Tutorial for Building Mobile Web Applications Using ADF/BC4J-problem

This is the tutorial for:
Develop a offline, Web-based Disconnected Mobile application
Trying to create an offline mobile application using jdeveloper & oracle lite. I want to be able to update the home database after using the application in a disconnected fashion. I do not have a web site, nor is that a feasible option.
Jdeveloper 10.1.3.4 which should be OK as it is higher than the release specified in the tutorial.
webtogo
oraclie lite 10
oracle 10.
I have tried to follow the tutorial completely and I can not get this to connect from webtogo. It runs fine in the jdeveloper usising the container. I created the war file, did the wtg packaging process, opened the mobile manager and published the application & granted access to user 'john'. The samples provided work fine. The new application appears on the webscreen after installing web 0c4j. When I click on it, the address toolbar shows:
http://localhost/webtogo/bc4jtutorial/faces/CustomerOrders.jsp
When it installed mobile client, it installed the CustomerOrders.jsp into:
E:\mobileclient\mobile_client_oc4j\j2ee\mobileclient\applications\mobileclient\bc4jtutorial
an example of the samples that work shows
http://localhost/webtogo/sample6/list
in the browser address line.
Which looks like it's really
E:\mobileclient\mobile_client_oc4j\j2ee\mobileclient\applications\mobileclient\samples\sample6
on the file system
Any one have any ideas? I'll take another solution if someone has found one. However, i am not a great java programmer so thought jdeveloper was great to create forms and access the database.

Hi,
selecting a session bean, this option shows for me in 11.1.2. Make sure that - by accident - you don't select the local or remote interface class

  • Building Offline Mobile Web Applications Using BC4J: A Tutorial

    i try "building Offline Mobile Web Applications Using BC4J: A Tutorial":according with
    http://download-uk.oracle.com/docs/cd/B14156_01/doc/B13788/html/nvbc4jtu.htm
    I've problem on step:13.3 Packaging the JSP Application,in the next step on :6
    Under the Snapshots section, click "Import...". You can now connect to the Oracle Database by providing the following values in the "Connect to Database" dialog.
    Table 13-8 lists values that you must specify in the Connect to Database dialog.
    i enter jdbc:oracle:thin:@192.168.100.10:1521:mag,
    where mag is sid.And Ok,writing Error:similar...
    make sure jdbc driver...in the classpath.
    Thanks.

    You could turn on debugging for your EJB's. Add the following tag to your OC4J start options:
    -Dejb.debug=true.
    Please also check the following logs:
    - $OH\application-deployments\<appName>\OC4J_Namedefault_island_1\application.log
    - the opmn logs for your OC4J instance
    Furthermore you can add some Sys.out statements to your code to see where the problem lies.
    Hope this helps.

  • "SSO" for non-sap web application using SAPGUI to browse?

    I have a web application (non SAP) and the user base are also SAP users in an ABAP system.
    To strengthen the authentication in the web app, I wanted to implement SSO 
    authentication as we pity the users for having to remember so many strong pw's and I
    dont like LDAP based pw sync or other technology I dont understand, because then we are
    just yet another application with the same pw...
    We are having technical problems implementing SSO on the web app side, and are anyway a
    bit sceptical about the user admin / role admin assignment if we get it to work.
    So I have created a transaction in SAP which browses the web app and the intention is to
    send the SAP sy-uname as the web app user. We can control this using s_tcode, and
    an own auth object on the WAS side and a check on the session type before the connection is
    established. In this sense we are dependent on the SAP concept implemented, but even so:
    The role assignment is controlled in the web app itself -> so assume that I am not overly
    worried about unauthorized access to the web application, as they would not have any
    system role for it as their sy-uname does not exist. (Infact we can monitor this)
    The browser on the front end is the SAPGUI with html controls on the SAP side.
    I would be interested in knowing whether anyone else has experience with this approach, and
    whether there are any areas to be carefull of?
    I would also like to know whether this is a strategic error?
    Kind regards,
    Julius

