Suggestions/help needed creating portal type page

Let me start by saying I am very new to Java. I'm trying to create a portal - a fairly simple web page where each user who logs in will see only those application links that they are authorized to access. User A will see links to applications X, Y and Z and user B will see links to applications R and Q.
I'm running a Tomcat 6 server, and will be using Java 6 (jsp pages, servlets, etc). I've done some research on things like tomcat realms, ldap, ad, jaas, etc. but I'm still not sure what direction I should be going in. My 'portal'/web page will consist of about 20 application links - some are links out to external web sites/applications (public web sites outside of our network), some are internal applications housed on various in-house servers on our network, some are home-grown, others are 3rd party applications, eventually some will be home-grown java applications. Each application currently has it's own login and password.
I know that I can build a table in a relational database, or update an xml file in Tomcat and use Tomcat realms to determine who has access to what. Are there other options? I can certainly build a table, but I don't want to if there are easier ways - can AD tell me what applications a particular user has access to (so I can determine what links to display)? If so, how? (I don't know much about ad (yet)).
I just don't want to end up building something overly complex, and missing out on something that would make this simpler. Any ideas, suggestions, etc on what I could/should be looking at would be most appreciated.
Thanks!

Unless you know what you're doing with absolute positioning, avoid absolute positioning! Absolute positioning actually takes an element out of the normal HTML document flow and positions it absolutely in relationship with it's first parent with a position other than static - for details read the HTML specs at the W3C.
Ideally you should use the normal HTML document flow. Divs are block level elements meaning that they act like blocks that take up a height (determined by children content) and width (the full width of the page or it's parent container, unless you tell it otherwise).
For your CSS try this:
#techlistcontainer {
    width: 75%;
    margin-top: 0;
    margin-right: 0;
    margin-bottom: 0;
    margin-left: 30;
    padding-top: 0;
    padding-right: 0;
    padding-bottom: 0;
    padding-left: 30;
How does that work with your templates?

Help needed creating consistency across pages

My site is here:
http://www.leaningtowermpls.com/index.php
The horizontal yellow bar at the top is inconsistent across
the pages Home, Menu and Locations. I haven't taken the time to
learn CSS properly yet, and most of the layout is table based. (Not
that I have mastered anything at this point.) This site needs to
get out the door, so if anyone can let me know how to solve this
problem I would really appreciate it.

As discussed - it would be best to base on a simple template
- with
the common items like menu, to yellow bar in the template
etc.
Also you have the css in each file, far better to move it out
to an
external style sheet - so that all pages will behave the
same.

Help in create territory type

Hi,
I'm trying to setup oracle field service fresh instance,
In the territory administration page ,
When i'm trying to create territory type, I found the USAGE field is empty, there is no Choices.
In vision demo there is choises "Trade management, Sales, ...." those Qualifiers
is not enabled for me i don not Know why?
When I'm trying to "Enable Matching Attributes" , I got an error "....., contact your system administrator"
So why i cannot Enable the Matching Attributes?
I think it will solve the problem.
Please help.
Thanks

I'm aslo doing a field service fresh implementation and faced the same isssue. Basically, you create a template for a territory type and that fixes the issue. It's one of the tabs on the top left of the jsp page.

Help Needed with Dynamic RePort PAges

I've created a link that dynamically will generate a data
report from my db. I have about 30 reports the client needs to be
able to run. Do I have to create a separate page for every single
recordset?? Is there a more efficient way to do this??

You could make a drop down menu with the name of the report
in it and then show that report on the redirect page using an if
statement to determine which sql statement to run. Also you can
have multiple recordset on a page.
Are you using php, asp or cfm?

Help in creating a OAF Page

My requirement is to create a page and in that I need to have the fields like date, employee number, batch number, person type, group name and below these fields I need to have an advance table with other fields. User can enter one batch# and employee number and date and for that employee, user should enter the rows in advance table and all these values should store in a single VO including the fields above the advanced table. I am not sure if this will work as we are entering the above fileds one time and multiple rows in advanced table.
If you see any similar page in any of the module, please let me know the responsibility and function, I will check the page and code behind that.
Thanks,
HC

it is not recomendated to have both header master and line child in same table.
But you can create such page. Oracle will not have such page.
what problem are you facing while development.

