java - Servlet 2.5 injection of EJB3.0, all packaged as WAR -

-

i'm trying achieve goal: deploy war made of simple servlet injection of ejb, , invoke business method on it.

all made using maven project made 2 components:

1) sample ejb (pom.xml packaged ejb) 2) sample war (servlet, pom.xml packaged war. dependency ejb module)

i tell first i'm able exercise in way, packaging both war , ejb inside ear, not above mentioned one. can tell me if there limitation of used application server (weblogic 10.3.3)?

code snippet simpleservlet (war):

public class simpleservlet extends httpservlet {  @ejb(mappedname="ejb/simplesessionbean") private simplesessionremote simplesessionbean;

code snippet simplesession remote interface (ejb):

@remote public interface simplesessionremote {     string getmessage(); }

code snippet simplesession bean class (ejb):

@stateless(name="simplesessionejb", mappedname="ejb/simplesessionbean") @remote(simplesessionremote.class)  public class simplesession { ...

the ejb doesn't have weblogic-ejb-jar.xml deployment descriptor, annotated ejb.

after deploy of war in admin console, null reference after direct injection in servlet.

what's wrong? did forget step?

=================================

update: found answer myself

it not possible app server not supporting ejb 3.1

indeed weblogic i'm using supports ejb 3.0 stated here:

http://docs.oracle.com/cd/e14571_01/web.1111/e14529/compatibility.htm

"

weblogic server 11g release 1 (10.3.3) jee5 compatible

"

java ee 5 supports ejb 3.0 stated here:

http://download.oracle.com/otn-pub/jcp/javaee-5.0-fr-eval-oth-jspec/javaee-5_0-fr-spec.pdf?authparam=1377598866_1774a69dcb8b920f69c0c2623068e247

i have checked in ejb 3.0 specifications (jsr220), where, actually, never explicity mentioned not possible package ejb inside .war. fact not supported, believe, left implied.

to provide complete overview have checked ejb 3.1 specifications (jsr318) explicity stated "

enterprise beans can packaged within web application module (.war)"

, chapter 20 packaging.

so can conclude scope of exercise demonstrate packaging of enterprise bean in war not possible application server doesn't support ejb 3.1 specifications.

kind regards, pierluigi salera

servlet 2.5 implies java ee 5. ejb in war supported since java ee 6.

you've 2 options:

  1. upgrade java ee 6 compatible container.
  2. stick java ee 5 , create ear instead of war. ear can consist of ejb jar , war.

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...

this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
