!!!Prerequisites
* __[Java Development Kit (JDK)|http://java.sun.com/javase/downloads/index.jsp#jdk]__, Version __1.6.15__ or later \\ __Not Java 7!__
* __[Eclipse 3.7 "Indigo" IDE for Java EE Developers|http://eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/indigosr2]__ \\ Please make sure to get the Java __EE__ edition.\\You can also use the new Eclipse 4.2, although it is less tested with the rest of the configuration.
* __[Apache Tomcat 6|http://tomcat.apache.org/download-60.cgi]__ \\ Use the "Binary Distribution" - "Core" - .tar.gz or .zip. Do __not__ use the installer. Do __not__ use Tomcat 7
!!!Maven
Go to [http://maven.apache.org/] and download the latest version of Maven __2__. At the time of this writing this is 2.2.1. Unpack it somewhere on your system.
__Do not download Maven 3!__
!!!Eclipse
To make Eclipse work with Subversion, Tomcat and Maven, you will need a few additional plug-ins.
!!Installing Plugins
In the main menu, navigate to ''Help'' -> ''Install new software''. In the ''Work with'' field, select ''Indigo - http://download.eclipse.org/releases/indigo''. Wait for the list of available software to be retrieved, then select the following plug-ins to install:
* Collaboration
** m2e - Maven Integration for Eclipse
** Subversive SVN Team Provider (Incubation)
Click ''Next'', accept the licenses, and finish the installation. Restart Eclipse when you are asked to.
!!Selecting the SVN implementation
After restarting Eclipse, click on ''Window'' -> ''Open Perspective'' -> ''SVN Repository Exploring''.
A dialog window will be opened asking you to select an SVN connector implementation.
Select __SVNKit 1.3.5__ (or the latest available SVNKit version and finish the installation wizard.
You need to accept installing unsigned software, and restart Eclipse again when asked.
!!Setting up the Maven SVN integration
Again, go to ''Help'' -> ''Install new software''. Click the ''Add..'' button in the top right corner. In the dialog window, enter the following URL into the ''Location'' field:
%%quote
{{https://isci.informatik.uni-wuerzburg.de/eclipse/m2e-subversive/}}
/%
__For Juno:__
%%quote
{{http://community.polarion.com/projects/subversive/download/integrations/update-site/}}
/%
Hit ''OK'', then select the following software to be installed:
* Maven SCM Handler for Subversive
** Maven SCM Handler for Subversive
Like before, finish the wizard and this time __close__ Eclipse (either click ''Not now'' and exit Eclipse, or let it restart and exit from there).
!!Sysdeo Tomcat Plug-in
The Sysdeo Tomcat Plug-in allows you to start Tomcat directly from within Eclipse.
You can find it at [http://www.eclipsetotale.com/tomcatPlugin.html].
To perform the installation, download the .zip file provided at the author's homepage and unpack it into the {{plugins/}} folder inside your Eclipse installation.
The __KnowWE-App__ project is preconfigured for use with this plug-in.
%%collapsebox-closed
!!Groovy Plug-in (optional)
__You can skip this plugin if you do not use the plug-ins using Groovy (e.g., Refactoring, WISEC, CI,...).__
To install the plugin, you need to add a new ''Software Update Site'' in Eclipse:
In the main menu, navigate to ''Help'' -> ''Install new software''. In the dialog, click ''Add...'' and enter the following URL into the ''Location'' text box:
For Eclipse 3.6
%%quote
{{http://dist.springsource.org/milestone/GRECLIPSE/e3.6/}}
/%
For Eclipse 3.5
%%quote
{{http://dist.springsource.org/release/GRECLIPSE/e3.5/}}
/%
Then, you just have to select and install the "Groovy-Eclipse Feature" which you can find under
%%quote
Groovy-Eclipse -> Groovy-Eclipse Feature
/%
Currently, Groovy is only needed for the Project "KnowWE-Plugin-Refactoring". It is highly recommended to install this plugin because otherwise, Eclipse will show errors.
Alternatively, close the project. This is not recommended, because if you change something on the core projects, you will forget eventual changes which concern also the refactoring plugin.
In either case, Maven is able to compile the refactoring plugin and you also will be able to run its maven tests, with or without having installed the Groovy-Plugin for Eclipse.

