Access Reliability in Web Application

Does anyone have recommendation on using Access database in
Web application.
I have always used Access, but recently heard that it can
cause great problems if more than one user is accessing information
at the same time.
Is there anyway around this or do I need to switch to MySql?
The application is written entirely within Coldfusion, using
a DSN for the Access DB.
This is a small application and it would be rare that more
than one user would be into the same table at one time but it could
happen, as there is a login and the users table would be accessed
each time someone logs in.
Any insight would be helpful. I really don't want to have to
redo the database.
so far there have been no problems but I would be in a fix if
the system crashed.
Thanks.

think it would be to migrate to MySQL from Access?
Anyone have experience with this?
Thanks!
The work might not be hard, but there is an awful lot of it.
I changed one from Access to Oracle once. What I did was:
1. Create the Oracle tables and sequences.
2. Transfer the existing data to the new db.
3. Test every single query and rewrite the ones that needed
it.
So far there is no disruption to your production app, until
now.
4. Take the production app offline to freeze the data.
5. Bring the new db up to date.
6. Put your new app into production.

Backup/Recovery from web application

Hello guys,
I am using Oracle 9i as DB and Oracle 9iAS for web application server. I want to provide Backup and Recovery functionality to the user via web. I don't know any thing in this regard.
Is it possible that we can take backup and recovery from web application?
Is there any alternative for this function.
any other comments will be appreciated.
Thank you,

