RE: JspTagException- Stream closed
Here is the body of the method doEndTag(). The exception is thrown for line number 146, which is this.iter = null; of the reset method.
public int doEndTag()
throws JspException

this.jdField_bodyContent_of_type_JavaxServletJspTagextBodyContent.writeOut(this.jdField_bodyContent_of_type_JavaxServletJspTagextBodyContent.getEnclosingWriter());
}
catch (IOException localIOException)
{
this.jdField_pageContext_of_type_JavaxServletJspPageContext.getServletContext().log(Res.getString(4), localIOException);
throw new JspTagException(localIOException.getMessage());

The RowSetIterate tag is declared in the JSP itself. All the JSPs having this RowSetIterate tag is throwing Stream closed exception.

Where is the row set itself declared? In the JSP? In a servlet somewhere that executes before the JSP?
In general, I wouldn't recommend making any JDBC calls from within a
JSP: I prefer to take care of all data acquisition in a servlet (or
similar) before delegating the creation of a response to the view layer. But that's just me.

I'll eat my hat if "this.iter = null;" is throwing a JspTagException
(especially one whose stack trace does not include the "reset"
method). I think you are looking at source code that does not match
the exception stack trace you are seeing.
You should be seeing another stack trace (in the application log,
according to the source I see above) that includes full details of the
IOException that is being caught and re-thrown as a JspTagException --
without including the "cause" when creating the new exception. Bad
Oracle! Bad!
If you find that exception, it might give you better information about
why it's happening in the first place.
