'Error: 500 SC_INTERNAL_SERVER_ERROR' after init() and before doGet() method in servlet.

Hi to you all,
I have been working with ias6.0 sp2 on Unix.
I have a simple web application with servlets and packaged auxiliary classes. Deployment seems all good. But when I try to call my first servlet with URL, I get this message on the navigator : "Error: 500 SC_INTERNAL_SERVER_ERROR
null ".
In the log file, I have that :
"error: Exception: SERVLET-execution_failed: Error in executing servlet myServlet: java.lang.NullPointerException [...]
at com.netscape.server.servlet.servletrunner.ServletInfo.checkAuthorization (Unknown source)
error: APPLOGIC-caught_exception: Caught Exception:
java.lang.NullPointerException
at com.netscape.server.servlet.servletrunner.ServletInfo.popPrincipalFromTLD (Unknown source )
My application works well with iws. So, what's up ?
The init() method is executed, but not the doGet() one.
Well, hear you soon !

Hi,
Although it is difficult to point out the place where the error exactly occurs, I can suggest the reasons. The possible place for error to occur normally lies in the database connectivity. When the HttpServlet is not able to communicate with the database or encountered errors while communicating with the database. Please let me know if this helps.

Raj

  • Why does the Error: 500 SC_INTERNAL_SERVER_ERROR appear when multiple users access my JSPs but does not occur when only one user accesses my JSPs?

    When multiple users run my JSP application, why do some users get an Error: 500 SC_INTERNAL_SERVER_ERROR for certain JSP pages with the error message No such file or directory. The JSP listed on the Error 500 page varies and is not always the same. When only one user runs my JSP application, the problem does not occur?
    The database connection is held when the user logs in or accesses certain parts of the JSP and then is immediately released. No connections to the database are held.

    It sounds like you might having some kind of thread safety issue with your code. Either that or your guess about running out of database connections.

  • After Range and Before Range

    Hi Experts,
    I encounter a problem with my templates that use After RANGE or BEFORE RANGE.
    In Planning Application, there is no problem downloading the file that uses AFTER RANGE and BEFORE RANGE but in CONSOLIDATION Application I was unable to download or open the file with AFTER RANGE and BEFORE Range.
    When I tried to open it, the Excel Program Hangs or Not Responding, then I must End Process to use the Microsoft Excel again.
    Any suggestions?
    thanks

    Why don't you just put contents of ds_remote_schema.ldif from the IS6.0 install packages to your schema file, any ##name you want and tell installer to use preconfigured directory?! Up to IS6.0ea2 schema was a separate file.

  • Freight after ED and before VAT, Discount after ED and before VAT

    Hi,
    We have below two scenario and we want to map this.
    1) Discount after ED and Before VAT
    2) Freight After ED and Before VAT.
    first requirement will be fullfilled by assigning subtotal '6' to discount condition in M/08 and 362 routine to BASB and 363 routine to VAT condition in OBQ3
    Second requirement will be fullfilled by assigning subtotal '6' to Frieght condition in M/08 and assigning 363 routine to VAT condition in OBQ3 and removing 362 routine against of BASB.
    We want to map it both pl. guide us how to map BASB value in TAXINN.
    Regards,
    Rajesh

    Hi Ajit,
    Appreciate your answer.
    Taking you answer into consideration i have below excersice. 
    Subtotal '6' to Freight and Discount conditions
    362 routine to BASB conditon type in OBQ3
    363 routine to VAT condition in OBQ3
    it will work perfect in case of Discount after ED before VAT. but in case of Freight after ED bfroe VAT its not working.
    Since 362 routine, will do minus '6' subtotal value and plus '4' vlaue.
    If we add freight component to condition then system will reduce amount from BASB. that is practicly we dont wan't.
    expected your comment.

