A little problem with session

How can i put a session variable in a string variable??
I tried this but
Note: sun.tools.javac.Main has been deprecated.
/respostaGaleria.jsp:92: Incompatible type for =. Explicit cast needed
to convert java.lang.Object to java.lang.String.
arquivo=session.getAttribute("filename");
^
1 error, 1 warning
arquivo is a String variable

Note: sun.tools.javac.Main has been deprecated.
/respostaGaleria.jsp:92: Incompatible type for =.
Explicit cast needed
to convert java.lang.Object to java.lang.String.
arquivo=session.getAttribute("filename");
^Well, as long as "filename" is a String
arquivo=(String)session.getAttribute("filename");

Problem with sessions in Kate Editor

Hey guys!
I'm using Kate Editor to code and i'm having problems with sessions. If kate is open and I logout KDE, when I come back to KDE all my customizations in Kate's session (activated plugins, font size, etc) are lost.
If I manually close Kate before logout from KDE, all the customizations are kept when a manually start Kate. I tried a lot of workarounds, but none worked.
Is this a bug? Someone else with this issue?
Thanks in advance!

The Warning errors are simply because you don't have the tablespaces, users, and roles defined in your application system under the DB Admin tab. Unless it is important to you to capture the physical implementation of your tables exactly as well as the table definitions, you can safely ignore these. If the physical implementation IS important to you, then you need to create these tablespaces, roles and users under the database that you created under the DB Admin tab before you start the capture.
The Error is because in the set of objects you are capturing there is a foreign key that references the table named "PLEASANT". This table must be among the objects that you are capturing, or must already be in a Table Definition in your application system in the repository.

Problem with Sessions in JSP

Hi,
I am working on a JSP based website, where I am facing problem with sessions. The user is asked to login by providing her id and password. If found correct, a bean is created and populated with all her details and placed in session scope. I plan to use the information stored in the bean on other related pages until she logs out.
<jsp:useBean id="validUser" scope="session" class="UserBean" >
<c:set target="${validUser}" property="userId" value="${fn:trim(dbValues.UserId)}" />
<c:set target="${validUser}" property="userName" value="${fn:trim(dbValues.UserName)}" />
</jsp:useBean>
<c:redirect url="userHome.jsp" /> The user is presented her homepage - 'userHome.jsp', where she can find various links, like 'Update Profile', 'Pay Registration Fees', 'Book Room' etc. The information stored in the bean is available on 'userHome.jsp'page.
<A HREF='userHome.jsp'>Home</A>
<A HREF='editPersonal.jsp'>Update Profile</A>
<A HREF='registrationFee.jsp'>Pay Registration Fees</A>
<A HREF='bookRoom.jsp'>Book Room</A>
<A HREF='logout.jsp'>Logout</A> The problems are:
1. Whenever user clicks on any of the above mentioned links and moves to any page, the bean comes out as null.
<%-- Verify that the user is logged in --%>
<c:if test="${validUser == null}">
<jsp:forward page="loginForm.jsp">
<jsp:param name="origURL" value="${pageContext.request.requestURL}" />
<jsp:param name="errorMsg" value="You must be logged in to access this site." />
</jsp:forward>
</c:if> 2. The URL shows an additional jsessionid, which my client doesn't want to see.
3. On every click on any link, the value of this jsessionid changes.
What I presume, when I am clicking on different links, my session changes, and so I am seeing a different jsessionid. And since session is changing, therefore the bean is not available in a different session.
All this works fine with localhost, problem comes into picture, when I upload my pages to the server.
Puzzled, can anyone help, where am I going wrong? Let me add here, I am new to JSP and hence don't have much resources with me.

There are several ways sessions can be exchanged between the browser and the server in a j2ee web application.
1. The default is through cookies. However when the client does not accept cookies, the server appends the session id to the url.
2. Some servers also facilitate session information exchange using session id in the url even if the client does accept cookies. This is usually ahieved through a setting in some server configuration file.
You will have to find out why the server in your application is appending the session id to the url.
Whatever be the case, the server should be able to look up the session from the incoming request (be it from the session id in the url or a session cookie).
When session information is exchanged through the JSESSIONID in the url, you should ensure that each and every url that goes to the server has this input parameter. To do that all links and form post urls in your servlet/jsp should be treated with a call to encodeURL().
For example, in a jsp
   <a href = "<%=response.encodeURL("/nextJsp.jsp")%>">Click here </a>
or
   <form action = "<%=response.encodeURL("/nextJsp.jsp")%>">
   </form>etc.

