JavaStoredProcUtils.loadStoredProcedureClass()
I'm not initiated to OSGi and eclipse development so i cannot use this
util method in a test environment, but googling for it i found this
awesomely readable source code that completeley gave me a clear vision:
env.put("java.naming.provider.url","ldap://localhost:"; + ldapServer.getPort()
+"/ou=system" );
....
<#142> Attributes spContainer =*new*
BasicAttributes("objectClass","top",*true* );
<#143> spContainer.get("objectClass" ).add("organizationalUnit" );
<#144> spContainer.put("ou","Stored Procedures" );
...
spCtx = ( LdapContext ) ctx.createSubcontext("ou=Stored Procedures",
spContainer
.....
/**
087 * Loads a Java class's stream data as a subcontext of an
LdapContext given.
088 *
089 * @param ctx
090 * The parent context of the Java class entry to be
loaded.
091 * @param clazz
092 * Class to be loaded.
093 * @throws NamingException
094 * If an error occurs during creating the subcontext.
095 */
096 public static void loadStoredProcedureClass( LdapContext ctx,
Class<?> clazz ) throws NamingException
097 {
098 byte[] buf = getClassFileAsStream( clazz );
099 String fullClassName = clazz.getName();
100
101 Attributes attributes = new BasicAttributes(
SchemaConstants.OBJECT_CLASS_AT, SchemaConstants.TOP_OC, true );
102 attributes.get( SchemaConstants.OBJECT_CLASS_AT ).add(
"storedProcUnit" );
103 attributes.get( SchemaConstants.OBJECT_CLASS_AT ).add(
"javaStoredProcUnit" );
104 attributes.put( "storedProcLangId", "Java" );
105 attributes.put( "storedProcUnitName", fullClassName );
106 attributes.put( "javaByteCode", buf );
107
108 ctx.createSubcontext( "storedProcUnitName=" + fullClassName ,
attributes );
109 }
so now i've clear how and where create the LDAP stored procedure
entries, thanks really a lot.
i just hope that i will able to compile the stored procedure class
outside the eclipse project, i'm tring with netbeans with the apacheds
jars added as a java class library.
i will let you know.
Thanks really a lot you saved me a lot of time!
Congraturations for the awesome ApacheDS project! i think it will matter
in the LDAP servers market (not only the opensource one).
Best regards,
Stefano.

Thank you for the interesting paper,
But i still can't understand how to pratically define a trigger....
e.g after putting
"AFTER Delete
CALL "com.example.ldap.util.sp.BackupTools:backupDeletedUserEntry"
( $deletedEntry );"
where do i need put the compiled
"com.example.ldap.util.sp.BackupTools" java class?
There is an utility method that you can use to inject the class into
the server :
JavaStoredProcUtils.loadStoredProcedureClass()
i understood (maybe) that i need to put the bytecode of the compiled
class somewhere in an LDAP enty, in a byte attribute... but where in
the tree? is there a particular apacheds system subtree where i can
put this kind of entries? is there some hello world example with
source class and final LDIF?
The best would be to follow the test class I mentionned in my previous
mail, if you step through it you'll see that the trigger is associated
with a subentry and an administrative point.
Sorry if I cant get any further at this moment, I'm not the one who
wrote this portion of the code, but as we need to review it and
improve the documentation in the next couple of months (ie, before
2.0), be sure that there will be some improvement soon.
