Need help in writing a small java code

Hi,
I have a small requirement where I need write a small java code. I am thinking of using array. Please suggest if you know the solution:
1. Need to compare user logon id is preset in the lookup table or not.
2. If user id present in the lookup then send type "A" mail
3. If user id in not present in the lookup then send type "B" email.
Please suggest.
Thanks,
Kalpana.

use this code . you have to pass userlogin and lookup name
Public String GetEmail(String UserLogin,String lookupcode)
String email;
try{
tcLookupOperationIntf lookupIntf = Platform.getService(tcLookupOperationIntf.class);
HashMap<String, String> lookupValues = getLookupHashMap(lookupIntf, lookupCode);
String found = lookupValues.get(UserLogin);
if (found!=null) email= "EMAIL A";
else
email= "EMAIL B";
}catch(Exception e){}
return email;
private HashMap<String, String> getLookupHashMap(tcLookupOperationsIntf lookupOperationsIntf, String lookupCode)throws tcAPIException,tcInvalidLookupException,tcColumnNotFoundException {
HashMap<String, String> lookupMap = new HashMap<String, String>();
          tcResultSet resultLookupHashMap = lookupOperationsIntf
                    .getLookupValues(lookupCode);
          int countResultLookupHashMap = resultLookupHashMap.getRowCount();
if (countResultLookupHashMap > 0) {
               for (int i = 0; i < countResultLookupHashMap; i++) {
                    resultLookupHashMap.goToRow(i);
                    lookupMap.put(resultLookupHashMap..getStringValue("Lookup Definition.Lookup Code Information.Code Key"),
resultLookupHashMap.getStringValue("Lookup Definition.Lookup Code Information.Decode"));
return lookupMap;

Unassign user from a OIM Group using API/Java Code

Hello OIMers,
Can you please tell me how should I Un-assign a group membership through code?
This is the case:
When the user is deleted from Active Directory, I want to Unassign the User from a group, assume the name of the group is "FullTime Employees".
Currently How I do this is Click on the User Profile in Admin Console then select Group Membership from drop down and then select unassign for that group.
Please tell me how should I do the above task programmatically, This would solve my problem.
Thanks everyone in advance.

VSN

Hi all,
I am using the following api:
uintgroupf = (tcGroupOperationsIntf)tcUtilityFactory.getUtility(db, "Thor.API.Operations.tcGroupOperationsIntf");
uintgroupf.removeMemberUser(arg0, arg1);
arg0 - is group key............Can you tell me how should I fetch this Group Key??
Thanks.

Can u access Oracle9i Reports objects from Java Code?

Hi,
How can you access Oracle9i Reports (Rel 2) objects like Body, DataSource, Groups etc from Java Code?
What are the available APIs?
I went thru the APIs at http://otn.oracle.com/products/reports/htdocs/getstart/docs/Javadocs/oracle/reports/plugin/definition/package-summary.html
However various constructors stated in these APIs are using classes from "oracle.reports.definition" package which are difficult for me to locate.
For eg. Report constructor is using oracle.reports.definition.RWReport and there is no API documentation available for RWReport class.
Please suggest me the site for the above APIs or the method to get a reference to "Report" instance.
Thanks
Rakesh.

Thanks Tugdual for your quick reply.
Thats exactly what I am trying to do. I want to develop a utility which can have a subset of Report Developer's functionality.
Currently using Reports Developer & Report Wizard, I can create a report by providing SQL statement and few parameters (like Report Style, Calculated Fields, Template file etc). I want to put all these parameters in a XML file and run my java utility (based on the APIs which I am looking for) which will use these XML parameter file and generate a '.rdf' file.
Also, could you please suggest me the site for oracle.reports.definition package API or the way to get a reference to oracle.reports.plugin.definition.Report instance.
Thanks,
Rakesh

Fetch the User Extended Attribute" Group" Value in Java

Hi All,
I have been able to add a User Extended attribute in SIM and wish to fetch its value for a particular user in my java code.
kindly help.
Thanks
Sunny

Hi All,
I am able to fetch the value of extended attribute "Group" of type "Select" I added in the Default User Form using user.getAttribute("Group") in my java code of Custom Resource Adapter.
This extended attribute has groups name populated in it. What I am doing now is that I am fetching the Group name value and assing the user this group. This is working fine for me. However, In case user select a different group next time, I need to remove the user from old group and assign him the new group. For this, I need to have the old group value and new group value. I don't know how to retrieve the old group value?
Any pointer on this will be helpful.
Note: I have done the mapping of extended attribute "Group" in my Custom Resource Adapter.
Regards,
Sunny

Hi Gaurav,
Same exception on the same line has been reported and marked as solved here :

Btw, I think this forum is not visited often by JCO and ABAP connectivity experts, so maybe you could get a faster response to your problems while posting in "Java Programming" or maybe in some forum under the category ABAP Development.

