Spring HTTP INVOKERs

hi
this is vinod
in my project we are going to use the spring httpinvoker to interact with database daos
to map the swing gui
how it is used can u please provide the simple code for that any body
how the code will be..

Why is someone else going to write your code for you? Spring is pretty well-documented, between the official docs, the numerous books and the abundance of tutorials on the 'net. These "I've had this great idea, can someone else actually do the work?" questions are getting really irritating.

Spring and TopLink/JPA on OC4J 10.1.3.4.0

Our configuration worked fine on OC4J 10.1.3.1 (linux) and 10.1.3.3 (windows). We have a problem with JPA (toplink essentials--not eclipselink) on OC4J 10.1.3.4.0 using Spring (2.0.7 and 2.5.6). We found that it was trying to connect to the default OracleDS data source(there were 2 connections in toplink essentials for some reason), but once we defined an OracleDS, it gave us this error:
javax.servlet.ServletException: javax.faces.el.EvaluationException: Error getting property 'experiments' from bean of type gov.llnl.nif.dataviz.mssar.web.ExperimentListBean: org.springframework.transaction.CannotCreateTransactionException: Could not open JPA EntityManager for transaction; nested exception is java.lang.IllegalStateException:

We also had this problem. We have changed the TransactionManager.
Replace the JPATransactionManager with the JTATransactionManager.
<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager" />
If you are using JTA you can't use the JPA Transaction Manager. It doesn't support JTA.
Found it on a forum of Spring. (http://forum.springframework.org/showthread.php?t=48191)

Weblogic 10.3TP, JAX-WS and Spring integration

Hi all
We are using JAX-WS and Spring (2.0.6) and our target platform will be Weblogic 10.3. We would like to benefit from Spring injection in our web service classes. However I cannot get it to work. I follow the instructions described here: [url https://jax-ws-commons.dev.java.net/spring]https://jax-ws-commons.dev.java.net/spring and I use version 1.7 of jaxws-spring
When deploying the sample project I get the following error:
2007-12-06 09:28:42,238 ERROR [org.springframework.web.context.ContextLoader] - Context initialization failed

...It sounds like JAX-WS - Spring integration is not supported in Weblogic 10.3TP.
Has anyone been able to get the sample project working?
Does anyone know if the final version of Weblogic 10.3 will have JAX-WS Spring injection support?
Thanks
Dries

anybody can help?
thanks

Spring

Hello!
I have a jboss server and some web application using ejb, i was told to create a new webapp that would work separatley and use another database and to access my existing app from new one i need to use Spring, does anyone know a good tutorial or example how to do that?
Thanx

And their site has also specific pointers on how to access EJBs from Spring:
http://www.springframework.org/docs/reference/ejb.html

How do I completely enable a new custom asset in Correspondence Management?

