How to search the function from API Document

Please Help Me!!!
I have problem in search the API functions when I was coding.
Usually I take 1 million times to find the function I want in the search engine and have no time to focus on coding.
Please share me your experience or tools or books to imprement my ability.
Thank you very much!!!

As an index for Java API methods, The Java Developers Almanac 1.4, Volume 1 and 2 by Patrick Chan are handy. For packages and classes, Java API standard javadoc is the best documentation.

How to filter the Files from SharePoint Document Library based upon cloumn value

Hi
I should filter the files from document library. I have column called "Print Status" for the document library the value would be either "Yes" or "No".
Now i should filter out the files which has "Print Status" as a "Yes".
I am using SPFolder and SPFile from SharePoint Object Model to traverse the file in doc library.
How could i do it?
My Sample code:
foreach (SPFolder childFolder in folder.SubFolders)
if (childFolder.Name != "Forms")
    AspControls.TreeNode trn = new System.Web.UI.WebControls.TreeNode(childFolder.Name, "", "~/_layouts/images/itdl.gif", childFolder.ServerRelativeUrl.ToString(), "");
    newNode = TraverseFiles(childFolder, trn);
                            // add the new node to the tree
                            rootNode.ChildNodes.Add(newNode);
                    // loop through the files
                    foreach (SPFile childFile in folder.Files)
                        // create a new node and add to the tree
                        AspControls.TreeNode childNode = new System.Web.UI.WebControls.TreeNode(childFile.Name + " (" + childFile.TimeLastModified.ToShortDateString()
+ ")", Convert.ToString(childFile.Item["ID"]), "~/_layouts/images/" + childFile.IconUrl, childFile.ServerRelativeUrl.ToString(), "");
                        rootNode.ChildNodes.Add(childNode);
Thanks

Why do you transvers the file an not use a camp query? In a CAML query you can filter the print status and are able to get all files and folder objects at once.
Check out the following post: http://social.msdn.microsoft.com/Forums/sharepoint/en-US/8c45b5e2-1fb8-435c-a97d-1d8c6d288d4c/caml-query-to-query-all-the-files-and-folders-in-document-library?forum=sharepointdevelopmentprevious

How to call oracle function from ejb3

i'm trying to call an oracle query-function from ejb3.
The oracle function:
create or replace FUNCTION getSecThreadCount(secId in NUMBER,avai in NUMBER)
RETURN SYS_REFCURSOR is cur SYS_REFCURSOR;
m_sql VARCHAR2(250);
BEGIN
m_sql:='select count(thrId) from thread where secId='|| secid||'
and thrAvai='|| avai;
open cur for m_sql;
return cur;
END;
I'v tried several ways to call it,but all failed:
1. the calling code:
public Object getSectionThreadCount(int secId,int avai){
          Query query=manager.createNativeQuery("{call getSecThreadCount(?,?) }");
          query.setParameter(1, secId);
          query.setParameter(2, avai);
          return query.getSingleResult();
but i got the exception:
Exception in thread "main" javax.ejb.EJBException: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query; nested exception is: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query

PLS-00221: 'GETSECTHREADCOUNT' not procedure or not defined
ORA-06550: row 1, col 7:
PL/SQL: Statement ignored
2. the calling code:
@SqlResultSetMapping(name = "getSecThreadCount_Mapping")
@NamedNativeQuery(name = "getSecThreadCount",
query = "{?=call getSecThreadCount(:secId,:avai)}",
resultSetMapping = "getSecThreadCount_Mapping",
hints = {@QueryHint(name = "org.hibernate.callable", value = "true"),
          @QueryHint(name = "org.hibernate.readOnly", value = "true")})
public Object getSectionThreadCount(int secId,int avai){
          Query query=manager.createNamedQuery("getSecThreadCount");
          query.setParameter("secId", secId);
          query.setParameter("avai", avai);
          return query.getSingleResult();
but i run into the exception:
Exception in thread "main" javax.ejb.EJBException: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query; nested exception is: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query
javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query
Caused by: java.sql.SQLException: lost in index IN or OUT parameter:: 3
By the way, i have successfully called the function from hibernate. And i use oracle 11g, JBoss5 RC1.
Could anyone tell me how to call the function from EJB3?
Thanks.

}Basically you just ignore the refcursor outbound parameter.
This is a stored function, have yet to try outbound refcursor parameters in stored procedures...

How to search a string from the database?

how to search a string from the database? starting with some character

If you're trying to do this in a SELECT, you can use the LIKE verb in your WHERE clause.
Here's an Example
SELECT obj_name FROM tadir
    INTO prog
    WHERE pgmid = 'R3TR'
      AND object = 'PROG'
      AND obj_name LIKE 'Z%'.
In this case it will select every row that obj_name starts with Z.
If you wanted to find every row that the field obj_name contains say... 'WIN' you use LIKE '%WIN%'.

