Cannot find org.w3c.tidy.Tidy

sratay

I am integrating BIRT into a web application and getting a class loading exception when deploying to my test environment. I can get the report to successfully generate as a PDF on my local development environment. However, when I deploy and build on my test environment, I get the following class loading exception. I don't see this class either in my WEB-INF/lib directory or in the WEB-INF/platform/plugins directory. Could I be loading the class from my Eclipse install when running locally? Maybe some kind of file permissions issue? Has anyone else run into this issue and come up with a solution?

My local development environment is Windows, and the test environment is Linux. I'm running Tomcat 6 with Java 6. I'm running BIRT 2.2.2.

Thanks, Steve

If you are integrating the ReportEngine into your web application the directory structure for your web application should look something like:
-webapp
----images
----reports
----WEB-INF

---

lib

---

platform

---

plugins

---

configuration

tidy.jar is located in a directory under the configuration directory. Have you included the configuration directory in your webapp?

We are using BIRT 2.2.1.1 and in the Tidy.jar is always located in

pluginsorg.eclipse.birt.report.engine_2.2.1.r22x_v20070924.jarlibTidy.jar

No matter if I use BIRTReportFrameworkSDK or BIRT-Runtime (both ReportEngine and WebViewerExample).

The Tidy.jar under configuration seems to be a runtime copy of the deployed and running report-web-viewer.

We have sometimes the same problem (often solved after restart of the application-server) if we deploy the ReportingWAR inside an EAR file in WAS61.

When deploying BIRT on WebSphere, make sure you set the Classloader mode to PARENT_LAST and the WAR Classloader Policy to Application.<br />

Hi
I also had a similar problem. and I provided write access to the user tomcat on the directory WEB-INF/platform and everything goes fine. Seems like BIRT is writing/extracting some files in the configuration directory and creating a workspace folder also.