Hello!
I'm trying to add a new custom asset to the Correspondence Management Solution Accelerator, and have it behave like all other assets in the system (ie searchable, updateable etc). I'm almost there, but there's obviously something I'm missing, and I was hoping someone here might have done this before, or have a link to some documentation regarding the matter that I may have missed. The asset I'm trying finish creating is for a LiveCycle user in a specific domain. This is what I've done so far...
I've created the asset definition MyUser.fml and placed it in the FSIApp\Portal\webapp\WEB-INF\assetDefinitions folder. I've then registered this fml file in the spring-config.xml file in both the 'lc.cm.assetDefinitionsDeployer' and 'lc.cm.assetTypeRegistryBootstrapper' beans. In the 'lc.cm.assetTypeRegistryBootstrapper' bean, I set the key to 'MyUser', and the value to the class path of my Java class that represents this asset.
On the Java side I've created the MyUser.java class, as well as MyUserService.java and MyUserServiceImpl.java to allow the searching, updating etc of the MyUser assets.
After running the Bootstrap process, I can log into the Manage Templates application, select Data Dictionaries from the 'View' dropdown, and view/edit the MyUser data dictionary properties with no problems. So I'm happy that the asset has successfully been registered with the application.
Where I'm stuck is choosing the MyUser asset from the drop down, and searching the system for assets of that type. I can choose the MyUser asset type from the 'view' drop down, but the search result returns an empty array.
From digging into the existing Manage Templates code, I've created the following classes:
public interface IMyUserService extends IEventDispatcher - containing the following function definitions:
          function getMyUser(id:String):IAsyncToken;
          function getAllMyUsers(param1:Query=null):IAsyncToken;
public class MyUserSeviceProvider extends ServiceProvider - containing a getter/setter for MyUserServiceDelegate
public class MyUserServiceDelegate extends ServiceDelegate implements IMyUserService - containing the functions defined in IMyUserService, as well as creating the RemoteObject to perform the actions.
The MyUserServiceDelegate constructor is:
     public function MyUserServiceDelegate ()
            super();
            _service = new RemoteObject("myapplication.services.myUserService");
            _service.showBusyCursor = true;
This is the code for the function in getAllMyUsers in MyUserServiceDelegate:
     public function getAllMyUsers(param1:Query = null):IAsyncToken
            var operationToken:AsyncToken = this._service.getAllMyUsers(param1);
            var token:IccToken = new IccToken(this.className + ".getAllMyUsers");
            operationToken.addResponder(getDefaultResponder(token));
            return token;
I've also made changes to the following config files to register the RemoteObject destination specified in the MyUserServiceDelegate constructor:
spring-http-config.xml:
     <bean name="/service/UserService" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
        <property name="service" ref="myapplication.services.myUserService" />
        <property name="serviceInterface" value="com.mydomain.lc.services.MyUserService" />
    </bean>
remoting-config.xml:
     <destination id="myapplication.services.myUserService"/>
flexmessagebroker-servlet.xml
     <flex:remoting-destination ref="myapplication.services.myUserService" />
Above my Java class definition of MyUserServiceImpl.java I have the following line:
@Service("myapplication.services.myUserService")
So......
My problem is that when I choose the MyUser asset from the drop down, no search results are returned (an empty array is returned). I have logging code in the getAllMyUsers function in the MyUserServiceDelegateclass.as, as well as logging in the MyUserServiceImpl.java class (not shown in the above code snippets) and neither of them fire when selecting the MyUser asset from the drop down. So neither of the classes are being called on the search. If I force a search via the following line:
MyUserSeviceProvider.getMyUserService().getAllMyUsers();
the logging in both the Flex and Java classes works (and the java class returns the results as expected). So I'm happy that these functions, as well as the linking between the Flex and the Java side is working correctly.
The step that I can't seem to work out is having the selection of the asset in the drop down call the desired function automagically. I've been digging into the SearchManager, the ServiceLocator and heaps of other classes, but I'm falling deeper and deeper into the rabbit hole...
Can anyone shed some light on what they think might be needed to make the final link here? I've been digging and digging into the code for days now and my brain hurts!!
Any advice appreciated!!
Thanks,
Kristian

Hi Saket,
By 'not really complete' I'm assuming (hoping) that some work has been done on this already. Our project requires the use of custom assets, so it's very important that we get this functionality running as soon as possible.
Any help, unsupported or otherwise, would be great. Feel free to email me any details if you'd prefer not to post anything public on the boards.
Cheers,
Kristian

New features, fewer interruptions
Whether you're browsing for fun or work (or even for fun while at work), you don't want unnecessary interruptions slowing you down or getting in the way of what you're doing. That's what the latest features in Firefox are all about: to give you a more seamless browsing experience.
Here are the latest changes we made to make browsing better:
* Private Browsing
We've had lots of requests for this one: Now you can open a Private Browsing window without closing your current session.
https://support.mozilla.org/kb/private-browsing-browse-web-without-saving-info
* Downloads
Never search for your download window again. Monitor your download progress right from the toolbar.
https://support.mozilla.org/kb/find-and-manage-downloaded-files
* PDFs
Rather than downloading PDFs and hunting for them on your computer, you can view them directly in your browser window.

