Syntax for href tag in out.println

Hi,
In the jsp, the table displays document number from the for loop in it.
I'm trying to put a hyperlink using href tag to the document number which is in the value "table.getString("VBELN")"
out.println(var + table.getString("VBELN"));
I do not know the correct syntax or any alternative to acheive the hyperlink for the document numbers displayed in the jsp. One that I tried is
out.println(var + "<a href="">" + table.getString("VBELN") + "</a>");
Appreciate your timely help.
Thanks.

Thanks Ashish.
I too had the same problem and so couldn't post my question properly and completely.
I've sent you an e-mail in reply.
I need to pass parameter and open the URL with the parameter and no toolbars.
Looking forward to your earliest possible reply. Thanks again.

OJ syntax for multi-table left outer join with MS Oracle Driver

I have a multi-table left outer join that works fine in SQL Server ODBC Driver, Oracle ODBC driver 8.01.07.00, but not with Microsoft ODBC Driver for Oracle 2.573.7326.0
SELECT * from { oj A LEFT OUTER JOIN B ON A.col1 = B.col1 LEFT OUTER JOIN C ON A.col1 = C.col1 }
I noticed someone had a similar problem (the proposed solution doesn't work):
http://www.justpbinfo.com/listarchive/msg02874.html
Does anyone know how to get this working with the Microsoft ODBC Driver for Oracle? Or does it just not work?

The Microsoft ODBC Driver for Oracle 2.573.7326.0 does perform the same 'fix up' with {oj} in Oracle 8i. The problem is that it doesn't work when joining more than two tables:
This works:
SELECT * from { oj A LEFT OUTER JOIN B ON A.col1 = B.col1}
This doesn't work:
SELECT * from { oj A LEFT OUTER JOIN B ON A.col1 = B.col1 LEFT OUTER JOIN C ON B.col1 = C.col1 }
(The second query will work with the Oracle Oracle ODBC driver, with a bit of tweaking. But I haven't found a way to get it to work with the Microsoft ODBC Driver for Oracle 2.573.7326.0. My suspicion is that it just doesn't work.)

XML syntax for tags

It has always been a habit of mine to use XML syntax for CF tags since I've been working with XHTML. For instance, I will do <cfset var myVar = "" /> However, I noticed when doing <cfdump var"#myvar#" />, the output is displayed twice. So now I am wondering if whenever I use a /> on something such as cfset, is the tag actually executing twice? How does this affect performance?
I just happened to notice that in CFBuilder, when I do <cfargment name="myVar" required="true" type="string" default="" />, when I go to the next line and start typing <cfarg auto-suggest will select the cfargument tag, but this is only if I use a />. If I omit the ending forward-slash, auto-suggest does not work. That may be a setting specific to CFBuilder, but that wasn't the scope of this question.
What syntax is correct and how does it affect performance?

According to the document I've linked to below; using self-closing CF tags, such as <cfset myname="Bob" /> is permissible. The document also notes exceptions to this such as CFIF and custom tags as examples where a self-closing tag shouldn't be used.
http://livedocs.adobe.com/wtg/public/coding_standards/style.html
Althoguh it doesn't look like it, that's an internal coding standard for one of Adobe's (well: it was Macromedia at the time) internal teams, and is not supposed to be a suggested standard for everyone. I've had this same discussion with them, too.
As Owainnorth (and many others) observe, it's completely doable. My only challenge to it (and it's a challenge I state in an unduly heavy-handed fashion sometimes!) is the nonsensical rationales people use for doing it: making it more like XML, it's good if the CFML blends in better with the XHTML mark-up it's generating, it's tidier, etc.
I hasten to add that Owainnorth's position that he finds it easier to read and assists with code navigation, whilst leaving me with a blank look on my face, is a completely reasonable basis for doing it. I personally don't believe it, but there's no reason why that should bother him (and I'm sure it doesn't).
I think it was reasonable of me to challenge his wording that it's easier to identify where CF code blocks are by looking at the closing slash rather than the tag name; but having explained himself better, I reckon it's not quite so much tosh as it originally sounded. I mean: I still can't see it, but obviously he can, so fair enough.

Can't run java apps with System.out.println on any builder.

