Error occured while deploying on coldfusion application

[Hemanshu]

Hello

My application is suppose to print graphs in pdf format using iText library on web based environment.

When I deploy my application on Linux I get following errors -

Have you put the jar files for jfreechart into the lib directory of your webapp?
What is your servlet container setup, and how are you deploying the webapp?

Hello David

I am using coldfusion to invoke my java component.

Yes, I included jCommon and jFreeChart jar files in the library along with iText and MsSQL library files.

My java component returns me the pdf file path with charts embeded on it. This works perfect when I create pdf file using my java program. The only problem is when I integrate it with my coldfusion program.

This is not the first time I am invoking iText using coldfusion. I have done it before several times successfully.

I will really appreciate your help on this as I am stuck here.

thank you

Hello

I figured out that problem is only in case of deploying jFreeChart on web based environment. How did I arrive at this conclusion?

1. I am embedding jFreeChart on pdf file created using iText. If I create PDF file minus charts, I do not face any problem

2. When I use jFreeChart through standalone java program it works fine.

So the problem remains - how to deploy jFreeChart and jCommon in web enviroment.

Please advise.

Hello Friends

I am still seeking someone to help me. I tried all the possible ways but no luck.

The error message you get under windows doesn't look like it is related to JFreeChart. Under Linux, you might be running into the "headless" Java problem, there is some info in the FAQ about it.

Hello David,

I tested my program- I removed jfreechart library and tried creating PDF file using iText library it works as desired on windows and linux environments. The moment I plug jfreechart and jcommon again the errors start coming.

Do you suggest that we should run coldfusion over tomcat instead of jrun? I am thinking of trying that option. Can you advise?

regards

Hemanshu