  • Who calls doget() method of servlet

    hello all,
    i have typical customized webserver.
    the problem i have with that is when i configure it with IP address and when i send a request through browser using HOST NAME ,its not recognizing.
    the same happens vice versa
    that is : set up host name in the http server, and when try a request through IP Address using a web browser.
    can any body clear me who calls the doGet() method of servlet. if it is USER AGENT of web browser, is there any operation executes between
    USER AGENT - DoGet() method of servlet?
    regards

    The servlet is on the server, the browser is on the client, so, do it think it possible (unless the browser is written in Java and does it's browsing with RMI, which is patently absurd) that the browser call doGet()?
    It is rather obvious, that the browser sends an HTTP request to the Application Container (or a web server such as apache which then uses some module to communicate with the Application Container, but the end effect is the same), and that Application Container calls the doGet() method.
    Edit: And man am I slow and "wordy".

  • FREIGHT AFTER ED AND BEFORE TAX (CST/VAT)

    Hi Friends,
    We need the freight to be calculated after Excise duty and before Tax ( CST/VAT). For example
    Basic Value = 100
    ED 10% = 10
    ECS 2% = .2
    SECS 1% = .1
    10.3
    Freight = 10
    120.3
    CST 3% = 3.60
    Total Value = 123.90
    In our case Freight is calculation after TAX. But we need to calculation of CST/VAT includes freight.
    Kindly suggest how to make changes in pricing procedure.
    I created one condition in pricing procedure for freight, but the same is not transferring to tax procedure for calculation. I also created one condition in tax procedure. But value is not passing to tax procedure.
    Knidly give the solution at the earliest.
    Regards,
    Shital Deshpande

    Check in tax procedure(OBQ3) whether freight condition(Z*) is included after ed subtotal ?
    Whether you maintained condition record(FV11) for lumpsum Z* freight condition ?

  • Full upload after INIT and Delta

    Hi Experts,
    a quick question - If there is INIT and Delta infopackage running  and I do another infopackage with full update option, will there be any issue in Delta?
    when do I need to run repair? only when there is possibility of duplicate loading?
    Thanks - SM

    Thanks Srini/Vikram for your respone.
    when there is deltas already running for the datasource , you can't request for Full but you can request using 'Repair full' which will acts and extract data as full load and it won't disturb present delta's
    >>. Thanks Srini. thats bottom line... after delta, you need to run repair full not full. and repair full will also pull data from setup table (history). I was thinking repair full is for taking care of duplicate, but dups we need to remove manually.
    where is repair full option in IP?
    where I can see all INIT conditions for a infopackage? for example INIT was done 3-4 times.. year 2001-2002, 2002-2003 etc, so all these INIT crit should be stored somewhere?

  • Discount after Excise And Before VAT

    Dear All,
    We have the below requirement, Vendor is giving the discount After Taxes & before calculating the VAT. How to meet this requirement ?
    Right now i have created a condn type & added in tax procedure, But not able to meet the requirement.
    We are using TAXINN tax procedure.
    Ex : Base Price is Rs 100
           BED       Rs 8
           ECess    Rs 1.60 
           SECess  Rs 0.80
    Total Inc Taxes is 110.40
    Then we need discount Say Rs 2/Ltr
    Value After Disc is Rs 108.40
    VAT(12.5%)   Rs 13.55
    Actual PO Value Rs 121.95
    B/regds,
    CB

    Hi,
    I think you can make a condition type and add this condition type in your pricing procedure below the step of Excise duties. After this condition step, then put the Sales tax conditions to calculate on this step.
    Ex: 10   Base Price
          20   Excise Duty
          30   Cess
          40   ECess
          50   Total Amount Incl of Duties
          60   Discount on this Total Amt Incl Duties
          70   Total Amount Incl of Duties and Disc (Step 50 to 60)
          70   Sales Tax ( from Step 70 )
    Hope this clears u r doubt.
    Regards

  • Difference between cash value after customs and before customs?

