eclipselink - JPA: several relations -

-

i have trouble jpa , right annotations , tried lot of annotations , combinations @joincolumn, mappedby , on, still errors. use eclipselink (jpa 2.1).

i have owner class store:

@entity public class store extends baseentity {      @notnull     private string name;      @notnull     @onetomany     private list<price> listprices;      @notnull     @onetomany     private list<businesshours> listbusinesshours;      @notnull     @onetoone     @joincolumn(name="store_id")     private pointcoordinates pointcoordinates; ... }

this class pointcoordinates:

@entity public class pointcoordinates extends baseentity {      @notnull     private float long;      @notnull     private float lat;      @onetoone(mappedby="pointcoordinates")     private store store;     ... }

and 1 of "@onetomany" classes of 'store':

@entity public class businesshours extends baseentity {      private boolean holiday;      @manytoone     private store store;     ... }

i thought should work, because 'store' owner of 'pointcoordinates' have annotate attribute private store store @onetoone(mappedby="pointcoordinates") , on other side have annotate attribute private pointcoordinates pointcoordinates @joincolumn(name="store_id") still same error:

i have answer! got error because annotated pointcoordinates "@notnull". wrong, should use attribute "optional".

the reason other error got "local transaction has 1 non-xa resource: cannot add more resources" happened because had several different transactions several persistence units.

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
