Illegal State Exception with response.sendRedirect

Hi all,
When i am using response.sendRedirect(address), It is giving illegal state exception at few places. At few places it is working fine. I couldnt trace the reason.
I am using tomcat 4.1 with SSL configured for the server. Will session tracking effect response.sendRedirect(address)'s ability any way?
Can any body help me out...
Thanks in advance...

I believe this quite often occurs when you have tried to send some kind of response already. I.E. you should not have sent anything to the client when you call this method so start by looking for any write's you have prior to the sendRedirect().

Illegal State Exception in JSP login

I had a working log in/check password systems for a low security application. User types in username and password and this is sent to the checkpassword.jsp. Using Server variables I counted the number of attempts and if it was more than three, they were not allowed to try again that session. When I moved this page to newer version of Tomcat running in Apache rather than over IIS, my simple counting function no longer works and I can't for the life of me understand why I'm getting an Illegal State Exception with the following code:
java.sql.ResultSet RS=statement.executeQuery("Select WUUSER, WUPWD FROM WEBUSER WHERE WUUSER='"+ (request.getParameter("username").toUpperCase()) + "' AND WUPWD= '" + (request.getParameter("password")) +"'");
HttpSession ViewProtectedPage = request.getSession(true);
HttpSession UserSession = request.getSession(true);
if (RS.next())
ViewProtectedPage.putValue("password","correct");
//HttpSession UserSession = request.getSession(true);
//allows username to be entered in upper or lower case
UserSession.putValue("username",(request.getParameter("username")).toUpperCase());
response.sendRedirect("tracking.jsp");
else
ViewProtectedPage.putValue("password","false");
if (ViewProtectedPage.getValue("trycount")==null) {
ViewProtectedPage.putValue("trycount","1");
response.sendRedirect("loadtrackbadlogin.html");
if (ViewProtectedPage.getValue("trycount")=="1") {
ViewProtectedPage.putValue("trycount","2");
response.sendRedirect("loadtrackbadlogin.html");
if (ViewProtectedPage.getValue("trycount")=="2") {
ViewProtectedPage.putValue("trycount","3");
response.sendRedirect("loadtrackbadlogin.html");
if (ViewProtectedPage.getValue("trycount")=="3") {
response.sendRedirect("noentry.html");
RS.close();
It works fine if the user uses the proper username and password but crashes on me if they use the wrong info. I think it has something to do with my initialization of the user variables.

I don't know that this is the root cause of your problem, but it certainly could be. When comparing two strings, you need to use the .equals() method, not ==.
(except in the null case, where checking for null with == is perfectly okay).
if (ViewProtectedPage.getValue("trycount").equals("1")
..etc
Some other notes... use if/else if/else rather than a whole bunch of ifs, since all your statements are mutually exclusive. Maybe even put those lower ifs inside your outer "else" since you're obviously not going to reach them after a sendRedirect(). On that same note, place a return; after the sendRedirect() to state that the rest of the page need not be loaded/executed.

Illegal state exception in filters can any help me plzzzzzzz

JComboBox Illegal state Exception problem

Hello Everyone,
I have the following code for creating a combobx in Eclipse. Now whenever eclipse reloads it gives an Illegal state exception error. When I remove the code and rewrite the same code it works fine. Any idea on how to fix this problem??
Things are normal and there is no problem when I dont initialize the combobox.
private JComboBox getJComboBoxNumOfSteps() {
       if (jComboBoxNumOfSteps == null) {
     String[] valStrings = { "1", "2", "3", "4", "5", "6", "7", "8", "9" ,"10","11","12","13","14","15","16","17"};
     jComboBoxNumOfSteps = new JComboBox(valStrings);
     jComboBoxNumOfSteps.setPreferredSize(new java.awt.Dimension(80,25));
     jComboBoxNumOfSteps.addActionListener(new java.awt.event.ActionListener() {
     public void actionPerformed(java.awt.event.ActionEvent e) {
                                          Integer i = new Integer(jComboBoxNumOfSteps.getSelectedIndex()+1);
                          jTextArea.append(i.toString());
          jTextArea.append("\n");
        return jComboBoxNumOfSteps;
}Thanx Amar

Depends what context, and who's exception....
I'll go with my best guess here though.
You're using wait() and notify() and or notifyAll() with some threads. In this case the IllegalStateException is being thrown because you are calling one of these methods on an object you are not holding the lock for. Here are some good resources.

if not,.... oh well, describe your problem better.

Please clarify on Illegal state exception

Dear All pl explain Illegal state exception occurs in some program why. and what is the solution.

