Can i set the policy in code not in a policy file

normally starting rmi client with a policy file. and start the client with such JVM parameters: java.security.policy and java.rmi.codebase.
But in jsp how can i specify these JVM parameters.Or can i make the policy in code not in
a file.

You can specifiy inline with code otherwise malicious code would use it the grant all permissions before it wrecks havoc on the system.
When your Servlet engine starts (Tomcat, JBoss, depends on which you are using) there will either be an option to pass in additional policy file, or a policy file will exist inthe servlet engine directory path for you to edit and add your entries to.

  • How can I set the maximum number of restarts for my PDF files?

    I want sent my PDF to a friend,but I just allow him see it only twice.
    How can I set the maximum number of restarts for my PDF files?
    My software edition is Acrobat X

    In the old days when PDFs were only opened on desktops and only in Acrobat or Reader, scripting could fake security features and people were generally convinced. As there are so many ways to open a PDF without scripts ever being run (from mobile devices to in-browser display, or simply opening the file in Illustrator), none of that works anymore.

  • How can I change the policy file?

    I have designed an applet to read a file from the local Machine.
    This applet thro a servlet reads the contents of the file specified.
    I use Tomcat 4.1.12 server and this is an client-server application.
    To read the file in the local machine, I set the permission as follows in the .java.policy file in the Local Machine.
    grant codeBase "http://MyMachine:8080/Example" {
    permission java.io.FilePermission "<<ALL FILES>>", "read, write, delete, execute";
    as the applet file is in the Example of the server "MyMachine".
    Its working and my applet is able to read the file from the local machine it runs.
    Now my problem is I cannot set/change the policy file in every machine where my applet runs.
    Instead if there is a way to change the policy when the applet downloads,that'll be effective.
    That is I donot want to go and change the policy file manually in each and every machine where my applet runs(I donot even know which are the machines going to run the applet).
    Is there any means to acheieve my need?
    Please explain me in detail or direct me to the relevent web sites or links.
    Thank you

    Hi Hosuke,
    I had the same problem, thanks for the advise.
    Still I have a remark to make.
    The thing is that, in order for the applet to have the permission granted (for whatever), you need to have a policy file which you can include in the JAR file (like you explained before) AND also you need to add an entry in the java.security file (located for me: "C:\Program Files\Java\j2re1.4.1_01\lib\security\java.security") that tells the applet where to find all the .policy files.
    Something like: policy.url.4=file:/c:/java.policy
    But since we are talking about an applet we are not able to make changes to this file.
    Maybe you or anyone else knows a workaround for this problem.
    Thanks in advance,
    Ronald Vromans.

  • Can't set the printer (print option not working) in Photoshop CC for Mac (Yosemite)

    I can print from all other apps but a couple of days ago Photoshop just stopped being able to print to my HP Color Laserjet. Photoshop either gives me an error message: will not print until a printer has been set OR it just crashes. I have de-installed and re-installed Photoshop, but the problem did not go away.

    I've tried to add the crash report here but the comment won't save -- should I be sending it to you directly?
    Also, FYI there is someone trolling this forum, posing as an Adobe emplyee who tried to convince that he would de-install my cc app and sell me a different version of Photoshop -!

  • Can I set the Increment/​Decrement to not visible by default?

    The Increment/Decrement attachment to ALL the Numeric controls is a nuisance.  Give me a palette that does not have the Increment/Decrement visible by default and my life will be MUCH better.  I would not mind clicking on a check box if it was needed. 
    How can I make it NOT visible by default?
    Solved!
    Go to Solution.

    Thanks,
    It took me a while but I got it done!  I use the Modern style so it is not that easy as it would be with Silver.  I just think Silver looks 'Bloated'.
    Now I don't have to turn off that check mark everytime i place a numeric control!  YEA

    I can´t set the control panel iCloud. PC writes this: you can not connect because the server error occurred. What´s matters?

    Whenever I log into icloud.com
    Using what version of which browser?
    iCloud.com requires Safari 6 or later, Firefox 22 or later, or Google Chrome 28 or later. Have you tried all of those?
    If you have, have you tried clearing your browser cache and cookies?
    For the first tine since 1989 I'm thinking about buying a PC.
    You'd have exactly the same problems on an 8 year old PC too. It's a bit unreasonable to expect such an old Mac to continue to be compatible as software is constantly updated.
    Saying that, I'm still able to access iCloud.com successfully in Safari v5.0.6 on a PowerPC Mac running Mac OS X 10.5.8, so the problem you're having is likely to be a browser issue, not something inherently wrong with the computer.
    Since all this crap started, Mail won't download my Mac.com or me.com email.
    The iCloud.com website is totally unconnected to Mail's ability to download email via IMAP. Have you checked the mail server settings are correctly setup and up-to-date?