Little problem with Strings.

          I have an little problem with Strings, i make one comparision like this.
          String nombre="Javier";
          if( nombre.equalsIgnoreCase(output.getStringValue("CN_NOMBRESf",null)) )
          Wich output.getStringValue("CN_NOMBRESf",null) is "Javier" too, because I display
          this before and are equals.
          What I do wrong?.


You are actually making your users key in things like
"\026"? Not very user-friendly, I would say. But
assuming that is the best way for you to get your
input, or if it's just you doing the input, the way to
change that 4-character string into the single
character that Java represents by '\026', you would
use a bit of code like this:char encoded =
(char)Integer.parseInt(substring(inputString, 1),
16);
DrClap has the right idea, except '\026' is octal, not hex. So change the radix from 16 to 8. Unicode is usually represented like '\u002A'. So it looks like you want:String s = "\\077";
System.out.println((char)Integer.parseInt(s.substring(1), 8));Now all you have to do is parse through the String and replace them, which I think shouldn't be too hard for you now :)

I have a problem with session manager session files because of the invalid json storage data submited by firefox

Hi, i have problem with session manager's session files. The problem is: the submitted storage data from firefox which is put between "storage":{ and its matching closing brace } But in some of my session files there is non equal { and } under storage's braces. I need to get storage data but in my case it is very hard to do. My question is there any char put before or after { and } like /{ or \{ to avoid confusion? If there is not such thing, i think there could be different solution but i am not sure: i look couple of my session files; after "storage":{...} there is ,_"formDataSaved" so i can get storage data in this example ... by looking between "storage":{ and ,"_formDataSaved" easily. Is there every time ,"_formDataSaved" after "storage":{ ? Thank you.

Well, it seems waiting is not my strong suit..! I renamed a javascript file called recovery to sessionstore. This file was in the folder sessionstore-backups I had copied from mozilla 3 days ago, when my tabs were still in place. I replaced the sessionstore in mozilla's default folder with the renamed file and then started mozilla. And the tabs reappeared as they were 3 days ago!
So there goes the tab problem. But again when I started mozilla the window saying "a script has stopped responding" appeared, this time the script being: chrome//browser/contenttabbrowser.xml2542
If someone knows how to fix this and make firefox launch normally, please reply! Thank you

Little Problem with Photoshop CS3

Hi, I have a little problem with Photoshop CS3, I'm not sure if this's because a Windows option that I messed up, but the thing is that I didn't touch any options, or some kind of preferences.
I'm talking about the "little windows" (I don't know the correct name) that come from, in this case, the Filter and Analysis options, they're coming down from their right side, and usually, the come down from their left side. This is really annoying.
Not big deal, but I can't really work properly. I hope you guys can help me, and this's my first post, I hope I didn't break any rule.

Thanks Mylenium, that was the problem, I don't even have a tablet, but that fixed my problem =)
Thanks again.

A little problem with color profiles

I am trying LR and so far I love it, it has successfully replaced RSP for me, and also beat Bibble which I briefly considered but didn't like due to the weird UI.
However, I have a little problem with colours, which has never happened so far with other converters, and I am hoping you can help me to solve it.
My monitor is calibrated with the Spyder and the appropriate profile loaded in the video card.
When I work on a RAW image in LR, and then export a sRGB JPG, and then open it with a browser, or the Win viewer, I see it redder. If I open the image in Faststone, I see it almost sepia.
If I export a TIFF and open it in PS, I see it as in LR, but when I export a JPG from PS (this is my typical workflow), the resulting image has the same problem.
Considering that my entire workflow is in sRGB, can anybody coach me as to the correct settings I must use in order to obtain a final sRGB image with the same colors as in LR? I think that I must be doing something wrong, as the program behaves consistently with PS.
Thank you in advance for any help you will be able to provide.

