NO Client side JAVA

I need to develop a JSP that contains no client side JAVA.
By making use of JSP Bean Actions - would this not be considered using client side Java?
Any other adice on creating a JSP without using any client sode Java would be greatly appreciated.
Thank you very much in advance.

Hi
Thats right, JSP contain Java Code or References to Java Objects which are all resolved on the server side and the output is sent to the client (browser).
The page could contain client side java if you embed Java Applets into your JSP.
I'm not sure if you mean that you don't want to have any "Java Code" in your JSP, such as :
<% if()......%> etc. then you have to go for Custom Tag Libraries and Java Bean Components.
See the links below for help on these:

Good Luck!

FRM 92091 unexpected fatalerror in client-side Java code

Hi to all ..
I have a Forms/Reports Application in a form I have a Java Bean that get the username of the client PC
In the Oracle AS 10g all work fine in a Weblogic I get the error
FRM 92091 unexpected fatalerror in client-side Java code
and in the details of the error
java.security.AccessControlException : access denied (java.utils.PropertyPermission user.name read)
any Idea ????
Thank's in advance

Hi there
I am having a similar problem. We have a weblogic server which runs our forms application.
We were able to access the forms without any problem until when at one point, when we choose a different module in the form, we hit the below error
FRM92091 : unexpected fatalerror in client-side Java code
This is the details
Java Exception :
java.lang.SecurityException:class "oracle.forms.ui.DropDownEvent"'s signer information does not match signer information of other classes in the same package

After the above error, the user restarted the PC, and the problem is gone. If this was an issue with the access right to the directory, how come after restart the PC, the form was working fine. Hope to hear some feedback and thank you in advance.

Calling client-side Java?

Is there a way to call a client-side java class from
ActionScript? Server-side is clearly available, but I'd like to do
some expensive processing locally.
Thanks

The Flash Player security sandbox virtually prohibits access
to any client-side resources whatsoever.

Hi am new and need help on client side java.

Hi I am a .net developer. Dont boo lol. I am trying to find the latest on Java. I build web apps and would like to use java on the client side.
Is there a new form of java for client side code.
What do I need to install?
Where are some good sites that provide tutorials for Java newbies wishing to develop web client scripts etc.
Thanks

Is there a new form of java for client side code. Web apps usually use Java Server Pages, or JSPs, on the client side.
What do I need to install? Tomcat is a free servlet/JSP engine:

ThanksBetter buy a book. I highly recommend Hans Bergsten's JSP book for O'Reilly.

Changes in server side java file not reflecting in Client side java code?

Hi friends,
iam using eclipse IDE, JBoss server, SWING GUI and Oracle DB
( looks like : SWINGGUI (Client) <--> EJB's (serverside) <---oracle )
my problem is , when i make change in server side bean file, that changes are not reflecting in GUI programs.
(for ex: iam adding settr and getter for a field and using that in GUI program. but its not identifying that setter or getter).
please tell me what should i do for every change done to server side program, that should reflect / available to GUI?

my problem is , when i make change in server side bean file, that changes are not reflecting in GUI programs.
(for ex: iam adding settr and getter for a field and using that in GUI program. but its not identifying that setter or getter).what do you mean it's not "identifying" the methods?
you have to call those methods you know
are you getting NoSuchMethodError?
please tell me what should i do for every change done to server side program, that should reflect / available to GUI?you haven't posted any code or error messages that might help us debug

Client-Side Java Application accessing a database

Hello Sun Forums,
I'm developing a Java based client application which accesses a MySQL database server via JDBC.
My question is: How can I store the password for accessing the database in a secure way on the client? I'm looking for something like the Oracle wallet. I don't know if there is a solution to this problem. Any user could do reverse engineering and extract the password out of the source code. One way hash algorithms don't work either. Any help concerning this topic is highly appreciated.
Thanks, Yves

What you can do is to not make the DB visible by the end user and query only through request to a webserver. If you wish to adhoc type of queries, you can have a sql validation request, if your sql server supports that.
If you cannot use a webserver interface, then throw the idea out about saving the client password, the user is just going to have to enter their password. If you are worried about entering the password and cannot use a webserver, then you don't have a project.
Have the client call on the phone and request an extract, then send it to them on a DVD. But that can be intercepted in the mail. Even if it's encrypted, they have your data and eventually they will decrypt it.
BTW: security is only an illusion that lets us sleep at nights, in reality, it is nothing more than a hinderance: if someone really wants to access your web connected resource, then they are going to eventually find a way to do it.

Java.rmi.server.codebase=file:(?????); at client side: classnotfounexceptio

I'm trying to run an RMI application (under Windows XP, one machine for client and server) like this:
at server side:
java -Djava.rmi.server.codebase=file://\..\..\..\j\ -Djava.security.policy=file:.\polityka.txt sss
- and it works fine, but at client side:
java -Djava.security.policy=file:.\polityka.txt -Djava.rmi.server.codebase=file://\..\..\..\j\ kkk
results in:
Exception in thread "main" java.lang.NoClassDefFoundError: PrzykladowaKlasa
at kkk.main(kkk.java:31)
when I'm listing directory (at client side) got with System.getProperty("java.rmi.server.codebase") i get this
file://\..\..\..\j\
OdleglaKlasa_Stub.class
PrzykladowaKlasa.class
Folder Structure is:
|------j\
| |------(*_Stub.class, and ClassNeededByClient.class)
|------2\
| |------Server\
| | |------(serwer files)
| |------Klient\
| | |------(klient files)
I'm fresh in RMI and Codebase poperty, but with some exp with Java...
(policy files are allright - grant {permission java.security.AllPermission;};)
Any help will be appreciated.

