Problem with new type of Document and WebUI

Question

Hello everyone,
My problem is quite strange. Here it is :
I have created a new subclass of Document using the API, named IFSDocument. So, i created a class IFSDocumentDefinition and a class IFSDocument. Here is the code :
IFSDocumentDefinition :
package fr.sword.ifs.GestionDocument;
public class IFSDocumentDefinition extends DocumentDefinition {
protected LibrarySession ifsSession;
public IFSDocumentDefinition() throws IfsException {
setClassname("IFSDOCUMENT");
public IFSDocumentDefinition(LibrarySession ifsSession) throws IfsException {
this();
this.ifsSession = ifsSession;
IFSDocument :
package fr.sword.ifs.GestionDocument;
public class IFSDocument extends TieDocument{
public IFSDocument(LibrarySession session, Long id, Long classId, S_LibraryObjectData data) throws IfsException {
super(session, id, classId, data);
In this class, i've created a new ClassObject to handle my new type. Here is the method :
public void createIFSDocument(LibrarySession ifsSession) throws IfsException {
DocumentDefinition myDocDef = new DocumentDefinition(ifsSession);
Document doc = (Document)ifsSession.createPublicObject(myDocDef);
ClassObject co = doc.getClassObject();
ClassObjectDefinition cod = new ClassObjectDefinition(ifsSession);
cod.setSuperclass(co);
cod.setSuperclassName(co.getName());
cod.setName("IFSDocument");
ifsSession.setInstallationMode(true);
c = (ClassObject)ifsSession.createSchemaObject(cod);
c.setBeanClasspath("fr.sword.ifs.GestionDocument.IFSDocument");
c.setSelectorClasspath("fr.sword.ifs.GestionDocument.S_IFSDocumentSelector");
c.setServerClasspath("fr.sword.ifs.GestionDocument.S_IFSDocument");
ifsSession.setInstallationMode(false);
I also created two classes named S_IFSDocument and S_IFSDocumentSelector that do nothing special but calling super(). Here is the code :
S_IFSDocument :
package fr.sword.ifs.GestionDocument;
public class S_IFSDocument extends S_TieDocument {
public S_IFSDocument(S_LibrarySession session, java.lang.Long classId) throws IfsException {
super(session, classId);
public S_IFSDocument (S_LibrarySession session, S_LibraryObjectData data) throws IfsException {
super (session, data);
S_IFSDocumentSelector :
package fr.sword.ifs.GestionDocument;
public class S_IFSDocumentSelector extends S_DocumentSelector {
protected S_IFSDocumentSelector(S_LibrarySession session) {
super(session);
protected S_IFSDocumentSelector(S_LibrarySession session, Long classId) throws IfsException {
super(session, classId);
Everything seems to work since i'm able to create new objects of type IFSDocument. I can add custom attributes, put them into folders etc. BUT when i use the web interface, i have the following error message :
oracle.ifs.common.IfsException : IFS-21002: Unable to construct S_LibraryObject for class fr.sword.ifs.GestionDocuments.S_IFSDocument (invalid class path specification)
I don't understand why my classpath is invalid since i simply call super(). So, where is the problem ? Do i have to put the class(es) on the Server ?
By the way, what's the purpose of the Selector class ? Is it related to search ?
Thanks in advance.
Regards,
Guillaume
PS : i'm using iFS 1.1.9 on Oracle 8.1.7 and NT4 sp6

Hi Guillaume,
don't know exactly but what i have in mind
is that everything in iFS API that starts
with a S_ is executed at server side, so the
classes should exist there.
You can easily check this if you put your
classes in directory %IFS_HOME%\custom_classes
You are right, the Selector class is for SIMPLE searches, for example:
LibrarySession ifsSession;
String searchCriteria = PublicObject.NAME_ATTRIBUTE + " = '<someName>'";
Selector mySelector = new Selector(ifsSession, Document.CLASS_NAME, searchCriteria);
LibraryObject objs[] = mySelector.getItems();
