Regarding Provisioning a user to Database Access Tables
Hi,
I've just completed with the installation of OIM 9101 and upgradation of 9101 to 9102. I'm facing a bit wierd. When I try to create a GTC for the Database Access Tables, I'm not able to see Database Access Tables option, in the drop down list for the Transport Provider.
I'm a bit confused if I've wrongly upgraded the system or if at all i've missed out some step. Though OIM seems to be ok and working fine.
Any suggestions as to how to solve this ?
Regards
NikhilThanks Prakash,
The issue has been resolved.
I'd like a bit more of your help. I'm facing an error as follows :

Caused by: java.lang.NullPointerException
This Error seems to occur because I was trying to attach certain pre-prop adapters within the default process form that is created while installing the connector. Roaming around the threads here, I came to know that this might be the problem as pre-props don't work fine when applied to the GTC's default form.
To overcome this problem, I've thought of a solution wherein I should create a new Custom Process Form and then apply my pre-props. But for this approach, I'm stuck into the middle. How can I apply a new Custom Form to an existing Provisioning Process ? Is this fesiable ? If yes, where should the changes be made ?
I tried changing the Table Name inside the GTC's provisioning process so that GTC can pick up the my new process form instead of its default process form, but that again gives an error saying :
com.thortech.xl.orb.dataaccess.tcDataAccessException: DB_READ_FAILEDDetail: SQL: select err_key, err_code, err_desc, err_rowver, err_remedy, err_count, err_last_occurance, err_action, err_help_url, err_severity from err where err_code='DOBJ.UPDATE_FAILED'Description: Got a null connectionSQL State: Vendor Code: 0Additional Debug Info:com.thortech.xl.orb.dataaccess.tcDataAccessException
I hope the scenario is clear to you and i'm able to explain upto the mark .. :(
Kindly help me out..

Hi All,
I am using oracle 11g client library on Linux 64bit machine and trying to connect to oracle database using jdbc thin driver.
The url format what I am trying to use is:
jdbc:oracle:thin:@IP address:port:service_name
When service_name = orcl : I am able to connect with the above syntax.
But when the service_name is having . e.g service_name = orcl.177.39.45, with the above format I get the above error.
If I change the URL syntax to following, it works
jdbc:oracle:thin:@IP address:port/service_name
But both seems to be valid syntax.
So I would like to undestand the reason behind the same.
When service_name is having ".", why ":" does not work and "/" works and when the service_name is without " ." , 1st format works.
Is there any specific reason behind same?
Please let me know,
Thanks,
AaratiHello,
as per the suggetion, I replaced the URL in the format
URL=jdbc:oracle:thin:@15.154.47.235:1521/ORCL
original URL :
URL=jdbc:oracle:thin:@15.154.47.235:1521:ORCL
With this I was able to access the main page and was not getting database access.
But when I tried to perform some operations say list the submitted jobs, our application internally contacts Oracle database and gets the information stored in the database.
its not able to get and it throws exception.
So is there any reason behind this?

atYes, but looking at your log, make sure you define it in the logger in capital letters (DBADAPTERLOGGER). I've had issues in the past where i defined the log level as noted in the documentation, and it only outputted the errors because it was outputting in all caps.
The documentation for the connector defines how you should enter your log levels in JBOSS.

Some questions about my database access bean
The following is a bean (minus imports) that access a database and populates several "articles" and then returns a set of them. pretty plain really.
The bean is modified from here to add exception cactching and 'fix' other problems along the way.
http://forum.java.sun.com/thread.jspa?threadID=727979 (thanks evnafets)
The results list is genericified(!) to avoif unchecked calls (casting) in this line result.add(article);
public class dataAccess {
public List getNewsResults() throws NamingException{
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
DataSource ds = (DataSource) envContext.lookup("jdbc/mySite");
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
List<newsArticleBean> result = new ArrayList<newsArticleBean>();
try {
String sql = "SELECT * FROM news, users WHERE news.user = users.username";
conn = ds.getConnection();
stmt = conn.createStatement();
rs = stmt.executeQuery(sql);
stmt.execute();
while (rs.next()) {
newsArticleBean article = new newsArticleBean();
article.setTitle(rs.getString("title"));
article.setAuthor(rs.getString("author"));
article.setEmail(rs.getString("email"));
article.setNews(rs.getString("news"));
article.setPictureURL(rs.getString("pictureURL"));
article.setDate(rs.getDate("date"));
article.setTime(rs.getTime("time"));
result.add(article);
} catch (SQLException e) {
//error message goes here
finally {
try {
if (rs != null) rs.close();
} catch (Exception e) {
//error message goes here
try {
if (stmt != null) stmt.close();
} catch (Exception e) {
//error message goes here
try {
if (conn != null) conn.close();
} catch (Exception e) {
//error message goes here
return result;
}Some questions that would be of great help if answered:
Im not too sure what a context does or what im doing with it here. My current understanding is that it allows concurrent access of the database.
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
DataSource ds = (DataSource) envContext.lookup("jdbc/mySite");This section im having trouble with too.
As I see it:
I set what my sql query will be;
get a connection @ conn
now im not too sure what stmt is getting, is it getting ready to send the query.
stmt does not have an executeQuery() method, so im never actually sure when the sql query gets sent to the database. I have subbed with execute() but it does not take any arguments so the problem of not sending anything remains.
String sql = "SELECT * FROM news, users WHERE news.user = users.username";
conn = ds.getConnection();
stmt = conn.createStatement();
rs = stmt.executeQuery(sql);Any help greatly appreciated.Some questions that would be of great help if

