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

<@liferay_ui["asset-categories-summary"]
   className=entry.getClassName()
                    classPK=entry.getClassPK()
/>

Hi,
This is working in asset publisher and webcontents opened in asset publisher portlet.
How can we achieve this is web content display portet.

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.

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

Instead I have to do this ...

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

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.
