How to add a new TLD file to your project in JDeveloper?

You want to use the new tag library you found on internet, in your project. You copy the JAR/TLD file in your project's WEB-INF/lib directory and make the necessary changes in your code, rebuild your code... and get error during build process!

If your error is: " is is not a registered TLD Namespace", chances are you forgot to register the TLD with JDeveloper. Here is how to do it.

Select your project root. Right click->Project Properties. By default Libraries will be selected, if not select it. See if your TLD/JAR is present in the list of libraries. If not click on 'Add Library' and select your libraries. These should now appear in the libraries list. Also make sure to select JSF also.

Refresh your project. The errors should be gone now. If you are getting any errors it is possible that you are missing any library required for your tag library to function properly. Check the documentation of your taglib to pinpoint and resolve such issues.

Your feedback is welcome.

File upload problem: UTF-8 encoding not honored when form has multipart/form-data

The problem that I was facing was something like this. I was using Apache Commons File Upload library to upload and download some file.

I had a form in which user can upload a file and another field 'name' in which she can give any name to the file being loaded.


When I submitted the form, the file was uploaded fine but the value in name field was garbled. I followed all the possible suggestions I found:

<%@page pageEncoding="UTF-8"%> set. <%@page contentType="text/html;charset=UTF-8"%gt; set after the first directive. <meta equiv="Content-Type" content="text/html;charset=UTF-8"> in the head. enctype="multipart/form-data" attribute in the form. accept-charset="UTF-8" attribute in the form.
in the Servlet:
before doing any operations on request object: request.setCharacterEncoding("UTF-8"); For accessing the value

FileItem item = (FileItem) iter.next();

if (item.isFormField()) {

//For regular…

java.lang.IllegalArgumentException: Malformed \uxxxx encoding

I was getting this exception during build while running ant. Googling didn't help much and I was flummoxed because the same code was running fine till now.

My code reads a text file and does some operations on the basis of values read. It was only when I saw the text files I understood the error. I had copied the text in wordpad and saved it as .txt file. Wordpad had put lot of formatting information before and after the content. Also there was "\par" after every line, which was giving this error.

So moral of the story: if you get this exception check your properties file (or any other file that your code might be reading.)

Easiest way to print Timestamp in Java

Rather than using Calendar.getTime() we can use java.sql.Timestamp class to get the time stamp which gives date and time till millisecond precision.

System.out.println(new Timestamp(System.currentTimeMillis()));

Above will give you current timestamp in this format: 2010-07-27 16:37:45.39
