Hi JP,
If you use,"apply_amps.bat" it will delete the exploded directory of alfresco and share folder.
Once you restarted tomcat, make sure, you've exploded directories of alfresco and share are exist.
The best way to install add-on is, using AMP and this report dashlet does not have amp file for share. So, try the below steps.
Approach 1:
1) First take back-up of alfresco.war, share.war and alfresco.db (if required)
2) Install the report-dashlet-alfresco-extension.amp using apply_amps.bat file.
3) Restart the server
4) Now, tomcat will expand alfresco.war and share.war into alfresco and share folders respectively.
5) Stop tomcat.
6) Place the report-dashlet.jar file onto this path: C:/Alfresco/tomcat/webapps/share/WEB-INF/lib
7) Start tomcat again.
Approach 2:
1) First take back-up of alfresco.war, share.war and alfresco.db (if required)
2) Place the report-dashlet.jar file onto this path: C:/Alfresco/tomcat/webapps/share/WEB-INF/lib
3) Modify apply_amps.bat file, not to delete share folder. (Replace "rmdir /S /Q "%CATALINA_HOME%\webapps\share"" with "rem rmdir /S /Q "%CATALINA_HOME%\webapps\share""). So, share folder will not be deleted.
4) Install the report-dashlet-alfresco-extension.amp using apply_amps.bat file.
5) Make sure that Share folder is not deleted.
6) Restart tomcat.
I will prefer Approach 1 rather than Approach 2.
Hope this helps you !