SQL in JSP - do I use JAVA code in % ... % or SQL Tag Library ??

I have a small web app that makes needs to make about 12 SQL queries in a JSP and am trying to figure out what is the best way to do this
I had initially coded this using plain JAVA code in the JSP as follows :-
<%
Connection conn = null;
Statement st = null;
ResultSet rs = null;
try {
st = conn.createStatement();
rs = st.executeQuery("select .........");
%>
But then I came across the SQL Tag Library in an article and wonder if this is more efficient code?
If so does anyone have a pointer to a good intro to these tags as they look complicated (I only am doing queries on the SQL database, no inserts or updates)

Sometimes you've gotta do what you've gotta do.
My rule is "no scriptlets".
If you MUST access a database from a JSP, the only right way to do it is to use JSTL <sql> tags.

Please help me transform this C++ code to java code....

Being picky, that's not C++, that's C. Standard headers in C++ dont' have .h after them, loop variables are scoped with the for, you use constants rather than #defines, etc..
C and C++ both don't initialise arrays by default; you'd have to write an initialiser to get it to zero out the array:
int s[sz][sz] = {};gcc will insert a call to memset to zero the array.
If the author was assuming that the array was zeroed out, there would be no point zeroing the first row and column.
The code reads values which haven't been initialised. If you mark such values explicitly undefined, and change the program to report an error when undefined, then you get several cases where the program makes such report.
So either it' s a primitive random number generator (some random number generators use uninitialised memory as a source of randomness), or it's buggy, or it's processing undefined data and throwing away the result. Either way, it cannot be directly be ported to Java if the undefined values (which are limited to a small area of the ouput) are significant.

Should I do this with Java Code or Stored Procs ? (for best performance)

Hi All,
I need to decide where should I implement my business logic, in Java code or Stored procs.
Here is the requirement :
- One Order has 70 products (Order_Table )
- Can be duplicate products, so I have to do summarize / grouping by product
- For every product, I have to check, if it is entitled for a Bonus product, then I have to Insert one to Bonus_Table.
- This is done when/after the transaction is SAVED (COMMIT)
The question is, which one has better PERFORMANCE :
(1) Create a rowsetIterator on the Order details (70 products) and call a stored procedure to do the logic for every single product (so that the Insert to Bonus_Table done in stored proc). means the stored proc will be called 70 times.
OR
(2) After the transaction is COMMITted, call the stored procs ONCE to do the logic for all the products at once.
OR
(3) I do all the logic with Java Code within ADF
Given the requirement above, which approach is most efficient / best performance ?
Thank you very much,
xtanto

Problem with this is that you ask 100 people and you probably get 100 different answers. ;o)
Many would say that you push as much business logic into the database with your data; others might say you only put data in your database and your business logic is kept on the application server.
In reality your would probably have a mix of both and your decision would probably be influenced by your own background ...
Can't be more precise than that.

Thanks in advance,

Java code and jsp interaction

Hi,
How does one interact between java code and jsp page.That is, if the java code does say database connection, the web page should tell that the connection has been made,just like an application but this will work on the web server not in the console.Kindly let me know.
As

Just curious but where do these questions come from? A course you are taking or you are building something for a hobby?
If you are building some small simple web-app it's probably quicker to embed code right onto your JSP page.
There are various levels of abstracting your web-app separating display from logic from the model.
The following are techniques from simple web-apps to more complicated ones.
-Embedding script right into your JSP
-Using beans
-Using custom tags ( I think there are some standard ones now, struts seems to be a popular buzzword)
-Including a servlet to handle your requests redirect, update bean content grab info form your database and forward to a JSP. (Read up on model 2 architecture.)
To include as much detail as possible would be to write a book. Fortunately many have so I don't have to fit one in this tiny reply box.
Hope that was somewhat useful.

Calling Java code inside JSP page and sending toString on object to Servlet

Hi.
I am trying to setup a way to make testing my application easier. Using a web-based method will work best. Here is what I am trying to accomplish:
- Have a web page that will prompt the user to enter data, fill in text fields, make choices, etc. When done, they press the Submit button. I don't need to keep info between sessions. Just open browser, execute, view results, close browser, repeat.
- I then want to take this data and use some Java Classes I have to create a Java object.
- I then want to send the toString() results of this Java object to a known Java servlet. The result of the servlet's actions should be displayed as a response on the screen.
This is what I currently have (Ignore the
's - I don't know why they are showing up - its not important):
Web page:
<html>
<head><title>TestGroup</title></head>
<body>
<form name=f method=post action=http://localhost:100/Servlet>
Name: <br>
Group: <input name=group type=text><br>
<br>
<input type=submit value=Submit>
<input type=reset value=Reset>
</form>
</body>
</html>The Java code in the JSP (where to put it?):
<%
Group g = new Group();
g.setGroupName(request.getParameter("group"));
String output = g.toString(); // I want this to go to the Servlet.
%>But, now I am stuck as to how to piece these together. I have some JSP experience, but not quite like this.
As I said, when the user presses the Submit button, I want to perform the Java code above, and have the results of the toString method sent to the Servlet, plus clear all other parameters (so they are not sent to the servlet).
Does anyone have any advice/comments? I am open to alternative designs too, this is just the simplest one I could think of. If another JSP page is needed, that's fine too.
Thanks.

