Hi Gang,
Can you please advise on below:
i need to get assets by tags.
Using this code:
String tagName = "news";
long scoprGroupId = 4544986;
System.out.println("scoprGroupId:>>>>"+scoprGroupId);
AssetTag assetTagObj = AssetTagLocalServiceUtil.getTag(scoprGroupId, tagName);
long tagid = assetTagObj.getTagId();
System.out.println("tagid:"+tagid);
AssetEntryQuery assetEntryQuery = new AssetEntryQuery();
long[] anyTagIds = {tagid};
for(int i = 0; i < anyTagIds.length;i++)
{
System.out.println("[] anyTagIds:"+anyTagIds);
}
assetEntryQuery.setAnyTagIds(anyTagIds);
List assetEntryList = AssetEntryLocalServiceUtil.getEntries(assetEntryQuery);
AssetRendererFactory assetRendererFactory = AssetRendererFactoryRegistryUtil.getAssetRendererFactoryByClassName("com.liferay.portlet.journal.model.JournalArticle");
AssetRenderer assetRenderer = null;
String path="";
System.out.println("outside for loop>>>>>>");
for(int i=0; i < assetEntryList.size(); i++)
{
System.out.println("inside for loop<<<<<<<<<<");
AssetEntry aAssetEntry = (AssetEntry)assetEntryList.get(i);
System.out.println("AssetEntry aAssetEntry = (AssetEntry)assetEntryList.get(i)");
JournalArticleResource journalArticleResourceObj = JournalArticleResourceLocalServiceUtil.getJournalArticleResource(aAssetEntry.getClassPK());
System.out.println("JournalArticleResource journalArticleResourceObj");
JournalArticle journalArticleObj = JournalArticleLocalServiceUtil.getArticle(scoprGroupId,journalArticleResourceObj.getArticleId());
System.out.println("JournalArticle journalArticleObj");
JournalArticleDisplay articleDisplay = null;
System.out.println("JournalArticleDisplay articleDisplay = null");
assetRenderer = assetRendererFactory.getAssetRenderer(aAssetEntry.getClassPK());
System.out.println("assetRenderer =");
path = assetRenderer.render(request, response, AssetRenderer.TEMPLATE_FULL_CONTENT);
System.out.println("path:"+path);
request.setAttribute("ASSET_RENDERER_FACTORY", assetRendererFactory);
System.out.println("assetRendererFactory");
request.setAttribute("ASSET_RENDERER", assetRenderer);
System.out.println("assetRenderer");
String articleId=aAssetEntry.getClassPK()+"";
System.out.println("articleId:"+articleId);
}
But getting error at Red marked line.
Error from log:
