Intermitten problem with POST to servlets

Our java application sends a POST method to a servlet, which in turn executes an RMI method to validate a login/password stored in an oracle database. Three times in the last month, users where unable to get their login/password validated.
Checking the access log, I found the log did not have POST records in it, only GETs. Restarting IPlanet would correct the problem.
Need help.

Web Server only logs requests after the response has been sent. Perhaps the Servlet was hanging waiting for a response?

Problems with posting iDocs from MDM in SAP R3

Hi,
I am an MDM consultant, with limited knowledge about SAP R3.
We send material master data from MDM, via PI to R3 using iDocs.
We are having problems with posting MATMAS, and it seems the problems are with updating already existing materials.
In BD87 we get the following warnings:
The field MARA-ERVOE is not ready for input and was therefore not initialized
The field MARA-ERVOL is not ready for input and was therefore not initialized
The field MARA-FERTH is not ready for input and was therefore not initialized
The field MARA-KZGVH is not ready for input and was therefore not initialized
The field MARA-XCHPF is not ready for input and was therefore not initialized
With the last message being:
No changes made
I have checked the MDM syndicator, and none of these idoc-fields are linked to the MDM repository.
So they are syndicated blank.
If we try to resend the material, it is again stopped and in BD87 I see the same messages.
Please help me understanding how to solve these issues.
Thanks,
Thomas

Hi,
Please refer the below threads which talks about the similar problem
http://scn.sap.com/thread/3180116
http://scn.sap.com/thread/1374222
Generally the basic view of the material to be created first. Then the sales, purchasing and other views to be created.
There are few fields in the other views which gets values from the basic data view.

Hi dkpb,
The problem here was that IE9 at the time was incompatible with the forum software. That has since been fixed. What is your issue now? It helps if you describe your specific problem with posting so we can look into it for you.

Problems with post-method in weblogic-server 6.0

Hello,
          I tried to implement a servlet in Visual Cafe working with weblogic 6.0.
          As I used the get-method it worked fine, but as I used the post-method
          I got the following java.lang.IllegalArgumentException:
          bad URLMatchMap path:''
          Does anybody know about this error and where I would have to set the
          path-variable. I have already registered the servlet in web.xml
          Thanx for your help
          Thorsten

Problem with Sessions in Servlets

Hi,
I'm having a problem with sesions with servlets. It seems that if someone logs into my website, which is running on all servlets, while another person is logged on, the second person gets the session of the first person.
I'm using
HttpSession session = request.getSession(true);to get the session in each page. The session contains a user object which shows if the user is logged in and what permissions.
The session should be unique to the client computer right? Or am I jsut screwing this up big time?

Yes, each client will have their own session. However, you may be testing incorrectly:
In Firefox, for example, all instances of the application running on the same machine will share the same cookies, therefore the same session, and would be considered one client.
MS IE will do the same if you use File - New to open a new wondow rather than clicking on the desktop icon.
If the different clients are using different machines and still getting shared data, then you may be using class-level variables in the servlet, which would not be thread safe and could lead to your problems...
public class MyServlet extends HttpServlet {
String data; //bad
int moredata; //bad
public void doGet(...) ... { ... }
}

Problem with logout in servlet After logging out i need to expire the pages

I have a problem in logout using servlet.
I introduced sessions in my page and while logout i used
session.removeAttribute("name");
session.removeAttribute("password");
res.setHeader("Cache-Control","no-store"); //Directs caches not to store the page under any circumstance
     res.setDateHeader("Expires", 0); //Causes the proxy cache to see the page as "stale"
     res.setHeader("Pragma","no-cache"); //HTTP 1.0 backward compatibility
String user=(String)session.getAttribute("name");
          System.out.println(user);
          if(user==null)
               System.out.println("hi");
               req.setAttribute("Error", "Session has ended. Please login.");
               res.sendRedirect("http://localhost:8080/homepage.html");
and after i logout im redirected to login page but after clicking back button im getting back to restricted pages(the pages b4 logout).
what should i do?????

