please help me regard this

I am willing to help but first this. Please first learn how to program and use Java. This is a very simple and basic Java error.

 

It says that it can't find a certain package, namely net.sf.jasperreport. If you had searched this forum or visited the jasperreport site you would have discovered that you need to put the jasperreport*.jar file in your classpath. This will solve the problem.

Hello,

 

I am getting the same error. I do have the jasperreports .jar file in the classpath. I understand Tomcat is not finding the jasperreports compiler but can you give me any pointers on which setup I might be missing?

 

The jasperreports works fine in Eclipse environment (where I am using JasperAssistant to preview the report). But when I use a servlet to display the report in pdf in the browser, I get this error.

 

Any help will be greatly appreciated.

 

Thanks,

Nicky

See this FAQ.

 

HTH,

Thanks Lucian. I included the jdt compiler jar and it works now.

 

There is something I dont understand though...I started working on this current project about a year ago and used jasperreports-1.2.2 with Tomcat 4.1. Every setting was the same as it is now and it was working. I had checked it into CVS. And now when I had to return to this project, I just pulled everything down from CVS. The jdt compiler was not included then. Can you suggest why it might have been working previously?

 

Thanks a bunch again for your help.

Are you using the same Tomcat version?

 

Tomcat also uses the Eclipse JDT classes to compile JSPs, and maybe older Tomcat versions were including the JDT classes on the web applications' classloaders.

Lucian
