Problems with the tutorial Introduction to Java Servlet technology

Has anyone done this tutorial?
https://www6.software.ibm.com/developerworks/education/j-intserv/
I created an application. Created the XML file. Imported the project from the website and tried viewing it in the broswer:
http://localhost:8080/contacts/
I get this:
HTTP Status 404 - /contacts/
type Status report
message /contacts/
description The requested resource (/contacts/) is not available.
Apache Tomcat/5.0.28

that means you didn't deploy the app properly.
go read the tomcat docs for "your first web app"

Sqljdbc4 driver problem with the latest version of java (java6 update9)

Hi all, sorry for my ingles.Need help with a problem, I have to connect to sql server 2008 from Java, I had install the Java SE Development Kit 6u22, and when the upgrade to the 6u29, the driver stopped working, they let the following example:
public static Connection getConnection(String db_connect_string,String jdbcDriver)
Connection conn = null;
try {
Class.forName(jdbcDriver);
conn = DriverManager.getConnection(db_connect_string); //when you run this line, does nothing mores, nor throws errors
} catch (Exception e) {
System.out.println("Error de conexion." + e.getMessage());
return conn;
uninstall update29, and install that before and had returned to work. Still do not know how to solve this problem with the latest version of java. Any ideas?.
Thanks.

You are not the only one.
MS SQL JDBC does not work with 1.6.0_29?

Problems with the Tutorial...

Hi,
I've installed kodo 2.5.2 in Websphere ver.5.
I've followed all the instructions to run the tutorial:
I put all the *.java, .jdo and .properties files in a new Project named
JDO_TEST.
After using the menu "Add enhancer to build" with the file "Animal.java",
I've rebuilded all the files and then in the kodo's window appear a
message error.
I've opened the log and this is what i've found:

Pluso,
It sounds like your project files are not in the classpath that Kodo
is seeing. Is this at all possible? Can you ensure that your project
classpaths are correctly set up?

Problems with the ActiveX bridge for Java beans when using third-party .jar

I encountered the following problem when using the ActiveX bridge for a java bean:
I am using JDK 1.4.2_09 and MS Visual Basic 6.0 (SP6). I wrote a java bean called ProcessViewer (my class ProcessViewer inherits from JComponent and implements the interfaces Serializable and AdjustmentListener) which I would like to use within a VB 6.0 application. I used the ActiveX bridge (packager.exe) to generate a DLL (ProcessViewer.dll) and registered it successfully. The java bean GUI-control works fine within my VB 6.0 application unless my java bean (ProcessViewer.jar) uses any third-party .jar files.
But when I tried to add a reference to some third-party class (com.sap.xxx.xxx....) I got some problems. I could solve the problem with packager.exe by setting the correct CLASSPATH. But at runtime my VB 6.0 application does not work. It crashes or it reports an error like this: "The control ... could not be loaded from axbridge.dll" (although I deployed my .jar file correctly to the directory C:\Programme\Java\j2re1.4.2_09\axbridge\bin and lib). Setting the CLASSPATH environment variable before calling my VB 6.0 application (exe) did not solve the problem.
How can I teach my VB 6.0 application (containing the Java bean ActiveX control) where to find the third-party .jar file? Copying the third-party .jar file to the JRE lib-folder or to the axbridge\lib folder did not solve the problem either.
I studied the documentation about the ActiveX bridge given at:
http://java.sun.com/j2se/1.4.2/docs/guide/beans/axbridge/developerguide/index.html
but I am missing informations on how the third-party .jar files can be found during runtime of the ActiveX container (e. g. a VB 6.0 application).

Compilation Problems with the Tutorial in JDeveloper

Hello!
I'm a new user of JDeveloper. So this is typical newbie problem! I am planning to develop a Web Application using JDeveloper 3.0(JRE 1.1.8) and Oracle 8i (8.1.1). As a start I installed JDeveloper and on an Oracle Client machine and tried to run through the tutorial. The tutorial on "Builing Business Components" (displays master-detail relnship between dept and emp tables in the scott/tiger schema) worked fine. Then I tried to convert this to a WebApp - the jsps were generated alright. However when I tried to run main.jsp ..I got a host of errors of the type :
Error (0) : /Program Files/Oracle/JDeveloper 3.0/myprojects/ not contained in /Program Files/Oracle/JDeveloper 3.0/myprojects/WebApp2/contents.jsp.
This problem repeated for all the jsp files.
Clearly some environment variable needs setting. HELP!
Regards
Mona

Problems with the Tutorial in the MDK Documentation

Hey,
I have made the tutorial-exercise of the MDK-documentation, in which You try to create a SyncBO and let generate the client application.
When I do all the steps and import the generated XML-file into my Eclipseproject, it should be possible to test the application on the client, after uploading to the middleware.
But when I download it to the client by synchronizing and when I´m clicking on the shown link then, it doesn´t start!
I get the message "The page cannot be found..".
But when I´m installing other application, like f.e. MAM, I can start it....
Any ideas?
Many thanks!

