Java installation

techdawg270 · #1 5th July 2007, 10:28 PM

Did this installation go as planned? I had my doubts due the the 33%, 50%, and all those percentages that are not 100% near the bottom.

This looks fine. After each RPM is installed, the overall job % is updated, and newline/progress
bar starts for the next rpm.

}

My next question is when I download and install Eclipse now, will it automatically know where the kit is and how to go about using it's various classes? Or is this something I must configure myself? I have only used JCreator and Eclipse on Windows so this is all new to me.

@Nothing: The java you're using is linked to the gcj version, which quite frankly, sucks (not your fault). Here's a guide: http://news.softpedia.com/news/How-t...-6-39724.shtml

@tech: I'm sure there's ways to change it if eclipse can't find it.

Hopefully once jdk 1.7 comes out, fedora will replace gcj with that.

humm de guild talking about JRE not JDK...

so am better to instal the JDK 5 ??

giulix · #7 11th July 2007, 04:48 PM

Why not install the latest JDK instead ? In Eclipse go to Window->Preferences->Java->Installed JREs and change the settings there. Same as windoze

Try:

Code:

java

If you get the following, that is Redhat's Java, kinda lame.

Code:

[marc@kiriyamablevins ~]$ java
Usage: gij [OPTION] ... CLASS [ARGS] ...
          to invoke CLASS.main, or
       gij -jar [OPTION] ... JARFILE [ARGS] ...
          to execute a jar file
Try `gij --help' for more information.

No. As long as the java and javac command paths are specified for Sun's JDK, then installing gcj won't give you problems.

ok, tanks alot =)
in witch file i sould verify the path ?
