Hi,
I am developing Intranet site with OpenCms. I have a problem with createResource method. First JSP is :
<%
// Create a JSP action element
CmsJspActionElement cms = new CmsJspActionElement(pageContext, request, response);
// Create a string of requested file
String filename = cms.getRequestContext().getUri();
// Get CmsObject
CmsObject cmsObject =cms.getCmsObject();
String userName = request.getParameter("OPENCMSUSERNAME");
String password = request.getParameter("OPENCMSPASSWORD");
boolean logout = false;
if (request.getParameter("OPENCMSUSERNAME") == null) {
%>
<table>
<form name="login" method="post" action="<%= cms.link("ImportPDF.jsp")%>">
<tr align="left"><td colspan="2"><br><p><b>Prijava:</b></p></td></tr>
<tr>
<td><p>Username: </p></td>
<td><p><input type="text" name="OPENCMSUSERNAME" size="15" maxlength="64"></p></td>
</tr>
<tr>
<td><p>Password: </p></td>
<td><p><input type="password" size="15" maxlength="32" name="OPENCMSPASSWORD"></p></td>
</tr>
<tr align="center"><td colspan="2"><input type="submit" value="Prijava"></td></tr>
</form>
</table>
<%
} else {
out.println("Pocinjem prijavu na OpenCMS !!");
try {
cmsObject.loginUser(userName,password);
out.println("Welcome to OpenCMS! \n Korisnik: " + userName + "<br>");
%>
<form name="webhouse" action="<%= cms.link("/intranet/jsp/obrada1.jsp")%>" method="post" enctype="multipart/form-data">
Naslov:<INPUT size=80 name="NavText"><br>
Virtualni fajl sistem:<INPUT size=80 name="Path"><br>
Ključne reči:<BR>
<TEXTAREA name="Keywords" rows=3 cols=25 size="30"></TEXTAREA>
Opis strane:<BR>
<TEXTAREA name="Description" rows=3 cols=25></TEXTAREA><br>
<INPUT type=file size=60 name="Page"><br>
<INPUT type=radio value="V1" name="Format"> HTML
<INPUT type=radio value="V2" name="Format"> PDF<br>
<INPUT type=submit value=Pošalji name=Send> <INPUT type=reset value=Poništi name=Cancle>
</form>
<!-- enctype="multipart/form-data" -->
<%
//nastavak
} catch(CmsException e) {
System.out.println(new java.util.Date() + " OpenCMS INFO: Neuspesno ulogovan korisnik " + userName);
out.println("<h2>Neuspešna prijava na sistem, molimo pokušajte ponovo</h2>");
}//end catch
}
%>
As you can see it's very simple and I use it for log in and showing a form for uploading PDF files. After that I use another JSP for processing data. Code is:
<%
// Create a JSP action element
CmsJspActionElement cmsJsp = new CmsJspActionElement(pageContext, request, response);
// Create a string of requested file
String filename = cmsJsp.getRequestContext().getUri();
CmsObject cms = cmsJsp.getCmsObject();
String format = cmsJsp.getRequestContext().getRequest().getParameter("Format");
out.println("Format: " + format);
String pathVFS = "";
Enumeration files = cms.getRequestContext().getRequest().getFileNames();
out.println("Prosao enumeration!!");
while (files.hasMoreElements()) {
out.println("Usao u while!!");
String fileName = (String) files.nextElement();
fileName = fileName.toUpperCase();
System.out.println("Ime: " + fileName);
if (fileName.endsWith(".PDF") && fileName != "unknown") {
System.out.println("Usao i if (PDF)");
byte[] filecontent = (byte[]) cms.getRequestContext().getRequest().getFile(fileName);
//Prijava admin user-a
try {
cms.loginUser("Admin","opencms");
cms.getRequestContext().setCurrentProject(3);
System.out.println("Uspesno logovanje Admin-a");
Hashtable props = new Hashtable();
//props.put("Title",cmsJsp.getRequestContext().getRequest().getParameter("Page"));
props.put("Description",cmsJsp.getRequestContext().getRequest().getParameter("Description"));
props.put("Keywords",cmsJsp.getRequestContext().getRequest().getParameter("Keywords"));
props.put("NavText",cmsJsp.getRequestContext().getRequest().getParameter("NavText"));
System.out.println("Setovani Properties za file-ove");
CmsResource cmsres = null;
System.out.println("Kreiranje PDF file-a u CMS-u!!");
pathVFS = cms.getRequestContext().getRequest().getParameter("Path");
try{
//cms.lockResource(pathVFS);
cms.getRequestContext().setCurrentProject(3);//temp project ID
System.out.println("Na putanji: " + pathVFS);
cmsres = cms.createResource(pathVFS, fileName, "binary", props, filecontent);
System.out.println("PDF file je uspesno kreiran u CMS-u !!");
}catch(CmsException e){
System.out.println("Neuspesno kreiranje !!!");
out.println("Neuspesno kreiranje PDF!!!");
e.printStackTrace();
}
} catch(CmsException e){
System.out.println("Neuspesno logovanje !!!");
}
}
}
%>
VFS path is OK. I've got this error:
