Hi RB,

 

I tried adding 'chartfx70/temp'  under my application folder 'CRMApp' and i have the config set as below

  <Relative>/chartfx70/temp</Relative>
  <AxCompat>True</AxCompat>
  <RequiredRoot>.</RequiredRoot>
  <DefaultHandler>ChartFX.WebForms.Internal.OutputFileHandler,ChartFX.WebForms</DefaultHandler>
</CfxIESettings>

Following is the error message im getting.

I assume that it cannot identify the 'temp' directory

[Nullpointer in ChartFX7]

[Nullpointer in ChartFX7]

Hi 

We are using ChartFX 6.5 currently, for my new requirement i required to have AJAX functionality with chartFX,so i tried to download ChartFX 7.

 

I tried to install the sample application of chartFX7, i can run the sample application in TOMCAT5.5 without any issues.

When i tried to run chartFX7 in my development weblogic env. i get the following error

java.lang.NullPointerException
  at com.softwarefx.sfxnet.internal.km.I(SourceFile:119)
  at com.softwarefx.chartfx.server.internal.aa$b.a(SourceFile:111)
  at com.softwarefx.chartfx.server.internal.aa.a(SourceFile:45)
  at com.softwarefx.chartfx.server.internal.ej.a(SourceFile:70)
  at com.softwarefx.chartfx.server.internal.Chart.m(SourceFile:4274)
  Truncated. see log file for complete stacktrace

 

Following are the things i have done

1. i have copied ChartFX 7 license and config file in my WEB-INF/lib ,

2. i copied all the chartFX 7 related JAR file from samples into my WEB-INF/lib folder

3. i made sure there is no older version of (chartfx6.5) JAR file in server cache or lib folder

 

Am i missing something?, your help would be appreciated.
