I'm considering using Eclipse as an IDE for both PHP and Java development. I started by downloading and installing the "vanilla" (i.e. Java-oriented) version of Eclipse, and then tried adding the PDT add-on for PHP development, but I ran into all sorts of insoluble memory problems (OutOfMemory exceptions, PermGen and all that crud). So I then installed the PDT all-in-one bundle, and so PHP is now nicely setup with PHP perspectives etc., but now there doesn't seem to be any Java or Java EE capabilities in the IDE, and so I suspect that the Eclipse JDT (Java Development Toolkit) is not installed. My question now is - how do I go about installing the JDT add-on into my Eclipse environment? I've been Googling for hours now, but I can't find any trace of a hint as to where I can get the JDT component from. Is there a stable, combined PDT/JDT bundle available?
