Programmatic access to extend proxy from client

As a remote client of an extend proxy service, is there anyway I can get information about that service?
I'd be looking get access to the kind of details you see exposed by the mbeans via JMX
Many thanks

Access the object array from client.

I'm trying to access the object array from client.
it's throwing the following error,
RemoteException Ocuredjava.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.MarshalException: CORBA BAD_PARAM 0x4f4d0006 Maybe; nested exception is:

how to resolve it?
thanx in advance,

Don't send a ResultSet back as the result of an RMI call. Extract the data from the ResultSet on the server and send that back instead.

If this proxy design (not starting up due to a invalid entry in "authroized-hosts") is on-purpose from Coherence Engineers - then it should be re-visited.
I think the PROXY Server should just log a message stating about the invalid DNS entry for the Authorized-host and continue with the startup...Failing to start completely doesn;t make sense since one cannot rely completely on DNS to
say everything should be correct before a server start.
Ofcourse you can overcome by writing your own Custom Filter - but the issue pop's out as with any custom filter(s) is maintaining them along the road (with all minor/major coherence upgrades).
Also - this "Authorized-Hosts" concept should be carefully analyzed particularly for the following issues...
(1) if the client IP is changed in the DNS server - will the proxy-server allow the new Client connection without any issues? when will the PROXY server flush its CLIENT DNS entries or what is the TTL time-limit for a CLIENT cached through Authorized-hosts by the PROXY-SERVER?
(2) Suppose, we have a CLIENT in the "Authroized-Hosts" making a valid connection to the PROXY and putting some cache into the SERVER CACHE through the PROXY....now if the IP-address (DNS being the same) of the CLIENT is changed - can the CLIENT can GET the CACHE it just PUT into the SERVER without any ERRORS?
(3) How often we need to re-start PROXIES? Do we need to re-start them often for the DNS issues (if any) mentioned above?
Looks like the Limited documentation & examples for Coherence*Extend - particularly for .NET & C++ clients & *Extend Proxies is a point of concern.

Cannot load Java plug-in and access R12 Oracle form from client

Hi, one of my user cannot open Oracle form when accessing R12 environment using IE6. After selecting responsibility and menu, it got stuck after 50% processing when trying to load Java applet. It never got completed even after waiting for 2-3 hours.
Is there any browser setting that needs to be modified? I checked popup blocker and activeX setting. All seem to be in order. Kindly assist. Thanks.

Hi,
What is the difference between this client and other clients?
Delete the browser cache/history files and check then. If this does not help, enable trace for JRE (as per Note: 549423.1 - How to enable tracing and logging for Sun JRE (Native Plug-in)) and see if it shows any errors when you encounter this issue.

Hussein

I am using Tomcat 5.0.19 . Could anyone suggest a possible solution to the same?
The system works fine when I use a http endpoint.

Hi,
By default, your application tries to connect to the Net directly : if you have to specify a proxy, use either these lines in your code :
System.setProperty("http.proxySet", "true");
System.setProperty("http.proxyHost", "proxy");
System.setProperty("http.proxyPort", "8080");
Or specify them in the command line with the "-D"option.
Ex : java .... -Dhttp.proxySet=true .... MyApp
Hope it helps.

Access denied while loading jar files from client

I am creating a platform
that can be started by JWS
and then load plug-ins from client drive.
I've signed my platform (packaged as a jar file),
and set up the security tag in my jnlp,
so that it can access client files.
The plug-ins are packaged as jar files.
And in one of the plug-ins, there is a class that has a JFileChooser field.
While initializing this field, the AccessControlException is thrown.
I can't figure out what is wrong,
So I tried to sign the plug-in, but the problem stands still.
PS. I have made my own ClassLoader,
and this platform works well without JWS.
Please help me, thanks.

When running under Java Web Start, a security manager is installed.
Since you have created your own classloader, you are responsible for assigning permissions to the classes you load.
You can change you class loader to extend SecureClassLoader, then override getPermissions:
protected PermissionCollection getPermissions(CodeSource codesource) {
PermissionCollection perms = super.getPermissions(codesource);
/* add whatever permissions you want your code to hance*/
perms.add( ... );
/* or just add all-permissions */
perms.add(new AllPermission());
or - you can just remove the Security Manager:
System.setSecurityManager(null);

Exchange 2013 - Proxy through client access server not working

Hello All -
I recently migrated our company to Exchange 2013 and noticed that our email was leaving through the mailbox server. I put a check mark in the Send Connector where it says "Proxy through Client Access Server" and my mail is still coming from the
mailbox server. How can I go about fixing this problem?
Environment:
1 CAS Server
1 Mailbox Server
Both server are behind the firewall with only port 25 opened to the CAS. The CAS has a Send Connector to a smart host for all messages.
Thank you!
Ryan

Hi,
Please check if the outbound messages without smart host are coming from CAS .
I doubt it send to the smart host directly if you configure smart host, and not use proxy thogh CAS.

Unable to access LAN behind RV042 from QUICK VPN Client once it connects

Hi,
Very recently, we had implemented Site-to-Site VPN tunnel between two Linksys RV042 4-port VPN routers. Everybody in our remote site is accessing and sharing the data through this tunnel and it is working fine.
Now, we have a plan to implement the same for our mobile clients also. For this, we had followed all the basic configuration procedures and user got connected to Quick VPN tunnel. Here is a problem we had observed. The mobile client user is connected to the tunnel, but unable to access the office LAN from the PC.
What's the problem in configuration? What i have to do?
Thanks

Hi There.

