SEF9 - 15 If you have problems with Java for openproj-1.4-2 installation

The following is how I solved my problem. openproj-1.4-2 works with java version 1.6 (JDK6) and not version 1.7. (JDK7). I have both installed. I made openproj-1.4-2 work successfully.

Wassalam.

CHECK JAVA VERSION (INITIALLY)
===========================================================
wruslan@wruslan-hpubuntu-rtai:~$ java -version
java version "1.7.0_10"
Java(TM) SE Runtime Environment (build 1.7.0_10-b18)
Java HotSpot(TM) Server VM (build 23.6-b04, mixed mode)

wruslan@wruslan-hpubuntu-rtai:~$ which java
/usr/bin/java
wruslan@wruslan-hpubuntu-rtai:~$

EXISTING JDK7 LIBRARIES.
===========================================================
/usr/lib/jvm/jdk1.7.0/bin
/usr/lib/jvm/jdk1.7.0/jre

Need to install JDK6 because openproj_1.4-2 does not run with JDK7 above.

Cannot remove or overwrite JDK7 because other new applications depend on it.

So, we install JDK separately from JDK7 on the same computer. Ha ha ha.

INSTALL JDK6 (/usr/java/jdk1.6.0_29/bin) USING jdk-6u29-linux-i586.bin (downloaded)
