 Background:

VistALink is a utility provided by the VA to allow JAVA applications to execute Remote Procedure Calls (RPC) on the VistA/M server.

Environment: Ubuntu 7.04 (Feisty Fawn) JDK 1.5.0_12 J2EE SDK 5.02 VistA Office EHR SemiViva 2.3.1 VistALink 1.5 (Listener is already installed on VistA Office EHR SemiViva 2.3.1) Sea Island Systems' modified VistALink routines

Setup Steps:

1. Install VistA Office EHR SemiViva 2.3.1
2. Verify VistALink 1.5 is already installed:
   GTM> D ^XUP <enter>
   Terminal Type set to: C-VT100 <enter>

3. Save original ^XOB* routines (See ReadMe.txt from Sea Island Systems', see references below)
   GTM> D ^%RO <enter>
   Routine: ^XOB* <enter>
   Routine: <enter>
   Output device: <terminal>: /tmp/xob_orig.ro <enter>
   Header Label: <enter>
   String comments <No>?: <enter>
4. Restore modified routines from xobv-gtm.ro (download from Sea Island Systems', see references below)
   GTM> D ^%RI <enter>
   Formfeed delimited <No>? <enter>
   Input device: <terminal>: /tmp/xobv-gtm.ro <enter>
   Output directory: <VistAOfficeEHR>/gtm_V5.2-000/r/ <enter>     <-- don't forget the last slash
5. Verify modified routines installed
   GTM> ZLINK "XOBVTCPL" WRITE $TEXT(+5^XOBVTCPL) <enter>
Output should be:
; SIS/LM - Modified for GT.M - Mar 23, 2004

6. Start the listener
   GTM> JOB LISTENER^XOBVTCPL(8001) <enter>

7. Verify listener has started
   GTM> <Press CTRL-Z>
   $ lke show all <enter>
Output should be:

DEFAULT
       ^%ZIS(8994.171,RPCB Listener,ROU,VAH,ROU:KLW133,9210)
                        Owned by PID= 32102 which is an existing process
       ^XOB(18.01,VistALink Listener,ROU,VAH,ROU:KLW133,8001)
                        Owned by PID= 18338 which is an existing process
$ fg

8. Telnet test to listener
   telnet localhost 8001
   you should connect if the listener is up

9. Create a user (or use existing user)
   User's Access/Verify Code must use capital letters

10. Grant Kernel Access to Sample Application 
    In User Edit, for Primary/Secondary Menu Options, assign “XOBV VISTALINK TESTER”

11. Installing VistALink sample application files
    unzip XOB_1_5.ZIP
    cd vlj-1.5.0.026/samples/J2SE

copy VistALink libraries (under vlj-1.5.0.026/jars dir)
vljConnector-1.5.0.026.jar
vljFoundationsLib-1.5.0.026.jar
vljSecurity-1.5.0.026.jar

copy supporting library files
j2ee.jar (get from J2EE SDK)
jaxen-dom.jar (under vlj-1.5.0.026/rar/ExplodedVistaLinkRAR/lib dir)
jaxen-core.jar 
saxpath.jar 
log4j-1.2.8.jar

create setVistaLinkEnvironment.sh from setVistaLinkEnvironment.bat
create runSwingTester.sh from runSwingTester.bat

Running SwingTester sample application

source setVistaLinkEnvironment.sh
. ./setVistaLinkEnvironment.sh

launch SwingTester
