How to fetch categories in web content display

I read this and I think why can't I do this ... ${article.categories} ???

Instead I have to do this ...

&lt;#assign articleId = &nbsp;.vars['reserved-article-id'].data /&gt;&nbsp;
&lt;#assign assetEntryLocalService = serviceLocator.findService("com.liferay.asset.kernel.service.AssetEntryLocalService") /&gt;&nbsp;
&lt;#assign journalArticleLocalService = serviceLocator.findService("com.liferay.journal.service.JournalArticleLocalService") /&gt;&nbsp;
&lt;#assign article = journalArticleLocalService.getArticle(getterUtil.getLong(scopeGroupId), articleId)&gt;&nbsp;
&lt;#assign asset = assetEntryLocalService.getEntry('com.liferay.journal.model.JournalArticle', article.resourcePrimKey) &gt;&nbsp;&lt;@liferay_asset["asset-categories-summary"] &nbsp; className='${asset.getClassName()}' classPK=article.resourcePrimKey /&gt;&nbsp;

WTH?? Time matters, I don't have two hours to spend researching, another 4 hours trying to get something working and then a week goes by and I haven't delivered or finished my template. For personal projects yes fine. But when someone in an enterprise needs something by the end of the day I'm sorry but Liferay truly sucks for delivering solutions quickly.

I fear, you have to use something like this: (works only after allowing the use of serviceLocator in system settings)

    journalArticleResourceLocalService = serviceLocator.findService("com.liferay.journal.service.JournalArticleResourceLocalService")
    assetEntryLocalService = serviceLocator.findService("com.liferay.asset.kernel.service.AssetEntryLocalService")

    journalArticleId = .vars['reserved-article-id'].data
    articleResourcePrimaryKey = journalArticleResourceLocalService.getArticleResourcePrimKey(themeDisplay.getScopeGroupId(), journalArticleId)
    assetEntry = assetEntryLocalService.getEntry("com.liferay.journal.model.JournalArticle", articleResourcePrimaryKey)
    assetCategories = assetEntry.getCategories()

I wished, the whole JournalArticle Object or at least some nice helper objects were available in the template.

In Webcontent Display you may need to get the asset of selected webcontent then fetch the categories, you may refer below code snippet (Liferay 7.1), You can also fetch the list of categories from asset object (asset.getCategories()) and use that

&lt;#assign articleId = &nbsp;.vars['reserved-article-id'].data /&gt;&nbsp;
&lt;#assign assetEntryLocalService = serviceLocator.findService("com.liferay.asset.kernel.service.AssetEntryLocalService") /&gt;&nbsp;
&lt;#assign journalArticleLocalService = serviceLocator.findService("com.liferay.journal.service.JournalArticleLocalService") /&gt;&nbsp;
&lt;#assign article = journalArticleLocalService.getArticle(getterUtil.getLong(scopeGroupId), articleId)&gt;&nbsp;
&lt;#assign asset = assetEntryLocalService.getEntry('com.liferay.journal.model.JournalArticle', article.resourcePrimKey) &gt;&nbsp;
&lt;@liferay_asset["asset-categories-summary"] &nbsp; className='${asset.getClassName()}' classPK=article.resourcePrimKey /&gt;&nbsp;

Hi,
You can try using taglib for showing asset Categories of selected asset in web content ftl

&lt;@liferay_ui["asset-categories-summary"]
&nbsp; &nbsp;className=entry.getClassName()
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;classPK=entry.getClassPK()
/&gt;
