Re: Losing Session

Mon, 24 Sep 2001 20:55:43 -0700

HI Vibha,
 
What is the version of the browser you are using? I faced the same problem with IE 4.0. IE 5.0 works fine in taking the same session to the child window. But this was in servlets. Not too sure about JSPs.

Subject: Losing Session

Hi All,
 
I am in a deep problem.
I am using the following code:
 
 
 window.open('/NasApp/wisper/AuFindSrv?rbAuditType='+lsAuditType+'&hdFlagAction='
  +FindAuditForm.hdFlagAction.value
  +'&hdisPlan=false'+'&hdCurrPage='+FindAuditForm.hdCurrPage.value
  +'&hdnMode=Print'+'&lsSessionId='+lsSessionId+'&hdLeadAuditorId='+FindAuditForm.hdLeadAuditorId.value
  +'&hdDunsId='+FindAuditForm.hdDunsId.value+'&txtFromDt='+FindAuditForm.txtFromDt.value+'&txtToDt='+FindAuditForm.txtToDt.value,'ReportFormat',
      'location=no,scrollbars=no,width=400,height=150');
 
 
When I go to thsi servlet. I do req.getSesssion(false). But my session is null, though it was present before I clicked on teh button in teh JSP before using window.open.
Does teh session get lost in window.open?
Is there a way out??
Please help
 
Regards,
Vibha

Hi Shivaraj...
 
thanks for your patience on this one... i'm gonna run down what i know that i've got now...
 
the two classes contained in this mail (below) are both in the same directory....
 
    C:\Program Files\Jakarta Tomcat 4.0\webapps\begjsp-ch07\WEB-INF\classes\com\wrox\library
 
the first class Book compiles without a hitch, but the subclass ChildrensBook is still giving me grief...
 
 
when attempting to compile it through forte I get...
 
    WEB-INF/classes/com/wrox/library/ChildrensBook.java [3:1] Class Book not found in type declaration or import.
    public class ChildrensBook extends Book {
                                   ^
    1 error
 
 
and when trying the same through the console, with the command:  javac ChildrensBook.java
 
I get....
 
 
    ChildrensBook.java:3: cannot resolve symbol
    symbol  : class Book
    location: class classes.com.wrox.library.ChildrensBook
    public class ChildrensBook extends Book {
                                   ^
    1 error
 
 
 
i have also set my CLASSPATH, under environment variables to ...
 
    C:\Program Files\Jakarta Tomcat 4.0\webapps\begjsp-ch07\WEB-INF\classes
 
 
 
 
please if you gotten to the end of this mail, could you shed some light on my predicament, as i am really beginning to tear my hair out here
 
 
 
cheers
 
 
ewan

thanks for you reply...
 
i feel i may be getting somewhere now that someone has pointed out the things that are right..
 
 
my classes are stored in the webapps folder of tomcat under the directory...
 
webapps\begjsp-ch07\WEB-INF\classes\com\wrox\library\            does this tally with my package declaration?
 
i am unclear as to where the classpath is defined, and what it should contain... (any suggestions?) there will be many more classes within this pakage by the time i have finished this section of the tut.
 
thanks again shivaraj
 
 
cheers

1) Where r u stroing your classes? If u r classes are in com.wrox.library then what r u doing right. But i think u have to check u r classpath and have it pointing to directory which is containing com package.
2) If u just want to use that package, just import that package instead of declaring a package. and com.wrox.library should be in u r classpath.
 
happy coding

thanks very much for you reply, but i think that is what i have done with the declaration...
 
package com.wrox.library;
 
in both of the classes, as i understand it a package is euphanism for directory, would that be correct.
 
as you will gather this is a wrox tut
 
i have pasted the code below for anyone who is interested:
 
initial class:
*******************************************************
package com.wrox.library;
 
public class Book {
 
    private String title;
   
    public String getTitle() {
        return title;
    }
   
    public void setTitle (String title) {
        this.title = title;
    }
   
    /** Creates new Book: Constructor */
    public Book () {
    }
   
    public Book (String title) {
    this.title = title;
    }
 
}
 
*******************************************************
 
 
extension class:
*******************************************************
package com.wrox.library;
 
public class ChildrensBook extends Book {
 
    private int minimumAge;
   
    public int getMinimumAge() {
        return minimumAge;
    }
   
    public void setMinimumAge(int a) {
        minimumAge = a;
    }
   
    public ChildrensBook() {
        super();
    }
   
    public ChildrensBook(String title) {
        super(title);
    }
}
 
*******************************************************
 
once again thanks to anyone who is willing to assist me...

Subject: possible idiot question

i am trying to get my head around class inheritance and have followed some tuts, however....
 
 
having created a simple class, and then creating a subclass, extending the first, i keep getting
 
    Class Book not found in type declaration or import...
 
 
when i try to compile it, they are both sitting in the same package.... pls help!! this is giving me a headache.
 
 
i am currently running Sun's Forte IDE with JDK1.3.1 and serving it up with Tomcat 4.0
 
forte suggests that i have an invalid package declaration but i can find no documentation on how to rectify this, and am baffled as i have followed the tuts to the letter and nothing seems out of kilter.
 
 
any help will be gratefully recieved...
 
cheers..
