How to save the state of ProgrammaticLogin in serlet/JSP?

excuse me,
I login to Sun Java System Application Server Platform Edition 9.0_01 with ProgrammaticLogin in a servlet,and invoke security EJB.But the system show that
I'm not login when I turn to another serelet and invoke security EJB.Should I login for every servlet?
thanks

Somebody please correct me if I'm wrong, but I think you need to add security constraints (in your web.xml) for every servlet/jsp you wish to access login info from. (e.g.: someservlet.getRemoteUser()).
Actually, it's interesting that you have asked this question, because I am facing the same dilemma in my project and I am planning to save username from a secured servlet/jsp into my session and then access that attribute value from other non-secured servlets/jsps.
This is for a forum/chat style page that I wish to have both accessible to non-registred (anonymous, but using a free handle/nickname) and registered users (using reserved handle/nickname) to prevent any user from portraying themselves as another registered user.

How to save the state of a program ?

I am working on a program, where one can open several tabs with JEditorpanes, and in the tabs one can read a webpage. I was wondering if there is a way to save the state of the program. For example the program starts with three tabs, but say that the user opens three more tabs. How would one save this info, so that it could be retrieved again when the program is restarted ?????

Check out java.util.prefs.Preferences. This is the standard API for loading/saving preferences between sessions of an application.

How to save the state of the changed visible layers in pdf, pre-designed in Indesign

Hi,
I have made an Indesign (CS 5.5) file with some textfields (no button), and interactive buttons. And saved it as Interactive PDF.
I have made a fillable form out of the textfields in Adobe Acrobat Pro X, and the interactive buttons are working in PDF.
When you open the PDF in Acrobat Reader or Pro, fill in text and change a state of the button and save the file: all the changes (text and state) are saved.
When you open the PDF in Acrobat Reader or Pro, fill in text and save the file: the changes (text) are saved.
When you open the PDF in Acrobat Reader or Pro, and only change a state of the button and save the file: the changes are NOT saved.
What I mean with states of a button: SHOW/HIDE or ON/OFF etc.
Does anyone know what I'm doing wrong. Or is it not possible to only save changes in states of a button?
Thanks in advance for thinking with me.

You would have to check your color management and things like overprint settings or the ink levels of the color components. Streaking is usually a sign of areas getting oversaturated and the automatic adjustments in the printer driver being unable to compensate. and then of course other factors may figure in like banding inherent in using gradients across large areas, out of gamut issues for certain colors and what have you. You'd have to be much more specific about all of that for anyone to even begin to advise specifically...

How to save final states with simout

The simout function description (html and manual) indicates that it is capable of saving initial or final states, however it does not say how to save the final states or indicate to the function how to do this. How do I indicate that I want the final states? (When I run simout, it acts like its assuming initial states).

When you use the Simout function you are quirying the state of the model as it exists. If you did not immediately prior run a simulation then you will have the output as the initial conditions. If you want the final states then you will have to run a simulation.
If you are doing this you may want to incorporate into your reportior the use of the resumeto and resumefrom keywords. See the following from the manual:
Linearizing About a Final Operating Point
To linearize a single-rate system at a certain operating point, you must first perform:
y = sim(model,t,u)
sys = lin(model,{resume});
The resume keyword indicates that the linearization operating point will be the final operating point of the previous simulation. To save the operating point at th
e end of the simulation specify the lin options resumeto=filename and resumefrom=filename.
Alternatively, you can simulate the model until you reach the desired operating point:
y = sim(model,t,u);
Find the state at that operating point:
[x] = simout(model);
Linearize around the operating point:
sys = lin(model,{u0=u(length(t),,x0=x})
Now it sometimes becomes useful to obtain the operating point without running a simulation for this purpose there is a full featured trim function that is documented pretty well in the online manual... Search "trim"

How to save the string from JTextFied to database?

can i know how to save the data from JTextFied to databse. Is it using update?