  • Can we set the dynamic data source when using getReportParameters() ?

    Hello!
    I have a report where one of its parameters refers to a list of values (LOVs). This list of values is an SQL Query type. When the data source used in the report is defined in the BI Publisher server, I'm able to get the report parameters using the getReportParameters() function in my application. However, if the data source is not defined the function throws an exception, which is understandable.
    I decided to dynamically set the data source so that even if the data source used by the report is not defined in the BI Publisher server, it still will be able to get the LOVs for the parameter. I tried setting the JDBCDataSource of the dynamicDataSource for the ReportRequest object that I passed to the getReportParameters() function. Please see the sample code below:
    reportRequest.dynamicDataSource = new BIP10.BIPDataSource();
    reportRequest.dynamicDataSource.JDBCDataSource = new BIP10.JDBCDataSource();
    setReportDataSource(reportRequest.dynamicDataSource.JDBCDataSource, connectstr, jdbc, dc); //function to set the values for JDBCDataSource object
    reportParams = webrs.getReportParameters(reportRequest, uid, pwd); //call the getReportParameters
    I was expecting this to work as this is what I did to dynamically set the data source before calling the runReport function. So, my question is -- can we set the dynamic data source when using getReportParameters() ? I tried this both in versions 10g and 11g. It does not seem to work on both versions.

    report_id column of apex_application_page_ir_rpt can help us uniquely identify each saved report.
    We can assign this report_id value to a page item and this page item can be put in the Report ID Item text box of the Advanced section of the Report Attributes page of the IR.
    This should load the saved report identified by report_id and you can get rid of javascript

  • Create Report Layout (Apex 3.2) - How can I set the substitution variables?

    Hi,
    I created a "Report Query" under "Shared Components". I now want to work on the corresponding "report layout". I created a "Generic Columns (XSL-FO)". I read the following in the documentation:
    The following are valid substitution strings:
    #PAGE_HEADER#
    #PAGE_HEADERFONT_COLOR#
    #PAGE_HEADER_FONT_FAMILY#
    #PAGE_HEADER_FONT_SIZE#
    #PAGE_HEADER_FONT_WEIGHT#
    #PAGE_FOOTER#
    #PAGE_FOOTER_FONT_COLOR#
    #PAGE_FOOTER_FONT_FAMILY#
    #PAGE_FOOTER_FONT_SIZE#
    #PAGE_FOOTER_FONT_WEIGHT#
    #PAGE_WIDTH#

    #BODY_FONT_COLOR#
    #BODY_FONT_FAMILY#
    #BODY_FONT_SIZE#
    #BODY_FONT_WEIGHT#
    #BORDER_WIDTH#
    Where can I set the values for these substitution variables in my "Report Layout"? Could someone give an example? I can't seem to find documentation on this.
    Thanks!

    Thanks for the tip however I'm not trying to do this through the print tab, I'm calling the report using the following get_print_document in pl/sql code:
    l_report_blob := apex_util.get_print_document(
    p_application_id => l_application_id,
    p_report_layout_name => l_report,
    p_report_query_name => l_report,
    p_report_layout_type => l_output_format,
    p_document_format => l_output_format,
    p_print_server => null);
    Where could I set these substitution variables ? I'm simply calling a report query and layout created under Shared Components.
    Thanks

  • HELP !!! How can I set the size of each component separately

    Please tell me, when adding components (a mix of
    labels , buttons etc.) on a container (swing), how can I set the size
    of each component separately.
    for example:
    the code here has a mix of button and a grid that is actually another JPanel. Its a part of a bigger
    program. When running the grid is cut (not seen in its full size).
    So, please try to anser also about the specific acse of frame contining another frame in it , and the interior should be right sized.
    The relevant part of the code:
    =========================================
    public class Reversi extends JFrame {
    public static void main(String[] args) {
    Reversi ourGame = new Reversi();
    public Reversi() {
    super("Grid Reversi");
    setSize(new Dimension(300, 300));
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    Grid g = new Grid(); // the grid was built at another part..
    ReversiGame ourGame = new ReversiGame();
    JButton b;
    JFrame f = new JFrame("Hello Java");
    f.setSize(new Dimension(300, 300));
    f.setDefaultCloseOperation(EXIT_ON_CLOSE);
    Container c = f.getContentPane();
    c.add(g,BorderLayout.NORTH );
    c.add(b = new JButton("Hola"), BorderLayout.CENTER);
    //f.pack();
    f.show();

    BorderLayout chooses the sizes of each of the components added to it. Choose a different layout manager (or set the placement/size manually with a 'null' layout)

  • How can i set the alternating colors for a table rows

    Dear All,
    Please any one help me how can i set the Alternating colors for Table Rows.
    i created a theam there i set the background alternating color to brown and i set the table design properity to alternating. but it is not reflecting.

