I'm using ant on the command line, just as it comes out of the box, except that i've added ANT_HOME to my env. variablies.

My application server is jBoss, with JAVA_HOME and JBOSS_HOME added to env. variables as well.

Right, I've sorted out this issue, I had the path to the .class files wrong.

Still getting the javax.naming.NameNotFoundException: cs02gkStudentHomeRemote not bound problem though.

Any help is really really would appreciate!

I have just examined the contents of the jar file which is producded my doing "ant" and i've noticed that only the manifest, ejb-jar and jboss files are in there, and no beans.

Obviously this is the cause of the issue, but any idea how i solve it? Could it be something wrong with the descriptor?

I've just noticed that the exception is being thrown by this line:

Object ref = jndiContext.lookup("cs02gkStudentHomeRemote");

I have this in my ejb.jar-xml:
<?xml version="1.0"?> <ejb-jar xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee [url=http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd"]http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd"[/url] version="2.1"> <enterprise-beans> <entity> <ejb-name>cs02gkStudentEJB</ejb-name> <home>ca1.Task_41a41b.cs02gkStudent.cs02gkStudentHomeRemote</home> <remote>ca1.Task_41a41b.cs02gkStudent.cs02gkStudentRemote</remote> <ejb-class>ca1.Task_41a41b.cs02gkStudent.cs02gkStudentBean</ejb-class> <persistence-type>Container</persistence-type> <prim-key-class>java.lang.Integer</prim-key-class> <reentrant>False</reentrant> <cmp-version>2.x</cmp-version> <abstract-schema-name>Cabin</abstract-schema-name> <cmp-field><field-name>id</field-name></cmp-field> <cmp-field><field-name>name</field-name></cmp-field> <cmp-field><field-name>addressNo</field-name></cmp-field> <cmp-field><field-name>address1</field-name></cmp-field> <cmp-field><field-name>address2</field-name></cmp-field> <cmp-field><field-name>addressTown</field-name></cmp-field> <cmp-field><field-name>addressCounty</field-name></cmp-field> <cmp-field><field-name>addressPostcode</field-name></cmp-field> <cmp-field><field-name>dob</field-name></cmp-field> <cmp-field><field-name>course</field-name></cmp-field> <cmp-field><field-name>year</field-name></cmp-field> <primkey-field>id</primkey-field> <security-identity><use-caller-identity/></security-identity> </entity> </enterprise-beans> <assembly-descriptor> <security-role> <description> This role represents everyone who is allowed full access to the cs02gkStudent EJB. </description> <role-name>WholeDept</role-name> </security-role> <method-permission> <role-name>WholeDept</role-name> <method> <ejb-name>cs02gkStudentEJB</ejb-name> <method-name>*</method-name> </method> </method-permission> <container-transaction> <method> <ejb-name>cs02gkStudentEJB</ejb-name> <method-name>*</method-name> </method> <trans-attribute>Required</trans-attribute> </container-transaction> </assembly-descriptor> </ejb-jar>

Hi,

I'm a total newbie to EJB and i'm try to do some simple stuff. Add a student to a database, find him by primary key and remove him. I'm try to do the adding bit atm, but i'm getting a javax.naming.NameNotFoundException: cs02gkStudentHomeRemote not bound error.

I'm not really sure what this means or how to fix it, I'm willing to post any code that people want to see.

Thanks in advance

assuming that I know where ie is stored and the page that I want to load is stored how would I use System.exec?

Hi,

I have a program which i can compile and run using javac and java under windows, becuase i have set the CLASSPATH windows enviromental variable correctly.

I can't seem to do the same in netbeans.

Can someone please tell me either how to set the CLASSPATH for both compilation and execution in netbeans, or preferably for my ease how to get netbeans to use the system enviromental variables rather than its own?

Many thanks

Hi,

I've downloaded and installed these two packages:
NetBeans IDE + J2SE SDK
J2EE 1.4
from here

I'm trying to get into deveolping and using EJB (what i understand is part of J2EE) but whenever i have a file with import javax.ejb.*; I get an "package javax.ejb does not exist"

Have i missed a stage in the installation...such as adding J2EE to my enviromental variables?

Could someone please help?

Thanks in advance

Unfortunetly I have to go to work and I've not had time to test out your code, but dude, if that works...I'm gonna have to buy u an e-beer!!

I'll let u know how it goes!

Hi,

From a java program I need to submit information which is entered into a javascript form textarea and submitted via a submit command.

The webpage in question is: http://pgp.mit.edu/.

I have already managed to do the "Extract a key" thing using URL class in java but now I need to "Submit a key"

Does anyone have an idea how to do this? I guess the difference is that with "Extract a key" all of the info is encoded in the URL, with "Submit a key" it is not.

Oh, just one final note, obviously I can not change the javascript, but the java...i'll give it a sex change if it helps!

Any help would be greatly appreciated.

Thanks

Hi,

I'm cacheing a password for a variable amount of time (using a Date object.

I have two questions.

If I do

oldDate.setMinute(oldDate.getMinute + 15);
and the minutes are 46-59 does it automatically increment the hour and minus 60 from the minutes?

Also, how do I get the system to effectively know when the time is up?

Any help on this would be greatly appreciated!

I have a method which is passed a String.
I wanted to use that String as the name of a component ( a jLabel ) so that I can do, if the string is "hello",
hello.setText("whatever I want");
Is this possible? and if so how?
Cheers