Funny how it's only Windows users that have this 'problem'.
This is not a 'problem' at all. The only 'problem' here is that you've been used to using non-color-managed applications. Suddenly, Lightroom comes in as a mature, color-managed, program... and you're all going bonkers.
Mac users aren't going bonkers because we're used to using color-managed applications (Preview, Safari, etc. are all color-managed on a Mac).
Let me clarify for you that by 'color-managed', I mean that the software is *not only* reading the embedded profile in your image, but is *also* converting, on-the-fly, the RGB values of that image to a new set of RGB values that compensates for the native response of your monitor. Say, for example, your monitor only displays a narrow gamut of reds. Chances are, then, that LR or PS will intelligently compensate for this by saturating reds before sending to your monitor. This is how color management works. You can now imagine the disastrous effects that a bad/inaccurate monitor profile might have...
Your Windows applications, such as 'Viewer', use the Microsoft ICM 2.0 API. This *will* read the embedded profile in an image, but instead of converting to your monitor profile for output, will simply convert to sRGB. That's basically like half-a$$ color-management. Read more about it here:
http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/prork/prdn_img_vkev.ms px?mfr=true
Firefox & IE don't even use the ICM 2.9 API, making them entirely non-color-managed. Whatever the raw RGB values are in your image, these applications spit out at your monitor.
It's very important you understand these simple concepts before proceeding any further.
OK, ready?
The original monitor profile that came with my MacBook Pro (profiled by someone over at Apple generically for all MacBook Pro LCDs, I guess) really seems to have underestimated the gamut of my monitor. Hence, color-managed applications compensated for this be resaturating my images (especially in the oranges/reds) before outputting to monitor. Therefore, images looked really nice and saturated in color-managed applications; however, when I exported them to sRGB JPEGs and then uploaded to the web, they looked desaturated (in Firefox, NOT in Safari, since Safari is color managed). They even looked desaturated on other people's monitors (these 'other people' were your average Joes...).
I then profiled my monitor using an i1 colorimeter. A 3-D plot of my monitor profile now showed that it actually had a much larger gamut than what Apple had predicted in their profile (but this gamut was still much smaller than sRGB, or the gamut of my Dell LCD or Sony CRT, etc.). Therefore, now, LR and PS, using this new profile, showed images much less saturated. Now when I made my edits, and then exported to sRGB JPEGs, images looked slightly *more* saturated in non-color-managed applications and on other people's computers.
So, you see, your monitor profile affects how you make adjustments/edits in color-managed programs. If your hardware profiler profiled your monitor incorrectly (which I assume is the problem here), then you may be over-saturating certain colors within LR, skewing those RGB values so that a non-color-managed program, which will not re-correct these values as LR is doing, will display the image with too much, say, red.
Bad monitor profiling also explains why you see this problem only on certain images/colors... if it were a LR problem, you'd most likely see it on every export. The color variance is more than likely due to a bad monitor profile that is not accurately describing your monitor's native response... hence LR/PS are incorrectly adjusting your images before sending to the monitor.
And at this point, please don't resort to saying "but the colors in the web browser look 'right' and LR looks 'wrong'". This statement has no meaning, as what looks 'right' to you in your web browser might look horrible to someone else with a different monitor. The point of color-management is to minimize these differences. For example, I was very unhappy by how desaturated my images looked on the web compared to in PS before I calibrated my monitor. Now, images look slightly *more* saturated on the web than in LR/PS, which I'm OK with. *Should* they look the same? Heck no. Similar? Yes. Is it better if they do look the same after hardware profiling? Yes, if your main goal is web export, but, keep in mind, the only way they *would* look the same after PROPER hardware profiling would be if your monitor happened to have a very sRGB-like response (to explain this would take another few paragraphs... but you should be able to figure it out if you ponder a bit).
I hope this is making sense. Let me ask you a couple questions now:
1.) For your headshot image, IMG_8860, which colors look 'right' to you -- the colors in LR, or the colors upon export (i.e. the headshot on the left or the right in your link above)?
2.) How exactly did your profile your monitor? Was it in the dark? I had quite a bit of variance in my monitor profile depending on whether or not the Mac OS X dock was visible at the bottom of the screen -- the light from the dock leaked into the colorimeter which then led to profiles that generated yellow/green color casts.

