How to realize timeout while invoking a method in remote sesssion bean using my session bean running on wls5.1

I am using WL5.1 SP11 on a project. I have a stateless session bean inside which
I will invoke a method defined in another stateless session bean in a remote weblogic
server 5.1. The performance of the remote server is very low and sometimes when
I invoke the method through RMI, I got to wait for a long time. So I want to set
a timeout for my session bean while doing RMI call. The only parameter I could
find in weblogic-ejb-jar.xml is the "transaction-timeout", but even if I set transaction
attribute for my session bean, it always block there to wait for the response
from the remote session bean. The configuation did not work.
Is there any other solutions to my problem? Please give me some advice if anyone
has experience on it, Thank you very much.

How to achieve Entity Bean methods ONLY by calling them from a Session Bean

Hi,
I used a session bean as a business facade to a entity bean.
In the session bean I achieve the entity bean with a jndiContext.lookup("java:comp/env/ejbEntityBean").
Now I am looking for a solution that it is only possible to call the entity bean methods or the whole entity bean from the corresponding session bean.
In other words: "How can I forbid the access to the entity bean, if the calling object is not the corresponding session bean?"
--->
I only found a way the regulate the access to the entity bean methods by declaring a security-role.
But the existence of the security-role at runtime depends on the calling user-authorizations!
Is there a way to set the entity-security-role within the session bean context?
Best Regards
Steffen

Hi Srikanth Reddy.T,
sorry, I am not looking for a special tag <entity-security-role>.
I am looking for a way to specifiy that my session bean "has" the special security-role (in my case "WebZaehlerEjbRole") of my entity bean "in my case "WebZaehlerEjbRole") that is necessary to call the methods (findAlleEntries, findByWindowId,...) of my entity-bean.
Here is the relevant part of my ejb-jar.ml:
     <assembly-descriptor>
          <security-role>
               <role-name>WebZaehlerEjbRole</role-name>
          </security-role>
          <method-permission>
               <description>method-permission</description>
               <role-name>WebZaehlerEjbRole</role-name>
               <method>
                    <ejb-name>WebZaehlerBean</ejb-name>
                    <method-name>findAllEntries</method-name>
                    <method-params/>
               </method>
               <method>
                    <ejb-name>WebZaehlerBean</ejb-name>
                    <method-name>findByWindowId</method-name>
                    <method-params>
                         <method-param>java.lang.Long</method-param>
                    </method-params>

Problem while invoking webservice-method in client-code

Hi,
I had written webservice-client-code (using uddi-ext.jar, as i am using uddi for publishing webservices.) which is invoking webservice method successfully with complex datatypes(both for return type and input paramters).
But while calling following webservice-method from my client-code:
public ComplexType[] getData(String[] p_str1, String[] p_str2)
it is throwing exception
The Exception is:
[ERROR] - 27 Mar 2007 12:34:38 -failed to invoke operation 'getData' due to an error in the soap layer (SAAJ); nested exception is: Message[failed to deserialize xml:weblogic.xml.schema.binding.DeserializationException: mapping lookup failure. type=['java:language_builtins.lang']:ArrayOfString schema context=TypedSchemaContext{javaType=[Ljava.lang.String;}]
Although I had done correct registration of mapping of ArrayOfString in client-code:
registry = m_Service.getTypeMappingRegistry();
m_TypeMapping = registry.getTypeMapping(SOAPConstants.URI_NS_SOAP_ENCODING );
m_TypeMapping.register( ArrayOfStringHolder.class,
new QName( "java:language_builtins.lang", "ArrayOfString" ),
new ArrayOfStringCodec(),
new ArrayOfStringCodec());
But some how it doesnt works.
I had searched on google as well but didnt find any reliable solutions.
Please advice.

Error while invoking ContactQueryPage method from contact.wsdl

Hi All,
Could any one provide me the java client for OnDemand webservice (contact.wsdl). I want to query ContactQueryPage operation.
I am facing some problem while making a call. I am trying with both Axis call as well as ContactStub. but its not working in either way.
Here is the snnipet I am using to invoke a method using ContactStub

Can any one help me out. Its needed urgently.

Hi !
From what I see, the only problem is the setUseChildAnd function which is waiting for a true or false argument and not a char...
Hope this will help, feel free to ask more !

