How to get a parameter without name in JSP?

hi everyone, My question is how to get a parameter without name in JSP? I have two pages, 1.html and 2.jsp.
in 1.html, I embeds some Javascript codes in HTML contents like below ( changed < to ( , > to )):
function toSubWin( obj )
window.open('test.jsp?'+obj.firstChild.toString(),'sw');
(a onClick='toSubWin(this)'style="background:green")focus(/a)
How can I get the parameter in 2.jsp?
THANK YOU IN ADVANCE!!

Does obj.firstChild.toString() evaluate to a "name=value" type of String ?
Or better what does obj.firstChild.toString(),'sw' evaluate to ? It has to end up in a name=value format, else its just gibberish appended to the url.
In the jsp, you have to obviously know the name to get the parameter. There's a getParameterNames() method which returns you a Collection of parameter names as Strings, you could probably use that to retrieve the param values.
Then there's a getParameterMap() method which returns an immutable Map containing parameter names as keys and parameter values as map values. The keys in the parameter map are of type String. The values in the parameter map are of type String array.
However to what ends you employ them in a program which doesnt know its inputs is a different story.
cheers,

  • How to get List Item attachments name without write any custom code or any database query?

    Hi,
    How to get List Items attachments name without write any custom code or any database query?

    You can get it from Rest,
    There are 2 options,
    1) create a 'Result Source' which has a search query for that List which has attachments 
     - Use rest query to get the 'Filename' , it will have the attachment file name 
    For example, if the result source id is : 73e6b573-abf8-4407-9e5f-8a85a4a95159 , then the query will be 
    http://[site URL]/_api/search/query?querytext='*'&selectproperties='Title,Path,FileExtension,SecondaryFileExtension,Filename'&sourceid='73e6b573-abf8-4407-9e5f-8a85a4a95159'&startrow=0&rowLimit=100
    You can refine the query, be giving proper 'querytext'
    2) Use the List rest api
    For example if your list guid is :38d524a1-e95c-439f-befd-9ede6ecd242e
    You can get he attachments for 1st item using this 
    http://[Site URL]/_api/lists(guid'38d524a1-e95c-439f-befd-9ede6ecd242e')/items(1)/AttachmentFiles

  • How to get the current schema name

    Hi,
    Can anybody please tell me how to get the current schema name, there is some inbuilt function for this,but i am not getting that. Please help me.
    Thanks
    Jogesh

    ok folks, I found the answer at Tom's as usual.
    http://asktom.oracle.com/tkyte/who_called_me/index.html
    I rewrote it into a function for kicks. just pass the results of DBMS_UTILITY.FORMAT_CALL_STACK to this function and you will get back the owner of the code making the call as well some extra goodies like the name of the code and the type of code depending on the parameter. This ignores the AUTHID CURRENT_USER issues which muddles the schemaid. Quick question, does the average user always have access to DBMS_UTILITY.FORMAT_CALL_STACK or does this get locked down on some systems?

  • How to get the actual font name from a font file?

    Hi
    I have only the font Path I have to get the font name from that path. Any idea how to get the actual font name?
    Thanks,

    I would ask you these questions:
    Why do you need to do this?  What are you ultimately trying to accomplish?
    Are you really asking about the InDesign SDK?
    Do you really need to get the "name" of a font from an arbitrary file?  Or do you want information about a font installed on the system?  If so, what OS?
    Do you need to be able to handle any font format?
    Which font "name" do you mean?
    What language do you want the name in?
    (1) It's not clear what you're trying to accomplish.  A bit more information about your ultimate goal would be helpful.
    (2) This question is not at all specific to the InDesign SDK.  Are you really trying to do something in the context of an InDesign plug-in?  If so, you probably want to look at IID_IFONTFAMILY and the IFontFamily::GetFamilyName function.
    (3) If you are asking more generally, Windows and Mac both have system API calls to get this information, although those tend to deal with installed system fonts, not with arbitrary font files per se.
    Also, you can parse the name table from a True Type or Open Type font without using any system APIs; as True Type and Open Type are well-documented standards.  I would start by reading these:
    The Naming Table
    Font Names Table
    (4) Although there are other standards, such as Type 1 (PostScript) fonts, and True Type Collection files and other formats, especially on Mac.
    (5) Also, when you start down this road, you will quickly realize that your seemingly simple question is actually ambiguous, and that the answer is kind of complicated, because a font can have many names (a family name, a full font name, a style name, a PostScript name, etc.).
    (6) And not only does a font have multiple names, it can have each of those names in multiple languages and encodings.
    Any clarification would make this a better question.

  • How to get the Portal Page name from PLSQL?