    Hello experts.
    Where can you percieved the diffrerence on the landed costs if you select the allocation by before/after customs?
    Looking forward to your reply,
    Kind regards

    Hi Erickson,
    In the landed cost you can allocate your customs cost. Customs cost allocation to items can be difference per item customs cost percentage (as defined in the master data) or based on total cost allocation (actual customs in the landed cost screen).
    If your landed cost allocated to total value after custom, then that cost will be allocated based on item value after customs (item cost + customs).
    Example:
    1. Item A; Value 500; customs rate : 10%
    2. Item B; Value 1500; customs rate: 15%
    Total landed cost 2000
    Landed Cost Allocation:
    => cash value before customs:
    1. Item A
         => Customs = 10% * 500 = 50
         => Landed cost = (500/2000) * 2000 = 500
         => final cost Item A = (item cost + customs + landed cost) = 500 + 50 + 500 = 1050
    2. Item B
         => Customs = 15% * 1500 = 225
         => Landed cost = (1500/2000) * 2000 = 1500
         => final cost Item A = (item cost + customs + landed cost) = 1500 + 225 + 1500 = 3225
    => cash value before customs:
    1. Item A
         => Customs = 10% * 1000 = 100
         => Cash value after Customs = 500 + 100 = 600
         => Landed cost = (600/2275) * 2000 = 483.52
         => final cost Item A = (item cost + customs + landed cost) = 500 + 100 + 483.52 = 1033.52
    2. Item B
         => Customs = 15% * 1500 = 225
         => Cash value after Customs = 1500 + 225 = 1725
         => Landed cost = (1725/2275) * 2000 = 1516.48
         => final cost Item A = (item cost + customs + landed cost) = 1500 + 225 + 1516.48 = 3241.48
    => If actual customs directly being input into landed cost screen, the would be no difference on the landed cost allocation since all customs allocated proportionally.
    Cheers

  • Is it possible to draw on a picture after loading and before displaying it?

    Hi to all :)
    I intend to write a small applet(connected with a server using RMI, but that's not important :) ) that represents the 'tic-tac-toe' game.
    I've planned to create 3 pictures - blank, containing a circle and containing a cross.
    Then I think to used 9 JButton-s and set the blank pic as an Icon for the JButton. An action event listener will change the picture to circle ot cross and so on...
    I would like to draw a line over the 3 pictures for the winner at the end of the game.
    Is it possible to load a circle or cross picture, then draw a horizontal/vertical/diagonal line on it at runtime and after that set it as an Icon for the Jbutton ?
    Thanks in advance. Take care :)

    To my knowledge, you can't overlay icons on a JButton without subclassing it and overriding paintComponent. In that case, II suppose you could try painting over all your buttons with something like:parentContainer = new JPanel() {
        @Override
        protected void paintComponent(Graphics g) {
            super.paintComponent(g);
            drawLine(0, 0, 100, 100); //etc...
    parentContainer.add(myFirstButton);
    //etc.

  • In insert: Space after period and before carriage return is being ignored

    I am using Oracle 11.2.0.2.
    let say I create table temp(a varchar2(20);
    insert into temp values ('value.
    valuue2');
    I have put space after 'value. ' but it is being ignore when I run it from linux host in sqlplus.
    The space seems to be preserved when I insert it from TOAD/Windows xp.
    Any idea what might be causing it.

    hI,
    I have the same result in SQLPLUS.
    I would not rely on code with strings spread over multiple lines you should use the below code to add newlines:
    insert into temp values ('Yes.Space. ' || chr(10) || 'x');This makes it very clear there is and a space and a newline.

  • Question on Deltas after Init and Full load

    Hi
    We have an ODS X pushing data to two cubes A & B. ODS X data is initialized to Cube A long back and deltas are loading every day. Now We have recently created Cube B and made a fulll load from ODS X and loading the Deltas from ODS X with same info package we are using to load the deltas in to cube A. Do we get any data inconsistencies if we load like this ? Do I need to make a new init for Cube B to get proper deltas ? I'm hoping that Deltas will automatically take care of reversal in Cube B too...Please advice.
    Thanks
    Sam

    This looks fine, since u have already done full load from X to B, and currently loading delta to both A n B , it is fine, no need for new init.