    Hi Julius,
    well, if that web application would run on the same ABAP backend system then the solution described in <a href="http://service.sap.com/~iron/fm/011000358700000431401997E/0612670">SAP Note 612670</a> would be applicable:
    a so-called "Re-entrance ticket" (based on the "SAP logon ticket" SSO proceedings) is issued, transported via the SAPGUI connection and back to the system via the invoked HTML control.
    But for non-SAP web applications that does not help.
    In that case only X.509 client certificates can be used for SSO. Actually, the web application could then also be invoked directly (independent from the SAPGUI session). The user is authenticated based on the X.509 client certificate - and not based on the ABAP userID (of the SAPGUI session).
    Well, if you don't mind the effort you could also use the "SAP Logon Ticket evaluation library" (sapssoext, see <a href="http://service.sap.com/~iron/fm/011000358700000431401997E/0304450">SAP Note 304450</a>) to evalute the SAP logon ticket externally. You'll then need to have a "stub application" at the ABAP side that triggers the http redirect to your external web application. Not a nice solution but a possible one.
    In the future SAML browser artifacts would be an option (preferable to integrate non-SAP applications). But currently that's not available (for NWAS ABAP).
    Cheers, Wolfgang

  • Tipps for building a web application

    I have an idea for a web application. It is fun do do it and if well done, it can earn much money.
    There are two people now working on it, inlcuding me. I develop the concept, write the servlets. He is good at XHTML.
    What other skills does a typical web application need?
    I think we need someone with law skills. If the application comes out, it may not contain any legal weaknesses. Otherwise competitors could destroy us easily. We would have no money to defend ourselves until the application earns money.
    Of course we would also need someone who is good at business laws. A company has to be founded and so on.
    How many people does a medium complex web application need? And what skill sets? What are important things to consider?

    I'd say you need someone with A LOT experience and A LOT of knowledge in existing technologies (if youre doing e 90s style e-hype startup). And have an idea noone had before, because there is A LOT of existing solutions to almost any problem sold A LOT of times from A LOT of huge companies with A LOT of money.
    I dont want to destroy you motivation but i think its gotta be more than 2 Quereinsteiger to earn money with j2ee on web. If it was i'd be riding a ferrarie and not doing student assistance at university or coding web apps for t-systems.
    Still.. DO IT! 'Cause its really fun to learn the stuff and j2ee is a really nice framework. But go into details of j2ee and dont start coding servlets like you would 'code' html.

  • Any good books on web application using JSP/servlet?

    Does anyone know good books on how-to build enterprise web application using JSP/servlet? Aside from the book "Head First JSP/Servlet". Development using Netbeans is more preferrable.

    What about the free web server? JBoss or Glassfish or something else? I prefer web/application server that is fully compatible with JEE6 (unlike Tomcat that can't handle EJB). thanksI'm a JBoss user myself, so naturally I would advise that to you if I were ignorant. I'm not however, so in stead I'll tell you to investigate yourself and see which one you prefer. Nobody is going to tell you which one to use as there is no such thing as a 'better' or 'best' server. Just different servers each with different issues.
    And the community edition of JBoss has had many issues in the past (because Red Hat of course wants to advise you to go to the enterprise platform which ain't cheap), but JBoss 5.1 was a rock solid piece of software that I have had zero problems with (after reading the odd forum or two). JBoss 6 builds on top of JBoss 5.1 and provides the full JEE6 web profile; this means it does NOT provide a certified 'full' JEE6 stack yet. This means nothing however as all the services you may need in an enterprise application are already there.
    BTW: for simple servlet programming, don't neglect Apache Tomcat. Its a lightweight server that just works.

