Allow to insert data in jasper

JDBC data sources in JasperReports Server are created by default with autoCommit=false and readOnly=true.

You can change the default flags to see if that would result in the the stored procedure working properly. To do that, they would need to add the following properties to the jdbcDataSourceServiceFactory bean in WEB-INF/applicationContext.xml:

<property name="defaultAutoCommit" value="true"/> 
<property name="defaultReadOnly" value="false"/>

For JNDI, you will have to do this on the application server level. For example, in Tomcat, you will have to add “defaultReadOnly=false” and “defaultAutoCommit=true” to the resource entry located here: conf/Catalina/<host>/jasperserver-pro.xml

The server needs to be restarted for the changes to apply.
