Socks proxy call from a weblogic server across the firewall to an external program

Hi,
From our weblogic server, we are trying to connect to an external
program outside our firewall through SSL. The SSL connection is being
tunneled through a socks proxy in the DMZ. (We have not yet made it
work so far. Currently, we are trying to make it work)
From the weblogic bean, we are doing the following
System.setProperty("socksProxySet", "true");
System.setProperty("socksProxyHost", "w.x.y.z");
System.setProperty("socksProxyPort", "1080");
Not that weblogic bean is the initiator of the connection and it talks
to a program outside our firewall.
My question is, will this kind of system level setting in the weblogic
server have any negative impact? This is because, RMI is over sockets
and weblogic might be talking to its internal components through
sockets.
Is it advisable to have such socks related setting the weblogic bean
level?
thanks,
jas.

What the best way to call twenty tuxedo domains from one weblogic server use WTC

I need to call twenty tuxedo domains from one weblogic server use
WTC. the Service be called in the twenty tuxdo domains are same, do I need to
write twenty EJB in the weblogic server to call the same service? who have good
adea to deal with this problem?

Hi,
I have a question on the second case. When the client doesn't care of which
Tuxedo domain it is hitting. What happens if one of the Tux domain is down ? What
happens to the client request to that domain ?
Another question is lets say i have a Tuxedo configuration as MP mode( Multi
machine mode) how does WTC load balance between the Tuxedo domains.
Thanks,

Hi xcjing,
One way to handle your needs is to use local service name to remote
reservice name translation. For instance,
(in 6.1,6.0 WLS)
<T_DM_IMPORT ResourceName="TOUPPER1" LocalAccessPoint="WTC"
RemoteAccessPointList="TUX-DOM1">
     <RemoteName>TOUPPER</RemoteName>
</T_DM_IMPORT>
<T_DM_IMPORT ResourceName="TOUPPER2" LocalAccessPoint="WTC"
RemoteAccessPointList="TUX-DOM2">
     <RemoteName>TOUPPER</RemoteName>
</T_DM_IMPORT>
<T_DM_IMPORT ResourceName="TOUPPER3" LocalAccessPoint="WTC"
RemoteAccessPointList="TUX-DOM3">
     <RemoteName>TOUPPER</RemoteName>
</T_DM_IMPORT>
etc
With this configuration if your client have to call "TOUPPER" service
in
TUX-DOM1 then you code your client to call "TOUPPER1" and the request
will be routed to TUX-DOM1. The same way for request has to go to
TUX-DOM3, your client calls "TOUPPER3" service and WTC will route it
to
TUX-DOM3. In this remote name translation you may have to write 20 EJB
although they are almost the same. However, if your EJB can analyze
your client input to decide which Remote Tuxedo Domain to send the
service request to then you probably only need one EJB.
In the case that your client does not care which remote Tuxedo Domain
provides the service then adding
<T_DM_IMPORT ResourceName="TOLOWER" LocalAccessPoint="WTC"
RemoteAccessPointList="TUX-DOM1">
     <RemoteName>TOLOWER</RemoteName>
</T_DM_IMPORT>
<T_DM_IMPORT ResourceName="TOLOWER" LocalAccessPoint="WTC"
RemoteAccessPointList="TUX-DOM2">
     <RemoteName>TOLOWER</RemoteName>
</T_DM_IMPORT>
<T_DM_IMPORT ResourceName="TOLOWER" LocalAccessPoint="WTC"
RemoteAccessPointList="TUX-DOM3">
     <RemoteName>TOLOWEr</RemoteName>
</T_DM_IMPORT>
etc
Will load balance your client "TOLOWER" service request among your 20
remote Tuxedo Domain.
However, there is a bug in WTC that causes the Remote Service Name
translation functionality not working properly. It is fixed in the
upcoming release of WLS.