  • Problem with tutorial; "Build a Web Application with JDeveloper 11g Using "

    I've got a rather new installation of Vista Business x64 on my developer rig, and last week I installed the new JDeveloper 11g version. The installation was all-inclusive, no customization on my end.
    In addition I've got a test installation of an Oracle DB 11gR1 on an available server here.
    To familiarize myself with the new JDeveloper I decided to spend some time with the JDeveloper 11g tutorials found here: http://www.oracle.com/technology/obe/obe11jdev/11/index.html.
    I've started twice on the second tutorial, "Build a Web Application with JDeveloper 11g Using EJB, JPA, and JavaServer Faces", and find myself repeatedly stuck at step 19 in section "Creating the Data Model and Testing it".
    It seems impossible to deploy the application to the default application server. The server starts fine on its own, I can access it via the admin console on port 7001 and it looks good. However, when I try to run the HRFacadeBean funny things are happening, symptomized by the following error messages seen in the IDE log-area:
    The "Messages" pane displays:

    I'm not that familiar with these things but it seems to me that there is an issue with port numbers here. The application seems to expect a app.server service at port 7101, but does'nt find one.
    Any suggestions on how to fix this problem would be appreciated?

    Jupp,
    It fails in a similar way.
    What I did was; create a simle 'Hello World' html file, saving it with the jsp extension. In Jdev11g i made a new application and an emtpy project, then loaded the jsp file and made it the default run-target. This compiles nicely.
    When running the project it first attempts to start the WebLogicServer (WLS). After a few minutes it is started as seen in the "Running: DefaultServer" pane:

    The WLS is still running though as I can still access its adm console.
    To me it seems that it is attempting to start a separate instance of the WLS for each run attempt, but then I could be wrong.....:(
    Later I'll try to change the default WLS port from 7001 to 7101 as suggested in another port here.
    I must admit that I'm a bit surprised that the JDev11g doesn't work fine at this very simple level when performing a default install.

  • Building a best practice web application using ColdFusion and Jave EE

    I've been tasked with rewriting a software using ColdFusion.  I cannot seem to find a lot of information on best practice development in ColdFusion.  I am an experience Java developer who has never used ColdFusion before.  I want to build this application using a synergy of ColdFusion and Java EE technologies.  Can someone recommend me a book that outlines how to developer in ColdFusion?  Ideally this book assumes the reader is an experienced developer with no exposure to ColdFusion.  Ideally the methods outlined in the book are still "best practice" methods.

    Requirement is I need to use IBM version of DOJO and JSF but I need to develop the whole application using Eclipse 3.3,2 and Tomcat 5.5.
    With IBM version of DOJO and JSF, will Eclipse and Tomcat help to speed up the development or do you suggest me to go for Rational Application Developer and WebSphere Application Server.
    If I need to go with RAD and WAS, then I am new to RAD and WAS, is it easy to use RAD and WAS for this kind of application and implement web applicaiton fast.
    Any feedback will be great help.Those don't sound like requirements of the system to me. They sound more like someone wants to improve their CV/resume
    From what I've read recently, if it's just fast you want, look at Ruby on Rails

  • SMS Web Services Using ADF BC

    We would like to implement SMS web services using ADF BC. Could u please help us to point us to the right path to start this. The SMS web services will send the logs, errors or exception generated by Oracle ADF based application to mobile phones. The recipient of this is an IT administrator or those who will maintain the application.
    Aside from the software architecture, what are necessary technical implementation or hardware infrastructure needed to implement this? Is the Oracle wireless already integrated with the Oracle 10g AS?

    Are you already familiar with ADF BC and just trying to implement a web service with it?
    I'm not familiar with what special facility an "SMS Web Service" would need. If you can implement it as a simple java class, you can implement it as a simple java class that uses ADF Business Components for sure.

Inspite of deleting the cache as mentioned in the above steps, Firefox still maintains a copy of the page in it's cache.