Read this article in order to get an idea about Java Stored Procedures.
Oracle Developer JAVA STORED PROCEDURES
Simplify with Java Stored Procedures
By Kuassi Mensah
Use Java stored procedures to bridge SQL, XML, Java, and J2EE and Web Services.
Stored procedures allow a clean separation of persistence logic that runs in the database tier from business logic that runs in the middle tier. This separation reduces overall application complexity and increases reuse, security, performance, and scalability.
A major obstacle, however, for widespread adoption of stored procedures is the set of various proprietary, database-dependent implementation languages that different database vendors use. The use of Java-based stored procedures fixes this concern. Oracle has implemented ANSI standards that specify the ability to invoke static Java methods from SQL as procedures or functions. This implementation is called simply "Java stored procedures."
In this article, you will learn how Java stored procedures help simplify and increase the performance of your business logic and extend database functionality. I'll show how Oracle enables the use of Java stored procedures within the database. I'll also look at how Java stored procedures access data, and show how to create a basic Java stored procedure.
PL/SQL or Java
When you think of Oracle stored procedures, you probably think of PL/SQL. Oracle, however, has provided Java support in the database since Oracle8i, to offer an open and portable alternative to PL/SQL for stored procedures. I can hear the $64,000 question: "How do I choose between PL/SQL and Java? Should I forget all the things I've been told about PL/SQL and move on to the greener Java pastures?"
Both languages are suitable for database programming, and each has its strengths and weaknesses. In deciding which language to use, here's a general rule of thumb:
Use PL/SQL for database-centric logic that requires seamless integration with SQL and therefore complete access to database objects, types, and features.
Use Java as an open alternative to PL/SQL for database independence, but also for integrating and bridging the worlds of SQL, XML, J2EE, and Web services.
OracleJVM Lets You Run Java within the Database
Since Oracle8i, Release 1 (Oracle 8.1.5), Oracle has offered a tightly integrated Java virtual machine (JVM) that supports Oracle's database session architecture. Any database session may activate a virtually dedicated JVM during the first Java code invocation; subsequent users then benefit from this already Java-enabled session. In reality, all sessions share the same JVM code and staticsonly private states are kept and garbage collected in an individual session space, to provide Java sessions the same session isolation and data integrity capabilities as SQL operations. There is no need for a separate Java-enabled process for data integrity. This session-based architecture provides a small memory footprint and gives OracleJVM the same linear SMP scalability as the Oracle database.
Creating Java Stored Procedures
There are a few steps involved in turning a Java method into a Java stored procedure. These include loading the Java class into the database using the loadjava utility, and publishing the Java methods using a call specification (Call Spec) to map Java methods, parameter types, and return types to their SQL counterparts. The following section shows how to do this.
I'll use a simple Hello class, with one method, Hello.world(), that returns the string "Hello world":
public class Hello
public static String world ()
return "Hello world";
The Loadjava Utility
Loadjava is a utility for loading Java source files, Java class files, and Java resource files; verifying bytecodes; and deploying Java classes and JAR files into the database. It is invoked either from the command line or through the loadjava() method contained within the DBMS_JAVA class. To load our Hello.class example, type:
loadjava -user scott/tiger Hello.class
As of Oracle9i Release 2, loadjava allows you to automatically publish Java classes as stored procedures by creating the corresponding Call Specs for methods contained in the processed classes. Oracle provides Oracle9i JDeveloper for developing, testing, debugging, and deploying Java stored procedures.
The Resolver Spec
The JDK-based JVM looks for and resolves class references within the directories listed in the CLASSPATH. Because Oracle database classes live in the database schema, the OracleJVM uses a database resolver to look for and resolve class references through the schemas listed in the Resolver Spec. Unlike the CLASSPATH, which applies to all classes, the Resolver Spec is applied on a per-class basis. The default resolver looks for classes first in the schema in which the class is loaded and then for classes with public synonyms.
loadjava -resolve <myclass>
You may need to specify different resolvers, and you can force resolution to occur when you use loadjava, to determine at deployment time any problems that may occur later at runtime.
loadjava -resolve -resolver "((* SCOTT) (foo/bar/* OTHERS)
(* PUBLIC))"
Call Spec and Stored Procedures Invocation
To invoke a Java method from SQL (as well as from PL/SQL and JDBC), you must first publish the public static method through a Call Spec, which defines for SQL the arguments the method takes and the SQL types it returns.
In our example, we'll use SQL*Plus to connect to the database and define a top-level Call Spec for Hello.world():
SQL> connect scott/tiger
SQL> create or replace function helloworld return
VARCHAR2 as language java name 'Hello.world () return
java.lang.String';
Function created.
You can then invoke the Java stored procedure as shown below:
SQL> variable myString varchar2[20];
SQL> call helloworld() into :myString;
Call completed.
SQL> print myString;
MYSTRING
Hello world
Java stored procedures are callable, through their Call Spec, from SQL DML statements (INSERT, UPDATE, DELETE, SELECT, CALL, EXPLAIN PLAN, LOCK TABLE, and MERGE), PL/SQL blocks, subprograms, and packages, as well as database triggers. The beauty of Call Spec is that stored procedure implementations can change over time from PL/SQL to Java or vice versa, transparently to the requesters.
Call Spec abstracts the call interface from the implementation language (PL/SQL or Java) and therefore enables sharing business logic between legacy applications and newer Java/J2EE-based applications. At times, however, when invoking a database-resident Java class from a Java client, you may not want to go through the PL/SQL wrapper. In a future release, Oracle plans to provide a mechanism that will allow developers to bypass the Call Spec.
Advanced Data-Access Control
Java stored procedures can be used to control and restrict access to Oracle data by allowing users to manipulate the data only through stored procedures that execute under their invoker's privileges while denying access to the table itself. For example, you can disable updates during certain hours or give managers the ability to query salary data but not update it, or log all access and notify a security service.
Sharing Data Logic Between Legacy and J2EE Applications
Because legacy applications and J2EE applications both invoke stored procedures through the Call Spec, the same data logic can be shared between J2EE and non-J2EE worlds. Thanks to Call Spec, this data logic can be shared regardless of the implementation language used (whether PL/SQL or Java).
Autogeneration of Primary Keys for BMP Entity Beans
When using BMP for EJB entity beans, a bean instance can be uniquely identified by the auto-generated primary key associated with the newly inserted data as a return value for ejbCreate(). You can retrieve this value within ejbCreate() in one database operation by using a stored procedure that inserts the corresponding data and retrieves or computes the primary key. Alternatively, you could insert the data and retrieve the corresponding key (or ROWID) in one SQL statement, using the RETURN_GENERATED_KEYS feature in JDBC 3.0. However, the stored procedure approach is more portable across JDBC driver versions and databases.
You can implement this pattern with these three steps:
Create the Java stored procedure, defining a public static Java method insertAccount() within a public GenPK class. This method will insert data, compute a unique key (by passing out a sequence number), and return the computed key as primary key.
Define the Call Spec.
CREATE OR REPLACE PROCEDURE insertAccount(owner IN
varchar, bal IN number, newid OUT number)
AS LANGUAGE JAVA NAME 'GenPK.insertAccount(
java.lang.String [])';
Invoke the stored procedure within ejbCreate().
Public AccountPK ejbCreate(String ownerName, int balance) throws CreateException
try {
CallableStatement call = conn.prepareCall{
"{call insertAccount(?, ?, ?)}"};
return new AccountPK(accountID);
Custom Primary Key Finders for CMP Entity Beans
Finder methods are used for retrieving existing EJB entity bean instances. Primary key finders allow you to retrieve a uniquely identified EJB instance. For CMP entity beans, the EJB container automatically generates the primary key finder findByPrimaryKey() method, based on declarative description. In some situations, however, you might need more control; for example, you may need a specialized finder such as findByStoredProcKey(). In these situations, you can use Java stored procedures in conjunction with an object relational framework (such as Oracle9i Application Server [Oracle9iAS] TopLink) to implement a custom primary key finder method. After you define the EJB finder as a REDIRECT or NAMED finder, TopLink will generate the SQL query for retrieving the bean instance.
Data-Driven EJB Invocation
In a data-driven architecture, business logic invocation can be triggered as a result of database operations (such as inserts, updates, or deletes). A Java stored procedure implementing the data logic can be declared as a database trigger to invoke EJBs running in a middle-tier J2EE application server. You can make EJB calls by using either standard remote method invocation (RMI) over Interoperable Inter-ORB Protocol (IIOP), using a J2EE 1.3 compatible server, or RMI over a vendor-specific transport protocol (such as ORMI with Oracle9iAS/OC4J or RMI over T3 with BEA WebLogic). Each application server vendor has its own optimized protocol while providing RMI over IIOP for interoperability. Oracle9iAS supports both RMI calls over IIOP and ORMI protocols.
Data-Driven Messaging
Oracle9i Database embeds Advanced Queuing (AQ), which is an integrated, persistent, reliable, secure, scalable, and transactional message-queuing framework. Oracle exposes AQ features to Java developers through the standard Java Messaging System (JMS) API. Java stored procedures can invoke AQ operations through the JMS interface to allow fast, intra-session, scalable, data-driven messaging.
Java stored procedures can use JMS to invoke AQ operations. You can implement this pattern in four steps:
Create and start the JMS Queue (to do so, embed the following operations within a SQL script):
execute dbms_aqadm.create_queue_table(queue_table =>
'queue1', queue_payload_type =>
'SYS.AQ$_JMS_TEXT_MESSAGE', comment => 'a test queue',
multiple_consumers => false, compatible => '8.1.0');
execute dbms_aqadm.create_queue( queue_name => 'queue1',
queue_table => 'queue1' );
execute dbms_aqadm.start_queue(queue_name => 'queue1');
Create the Java stored procedure (a code snippet is shown):
public static void runTest(String msgBody)
try
// get database connection
ora_drv = new OracleDriver();
db_conn = ora_drv.defaultConnection();
// setup sender (cf online code sample)
// create message
s_msg = s_session.createTextMessage(msgBody);
// send message
sender.send(s_msg);
s_session.commit();
// receive message
r_msg = (TextMessage) receiver.receive();
r_session.commit();
// output message text
String body = r_msg.getText();
System.out.println("message was '"+body+"'");
Create the Call Spec:
create or replace procedure jmsproc (t1 IN VARCHAR)
as language java name 'jmsSample.main (java.lang.String[])';
Invoke the stored procedure:
call jmsproc('hello');
Database-Assisted Web Publishing (Cache Invalidation)
One of the common issues application architects must face is how to cache database information reliably to increase overall system performance. JCACHE is an upcoming standard specification (JSR 107) that addresses this problem. It specifies an approach for temporary, in-memory caching of Java objects, including object creation, shared access, spooling, invalidation, and consistency across JVMs. It can be used to cache read-mostly data such as product catalogs and price lists within JSP. Using JCACHE, most queries will have response times an order of magnitude faster because of cached data (in-house testing showed response times about 15 times faster).
In order to track all the changes to the origin data and refresh the cached data, a Java stored procedure is attached to a table as a trigger. Any change to this table will result in the automatic invocation of this stored procedure, which in turn will call out a defined JSP to invalidate the JCACHE object that maps its state to the database table. Upon invalidation, the very next query will force the cache to be refreshed from the database. Next Steps