How to use a session bean in another session bean (or an EJB in a session)

JDev 11.1.1.4, WLS 10.3.4, Windows 7 x64
I have a login controller with a session-scoped bean that manages logins.
I have another session-scoped bean that manages menu security.
both modules compile and work fine now I need to share the data from one to another.
I need to reference the login controller in the menu security bean. How do I reference (include) the login bean in the security bean?
I tried an EJB - what a farce - these are supposed to be universal and easy ( basis of the oop in Java).
the bean is defined:
@Stateless(name = "SecurityEJB", mappedName = "ZITASApplication-ZITASModel-SecurityEJB")
I have tried :
ic = new InitialContext();
session = (SecurityEJBLocal)ic.lookup("ZITASApplication-ZITASModel-SecurityEJB#model.security.logic.SecurityEJB");
session = (SecurityEJBLocal)ic.lookup("ZITASApplication-ZITASModel-SecurityEJB#model.security.logic.SecurityEJBLocal");
session = (SecurityEJBLocal)ic.lookup("java:ejb/model.security.logic.SecurityEJB");
session = (SecurityEJBLocal)ic.lookup("java:ejb/SecurityEJB");
session = (SecurityEJBLocal)ic.lookup("java:app/SecurityEJB");
session = (SecurityEJBLocal)ic.lookup("java:module/SecurityEJB");
All return null pointers and claim the name cannot be resolved.
As you can see - I have found various claims to how to do this.
One way says create a sevlet, generate a listener and use the sevlet. Basically one for every EJB - a lot of work to use the EJBs
I would assume that this would be one of the easiest parts of java - as it is the foundation of re-usability and oop.
I can do either in the application - the added complexity of the EJB is less desirable - but better programming?

Hi,
ic.lookup("ZITASApplication-ZITASModel-SecurityEJB#model.security.logic.SecurityEJB");This should work with remote interface. If you want to lookup local interface, you need to register it in web.xml. Quote:
To access the business local interface you need to define ejb local references for your component environment (i.e. from your servlet environment). You can do this by defining references in your web.xml. For example:
<ejb-local-ref>
<ejb-ref-name>ejb/BusinessLogicBean</ejb-ref-name>
<local>packagename.BusinessLogicBean</local>
</ejb-local-ref>
To lookup your local reference from your servlet you need to use the following JNDI reference:
java:comp/env/ejb/BusinessLogicBean Another one
First, declare a local ejb reference in your web.xml file (This will add it to JNDI):
<ejb-local-ref>
<ejb-ref-name>ejb/Foo</ejb-ref-name>
<local>simple.ejb.FooLocal</local>
</ejb-local-ref>
Then it can be looked up from JNDI:
InitialContext ctx = new InitialContext();
FooLocal foo = ctx.lookup("java:comp/env/ejb/Foo");Hope this helps.

Problem with getting Entity Beans refreshed within Session bean methods

I hav following code in session and entity beans:
Session bean pseudo code: (PrimaryKey is primary key class for the entity
bean referred here, and MySessionHome is the home interfac class for this
session bean).
public class MySession implements SessionBean {
// This method is present in remote interface class as well.
public void methodA(PrimaryKey pk) {
// code to find entity bean by primary key specified.
update the entity bean, and mark it as isModified.
public void methodB(PrimaryKey pk) {
// code to find entity bean by primary key specified.
do something.
public void methodC() {
MySessionHome sessHome = code to lookup sessionhome from JNDI.
MySessionRI sess = sessHome.create(); // MySessionRI is the remote
interface class for MySession
PrimaryKey pk = new PrimaryKey(params);
sess.methodA(); // LINE ABC1
sess.methodB(); // LINE ABC2
all the entity and session bean methods have required as the TX attribute.
In methodB() on LINE ABC2, the entity bean obtained by findByPrimaryKey does
not reflect the changes made in call to methodA() on LINE ABC1.
Now if I change the LINE ABC1 and LINE ABC2 to
methodA(); // LINE ABC1
methodB(); // LINE ABC2
in this case the entity bean obtained in methodB() has the changes made in
methodA().
Any idea why this is happening?

Hi ad13217 and thanks for reply.
I'm sorry but my code is like this:

arguments was an error on copy, but it doesn't work.

HTTP(S) Timeout while invoking WebService over HTTPS.

Hello,
I have some stress with my webservice client implementation.
I do the following (I can post source code if needed):
- As usual:
System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
- Install my TrustManager
- Install my DefaultHostnameVerifier
- Register a custom type
- Make a javax.xml.rpc.Call to access a webservice
My observations:
The code works well when using an HTTP URL, just changing the target URL to HTTPS causes the problem.
The HTTPS web service (on server) works well seeing a HTTPS client using the weblogic SSL implementation, or an AXIS client can easily connect.
When I use a simple and direct "Open HttpsURLConnection on URL("https://xxx.service?WSDL"); print-out-all-that's-coming-in", it works well. I think my SSL access is made correctly.
The client does not complain about not-installed SSL things, all certificates are accepted, etc. No problem at this part.
System.setProperty("javax.net.debug", "all") is set, but i dont see anything of interrest.
I use the packages contained in 'java_xml_pack-summer-02_01' of SUN (jaxm-1.1_01, jaxp-1.2_01,jaxr-1.0_02 etc and the jsse 1.0.3).
The server is weblogic 7.
Calling
call.setTargetEndpointAddress("http://arakis:7001/traces_ws/searchCertificate");
works well while
call.setTargetEndpointAddress("https://arakis:7002/traces_ws/searchCertificate");
causes (after 2 minutes):

