| h2(#Installation). Installing the Eclipse OCL Examples and Editors |
| |
| The OCL console and editors are not part of the core OCL functionality included in the |
| Eclipse Modeling Tools Package, so although you may have OCL installed and be able |
| to read this tutorial via the *Help->Help Contents->OCL Documentation*, you may |
| not have the OCL examples installed. |
| |
| An easy way to test whether you have the OCL Examples installed is |
| to right click on a *.ecore file and see whether |
| *OCLinEcore (Ecore) Editor* appears in the *Open With* submenu. |
| |
| If OCL is not installed at all, or if just the examples are not installed, |
| the following installation step will automatically install the OCL Examples |
| and all required projects such as *EMF*, *UML2*, *MWE2*, *Xpand* |
| and *Xtext*. |
| |
| Left-click on *Help* in the title-bar then left-click on *Install New Software...* |
| and select the *Indigo - http://download.eclipse.org/releases/indigo* update site |
| from the pull-down menu to *Work with* and be patient while the available updates |
| are identified. Then select *OCL Examples and Editors* from the *Modeling* |
| category. |

| Select *Restart Now* when prompted to do so. |

| h3. Troubleshooting |
| |
| Eclipse Modeling Projects have a large number of classes and so require a |
| large amount of PermGen space on a Sun JVM. If you are using default Eclipse |
| startup settings you are liable to encounter OutOfMemoryExceptions. Therefore |
| follow the advice in "How do I start Eclipse":http://wiki.eclipse.org/IRC_FAQ#How_do_I_start_Eclipse.3F |
| and set XX:PermSize to at least 64M, either on your Eclipse command line, or your |
| Eclipse shortcut or in the *eclipse.ini* adjacent to *eclipse.exe*. |