Nops, it has nothing to do with concurrent access. You use tomcat to set up a Connection Pool. This causes the tomcat server to create a pool of reusable connections on startup. The connection pool (or set of Connection objects) are given a name and the server binds the set of objects to this name in a 'registry'.
From the code, you use jndi to access the Connections from the pooled objects. While doing so, you have to provide the jndi name against which this object pool is bound to.
You'll be more clear when you read the fllowing resources.

As I see it:

getting ready to send the query.Yes something of that sort - basically it provides you a wrapper which can accept your query, use the connection object to access the db, execute the query and return a result set.
stmt does not have an executeQuery() method, so im
never actually sure when the sql query gets sent to
the database.er....it has and that's what you use in your code. (http://java.sun.com/j2se/1.5.0/docs/api/java/sql/Statement.html#executeQuery(java.lang.String))
I have subbed with execute() but it
does not take any arguments so the problem of not
sending anything remains.Hmmm....the execute() method is for a different purpose and it does accept arguments (http://java.sun.com/j2se/1.5.0/docs/api/java/sql/Statement.html#execute(java.lang.String))

String sql = "SELECT * FROM news,

How to handle and manage a multi Database access in runtime with LCDS?
Hello there
I got several customer working with the same application and I wonder how, with LCDS, to manage in a runtime a multi dataBase access; without creating a configuration "mxl" file in
the folder catalina for each database.
Indeed, each customer have their own dataBase, and so far, I did not find out how to avoid creating a config xml file in catalina for every single database; which force me to create as well for each customer a folder application, since the name of the config file in catalina require a folder application to be ran under tomcat....
Thus, my question is :
Is there anyway to create only one configuration mxl file in catalina (in the server side) and then from the client side (application) let the user select its environment (meaning its database) to run the application.... this technic can be also used for multi database environment such as : Dev / Test / Prod environment (or database) where the same application can access to.
Please if any one have an idea or already delt with; just let me know, because I'm entering in a bootle neck and the situation is getting serioulsy critical....
RegardsHello Ulrich,
with compact and repair I mean the MSAccess function "Compact and Repair".
Please follow the link below for more details:
http://office.microsoft.com/en-us/access-help/compact-and-repair-an-access-file-HP005187449.aspx
Normally you can execute this function directly in Access or with the Windows ODBC Data Sources Administrator => "Control Panel" => "Administrative Tools" => "Data Sources (ODBC)"...
I want to execute this function via cvi code and not by hand ;-).
Thank you for your support.

1 View linked to 2 CompCont: NullPointer Exception
Hi,
Here is the architecture of my app :
MainView --> CompContA --> ModelA (RFC function A)
........|
........|---> IntCompB --> CompContB --> Model B (RFC function B)
And here is the content of the MainView :
AdviceNumber : [
Z2_I_Rechercher_Avis_Input.AdviceNumber) | RefreshButton1
UserId : [Z2_I_Rechercher_Bottin_Input.UserId) | RefreshButton2
Name : [Z2_I_Rechercher_Avis_Input.Output.It_Infos_Bottin.Name)
Now, my application works when I populate an AdviceNumber and press the RefreshButton1. At the return, the name field is refreshed and I use some Java code to move the UserId that my function returned to the UserId of the screen. This works well.
Then if I change the value of the UserId in the screen and press the RefreshButton2, the second function returns me another name, and I use some Java code to move this name into the Name field of the screen. This works well too.
The problem is that I can't use the refreshButton2 first! I get a NullPointer exception.
And I know why, it's because the « Output » structure of my Z2_I_Rechercher_Avis_Input is not initialized (since the refreshButton1 has not been used yet).
But I can't find the right way to code it.
Can you help me, thanks!

I just need to know how to initialize the Output.Struc1 when the user decides to click on the RefreshButton2 First.
It's the line in bold that give me the error (but that line works well when the RefreshButton1 is used first!)