What I note is that the call is using a HttpURLConnection object and NOT a HttpsURLConnection object (so problems are 'normal' i guess), but I dont have any clue what I have to do to instruct the client to use HTTPS other than specifying HTTPS in the target.
Hope someone has an idea
Tasha

Hello,
The default timeout in Axis is 60 seconds, you can change it by your client code, and you can still keep the session to call many times
((org.apache.axis.client.Stub)service).setMaintainSession(true); //keep session
((org.apache.axis.client.Stub)service).setTimeout(60*1000*30); //half hour

How to make decision while invoking SOA workflows

Hi,
I have a created a SOA composite. This SOA Composite contains 4 level of approval.
Now I want that the decision to execute the SOA composite approval process should be defined in some other file from where I can read the information and execute those level of approval.
For Eg. I want to check if the user org is A then get the value of approval levels from the flat file and then execute only those approval levels in Composite.
Please let me know if this is feasible and how to achieve this.
Thanks

Yes, I retrieve data from database. Retrieving invocation is placed in getValue method of model. When there is no value in cache then I request data from server and wait for response. Else I get data from cache immediatly and everything is fine.
And you were partially right. In cases where I use manual repaint there was call from EDT. I replaced it by new Thread(...) and it helped. But repaint can be done automatically by Swing when user for example scrolls JTable and in this case I have to wait in EDT while get something to display. In this situation it would be great if independent repaint for JProgressBar can occurr. :(

Because, there's no FTP client command that allows to do such thing.Socket.setSoTimeout().I agree with you on this one but the OP is talking about the FTPClient API from Apache.
To the OP,
BTW, I have reread the Javadoc about the [*API*|http://commons.apache.org/net/api/org/apache/commons/net/ftp/FTPClient.html] : indeed, there's no setTimeout method, but there is a setDataTimeout method : +Sets the timeout in milliseconds to use when reading from the data connection+ .

How to pass parameter to the method in EJB session bean from Managed Bean

Hi,
I need some guidance in accessing the EJB session bean methods from one of my backing Bean. I use EJB 3.0 Entity Beans and EJB Session Beans. I have to get value from my page and pass it thro the backing bean to the respective EJB session bean. I have no clue of how to do this,
When i click a command link on the page, in its backing bean click method, i am able to get a value and store in a variable under its click action. But from there i am not knowing of how to pass it as a variable to the EJB session bean and hence execute the query(this is where we have to pass the variable as a parameter in its where clause) in the entity bean.
I wanna know how to make a call to the EJB session bean and from there execute the Enitity bean.
Guide me regarding this....
Thanks
ri

Unfortunately dependency injection doesn't work for jsf backing beans, so you have to use a normal jndi lookup to find your session bean. The following example shows you how to find a session bean and call a method:
public void commandButton_actionListener(ActionEvent actionEvent) {
Context ctx;
try {
ctx = new InitialContext();
helloWorldEjb = (HelloWorldEJB)ctx.lookup("HelloWorldEJB");
hello = helloWorldEjb.sayHello(name);
System.out.println(hello);
} catch (NamingException e) {
e.printStackTrace();
}

How to pass value from EXIT to method

Hi friends
1) My requirement is that when the person change the amount field in TRIP t-code i need to send a mail to the manager. So i found a exit FIT0002 here when ever the traveler change the amount i am setting the flag as x when he change and y when no amount is changed in exit. I did export to memory id and in my method i did import from memory id. But this is not performing gud. If at a time many users apply the trip and changes the advance the flag is not getting set. I checked in the log. No flag is set its empty no x nor y. After clearing the buffer SWU_OBUF. Again all the users applied the trip then the flag is set and every manager got the mail. But why this is happening?. Is there any other way to achieve it. I want to get the flag value to my method. Is there any other work around.
2) I tried with SAP_WAPI_WRITE_CONTAINER directly getting the value and writing to the workflow container its not correct way since i need to write commit work. But the exit itself does commit.
3) I tried with SET/GET parameter but i don't no how to divert my flow from my method to exit when i use SET/GET parameters.
Can any one throw some light on this issue.

If you are able to get the workitem ID then try to use the below code snippet and check because even Iam setting some value back to the workitem container

      w_wiid      TYPE             sww_wiid     VALUE   'XXXX',