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(...) ... { ... }
}

Servlets - problem with session

Hi there ppl,
I have a login servlet which is called form a link in a static html page. The doGet() method is as below:
public void doGet(HttpServletRequest request,
          HttpServletResponse response)
     throws ServletException, java.io.IOException
     HttpSession session = public void doGet(HttpServletRequest request,
                              HttpServletResponse response)
                              throws ServletException, java.io.IOException
          HttpSession session = request.getSession(false);
          RequestDispatcher rd = request.getRequestDispatcher("/login.jsp");
          response.setContentType("text/html");
          //PrintWriter out = response.getWriter();
          if(session != null){
               //display members page(with users name as a welcome)
               System.out.println("in login servletb");
          else{
               System.out.println("in login servlet");
               request.setAttribute("membersName", "adom");
               rd.forward(request, response);
               //out.close();
     RequestDispatcher rd = request.getRequestDispatcher("/login.jsp");
     if(session != null){
     //display members page(with users name as a welcome)
     System.out.println("session exists");
     else{
     System.out.println("session not exisit");
     request.setAttribute("membersName", "adom");
     rd.forward(request, response);
Problem is when i click on the link in the html page it goes into tthe else statement and displays the login.jsp page fine. But when i click bak on the browser and then click the link agian it goes into the if statemtn..as if a session exists. But why does a session exisit???...if i use request.getSession(false) this shouldnt create a session if one doent already exists so where is this mysterious session being created??
any ideas would be greatly appreaciated
Mycall

yer i do need the session because in my doPost() method of the servlet i create a session once the user logs on with there login/pass. The doGet() method is only to direct the person to the login page. But i want to check for the session in the doGet() incase they have already login in...if so direct them to the main page rather than to the login page agian.
I stuffed up the code in my previous post...everything compiles and works fine apart from the fact that a session is created when it shouldnt be. I did a test println with session.getCreationTime() and it was created the same time the servlet was initial called. However im not sure if it was created by my servlet or if the broswer somehow had something to do with it....hmm is a worry.
Heres the code again...hopefully a bit neater for u :D
public void doGet(HttpServletRequest request, HttpServletResponse reponse)throws ServletException, java.io.IOException{
HttpSession session = request.getSession(false);
RequestDispatcher rd = request.getRequestDispatcher("/login.jsp");
if(session != null){
//display members page(with users name as a welcome)
System.out.println("session exists");
else{
System.out.println("no session");
request.setAttribute("membersName", "adom");
rd.forward(request, response);
thanks agian :)

Purchased ColdFusion 10: Having problem with session variables

My Dept. has just bought CF10 and I'm finally updating my existing web app to CF10 from CF8. My First Problem with CF10 is using session variables.
When using the lower version of CF (since CF 4 to 8) I have never had any problem setting up session variables and getting or using these variables in other pages after a successful login but with CF 10 it seems setting session variables and using them in other pages are a major problems. I'm not sure where have I done wrong in the codes.
First I'm setting the session in my Application.cfc This way:
<cfcomponent displayname="Application" output="true">
<cfset THIS.Name ="MyNewApp"/>
<cfset THIS.ApplicationTimeout = CreateTimeSpan(0,0,20,0) />
<cfset THIS.SessionManagement ="YES"/>
<cfset THIS.SessionTimeout = CreateTimeSpan( 0, 0, 20, 0 ) />
<cfset THIS.SetClientCookies = false />
<cffunction name="OnApplicationStart" access="public" returntype="boolean" output="false">
<cfset application.Main_DSN = "TESTDB">
<cfreturn true />
</cffunction>
<cffunction name="onApplicationEnd" output="false">
      <cfargument name="applicationScope" required="true">
    </cffunction>
<cffunction name="OnSessionStart" access="public" returntype="void" output="false" hint="Fires when user session initializes.">
<cfset session.loggedin = "NO">
<cfset session.username = "">
<cfset session.userrights = "">
<cfset session.usergroup = "">
</cffunction>
</cfcomponent>
After login, user is validated and set values to those session.variables:
........user validation codes here......................
<cfif mylogin NEQ true>
      <cflocation url="/login/login.cfm">
      <cfabort
<cfelse>
      <cfset session.loggedin="Yes">
      <cfset session.username="#Trim(Form.username)#">
     <CFSET qUserRights = LoginObj.getUserRights('#Trim(Form.username)#')>
     <cfset session.userrights = qUserRights>
    <CFSET qUserGroup = LoginObj.getUserGroup('#Trim(Form.username)#')>
        <cfloop query="qUserGroup">
           <cfset session.usergroup = user_group>
           <cfbreak>
        </cfloop>
    
   <cfdump var="#session.loggedin#">
   <cfdump var="#session.username#">
   <cfdump var="#session.userright#">
   <cfdump var="#session.usergroup#">
</cfif>
In index.cfm, Before Login I got:
session.loggedin = NO
session.username = ["empty string"]
session.userrights = ["empty string"]
session.usergroup = ["empty string"]
After a successful Login:
session.loggedin = NO
session.username = ["empty string"]
session.userrights = ["empty string"]
session.usergroup = ["empty string"]
Have I done something wrong? These codes work on CF8. Please help.
I need to mentioned:
CF10 is in Linux and my web app is under https not http. But these session variables should be shared bentween http and https because some older application are still in http.