    We have had this issue many, many times before including on the latest 3.6 rev. It appears that when the applicationCache has an update triggered by a new manifest file, the browser may still use only its local network cache to check for updates to the files in the manifest, instead of forcing an HTTP request and revalidating both the browser cache and the applicationCache versions of the cached file (seems there is more than one). I have to assume this is a browser bug, as one should not have to frig with server Cache-Control headers and such to get this to work as expected (and even then it still doesn't sometimes).
    The only thing that seems to fix the problem is setting network.http.use-cache to false (default is true) in about:config . This helps my case because we only ever run offline (applicationCache driven) apps in the affected browser (our managed mobile apps platform), but it will otherwise slow down your browser experience considerably.

  • Problem in navigation of portletized JSf application using ADF on portal

    Hi All,
    I am implementing a simple scenario wherein i have an ADF Business Component (a simple drop down) and a command button. On click of the button, there is a navigation from one jsp to another.
    I am able to portletize a simple application using ADF Business Component.It runs fine when run on local.
    But when i put it on portal, navigation does not work.the control is not transferred to the method of backing bean.It is not showing loggers either.
    jdev version :10.1.3.3
    oracle portal :10.1.4
    Standalone OC4j : 10.1.3
    If any one has working model of this, can you pls post the files used.
    Also , if anyone has work around for same, it will be helpful.Thanks.

  • Help Building Simple Web Application

    So i've decided to build an online football pool application. I've decided its going to be built in java. I have spent some time going through java tutorials and learning what i can on my own.
    I've decided to use Apache Tomcat 4.1 as my web server and jsp/servlet engine. I know i am going to also use SQL Server as my database (i was able to get my hands on a copy)
    I want to separate my presentation logic from business logic. I plan on implementing my business logic using java beans that will reside in the web-inf/classes directory of my Tomcat directory.
    1) Am I headed in the right direction?
    2) Does anyone know of a good hands on book/web site that describes building a web application from the ground up using a similar architecture as described above. I have a lot to learn about java as well but prefer to learn it hands on.
    I appreciate any and all feedback.

    some interesting links...

  • Buling a new Web Application using JSF and Ajax.

    Hello Group,
    I am a building a new web application using JSF and AJAX. Planning to use Myfaces Tomahawk, Dojo for Ajax, Hibernate, Spring,Eclipse IDE and Jetty Server.Can some one please suggest me will this be a right one for
    building complex UI and will it support for using the jsf features and would like to know any other free open
    source framework, ide, tools which support the best way for an agile project..?. There is restriction like i have to use java1.4

    Hello Friends,
    I am also in the same situation.
    I am a building a new web application using JSF and AJAX.
    Requirement is I need to use IBM version of DOJO and JSF but I need to develop the whole application using Eclipse 3.3,2 and Tomcat 5.5.
    With IBM version of DOJO and JSF, will Eclipse and Tomcat help to speed up the development or do you suggest me to go for Rational Application Developer and WebSphere Application Server.
    If I need to go with RAD and WAS, then I am new to RAD and WAS, is it easy to use RAD and WAS for this kind of application and implement web applicaiton fast.
    Any feedback will be great help.Those don't sound like requirements of the system to me. They sound more like someone wants to improve their CV/resume
    From what I've read recently, if it's just fast you want, look at Ruby on Rails

  • Problem with Configuring Tomcat for running jsp web applications..Plz HELP

    I am using Tomcat 5.5 and Jdk 1.5.0_12 and Oracle 10g. I am using jdbc-odbc bridge connection
    to connect to the database. I have placed my project folder called
    tdm under the webapps folder in Tomcat. This 'tdm' folder consists of
    a collection of html pages,jsp pages and images of my project. Also I created a
    WEB-INF folderand in that I have lib folder which contains catalina-root.jar
    , classes12.jar and nls_charset.jar files. And also in the WEB-INF folder I have the web.xml
    file which looks like this