SSL and J2EE - Problems with the tutorial

I'm trying to make a small amendment to the bank application ('Duke's Bank') which is the main example in the J2EE tutorial. Nothing complicated: just add a simple 'enrollment' page which will be secured through SSL.
The aim is to demonstrate that J2EE makes it very easy to put a session over a secure SSL channel.
As I read the documentation, this should be a fairly simple thing to configure. Add a 'CONFIDENTIAL' network security requirement to the WAR component through the deploytool and import a server certificate using keytool. I've done all that and the thing won't work.
After adding the 'CONFIDENTIAL' requirement I find that using the 'http' protocol serves up a server certificate which I can choose to trust through by IE6.0 browser. But then the application freezes. If I use the 'https' protocol the application freezes without even bothering about the certificate.
I wonder if the J2EE tutorial setup is so tightly packaged that configuring it for SSL involves a number of undocumented steps related to ports, keystores and security providers. Explaining it all within the context of the tutorial would throw it out of scope so we're not really meant to do things like adding SSL.
This is a big deal for us -- we're trying to decide if J2EE will be our application platform over the next five years or so. Any assistance here will be gratefully received.

The Duke's Bank tutorial can be found at:
http://java.sun.com/j2ee/tutorial/1_3-fcs/
It is the last chapter of the tutorial, under the "Putting it All Together" section.

Problems with the resources boundles in java studio creator 2

I try to migrate a proyect from sun java studio creator 2 early access to sun java studio creator 2 but I have a problem, the resource bundle work in creator 2 early access but doesn� work in creator 2, somebody have the same problem?
and, the most important somebody could fix the problem?
Note. sorry I�m learning english

If I choose for SJSC2 to create JSF applications then
one, or better THE, reason is the (drag and drop)
Design editor functionality.
Using resource bundles is a MUST. So if this means I
cannot use the Design Editor in combination with
resource bundles, then I will use something else...
I think there should be a statement issued by the
SJSC2 team about this bug and what the timescale for
a decent solution wll be.
Regards,
Marcel
BTW: overall SJSC2 seems to be a good alternative to
develop an open source JSF application in a competing
timeframe.I agree. This bug is even more exacerbated by the fact that the error message is entered in the design form and generally clutters more room than was originally intented for the text. Not having i18n is a show stopper right now. Creator2 will have to fully support i18n before we can start using it.

Hi Denis,
This looks like a memory issue, similar problems have been posted on this forum before.
Change the following params.

Has anyone else had problems with the latest system updates to Mac OS X v10.6.8 with the java virus patch?

After installing the latest updates to Snow Leopard the system hangs up and will not open properly. This is the update to Java, etc after the virus was discovered. I have done the updates on four different systems with the same result.

No problems with the Java update here, although I have Java disabled. Might try reapplying the Java standalone while in Safe Boot (Shift at startup chime), if you did it from Software Update.

Error thread java : problem with the function "resume 0x***" (forum sun)

One problem with the function of jdb occured when I tried to use it to
pilot the processor with differents threads. In fact, I use a simple example with 2 threads.
I stop the two threads with two breakpoint, and I want to resume one or the other (with the function "resume 0x****"), the one wich I resumed stop again on the breackpoint and I decide again to resume one or the other. All of that to obtain a tree of execution.
I give you the code of the class and the code of jdb.
CLASS: (it's just a object Room with a variable degre that I increment and decrement with two threads increase and decrease)
public class Test{
     public static void main(String[] args){
          Room r = new Room();
          decrease de = new decrease(r);
          increase in = new increase(r);
          de.start();
          in.start();
class Room {

PS: I tried many other examples with other class and other kind of breakpoints, but, in any cases, on thread doesn't manage to resume. When I try with general resume (no specification of the thread), It works but it isn't interresting for me because I want to decide wich thread continue his execution.

Solution Manager systems RAM requirements - problems with the Java Engine

Hello,
I am about to install SAP Solution Manager 7 on a WIndows 2003 Server x64 but I need to know what the RAM requirements are? I have been having problems with the Java Engine starting and it seems to time out, I have heard that this is a very RAM hungry process and it might be why?
Many thanks for your help in advance,
Omar

Hello Omar,
To size SAP Solution Manager 7.0 EHP1 we recommend to use the SAP Solution Manager Quicksizer Tool at:
http://service.sap.com/sizing-solman
Here you find information on how to use the tool, how to collect input data for E2E Scenario Sizing, on SAP E2E RCA Sizing, Introscope Tuning, Wily Enterprise Manager Cluster Setup for E2E RCA Scenario and BI Aggregation Strategy in E2E Scenario.

Problems with the jax-rpc testcase from the JWSDP tutorial

Hello.
I have e few problems with the hello case from the JWSDP tutorial.
Everything works fine during the build/compile/installation phase but when I'm accessing the url http://localhost:8080/jaxrpc-hello/jaxrpc, the server wont find the service and I get:
404 The requested resource (/jaxrpc-hello/jaxrpc) is not available.
I've trippel checked the environment settings and other properties and I don't know where to go to error check.
I've tried to install the client as well but it wont detect the service so I guess there is a problem on the server side.
I'm quite new to the whole "Web Service thing" So I would be happy to get som help.
Chris

if you run the tomcat manager application at http://localhost:8080/manager/list, what do you see? I suppose if you have successfully run the ant "install" task after "compile-server" and "xrpcc-server", you will see that your service is registered with its context path, but is not "running". This will be probably because of a runtime error. For further diagnosis of errors like these, I recommend to take a look at the log file at "<%JWSDP_HOME%>/logs/catalina.out".
If you are satisfied with this answer, please be so kind and assign some of your duke dollars to me ;-)
