Updating a file using a file "file" for the chef

I am trying to install java using chef-solo. The problem is to set the variables JAVA_HOMEand PATHfile /etc/profile. I tried to use the resource 'file'provided by the chef. here is my code:

java_home = "export JAVA_HOME=/usr/lib/java/jdk1.7.0_05"
path = "export PATH=$PATH:/usr/lib/java/jdk1.7.0_05/bin"

execute "make_dir" do
  cwd "/usr/lib/"
  user "root"
  command "mkdir java"
end

execute "copy" do
  cwd "/usr/lib/java"
  user "root"
  command "cp -r /home/user/Downloads/jdk1* /usr/lib/java"
end

file "/etc/profile" do
  owner "root"
  group "root"
  action :touch
  content JAVA_HOME
  content PATH
end

but the problem in the command contentcancels the entire contents of the file, is there a way to UPDATE the file when using chef-solo resources. Thank!

UPDATE: I found the code from chef-recipe, but I'm not sure what it does exactly, the code ...

ruby_block  "set-env-java-home" do
  block do
    ENV["JAVA_HOME"] = java_home
  end
end

Does the JAVA_HOME variable set only for this instance or permanently? Can anyone help?
