JBuilder 8 and J2EE, what adjustments do I make?

I have JBuilder 8 SE and I am trying to dabble in Servlets and eventually EJB. I was told that I need to add the location of the servlet.jar to my CLASSPATH environment variable to allow JBuilder to compile Servlets, is this correct and do I have to do anything else with evironmental variables to achieve full IDE functionality with J2EE?
thanks,
Rob

it depends on what you mean by "full functionality"...
Instead of using servlet.jar, use the j2ee.jar. This will allow you to compile any classes that make use of J2EE classes (ejb, servlet, jms, jca, etc.)
However, your ejb/servlets will not run as they need a container to run in. Generally this container is implemented by an app-server. To actually deploy your code and have it work you'll need to use an app-server.
A few app-servers are:
Weblogic (www.bea.com)
Websphere (www.ibm.com)
JBoss (www.jboss.org)
Tomcat (go to the j2ee tutorials on this site)
You'll have to download, install, and configure an app-server. Then you'll have to deploy your code in the app-server (the steps vary significantly by app-server). Finally you'll be able to run your code.

My iPhone 4s's wifi button is no longer touchable prohibiting me from connecting to wi-fi. How do I resolve this? What adjustments should I make?

Hi!
My iPhone 4S's wi-fi icon is greyed out, which means I can no longer connect to wi-fi. How do I resolve this?

Greyed out means your WIFI chip has bit the big one.
You can either have it repaired at a local shop.
Pay Apple to exchange it out of warranty (should they see fit to do so).
Order a new chip off ebay and do the work yourself.
Sell your iPhone and get a new one.
Or just go without WIFI.

JWSDP and J2EE Integration: Doesn't work. What's the point?

