SAP is not coming up after installing Java Add-in

Question

Hi,
I have installed a Java Add-in for an existing ABAP system. At the stage of "start J2EE engine" it is throwing an error message saying that Java is not coming up after 1142 seconds. I checked config tool and it is working fine. I restarted SAP. After restarting SAP, SAP is coming up and after 1 or 2 mins the disp+work is getting stopped and all the work processes are getting died. I couldn't able to understand & resolve the issue. The system is NetWeave 04. Here is the dev_w0 trace information.

Your profile parameters are messed up; check your instance profile has below parameters:
jstartup/trimming_properties = off
jstartup/protocol = on
jstartup/vm/home = /opt/java1.4
jstartup/max_caches = 500
jstartup/release = 700
jstartup/instance_properties = $(jstartup/j2ee_properties):$(jstartup/sdm_properties)
j2ee/dbdriver = $(DIR_EXECUTABLE)/db2jcc.jar:$(DIR_EXECUTABLE)/db2jcc_license_cu.jar
rdisp/j2ee_start_control = 1
rdisp/j2ee_start = 1
rdisp/j2ee_libpath = $(DIR_EXECUTABLE)
exe/j2ee = $(DIR_EXECUTABLE)/jcontrol$(FT_EXE)
rdisp/j2ee_timeout = 600
rdisp/frfc_fallback = on
icm/HTTP/j2ee_0 = PREFIX=/,HOST=localhost,CONN=0-500,PORT=5$$00
