JAAS: Make application use Tomcat authentication settings -


is possible make web application uses jaas authenticate via tomcats default authentication method.

to illustrate: tomcat uses tomcat_users.xml authentications. web application has defined own method in jaas.cfg. how configure jaas.cfg in such way uses tomcat's method in when configuration in tomcat changes application's authentication method switches aswell.

current config looks this:

bonitaauth {    org.ow2.bonita.identity.auth.bonitaidentityloginmodule required;  };    bonitastore {    org.ow2.bonita.identity.auth.localstorageloginmodule required;  };    bonitaauth-default {    org.ow2.bonita.identity.auth.bonitaidentityloginmodule required domain="default";    org.ow2.bonita.identity.auth.localstorageloginmodule required domain="default";  };    bonitastore-default {    org.ow2.bonita.identity.auth.localstorageloginmodule required domain="default";  };    /**   * used rest server   */  bonitarestserver {    org.ow2.bonita.identity.auth.bonitarestserverloginmodule required logins="restuser" passwords="restbpm" roles="restuser";  };

the tomcat user repository defined tomcat realms. tomcat_users.xml file used memoryrealm. use jaas configuration (jaas.cfg) configure jaasrealm: http://tomcat.apache.org/tomcat-7.0-doc/realm-howto.html#jaasrealm

it possible use java ee authentication , implement own realm. have 3 options:

  1. implement tomcat realm interface http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/realm.html
  2. extend realmbase http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/realm/realmbase.html)
  3. extend jaasrealm http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/realm/jaasrealm.html

configure own realm in server.xml 

<realm classname="org.myrealm"/>

tomcat call authenticate method http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/realm/realmbase.html#authenticate%28java.lang.string,%20java.lang.string%29

in method can call jaas authentication.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

java - Are there any classes that implement javax.persistence.Parameter<T>? -

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
