Hello Gurus:
I have a project that needs to use JMS in Spring with TIBCO is my JMS server. My question is when JMS is used in Spring framework, if a connection fails, does it Spring framework reconnect the connection automatically? Thanks much.

Hi,
A few years ago I used axis. I used netbean and tried to learn the new web services. Where should I start? I few overwhelmed with JAX-WS, axis 2, REST, web services with annotation, etc? Can some guru tell me which one the newest and easier to have a grip? I feel I need to start over. Thank you very much.

Dear Gurus,
I am new to WAS. In fact I use Websphere Integration Developer 6. I created EJBProject and stateless HelloEJB

I also created an Enterprise Application and Application Project which have references to EJB Project

I deployed ejb by adding Enterprise Applcation to the server. I saw ejb.ar and its jndi in admin console but I don't see any of those on ibm universal test.

Here is my code:

final String JNDI = "ejb/ejbs/HelloEJBHome";
Properties properties = new java.util.Properties();

properties.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.websphere.naming.WsnInitialContextFactory");
properties.put(javax.naming.Context.PROVIDER_URL, "iiop://localhost:2810/");
HelloEJBHome home = (HelloEJBHome)context.lookup(JNDI);

HelloEJB hello= home.create();
System.out.println(hello.greet("Blessing"));

I don't know whether I don't have the context properties right or I dont' have the jndi right. The jndi JNDI = "ejb/ejbs/HelloEJBHome" is exactly what is shown in the ibm-ebj-jar-bnd.xmi and in the admin console. Thank you very much.

John

My question was if I have a value of 192, how do I change this value of special A character. So the answer is

int value = 192;
String specialCharacter = "" + (char)value;
System.out.println("special A[" + specialCharacter.charAt(0) + "]");

Thanks to Paul and Pat for your kindness. It helps me a lot specially dealing with the hex.

If If have a numerical value of an int 192, its hex value is c0. How do I convert this numerical value into a special character?

For value of 256 or higher, when I cast that number to char, I just see [?]. I wonder that I have to set some sort of UTF8 but don't know how. Could you show me how to set the output stream? Thank you very much. You all have given a big help.

Hllo There,
I have to a need to convert a special character to a unicode but don't know how.

I see a unicode to a character but not the other way around. For example:

String original = new String("A" + "\u00ea" + "\u00f1"
+ "\u00fc" + "C");

becomes: A���C

but when I don't know how to convert � this to "\u00ea". Can someone show me please? Thanks.

I keep getting this error message. Please help


AXIS error

Sorry, something seems to have gone wrong... here are the details:

Hint: you may need to copy your class files/tree into the right location (which depends on the servlet system you are using).; nested exception is:

Hi,
I am using a vista OS. I cannot clean up the mess in axis folder. For some strange reson, I cannot delete the folder underneath. Let me rerun and post the message again.

BTW, my name is John McDonald, I also sent message to my friend, John Giang when tried to do two things at once.

Hi Gurus,
I compiled the java classes and copy them to tomcat\webapps\axis\WEB-IMF\classes. I deployed it with a wsdl file. But When I go to http://locahlhost/axis. I got the error message that I need to copy the class files. I examined carefully, the server side service, binding, and other classes if they are in axis web directory. They are. But why do I keep getting this type of error.

I can't undeploy them either nor can I force to remove the classes. Every time, it happy I have to copy the whole axis directory over. Please help and show the proper step. Thank you very much.

Could someone explain how to I use Configurable with the helloWorld class? How does that relate to <aop:spring-configured/>? Can someone just give me a real simple sample? Thank you very much.

John
Thanks and apologize for being a wrong forum. So I still puzzle of ThreadLocal. I googled a lot but don't find a good sample and well explanation. I have a java concurrency in practice but I don't see it much. Do you have any good source? And also does ThreadLocal have another alternative? Thanks again.

John
Thank you very much for a quick reply. Can you point out the different outcome when I just changed the way I input initial value to Client object? Thanks much.

John
Hi Gurus,
I start learning ThreadLocal. I have basic knowledge that is a separate thread to hold a separate value but I don't know if there its practical usage. Could you explain it? Is ThreadLocal useful?

I have the following code

The output is:
New local thread + Thread-0
New local thread + Thread-1
Thread Thread-1 has client Client[2]
Thread Thread-0 has client Client[1]


But if I change the initialValue method to be:

Then output is:
New local thread + Thread-0
New local thread + Thread-1
Thread Thread-1 has client Client[1]
Thread Thread-0 has client Client[1]


Could someone show me why? Much appreciated.

I used the 1.6.3 sdk. I don't remember somehow I got away with it. And now it come back. Thanks.

John
I was working on my project and it was fine until I did refresh loading into eclipse. Does any one has any clue? Thanks.
