Thread: where can i find the tmp/foo directory?

hi all,

please, i would like to know where i can find the tmp/foo directory so i can edit the jndi.properties

thanks for your response

The tmp/foo directory for what application, is this some directory used by an application container?

// Json

Hi Json,

thanks for getting back to me.

actually, i am developing a three tier application using J2ee 5. i defined my business methods in the session beans with which i used to create my web services in the ejb and web service clients in the war tier.

however, i sometimes have this error: "NameAlreadyBoundException, use rebind to override"; and then i have to keep undeploying till the server gets rid of it. otherwise, my code works perfectly well.

now the error has come again and i read online, that i need to edit thejndi.properties file in the /tmp/foo directory and i dont know where to fine ths directory.


secondly, i sometimes have this warning that appears in the war tier when i build it for it to parse the wsdl and generate the necessary code for the application.
the warning is below

"[WARNING] schema_reference.4: Failed to read schema document 'http://localhost:16047/AlternateWSService/AlternateWS?xsd=1', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.
line 28 of file:/C:/Users/owner/Documents/NetBeansProjects/msc_project/msc_project-war/src/conf/xml-resources/web-service-references/AlternateWS/wsdl/localhost_16047/AlternateWSService/AlternateWS.wsdl#types?schema1"

please note that whenever these two errors dont appear my application works perfectly.

i hope i have explained all. i will appreciate if you could help.

thanks.

What container are you running your application in? Glassfish, Weblogic, Jboss or maybe something else?

// Json

Json,

just a quick one.
i was carried with with the details of my application.
i am using Glassfishv3

in <glassfish installation folder>/lib there is a file called appserv-rt.jar, in that file there is a jndi.properties file and if you are using a custom one it would be located in your <glassfish folder>/domains/<domain name>/lib folder I believe.

What do you need to change in that file?

// Json

i got this lead from google that i should set a jndi name for each of the remote server beans i have got to solve the first problem.

please if you have better ideas i would appreciate

What code do you use to bind your ejb names to the context?

// Json

i do not get this question.

but for all i know i do not have any code binding the ejb names

pls through more light as i am new to J2ee

Because of the NameAlreadyBoundException that you get you could try using the rebind method like they state in the message.

// Json

Json,

below is what i have using netbeans

i have a class called Locations in the ejb

and the i defined the methods and operation of the calss in a LocationServer that implements it remotely in a class called the LocationServerRemote

after which i created LocationWS class from the LocationServerBean

public List<Locations> getLocations() {
return ejbRef.getLocations();
}

}

and that was it with the ejb.
n/b there are other classes but i am showing you what i have done with one of the classes.

in the web archive, i then created the web service clients from the web services to generate required classes and codes and create the LocationWSService/Ports

then in the war, i created a LocationBeanthat the web pages call to generate result as required by a user.

that all i can explain for now, i would like more clarifications pls
thanks

there was no method specified for me to use