On which page is the following code?
After login, user is validated and set values to those session.variables:
........user validation codes here......................
<cfif mylogin NEQ true>
      <cflocation url="/login/login.cfm">
      <cfabort
<cfelse>
      <cfset session.loggedin="Yes">
      <cfset session.username="#Trim(Form.username)#">
     <CFSET qUserRights = LoginObj.getUserRights('#Trim(Form.username)#')>
     <cfset session.userrights = qUserRights>
    <CFSET qUserGroup = LoginObj.getUserGroup('#Trim(Form.username)#')>
        <cfloop query="qUserGroup">
           <cfset session.usergroup = user_group>
           <cfbreak>
        </cfloop>
    
   <cfdump var="#session.loggedin#">
   <cfdump var="#session.username#">
   <cfdump var="#session.userright#">
   <cfdump var="#session.usergroup#">
</cfif>

A stupid little problem with FORTE

Hi to everyone,
I'm using FORTE on windows 2000 but I've a little problem: I can't put the characters {} in the source editor.
I've tried with the ASCII code (ALT + 123) and with ALTGR+7 but they don't work. How ca I do?
Thanks

You can copy the them from where you are able to type them, and then paste them in the editor with ctrl+v. To copy, you can use ctrl+c.

Problem with session while sending a multipart-form (a file via post)

I have a problem with the communication between my applet and my server. I use a method to post an xml to my server with the Content-Type "application/x-www-form-urlencoded" and with it I'm not having any problem to preserve the session.
However I use another method I found in the forums to post files and try to adapt it, but I'm being send from the server to the login page because it's not recognizing my session
Can anybody help me? This is my method
public String uploadFile(String adr, BufferedImage img) {
        String res = "";
        String CONTENT_BOUNDARY = "--abvx98734732";
        String s;
        File f = null;
        URL url;
        URLConnection conn;
        try {
            url = new URL(adr);
            conn = url.openConnection();
            conn.setDoOutput(true);
            conn.setRequestProperty("Content-Type",
                    "multipart/form-data; boundary=" + CONTENT_BOUNDARY);
            conn.setRequestProperty("file-Name", "process_image.jpg");
            DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
            wr
                    .write(("--"
                            + CONTENT_BOUNDARY
                            + "\r\n"
                            + "Content-Disposition: form-data; name=\"fileData\"; filename=\""
                            + "process_image.jpg" + "\"\r\nContent-Type: image/jpg\r\n\r\n")
                            .getBytes());
            ImageIO.write(img, "jpg", wr);
            wr.write(("\r\n--" + CONTENT_BOUNDARY + "--\r\n").getBytes());
            wr.flush();
            BufferedReader in = new BufferedReader(new InputStreamReader(conn
                    .getInputStream()));
            while ((s = in.readLine()) != null) {
                res += s;
            in.close();
        catch (MalformedURLException muo) {
            muo.printStackTrace();
        catch (IOException io) {
            io.printStackTrace();
        return res;
    }This is how I preserve session in my other method:
private static final String SESSION_KEY = "_session_id";
URLEncoder.encode(SESSION_KEY, "UTF-8") + "=" +
URLEncoder.encode(sessionId, "UTF-8");
wr.writeBytes(content);
....

Yes, the only way is to pass the value u want in the query string. But make sure that the value is not too large.
In case you have too much info i guess the only way is to circumvent multipart and handle the process in your own custom class, which wont be worth the effort if u need pass only 2-3 small parameters.
Always,
Leo.
Hi,
Before I upload a file, I want to get a few parameter
values (getParameter) on the form first. I've tried
using com.oreilly.servlet MultipartRequest and a few
other free servlets but they require that the file
must to be uploaded first. For example:
MultipartRequest multi = new
MultipartRequest(request,filepath, 10*1024*1024);
//this will instantiate the object and upload the
file
String command = multi.getParameter("command"); //get
the form parameter
Is there any way I can get the parameter first before
uploading the file? I truly appreciate any helps you
can provide me.
Regards,
