The clean way to Uninstall JAVA is through SAPINST. 
Make user you drop only the JAVA Schema ID (SAPSR3DB)
If you want to uninstall manually, follow as mentioned below :
1. Stop the central services instance and all dialog instances of your SAP system:
a) Log on to the corresponding instance host as user <sapsid>adm.
b) Execute the following commands:
   To stop the central services instance:
             stopsap r3 <SCSinstanceName>
   To stop a dialog instance:
            stopsap r3 <DialogInstanceName>
2. Stop the J2EE Engine of the central instance:
a) Log on to your SAP system.
b) Call transaction SMICM.
c) Choose Administration J2EE Instance (local) Send Hard Shutdown
2. Drop the J2EE DB schema (the db schema for this one SAP SID) BE VERY CAREFUL, do not drop the DB schema for another existing system or
the ABAP schema.
a. Log on as user ora<dbsid>.
b. Start sqlplus and connect to the database. Enter:
sqlplus /nolog
c. SQLPLUS>connect / as sysdba
d. Enter the following command to delete the database objects of the database schema:
SQLPLUS> drop user SAP<SCHEMA_ID>DB cascade;
e. Enter the following command to get the file name of the corresponding data file in the file system:
SQLPLUS> select file_name from dba_data_files where \
tablespace_name = ’PSAP<SCHEMA_ID>DB’;
f. Enter the following command to delete the tablespace of the database schema:
SQLPLUS> drop tablespace PSAP<SCHEMA_ID>DB including contents;
g. Exit sqlplus:
SQLPLUS> exit
3. Remove folder "data" at: /sapmnt/QO1/global/security/data
4. Remove folder "SDM" at: /usr/sap/<sid>/<Central instance>/SDM
5. Remove folder "j2ee" at:  /usr/sap/<sid>/<Central instance>/j2ee
6. Revert CI instance profile to their original state (backup copies should exist) # they should be in the state before the start of the JavaAdd In
7. If lines beginning with the following parameters appear, delete these lines from the default profile, /usr/sap/<SAPSID>/SYS/profile/DEFAULT.PFL:
j2ee/dbname =
j2ee/dbtype =
j2ee/dbhost =
j2ee/dbadminurl =
j2ee/scs/host =
j2ee/scs/system =
j2ee/ms/port =
8. If lines beginning with the following parameters appear, delete these lines from the central instance pro?le and from all dialog instance pro?les,
/usr/sap/<SAPSID>/SYS/profile/<SAPSID>_<INSTANCE_NAME>_<host_name>:
exe/j2ee =
exe/jlaunch =
rdisp/j2ee_start_control =
rdisp/j2ee_start =
rdisp/j2ee_timeout =
rdisp/j2ee_libpath =
rdisp/frfc_fallback =
jstartup/trimming_properties =
jstartup/instance_properties =
jstartup/protocol =
jstartup/vm/home =
jstartup/max_caches =
jstartup/release =
j2ee/dbdriver =
9. Delete the central services instance
10. Restart ABAP and Install JAVA Add-in
