I'm banging my head against a wall trying to get some dynamic information
from the container session into a BIRT report so that I can set the JNDI
property based on runtime information. I started using the examples from
the website for getting session variables, but the BIRT logs report null
when using:
reportContext.getHttpServletRequest() in javaScript.So I thought I'd do a
little debugging in Eclipse by sending the ReportContext to a java class and
interrogating the ReportContext. This is the Javascript in datasource
before open:
importPackage(Packages.com.ghd.admin.util)
DataSourceClass = new ExternalSecurity(reportContext);
this.setExtensionProperty("odaJndiName",DataSourceClass.getJndiName());
I'm using Ecplise (of course) and Sysdeo as the tomcat plugin for debugging.
I set a break point in the constructor, adn can get alot of great
information out of the IReportContext object, but the HttpServletRequest is
still null. Here is the ExternalSecurity class.
_______
package com.ghd.admin.util;
import javax.servlet.http.HttpServletRequest;
import org.eclipse.birt.report.engine.api.script.IReportContext;
public class ExternalSecurity {
String jndiName;
public ExternalSecurity(IReportContext reportContext) {
Object object = reportContext.getHttpServletRequest();
if (object == null){
System.err.println("getHttpServletRequest returned null");
}else{
HttpServletRequest hsr =
(HttpServletRequest)reportContext.getHttpServletRequest();
String pjndiName =(String) hsr.getSession().getAttribute("jndiName");
setJndiName(pjndiName);
}
}
/**
* @return the jndiName
*/
public String getJndiName() {
return jndiName;
}
/**
* @param jndiName the jndiName to set
*/
public void setJndiName(String jndiName) {
this.jndiName = jndiName;
}
}
I can't help but think that this is a some glitch with my Development
Environment, otherwise many more people would have reported problems. I did
see another similar issue on another forum
http://www.eclipsezone.com/eclipse/forums/t75089.html with the same error
message in the BIRT logs [Cannot call method "getSession" of null]. I also
a saw a Bugzilla issue that may be related
https://bugs.eclipse.org/bugs/show_bug.cgi?id=123705 having to do with class
loaders, but I could not really gleen the fix.
Any help would be much appreciated,
Thanks,
Fred Forester