    By defining this element, means that every manager will be changed.
    So when running a cluster, only make sure that you have webapps in there
    that need to be clustered and remove the other ones.
    A cluster has the following parameters:
    className = the fully qualified name of the cluster class
    name = a descriptive name for your cluster, can be anything
    mcastAddr = the multicast address, has to be the same for all the nodes
    mcastPort = the multicast port, has to be the same for all the nodes
    mcastBindAddr = bind the multicast socket to a specific address
    mcastTTL = the multicast TTL if you want to limit your broadcast
    mcastSoTimeout = the multicast readtimeout
    mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
    mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
    tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
    tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
    in case of multiple ethernet cards.
    auto means that address becomes
    InetAddress.getLocalHost().getHostAddress()
    tcpListenPort = the tcp listen port
    tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
    has a wakup bug in java.nio. Set to 0 for no timeout
    printToScreen = true means that managers will also print to std.out
    expireSessionsOnShutdown = true means that
    useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
    false means to replicate the session after each request.
    false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)
    <%
    HashMap map = (HashMap)session.getAttribute("map");
    map.put("key","value");
    %>
    replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
    * Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
    * Synchronous means that the thread that executes the request, is also the
    thread the replicates the data to the other nodes, and will not return until all
    nodes have received the information.
    * Asynchronous means that there is a specific 'sender' thread for each cluster node,
    so the request thread will queue the replication request into a "smart" queue,
    and then return to the client.
    The "smart" queue is a queue where when a session is added to the queue, and the same session
    already exists in the queue from a previous request, that session will be replaced
    in the queue instead of replicating two requests. This almost never happens, unless there is a
    large network delay.
    -->
    <!--
    When configuring for clustering, you also add in a valve to catch all the requests
    coming in, at the end of the request, the session may or may not be replicated.
    A session is replicated if and only if all the conditions are met:
    1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
    2. a session exists (has been created)
    3. the request is not trapped by the "filter" attribute
    The filter attribute is to filter out requests that could not modify the session,
    hence we don't replicate the session after the end of this request.
    The filter is negative, ie, anything you put in the filter, you mean to filter out,
    ie, no replication will be done on requests that match one of the filters.
    The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
    filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
    ending with .gif and .js are intercepted.
    The deployer element can be used to deploy apps cluster wide.
    Currently the deployment only deploys/undeploys to working members in the cluster
    so no WARs are copied upons startup of a broken node.
    The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
    When a new war file is added the war gets deployed to the local instance,
    and then deployed to the other instances in the cluster.
    When a war file is deleted from the watchDir the war is undeployed locally
    and cluster wide

    in a browser. Here I accept a username and password from the user and then do the validation in
    a valid.jsp file, where I connect to the database and check and use jsp:forward to go to next pages
    accordingly. However when I enter the username and password and click Go in the homepage, nothing is
    displayed on the next page. The URL in the browser says valid.jsp but a blank screen appears.
    WHY DOES IT HAPPEN SO? DOES IT MEAN THAT TOMCAT IS NOT RECOGNIZING JAVA IN MY SYSTEM OR IS IT A PROBLEM
    WITH THE DATABASE CONNECTION OR SOMETHING ELSE? I FEEL THAT TOMCAT IS NOT EXECUTING JSP COMMANDS?
    IS IT POSSIBLE?WHY WILL THIS HAPPEN?
    I set the JAVA_HOME and CATALINA_HOME environment to the jdk and tomcat folders resp.
    Is there any other thing that I need to set in classpath? Should I have my project as a
    WAR file in the webapps of TOMCAT or just a folder i.e. directory structure will fine?

