Changing Eclipse Workspace Directory

Recently I moved my entire Eclipse installation directory but the workspace was still getting created in the older location only. And worst there was no option to select the Workspace directory in the Window->Options->Workspace menu. To change the workspace location in Eclipse do this. Goto ECLIPSE_HOME\configuration\.settings directory, edit the org.eclipse.ui.ide.prefs file and change the RECENT_WORKSPACES value to the desired location. If you want that Eclipse prompts you to select workspace when you start it, change the SHOW_WORKSPACE_SELECTION_DIALOG value to true. And you are done!

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()) { //Fo...