The most straightforward way would be something like:
String myKey=myKeyField.getText();
String foo=fooField.getText();
String sql="update mytable set foo='"+foo+"' where mykey='"+myKey+"'";
connection.createStatement().executeUpdate(sql);
This example assumes that the input fields cannot possibly contain quotes or the string won't be built correctly. Which by the way brings up a question I'd be interested in hearing others answer: What do you do about this? Sometimes I use PreparedStatement which handles that problem, other times I write my own little function to escape the string properly.
You can also read the record into a ResultSet and use ResultSet.update(). I'm mostly using mySql and I found that in mySql ResultSet.update just creates a SQL update statement like I did above and executes it, so the only real advantage would be if you find the syntax more convenient. Perhaps other database drivers do something different that would give other pros and cons.

I want to use Get Panel Image in Labview 5.0.1 and need details on how to save the BMP data generated

I am trying to generate an application that saves a copy of its front panel on completion. This is easy to do using an invoke node with Print VI to HTML but this does not work in an .exe format. I have seen elsewhere that you have to use the Get Panel Image method, but no details are supplied in LV 5.0.1 documentation of how to use the "image" data (1-D Unsigned Byte array) that is generated. I want to save this in a format that can then be read as a bitmap in any standard graphics package. Any assistance?

Hi,
If you'd upgrade to LV5.1 or 6 you could use the 'standard' vi's for this.
You need a VI called "Write BMP File.vi". It's not shipped with LV5.0.1.
This vi only uses 3 subVI's, so perhaps someone at NI can convert it and
send it to you (sorry, I won't, it's copywrited).
If you cannot get this VI anywhere, you'll need to figure out the BMP file
format yourself. It's not too complicated, but still could take some days.
Perhaps someone figured it out before LV5.1 was released.
Regards,
Wiebe.

How to save the form data into adobe db?

Hi All,
How to save the form data into adobe db?
I have designed one xdp file.
Through processFormSubmission(), I got the submitted form data as Document obj.
Then I have called the workflow kickoff program.
code:
InvocationRequest request = myFactory.createInvocationRequest ("myprocessname", //Specify the long-lived process name
"invoke", //Specify the operation name
params, //Specify input values (HashMap obj)
false); //Create an asynchronous request
It successfulyy started the workflow, but the submitted form data is not saved anywhere.
And also, How get the form data from tables?
Please provide the solution for the above.
Thanks in advance.
Regards,
Saravanan G

You need to create a process variable of type IN if you want to be able to pass data to your process. Then the params parameter (HashMap) contains a list of all the IN variables with their content that you want to pass to your process. They key is the name of the variable and the value the content. That way you should get it in your process.
Now LiveCycle will create a column in the database for every process variable, so the content will be saved in the database just by creating that process variable.

How to save the data present in TEXT BOX?

Hi friends i am able to create a text editor in one of my screen but i want to know how to save the data when the text is entered in that text box and retrive when they open the screen?

Hi ,
Please check the format below since it is based on a working code
first you need to create a text in s010 function module...
there should be some key based on which you plan to save the text..imagine it is Purchase order then..PO+item numner is always unique.eg:0090010(900PO/item10).so in the code you can append these two and they will be unique..so you can always retrieve them,overwrite,save them anytime you need
**************data declarations
TYPES: BEGIN OF TY_EDITOR,
EDIT(254) TYPE C,
END OF TY_EDITOR.
data: int_line type table of tline with header line.
data: gw_thead like thead.
data: int_table type standard table of ty_editor.
****************fill header..from SO10 t-code..when you save you need the unique key..youfill it here and pass it in save_text function module
GW_THEAD-TDNAME = loc_nam. " unique key for the text -> our unique key to identify the text
GW_THEAD-TDID = 'ST'. " Text ID from SO10
GW_THEAD-TDSPRAS = SY-LANGU. "current language
GW_THEAD-TDOBJECT = 'ZXXX'. "name of the text object created in SO10
*To Read from Container and get data to int_table
CALL METHOD EDITOR ->GET_TEXT_AS_R3TABLE

others = 5.
IF SY-SUBRC 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
loop data from int_table and save to int_line-tdline appending it.
*save the text
CALL FUNCTION 'SAVE_TEXT'