    Can anyone tell me how to get the portal page name from my dynamic page using plsql?
    Apparently you can get the page id and work it out from there, but my calls to get the page id are not returning any values anyway.
    My code for attempting to get the page id is below.
    <oracle>
    declare
    v_pageid varchar2(30);
    begin
    v_pageid := wwpro_api_parameters.get_value('_pageid', '/pls/portal30');
    htp.print('Page is '|| v_pageid);
    end;
    </oracle>
    Ideally I'd actually just like to get the page name. Is there a straightforward way to do this?
    Thanks in advance!
    Sarah

    Few clarifications -
    1. wwpro_api_parameters cannot be used to get default portal
    page parameters such as '_pageid', '_dad', '_schema' etc.,
    2. Page information can be obtained through any components which
    are available in that particular page. For example, in case of
    dynamic page, we need to publish it as a portlet and add it to the
    page. This process creates necessary packages in the DB, but we
    will not have access to the portlet methods.
    So, I would prefer creating a simple DB provider & portlet and access
    page title from its show method as follows -
    //Declare local variable l_page_id, l_page_title as varchar2
    select page_id into l_page_id from wwpob_portlet_instance$ where
    portlet_id = p_portlet_record.portlet_id and
    provider_id = p_portlet_record.provider_id;
    select name into l_page_title from wwpob_page$ where id=l_page_id;
    More information on DB provider can be found at
    http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/articles/understanding.database.providers.html
    Secondly, usage of wwpro_api_parameters.get_value method is
    incorrect. This method expects two arguments -
    <ul>
    <li><b>p_name : </b> The name of the parameter to be returned.</li>
    <li><b>p_reference_path : </b> An unique identifier for a portlet instance on the current page.</li>
    </ul>
    p_reference_path would be something like 99_SNOOP_PORTLET_76535103 and not some type of path as its name suggests.
    The following code fragment fetches all parameters available
    for a portlet.
    Note : Copy this code into 'show' method of your portlet.
    //Declare l_names, l_values as owa.vc_arr
    * Retreive all of the names of parameters for this portlet
    l_names := wwpro_api_parameters.get_names(
    p_reference_path=>p_portlet_record.reference_path);
    * Retreive all of the values of parameters for this portlet
    l_values := wwpro_api_parameters.get_values(p_names=>l_names,
    p_reference_path=>p_portlet_record.reference_path);
    //Loop through these arrays to get parameter information
    htp.p('<center><table BORDER COLS=2 WIDTH="90%" >');
    htp.p('<tr ALIGN=LEFT VALIGN=TOP>');
    htp.tableData(wwui_api_portlet.portlet_heading('Name',1));
    htp.tableData(wwui_api_portlet.portlet_heading('Value',1));
    htp.tableRowClose;
    if l_names.count = 0 then
    htp.p('<tr ALIGN=LEFT VALIGN=TOP>');
    htp.p('<td COLSPAN="2">'
    ||wwui_api_portlet.portlet_text(
    'No portlet parameters were passed on the URL.',1)
    ||'</td>');
    htp.tableRowClose;
    else
    for i in 1..l_names.count loop
    htp.p('<tr ALIGN=LEFT VALIGN=TOP>');
    htp.tableData(l_names(i));
    htp.tableData(l_values(i));
    htp.tableRowClose;
    end loop;
    end if;
    htp.p('</table></center>');
    Hope it helps...

  • How to get the parameter from Java Script into the Parameter crystal Report

    Hi All,
    Crystal Report is integrated with Oracle 10g. I created the base SQL query for col1, col2, col3 and col4. Java Script pass parameter value (185) to Col1.
    My question is how to create crystal report to make Col1 as parameter and how to get the parameter value 185(Col1) from Java Script. Is there any additional code I need to include in the crystal report?
    FYI.
    Java script sends the right parameter value.There is no issue in java script.
    This is an automatic scheduled process when batch runs, Java script should pass the parameter value and the crystal report should get the value and produce the output report.

    Not sure if this is an application question or if you are trying to hook into Crystal Reports parameter UI? If the later then no option other than report design. If an application then I can move this to the Java Forums.
    If you are asking how to alter the parameters I suggest you remove the Java reference and post a new question so it's not confusing the issue.
    Please clarify?

    I have lost sound on my iPad in apps unless I use headphones ,does anyone know how to get sound back without them .I have used the mute volume on the bar at bottom of screen and the slider volume control there only shows when headphones are plugged in !
    I also tried resetting settings all to no avail ...I looked up some advice and watched utube video advice on how to fix without success..
    The volume control button on side does not work ,I got the iPad last August and wonder if it is a fault that means I must return it for replacement from where it was purchased ?

    The Retrospect you used way back when is no longer around. The company was sold and that company produced a new version of Retrospect - Retrospect 8.x
    So, as you've been told, you would have to be running a Tiger system with an old version of Retrospect software (5.x or 6.x - you would need to know) assuming you can find the software.
    As best I can remember you cannot extract files from a Retrospect backup except using the software since Retrospect did not normally make a file by file backup rather it created an archive of the files in the backup. I'm assuming that the EMC/Retrospect people have told you that old Retrospect backups are not accessible by Retrospect 8.x?
