JasperReports 0.4.6 and common-xxx.jar

2003-05-12 10:26

I got webapp that came with JasperReports 0.4.5 working. Now, I updated jasperreport.jar in WEB-INF/lib/ directory to version 0.4.6 and started getting the following error:

Error: 500

Internal Servlet Error:

It would help if you could list all the libraries that need to be updated when upgrading to the next JasperReports version.

Yes, I'm aware of this problem.

In fact, since 0.4.6, JasperReports uses the

SAX 2.0 API through JAXP.

I should put this into the requirements.

Some older versions of JAXP do not have

the SAXParser.getXMLReader() method.


Apparently, your application uses such a version of

the JAXP API, probably due to the fact that it is

found somewhere on the server's classpath.

I saw this problem with tomcat 3.2 for example.


A solution would be to upgrade those jars that contain JAXP in your webserver.


I hope this helps.
