Thanks for the reply
I probably did something wrong because now it's working.
There is mistake in
OObjectDatabaseTx db = OObjectDatabasePool.global().acquire(
"local:c:/tmp/odb", "admin","admin");
and shold be only 'dbPool' instead 'OObjectDatabaseTx db'.
Anyway, there is warning when deploying:
WARNING: Sun Unsafe direct memory implementation is going to be used,
this implementation isnot stable so please use JNA version instead.
And an error when undeploying:
SEVERE: The web application [/OrientDB_WebTest] created a ThreadLocal with
key
of type[com.orientechnologies.orient.core.db.OScenarioThreadLocal] (value [
com.orientechnologies.orient.core.db.OScenarioThreadLocal@186807a8]) and a
value of type [com.orientechnologies.orient.core.db.OScenarioThreadLocal.
RUN_MODE] (value [DEFAULT]) but failed to remove it when the web
application was stopped. Threads are going to be renewed over time to try
and avoid a probable memory leak.
I know close() method only release it to the owner pool, but what's the
proper way to close all pool?
Also I have an error when I'm trying to open "remote:localhost/tmp/odb"
similar way like in OreintDB documentation.
SEVERE: Startup of context /OrientDB_WebTest failed due to previous errors
SEVERE: Exception during cleanup after start failed
org.apache.catalina.LifecycleException: Manager has not yet been started
at org.apache.catalina.session.StandardManager.stop(StandardManager.
java:934) ...
What's the correct way for access to the database?
Should I use ServletContextListener just for register all entity classes
and then open the database in EJB or servlet each time I need access to
database?
OObjectDatabaseTx db = OObjectDatabasePool.global().acquire(
"plocal:c:/tmp/odb", "admin","admin");
...
db.close();
Cheers,
Tomek