Thank you very much! But I still have question, give an example,
twenty Tuxedo domain is named domain1,domain2,....domain20. The
same Tuxedo Service: TOUPPER is deploy on those twenty Tuxedo domains,some time
I need call the TOUPPER Service on domain1,saome time I need call theTOUPPER
Service on domain3 or
other domain depend on the input from client. you mean I need to importThe TOUPPER
Service from twenty Tuxedo domains in the console,then write one EJBto call the
TOUPPER Service,but how can the EJB know which Tuxedo domain's TOUPPERto call
from?
Thank you!

hi xcjing,
You don't have to write 20 beans or deploy 20 beans because there
are
20
remote Tuxedo TDomain you need get the service from. Of course, WLSand
WTC does not prohibit you from doing it though. Whether you need20
beans or not depend more on you architecture.
To access 20 remote Tuxedo Domain from one single WLS with singleWTC
you can configure 20 remote Tuxedo Domain in the BDMCONFIG (6.1,6.0)
or
from the console (7.0). You import 20 services one from each remote
Tuxedo domain. You write one bean, and deploy one bean. Your WLS
clients will be able to access THE ejb, the EJB will access the WTC
service, and WTC will load balanced the service requests among the20
remote Tuxedo Domain.

Can not programmatically undeploy the application from a Weblogic Server

Hi experts,
I have a weblogic client application that is used to deploy/undeploy the application to weblogic server. The following code call undeploy() method to undeploy the application. But I still can see the application shown in the admin console after undeploying the app. Click the link of the app and the status is shown as "remove Successful".
// source codes
String protocol=”t3″;
String hostName=”localhost”;
String portString=”7001″;
String adminUser=”weblogic”;
String adminPassword=”weblogic”;
WebLogicDeploymentManager deployManager=SessionHelper.getRemoteDeploymentManager( protocol,hostName,portString,adminUser,adminPassword);
ProgressObject processStatus=deployManager.undeploy(new TargetModuleID[]{target}); //assume target is created already
However I can successfully undeploy the application in oc4j server by calling the undeploy() API. Is there anything wrong with my code?

Hi,
Sometimes back i developed a JMX code to Deploy and Undeploy the Applications may be that's going to be helpful for you :

Why won't my Razr Maxx ring when called from my home phone or the other cell phone (I-phone) on my Verizon account?

Why won't my Razr Maxx ring when called from my home phone or the other cell phone (I-phone) on my Verizon account?

Hi Ruth:
Thanks for reaching out to me about this issue.
This has been happening since I got the phone a couple of years ago.
I did not realize that my home land line and my wife's cell phone
always go straight to voice mail until my wife pointed it out to me
several months ago. Is there a setting I can adjust?
Yes, I can make calls to our home land line and to her cell phone
without being diverted to voice mail.
Any advice you might have would be most welcome.
Thanks.

Problem in Proxy call from an application deployed in J2EE engine

Hi,
I am trying Java Sender Proxy --> XI --> DB.
I have generated o/b proxies using integration builder.
<b>Following is the code that i am using for proxy call and it runs absolutely fine when runnning stand alone</b>
<code Controller.java>
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"com.sap.engine.services.jndi.InitialContextFactoryImpl");
p.put(Context.PROVIDER_URL, "server:50004");
p.put(Context.SECURITY_PRINCIPAL, "Administrator");
p.put(Context.SECURITY_CREDENTIALS, "password");
ctx = new InitialContext(p);
ref = ctx.lookup("sap.com/ProxySenderEAR/UsersSyncMI_PortTypeBean");
queryOutHome = (UsersSyncMI_PortTypeHome) PortableRemoteObject.narrow(ref, UsersSyncMI_PortTypeHome.class);
queryOutRemote = queryOutHome.create();
UserDT_Type reqtype = new UserDT_Type();
reqtype.setUsername(name);
reqtype.setPassword(pwd);
UsersDBMTResponse_Type response = queryOutRemote.usersSyncMI(reqtype);
role = response.getRole();
</code>
I am including this java file(Controller.java) in the same EJB project ProxyEJB which includes
my beans and home/local/remote interfaces.
Then I have created a Web Module Project ProxyWeb, that includes Proxy.jsp.
In proxy.jsp i am using the following code
<%
Controller obj = new Controller();
String name = request.getParameter("uname");
String password = request.getParameter("pwd");
String role = obj.getRole(name,password);
%>
Then I have included both ProxyWeb and ProxyEJB in ProxyEAR file, created Enterprise Archive and Deployed in J2EE engine.
and when I call the jsp...i am not getting expected result.
When i am debugging the code using try catch blocks for the controller.java...I observed that
Problem occured at :
<code>
queryOutHome = (UsersSyncMI_PortTypeHome) PortableRemoteObject.narrow(ref, UsersSyncMI_PortTypeHome.class);
queryOutRemote = queryOutHome.create();
</code>
what i am not able to uderstand is that ...when it is working fine when calling from standalone ...then
why it's giving me problems when deployed in j2ee engine...
note: I am using all required jars for XI.(included in ProxyEJB).And I have used NetWeaver Developer Studio for the above EAR,WAR projects.
Kindly suggest,
Regards
Vedavyas

