downloaded WTP complete non-SDK, have no J2EE perspective [message #200521]

I'm trying to get the features/plugins to get web projects. I'm using
Eclipse 3.3 and I just downloaded the 2.0 non-SDK Web Tools Platform
Complete zip. The way it is described there is exactly what I want to do;
develop web applications. I don't care about developing more tools.

I unzipped it into my eclipse directory and restarted eclipse. There are
no options to create a new web project, nor is there a J2ee perspective.
When I look at the Eclipse features, I see JST and WST both listed there.
So what am I missing? How do I get the J2EE perspective and web projects?

I've had this working at my previous job, not sure what I've done
different this time.

Thanks

The most common cause of this is running Eclipse in a 1.4 VM. WTP
plugins require a 5.0 VM. You can force Eclipse to use a particular VM
by adding a "-vm <path>" option to the eclipse.ini file.

Thanks for your reply. I tried this and it's not working. I added the
following to eclipse.ini :

-vm
C:\Sun\SDK\jdk\bin\java.exe

I tried many permutations of this, including javaw.exe instead, and doing
it all on one line with quotes around it, based on different
articles/posts I found.

But I'm confused by sun's versioning. I downloaded J2EE 5 earlier and
installed it into the default location, which is C:\Sun\SDK. During the
install I noticed '1.6' a couple times. I changed my JAVA_HOME to
C:\Sun\SDK\jdk. When I run java -version from the command line, it says
1.6!

What next?

I believe that the path you need to specify for the -vm parameter is the
root dir of the jdk install, so you would want to write something like:

-vm C:\Sun\SDK\jdk

Regarding the versioning, a 1.6 VM should be fine as well. The J2EE
distributions lag behind the J2SE (base technology), so you can find a
J2EE 5.0 distribution based on a 6.0 J2SE VM.

I tried this as well, still not working.

Is there something else I need to do to somehow enable the WTP features,
once the VM change has been made? I've gone into help->software
updates->Manage Configuration and JST and WST are both listed there as
enabled. The way I've been checking if this is working is trying to open a
J2ee perspective, and/or create a web project. Neither option is available.

Brian,

You were correct about the -vm parameter. I almost always specify this
parameter, and it should be the full path of java.exe or javaw.exe. You
might try temporarily adding "-debug" and "-clean" on separate lines
just above the -vm line in your eclipse.ini. After starting/restarting
Eclipse, check the Error Log view for "bundles which are not resolved".
The info available may allow you to determine if some requirement in a
WTP plug-in dependency chain is not being met.

Cheers,
Larry
