Creator Tip: Displaying two dimensional array in the table component

This tip explains how to display a two dimensional array of data in the Table Component. Creator comes bundled with dataproviders to display database table in the Table, along with other dataproviders like ObjectArrayDataProvider and ObjectListDataProvider to display data from POJOs (Plain Old Java Objects) using reflection. Unfortunately no dataprovider exists to display just a two dimensional array of data.

Hi Winston, I have retry your tutorial with netbean 5.5 and Tomcat 5.5.17 on Linux and Windows. All works fine within netbean, so the table shows the values from MyArrayDataProvider after binding. But during execution on Jboss + Tomcat, the table shows instead of values a few msg "no items found".

Hi! My problem is same: It works fine within Netbean. When I execution on Java System App. Server, the first row in the table shows "no items found".

you guys should initiate the myArrayDataProvider with the following code: myArrayDataProvider = new MyArrayDataProvider(); then it will have the data in run time. but it sounds to me that the number of collums is fixed to 3 in the jar file so that it will not show all data (collumn 4) of the following 2D array: String[][] data = { {"a1","a2","a3","x1"}, {"a4","a5","a6","x2"}, {"a7","a8","a9","x3"}, {"a10","a11","a12","x4"}, {"a13","a14","a15","x5"} };

how do i convert the following code to populate / prerender a table component which is already draged and dropped into the page: (it worked very well in a normal servlet) out.println("No of matches="+hits.length()); out.println("<table><tr><th>Document</th><th>Score</th></tr>"); for (int i = 0; i < hits.length(); i++) { out.println("<tr><td>" + url + "</td><td>" + hits.score(i)+"</td></tr>"); } out.println("</table>");

Hi Winston, This question may be slightly off-topic, but I beg your patience. I am dynamically creating a Table backed by an ObjectListDataProvider. The objectType of the provider is a bean object which contains a Vector of values. What I am trying to do is bind a column's value to the value of each element of the Vector. When I use the following binding, "#{currentRow.value['resultList']}" (where resultList is my Vector), the entire contents of the vector appear in the table cell; however, if I use the following binding to access the first element in the vector: "#{currentRow.value['resultList.0']}", I get the following exception: Exception Details: org.apache.jasper.JasperException java.lang.IllegalArgumentException: resultList.0 Is my syntax wrong? or is this type of binding just not supported? I am using NetBean 5.5.1 w/VWP installed. Any help would be greatly appreciated.

i am trying to extend this data provider with the functionality to update the contents. so i've been looking at ObjectListDataProvider but i still didn't manage to make it work. how do i get the class to actually update stuff after the form has been submitted?