Slow database access across network
I have a postgresql database setup on a server machine and have written a java program in netbeans that accesses it. The problem i have is that running the jar created by netbeans from any other machine on the network has really slow database access but running the program from netbeans itself is fine. Running the jar on the server machine is also fine.
Anyoner got any idea as to why this could be?
TomI don't know if this will help, I'm just wading into writing my own java apps to hit a SQL 2K db. We purchased a SQL2k/JSP driven backend on which we extended their OM to meet our needs. It was build as an extranet product but ran very poorly across the 'Net.
The biggest annoyance was not the actual transaction time of the app but the time it took from the end user to click a button and the start of the transaction.
After much testing I determined it was the JSP.
So what we have done to alieviate the issue is to have multiple regional Tomcats that 'throw' their transactions to a central colocation where the SQL servers sit (so the tomcats do the JSP managment in a sense locally to the end user) . For big clients we actually place a linux/tomcat box at the edge of their firewall. For whatever reason, I'm far too busy to determine the how now that I get the responses I need, this has completely eradicated the annoying pause between user interaction and the actual transaction to the DB server. Extended testing showed the SQL server running in the sub half second range to process a command but the tomcat rendering could take up to 2 to 5 seconds in worst case for no discernable reason. Moving the tomcat frontends to the network segment where the clients we solved it.
Of course I'm digging into swing now too and it has some slowness that the Eclipse zealots say SWT fixes but I haven't the depth or experience to properly judge the camps arguments yet.

Hi All,
I am having major difficulties with my web application on Sun Web Server 6.1.
After a few days of moderate use (ca. 60 database accesses an hour), my web
server locks up and gives time out errors when requests are made.
After discussing this with fellow programmers, I thought my problem
stems from the database access I use. I wasn't using database connection
pooling, so I thought that might be the answer.
Using the Web server's JDBC Connection Pooling, I set up pooling to work with my application.
Everything seemed to work fine, but after a few days of use, the web server once again locked
up.
Below, please find the class I use to query databases. Do you have suggestions as to how to stream this class or suggestions as to where errors might lurk? Can you see any potential issues with the code I have written?
This class is accessed in the following way: From another class, this call is made:

Database access from session bean
Hello,
I have a stateless session bean which performs some complex
calculations, and also does some database access.
For the database access the bean class has a datasource as
follows:
public class TestBean implements SessionBean {
private DataSource ds_;
public void ejbCreate() {
getDataSources();
private void getDataSources() {
try {
Context ictx = new InitialContext();
ds_ = (DataSource)ictx.lookup("java:comp/env/jdbc/TestDB");
} catch (Exception e) {
e.printStackTrace();
throw new EJBException(e);
Now this class has a method (which is also in the remote interface)
calculateSomething(). This method constructs a number of other
objects that do the actual calculation, and one of these objects
does the actual database access. How would another object be able to
use the datasource that was constructed in the bean class?
I could pass the datasource reference to that object, but that would
break my encapsulation. This is because that object does not get
created directly by the bean object, but rather the way the objects
interact is something like A -> B -> C, where A is the TestBean, and
C is the object that does the DB access. If I passed the datasource,
I would need to make B aware of the datasource, which doesn't
seem good design, because B doesn't do any database access.
Alternatively I could do the lookup in class C, but that would
degrade the performance, as an object C gets created and destroyed
every time the calculateSomething() method is called.
A third option I have thought of, is to add a public method to the
bean that returns a connection. Whenever another object gets
created, a reference to the bean object will be passed along. Then,
if another object needs to do database access, it will call back
the bean to get a connection. This seems just as bad (if not worse)
than the first option.
Does anyone have an elegant solution for this situation? What is
the best practice of handling datasources when a bean class doesn't
do the database access itself? In all the examples I've seen so far,
all the functionality was in the session bean class, but again that
doesn't seem good OO design, and would result in a single huge class.
regards,
KostasThanks again to both for the replies. Here are my responses:
Yi Lin: Yes, I know that an entity bean would solve this problem, however it has been decided not to use entity beans so this is not my call (I think the reason entity beans are not allowed in this project is that they are considered risky: there are other applications that access the same database, so if the container caches entity bean data as you describe, then the users might get inconsistent results).
Gerard: Actually object B is the one that has the business logic and C is a peer object that only does database access and no calculaitons. For example B can be Customer, and C CustomerDB. This is why object B does not have any knowledge of datasources or connections. So my design does not appear to be that bad!
As far as the factory you propose is concerned, I cannot understand how this would solve my problem. In order to solve this situation the factory would need to be persistent, i.e. get created by the ejbCreate() method, and destroyed whenever the container decides to destroy the bean. There would be no point in object C creating the factory, as I would have the overhead of doing the JNDI lookup every time I create a C.
So the question remains the same: how would I pass a reference to the factory from A to C without making B aware of it? -
Database Access delays-how to improve upon that?
Hi friends,
I have this simple class,which takes in query and returns the results.I don't know why the database access is so slow,and if i try to add my driver load statements into the constructor the java class starts throwing "null pointer exception"(Java Class code given below)..I don't know much about connection pool,can u just have a look at this simple class,and tell me if there's anything on which i can improve upon and where to add the(*.close() statements).The same query runs instantly if i make a php program.Urgent help needed...please help me guys.

Very fragile. I'm guessing NullPointerExceptions occur if ResultS
is not called first. Have the other method call this one as necessary.

} // Where's the cleanup? You're leaving ResultSet, Statement, Connection open
>It is probably slow because opening connections takes a long time. You may or may not need a connection pool depending on your app. Perhaps you can just open a connection at the beginning and leave it open until your app finishes. That should reduce the overhead and still be very simple.
