All the acceptable charts were integrated into the application by this time. Bar and Area chart were working perfectly. The other charts like scatter, stacked and line were not working for all the available column values. The demo was given to the mentors.
Suggestions from the Mentors:

1. The final charts except Bar and Area were displayed 12 times. This is same in IReport too. The mentors asked to study the charts in more detail. Also suggested to compare the jrxml (which is produced at runtime and saved to local drive) of the current charts with IReport jrxml and find out the reason for 12 images.

2. Saving of the jrxml can be done in the database so that it becomes more portable and secure.

3. Use the JNDI name in property file of JBoss Application Server to connect to the Database. Avoid giving anything hard coded!

4. Some discussion was also done regarding the user Interface keeping in mind the comments given by Dr. Yue. The sample chart page can be modified so that the sample image is a bit smaller in size. The user should not think that it’s the final chart he was looking for!

5. The memory full problem for JBoss and the reason for the errors thrown the server were discussed.