My problems involve the integration of JWSDP and J2EE as described in these two documents:
http://developer.java.sun.com/developer/technicalArticles/WebServices/wsj2ee/
http://java.sun.com/j2ee/documentation/windows_guide.html
It looks like a long one, but it�s really not that bad. All comments are appreciated.
I�ve numbered each line-paragraph-section for easy reference later.
(1) My ultimate goal is to setup a website that displays data from a database. I will use Java, Apache, Oracle, and whatever else I need to create a website that uses servlets, JavaServer Pages (JSP), and JDBC.
(2) I�ve got four Pentium III computers:
1. Windows 2000 Server to be the web server (MyWebServer, IP = 10.10.1.1).
2. Windows 2000 Professional to be the database server (MyDatabaseServer, IP = 10.10.1.2).
3. Windows 2000 Professional that I use to develop and test (MyDeveloperPC, IP = 10.10.1.3).
4. Windows 2000 Professional that I use as a client to connect to the website (MyClientPC, IP = 10.10.1.4).
(3) On MyWebServer I installed the following:
Java 2 Standard Edition (J2SE)
Java 2 Enterprise Edition (J2EE)
Java Web Services Developer Pack (JWSDP)
The JWSDP tutorial
Apache HTTP Server
(4) The files I downloaded and installed are as follows:
j2sdk-1_4_0-rc-win.exe
j2sdkee-1_3_1-win.exe
jwsdp-1_0-ea1-win.exe
jwsdp-1_0-ea1_01-tutorial.zip
apache_1.3.23-win32-x86-no_src.exe
(5) After installing these products, I set the environment variables as follows:
JAVA_HOME = c:\j2se
J2EE_HOME = c:\j2ee
JWSDP_HOME = c:\jwsdp
Path = c:\j2se\bin;c:\j2ee\bin;c:\jwsdp\bin; [and other previous statements]
(6) I checked to see that Apache is running as a service. It is.
On MyWebServer I start Tomcat and J2EE. Both start properly and are operating simultaneously.
(7) From MyClientPC I open Internet Explorer and in the address box I type:
http://10.10.1.1
This displays the page c:\ApacheHTTP\apache\htdocs\index.html.en (The Apache default server installation page.)
(8) I then enter this address in IE:
http://10.10.1.1:8080
This displays the page c:\jwsdp\webapps\root\index.html (The default JWSDP page).
(9) I then enter this address in IE:
http://10.10.1.1:8000
This displays the page c:\j2ee\public_html\index.html (The J2EE 1.3 Default Home Page).
(10) So far so good. Now I want to test JWSDP as a container for JSP pages.
(11) I use ant to build the converter app found in the tutorial examples (in folder c:\jwsdp\�\tutorial\examples\gs). I then deploy the converter app to the c:\jwsdp\webapps\gs folder.
(12) From MyClientPC I open Internet Explorer and in the address box I type:
http://10.10.1.1:8080/gs
The converter app works perfectly.
(13) To eliminate the need to enter the port number, I create a link from the Apache default server installation page to the converter app. From MyClientPC and enter this address into IE:
http://10.10.1.1
I then click on the link to the converter app and it works perfectly.
(14) Question: Is this the best way to display JSP pages without having to enter the port number?
(15) Now it�s time to integrate JWSDP and J2EE as described in these two documents:
http://developer.java.sun.com/developer/technicalArticles/WebServices/wsj2ee/
http://java.sun.com/j2ee/documentation/windows_guide.html
(16) After I complete this integration I cannot start both Tomcat and J2EE at the same time. This makes sense because they both share port 8080.
I start Tomcat.
(17) From MyClientPC and use Internet Explorer to test the various relevant addresses. Everything works the same as it did before except this one:
http://10.10.1.1:8000
The page cannot be displayed. The J2EE default home page is not displayed, which makes sense because the J2EE port is no longer 8000; it has been changed to 8080.
(18) Now I shutdown Tomcat and start J2EE.
From MyClientPC and use Internet Explorer to test the various relevant addresses:
(19) http://10.10.1.1:8080
Displays the JWSDP default home page.
(20) http://10.10.1.1:8080/gs
The page cannot be displayed. The converter app no longer works.
(21) From MyWebServer and use Internet Explorer to test localhost:
http://localhost:8080
This displays the J2EE default home page.
(22) Question: Why does localhost give me a different page than the IP address?
(23) Question: What was the point of integrating JWSDP and J2EE?
(24) I want to get the converter app working, so I create a .war file and attempt to add it to the J2EE deploytool (see the two integration documents listed above at section 15.) I create the .war file following the instructions in the JWSDP tutorial:
http://java.sun.com/webservices/docs/ea1/tutorial/doc/WebApp3.html#64606
(25) I change to the c:\jwsdp\�\tutorial\examples\gs\build folder.
I then type:
jar cvf converter.war .
A .war file is created.
(26) I open the deploytool: File, New, Application, and I name it �converter�.
I attempt to add the .war file: File, Add to Application, Web WAR.
(27) When I attempt to add the converter.war file I get this error:
�converter.war does not appear to be a valid web JAR.�
I tried a few different attempts, all with the same result. I�m stuck.
(28) I ask again, What was the point of integrating JWSDP and J2EE?
(29) If this is the preferred configuration, how do I display my JSP pages like the converter app?
Please help!!!

The JWSDP tutorial says to be in the �build� folder of the example when issuing the jar command to create the .war file. The build folder is created when I run the �ant build� command.
Attempt 1 from the command prompt in folder c:\jwsdp\tutorial\examples\gs\build>
I typed this command:
jar cvf c:\jaxmservices\converter.war .
In this case I directed the .war file to be placed in a different folder as you suggested. Here�s the output:
added manifest
adding: index.jsp(in = 921) (out= 525)(deflated 42%)
adding: WEB-INF/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/classes/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/classes/Converter.class(in = 582) (out= 358)(deflated 38%)
Didn�t work. Same error as before.
Attempt 2 from the same folder:
I typed this command as you suggested (I tried it with and without the final dot):
jar tvf converter.war
Here is the output:
java.io.FileNotFoundException: converter.war (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:103)
at java.io.FileInputStream.<init>(FileInputStream.java:66)
at sun.tools.jar.Main.run(Main.java:185)
at sun.tools.jar.Main.main(Main.java:904)
I tried a few other variations on these attempts with no luck. I�m stuck.
I�m attempting to create a .war file out of two files: index.jsp and converter.class.
Now that I�ve integrated JWSDP and J2EE, is there some other way that I can run the converter app instead of a .war file and the deploytool? In other words, if I go back to using ant to build and deploy converter, where would I deploy it so that it will work with J2EE?
By the way, it doesn�t have to be converter. I�d be happy if I could get any JSP page to work in J2EE after the integration.
Forever grateful,
Logan