Extending Database Functionality
One of the great things about running Java code directly in the database is the ability to implement new functionality by simply loading the code or library and using the Call Spec to make the entry points (public static methods) available to SQL, PL/SQL, Java, J2EE, and non-Java APIs. Oracle9i Database customers can easily extend database functionality. Oracle itself leverages this capability for new utilities and packages such as the XML Developer Kits (XDKs).
Bridging SQL, PL/SQL, Java, J2EE, .NET, and XML
The Oracle XDK is written in Java and exposes its public methods as Java stored procedures, extending the database's XML programmability. SQL, PL/SQL, Java, J2EE, and non-Java (.NET) business logic all have access to the XML parser, the XSLT processor, the XPath engine, and XML SQL Utility (XSU).
The XML parser is accessible through the xmlparser and xmldom packages. XSU is a Java utility that generates an XML document from SQL queries or a JDBC ResultSet, and writes data from an XML document into a database table or view. Using XSU, XML output can be produced as Text, DOM trees, or DTDs. XSU is exposed to PL/SQL through the dbms_xmlquery and dbms_xmlsave packages.
Conclusion
The integration of the Oracle database with a Java VM enables the creation of portable, powerful, database-independent data logic and persistence logic. The loose coupling of business logic that runs in the middle tier with data logic that runs in the database tier improves application scalability, performance, flexibility, and maintenance.

