Error while creating a DrillDown chart

[deeptic]

Hi,

 

 

 

I am creating the following drill down chart using my own tables:

 

 

 

 

 

 

 

 

However, I get this error in Tomcat:

 

 

 

 

 

exception

 

 

 

org.apache.jasper.JasperException: Unable to compile class for JSP:

 

 

 

An error occurred at line: 6 in the generated java file

 

Only a type can be imported. com.fusioncharts.FusionChartsHelper resolves to a package

 

 

 

An error occurred at line: 89 in the jsp file: /DBExample/Default_New.jsp

 

FusionChartsHelper cannot be resolved

 

86: totalOutput=rs2.getString("TotOutput");

 

87: }

 

88: // Encoding the URL since it has a parameter

 

89: strDataURL = FusionChartsHelper.encodeDataURL("Detailed_New.jsp?Emp_Month="+factoryId,"false",response);

 

90: //Generate

 

91: strXML += "";

Is there something that I have missed. Please guide.

 

 

 

Also is there a location for FusionCharts Helper in the downloaded package. I am unable to find it. Am I supposed to make any changes in the same?

Hi,

 

 

 

Can somebody from the FusionCharts team guide me please.

Hi,

 

 

 

I have been able to resolve the error. I had to make a change in this part of the code:

 

 

 

strDataURL = FusionChartsHelper.encodeDataURL("Detailed_New.jsp?Emp_Month="+factoryId,"false",response);

 

 

 

I changed it to

 

 

 

strDataURL = encodeDataURL("Detailed_New.jsp?Emp_Month="+factoryId,"false",response);

 

 

 

i.e., I removed the 'FusionChartsHelper'

 

 

 

But, I would like to understand one thing. If the example given in the package works by including 'FusionChartsHelper' in the code, why doesn't it work on my table - I mean I had to exclude 'FusionChartsHelper' to compile the code without any errors

Hi Deepti

The code in the samples has this line of import.

<%@ page import ="com.fusioncharts.FusionChartsHelper"%>

and the corresponding classes are present in WEB-INF/classes folder of the web application.

Please verify that you have the import statement and the necessary class in your web application.

Hope this helps!
