Reindexing custom class - [DynamicQueryFactoryImpl:96] Unable find model

[Jan Tošovský, geändert vor 9 Jahren.]

Dear All,

I've created two custom entities using a service builder. It is similar to WIKI node with multiple pages.

In the custom indexer there is overridden internal class WebHelpPageActionableDynamicQuery() which is executed during (re)indexing:

protected void reindexPages(long companyId, long groupId, final long documentId) throws PortalException, SystemException {

        LOGGER.info("Reindex pages: " + documentId);

        ActionableDynamicQuery actionableDynamicQuery = new WebHelpPageActionableDynamicQuery() {

            @Override
            protected void addCriteria(DynamicQuery dynamicQuery) {

                LOGGER.info("Adding a criteria: " + documentId);
                Property documentIdProperty = PropertyFactoryUtil.forName("documentId");
                dynamicQuery.add(documentIdProperty.eq(documentId));
            }

            @Override
            protected void performAction(Object object) throws PortalException {

                WebHelpPage page = (WebHelpPage) object;
                if (page != null) {
                    LOGGER.info("pageTitle" + page.getTitle());
                }
                addDocument(getDocument(page));
            }
        };

        actionableDynamicQuery.setCompanyId(companyId);
        actionableDynamicQuery.setGroupId(groupId);
        actionableDynamicQuery.setSearchEngineId(getSearchEngineId());

        actionableDynamicQuery.performActions();
    }

My plugin is deployed outside the ROOT context and it is most likely the reason of the following error:

15:04:07,056 ERROR [http-bio-8080-exec-2][DynamicQueryFactoryImpl:96] Unable find model com.liferay.portlet.webhelp.model.impl.WebHelpPageImpl

But it is not clear to me how this kind of indexing is supposed to work. When actionableDynamicQuery.performActions() method (from my portlet) is executed, it calls BaseActionableDynamicQuery which is 'somehow' working again with my classes which are unknown to it.

Is there any example portlet utilizing indexing? My code is based on WIKI portlet where this context mixture is not the case. How can I deal with it properly?

The most strange thing is requirement of my custom Impl class by DynamicQueryFactoryUtil. It is not part of my custom service (which is located in lib/ext folder), hence unreachable by the specified class loader in WebHelpPageActionableDynamicQuery class:

com.liferay.portlet.webhelp.service.ClpSerializer.class.getClassLoader()

In this particular case I'll try to use portal classloader instead, but I'd rather avoid those Impl calls if possible. Can I influence this?

Exactly same symptoms are reported in https://issues.liferay.com/browse/LPS-46100.

I've found a workaround using the following code:

ClassLoader classLoader = (ClassLoader) PortletBeanLocatorUtil.locate(ClpSerializer.getServletContextName(), "portletClassLoader");
actionableDynamicQuery.setClassLoader(classLoader);

It prefers portlet classLoader over default one.

Below code will resolve DynamicQueryFactoryImpl:100] Unable find model

ClassLoader cl = Reciprocal.class.getClassLoader();
DynamicQuery dynamicQuery = DynamicQueryFactoryUtil.forClass(Reciprocal.class, cl);
Projection projection = ProjectionFactoryUtil.distinct(ProjectionFactoryUtil.property("state"));
dynamicQuery.add(PropertyFactoryUtil.forName("country").eq("Malaysia"));

dynamicQuery.setProjection(projection);
List<Object> stateList = ReciprocalLocalServiceUtil.dynamicQuery(dynamicQuery);