Help Needed Created Standalone Network for iTunes DJ

I use my MBP to manage backing tracks for a band. I would like to use iTunes DJ for requests from the audience via wireless connection via *iPhone/iPod Touch Remote app*. I would use this option in conjunction with a printed song list and small request cards (for those who don't have iPhones).
I can't connect to an existing network as most venues do not have wireless. I would like to set up my MBP as a wireless base station that can be accessed via an iPhone/iPod Remote app. Besides, I would prefer to have a network that echo's the band's name.
I know I have to use the "*Create computer-to-computer Networks*", but I am unsure of what settings I need to get the network working.
I will use Locations to quickly activate the MBP as the base station.
Any help or suggestion setting up my MBP as a wireless base station would be greatly appreciated.
TIA

Agreed. I'd keep at it yourself. I guarantee it will be something simple.
what are the benefits of a switcher? (never used one before) any recomends?
A switch is just like a hub, except that instead of always sending packets to your entire network, it only sends them where they need to go. The benefits grow with the size and speed of your network. Switches used to be much more expensive than hubs but not any more. Normally I'd recommend almost any Linksys device, but in this case dlink seems to have a better one:

Again, I don't think your dlink hub is responsible for this dramatic bottleneck though.

Solution Design questions/suggestions/help needed

Hi,
I would appreciate any inputs regarding this.
I am thinking of designing Solutions in Solman for our landscape which consists of ECC 6 and PI 7.1; each having a 3 system landscape D-Q-P. Is there an issue if I create Solutions Dev, QA and Prod vs Solutions ECC and PI ? I am more in favor of the former because it allows me easier management of the landscape when I implement System Monitoring, EWA, System Administration to see everything for the critical Prod systems together. Do any of you see any downsides to this approach ? Or any advantages of creating Solution ECC and Solution PI ?
Also, from what I read from the documentation, I would need to create logical component for each system (ZECCDEV,ZECCQA etc) for the systems to show up in the solution landscape ? This is because in the definition of logical components, there is only one field to add the Dev or QA or Prod systems ? I still have to start working on this, so I could be wrong. Please feel free to correct me.
Any inputs would be appreciated since I am fairly new to this.
Thanks,
Shreya

Hello,
I am not really sure what you are asking.
Systems are usually defined (SID) in SMSY, then they are added to a logical component.
Logicals need to be in the customer name space, so they are copied from SAP References to a unique name prefixed by a "Z".
Multiple systems of any system type (PRD, DEV, QAS, TEST, SANDBOX...etc) can be added to a logical component.
One or more logical can then be added to a Solution.
This is basically how the Solution is built. There are some limitations you need to consider when naming systems.
For certain functions, like EWA reports they need to have a unique Installation # + SID, and in the case of a long_sid, it would be the Installation # + (1st 3 chars of the)Long_SID.
So if you want to know if you can have a PI system called DEV, QAS and PRD and a ECC system called DEV, QAS and PRD, you can. But if you name them ECC_DEV, ECC_QAS, and ECC_PRD, then you will have problems.
A logical name must be unique. But they show up in the system landscape as soon as they have been defined.
When the logical is added to the Solution, only system Types of Production are automatically set to "Put in Solution"
Even though you can see the systems of other types in the logical and in the solution. And any system that is not in status "Put in Solution" will not be visible when you try to use it, as an example create an EWA , you would select the solution and not see any other type but production systems to select. This is because system types that are not production need to be manually set to "Put in Solution". This is done in the solution, in Change/Edit mode, and right clicking on the system you want to put in the solution and selecting that option, then saving.
From your questions am and not exactly sure what you were getting at, but I do hope this general info helps.

Paul

Help needed, Createing Dynamic User input

Hello,
I am attempting to create some dynamic user input by "predicting" what the user requires in a text box.
For example if the user enters "Smi" I have a select list pop up which gives the user all options that begin with "Smi".
I am able to achieve the popups but the interface is quite jerky and not terribly responsive I am trying to solve this by using a thread which starts and stops when new input is received but it is still not quite right.
The program uses a Sorted TreeSet to hold the data (I thought this would give me a quick search time) and a simple interface at this stage.
Any help would be fantastic
Thanks in advance :P

Unless you know what you're doing with absolute positioning, avoid absolute positioning! Absolute positioning actually takes an element out of the normal HTML document flow and positions it absolutely in relationship with it's first parent with a position other than static - for details read the HTML specs at the W3C.
Ideally you should use the normal HTML document flow. Divs are block level elements meaning that they act like blocks that take up a height (determined by children content) and width (the full width of the page or it's parent container, unless you tell it otherwise).
For your CSS try this:
#techlistcontainer {
 width: 75%;
 margin-top: 0;
 margin-right: 0;
 margin-bottom: 0;
 margin-left: 30;
 padding-top: 0;
 padding-right: 0;
 padding-bottom: 0;
 padding-left: 30;
How does that work with your templates?

