Hello,

Here goes your answers.

First Question:
To use the Integration Studio to edit java extensions you need to:

• Install eclipse and the apache ant,
• Using the Integration Studio options window (https://www.outsystems.com/help/integrationstudio/6.0/Getting_Started/Options_Window.htm) configure the setting "J2EE Integrated Development Environment" to point to the eclipse directory and the "J2EE Compiler Tool" to point to the ant.bat file inside the bin directory of the ant folder.
• Then click the "Edit Source Code J2EE" in the toolbar to open the Eclipse IDE. Simply close the Eclipse IDE's welcome screen and a workspace containing your java extension code should appear.

Second Question:

• Please check the System Requirements document for your specific Integration Studio version. For Integration Studio 6.0 (https://www.outsystems.com/goto/System-Requirements-6.0) the supported Visual Studio versions are 2008 and 2010 and for 5.1 (https://www.outsystems.com/goto/System-Requirements-5.1) the supported Visual Studio version is 2008.
