Answer 1

thanks
i added the missing jaxen.jar to classpath.
now the error disappeared but I'm not getting the right results.
i changed my code to this :
if (sugarSearchInfoArray == null)
                     SAXReader reader = new SAXReader();
                     Document document = reader.read(Utils.getResourceURL("/SugarSoap.ArchiveSettings.xml"));
                    ArrayList mlist = new ArrayList();
                    List list = document.selectNodes( "//Module" );
                    for (Iterator iter = list.iterator(); iter.hasNext(); ) {
                        Node node = (Node) iter.next();
                        String module = node.valueOf( "@name" );
                        String defName = module;
                        _logger.debug("module->"+defName);
                        String strIcon=node.valueOf( "@icon" );
                        int num2=Integer.parseInt(strIcon);
                        _logger.debug("icon num->"+num2);
                        List list3 = document.selectNodes(node.getUniquePath()+"/SearchFields/descendant::*" );
                        _logger.debug("list3->"+list3.size());
                        for (Iterator iter3 = list3.iterator(); iter3.hasNext(); ){
                             Node child = (Node) iter3.next();
                            String name = child.valueOf( "@name" );
                            _logger.debug("search field->"+name);
                            list3.add(name);
                        List list4 = document.selectNodes( node.getUniquePath()+ "/DisplayFields/descendant::*" );
                        for (Iterator iter4 = list4.iterator(); iter4.hasNext(); ){
                             Node child = (Node) iter4.next();
                            String name = child.valueOf( "@name" );
                            _logger.debug("display field->"+name);
                            list4.add(name);
                        SugarSearchInfo info = new SugarSearchInfo(module, null, num2, (String[]) list3.toArray(new String[list3.size()]), (String[]) list4.toArray(new String[list4.size()]));
                        mlist.add(info);
                    Module_list _list = this.soap.get_available_modules(this.sessionid);
                    if (_list.getError().getNumber().equals("0"))
                        boolean flag2 = false;
                        SugarSearchInfo[] sList=(SugarSearchInfo[])mlist.toArray(new SugarSearchInfo[mlist.size()]);
                        for (SugarSearchInfo info2 : sList)
                            for (String str5 : _list.getModules())
                                if (info2.module.equals(str5))
                                    flag2 = true;
                                    break;
                            if (!flag2)
                                list.remove(info2);
                    sugarSearchInfoArray = (SugarSearchInfo[]) mlist.toArray(new SugarSearchInfo[mlist.size()]);
                    }unfortunately I get this exception :
