Using Document/Literal style in Axis (WRAPPED style) how do i handle complex java data types.Can any one send me an useful url where i 'ld
get ample example.My concern is I have Complex java Classes to be
handled in web services where my services will be invoked by diff client

(.Net/other).

I need Interoperability.

Kindly send me URL where i can get Examples/Samples/Tutorial.

Hi
Could any one tell me how through JCA or Adapter an app server gets connected to Legacy System and query in standardize wzy through sql.
HOW THE COMMUNICATION HAPPENS MEANS
STANDARDIZE QUERY LIKE SQL SYNTAX COULD BE FIRED FROM EJB/CORBA B.O
TO ADAPTER TO GET AND PUT DATA THROUGH LEGACY SYSTEM COZ THEIR QUERY
MIGHT BE DIFFERENT THAN SQL QUERY COZ LEGACY SYSTEMS WOULD HAVE THEIR
OWN QUERY.
NOW HOW ANY API / ADAPTER CLASSES CONVERTS OR MAPS THE REQD LEGACY SYSTEMS
QUERY TO STANDARDIZE QUERY OR ANY MAPPING OR DOES THE API EXPOSES
ANY STANDARDIZED SQL QUERY TO LEGACY QUERY.THERE IS A CONCEPT OF
GATEWAY PROVIDED BY APP-VENDORS TOO.

COULD ANYONE HELP OUT TO CLEAR THE CONCEPTION IN JCA/ADAPTER/GATEWAY
SCENARIO AND GIVE LINK HOW QUERY WOULD LOOK LIKE & HOW TO
DO THIS WITH ANY APP SERVER LIKE WEBLOGIC 8.1.THE TRANSACTION
IS ON 2PHASE AND DISTRIBUTED TO DIFF LEGACY SYSTEMS.HOW TO GET
THE STANDARDIZED SQL QUERY AND INTERNAL MECAHANISM OF CONVERSION.
GOOD LINK FOR CONCEPTION CLARIFICATION + EXAMPLES TO UNDERSTAND THE
EXECUTION.PREFERABLY WITH WEBLOGIC 8.1.
THANX AND REGARDS

could any one tell me is it possible to have same ejb name in different module in same or different application in one server (container(1 jvm)) with
different JNDI name?If so how is it possible to bind in jndi and how the
JVM or classloader behaves and distinguishes the diferences & loads up
the proper one.?
And how is it possible in diff jvm or container groups (server groups)
cloning or in horizontal scaling in clustering mode (distributed).
Could nay one tell me how JVM 's behaviour or classloaders when we deploy
/make an application (.ear) a module level / server level. How does it
vary in terms of jvm and its charactersistics.
Websphere 5.0
could anyone tell me how Singleton pattern could be implemented in Clustered
Env S1->S2-S3 like.And how do i get to know w/c server its belongs to and
how to manage in Clustered Distributed env & model it.Pls elaborate it or give URL.
Could any one tell me how horizontal scaling works?
Suppose i have S1-->S2--->s3--->S4--->s5-->DBServer
Now if a client is on transaction and the session is active on the first
server .Now suudenly the S1 fails how does the session gets saved / propagated to S2 to take over or what is the way to handle this kind of failover w/c client won't get affteceted but the transaction would go safely
with session data.
Pls explain the config in perspective of Weblogic & Websphere & the concept.

hi
I am facing performance issue in HttpTunneling .Needs help.
I am using java.net.URLConnection(); and Object
outputstram and object inputsteam for getting data
from servlet.But after some hit.In Lotus server
its getting slower and ultimately getting thread block for servlet.
Problem Facing
In tomcat,Resin,Weblogic there was no problem.But
in Lotus server.After few hits its saying the thread is blocked.
And i am also thinking that URLConnection does not have anything called
connection.close();
So when hit increases.What kind of optimization could be done to get the
best speed.
1) Should i go for SingleThreadModel interaface???
2) Should in put synchronised block with this object around the dataaccess and tree generation part??
3) But what about creating too many socket connection ?I mean
opening the URLConnection??How do i get the best optimized one.
So that none of the server complains me.??If you have any kind of
sol/idea pls let me know.
if any better optimisation can be possible or any other way
so that it works in best way.Since applet has to be downloaded very
fast and its carrying bit larg jar and doing operations.
Time being I ahave hardcoded the url for servlet .I can use the getcodebase() then the servlet path.But what about the connection and performance related sol.
How to optimise in several connection
related and stream related issues.

hi
I have successfully deployed a hyperbolic tree
thro' httpTunneling.The only problem i am facing.Once the applet calls the servlet from the jar file its opening a URLConnection.and doing the rest of the operation.After accessing 20-30
times its giving some kind of thread is blocked
/servlet/NetSkillDAServlet means already in use.
How do i get out of it.None of the server like
tomcat,resin,weblogic behaves like this.Is it something with the code or some config has to be done.If anyone could advice me what to do.

Applet code:

webServerStr = null;
hostName = "....."
port = "8080";
servletPath="/sevlet/NetSkillDAServlet";
webServerStr = "http://" + hostName + ":" + port + servletPath;
URLL url = new URL(webServerStr);
URLConnection urlconnection = url.openConnection();
ObjectInputStream inputFromServlet = new ObjectInputStream(urlconnection.getInputStream());
Vector dataFromServlet = (Vector)inputFromServlet.readObject();

Anything else to do?? Coz URL connection does not
have something to close.But its not giving error in any other servers.
thanx and regards

Hi
I am facing the problem in applet servlet communication in lotus Domino server.Client classes is properly identified but not the servlet (server class) and its dependencies
The jar file i am putting in servlet dir.
and setting in env.and calling
http://m/cname:80/servlet/DAServlet
But its unable to locate from jar.
And gave an error Java.util.List not found.
In documntation it says it suppports only
upto jdk1.1 and rt.jar stuff the server takes
from inside jre.So even i pass jdk1.2 onwarsd
class the servlet classloader won't recognise.
The servlet is not getting initialized ot not
comming.So applet giving unknown resource
If anyone worked on lotus server pls try
to help me
thanx and regards