The JNDI call is different when you call an EJB from inside the J2EE.
ctx = new InitialContext();
ref = ctx.lookup("java:comp/env/<JNDI-Name>");

Deployable Proxy Called From Portal

I've created and deployed a proxy on my portal application server. Then, from a portal service, I successfully look it up and invoke it. However, I'm getting a class loader error on the com.sap.engine.lib.xml.parser.tokenizer.XMLTokenWriter class.
I've added a sharing reference to my deployed J2EE component, and I know this is working because I can look up the proxy. What is strange is that this was working okay yesterday. It seems some class loading issue has come up since then.
Can anyone give me a pointer here?

To run a java program via a batch file,when called from a web server

REM This batch file runs the Spider with the [-v] option.
REM Lines 51 through 54 are simple DOS commands..they call the Spider
REM The location of the Spider package is the important piece of information here...
REM a batch file has access to the whole computer where the server resides.
setlocal
set JDK=C:\j2sdk1.4.1_01
set PATH=%JDK%\bin;.;%PATH%
CLASSPATH=%JDK%\jre\lib\*.jar;.;%JDK%\jre\lib\ext\*.jar;.;%CLASSPATH%
java spiderpackage.EntryPoint -v
endlocal
I am trying to run this batch file from my web server.I can see nothing on my browser.I can run the same program from my machine but unable to run from web server.what should I do?

I am making my question more clear...
I have a Windows batch (*.bat) file that echoes some html, then calls a java program the output of which is html as well, then echoes the final html.
To make sure that the java program gets properly executed, I set the necessary environment variables (e.g., JDK, PATH, CLASSPATH, etc.). The script looks something like this:
setlocal
set JDK=path_to_JDK
set PATH=path_to_java
set CLASSPATH=path_to_java_classes
echo ^<html^>^<body^>
call java foo
echo ^</body^>^</html^>
endlocal
The idea, of course, is to call this script through a browser, on a web server.
Curiously, both echo lines return to the browser just fine, but any output from
the java program (which just writes html to STDOUT) does not make it back.
Can someone explain to me why this is happening? How do I set things up so that the output (STDOUT and STDERROR) from the java program make it back to the browser?

Aysnch Proxy calling from Inbound Proxy

Hello Experts,
My scenario:-
Legacy sending File to Inbound proxy and from Inbound proxy I am calling the outbound proxy method to send the data back to Legacy system.
Its like File request -Inbound Proxy- Outbound Proxy Response- File.
FileRequest-Inbound Proxy----message in R3 as well in XI moni is successful.
File Outbound response-File-----message in R3 is coming as empty and because of this the message fails in Xi moni.
I tried to debug the scenario using test tab with the moni payload, I am able to see the data populated in debugging mode, But after the Outbound method is called the response message is coming is empty. commit work is also used inside outbound method.
I tried every possible ways,but not getting any clue.
chirag

Hi,
Just check...........in the inbound proxy code, the structure of the response msg is updated as the current structure of response msg.......may be you are filling the data in the old structure of response msg and then asssinging it in the outbound proxy call.......you need to fill the data in the new structure of response msg in your inbound proxy code.

