Well, it looks like this is the line of code being executed: return newInstance(contextPath,classLoader,Collections.String,ObjectemptyMap()); Tomcat normally dumps out at least the value of its JRE_HOME env var upon startup, can you verify that it's really using 1.6?

1. Error is complaining on the following lines of the code.
Vector advVec=new Vector();
if (rs.getObject(ADVISOR) != null)
{
XMLType poxml = (XMLType) rs.getObject(advisor);
String advisorstring = poxml.getStringVal();
// System.out.println(the advisor string in
reportbeanstudent is + advisorstring);

How can I set the JRE_HOME? Why is it null? I am very new to this. Please point me to fix this.