Hello,
I'm currently using Vista RC2, which is the immediate problem.
Classes with System.out.println won't launch the console window. As I'm a student and practicing on these steps, I do have quite a problem on my hands. I click on run, build succesfull, nothing happens.
I have tried Netbeans and Jcreator, and gave up on trying different builds, as I reckon I'll have to find some other way to counter this; any way to get println messages working in vista?

It is run as a desktop app, and other runs with commands such as JOptionPane do function, only the println windows don't appear at all. So I think JRE is installed and working.
I did notice there was one command for input where I'd be able to enter it at the bottom of Netbeans.
Like just now I clicked build and run for the following code
import java.util.*;
public class FirstProgram
    public static void main(String[] args)
        System.out.println("Hello out there.");
        System.out.println("I will add two numbers for you.");
        System.out.println("Enter two whole numbers on a line:");
        int n1, n2;
        Scanner keyboard = new Scanner(System.in);
        n1=keyboard.nextInt();
        n2=keyboard.nextInt();
        System.out.println("The sum of those two numbers is");
        System.out.println(n1+n2)
}Resulting in a brief flash of "input" in the output window (which is below the coding window) and it dissapears. But this also occurs when I don't include system scanner code.
Using commands in cmd
java -jar "C:\Users\Alegis\Netb\MyApp\dist\MyApp.jar"
Does not yield desired results either. Nothing happens.

Syntax to pass parameter value to jsp using href in out.println

Hi,
I have the URL in the form as mentioned below:
<a href="b2c/marketing/showDocDetail.jsp"> <%=doc_no%></a>
I've created the hyperlink using href tag to the document number in the jsp using the below syntax.
<% String a1 = "Document ";
       String a2 = "<a href=\"";
       String a3 = "marketing/showDocDetail.jsp\">";
       String a4 = doc_no;
       String a5 = "</a>";
out.println(a1a2a3a4a5);
%>
When clicked the doc_no is passed to backend RFC and export parameter is retrieved to result.jsp where values along with doc_no are displayed.
the value after clicked is not being passed to action.java class that does the retreival.
Needful, backend class, bom, entry in config.xml is all maintained.
Please help me out with the syntax to pass the parameter value into java class

Hi Bharathi,
try below.
<%
       String a1 = "Document ";
       String a2 = "<a href=\"";
       String a3 = "marketing/showDocDetail.do?docNo=";
       String a4 = doc_no;
       String a5 = " \">";
       String a6 = doc_no;
       String a7 = "</a>";
out.println(a1+a2+a3+a4+a5+a6+a7);
%>
I assume doc_no is java variable contains value of document number
Now create action entry in config.xml file. Suppose "actionDoc.java" class process it.
<action path="/marketing/showDocDetail" type="com.xyz.actions.actionDoc">
               <forward name="success" path="/marketing/showDocDetail.jsp"/>
               <forward name="error" path="/marketing/showDocDetail.jsp"/>
</action>
We are passing parameter docNo=doc_no to action class actionDoc.java in this class you can retrieve request parameter docNo from request object and then process it as you want.
Let me know if you face any problem or error.

Oj syntax for outer join

Is there a way to make Crystal Reports XI not generate the {oj ..... syntax for outer joins?
In Crystal Reports 8, you could do a registry change to keep CR from using oj, but that doesn't seem to work on CR XI (or I don't know where to make the registry change)

A: oj syntax for outer join

Outer Join Escape Sequence builds the syntax for ODBC drivers using the outer join syntax in its SQL syntax.
Use Regedit on the problem client machine add following keys:
STEP 1........For Crystal Reports 9: HKEY_CURRENT_USER\Software\Crystal Decisions\9.0\Crystal Reports\Database\QueryBuilder\OuterJoinEscSeq
<<<OR>>>
...................For Crystal Reports 10:HKEY_CURRENT_USER\Software\Crystal Decisions\10.0\Crystal Reports\Database\QueryBuilder\OuterJoinEscSeq
STEP 2........"MSOuterJoinEscSeq"= "insert your ODBC driver name here": List of the drivers that support Microsoft ODBC {oj ..} join escape sequence.
"NoOuterJoinEscSeq"= "insert your ODBC driver name here": List of the drivers that do not support any join escape sequence.
For example...
MSOuterJoinEscSeq = "UVODBC"

Hi,
By default, if the setting has been done, then it appears in defaultTrace as mentioned. For configuration of it, refer to this link.