!!!Preparing your workspace
!! Eclipse settings
Start arguments: \\
Maven needs Eclipse to run in a JDK, not in a JRE. Start Eclipse with the -vm parameter, for example: \\
"C:\Program Files\eclipse\eclipse.exe" -vm "C:\Program Files\Java\jdk1.6.0_17\bin\javaw.exe"
You can find the following Eclipse settings in the main menu at ''Window'' -> ''Preferences''.
%%( background-color: #fcaf3e; border: 1px solid #f57900; padding: .5em; )
__IMPORTANT:__ Maven: \\
''Maven'' -> ''Installations''. Click on ''Add...'' and select the path where you unpacked Maven. Be sure that your external Maven version is checked.
%%
Encoding: ''General'' -> ''Workspace'' -> ''Text file encoding'': "UTF-8"
Disable certain compiler errors: ''Java'' -> ''Compiler'' -> ''Errors/Warnings'' -> ''Deprecated and restricted API'' -> ''Forbidden reference:'' "Warning"
[{Image src='Workspace/saveactions.png' width='232' height='202' align='right' link='http://d3webwiki.informatik.uni-wuerzburg.de/attach/Workspace/saveactions.png' caption='The save actions that have to be enabled'}]
!Comment format:
Get the [codetemplates.xml] attached to this page and import it: ''Java'' -> ''Code Style'' -> ''Code Templates''
Enable: ''Automatically add comments for new methods and types''
(If your login name is not meaningful, you have to change the comment template for ''Type'', as your login name is used as author name)
!Code format settings:
Get the [code_conventions.xml] attached to this page and import it: ''Java'' -> ''Code Style'' -> ''Formatter''
To enable automatic formatting, certain actions have to be carried out on saving: ''Java'' -> ''Editor'' -> ''Save Actions''
The screenshot on the right shows the actions, that have to be activated.
! Tomcat plug-in:
''Tomcat'' -> ''Tomcat Version:'' Select your Tomcat version here\\
''Tomcat'' -> ''Tomcat Home:'' Choose the directory where you unpacked the Tomcat zip\\
''Tomcat'' -> ''Context declaration mode:'' "Context files" (do __not__ select server.xml!)\\
''Tomcat'' -> ''JVM Settings'' -> ''JRE:'' check that the correct JRE is selected
''optional'': Set larger heap size for tomcat:\\
''Window'' -> ''Preferences'' -> ''Tomcat'' -> ''JVM Settings'' -> ''add to JVM parameters'' -> set for example: -Xms1g -Xmx1g\\
Read for your exact personal settings: [http://javahowto.blogspot.com/2006/06/6-common-errors-in-setting-java-heap.html]
''recommended'': Set Tomcat to use UTF-8 (necessary for special characters like german umlauts in page names for example):\\
You have to edit server.xml of Tomcat (is in the conf-directory of Tomcat). Please add to\\
{{{<Connector port="8080"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
debug="0" connectionTimeout="20000"
disableUploadTimeout="true"/>}}}\\
the term __URIEncoding="UTF-8"__.\\
It should look like that:\\
{{{<Connector port="8080"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
debug="0" connectionTimeout="20000"
disableUploadTimeout="true"
URIEncoding="UTF-8"/>}}}\\

!! Adding the SVN repositories
''Window'' -> ''Open perspective'' -> ''Other…'' -> ''SVN Repository Exploring''.
Repeat the following step for each of the listed repository URIs: \\
In the ''SVN Repositories'' view, perform a right click, select ''New'' -> ''Repository Location''...
__Read/write access (account necessary):__
%%quote
{{https://isci.informatik.uni-wuerzburg.de/svn/d3web-core}} \\
{{https://isci.informatik.uni-wuerzburg.de/svn/d3web-KnowWE}} \\
{{https://isci.informatik.uni-wuerzburg.de/svn/Research}} \\
/%
__Anonymous access (read only):__

!! Checking out the code
Select the three main projects (__d3web__, __d3web-KnowWE__, and __Research__) as well as __KnowWE-App__ from inside the three repositories. They are in the trunk/ folders respectively. Use {{CTRL}} or {{Cmd}} to be able to select multiple projects. Right click one of the projects and select ''Check out as Maven Project…'' and click ''Finish''.
!!! Building KnowWE
!! Create local preferences for JSPWiki
Copy {{KnowWE-App/src/resources/local/WEB-INF/jspwiki.properties.default}} to {{jspwiki.properties}} in the same directory. __Do not rename it in Eclipse.__ \\
In {{jspwiki.properties}}, edit the settings for your local environment. The three most important settings are at the top.
!!Package KnowWE-Resources
Right click 'KnowWE-Resources' project -> ''Run as'' -> ''Maven package''
!! Create a run configuration for building the wiki
Right click on "KnowWE-App", select ''Run as'' -> ''Maven build…''. \\
A dialog will show. Set the following settings: \\
Goals: {{clean install}} \\
Profiles: {{local core-plugins}}
Enable checkbox "Resolve Workspace artifacts"
!! Updating the Tomcat context
Right click on "KnowWE-App" -> ''Tomcat project'' -> ''Refresh context in Tomcat''
!!! Starting KnowWE
You can now start Tomcat using the ''Start tomcat'' toolbar button or menu entry. Open the following URI in your browser:
%%quote
http://localhost:8080/KnowWE/
/%
!!!Troubleshooting
!! Compile errors after first build
Sometimes you get errors like:
{{{
Cannot nest output folder 'd3web-Distributed/target/classes' inside output folder 'd3web-Distributed'
}}}
If this happens, close and open all affected projects. Alternatively, you have to do the following steps:
# Remove the affected projects from the workspace without deleting them, by selecting 'Delete' from the context menu and unchecking the checkbox.
# Import the project back to the workspace:
## Menu: File->Import...
## General: Existing projects into workspace
## As root directory select the project directory itself, e.g. <workspacedir>\d3web-KnowWE\d3web-distributed.
## Select the project in the list.
## Click 'Finish'.
# Repeat step 2 for every project that was affected.
!! ClassCastException on startup
You might encounter the following exception:
{{{
java.lang.ClassCastException: org.apache.catalina.util.DefaultAnnotationProcessor cannot be cast to org.apache.AnnotationProcessor
}}}
__Workaround:__ In the folder where you unpacked Tomcat (e.g. {{/usr/local/apache-tomcat-6.0.20/}}) you can find a directory called {{conf}}. In there is {{context.xml}}. Add follwing statement into the {{<Context>}} element:
%%quote
{{<Loader delegate="true"/>}}