Do u know what is jdk 1.4.1 and j2ee 1.4.1?

hi~ do u know what is jdk 1.4.1 and j2ee 1.4.1? Are they sotware program like jbuilderX for example? Do u know which of these 2 is better for jxta? Do u know the installation procedures for jdk1.4.1 and j2ee1.4.1? thanks!

jdk means J2SE(Java Software Development Kit)
is it j2ee or jre?
No they are the main software for run a java program.
jbuilderX is a editor where you can write java programs using jdk or jre.
Both are need for jxta.
Just run jdk 1.4.1 setup.exe file.That automatically install jdk and jre to your PC.

What is their difference betwwen Sun ONE Application Server and J2EE serv

Sun ONE Application Server is Sun implementation of J2EE server.
But it seems even no Sun ONE Application Server, use J2EE SDK command
j2ee -verbose
we still can launch an Application Server that support EJB, JSP....
what is their difference betwwen Sun ONE Application Server and J2EE server provided by J2EE SDK ?
Thanks,

Sun ONE generally refers to the Sun ONE Application Server version 7.x. This is a J2EE 1.3 compliant application server from Sun. Sun also released a Reference Implementation version (RI) as a requirement of the J2ee 1.3 spec. This is the J2EE server you are refering too. The Sun ONE Application Server 7 is a more robust production ready App Server.
Going forward, Sun combined the 2 seperate groups to include just 1 release. The J2EE 1.4 Reference Implementation is the Sun Java System Application Server Platform Edition version 8. SJS AS 8 PE is both free and production ready. Other version will include High Availability, Managing and Monitoring features.

J2SE and J2EE Which with what ?

I am running Windows NT 4.0 server, with SP6a & Windows NT 4.0 work station, with SP6a. On reading the various combinations of J2Se and J2EE, which do I need to match. Also I am using ant 1.5.3 and looking at some CORBA 3 work using JacORB 1.4.1. I have been using J2SDK 1.4.1_02 for general jave work.
From what I have been reading it looks as if I need J2SE 1.3.1_02 with J2EE 1.3.1.
What is the real combinations of J2SE and J2EE needed for such a asystem ?
Also at present I do not particularly wish to move to a Win2000 Server/workstation combintion as yet.
Thanks
Omegaall

You may now download J2EE 1.4 which will be compatible with your existing installation of J2SE 1.4.1_02.
However, J2EE consists of the application server and additional tools. They are not required, nor are they recommended for heavy duty enterprise work; J2EE is simply a basic "reference" platform for you to get your feet wet on.
Other alternatives do exist, and if you've tracked down Ant, you probably already know about Tomcat, JBoss, WebSphere and a number of commercial engines. All of these packages essentially take J2EE and extend them further (or are faster, or are more reliable, etc etc).
If you have been asked to develop COBRA objects - as opposed to, and I stress this, as opposed to - merely being interested in the technology, then I strongly strongly strongly suggest you find out what your customer is using and set up a scheme similar to theirs. By developing to the same platform, you can save yourself a lot of deployment and packaging headaches, and essentially develop the objects "the right way" for that system.

