Please check the attached report for more information
131_19-b02-report.tar.Z is for 131_19-b02 execution

Master WS is at:
/net/urts071.india.sun.com/export6/testSuites/1.3.1/awt
Steps to execute with JTREG:
-----------------------------
1.
Copy the awt WS to a local machine (or) to a share location in server(Where Samba is running)
WS can found in :
/net/urts071.india.sun.com/export6/testSuites/1.3.1/awt
2.
 Touch a TEST.ROOT at the very top level -- same level of all test suite.
3.
 Set the environment variable JAVA_HOME to proper jdk.
4.
Set the environment variable JTREG_HOME to proper JTREG Platform script file
For Ex : export JTREG_HOME=/net/urts071.india.sun.com/export2/tools/sqe-tools2.1.6fcs/solaris
5.
sh runauto.ksh
6.
In the JavaTest GUI select the Test Parameter tab
7. Under Which tests to Run
Add only the above two testcases
8.Select Test Execution Status tab and click on Start button to run the tests


Steps to execute without JTREG
------------------------------
1.
Copy the awt WS to a local machine (or) to a share location in server(Where Samba is running)
WS can found in :
/net/urts071.india.sun.com/export6/testSuites/1.3.1/awt
2. Go to the failed test case location
For Ex.
CD to <131-awt-WS>/Focus/src/automated/LightWeight/KeyEventtoComponent
3.
Compile the java files with 131_19-b02 jdk
4
Execute the html file to load the applet
For Ex:
<131_19-b02-JDK>/bin/appletviewer KeyEventtoComponentTest.html

Note :
to compile and execute you need awtsqe.jar on CLASSPATH
awtsqe.jar file is available on the 131-AWT WS
It is available on
/net/urts071.india.sun.com/export6/testSuites/1.3.1/awt/awtsqe.jar
