KnowWE is based on JSPWiki and therefore needs an jspwiki-custom.properties to configure some basics. Copy the file {{KnowWE-App/src/resources/local/WEB-INF/classes/jspwiki-custom.properties.default}} into the same folder with the same name, but remove the suffix '.default'. For starters, you only need to set a the {{var.basedir}} to point to a wikicontent (folder with the wiki pages). If you don't have a wikicontent yet, you can start out with the one provided in the distribution from [Downloads#Latest Releases and Builds]. In the zip, extract {{/KnowWE/KnowWE-Tomcat.zip/wikicontent}} to the path you specified as the var.basedir in your jspwiki-custom.properties.

!!Groovy Plug-in (optional)
* Import d3web-KnowWE project as a Maven project. File -> Import -> Existing Maven Projects
* Window -> Preferences -> Java -> Installed JREs. Add Adoptium JDK and select it
* Make sure that the ‘JRE System Library’ of each maven project is set to ‘JavaSE-14’ compliance level. Also make sure that in maven project properties, the JDK compliance is limited to 14 in the ‘Java Compiler’ section
* In KnowWE-App project, under Maven Dependencies properties -> Use Maven Project settings -> Active Maven Profiles, set ‘core-plugins’ as active profile. This will copy the core dependencies to the KnowWE-App application when deploying it into Tomcat
* Under KnowWE-App project properties -> Java Build Path -> Source, add the next Folder: src/resources/local/WEB-INF/classes. This will copy the jspwiki.properties to the KnowWE-App application when deploying it into Tomcat. Also follow the ste [Create copy of jspwiki-custom.properties|How-To Create Your Own Workspace#Create copy of jspwiki-custom.properties] of the IntelliJ-part of the guide.
* Add the run configuration to build the project: Run -> Run Configurations -> Double click on Maven Build to create a new configuration. Set the Base directory: ${workspace_loc:/KnowWE}; Goals: install; Profiles: core-plugins; Skip Tests. Under JRE -> Execution environment, select JavaSE-14. Select Maven Runtime -> External (It seems that EMBEDDED flavour is not well managed by Eclipse and the compilation is not constrained to version 14)
* Click Run to build the project
* Under the tab Servers, add a Tomcat9 web application server and select the location where you downloaded it. Add KnowWE-App as resource to the right ‘Configured’ section. Under Edit Server Runtime select as JRE the installed JDK 1.7.
* Click Start to launch the server. Open the application in http://localhost:8080/KnowWE-App

__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''.
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='saveactions.png' width='232' height='202' align='right' link='/attach/How-To%20Create%20Your%20Own%20Workspace/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"/>}}}\\

!! Checking out the code
Select the three main projects (__d3web__, __KnowWE__, and __Research__) as well as __KnowWE-App__ from inside the trunks of 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"/>}}
