Java version on different users

Question

Hi,
OS:red hat 4.2
apps 11.5.10
Here we installed java *1.5, 1.4*
In applydev user,
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
. /ydev/u01/oracle/ydevappl/APPSORA.env
export PWR_TOP=/ydev/u01/oracle/ydevappl/pwr/11.5.0
OC4J_TOP=$PWR_TOP/oc4j
export OC4J_TOP
export LD_ASSUME_KERNEL=2.4.19
export PATH
unset USERNAME
[applydev@server2 ~]$
If we executed java -version
[applydev@server2 ~]$ java -version
java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) Server VM (build 1.5.0_15-b04, mixed mode)
if we executed only java ,we got the following output
[applydev@server2 ~]$ java
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-d32 use a 32-bit data model if available
-d64 use a 64-bit data model if available
-client to select the "client" VM
-server to select the "server" VM
-hotspot is a synonym for the "client" VM [deprecated]
The default VM is server,
because you are running on a server-class machine.
-cp <class search path of directories and zip/jar files>
-classpath <class search path of directories and zip/jar files>
A : separated list of directories, JAR archives,
and ZIP archives to search for class files.
-D<name>=<value>
set a system property
-verbose[:class|gc|jni]
enable verbose output
-version print product version and exit
-version:<value>
require the specified version to run
-showversion print product version and continue
-jre-restrict-search | -jre-no-restrict-search
include/exclude user private JREs in the version search
-? -help print this help message
-X print help on non-standard options
-ea[:<packagename>...|:<classname>]
-enableassertions[:<packagename>...|:<classname>]
enable assertions
-da[:<packagename>...|:<classname>]
-disableassertions[:<packagename>...|:<classname>]
disable assertions
-esa | -enablesystemassertions
enable system assertions
-dsa | -disablesystemassertions
disable system assertions
-agentlib:<libname>[=<options>]

see also, -agentlib:jdwp=help and -agentlib:hprof=help
-agentpath:<pathname>[=<options>]

[applydev@server2 ~]$
In another user abuabucker
bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
#. /ydev/u01/oracle/ydevappl/APPSORA.env
export PWR_TOP=/ydev/u01/oracle/ydevappl/pwr/11.5.0
OC4J_TOP=$PWR_TOP/oc4j
export OC4J_TOP
export JAVA_TOP=/usr/java/j2sdk1.4.2_04
export PATH
unset USERNAME
if we executed java -version
[abubucker@server2 ~]$ java -version
java version "1.4.2"

if we executed java only
we got the following output
[abubucker@server2 ~]$ 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.
where options include: this one is missing at abuabucker user.
so develop able to compile the program properly.