As I said, when the user presses the Submit button, I want to perform the Java code above, and have the results of the toString method sent to the Servlet, plus clear all other parameters (so they are not sent to the servlet).
Does anyone have any advice/comments? I am open to alternative designs too, this is just the simplest one I could think of. If another JSP page is needed, that's fine too.
Thanks.

Proplem: Access HTMLB controls from java code

Hi,
I am new to iView development for EP6. So my problem should be easy to solve (for you ).
I created in the NW Dev Studio a JSP DynPage.
The following files were created or edited:
1.     JSP file (created)
2.     java file (created)
3.     portalapp.xml (edited)
In order to make the page running (proccessing) I changed the following things:
1.     JSP file Add taglib reference to HTMLB-class
2.     portalapp.xml Remove the native property so the JSP file will not be accessed directly.
Now I want to do the following:
On the JSP page I placed severeal HTMLB controls (textViews).
From the java code I try to access these controls in the doProcessBeforeOutput method and change/set values.
But I get all the time a null-Exception.
Code (JSP)
<%-- mcmsprovider.jsp --%>
<%@ taglib uri= "tagLib" prefix="hbj" %>
<hbj:content id="cntMcmsProvider" >
<hbj:page title="MCMS Provider Dynpage">
   <hbj:form id="frmMcmsProvider" >
             <hbj:textView id="tvwScript" encode="false"></hbj:textView>
             <hbj:textView id="tvwStyle" encode="false"></hbj:textView>
   </hbj:form>
</hbj:page>
</hbj:content>
Code (JAVA):
public void doProcessBeforeOutput() throws PageException {
       this.setJspName("mcmsprovider.jsp");
       TextView tvw = (TextView) this.getComponentByName("tvwStyle");
       tvw.setText("Here the dynamic text");
I also tried to add raw text to the form but also null excpetion:
public void doProcessBeforeOutput() throws PageException {
       this.setJspName("mcmsprovider.jsp");
       Form frmCurrent = (Form) this.getForm();
       frmCurrent.addRawText("<h3>This comes from here</h3>");
My goal is to dynamically add controls to the form, but until now I think it will be a dream:
public void doProcessBeforeOutput() throws PageException {
       this.setJspName("mcmsprovider.jsp");
Form form = (Form)this.getForm();
       TextView tvw = new TextView("tvwDynamic");
       tvw.setText("Here the dynamic control");
       form.addComponent(tvw);
The normal page processing runs:
public void doProcessBeforeOutput() throws PageException {
       this.setJspName("mcmsprovider.jsp");
Any help is greatly appreciated.

Here is the example straight from the PDK documentation. This should help you a little

    //Fill in your output for "normal" content creation mode here
    protected void doContent(IPortalComponentRequest request, IPortalComponentResponse response) {
        IPageContext myContext = PageContextFactory.createPageContext(request, response);
        if (myContext == null) {
            System.out.println("htmlb service did not start up as expected.");
        Form myForm = myContext.createFormDocument("First Experiment");

        myForm.addComponent(myGroup);
        GridLayout gl = new GridLayout();
        myGroup.addComponent(gl);
        if ((lastEvent != null) && (lastEvent.getComponentName().equals("submit"))) {
            String name = myContext.getDataForComponentId("USER_NAME").toString();
            TextView label = new TextView("Hi, " + name);
            gl.addComponent(1, 1, label);
            Button myButton = new Button("goback", "Go back");
            myButton.setOnClick("goBack"); // ignored anyway
            gl.addComponent(2, 1, myButton);
        } else {
            TextView label = new TextView("What's your name?");
            gl.addComponent(1, 1, label);
            InputField inf = new InputField("USER_NAME");
            inf.setType(DataType.STRING);
            gl.addComponent(1, 2, inf);
            Button myButton = new Button("submit", "Tell");
            myButton.setOnClick("submit");
            gl.addComponent(2, 2, myButton);
        myContext.render();

Need Java code for random text.

To all you Java programmer Gurus out there.
How hard is it to make a small Java program whose whole purpose is to ask a user how many random characters they want and then proceeds to generate a text file full of RANDOM characters A-Z and a-z ?
The characters could repeat it does not matter as long as they repeat randomly.
I've found all kinds of code examples for Random password generators and things like that but none quite do what I want them to do.
sample of what the output file might look like
"fdfbgHBukOKiIkolpPkmNytTrFvDsVbNmNHyygrRDeDsSEfFGHGjJkjKKoJH"
Thank You kindly in Advance
