    <p>My requirement was to develop an application to read data from user_ table which is one of the default table present in liferay default database lportal and publish that data in pdf format. Each and every thing is working fine but when I was try to increase the size of pages then except first page all other pages size increases according to my need. I don't know why this is happening and why only first page size is not increases. my action class code is</p> <pre><code> public class pdfPortlet extends MVCPortlet { public void serveResource(ResourceRequest req, ResourceResponse res) throws PortletException, IOException { if(req.isUserInRole("administrator")) { try { adminMethod(req,res); } catch (PortalException e) { e.printStackTrace(); } catch (SystemException e) { e.printStackTrace(); } catch (DocumentException e) { e.printStackTrace(); } } else { userMethod(req,res); } } /********** adminMethod which can fetch the whole user data from user_ table * @throws SystemException * @throws PortalException * @throws DocumentException * @throws IOException **********/ public void adminMethod(ResourceRequest req, ResourceResponse res) throws PortalException, SystemException, DocumentException, IOException { int numOfUser=UserLocalServiceUtil.getUsersCount(); //get the number of users String remoteUserId = req.getRemoteUser(); //getting current user id Integer io=Integer.parseInt(remoteUserId); //getting current userid int currentUserId=io.intValue(); //typecasting from Integer to primitive int User tblUser = UserLocalServiceUtil.getUser(currentUserId);

    1. COThe wall of code and the context (database etc) add very little to the question and answer. It can be reduced to the relevant part: creating the document and pdfwriter, opening the document and setting the page size. In the answer the last 2 just need to be switched. Or you can define the page size in the constructor: `Document document = new Document(new Rectangle(2000, 2600));`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
