First we make sure that the backport repository is available in our sources.list |
| |
|
6 |
|
| |
|
7 |
Use your favourite text editor to open up the sources.list. |
| |
|
8 |
|
| |
|
9 |
*sudo vim /etc/apt/sources.list |
| |
|

If you also would like to install the [Eclipse] IDE, then make sure the universe repository is available on the sources.list file. |

Save the sources.list. |
| |
|

|

Now we need to update our list of available packages from the apt sources. |
| |
|
28 |
|
| |
|
29 |
*sudo aptitude update |
| |
|
30 |
|
| |
|
31 |
Now we download and install Java 1.6. |
| |
|
32 |
|
| |
|
33 |
*sudo aptitude install sun-java6-jdk |
| |
|
34 |
|
| |
|
35 |
There is a fair bit to download so hopefully you are no longer using dial-up :) |
| |
|
36 |
A few license agreements will pop-up, just choose OK. |
| |
|
37 |
|
| |
|
38 |
Now that is done we need to make sure that we are using the correct version of java. |
| |
|
39 |
|
| |
|
40 |
*sudo update-alternatives --config java |
| |
|
41 |
|
| |
|
42 |
You will see a few alternatives. Select the option that has ''java-6-sun'' in the java path. |
| |
|
43 |
|
| |
|
44 |
Now we will do the same thing for the compiler: |
| |
|
45 |
|
| |
|
46 |
*sudo update-alternatives --config javac |
| |
|
47 |
|
| |
|
48 |
Once again select the alternative with ''java-6-sun'' in the path. |

| |
|
55 |
|
| |
|

| |
|
57 |
|
| |
|
58 |
Head to your workbench and then ''File --> New --> Project'' |
| |
|
59 |
Choose ''java project''. and click next. |
| |
|
60 |
|
| |
|
61 |
!In the ''JRE'' section, if your default is not set at ''java-6-sun-1.6.0.00'' |
| |
|
62 |
Click ''configure JREs'' |
| |
|
63 |
Click the add button and browse to ''/usr/lib/jvm'' |
| |
|
64 |
Choose ''java-6-sun-1.6.0.00'' (There may be some other symbolic links you can choose also) and click OK. |
| |
|
65 |
Make sure that java-6-sun-1.6.0.00 has a tick next to it. |
| |
|
66 |
|
| |
|
67 |
Good now we will set up the JDK compliance Level. |
| |
|
68 |
Click the dropdown box next to the text ''compiler compliance level'' and choose 6.0. |
| |
|
69 |
Click OK. |