How to get the value from databank

Hi,
How to get the value from databank? and how to set the same value to visual script object?
thanks,
ra

Hi,
You can use GetDatabankValue(HeaderName, Value) to get the value from databank and SetDataBankValue(HeaderName, Value) to set the value to databank.
You can refer to the API Reference to see list of associated functions and techniques we can use with related to Data Bank.
This is the for OFT but if you are using Open Script then you have direct access for getting the databank value but when it comes to setting a value you have to use File operation and write you own methods to do the set operation.
Thanks

How to get the function name/ID of the current page

HI,
I searched the forum and google, but it is not clear on how to get the function name of the current page.
I have 4 functions in my self service A ,B,C,D (seeded page links ) they all have to go to a page called hhhPG. Based on which function user is clicks I have to show the data in hhhPG.
so my question is how to get the function name ? I mean I need to know if user click on link A , B, C or D link and came to this page.
I found below in one forum and also there is getfunctionID in pageContext , but I do not know what to pass to getfunctionid("???") to get value.
FunctionSecurity funcSecurity = pageContext.getFunctionSecurity();
Or is there a better way of know where user is coming from ? like geturl....
Please help, I need this ASAP.
Thank you.

Use below to find out how the user came into the page
FunctionSecurity funcSecurity = pageContext.getFunctionSecurity();
boolean isFunc1 = funcSecurity.testFunction(funcSecurity.getFunction("YOUR_FUNCTION_SHORT_NAME1"));
boolean isFunc2 = funcSecurity.testFunction(funcSecurity.getFunction("YOUR_FUNCTION_SHORT_NAME2"));
boolean isFunc3 = funcSecurity.testFunction(funcSecurity.getFunction("YOUR_FUNCTION_SHORT_NAME3"));
boolean isFunc4 = funcSecurity.testFunction(funcSecurity.getFunction("YOUR_FUNCTION_SHORT_NAME4"));
So one of them will be true based on the function the user came in.
Write your logic based on these flags.

Peddi.

Hi Experts,
Can you please tell me to how to remove the check from ShpmntCostsRel. (field VTTK-    FRKRL) when saving of the shipment document.

shipment cost calculation only on the Leg level and not on header level. Currently a lot of confusion happened after creating the shipment cost document and found that the status is u201CBu201D.

import sun.net.smtp.SmtpClient;
public class SendMailMessageServlet extends HttpServlet {
static final String to = "[email protected]";
        public void doGet(HttpServletRequest req, HttpServletResponse res)
                                        throws ServletException, IOException {
                res.setContentType("text/html");
                PrintWriter out = res.getWriter();
                //grab the values of each field
                String name = req.getParameter("name");
                String feedback = req.getParameter("feedback");
                String mailfrom = req.getParameter("mailfrom");
                //Notify the sender of his/her feedback

                SmtpClient smtp = new SmtpClient(); //assume localhost
                smtp.from(mailfrom);
                smtp.to(to);
                PrintStream msg = smtp.startMessage();
                msg.println("To: " + to); // mailers will display the To: address
                msg.println("From: " + mailfrom); //mailers will display the From: address
                msg.println("Subject: Hello World !");
                msg.println();
                msg.println("Hello World");
                smtp.closeServer();
}Note that the sun.net.smtp.SmtpClient class has limited capabilities. A better alternative is to use the JavaMail API and when you download the JavaMail packages, there are some sample example code that may help you.

How to get the values from popup window to mainwindow

HI all,
   I want to get the details from popup window.
      i have three input fields and one search button in my main window. when i click search button it should display popup window.whenever i click on selected row of the popup window table ,values should be visible in my main window input fields.(normal tables)
   now i am able to display popup window with values.How to get the values from popup window now.
   I can anybody explain me clearly.
Thanks&Regards
kranthi

Hi Kranthi,
Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

Uday

How to get the data from struct data type using java code.
Thanks in Advance.

Hi Rajeev,
To retrieve a FilterContainer you will need to traverse the report structure:
ReportStructure boReportStructure = boDocumentInstance.getStructure();
ReportContainer boReportContainer = (ReportContainer) boReportStructure.getReportElement(0);
FilterContainer boFilterContainer = null;
if (boReportContainer.hasFilter()) {
boFilterContainer = boReportContainer.getFilter();
} else {
boFilterContainer = boReportContainer.createFilter(LogicalOperator.AND);
Calling boDocumentInstance.getStructure() will retrieve the entire structure for the document.
Calling boReportStructure.getReportElement(0) will retrieve the structure for the first report of the document.
Hope this helps.

How to get the values from repeated frame?.

Hi
how to get the values from repeated frame?. i have to disply the first 3 digits in another place in my report.
i have field empno in repeated frame and i want to disply first 3 digits in another place in the same report.
thanks

How often do you need to display it? It sounds like you might want to base a summary on that formula with a function of first or last. If it's a per page basis, it can be a page level summary. If it's at a higher level repeating frame, then you can create the summary at that level. I'd suggest taking a look at the online help for summaries using the first/last functions.
Hope that helps,
Toby