How do I know if my application is running from within WebLogic server

I have an application that could be running either as a standalone
application (with its own VM) or as a servlet (within the WebLogic's
VM). How can the application determine the environment in which it is
running?

We have a similar situation here and we took the approach suggested below.
It does work, however it is creating one problem for us.
Sometime after the code below executes, our application attempts to
construct
the initial JNDI context (in order to look up an EJB Home). In the case
where
our application is running outside of a WLS instance, we get the following
exception:

... application code here ...
It would appear that the failed call to getT3Services() is leaving the
Weblogic client
runtime in a bad state (if we remove this call, there is no problem
constructing the
context).
So, the question I have is "is there any *safe* way to determine if an
application is
running within a WLS?". Thanks in advance for any additional suggestions.

Placing an alert call from MIDlet or server

Hi All:
I am working on a project where I need to alert the user of the MIDlet by placing a voice call automatically.
Say, user of MIDlet A sends files to user of MIDlet B through our server using http protocol.
As you very welll know, the IP address of a phone is not known to our server unless the MIDlet makes the http connection by itself.
Therefore, we need to worry about some way of alerting the user of MIDlet B about the file that is waiting for him at our server which he can pick by launching his MIDlet and opening http connection.
One possibility I am suspecting could have value is placing 'missed call' alert.
I am kind of stomped on this one and appreciate any pointers on how to solve this.
SMS is not an option.
regards,
Sambo

I am working on a project where I need to alert the
user of the MIDlet by placing a voice call
automatically.
Is making a voice call part of your project or just a possible way of solution you are thinking(by missed call)????
Say, user of MIDlet A sends files to user of MIDlet B
through our server using http protocol.
You can just set a flag on your server and design client midlet to check respective flag on regular interval n take the actions. This should be the best n easy solution to notify users. With these approach even large number of clients can be served quickly (within limited resources) as compared to (resources) making voice call(missed call).
Please let me know your views on this....
thanks & regards :)

Should I place a weblogic server outside my firewall?

I am looking at setting up an app server running an HR application. I want employees to be able to access it from home and internally at work. One option is to set up two app servers one internally and one externally outside the firewall. Another option someone suggested was to just set up some kind of external apache server that just redirects traffic to the internal app server through an open port in the firewall. I'm not sure what is best or what is most secure. I have a lot of reading to do. Can anyone advise on the pros and cons or suggest some good reading material? I will be using the most recent version of weblogic. Thanks.

You can set up reverse proxy and allow external users to access it via the reverse proxy.
Internal users will anyways have access to WLS.

Debugging Weblogic apps across the network

I am trying to debug a Weblogic app running on Sun from NetBeans running on Windows.
I am invoking Weblogic on Sun as follows:
java $JAVA_OPTIONS -classpath $CLASSPATH -Dweblogic.Domain=xyz -Dweblogic.Name=xyzServer
-Dbea.home=/export/home/nbhatia/sandbox -Djava.security.policy==/export/home/smitta/sandbox/wlserver6.0sp1/lib/weblogic.policy
-Dweblogic.management.password=$WLS_PW -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,address=8999,suspend=n
weblogic.Server
As soon as I put the -Xrun option shown above, Weblogic refuses to start. The
error I get is:
Transport dt_socket failed to initialize, rc = 509.
FATAL ERROR in native method: No transports initialized
Any ideas what I am doing wrong?
Thanks.

I have been able to connect with the following line:
"%JAVA_HOME%\bin\java" -hotspot -ms64m -mx64m -Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,server=y,address=8787 -classpath %CLASSPATH% -Dweblogic.Domain=mydomain

-Dweblogic.management.password=%WLS_PW% weblogic.Server
I had to move the -hotspot in front of the debug statements in order for the server
to start. Why that matters I don't know... but it started up (very slowly).