ABAP client proxy from WSDL

I have 2 problems in creating abap client proxies using wsdl
1.when i try to create client proxy by giving RPC style wsdl(generated by SAP itself for a RFC) the system throws an error and not allowing to create the proxy
2.The client proxy which i have created for a wsdl(either SAP created document type/any wsdl from commercial websites) gives an error "No receiver could be found"
could somebody please clarify and help me to solve the problem.
Thanks in advance.

Dynamic Configuration from Client ABAP Proxy

Hello Experts,
Is it possible somehow to set Dynamic Configuration values to Message Header when calling Client ABAP Proxy from SAP system?
Best Regards

I managed to get the dynamic header configuration at least with inbound proxies:
    DATA:
        server_context TYPE REF TO if_ws_server_context,
        proxy_framework TYPE REF TO if_proxy_framework,
        internal_protocol TYPE REF TO if_wsprotocol_internal,
        lo_inb_pxy TYPE REF TO cl_xms_inbound_proxy_plsrv,
        lo_dyn_header TYPE REF TO if_xms_msghdr30_dynamic.
      server_context = cl_proxy_access=>get_server_context( ).
      internal_protocol ?= server_context->get_protocol( 'INTERNAL' ).
      lo_inb_pxy ?= internal_protocol->get_framework( ).
      lo_dyn_header ?= lo_inb_pxy->xmb_message->get_dynamic_header( ).

Not getting response from Client Proxy

Hi,
We are developing a scenario - File->PI->Proxy using ABAP Proxies.We are posting a file thru PI 7.0 to R/3 .In R/3 the server proxy(Inbound Asynchronous) will receive the message and BAPI will be called. The response from the BAPI will be reaching the server proxy and passed to the client proxy(Outbound Asynchronous).
Server Proxy(request) --> BAPI --> Server Proxy(response) --> Client Proxy(response)
The response from the client proxy has to be send to PI and a file will be generated as the output.
Can anyone provide me suggestions to call client proxy from a server proxy by passing the response message to client proxy???
Thanks in advance.
Regards,
Dibyajyoti

Hi,
I hope, you are done till the Implementation of Server Proxy, where you are calling a Bapi and passing the Input variables the Interface received and BAPI is giving a response back.
Now your question, how to send the response back Asynchronously.
I think, you have to do the same, what you do for a client proxy and at last call the method EXECUTE_ASYNCHRONOUS before the Final Commit Staement. I think this should work.
But using Synchronous Interface in such cases is always a handy and easier option.

Client proxy from user exit

I am invoking a client proxy from user exit (user exit is invoked in update task). Is there any red flags I need to be aware of.
Proxy takes a while to execute and till that time, My original document does not get updated.

Hi Kris,
If it gives u Timeout error then only data will not be posted and it will be an issue.
If data posted from proxy then check in SXMB_MONI in Ecc side.

Accessing apps from client GUI tool and TNS-12537

I have 11i on linux up and running but need to access the db via developer tool but I always get the error tht connection closed or connection lost.
I looked in the sqlnet.ora and it does has below entries
tcp.validnode_checking = yes
tcp.invited_nodes=(192.168.1.1)
Somewhere I read that I should add the ip of the host from where I am making clinet connection in the invited_nodes list.
Can someone please conform how to resolve this issue, The listener and db are up and I can logon locally on server vis sqlplus.

You need to register the hosts which you want to give SQL*Plus access as nodes.
From OAM, navigate to Site Map > Administration > System Configuration > Hosts > Register.
You may also comment "tcp.validnode_checking = yes" but this will allow any client to be able to connect to the Database.
For more details, please refer to Note: 291897.1 - 11.5.10 New Features : Managed SQL*Net Access from Hosts

Unable to access E1 instance from client

Hi All,
Urgency:Yes
Version: E 8.12 Stand alone Demo
I am trying to install JDE E8.12 Stand Alone on a desktop.It's installed and when I click on +'Tools->EnterpriseOne Menu'+ submenu,it redirects me to :'http://localhost:8888/jde/E1Menu.maf' and I can see the home page of E1.
Now I am trying to access the above url from a laptop(basically with the idea that desktop will be a server and laptop as client) by replacing 'localhost' with the IP of the desktop.
I am unable to get the login page with any of thr browsers.
It says: **'The page cannot be displayed'**.
Can anyone let me know what other settings should be done on the desktop or on laptop(client),so that I can access it from my laptop,as E1 being Web-based application.
Any guide on Stand alone installation will be highly appreciated.
Regards,
Nikesh.

Hi Murali,
Many thanks for your instant reply.
But when I do the same installation on my laptop,other laptops(who are in the same network) are able to access it and thus the E1 installed on my laptop becomes server.
Meanwhile can you let me know where shall I get a hang of 'OTM-E1' integration.Any supporting guide from E1 side ,if you have,please share.
I read that we would need 'E1 servlet installation instructions' guide.
Thanks.
Regards,
Nikesh.