Thanks Dear BalusC,
I tried with this,
rs.getString("DATA_SCAD1")// where the source from .xls files
String pattern = "yyyy-MM-dd";
SimpleDateFormat format = new SimpleDateFormat(pattern);
try {
Date date = format.parse("DATA_SCAD1");
System.out.println(date);
} catch (ParseException e) {
e.printStackTrace();
System.out.println(format.format(new Date()));
this out put gives me Tue Apr 03 00:00:00 IST 2007
But I want to display the date format in yyyy-mm-dd.
regards,

Problem with running multiple servlet in same webapplication with tomcat 3

Hi all,
I am using Tomcat 3.0 as webserver with jdk1.3, Servlet 2.0,
Templates for html file and oracle 8i on UNIX platform.
I have problem with multiple servlet running same webapplication.
There are two servlet used in my application. 1) GenServlet.class
and 2) ServletForPrinting.class
All of my pages go through GenServlet.class which reads some property files
and add header and footer in all pages.
I want reports without header & footer that is not possible through GenServlet in my application.
So I have used another servlet called ServletForPrinting --- just for reading html file.
It is as follow:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ServletForPrinting extends HttpServlet {
public void service (HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
// set content-type header before accessing the Writer
response.setContentType("text/html");
PrintWriter out = response.getWriter();
File f1 = null;
String report = null;
String path = request.getPathInfo();
try{
String p = "/var/home/latif/proj/webapps/WEB-INF/classes" + path;
System.out.println(p);
f1 = new File(p);
p = null;
if (f1.exists()) {
FileReader fr = new FileReader(f1);
BufferedReader br = new BufferedReader(fr);
report = new String();
while ((report = br.readLine()) != null) {
out.println(report);
}catch(Exception e) {
out.close();
report = null;
path = null;
f1 = null;
} // end class
It works fine and display report properly.
But now Problem is that if report is refreshed many times subsequently,
WebServer will not take any new change in any of java file used in web-application.
It works with the previous class only and not with updated one.
Then I need to touch it. As soon as I touch it, webserver will take updated class file.
Anybody has any idea regarding these situation?
Is there any bug in my ServletForPrinting.java ?
Any solution ????? Please suggest me.
Suggestion from all are invited. That will help me a lot.
Thanks in advance

Feel free to delete this topic.
I would strongly suggest at least reading this tutorial to give you an idea of why your fix worked (or maybe only appeared to work). Myself, I never just throw up my hands and say, "Whatever," and wash my hands of the situation without trying my best to understand just what fixed it. Guranteed you'll run into the same/similar problem and this time your fix won't work.
Please do yourself a favor and try to understand why it is working now, and save yourself (or more likely, the next poor dev to work on this project) some heartache.

Travel management - problem with post a trip for an employee in India

Hi,
I am configure travel management for a customer, in there SAP system. I have already made the configuration for countries like Sweden, Finland, Italy, Germany etc, but when I should do it for India I can not save a trip in PR05. I have copied the configuration (schema) from Sweden to India (India has no schema in standard) and that is no problem, but when I should enter a trip and save in PR05 I have the following problem:
1. It seems like I am in US because travelling country is per default USA (it should be India when I have linked the employee to the company code for India in transaction code PO13 and PA40). I can change the country to IN (India).
2. When I enter an expense type and amount, the system have a tax code for USA per default (I have configured that this expense type should choose a tax code in India but the system choose one for USA). I can change it to an Indian tax code.
3. The system also ask for a tax jurisdiction code on the row for expense type. Here I can choose 9999 as a dummy. But I have no idea why I have to specify that. I think that is typical for USA?
4. When I have changed the country to IN, the tax code to an indian tax code and specified the jurisdiction tax code to 9999 and then save I have got the following error message:
" Customization for 1600 j_1iindcus missing in table
Message no. 8I303" and when I have googled on that error message I found that I should go to:
IMG-Logistics General-Tax on Goods movement -India-Basic Settings-Maintain COmpany code settings
but that is according to logistics and everything else in the system as purchase etc is working fine with no problem with tax jurisdiction code so I don´t guess that I should change anything there if I destroy anything else.
5. If I change the country to IN and not register any trip expense but instead register trip segment, that the employee should have compensation for travelling with its own car and then save I have got the message that I have not maintained the currency USD/rupie which is a sign of that the systém beleives that we are in USA.
Please help. I have no idea how to come around this.
Best regards Lisa

Hi again,
In transaction code FITVFELD I have IN as default country but if I change that country to another I still have US as trip country in PR05. In that transaction code (FITVFELD) I have domestic trip, international etc (like configuration in Sweden), but when I initialize a new trip for India I can not change trip type, if there is a domestic or international. When I do the same for Sweden I can choose so I wonder if the system get the information from USA from anywhere else.
I have also read about jurisdiction code and that is special for USA and Canada and then not for India?
Regards Lisa

Problem with post and get (jsp to servlet)

===jsp code(login.jsp)
out.println("<form action='servlet/Login' action='post'>");
out.println("Username <input type='text' name='user' /><br>");
out.println("Password <input type='password' name='pass' /><br>");
out.println("<input type='submit' value='Login' /><br></form>");
the above jsp page is included in another jsp page
===jsp code(index.jsp)
<jsp:include page='login.jsp' flush='true'/>
when submit is clicked in the login form, the data is send (to Login servlet) in the url string, even though i am using "POST" method in the form.
the output of request.getMethod() in the Login servlet gives "GET"
what could be the problem?

