Hi,
does anyone know how to write codes on multiple query in the servlets.
that is when the user key more than 1 sql queries, the servlet will need to execute all the queries and display a result.
eg. a user enter the following:
select * from company;
select companyid,companyname from company;

does anyone know how to write codes on prepared statement in the servlet.
eg. when user enter select * from company where companyname=::name and address=::address;
it will need to prompt out something for the user to enter for the 2 input fields.
Thanx in advance

Hi Lasse Koskela,
i know that the taglib can only be in jsp file. In this program, i write the tree structure into a jsp file called myfile.jsp. The servlet will run the program and write it into myfile.jsp, after writing it to the myfile.jsp, the servlet will call myfile.jsp to display the tree. the program does work but there is one problem, that is how do i noe whether the user has click which nodes??

Hi
The program is what im currently doing. I write the program into a jsp file then i redirect it to the jsp file to display. Can anybody tell me how do i noe whether the user has click which node, and i need to display things that are related to the nodes that the user has juz click??
fos = new FileOutputStream("C:\\Tomcat 4.1\\webapps\\SDC1\\myfile.jsp");
// Connect print stream to the output stream
p = new PrintStream(fos);

p.println("<html>");
p.println("<head>");
p.println("<title>Files</title>");
p.println("</head>");

p.println("<body bgcolor=\"#ECDFCE\" link=\"blue\" vlink=\"purple\" alink=\"red\" style=\"scrollbar-face-color:#F5DEB3; scrollbar-arrow-color:indianred; scrollbar-track-color : papayawhip; scrollbar-shadow-color:black; scrollbar-highlight-color:''; scrollbar-3dlight-color:#BC7E41; scrollbar-darkshadow-Color:maroon;\" >");
p.println("<table width=\"100%\">");
p.println("<tr>");
p.println("<td width=\"50%\">");

File parentNode = new File(dirName + "\\" + user);

if (parentNode.isDirectory())
{
File[] childNode = parentNode.listFiles();

String parentName = parentNode.getName();

p.println("<%@ taglib uri=\"taglib.tld\" prefix=\"tree\" %>");

p.println("<tree:createTree treePicture=\"images/folder_idle.gif\" nodePicture=\"images/item_doc.gif\" openPicture=\"images/folder_open.gif\" dhtml=\"true\">");
p.println("<tree:addNode code=\"<b>" + parentName + "</b>\">");

for (int i = 0; i < childNode.length; i++)
{
String fileInDir = childNode[i].getName();
addnode.setCode(fileInDir);
String node = addnode.getCode();

if (childNode[i].isDirectory())
{
expandFiles(childNode[i].getAbsoluteFile());
}
}

p.println("</tree:addNode>");
p.println("</tree:createTree>");
}

thanx in advance...
