Took away crimson.jar from the classpath so that it uses xerces.jar, restarted the server & it works fine now.
Summery:
If one sees this message
"Valid documents must have a <!DOCTYPE declaration.", 2 possibilities :
1. malformed XML file
2. XML file not found ( silly, one should expect a FileNotFound exception)
For the malformed XML make sure:
1. Encoding is correct (if none mentioned , then guesses UTF-8)
2. There is no non Unicode character in the XML doc

Hi ,
I am at a loss when I read the following message in my system.out log.
log4j:WARN Parsing error on line 1 and column -1
log4j:WARN Valid documents must have a <!DOCTYPE declaration.
log4j:ERROR Parsing error on line 1 and column -1

in WEB-INF/lib I have:
crimson.jar jaxp.jar jconfig.jar log4j-1.2.8.jar xerces.jar
in WEB-INF/classes I have:
log4j.dtd
The container is WEBSPHERE 4.06 AE.
I copied the needed xml, dtd & the jar files from an application where log4j is working fine.
Is log4j suppoesed to use the crimson purser or the SAX ?
Any suggestion is appreciated.
Thanks.

Hi ,
I have a web application ( DBBeans --Servlet --JSP) .
I need to incorporate a functionality such that:
if the admin needs to send out a message to the app-logged in users , for example : "Application will shutdown in 10 mins. Please save your work and logout of the app: Message8" and can control the number of times this message is shown to a any users, how can I do that in the app without using a full blown messaging service (JMS, MQSeries) .
For now, I have a property file where I can put a string (example:Message8) which the app will pick up when it loads any of the jsp and show it in an alert box, but I have no way to track/control as to how many times a user should see the message !
Possibly I can modify the code in the controller (servlet) and keep track in a session object but thats still possibly an old way of doing things.
I was thinking of some module like log4j that I could plug into the app for the messaging .
Any suggestion ?
Again , many thanks .

Hi there ,
While implementing MVC architecture ,
I made an abstract ParentController.java which is extended by ApplicationController.java. In the ApplicationController I am doing :
// get the application object
ServletContext app = getServletContext();

// select login.jsp as the template
RequestDispatcher disp;
disp = app.getRequestDispatcher("index.jsp");
and at compile time I am getting:
ApplicationController.java:46: cannot resolve symbol
symbol : method getServletContext ()
Any idea? Thanks in advance for your comments .
Here are the code of the 2 classes :

Thanks Mark Howard. Seemed to be that these attributes are not availabe for servlet2.2 ( or equivalent version of JSP). In the webSphere that I have access to , the Servlet.jar is missing the javax.servlet.error.* package! So I am stuck.
Again , thanks so much for the direction.

Hi there ,
I have an error page for the jsp application.
In that error page I need to log the "file name or the URL" of the page that called the error page.
request.getRequestURI()
gives me the file name of the error page .
Any suggestion ?
Thanks.
ML

Thanks Mark. Your suggestion helped me reEvaluate my code and found that the method signature was wrong.
request.getRequestURL()
is now request.getRequestURI()
Thanks.

HI,
I am trying to get a reference to the requerst object so that I could get/LOG the page URL.
I tried:
1.
HttpServletRequest req ;
System.out.println("[ Debug Mode Enabled. Request in execution = " +req.getRequestURL().toString() +req.getQueryString() );
2.
System.out.println("[ Debug Mode Enabled. Request in execution = " +request.getRequestURL().toString() +request.getQueryString() );
None worked. Compile error.Cant get a handle to the request obj. Any suggestion ?
Trying to do this the a JSP page.
Thanks.

I am writing a mehod in a bean which returns a Set of "All" generations of subBusinesses ( Children) for a given business.
/************************************/
public Set getAllChildren3( String p_orgId){

Object l_busParentObj1 = null;


Map l_tempMap1 = new HashMap();
Set l_tempSet1 = new TreeSet();



// Getting all the 1st gen children
l_tempMap1= (Map)getChildBusMap( p_orgId) ;


if ( l_tempMap1.size()>0)
{
tempSet.addAll(l_tempMap1.keySet());
l_tempSet1.addAll(l_tempMap1.keySet());
for (Iterator iTemp1=l_tempSet1.iterator(); iTemp1.hasNext(); )
{
l_busParentObj1= iTemp1.next();
if ( isThereChildBus(l_busParentObj1.toString()))
getAllChildren3( l_busParentObj1.toString());
}
}
return tempSet ;
}
/************************************/
// the method "getChildBusMap(" returns the immediate subBusiness( 1st generation Children) for a given Business
// where "tempSet" is a global reUsable Set Object, currently using only in this method.
The method works just fine , but I hate the fact that I had to use aglobal variable ! Its lot of work to keep track of global variables . Do you have any suggestion as to HOW I COULD USE A LOCAL VARIABLE in this recursion in place of "tempSet".
Any other design suggestion ?
Thx in dvance for reading this.