The code you've shown us looks fine. The problem isn't in the form code you've listed. Is the form being included inside another form on index.jsp? Does index.jsp have any forms of it's own? Perhaps you aren't submitting the form you think you are submitting. Or, are you redirecting in your serlvet somewhere? Or are you forwarding the request somehow?
I agree with the previous post - we need to see the HTML output that index.jsp results in.

Problems with file uploading servlet, the form action doesnt capture url

Hi, i have one problem. I am working on a project , i have created a servlet that takes uploaded files and processses them and links them back to user to download. The servlet works perfectly from my computer, I am using apache-tomcat-6.0.16 and java 1.6 , I have two forms called encrypt.html and decrypt.html, I will post both of them, now the problem is when somebody access it on the internet while i am running apache, they get a connection was reset on a firefox browser and same stuff on Internet Explorer.
i have checked my server logs and saw nothing unusual there, So please if you can help me, it is my project.
I am pasting html file and error message that other users where getting remotely.
<html>
<head>

<link rel='STYLESHEET' type='text/css' href='encrypt.css'>
</head>
<body>
<center>
<form name='encrypt' enctype='multipart/form-data' method='POST' action='http://localhost:8080/examples/temp2

Hi, thank you for your replies, I found out few things about my servlet, and its portability
and i have few questions, although i marked this topic as answered i guess its ok to post
I am using javax.servlet.context.tempdir to store my files in that servletcontext temporary directory. But i dont know how to give hyperlink
of the modified files to the user for them to download the modified files.
What i am using to get the tempdir i will paste
File baseurl = (File)this.getServletContext().getAttribute("javax.servlet.context.tempdir");
System.out.println(baseurl);
baseurl = new File(baseurl.getAbsolutePath()+File.separator+"temp"+File.separator+"files");
baseurl.mkdirs();so i am storing my files in that temp/files folder and the servlet processes them and modifies them, then how to present them as
links to the user for download ?
and as the servlet is multithreaded by nature, if my servlet gets 2 different requests with same file names, i guess one of them will be overwritten
And i want to create unique directory for each request made to the servlet , so file names dont clash.
one another thing is that i want my servlet to be executed by my <form action> only, I dont want the user to simply type url and trigger the servlet
Reply A.S.A.P. please..
Thanks and regards,
Mihir Pandya

Problem with posting comments of a specific picture

So I have been able to post the comment in the page I am creating and that comment is also saved in the comment table in the database with the id of the picture but when i am in the first picture and I comment the comments are posted saved in the database with the id 1 and then i go to the second the comments are also posted and saved in the tabel comment with the id of the picture 2. But my problem is that when i go to the second picture i can also see the comments of the first picture. So in all of my pictures I can see comments of pictures with other id. How can i manage to solve this problem. Please suggest me sth
I'll describe a little bit my database
name of database is art
picture tabel I have named piktur(id_piktur,Titulli,Pershkrimi,Piktur_url) rsGallery is picture recordset
the comment tabel I have named komente(id_koment,id_piktur,Tekst)rsKomente is comment recordset
Tekst is the column where the comment is save
I'm using the session variable so i can get the id of the picture from the picture table and insert it in id picture column of the comment tabel
this is the piece of code i guess i should make some conditions but i have tried sth myself but I have not managed to solve my problem. The pictures in my page are organised with paging and repeat region only showing 1 picture at a time. the comment are also repeat region showing all the comments at a time.
<p>
      <?php while ($row_rsKomente = mysql_fetch_assoc($rsKomente)) { ?>
        <?php
$id_piktur=$row_rsGallery['Id_piktur']; $_SESSION['id_piktur']=$id_piktur;
          echo $row_rsKomente['Tekst']."<br/>" ;?>
        <?php } ?>

>thnx yeah i fixed the problem this time i understood you.
Glad you got it working.
>you confused me the first time with the explanation because you mentioned loops
Yeah. Normally with a repeating region you would need to use nested loops; an outer loop for the picture and an inner loop for the related comments. During each iteration of the outer loop you would execute the sql to retrieve the inner loop recordset. However, since you are using paging with only one recordset per page, the comment recordset SQL does not have to execute inside the picture loop. Hope that makes sense.