Hi,
This exception is thrown when a method is invoked at an illegal or inappropriate time or if the provider is not in an appropriate state for the requested operation.
In servlets, for example, you have a method forward() in the RequestDispatcher class, which forwards the request to another resource for processing. This method should be called before the response is committed, else it throws IllegalStateException.

Strange behaviour with response.sendRedirect

I have a strange problem with response.sendRedirect

Hi,
response.sendRedirect() may throw an IOException if URL not found.So you have to write throws or try & catch.

Illegal State Exception ; Resource resolver already closed

Hi
In my component I have a page resource. When I am trying to get the image resource of the same as below it is throwing me an Illegal State exception
Resource resource = page.getContentResource("image");
My error stack trace is as follows
Eventhough i am not closing any resource ; it is giving me illegal state exception for the resource. Please help me in finding a solution for this.
Thanks
Veena

Are you calling the right path?
The call to page.getContentResource("image") will end up calling the following:
resource.getResourceResolver().getResource(resource, “jcr:content/image”);

Weblogic 6.0 (SP2) generates incorrect java code for JSP with response.sendRedirect()

          Hi,
          Here are the steps to reproduce the problem with the examplesWebApp application
          bundled with wlserver6.0(sp2):
          Product: Weblogic server 6.0 (sp2)
          Browser: IE 5.0
          1. Add index.jsp as the welcome file in WEB-INF/web.xml
          2. Create index.jsp as below:
          <%
          response.sendRedirect("index.html");
          return;
          %>
          <html>
          <head>
          <title>Index JSP file</title>
          </head>
          <body>
          <font color="red">This is index.jsp file </font>
          </body>
          </html>
          3. Create index.html as below:
          <html>
          <head>
          <title>Index HTML file</title>
          </head>
          <body>
          <font color="red">This is index.html file </font>
          </body>
          </html>
          4. Run the examples server and make sure examplesWebApp is deployed on the examples
          server using the console
          5. Access the URL http://localhost:7001/examplesWebApp
          The page will display a compilation error as below:
          C:\bea\wlserver6.0\config\examples\applications\examplesWebApp\WEB-INF\_tmp_war_examplesServer_examplesServer_examplesWebApp\jsp_servlet\_index.java:89:
          unreachable statement
          out.print("\r\n<html>\r\n<head>\r\n<title>Simple html</title>\r\n</head>\r\n<body>\r\n<font
          color=\"red\">This is index.jsp page</font>\r\n</body>\r\n</html>\r\n");
          ^
          and a look at the generated java code for index.jsp (_index.java) will reveal
          the erroneous code snippet below in the jsp service method:
          try { // error page try block
          //[ /index.jsp; Line: 1]
          response.sendRedirect("index.html"); //[ /index.jsp; Line: 2]
          return; //[ /index.jsp; Line: 3]
          out.print("\r\n<html>\r\n<head>\r\n<title>Simple html</title>\r\n</head>\r\n<body>\r\n<font
          color=\"red\">This is index.jsp page</font>\r\n</body>\r\n</html>\r\n");
          } catch (Exception __ee) {
          while (out != null && out != _originalOut) out = pageContext.popBody();
          pageContext.handlePageException(__ee);
          The above web application works fine in Tomcat 3.2.X environment. The Weblogic
          server 6.0 servlet engine should not generate the "out.println()" corresponding
          to the html section of index.jsp. The moment it sees the "return", it should stop
          processing further.
          Can someone from Weblogic support team please verify this and let me know when
          this bug will be fixed?
          One interesting thing I noticed was when we last tried weblogic 6.0 at its beta
          stage, it worked fine after we put in a special patch jar file called "redirectfix.jar"
          we received from weblogic team but somehow it got re-introduced by the time it
          was released!!
          We are planning to migrate our product from tomcat 3.2.x to weblogic 6.0. Our
          product has a lot of pages with such conditional {response.sendRdirect("page.jsp");return;}
          blocks. We would really appreciate a faster response form weblogic team.
          Thanks in advance.

Why should it stop when it sees a return? Is that in the spec?

