Hi,

 

 

 

I am following a documentation on Using FusionCharts with JSP > Plotting data from a database. Please find the same in:

 

 

 

https://www.cre8ivewebsites.com/js/3rdparty/FusionCharts/Contents/JSP_DB.html

 

 

 

 

 

 

 

I am trying to run the BasicDBExample.jsp file in Tomcat. But, I keep getting this error:

Please verify that you have performed the step 5 of the readme which says:

5. In order to configure the MySQL database:

Open the file "CATALINA_HOME"/webapps/FusionCharts_JSP/META-INF/context.xml. 

In this xml,please change the username,password,url according to your database.

Hope this helps! :)

Hi Srividya,

 

 

 

Yes, I had made the changes initially. But I realized that the changes weren't being reflected in the folder in WEBAPPS. So, I worked on it ; I made all the changes before loading the folder in WEBAPPS. This has been successful; the chart is now visible in the browser.
