Error when trying to emerge netbeans [SOLVED]

[Liox]

Hello,

I tried to install netbeans but I get an error at an pakage netbeans seems to depend on:

I checked all pakages mentioned at NV_DEPEND: and every single one is installed yet.
So what's wrong?
Any ideas?

I have checked this morning my java environment and it tells me:

* Checking generation_1_system_vm ...
* No Generation-1 System VM is set! (no /etc/env.d/20java)
* It doesn't look like java-config-1 sees any installed VMs.
* It is most likely because you don't have a 1.4 JDK installed
* This is required for generation-1 to work properly.
* You will want to emerge =virtual/jdk-1.4* [ !! ]

so I remerged virtual/jdk-1.4*, but it doesnt help.
if I call java-config-1 -L it shows me no jdk
I followed the instruction on the Gentoo Java Upgrade Guide but this helps either.
So I had a look at the wiki . The solution of the first problem tells me: Specifically, ensure that you have keyworded all the packages related to the new Java system. But what they mean with "keyworded" How do I keyword my java System?

Thanks for help...

So now I just reemerged blackdown-jdk and it installed an update to 1.4.2.03-r15. Now everthing seems alright. The java environment is in a sane state and the error disappeared. Now I have to install another 76 pakages. I hope this goes through without an error. Thanks for your reading.