Problems with exec() in Servlet

Hi All,
In my project i have used exec()in servlets to get the ouput from the c- program.I am using linux 8.0 and the server is tomcat-4.1.24.so that i try this following code:-
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ServletExecute extends HttpServlet
public void doGet(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException
String[] command={"/bin/csh","-c","home/anand/Ananth/grpmaschk.run sptest S"};/*Here the grpmaschk.run is a c-program which genarates an output that is passed to sptest as parameter and S is a argument which indicates the action is done from Servlet*/
res.setContentType("text/plain");
PrintWriter out=res.getWriter();
Process p=null;
Runtime rt=Runtime.getRuntime();
try
p=rt.exec(command);//Executing the action on command string
catch(Exception e)
out.println("The Error Message is:"+e.getMessage());
try
FileInputStream fin=new FileInputStream("/home/Ananth/sptest");/*
Once the output is generated from the c-program it will be stored in the sptest in /home/Ananth */
BufferedReader br =new BufferedReader(new InputStreamReader(fin));
String line=null;
while((line=br.readLine())!=null)
out.println(line); //From there i am reading the contents in it to be displayed in the browser
} catch(Exception e1)
out.println("The error message was:"+e1.getMessage());
Whren it is displayed in the browser i am getting an error
/home/Ananth/sptest not found which means that exec() is not working (or)executing.What is the problem here ???Plz. do provide a solution for this.It is quite Urgent.I will be waiting for ur replies.
Thanx,

Hi sir,
Sorry for the mistake i did there but by using /home/....
also the output is not coming.
Here is the code again for ur reference:-
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ServletExecute extends HttpServlet
public void doGet(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException
String[] command={"/bin/csh","-c","/home/anand/Ananth/grpmaschk.run","home/anand/Ananth/sptest S"};//corrected one
res.setContentType("text/plain");
PrintWriter out=res.getWriter();
Process p=null;
Runtime rt=Runtime.getRuntime();
try
p=rt.exec(command);
catch(Exception e)
out.println("The Error Message is:"+e.getMessage());
try
FileInputStream fin=new FileInputStream("/home/anand/Ananth/sptest");
BufferedReader br =new BufferedReader(new InputStreamReader(fin));
String line=null;
while((line=br.readLine())!=null)
out.println(line);
} catch(Exception e1)
out.println("The error message was:"+e1.getMessage());
Here exec(....) is going through but the path in FileInputStream is showing an error.The error message i got when i run it in the browser is :-
The error message was:/home/anand/Ananth/sptest (No such file or directory).Which means exec() function itself is not executed???. Is there any thing to do with security reasons or anything u need to configure in the tomcat configuration file??? Where i found that
when i give /home/anand/Ananth/grpmaschk.run only in the exec() then the output is diaplyed in the browser.So i think exec() is workuing well but not with this huge argument
String[] command={"/bin/csh","-c","/home/anand/Ananth/grpmaschk.run","home/anand/Ananth/sptest S"};
Pls. do provide a solution for this problem.I will be waiting for ur replies.....
Thanx,
m.ananthu

Problem with my applet-servlet comunication

Hello:
I'm using a dynamic chart on my applet, which gets the data from a servlet, by URLConnection. These service work, but after a moment, the chart scroll is stopped and I get the next error on java console:

The applet make request to servlet by URLConection permanently, which gets
the data from SQL Server.
I'm using JVM 1.5.
The applet makes requests to servlet by normally url, not access to local resources (or file system).
Please can anyone help me?

http://java.sun.com/j2se/1.5.0/docs/api/java/net/ProxySelector.html
Selects the proxy server to use, if any, when connecting to the network resource
referenced by a URL. A proxy selector is a concrete sub-class of this class and is
registered by invoking the setDefault method. The currently registered proxy selector
can be retrieved by calling getDefault method.
The getDefault Throws:
SecurityException - If a security manager has been installed and it denies
NetPermission("setProxySelector")
http://java.sun.com/j2se/1.5.0/docs/api/java/net/NetPermission.html
getProxySelector
The ability to get the proxy selector used to make decisions on which proxies
to use when making network connections.
Malicious code can get a ProxySelector to discover proxy hosts and ports on
internal networks, which could then become targets for attack.
I checked my java.policy for my w2k jre 1.5 installation but could not find any specific
NetPermission in there. I never had this problem using URL and URLConnections
in 1.5 but it sounds strange that creating an URL in an applet could throw a
SecurityException with the default jre 1.5 installation (both objects are introduced
since 1.5).
If you are using windows could you open the java control panel and select "use
browser settings" in the General tab after clicking the "Network settings" button?
I have this option in my jre settings and never got that Exception.
