java - IJ000305: Connection error occured -

-

i'm getting 2 exceptions when calling stored proc mdb.

the first 1 shows nullpointerexception. second 1 talks lock owned during cleanup.

i enabled tracing on org.jboss.jca, , seems connections fine. connection obtained(5b0032a7) not in use, , there no other connection requests before errors happen.

to rule out multi-threading, updated code send 1 message mdb. there no other threads using connections.

the whole thing runs locally on desktop.

there mdb makes calls same datasource(all work fine), , once it's done (i verified it's done , connections closed), sends 1 message mdb errors below show up.

why happening?

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