What is the difference between JDK and J2ee

Could someone explain, in simple terms, what is the difference between JDK and J2ee. I am trying to understand the difference.
THanks

Could someone explain, in simple terms, what is the

A JDK is a set of tools for Java development including compiler, runtime system and standard libraries. J2EE is the enterprise version of the Java technology platform (it's one of three). To use it you download the proper JDK's.

JBuilder 3 and Weblogic 4.5.1 - urgent!!!

Rajni,
I occasionally have that problem with JB3. A solution is to clear out your
compiled classes directory. For most projects , this is "myclasses".
Hope this helps,

You have to remove weblogicaux.jar from the Java Libraries in project

we used to have that problem. Just use only c:\weblogic\classes, that'sall
it needs to get your program compiled.

Difference between J2SE and J2EE...

Hi all. I was wondering what the difference between J2SE and J2EE were. I mean in the code structure. Are the packages the same, like Swing, IO, things like that. I'm a bit of a beginner in Java, only been messing around with it for about 6 months now kind of in my spare time, and I know I'm in now way ready for J2EE, but it's something I think I'd like to maybe look into. I know it's for Enterprise Applications, much bigger scale than I'm used to, but fundamentally, how is it different? Different coding conventions? New packages not in J2SE? I hope what I want is coming across okay. Thanks for all the input.
James

J2EE defines a large number of specifications, in addition to J2SE. Examples are the Servlet, JSP, JMS, and EJB specifications. Most of those specifications are designed to have implementations running inside an Application Server. There are free implementations available such as JBoss (combined with for example Tomcat), and I think youre best bet to learn is to download one of those and go from there. Servlets and JSP are a good beginning, and then maybe move on to EJB and the rest.

ABAP and J2EE-Stacks in SAP WEB AS

Hi,
I have two questions about the technical architecture of SAP WebAS, particularly about the ABAP- and J2EE-Server.
Can someone recommend detailed papers/guides (besides help.sap.com)describing:
1) the management of processes and resources in two parts (ABAP and Java)
and
2) The communication mechanisms between J2EE- and ABAP-server.
What are the problems with JCo?
Is there other possibilities to communicate between 2EE- and ABAP-server.(besides JCO), what is the performance in this case compares with JCO?
Thank you!

BPM standalone and J2EE versions

What is the diffrence between BPM standalone and J2EE versions
and
What are the advantages of Using J2EE Version over standlone?
In configuration document it is mentioned that we need to deploy wlj2eedeployer.ear on weblogic server.
Why this deployment?
Thanks

Depending on your needs, the Engine can be deployed using two different implementation styles.
Standalone Oracle BPM Enterprise Engine
Oracle BPM can be deployed in a standalone environment running on a JVM. This is the original version of the Engine and has been around for 10 years.
The benefits of deploying processes to Enterprise Standalone are:
<li> It does not require an application server J2EE container to run. This means a lower cost of entry if you do not already own WebLogic or WebSphere J2EE application servers.
<li> It is simple to install and administer.
Enterprise Standalone uses a simple active/standby failover mechanism. When the active engine starts, it immediately registers in the Oracle BPM Directory that it is the primary engine. When the standby engine starts on another machine, it sees that another engine has already registered as the active server in the Oracle BPM Directory. Since the active engine is already up, the standby knows that it needs to ping the primary engine periodically to ensure it is still up. If the standby engine fails to get a response from the active engine, the standby notifies the Directory that it is now the active engine. When what was previously the active primary engine restarts, it notifies the Directory that it has restarted, sees that another server is now the primary and then starts as the secondary.
J2EE Application Server Oracle BPM Enterprise Engine
Oracle BPM Enterprise engines can also run on a J2EE application server within WebLogic and WebSphere containers.
Oracle BPM Engines running on a J2EE Application Server support active clustering. This means that as loads increase over time, new nodes can be added making the environment more scalable over time.
With the J2EE Application Server environment automatic failover is automatically provided across nodes.
Finally, in answer to your last question - the deployed wlj2eedeployer.ear is useful because this lets you stop and start the Engine and deploy projects from the simple (ok - somewhat simple) Oracle BPM Process Administrator tool.
Hope this helps,
Dan

Connector for tomcat and j2ee

I have a login system created. It creates accounts into a mysql server at the moment. I want the users to be able to log in. I need the correct details in my "my-DB-plan.xml" file in order to be able to connect to the SQL server. Im not sur what to put in this file or whether im to use a server.xml file
Any Help.Please.

