File Explorer in Java

Suite and Optimus Suite 5
#1

Hi,



I am trying to use file explorer in my java struts app. I am using dynamic tree loading concept.



First of all my tree works in IE but not FF it says " XML or text declaration not start of entity" here is the jsp that I am calling



<%@ page import=“com.beans.CreateFolderTree”%>

<%response.setContentType(“text/xml”);

out.println(“<?xml version=\"1.0\" encoding=\"UTF-8\"?>”);

CreateFolderTree navFol = null;

navFol = new CreateFolderTree();

System.out.println(“Inside JSP: “);

String strTree2 = navFol.getTree();

System.out.println(“strTree2: “+strTree2);

out.println(strTree2);

%>



whats wrong in this?





2. In dynamic tree loading when u click on the node u need to send the ID of node in URL inorder to create XML for the node



how do I get the node ID to send it in the URL for serXMLAutoLoading



tree=myLayout.cells(“a”).attachTree(“0”);

        tree.setImagePath(“dhtmlx/dhtmlxTree/codebase/imgs/”);

        tree.loadXML(”…/test/test_tree.jsp”);

        tree.setXMLAutoLoading(”…/test/test_tree.jsp?id=”);

        var sID = tree.getSelectedItemId();

        alert("Selected Node: " + sID);

        alert("This node has children: "+tree.hasChildren(sID));



Thanks

In case of FF the problem may occur because of any whitespace before <?xml declaraton (the declaration must be the first text in the output).

You can use onXLE event:


tree.attachEvent(“onXLE”,function(tree,itemId){


…


})

I was able to fix the problem I had with FF.



But the second Issue regarding dynamic loading of tree menu how do I get the ID of the node that is clicked to send it in the URL used for tree.setXMLAutoLoading(url)



Ex: I have to call this URL in which I ahve to send the ID as query Parameter  “/web/XMLTree.do?ID=”



 



 

#4


The id is sent automatically (the parameter name is id).


Please, read the article dhtmlx.com/docs/products/dhtmlxT … ml#dyntree

#5


So Can I just do request.getParameter(“id”) in my server side program?



and set tree.setXMLAutoLoading("/web/XMLTree.do")



 

#6

Yes, you can.

#7


I tried that. I am not getting ID in my server side program  :



ID from Tree: undefined



Here is what I has in my HTML



tree=myLayout.cells(“a”).attachTree(“0”);



tree.setImagePath("/dhtmlx/dhtmlxTree/codebase/imgs/");



tree.setXMLAutoLoading("/web/XMLTree.do");



tree.loadXML("/web/XMLTree.do?id=0");



tree.attachEvent(“onSelect”,showDirContent);



Here is what I had in my action class



 



public class XMLGrid extends Action {


public ActionForward execute(ActionMapping mapping, ActionForm form,



HttpServletRequest request, HttpServletResponse response)



throws Exception {




try{



System.out.println("ID from Tree: ");



String id = request.getParameter(“id”);



System.out.println("ID from Tree: "+ id);



PrintWriter out = response.getWriter();


response.setContentType(“text/xml; charset=iso-8859-1”);



response.setHeader(“Cache-Control”, “no-store, max-age=0, no-cache, must-revalidate”);



response.addHeader(“Cache-Control”, “post-check=0, pre-check=0”);



response.setHeader(“Pragma”, “no-cache”);



out.println("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");



CreateFolderTree navFol = null;



navFol = new CreateFolderTree(“netlib”, “dmadmin”,“180washington”, “/” + “NSS”);



System.out.println("Inside JSP: ");



String strTree2 = navFol.getTree();



System.out.println("strTree2: "+strTree2);



out.println(strTree2);


out.close();


return null;


} catch (Exception e){



return null;



}



}



}

This is my Intial XML



<?xml version=\"1.0\" encoding=\"UTF-8\"?>



























When I click on one of these Items I need the value spcified in the ID in the above XML in the server side program.

#9

I got it in My XML I had id specified in uppercase ID="" thats y it didn’t get the value.

#10


The correct root xml is:


<?xml version="1.0" encoding="UTF-8"?>

<item text=“DocResources” id="/NSS/DocResources" im0=“folderClosed.gif” child=“1”/>

<item text=“Exec” id="/NSS/Exec" im0=“folderClosed.gif” child=“1”/>

<item text="_ApplicationsOps-Eng" id="/NSS/_ApplicationsOps-Eng" im0=“folderClosed.gif” child=“1”/>

<item text="_ApplicationsRF-Perf" id="/NSS/_ApplicationsRF-Perf" im0=“folderClosed.gif” child=“1”/>




Please, check case of teh id attribute