    Hi,
    The design property in Table properties should work for your requirement. Select "alternating" value for design.
    Please see the API below:
    design
    Determines the appearance of the table. The property design can take the following values and is represented by enumeration type WDTableDesign.
    alternating - The table rows are displayed alternately in a different color.
    standard - The table background has one color. The individual table rows are displayed with grid net lines.
    transparent - The table background is transparent. The individual table rows are displayed without grid net lines.
    Check whether you have changed the right property or not? Also table should contain more than one rows to test this scenario.
    Regards,
    Jaya.

  • How many times can you enter the wrong pin code on an iphone before it resets?

    How many times can you enter the wrong pin code on an iphone before it resets itself?

    Hey Robin.T,
    Thanks for the question. The following article provides the answer to your question:
    iOS: Forgotten passcode or device disabled after entering wrong passcode
    http://support.apple.com/kb/HT1212
    If you enter the wrong passcode six or more times, you'll see a message that says one of the following:
    iPhone is disabled
    iPad is disabled
    iPod touch is disabled
    You can also set your passcode lock to wipe the device after 10 unsuccessful attempts (Settings > General > Passcode Lock > Erase Data)
    Thanks,

  • How can I set the data binding between Web Dynpro & Database table

    Dear friend,
    I am a beginner of Web Dynpro. I want to develop my simple project like these:
    1. Create my own database table via Dictionary Project such as TAB_USER and have 3 fields: USER_ID, USER_NAME, USER_POSITION and I have already deployed & archived it.
    2. Create my own Web Dynpro Project, and create the input fields as User ID, User name, User position and icon 'Save' on the selection screen and I have deployed it already.
    For the process, I want to input data at the screen and save the data in the table, please give me the guide line like these:
    1. How can I set the data binding between Web Dynpro and Database table ?
    2.  Are there any nescessary steps that I will concern for this case?
    Sorry if my question is simple, I had try  to find solution myself, but it not found
    Thanks in advances,

    Hi,
    You can write your own connection class for establishing the connection with DB.
    Ex:
    public class  ConnectionClass {
    static Connection con = null;
    public static Connection getConnection() {
    try{
    Context ctx = new InitialContext();
    DataSource ds = (DataSource) ctx.lookup("jdbc/TSPAGE");
    con = ds.getConnection();
    return con;
    }catch(Exception e){
    return null;
    You can place the above class file in src folder and you can use this class in webdynpro.
    You can have another UserInfo class for reading and writing the data into the DB .

  • In EIC, how can we set the SLA of a subcategory to none SLA-related.

    Hi Experts,
    This is our current setup in EIC...
    Category 0501 has an SLA of 8 hours. Subcategory 050101 has to be none SLA relevant. But if we put zero or blank to the SLA Target Value field, it will automatically have a due date defaulted to today. If we will not indicate 050101 on the configuration, it will have the 0501 SLA of 8 hours.
    How can we set the 050101 SLA off?
    The path: IMG --> Personnel Management --> Employee Interaction Center (EIC) --> Interaction Center Web-Client --> Application Functions --> Activity --> Service Level Agreement (SLA) --> Define SLV Properties
    Thanks in advance.

    Hi Harish and Jarret.
    @Harish, I already tried unchecking the checkbox of the Display field but the problem with this is, it will also apply for the rest of the categories. It should only be for this specific subcategory.
    @Jarret, apology, but can you explain to me further about your instruction/advise? I get the feeling that we're on to something with your advise but I didn't quite get it on how to exactly.
    1. You should build the SLA from the lowest level up...
                        -I'm not really sure how, actually.
    2. If you have 8 subcats... will put the 8 entries in the table...
                        -where do I put the 1 subcat? This is because if I don't put that "No SLA" subcat in the table, the due date of that specific subcat will automatically appear todayu2019s date.
    Thanks for both of you. I really appreciate your help.