Our[b] login.html page is simple as follows:
<html><head><title>
J2EE SQL Security and Registry System Demo
</title></head><body>
<h1>LOGIN using Derby and J2EE declarative security!</h1>
<form method="POST" action="j_security_check">

</html>The connection is not made on the page but rather the username and password is authenticated by "j_security_check".
It's something to do with the my-db-plan.xml file I think, but I don't know if I'm to replace that file, change it or what..
It's setup for the Derby Database server rather than MySQL. I'm not sure how you'd change it. This login system we are using can be seen here: http://www-128.ibm.com/developerworks/opensource/library/os-ag-logreg2/

Anybody explain ABAP client and J2ee engine?

There are client 000,001,066.
But for J2ee Engine the client is in a different way.
What is the relationship of User data between ABAP client and J2ee Engine?
and tell me some inside about client copy? I have read some docs of help online, I 'd like more tech fact.

Hello Shen,
First ground rule: ABAP stack can support mutiple clients while JAVA stack supports only one client at one given time. In terms of user master data you can have 1:1 relationship between ABAP client and corresponding J2EE client provided there is connection between ABAP and UME which normally is there as it configured during installation. So if a user exists in client X in ABAP you can also view it in client X of J2EE.
Regarding client copy what type of client copy are you asking about?
Regards.
Ruchit.

Lift and stamp image adjustments inconsistently working

Just started playing with Aperture a few hours ago and seem to have intermittent problems lifting and stamping image adjustments. The manual has little info about lifting, beyond metadata, but sometimes I'm able to also lift image adjustments (color correction, crop, etc.). This was an advertised feature, so I assume the lack of info in the manual about lifting image adjustments is an oversight (or I am missing it). Unfortunately, I'm not usually able to lift image adjustments. They appear to be consistently availabel in the Lift HUD right after I make the adjustment to the image, but if I click away and then back, the adjustment is gone.
I think it has something to do with the tiny icons on the lower-right part of some of my images. The one I usually see when I make some adjustments is a small white box with a left and right arrow on top of each other. This typically indicates that something isn't synched in other programs, but I don't know what needs to be synched in Aperture. The adjustments remain on the image when I click away and then back to it so they appear to be sticking.
I've seen a couple of other icons show up in the lower right hand corner of images, but haven't been able to figure out what they mean. There doesn't seem to be mention of them anywhere in the Aperture documentation. Does anyone have a pointer or explanation of each of the icons' significance?

OK, I got a bit of an answer from the instructional DVD. In the Image Adjusting section, they talk about lift and stamp. The problem is that you can't just select the image in the image browser, you have to click on the rendered image to lift the adjustments. It looks like you can also do this by option-clicking on the thumbnails.
In the demo, though, they appear to lift and stamp a crop. I can't get anything other than color and luminance adjustments to show up in the list of possible adjustments to lift. Rotation, crop, etc. They're all ignored. Am I missing something?

J2SE and J2EE

what are the differences of J2SE and J2EE in terms of programming? I have used J2SE in developing java applets and standalone applications and now, I want to explore more with J2EE. I am reading articles and site regarding J2EE. But for you what is J2EE all about?.
Thanks!

To be frank, if you have to ask you don't need it. Learn most of what Java SE has and can do; then you'll have a sufficient knowledge base to understand and use Java EE as it's intended, on enterprise-level applications.
If you want more information read the documentation, as I don't care to digest it for you.
