• Can configure environment variables (e.g. JAR files, property files, etc.)
• Have all the necessary tools to create Java applications (JDK, IDE, etc.)
• Has access to the Strategy SDK documentation.

Environment. The Strategy Web JAR files can be found under:

• Strategy Web Universal (JSP): {web_root}/WEB-INF/lib directory.
• Strategy Web (.NET): Program Files\Common Files\Strategy directory.

Note:
More elaborate programs will require additional library files and are out of the scope of this document.
Using the Web Customization Editor to create a plug-in
Strategy SDK provides a Web Customization Editor that can be used to create a customization plug-in. The following steps show how to create the plug-in and deploy.

• Launch the Web Customization Editor. 
• Create a new plug-in and give it a meaningful name. For example: ModifyErrorMessage. (For step by step instructions on creating a new plug-in, please navigate to Home > Web SDK > Customizing Strategy Web > Web Customization Editor > Features and Customizable) 
• Click in Strategy Web Configuration inside the Application Settings view to expand the hierarchical tree. The expanded list comprises the different settings that can be modified to perform customizations. 
• Navigate to Pages > error(Error page).  Double-click on error(Error page), the editor should open.
• Click on the Template Properties tab.
  

• On the Page Templates section, on the Default tab, click the Modify button for the Template File: (by default is defined as /jsp/Error_Template.jsp).
  

• Click ‘YES’ if prompted “Editing this file will create a copy in your plug-in folder and this copied file will be opened for editing.  Do you want to continue?”  The Error_Template.jsp file should be open.
• Minimize Eclipse.
• Navigate to the Strategy Web folder location on the Web Server machine.
• Copy the following 2 files from ..\jsp to the following location ..\plugins\ModifyErrorMessage\jsp
  
• Error_FullContent.jsp
• JSP_Error.jsp
• Edit the ..\plugins\ModifyErrorMessage\jsp\JSP_Error.jsp file.  Modify the following line:
  
  Sample Code/Error
  
  

  
  <div class="mstrAlertMessage"><web:errorValue property="message"/></div>

  
  
  
  to the following code:
  
  Sample Code/Error
  
  

  
  <div class="mstrAlertMessage"><web:scriptlet>document.write("Place message you want your users to see here.<br>");</web:scriptlet></div>

  
  
  
  
• Save the changes to the file.
• Restart the Web Server.