Hi,
Request and Response should be part of same agreement. I hope you are not confused between Acknowledgement and Response. Acknowledgement can be received in the same session (sync mode) but Response will always come in a different session and will be treated as a different document. If, for request, party A is initiator and B is responder then for response party B will be initiator and party A will be responder (as Requset and Response are two docs in case of Custom Document)
For configuring X-Path, please refer section 8.3.11 Configuring the XPath Expression for a Custom XML Document at below link -

          java.util.Iterator parentGroups = sapUser.getParentGroups(false);
          while (parentGroups.hasNext()) {
               String parentGroupName = (String) parentGroups.next();
               if (parentGroupName.equals("GRUP.R3_ROLE_DS.Z:EP_XPTO123")) {
                    return true;
catch (WDUMException e) {
     e.printStackTrace();
OBS.: sapUser can be used to access a lot of info regarding the user.
OBS.: you need to add a reference to "com.sap.security.api.sda", that is in the default SC SAP_JEE, if I well remember.

Calling form from web application

i use the below url for calling form from web application.
http://host51.yan.com/forms/frmservlet?form=test&width=700
i would like to know about "frmservlet"
if it's a servlet file then
where its located in application server10g

The servlet is part of the forms-installation on the application-server, on the local OC4J this is located in $ORACLE_HOME/forms/j2ee/formsapp.ear
What exactly do you want to know about the servlet?

Accessing txt files in the App server from web application

Hi All,
We have a use case, where we need to access txt files from the ADF web application.
We will display to the user the path of the file and whenever he/she clicks, it should be downloaded automatically to the users machine.
Environments we need to develop: JDeveloper 10.1.3.4 and Oracle App Server 10.1.3.1
And our server has credentials and only those who have access to the server can access the files.
Point me or suggest me a good solution to this use case.
Regards,
Naga.

Hi Joonas,
i was able to download the files, thanks a lot for your guidance. i will mark your answer as correct.
Can you let me know how to achieve the following usecase.
1. there will be multiple text files in the server i.e., out of our web application context like in some folder
2. And we need to give user a http link and if he clicks on the link that file should be downloaded automatically to his machine.
and we are using oracle app server 10.1.3.4, please point me to some document or example.
thank you.