Getting Open MQ and Mule 2.0 work together

Hi!
I would like to ask some help on getting Open MQ work with Mule 2.0. I'm quite new to both technologies, and I can't get them to work together. Here is how I've tried so far:
What I'm trying to achieve first, is that there are 2 queues in my open mq, and if something arrives in one queue, mule should get that from the queue and put it in the other queue.
I've created a configuration file for mule:
(sorry that it looks really crappy, for some reason, couldn't really get it to show nicely on this forum, however I edited it, it always made each line start on the left)
<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns="http://www.mulesource.org/schema/mule/core/2.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jms="http://www.mulesource.org/schema/mule/jms/2.0"
xmlns:spring="http://www.springframework.org/schema/beans">

<model name="JMSProba">
<service name="JMS">
<inbound>
<jms:inbound-endpoint queue="MyQueue" synchronous="false"/>
</inbound>
<component class="disp.Dispatcher"/>
<outbound>
<outbound-pass-through-router>
<jms:outbound-endpoint queue="out"/>
</outbound-pass-through-router>
</outbound>
</service>
</model>
</mule>
The service component class pretty much doesn't do anything for now, but is like this:
package disp;
public class Dispatcher {
public Object dispatch(Object o){
return o;
I'm using the Mule IDE, and unfortunately I can't even test if this works or not, because when it starts the mule server, I get an error, which I don't understand why I get:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'mule'.
I really have no idea why I get this exception. Anyone knows what I did wrong in my configuration file? Also, can anyone tell me, if what I'm trying to do looks something like this, or I'm doing it all wrong? If anyone can help me get this all to work, I'd really appreciate it.
I haven't seen any info on how to configure the Open MQ Connector, so I'm not sure how to do it. I've tried this:
<connector name="jmsConnector" className="org.mule.providers.jms.JmsConnector">
<properties>
<property name="specification" value="1.1"/>
<property name="connectionFactoryJndiName" value="ConnectionFactory"/>
<property name="jndiInitialFactory" value="com.sun.jndi.fscontext.RefFSContextFactory"/>
<property name="jndiProviderUrl" value="file:///C:/Temp"/>
<property name="jndiDestinations" value="true"/>
<property name="forceJndiDestinations" value="true"/>
<map name="connectionFactoryProperties">
<property name="brokerURL" value="vm://localhost:7676"/>
</map>
</properties>
</connector>
but it doesn't work, the error tooltip says "Invalid content was found starting with element 'connector'", and then the next error is at the first 'property' element, saying "Invalid content was found starting with element 'property'. One of '{"http://www.springframework.org/schema/beans":entry}' is expected. "
Can someone please also help me with the connector creation? Since this had errors, I had to cut it out when trying to run my config file, that's why you can't see it in it.
My next step (if this would work) would be to use this on 2 different JMS's - Mule gets the message from a queue from a certain JMS, then sends it to the queue of a different JMS. Of course I can't start working on this until my first task works, but I was wondering, how to create 2 different connectors and then use different connector for each of the endpoints.
Thanks for any help in advance!

I have no idea why I get this exception :(
There are a few things I don't understand in your config file though:
-How come we don't have to specify the address where the broker is running? (like localhost:7676)
-In the spring bean called "context", why do you specifiy the Open MQ installation directory? I mean, why do you have to specify it?
-I don't understand everything in the file, so I might say something stupid now... but ... you have a spring bean called "context", and I don't see it used anywhere. Or do you have to have a spring bean called context? Or is this necessary at all?
About the Open MQ admin tool. Am I correct in assuming, that all you have to do, is create a Broker (and add destination to it), and create an Object Store and add connection factory to it (and optionally physical destination too ... although this is not necessary because if you create a destination and you don't make physical destination for it, then by default it will be created for it). This is what I did with Open MQ tool.
I was wondering if you could please give me your email address, would be easier to communicate over that, this forum seems a bit deserted anyway.
Thanks in advance!

