files (smarty template engine files)

Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.

Thats my main problem.

I had the same error namely: Unsupported content type in editor

And solved it this way: You need to open it in navigator (window -> show view -> navigator) not the php perspective or project view or anything else.

At least this worked for me hope it also helps you!

After doing the file association,You need go to preference general > content type > Text and add extension For example , I need *.tpl to be open in HTML editor, than I can do like below.

This seems to be related to your JRE installation.

See those two forum threads:

Reasons could be manifold.

Most popular: You're running Apollo for Eclipse with JRE version < 1.5. Look for a line saying java.vm.version=xxx in Help->About Eclipse SDK->Configuration Details
