| 206 | |
| 207 | <p>iPOJO is based on a bytecode <a href="http://felix.apache.org/site/dive-into-the-ipojo-manipulation-depths.html" title="Dive into the iPOJO Manipulation depths">manipulation</a>. This manipulate is <tt>safe</tt> |
| 208 | and does not change the class semantics. Classes can still used after |
| 209 | the manipulation without iPOJO. However this manipulation is required |
| 210 | for iPOJO management. Generally, this manipulation occurs offline |
| 211 | during the packaging time. The online manipulator allows to do this |
| 212 | manipulation at install time.</p> |
| 213 | |
| 214 | <p>The online manipulator:</p> |
| 215 | <ul> |
| 216 | <li>avoids offline manipulation</li> |
| 217 | <li>supports annotations</li> |
| 218 | <li>supports XSD schema |
| 219 | <div class="" align="center"><p><img src="apache-felix-ipojo-online-manipulator_files/manipulation.png" border="0" align="absmiddle" width="640|height=300"></p></div> |
| 220 | |
| 221 | <p>This is quite useful if you don't want to add an extra packaging step, and provides the same capabilities as the "regular" way.</p></li> |

| 227 | <p>The online-manipulator is in fact an URL Handler. So, it will |
| 228 | process every bundle using a special URL prefix. To use it, just |
| 229 | follows the below instructions:</p> |
| 230 | |
| 231 | <ul> |
| 232 | <li>Install and Start the URL Handler *<br> |
| 233 | This is a requirement. You must install and start the URL handler as |
| 234 | well as iPOJO (core). The URL Handler is build by the |
| 235 | online-manipulator iPOJO sub-project.</li> |
| 236 | </ul> |
| 237 | |
| 238 | |
| 239 | <ul> |
| 240 | <li>Install a bundle using the <tt>ipojo:</tt> URL prefix<br> |
| 241 | Using the handler is quite easy. When you want to deploy a non-manipulated iPOJO bundle just use an url like |