Thanks for the guidance and the explanations. I've improved my code according to your recommendations (1, 2 &3) and it compiles just fine.
However, the println still doesn't work...but there is improvement:
When I run my applet using the AppletViewer at the very end I get a log of what happened...and it's now showing:
"D:\JBuilder8\jdk1.4\bin\appletviewer.exe Booking.html
total cost of your selection is: �0"
Which means that the println is being called but is not printing where it should be (on my screen)....the other problem is that it is obviously not properly calculating the total cost since it shouldn't be �0.
Here is my new (improved) code, and below is the code for the Courses class (which does some of the calculation):

[svn] 4184: Fix for @ see tag referencing a non-global package function generates an empty link@ href in DITA

Update!
v3.1 has a major bug! Even though it may appear to work properly, strange characters may leak onto the end of URLs, and you may even get segfaults. Sorry I didn't properly test it before releasing it!
Technical details:
I calloc()ed the memory for the link href improperly, per:
link = calloc((noprepend ? 0 : urllen) + i - s, 1);
Once I fixed it with "+ 1", per:
link = calloc((noprepend ? 0 : urllen) + i - s + 1, 1);
it worked great.
I may use a method that doesn't use a calloc() in the future; this works for now, and I'm not gonna knock it...

Why we use logger instead of System.out.println for debugging?

Hi,
why we use logger instead of System.out.println for debugging?
Regard
Sankar

Ya Basha,
good question....
You can use the idoc method to transfer the data when you are having an interface between the sap system and the legacy system......
All the times BDC is not preferable like take the case you developed on upload program with bdc after some days your company thought to go for upgrade the sap vesion from lower version to upper version... in that upgraded version the application may change like sequence of fields or screens at that time you previous bdc program will not work here so u have to develop a new program and and you have to take the things into consideration again...
where as if you use bapi or idoc method it will support the upgradations...
in the case of bdc you have to take the data into flat files.... and then upload it to sap system after all the validations done some times the data which is in the flat file is confidential so there is no security if u take such data in flat file any user can chang the data even though if u maintain the data in application server super user can change the data
where is idoc is fully secured... you can easily establich the interface between the systems and once it is done you can transfer the data with full security because idoc r generated by a program... so there is no manual interaction.....
I think i gave some useful answer to you

Hi, John,
Not that you asked, but as you proabably know, analytic functions are much better at doing this kind of thing.
You may be amazed (as I continually am) by how simple and efficient these queries can be.
For example:
WITH     got_grp          AS
     SELECT     proj_id, proj_start, proj_end
     ,     proj_end - SUM (proj_end - proj_start) OVER (ORDER BY proj_start)     AS grp
     FROM     v
SELECT       ROW_NUMBER () OVER (ORDER BY grp)     AS proj_grp
,       MIN (proj_start)                         AS proj_start
,       MAX (proj_end)               AS proj_end
FROM       got_grp
GROUP BY grp
ORDER BY proj_start
;Produces the results you want:
PROJ_GRP PROJ_START PROJ_END
         1 01-Jan-2005 05-Jan-2005
         2 06-Jan-2005 07-Jan-2005
         3 16-Jan-2005 20-Jan-2005
         4 21-Jan-2005 22-Jan-2005
         5 26-Jan-2005 30-Jan-2005This is problem is an example of Neighbor-Defined Groups . You want to GROUP BY something that has 5 distinct values, to get the 5 rows above, but there's nothing in the table itself that tells you to which group each row belongs. The groups are not defined by any column in hte table, but by relationships between rows. In this case, a row is in the same group as its neighbor (the row immediatly before or after it when sorted by proj_start or proj_end) if proj_end of the earlier row is the same as proj_start of the later row. That is, there is nothing about 03-Jan-2005 that says the row with proj_id=2 is in the first group, or even that it is in the same group with its neighbor, the row with proj_id=3. Only the relation between those rows, the fact that the earlier row has end_date=03-Jan-2005 and the later row has start_date=03-Jan-2003, that says these neighbors belong to the same group.
You're figuring out when a new group starts, and then counting how many groups have already started to see to which group each row belongs. That's a prefectly natural procedural way of approaching the problem. But SQL is not a procedural language, and sometimes another approach is much more efficient. In this case, as in many others, a Constant Difference defines the groups. The difference between proj_end (or proj_start, it doesn't matter in this case) and the total duratiojn of the rows up to that date determines a group. The actual value of that difference means nothing to you or anybody else, so I used ROW_NUMBER in the query above to map those distinct values into consecutive integers 1, 2, 3, ... which are a much simpler way to identify the groups.
Note that the query above only requires one pass through the table, and only requires one sub-query. It does not need a WITH clause; you could easily make got_grp an in-line view.
If you used analytic functions (LEAD or LAG) to compute flag, and then to compute proj_grp (COUNT or SUM), you would need two sub-queries, one for each analytic function, but you would still only need one pass through the table. Also, those sub-queries could be in-line views; yiou would not need to use a WITH clause.