Please Help me to Choose the best config to run forms on web

Hi,
I have started upgrading my application from Dev2000 1.3 to Dev2000 6i in order to deploy on web. I have few questions to ask
1. I need to know which config is the best & fast to run my applications out of
     1. Applet
     2. IE50Native
     3. JInitiator
2. For testing I have configured forms server in socket mode. When I am using JInitiator even after exiting the application from test terminal, "ifweb60.exe" process initiated due to this session remains running. It takes long time when I try to initiate the same application for second time. This problem is not frequent, but this has happened 4 times while testing. Could this be due to Pentium4.
Thanks in advance

Currently im working on a web based user management application ( a small scale one ).
For that im hoping to use JSP s for presentaion tier and EJBs for business logic. This business logic seems to be having more on database accessing. Im not using Entity Beans for data access , but hope to use Session Beans.Why EJBs? POJOs will work just fine.
>
Is it ok if i develop according to this model , or is it better to use Entity Beans for data acccess ?Neither. Use POJOs. What are EJBs buying you?
Is it a bad design to use Session Beans for data accessing ?Why?
Or else , what if i avoid EJB s completely and database access is done via JSP itself ?Ouch, no. JSPs are for presentation only.
Or i have another option , that is , using JSP for the presentation layer and Servlets for database accessing.Wrong again.
what is the preferred way ? How i can decide a better way ?Learn how to layer an app properly. Learn Spring. http://www.springframework.org

How to fetch the data from databse table and get the required output

Hi,
I have made a project that connects CEP to database table but i m getting some problem in fetching the data from database.
From the following code :
If the where condition is removed then the application runs fine but i am still not able to fetch the data from the table because it is not showing any output.
Can anyone please suggest me that how to write WHERE statement correctly and how i will be able to see the output.

Kindly let me know if you need further info.

Do you have StockDs configured in your server config.xml?
I think the query should look more like this:
SELECT stocks.SYMBOL, stocks.EXCHANGE
FROM STOCK as stocks, ExchangeStream [Now] as datastream WHERE stocks.SYMBOL = datastream.SYMBOL

Action: Verify function or constructor for complex type exists, is not ambiguous, and has the correct
number of parameters.
I have made a user defined function in a java class and configured this function in the EPN assembly file under the processor tag.
But when i am trying to access the function in the config.xml file , it is giving me an error in the query.
Please provide urgent help that how to write the exact query.

Hi,
In the EPN Assembly file use
<bean class="com.bea.wlevs.example.FunctionCEP.TestFunction"/>
instead of
<bean>com.bea.wlevs.example.FunctionCEP.TestFunction</bean>

Exception raised while trying to join Table and Stream

I have written a sample Project to fetch the data from a Table and join it with the Input Stream. Followed the same procedure specified at http://download.oracle.com/docs/cd/E17904_01/doc.1111/e14301/processorcql.htm#CIHCCADG
I am getting the exception:

Issue identified. The datatypes of the stream order id and the one from the tables differ.

How can I select events from two different channels?

