java - EclipseLink Canonical Metamodel from already compiled entity classes -


i cannot seem figure out how should eclipselink's canonicalmodelprocessor generate metadata classes entities mapped in orm.xml file, , not source files in current compilation unit, instead included in compiler's classpath.

i'm trying maven, calling compiler plugin without further options. verify eclipselink annotation processor executes, , finds both persistence.xml , orm.xml, , succeeds in processing both files. fails when internally walks through "roundelement" classes , tries map against defined in persistence unit. obviously, classes classpath not in "roundelements" list, , no code generated them, though metadata present , valid in internal persistenceunit object.

does have idea how work? thanks!

edit: excerpt of pom.xml:

<dependencies>   <dependency>       <groupid>com.model</groupid>     <artifactid>app-model</artifactid>       <version>1.0.0</version>   </dependency>   <dependency>       <groupid>org.eclipse.persistence</groupid>       <artifactid>eclipselink</artifactid>       <version>2.5.2</version>   </dependency>   <dependency>     <groupid>org.eclipse.persistence</groupid>     <artifactid>org.eclipse.persistence.jpa.modelgen.processor</artifactid>       <version>2.5.2</version>   </dependency>    <build>     <plugins>           <plugin>             <artifactid>maven-compiler-plugin</artifactid>           </plugin>       </plugins>     </build>

excerpt orm.xml:

... <entity class="com.model.app.appclass">     .... appclass defined in app-model artifact </entity>

ok - looking @ source code of eclipselink annotation processor, seems "not possible". ap walks source elements encountered compiler , matches them against has been loaded jpa metamodel - not other way round. now, created myself patched version of eclipselink annotation processor additionally walks entities, embeddables , mapped superclasses defined in xml , matches them against binary elements compile-time classpath. way, full metamodel can generated.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
