THANK YOU!!!
Downloaded v1_ur1-b10 - both 'appclient only' and appclient/JWS run my
apps!!!
But, i am left with a few remnant problems that i would like to request some
assistance.
1)Run J2SE application, DrawingAddon.jar
command line: java -Dderby.system.home=/usr/local/dbHome -jar
/usr/local/provision/DrawingAddon/dist/DrawingAddon.jar
this runs beautifully - can save and retrieve SVG drawings from Derby. All
good here.
2)Run J2SE application, KART.jar
command line: java -Dderby.system.home=/usr/local/dbHome -jar
/usr/local/provision/KART/dist/KART.jar
The KART app starts up, an EntityManagerFactory is ready to do work. In the
KART app, the user clicks on "Visit Addon Store". The DrawingAddon.jar is
available (was deployed as a web app to Glassfish). When DrawingAddon is
selected, a URLClassLoader loads the app, DrawingAddon. The user can create
a new SVG drawing. But, when the user asks for a listing of the drawings in
the database, there are none. i have a sysOut in the addon classes that
reports that getProperty(derby.system.home) is /usr/local/dbHome - this is
correct.
The line that errors is "em = emf.createEntityManager()" where em has been
declared as "private Entitymanager em;"
i admit that this is not a Glassfish problem. i believe it is a class
loader / Derby problem - and i ain't got no clue how to fix it. A poke in
the right direction would be appreciated.
3) Run 'appclient only', KARTClient.jar
command line: /usr/local/glassfish/glassfish/bin/appclient -client
/usr/local/glassfish/glassfish/domains/domain1/generated/xml/j2ee-modules/KA
RT/KARTClient.jar
The KART app starts up, an EntityManagerFactory is ready to do work. In the
KART app, the user clicks on "Visit Addon Store". The DrawingAddon.jar is
available (was deployed as a web app to Glassfish). When DrawingAddon is
selected, a URLClassLoader loads the app, DrawingAddon. Then i get a brand
shiny new error - Internal Exception: java.sql.SQLException: No suitable
driverError Code:0 - followed by more stack trace.
The line that errors is "em = emf.createEntityManager()" where em has been
declared as "private Entitymanager em;"
i am not saying that this is an appclient problem. It is just interesting
how much different the error is from step 2 above.
4) Run appclient/JWS, KARTClient.jar
URL in browser:
http://gateway:8080/KART?prop=DBHome=/usr/local/dbHome
The KART app starts up, an EntityManagerFactory is ready to do work. In the
KART app, the user clicks on "Visit Addon Store". The DrawingAddon.jar is
available (was deployed as a web app to Glassfish). When DrawingAddon is
selected, a URLClassLoader loads the app, DrawingAddon. Then i get a good
old faithful error - java.securityAccessControlException - stack trace seems
to imply that Toplink is doing getProperty(derby.system.home).
Can you tell me which blog to read for instruction on setting the
SecurityManager for appclient/JWS?

Martin,
Can you try it on the latest promoted build?
