ORA-29541: impossible de risoudre la classe SYSTEM.jsearch

Question

Hello,
I explain my trouble
I have created a class Java jsearch.class
1) first try (it works !)
jsearch.java
import java.util.Locale;
import java.util.Date;
import java.io.*;
import oracle.ifs.beans.DirectoryUser;
import oracle.ifs.beans.DocumentDefinition;
import oracle.ifs.beans.Document;
import oracle.ifs.beans.Selector;
import oracle.ifs.common.SortSpecification;
import oracle.ifs.beans.LibraryObject;
import oracle.ifs.beans.PublicObject;
import oracle.ifs.beans.Folder;
import oracle.ifs.beans.LibraryService;
import oracle.ifs.beans.LibrarySession;
import oracle.ifs.beans.PrimaryUserProfile;
import oracle.ifs.beans.PublicObject;
import oracle.ifs.common.CleartextCredential;
import oracle.ifs.common.ConnectOptions;
import oracle.ifs.common.AttributeValue;
import oracle.ifs.common.IfsException;
public class jsearch {
//public static String buildsearch (String filename) throws IfsException
public static String buildsearch (String filename)
     filename=filename+" de la fonction buildsearch";
     return filename;
public static String search (String filename)
//      try {
          filename=buildsearch(filename);
//catch(IfsException e) { };
return filename;
j'exicute cette classe dans mon environnement Oracle IFS
(system/manager)
sous SQLPLUS en utilisant le script suivant :
-- @jsearch.sql
set serveroutput on
set echo off
spool jsearch.log
call dbms_java.loadjava('-f -r -v c:\YTW\myclasses\jsearch.class');
CREATE OR REPLACE function fsearch (s1 in VARCHAR2) return VARCHAR2
AS LANGUAGE JAVA
NAME 'jsearch.search(java.lang.String) return string';
spool off
set echo on
exec dbms_output.put_line(fsearch('ceci provient'));
l'exicution de ce script donne :
SQLPLUS>@jsearch
Appel termini.
Fonction criie.
SQL> exec dbms_output.put_line(fsearch('ceci provient'));
ceci provient de la fonction buildsearch
Procidure PL/SQL terminie avec succhs.
SQL>
ok it works
2) second try (it doesn't work...)
search.java
import java.util.Locale;
import java.util.Date;
import java.io.*;
import oracle.ifs.beans.DirectoryUser;

import oracle.ifs.beans.PrimaryUserProfile;
import oracle.ifs.beans.PublicObject;
import oracle.ifs.common.CleartextCredential;
import oracle.ifs.common.ConnectOptions;
import oracle.ifs.common.AttributeValue;
import oracle.ifs.common.IfsException;
public class jsearch {
public static String buildsearch (String filename) throws IfsException
//public static String buildsearch (String filename)
     filename=filename+" de la fonction buildsearch";
     return filename;
public static String search (String filename)
     try {
          filename=buildsearch(filename);
catch(IfsException e) { };
return filename;

Why I don't understand !!!

Answer 1

ok :)
my class does import many others, it is in fact a bit of code that sends an email using javamail api, the two packages used are mail.jar and activation.jar which i 've downloaded from javasun.and i think my problem is in these classes, in fact i've compiled myclass with javac, after having included the two packages (mail and activation), and it generated no error.
i have used sql*plus to load these packages :
exec sys.dbms_java.loadjava('-v -r -grant PUBLIC -synonym /lib/jaf-1_0_2/activation.jar');
exec sys.dbms_java.loadjava('-v -r -grant PUBLIC -synonym /lib/javamail-1_3/mail.jar');
is there any problem in these commands? sql*plus said 'Procidure PL/SQL terminie avec succhs.' :))
if the jars are successfully loaded, where can i find them in oracle ? how can i verify they are really loaded in the database ?
thanks for help
