How to delete this for Java

[tech291083]

Hi,

Just installed JDK with netbeans and tried the following

[root@localhost ~]# alternatives --config java

There are 2 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
*+ 1           /usr/lib/jvm/jre-1.4.2-gcj/bin/java
   2           /pathto/sunjava/java

Enter to keep the current selection[+], or type selection number:

Now how do I delete the first one here ie /usr/lib/jvm/jre-1.4.2-gcj/bin/java which is no longer needed as JRE has been deleted manually be me only. Thanks...

Just ignore the previous post here is the latest update.

Just installed JDK 6u1 with NetBeans 5.5.1 from here

http://java.sun.com/javase/downloads/index.jsp

and tried the following

[root@localhost ~]# alternatives --config java

There are 2 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
*+ 1           /usr/lib/jvm/jre-1.4.2-gcj/bin/java
   2           /pathto/sunjava/java

Enter to keep the current selection[+], or type selection number:

Do I need to delete any of these two at all?

I did install JRE separately previously and deleteted manually with rpm -e since JDK 6u1 with NetBeans 5.5.1 has got JRE built into it already.

I also changed the path as Java was not being compiled in the terminal at all. This is what I did, not sure if it is right thing to do, but it does now compile Java programs in the terminal as long as the pc is on.

[root@localhost opt]# cd /opt/jdk1.6.0_01/bin
[root@localhost bin]# export PATH=/opt/jdk1.6.0_01/bin:$PATH

This is another piece of info:

[root@localhost ~]# whereis netbeans
netbeans: /opt/netbeans-5.5.1/bin/netbeans
[root@localhost ~]# cd /opt
[root@localhost opt]# ls
jdk1.6.0_01             jre-6u1-linux-i586-rpm.bin  netbeans-5.5.1
jre-6u1-linux-i586.rpm  libjavaplugin_oji.so
[root@localhost opt]#

One thing here is strange, libjavaplugin_oji.so is flashing in a red background. Is it some kind of error that needs to be corrected? Looks like a broken link to me though.

Thanks...

The first is not the JRE it is the gcc version of Java. I would uninstall it if I were you, because JDK is better for you as a programmer.

What does the verb figure out mean? (My English is not very good).

Apolozies,

I mean how did you work it out ie conclude or decide.

If you look at the two alternate paths you can see the gcj on the first one. I think that is the gcc version of Java.

Excellent, thanks...