    <!-- Defines a cluster for this node,
    By defining this element, means that every manager will be changed.
    So when running a cluster, only make sure that you have webapps in there
    that need to be clustered and remove the other ones.
    A cluster has the following parameters:
    className = the fully qualified name of the cluster class
    name = a descriptive name for your cluster, can be anything
    mcastAddr = the multicast address, has to be the same for all the nodes
    mcastPort = the multicast port, has to be the same for all the nodes
    mcastBindAddr = bind the multicast socket to a specific address
    mcastTTL = the multicast TTL if you want to limit your broadcast
    mcastSoTimeout = the multicast readtimeout
    mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
    mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
    tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
    tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
    in case of multiple ethernet cards.
    auto means that address becomes
    InetAddress.getLocalHost().getHostAddress()
    tcpListenPort = the tcp listen port
    tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
    has a wakup bug in java.nio. Set to 0 for no timeout
    printToScreen = true means that managers will also print to std.out
    expireSessionsOnShutdown = true means that
    useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
    false means to replicate the session after each request.
    false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)
    <%
    HashMap map = (HashMap)session.getAttribute("map");
    map.put("key","value");
    %>
    replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
    * Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
    * Synchronous means that the thread that executes the request, is also the
    thread the replicates the data to the other nodes, and will not return until all
    nodes have received the information.
    * Asynchronous means that there is a specific 'sender' thread for each cluster node,
    so the request thread will queue the replication request into a "smart" queue,
    and then return to the client.
    The "smart" queue is a queue where when a session is added to the queue, and the same session
    already exists in the queue from a previous request, that session will be replaced
    in the queue instead of replicating two requests. This almost never happens, unless there is a
    large network delay.
    -->
    <!--
    When configuring for clustering, you also add in a valve to catch all the requests
    coming in, at the end of the request, the session may or may not be replicated.
    A session is replicated if and only if all the conditions are met:
    1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
    2. a session exists (has been created)
    3. the request is not trapped by the "filter" attribute
    The filter attribute is to filter out requests that could not modify the session,
    hence we don't replicate the session after the end of this request.
    The filter is negative, ie, anything you put in the filter, you mean to filter out,
    ie, no replication will be done on requests that match one of the filters.
    The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
    filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
    ending with .gif and .js are intercepted.
    The deployer element can be used to deploy apps cluster wide.
    Currently the deployment only deploys/undeploys to working members in the cluster
    so no WARs are copied upons startup of a broken node.
    The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
    When a new war file is added the war gets deployed to the local instance,
    and then deployed to the other instances in the cluster.
    When a war file is deleted from the watchDir the war is undeployed locally
    and cluster wide

    I have set the context path to /tdm in the server.xml file. Should this be placed in context.xml?
    My first page in the project is called Homepage.html. To start my project I give http://localhost:5050/tdm/homepage.html
    in a browser. Here I accept a username and password from the user and then do the validation in
    a valid.jsp file, where I connect to the database and check and use jsp:forward to go to next pages
    accordingly. However when I enter the username and password and click Go in the homepage, nothing is
    displayed on the next page. The URL in the browser says valid.jsp but a blank screen appears.
    WHY DOES IT HAPPEN SO? DOES IT MEAN THAT TOMCAT IS NOT RECOGNIZING JAVA IN MY SYSTEM OR IS IT A PROBLEM
    WITH THE DATABASE CONNECTION OR SOMETHING ELSE? I FEEL THAT TOMCAT IS NOT EXECUTING JSP COMMANDS?
    IS IT POSSIBLE?WHY WILL THIS HAPPEN?
    I set the JAVA_HOME and CATALINA_HOME environment to the jdk and tomcat folders resp.
    Is there any other thing that I need to set in classpath? Should I have my project as a
    WAR file in the webapps of TOMCAT or just a folder i.e. directory structure will fine?

  • Arabic text in my web application using iText..

Also an honorable way to make money IMO.I was using iText before 2004 when the first edition of the book came out ( 4 years or so after the library was first introduced) and it was hard work. PDF is a very complex document format and just using the Javadoc does not really get you anywhere. There are many 'gotchas' in iText and most of the iText tutorials cover only the very basics and pretty much none of the 'gochas'. The book starts off with very simple examples that could be constructed from the Javadoc but then it does move on to the more complex issues. Worth every penny.