Hi everybody, I have another question! :)
When processing events in config.xml, using a CQL sentence, Eclipse compiler doesn't allow me to select more than one event.
I paste here my app.context.xml and my config.xml:
app.context.xml:
<wlevs:event-type-repository>
<wlevs:event-type type-name="HorseEvent">
<wlevs:class>com.bea.wlevs.event.example.sevenhorses.HorseEvent</wlevs:class>
</wlevs:event-type>
<wlevs:event-type type-name="GunmanEvent">
<wlevs:class>com.bea.wlevs.event.example.sevenhorses.GunmanEvent</wlevs:class>
</wlevs:event-type>
</wlevs:event-type-repository>

<wlevs:adapter id="sevenhorsesAdapter" class="com.bea.wlevs.adapter.example.sevenhorses.SevenHorsesAdapter" >
<wlevs:instance-property name="messageHorse" value="I am the horse number: "/>
<wlevs:instance-property name="messageGunman" value="I am the gunman number: "/>
</wlevs:adapter>
<wlevs:channel id="horseInputChannel" event-type="HorseEvent" >
<wlevs:listener ref="sevenhorsesProcessor"/>
<wlevs:source ref="sevenhorsesAdapter"/>
</wlevs:channel>
<wlevs:channel id="gunmanInputChannel" event-type="GunmanEvent" >
<wlevs:listener ref="sevenhorsesProcessor"/>
<wlevs:source ref="sevenhorsesAdapter"/>
</wlevs:channel>

<wlevs:processor id="sevenhorsesProcessor" />
<wlevs:channel id="horseOutputChannel" event-type="HorseEvent" advertise="true">
<wlevs:listener>
<bean class="com.bea.wlevs.example.sevenhorses.SevenHorsesBean"/>
</wlevs:listener>
<wlevs:source ref="sevenhorsesProcessor"/>
</wlevs:channel>
<wlevs:channel id="gunmanOutputChannel" event-type="GunmanEvent" advertise="true">
<wlevs:listener>
<bean class="com.bea.wlevs.example.sevenhorses.SevenHorsesBean"/>
</wlevs:listener>
<wlevs:source ref="sevenhorsesProcessor"/>
</wlevs:channel>
And here you are the two config.xml, I have tried two different ones and none of them runs.
The first one is:
<?xml version="1.0" encoding="UTF-8"?>
<n1:config xmlns:n1="http://www.bea.com/ns/wlevs/config/application">
<processor>
<name>sevenhorsesProcessor</name>
<rules>
<query id="horsesRule">
<![CDATA[ select * from horseInputChannel
        ]]>
</query>
<query id="gunmansRule">
<![CDATA[ select * from gunmanInputChannel
        ]]>
</query>
</rules>
</processor>
</n1:config>
As you can see, I use here TWO CQL sentences from the two channels that are defined in app.context.xml.
The other one is:
<?xml version="1.0" encoding="UTF-8"?>
<n1:config xmlns:n1="http://www.bea.com/ns/wlevs/config/application">
<processor>
<name>sevenhorsesProcessor</name>
<rules>
<query id="horsesRule">
<![CDATA[ select * from horseInputChannel, gunmanInputChannel
        ]]>
</query>
</rules>
</processor>
</n1:config>
I use here only ONE CQL sentence in which I try to get events from the two channels that are defined.
None of them works.
Can anybody help me?
Thank you!

Thanks in advance.

Hi Vikram,
I need some more help from your side.
It would be great help if you will let me know that how to extract the data from particular XML tag.
As of now i want to extract particular XML node by applying that query and the result i am getting is: <applicationID>Engage</applicationID>
I just want to know if I want to extract only data from this XML node i.e Engage instaed of *<applicationID>Engage</applicationID>*
Then what will be the query?
Thanks in Advance

Error: Invalid configuration for the JMS adapter

Hi!
I'm doing a test with CEP to get messages from a JMS WebLogic queue but I'm getting the following error:
<BEA-2045010> <The application context "Teste" could not be initialized: org.springframework.beans.FatalBeanException: Error in initialization context lifecycle; nested exception is java.lang.IllegalArgumentException: Invalid configuration for the JMS adapter, you must Bean or specify a converter or a type of event.

Please, what's wrong?
Thanks!

This error usually indicates that you have both event type and converter bean specified or neither specified. In your case, that doesn't appear to the case from looking at the spring file. Could you also paste the contents of your configuration file from META-INF/wlevs directory?