Why doesn't System.out.println work for Palm?

In my Java code,
how come I don't see any output on my screen (Palm Vx) when I try this?
System.out.println("Hello World");
Where is the output really going to???

Hi,
On POSE (Palm OS emulator), the System.out.println() method output is a file called STDOUT.txt, filed in some directory of the emulator.
On the eal device, I think theres no output for system.out.println().

How do I change Transfer Syntax for DICOM images using sample Java sources?

Hi,
I tested using Note:876534.1 Java API samples. It works fine when I put the "Implicit VR Little Endian" DICOM file.
I could insert the DICOM file, also I could get the all DICOM tags correctly by SQL.
But I could not get all DICOM tags when inserted "Explicit VR Little Endian" and "JPEG Lossy" DICOM file.
Also I could not find how to change the Transfer Syntax to orddicom Java API.
How do I change following simple java source for inserting different Transfer Syntax DICOM file?
Connection conn = DriverManager.getConnection(args[0], args[1], args[2]);
System.out.println("Got database connection");
conn.setAutoCommit(false);
Statement stmt = conn.createStatement();
CallableStatement cs = null;
cs = conn.prepareCall("begin ord_dicom.setDataModel(); end; ");
cs.execute();
cs.close();
String rowInsertSQL = "insert into dicom_test (id, dcmobj) values (" + args[3] + ",ordsys.orddicom())";
stmt.execute(rowInsertSQL);
System.out.println("Inserted empty dicom object ...");
String rowSelectSQL = "select dcmobj from dicom_test where id = " + args[3] + " for update";
OracleResultSet rset = (OracleResultSet)stmt.executeQuery(rowSelectSQL);
rset.next();
OrdDicom dcmProxy = (OrdDicom)rset.getORAData("dcmobj", OrdDicom.getORADataFactory());
rset.close();
System.out.println("selected row for update...");
File testFile = new File(args[4]);
boolean success = dcmProxy.loadContent(testFile, true);
dcmProxy.setProperties();
if (success) {
String updateSQL = "update dicom_test set dcmobj=? where id=" + args[3];
OraclePreparedStatement opstmt =
(OraclePreparedStatement)conn.prepareStatement(updateSQL);
opstmt.setORAData(1, dcmProxy);
opstmt.execute();
int contentLength = dcmProxy.getContentLength();
String SOPInstanceUID = dcmProxy.getSOPInstanceUid();
System.out.println("contentLength: " + contentLength);
System.out.println("SOPInstanceUID: " + SOPInstanceUID);
opstmt.close();
Thanks,
Tatsuya

It would go like this
1. TIFF + XML metadata => DICOM image file
you can use the method ord_dicom.createDicomImage(src blob, metadata xmltype, dest blob) to create the DICOM image in a blob.
2, then use the ORDDicom constructor ORDDIcom(data blob) to create an ORDDicom object
3. then use the ORDDicom processCopy method to change the image properties.
Alternatively you can change image properties on the input TIFF image (using ORDImage methods) then create the DICOM image. If you are happy with the image properties then you can skip step 3.