Accessing AM Client Interface from Web Application

Hi,
I am trying to access some client interface methods that I developed on my application module from a backing bean on my web application and have trouble doing so.
Some background on the problem,
Basically when logging into our application from the front-end, we have to authenticate the user against some custom security code. Part of this code is to validate the user against the Oracle database (i.e. valid oracle db user, and password is valid password to log onto Oracle database). To do this, I developed Client Interface methods on an Application Module. When using the BC Tester in jdev 11g (the latest release), these methods work 100% and validation occurs. On our logon page, I bound these methods to the page definition file. When I then try in the backing bean to call this method, using the code from the ADF 11g Dev guide as below, the DataControl on the action is null at point 3. It does seem to find the action find. I have also tried to actually use the "setParams" method on the action, and then tried the execute(), invoke() + getResult(), and doIt() + getResult() methods, of which none seems to work. All these go past the execute/invoke/do part, but the return value on the execute, as well as the return value from the getResult calls are null.
public String commandButton_action() {
// Example using an action binding to get the data control
public String commandButton_action() {
// 1. Access the binding container
DCBindingContainer bc = (DCBindingContainer)getBindings();
// 2. Find a named action binding
JUCtrlActionBinding action = (JUCtrlActionBinding)bc.findCtrlBinding("SomeActionBinding");
// 3. Get the data control from the iterator binding (or method binding)
DCDataControl dc = action.getDataControl();
// 4. Access the data control's application module data provider
ApplicationModule am = (ApplicationModule)dc.getDataProvider();
// 5. Cast the AM to call methods on the custom client interface
StoreServiceAM service = (StoreServiceAM)am;
// 6. Call a method on the client interface
service.doSomethingInteresting();
return "SomeNavigationRule";
Can somebody perhaps tell me what I am doing wrong, or of a better approach to resolve this problem. If any more info is needed, please let me know.
I did think about binding the action directly to the logon button on the jsf page, but unfortunately there is additional logic/code that is currently in the backing bean that I do not want to move down into the business components, and some code like the lines below that can not be moved.
HttpSession session = (HttpSession)externalContext.getSession(true);
session.setAttribute(SecurityFilter.SESSION_ATTR_USER, securityDto.getUsername());
session.setAttribute(SecurityFilter.SESSION_ATTR_SECRET, securityDto.getPassword());
session.setAttribute(SecurityFilter.SESSION_ATTR_ROLES, securityDto.getRoles());
return "logonSuccess";
Will really appreciate any help.

Hi,
I managed to find some sort of work around.
I actually dragged and dropped the Client Interface for the custom method from the datacontrol onto my jsf page and created an additional button. I then ran the application and everything worked. Afterwards I went back to my jsf page and removed the newly added button again and removed the newly added methods from my page definition file as well. When I run the application now, the exact same code that I used previously, now seems to work. I changed it to use the findDataControl method as Frank suggested, and that also works now.
What i can not figure out though, is what exactly the the dropping of that dataControl method and removing it again changed on my application to make it work now. Can somebody please try this and see if they can find the answer. I have done a small little sample application where I can replicate the problem exactly which I can provide the steps to if needed.

SSO from Web Application to EP

Hi,
We have a requirement where we have to provide SSO from some web application to Portal (EP6 SP15).
This web application will be having link to portal on its pages.
User store for Web Application and Portal is different.
This Web Application can be accessed from Internet.
We have not yet decided about accessing Portal from internet.
Is there any solution to this? Is this doable??
I have looked at thread
SSO from .Net application to SAP Portal
can anyone provide more information??
Thanks in advance

Hi Santosh,
there is not much to explain. It your web app side, you must have some matching table between webAppUser and the portal users and their passwords, like:
webAppUser1 portalUserA xy56123
webAppUser2 portalUserB g6324s3
Your own "integration" checks which user is logged on, takes the portal user name and password and calls the portal with the parameters "j_user" and "j_password" (and "login_submit=true"); for example via the client and a form where these values are put in and the target is requested per POST. And that's it. For the form (including the pwd) would be send to the client from your webApp server, you definitely should use https at least, as already stated.
Hope it helps

Open OBIEE report from web application

Experts, I want to open OBIEE report from a web application. I have a question regarding the security here. Say I login as 'USER1' in web application, I would have to pass 'USER1' in nquser parameter. Correct? Also, this report has access to 'Sales Group' users only. So, does 'USER1' in web application need to be assigned to 'Sales Group'? Or, any user in the web application can open this report as long as I pass nquser in the GOURL.
thx,
parag

You don't need to specify group details.
When the report hits OBIEE, it will determine the permissions based on the nquser.
Hope it helps.