Help needed creating a linked list program

I have been trying to create a linked list program that takes in a word and its definition and adds the word to a link list followed by the definition. i.e. java - a simple platform-independent object-oriented programming language.
the thing is that of course words must be added and removed from the list. so i am going to use the compareTo method. Basically there a 2 problems
1: some syntax problem which is causing my add and remove method not to be seen from the WordList class
2: Do I HAVE to use the iterator class to go thru the list? I understand how the iterator works but i see no need for it.
I just need to be pointed in the right direction im a little lost.................

I have created a 2d image showing a ship on waves. This is done using java2d. I output using JFrame.
I now want to animate it so it moves along the frame size should remain the same but the ship should
appear to move on water... I think time will be involved so the ship moves along the x axis...
please can some one help how to animate this/simulate the ship moving
currently i only have java2d image of a ship and waves..
thanks

Also, this forum is not a site for tutorials as it is asking way too much of a volunteer. The best I can recommend is search here and on google for articles on java animation. You will get better answers and help here with more specific questions.
Another tip: look into the Swing Timer class to help with the animation. You will likely need to use threading as well. If you're not up on this, I suggest the Sun Java Threading tutorials.

Help needed - about change password page

I had created a change password page and successfully connected to the access database via jdbc-odbc bridge. But, there are still some errors with the coding.
The situation is like that: whether the NewPassword==ConfirmPassword or NewPassword!=CofirmPassword or both blank, there will always pop up a message dialog "The confirm password and new password must be same."(which I wrote in JOptionPane) and will not update the database that i had linked. I try to correct it but fail.
Can somebody help me to correct the code below?
Thank you!
========================================================================void jButton1_actionPerformed(ActionEvent e) {
String userid = jTextField1.getText(); //UserName
char[] passwd2 = jPasswordField2.getPassword(); //NewPassword
char[] passwd3 = jPasswordField3.getPassword(); //ConfirmPassword
try {
connection = getDBConnection();
if( passwd2 != passwd3 ){
JOptionPane.showMessageDialog(null, "The confirm password and new password must be same.", "Change Password Fail", JOptionPane.INFORMATION_MESSAGE );
jPasswordField2.setText("");
jPasswordField3.setText("");
else {
String query = "UPDATE UserInfo SET Password = '"+ passwd2 +"' WHERE UserID='" + userid +"'";
Statement statement = connection.createStatement ();
ResultSet resultSet = statement.executeQuery( query );
int result = statement.executeUpdate ( query );
if ( result == 1 )
JOptionPane.showMessageDialog ( null," Password successfully changed", "Password changed", JOptionPane.INFORMATION_MESSAGE );
else {
jPasswordField2.setText( " " );
jPasswordField3.setText( " " );
JOptionPane.showMessageDialog ( null,"Fail to change password.\n Please reenter the new password.","Fail", JOptionPane.INFORMATION_MESSAGE);
catch (SQLException sqlex ){
sqlex.printStackTrace();

Help in creating a confirmation page

i have created an application form in asp and would like new
members to receive email telling them they have successfully
registered and another to myself the administrator telling me that
person x has registered. any assistance would be
appreciated.

Hi,
I use CDOSYS to send email from my ASP. You will first need
to check that your host allows this. It's the default now on
Windows servers so there should not be an issue here.
For more info look here:
http://www.powerasp.com/content/new/sending_email_cdosys.asp
You will then need to build your form, add validation as
needed and build a 'thankyou.asp' page which you redirect to when
the form has been submitted.
The 'thankyou.asp' will include your various SMTP gateway
authentication requirements and also the field names of your form
so as to build your E-Mail.
Something like this maybe:
<%
Dim objMail
Set objMail = Server.CreateObject("CDO.Message")
Set objConfig = Server.CreateObject("CDO.Configuration")
'Configuration:
objConfig.Fields(cdoSendUsingMethod) = cdoSendUsingPort
objConfig.Fields(cdoSMTPServer)="auth.smtp.hostname.co.uk"
objConfig.Fields(cdoSMTPServerPort)=25
objConfig.Fields(cdoSMTPAuthenticate)=cdoBasic
objConfig.Fields(cdoSendUserName) = "mailbox_username"
objConfig.Fields(cdoSendPassword) = "mailbox_password"
'Update configuration
objConfig.Fields.Update
Set objMail.Configuration = objConfig
objMail.From = Request("email")
objMail.To = "[email protected]"
objMail.Subject = "Details from My Form"
objMail.HTMLBody = ""
objMail.HTMLBody = objMail.HTMLBody & ""
& "Contact Name " & "" &
Request.form("name") & " " & " "
objMail.HTMLBody = objMail.HTMLBody & ""
& "Telephone Area Code " & "" &
Request.form("telcode") & " " & " "
objMail.HTMLBody = objMail.HTMLBody & ""
& "Telephone Number " & "" &
Request.form("telnumber") & " " & " "
objMail.HTMLBody = objMail.HTMLBody & ""
& "Email " & "" & Request.form("email")
& " " & " "
objMail.HTMLBody = objMail.HTMLBody & ""
& "Message " & "" &
Request.form("message") & " " & " "
objMail.HTMLBody = objMail.HTMLBody & "Sent at " &
Now() & " " & " " & ""
objMail.Send
If Err.Number = 0 Then
Response.Write(".")
Else
Response.Write("Sorry, There was an error processing your
questionnaire. Please try again. Code: " & Err.Number)
Err.Clear
End If
Set objMail=Nothing
Set objConfig=Nothing
%>
Hope this helps some

