Hi Sasmita,

Have you created custom table using service builder implementation in Liferay?

If yes, then you can create method in LocalServiceImpl file with custom logic to get records by articleId field from your custom table.

Does that table available in same DB ?
if yes, then you can create dummy service (using service builder) with the same entity name which you created in DB.
So you will get some auto generated finder methods and you can also write your finder to get data from DB table.
And then fetch one by one article id from custom table and use JournalArticleLocalServiceUtil class to fetch the content as per article id.

Hi Sasmita,

(1). If you wanted to fetch records from your custom table based on articleId field then:
First of all you need to add below finder tag in your service builder xml file and run build-service command.

<finder name="ArticleId" return-type="Collection">
<finder-column name="articleId" />
</finder>

Once you done with build-service command you can able to see finder method for articleId field in entity's persistence java file. Now next step is to create get/fetch method, for that you can open LocalServiceImpl java file and add the function which you have added in your attachment and don't forget to run build-service command after that. This is mandatory so that you can access this method from LocalServiceUtil object.

(2). If you wanted to fetch content from journal table based on articleId which is stored in your custom table then:

You can simply call "JournalArticleLocalServiceUtil.getArticle(<<articleId>>);" method and you will get JournalArticle object from this method. Hence you will get any content which you wanted to fetch from journal table based on articleId.

Best Regards,
Chirag Patadia.