Running Unix Command from WEB-APPLICATION

Hi all,
I want to run unix command from a java-based web application. the basic code part is this ---
public class RunCommand
      public String runIt()
          String s = null, returnString = "";
          Process p=null;
          try
                   Runtime rt = Runtime.getRuntime();
              p = rt.exec("sh testPOC.ksh");
              p.waitFor();
              BufferedReader stdInput = new BufferedReader(new
                   InputStreamReader(p.getInputStream()));
              BufferedReader stdError = new BufferedReader(new
                   InputStreamReader(p.getErrorStream()));
              // read the output from the command
              returnString += "Here is the standard output of the command:<br>";
              while ((s = stdInput.readLine()) != null) {
                  returnString += s;
              // read any errors from the attempted command
              returnString += "Here is the standard error of the command (if any): <br>";
              while ((s = stdError.readLine()) != null) {
                  returnString += s;
          catch (IOException e)
              returnString += "exception happened - here's what I know: ";
              returnString += "error-> " + e.getMessage();
          catch(Exception e)
            returnString += "exception happened - here's what I know: ";
              returnString += "error-> " + e.getMessage();
          return returnString;
}this class is kept as an inner class. The control comes to its outer class, from servlet, from which the runit() is called. but the exception is occuring at line of p=rt.exec(.....). it tells "<command name> : not found transaction completed" [got this using getMessage() method].
i am unable to show(and see, too) the stacktrace, because i don't have access to that test environment and its log. i can't run this in local because its windows one.
now can anyone tell me, where is the problem. is there any limitation in web application server/container? this was successful when i used command prompt writing a .java file. Please help me. Thanks in advance...

Friends, i've got, where the problem is.
when we run a class file directly from a command prompt, we get an environment with that shell window. but for a servlet application running these kind of commands from a class creates kind of child processes. each and every command is executed as a child process of jvm and don't get those environment. we have 'PATH' variable in the environment. when a command (say, 'dir' or 'sh' or 'ls', etc.) is executed, the shell first search for that executable file (i.e. dir / sh / ls) in the given paths in the variable 'PATH'. this is not available for the child commands of jvm. hence the basic commands are searched in the current directory of the jvm and they are failed.
i solved the problem giving full path of the commands. like :
p = rt.exec("/bin/sh runningScript.ksh")

SOA is not required. WebGate is a separate installation, separate from where you install the Oracle Access Manager.
Oracle Access Manager is like the management station, WebGate would typically be installed on a host where a Web Server is running. So WebGate running on the WebServer host would be used to provide access control functions for web pages hosted on Web Server. You will have to do the configuration of WebGate separately after Access Manager has been installed. Please mark answer helpful/correct if helpful.

Direct File System access problems from JAWS application

Hello,
I have built a Web Start application that consists of a Webserver (Jetty) ,
a WAR file and a Java (main) class that deploys the web application on
the server and starts the server. It all works fine, apart from the fact
that I am getting java.security.AccessControlExceptions when I try to
access the local filesystem or system variables like the java.io.tmpdir.
I have signed all the jar files and I included the<security> <allpermissions />
</security> tag in the jnlp file. Still, I can't seem to get out
of the sandbox.
I have read in this article (http://mindprod.com/jgloss/javawebstart.html)
that direct file system access from a Web Start application is impossible
(Quote: "There is still no way for even a signed JAWS app to
find some persistent disk space in an easy way. It pretty well
has to ask the user for the name of some directory to use.")
Is this true?
Thank you,
Peter

Hi Guys,
I found a way to access the local filesystem...
Besides signing all the jar files and including the<security><allpermissions /></security> tag in the jnlp file I have to include this line in the code I execute on the client machine:
System.setSecurityManager(null);
Regards,
Peter