TABLE ILLEGAL STATEMENT error with MODIFY command

Hi gurus,
i want you to inform me about table illegal statement error. The error occurs when i use modify as below.
loop at itab.
   select .......
         where xxx eq itab-xxxx.
       MODIFY itab.
endselect.
endloop.
i know that i have to give the sy-tabix as INDEX parameter to the modify command. but i want to know why i have to do this?
cause when i debug, i follow the sy-tabix field and it have not a change in select endselect.
may the reason of the error about cursor in select and cursor effects modify command?
or why?
Thx,

Hello,
I guess this is because your MODIFY statement is inside the SELECT ... ENDSELECT & not inside the LOOP ... ENDLOOP.
SAP documentation says:
Within a LOOP loop, the INDEX addition can be ommitted. In this case the current table line of the LOOP loop is changed.
You have to change the coding:
DATA: v_index TYPE i.
loop at itab.
v_index = sy-index.
select .......
where xxx eq itab-xxxx.
MODIFY itab INDEX v_index.
endselect.
endloop.
BR,
Suhas
PS: The coding practice followed is not very performance oriented as well. May be you should have a look around in some blogs, wikis in SCN & change the code accordingly.

Strange Illegal State Exception

Hello all,
I've been writing a large webapp for a while and have suddenly started getting this exception. It turns up in the web server logs, occurs in the middle of a loop, and although all exceptions in my servlet are caught and forwarded to a generic error page, this exception causes the output to stop - leaving just the already-output HTML on the page. I guess this is because it's a runtime exception.
I know this can occur by calling getWriter() and getOutputStream() in the same servlet, but I've done nothing except println() on my PrintWriter after using getWriter() to retrieve it.
Anyone got any ideas on why this might occur?
Thanks!
Gemma

Here's the loop in which the error occurs:
           for(int i=0;i<theVector.size();i++)
          CustomObject temp = (CustomObject)theVector.elementAt(i);
          if(user.hasMultipleAttributes())
            if(i==0)
              out.println("<tr><td colspan=\"6\">For <b>" + temp.getCountry() + "</b></td></tr><tr><td colspan=\"6\"><br></td></tr>");
            else
              if(!temp.getCountry().equals(lastCountry))
                out.println("<tr><td colspan=\"6\">For <b>" + temp.getCountry() + "</b></td></tr><tr><td colspan=\"6\"><br></td></tr>");
            lastCountry = temp.getCountry();
          out.println("<tr><td>" + temp.getStory() + "</td>");
          out.println("<td>" + temp.getLanguage() + "</td>");
          if(currentUser.hasMultipleAttributes())
            out.println("<td>" + temp.getCountry() + "</td>");
          out.println("<td>" + temp.getRequestDate() + "</td>");
          out.println("<td>" + temp.getPublishDate() + "</td>");
          if(temp.isComplete())
            out.println("<td><img src=\"" + URLContainer.getTickImageURL() + "\"></img></td>");
          else
            out.println("<td><form method=\"post\" action=\"" + URLContainer.getCompleteStoryDetailsURL() + "\"><input type=\"hidden\" name=\"storyname\" value=\"" + temp.getStoryName() + "\"><input type=\"hidden\" name=\"language\" value=\"" + temp.getLanguage() + "\"><input type=\"hidden\" name=\"country\" value=\"" + temp.getCountry() + "\"><input type=\"submit\" value=\"Complete Usage Details\"></form></td>");
          out.println("</tr>");
          CustomObject temp2 = (CustomObject)theVector.elementAt(i+1);
          if(!lastCountry.equals(temp2.getCountry()))
            out.println("<tr><td colspan=\"6\"><br></td></tr>");
           } I can't see anything in here which would cause such an error. I don't pass the PrintWriter (out) anywhere... I don't set the buffer size and I don't believe that the PrintWriter is returned in autoFlush mode (not 100% sure though).
For redirects, I tend to use HttpServletResponse.sendRedirect().
Thanks
Gemma

How to avoid illegal state exception in jsp/servlets

Hi,
Am working on jsps and servlets ,some times am getting Illegalstateexception,in what situations we will get this exception,can any one tell clearly about this exception..
mani

Since there's no other real supporting information you have out there, I can only take a wild stab at this...
My guess is that you're trying to invoke methods on the server with your jsp code that isn't allowed. For example, I often work with a PDM software that will throw Illegalstateexceptions when I try to modify objects in the system that are not checked out. More than a java thing, this might be an issue with the servlets you're using. If your servlet is being provided by a vendor, you might want to check up on their API for more information about such an error occuring, or consult their technical support, if such a group exists.
If this is your own servlet, I would suggest making sure that the methods you're trying to invoke are available for the servlet to invoke, which would also cause that exception.

Illegal state exception

I am often getting the exception shown below

How to avoid Illegal State Exception?

Im using struts and develop in J2EE. My action class calls the ejb and returns to the actionClass and then to the jsp. This works once and the second time , i get IllegalStateException. But without recompiling when i restart ,my jboss and preform the previous activity , it works fine!!
Does have an explanation and provide a solution?
Thanks
