java ee - Are EJBs applications like Web Services? -

-

is developping ejb application considered web services ?

or 2 different ?

or can make ejbs web services ?

my answer yes , no.

no in sense ejb programming model. programming model contains concepts such security, transaction demarcation, state management , persistency (stateful or stateless beans), , more. while web service more remoting technology, is, way connect systems, soap in case of web service. under perspective both different topic (web service compared rmi-iiop though).

yes in sense both referred technologies expose service outside (as long it's stateless). under perspective belong same category. , ejb can indeed exposed web service annotating bean accordingly.

hope brings light distinction.

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...