Help needed in Portal Search

Hi,
I have built a portal site using HTML Portlets and JavaPDK portlets, now I want to perform search on the contents. I have studied about oracle text and ultra search but could not find any clue how they interact with my dynamic JavaPDK portlet's contents that are coming from my self defined Database Tables.
Further more when I put search box/ simple search portlet in my page and search for any content like 'portal' it shows me some data, but if I search my own keywords that I had defined in the page properties I coulnt find any result.
Please help me in this regards.
Thanks
Jam

No, Portal search will only find content which is added through the Portal UI (Item wizards etc) or through the content management API wwsbr_api. Pending on whether Oracle Text is enabled, the search facility will be able to search within documents, URLs. This is done through a set of Oracle Text indexes :
- WWSBR_CORNER_CTX_INDX on WWPOB_PAGE$
- WWSBR_DOC_CTX_INDX on WWDOC_DOCUMENT$
- WWSBR_PERSP_CTX_INDX on WWV_PERSPECTIVES
- WWSBR_THING_CTX_INDX on WWV_THINGS
- WWSBR_TOPIC_CTX_INDX on WWV_TOPICS
- WWSBR_URL_CTX_INDX on WWSBR_URL$
Any content which is not added to these tables (e.g. a custom portlet which adds document to a custom table with a BLOB colum) will not be searchable through the standard search functionality.

Help needed in data type casting

I have a java program which will receive data and its type in the String format. During program execution, the data in the String data has to be converted into the respective data type and assigned to a variable of that data type so that it could be used in the program. Programmer may not know the type of data that the value has to be converted into.
I really got struck up with this. This is a RMI application and one process node is sending the data to another node in the String format and the type of data it should get converted into so that it can be converted into the respective type and used for computation.
Can you understand what I am asking for ....if you can pls help and it is highly appreciated

I dont know whether i ahve expressed it correctly
look at this code
dataPacket sendtoNode = send.senDatatoNode(inputReq);
String recnodnum = sendtoNode.nodeNum;
String recvarnum = sendtoNode.varNum;
String recvartype = sendtoNode.dataType;
String recvalvalue = sendtoNode.dataVal;
int num; int type;
double result;
// here in this case the result variable type is double
if (recvartype.equals("int")){
 type = 1;
 result = Integer.parseInt(recvalvalue); will pose problem
 else
 if (recvartype.equals("double")){
 type = 2;
 result = Double.parseDouble(recvalvalue);
 else
 if(recvartype.equals("float")){
 type =3;
 result = Float.parseFloat(recvalvalue); will pose problem
 else
 if(recvartype.equals("Boolean")){
 if ((recvalvalue.equals("true")) || (recvalvalue.equals("TRUE")))
 type = 4;
 result = Boolean.parseBoolean(recvalvalue); will pose problem
 else
 if(recvartype.equals("char")){
 type = 5;
 result = (char)recvalvalue; will pose problem
else
if(recvartype.equals("String")){
 type = 6;
 result = recvalvalue; will pose problem
 else
 if(recvartype.equals("byte")){
 type = 7;
 result = Byte.parseByte(recvalvalue); will pose problem
 else
 if(recvartype.equals("long")){
 type = 8;
 result = Long.parseLong(recvalvalue); will pose problem
 else
 if(recvartype.equals("short")){
 type = 9;
 result = Short.parseShort(recvalvalue); will pose problem
 //forvarval varvalue = new forvarval();
 //varvalue.forvarval(recvartype, recvalvalue);
// this has to be done after sorting the problem of type casting string result = recvalvalue;
//result = value; //<this will surely give me a problem as i m assigning string to double>??
send.host(result);
System.out.println("result received and the result is " +recvalvalue );
now i need to assign the converted string in to a variable and use in the compuation ..thts where the challenge n not in teh conversion process...