I've come back to this issue again (since I am moving code around to different systems again). Using linux I can use -Djava.rmi.server.codebase=file://$PWD/build/
Presumably there is a similar command in WIndows.

Opening a Java Window from a jsp page on the client side

Hi all,
Thanks in advance to all who could help me for this problem.
I've written some jsp pages. In one of them, I open a new Java Window,
which is a simple Java Frame. If I test this directly on the Tomcat
server, everything works well.
But when I call the jsp page through a web browser of a distant client
(normal use), and when I want to see the java window, no window pops
up. It appears that the Java Window pops up on the server, and not on
the client side, which is what I wanted.
Could someone tell me how to make the Java frames appear on the client
side ? (Is it linked to the code or to the configuration of Tomcat ?)
Thanks in advance,
Alexis.

JSP always run on the server. On the client you only see the results.
But you can use applets on the client side: http://java.sun.com/docs/books/tutorial/uiswing/components/applet.html

ADF Faces + hardware device in the client side.( adf swing or adf java fx)

We are using adf+swing in desktop app.
We like ADF Faces but we need interations with Hardware device in the client side: scan reader, web cam, bar code reader, finger prints reader …
How to do that’s in the adf faces web environment ( what about with sandbox security) how to obtain in the adf faces web page in the client side de video streams.
In the future adf will be use Java FX?
Thanks
Juan Carlos Llanes

Hi,
see sample 71 http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html#CodeCornerSamples
You can use ActiveX plugins or JavaApplet to access the client system. To reach out of the sandbox, it will require a certificate
In the future adf will be use Java FX?
No.

Is XML-SQL Utility for Java run on Client Side?

A question about the XML-SQL Utility for Java
When a client program connect to a Oracle database (the clinet program and Oracle DB is run on two different machine. Oracle 8i is used) and use the oracle.xml.sql.query.OracleXMLQuery Class (form the XSU) to generate XML by given a SQL query. I want to know the transforation process is execute in the Clinet side or the database?
Is there any method that i can retrieve the XML directly from the database rather then doing the transformation form the Client side?

Set JDK_HOME to the directory where you install your JDK (Java Development Kit).
So instance, I've install JDK1.1.8 on my
C drive so
set JDK_HOME=c:\jdk1.1.8;c:\jdk1.1.8\bin

Client Side Rich Internet Applications in Java. Do we have support for it ?

What about the use of Java EE technologies on client-side ? The Java EE 5 specification lists different technologies: servlet, JSP, JSF, EJB, JTA, JDBC, JPA, JMS, JNDI, JavaMail, XML processing, JCA, JAAS, web services, JMX...
Almost all of them are used on the server side. What about building applications on the client side ?
Is Sun thinking too much hardware these days ? Why is that most of the products come out of 3rd party vendors like apache for instance ?

There's your fundamental problem... We KNOW from bitter experience that rich client app are NOT scalable. The world simply doesn't work that way.
Architecture starts from the foundations and works up. Computer systems achitectures start from the server and work out... We're just not out there yet dude.
My crystal ball says that within 20 years computers will be sooooo freeken fast that "scalable" really won't be an issue any longer, except for worldwide realtime massive transaction rate systems (like VR role playing games)... so enterprise solutions will naturally migrate back towards the desktop.
In the meantime the kids are having fun on the desktop and us "boring backend people" collect $40 million dollars in twenty minutes with rock-solid server-side solutions. Horses for courses. Watch for pitch reports.

Java Stored Procedure / connection JDBC / Server Side / Client Side

Hi,
I would like to know if we can know at the runtime with a JDBC api if the stored procedure is running in client side or in server side ?
THANKS

You wrote
"Java stored procedures -- by definition - are stored in the 8i rdbms. !!"
From the Oracle8i Java Stored Procedures Developer's Guide
Release 8.1.5
A64686-01
"If you create Java class files on the client side, you can use loadjava to upload them into the RDBMS. Alternatively, you can upload Java source files and let the Aurora JVM compile them. In most cases, it is best to compile and debug programs on the client side, then upload the class files for final testing within the RDBMS"
This means that you can create shared classes that are used on both the client and server side. The source does not need to reside within the server (according to their documentation). Please also note the following from the Oracle8i JDBC Developer's Guide and Reference Release 8.1.5 A64685-01 for using the getConnection() method on the server:
"If you connect to the database with the DriverManager.getConnection() method, then use the connect string jdbc:oracle:kprb:. For example:
DriverManager.getConnection("jdbc:oracle:kprb:");
Note that you could include a user name and password in the string, but because you are connecting from the server, they would be ignored."
So if you're coding a shared class that is to run on both the client and server side, you might do something like this:
Connection conn =
DriverManager.getConnection(
System.getProperty("oracle.server.version") == null
? "jdbc:oracle:thin:@hostname:1521:ORCL"
: "jdbc:oracle:kprb:"),
"youruserid","yourpassword");
As stated earlier, the userid and password are supposedly ignored for server connections retrieved in this manner. I haven't tried this yet, but it is documented by Oracle.

Can php pass info to a java client-side program?

hi!
can a php script on a remote server (activated thru command line or whatever) pass data over the internet to a java client-side program? if so, how?

Not unless the Java program is listening on a known
port.

hii ,
I have this problem.
I have populated an array with records in jsp.The array is being populated correctly ..i hav check it .
Now I need to get back this array in client side in a java-script function.
I need this bcoz i need to check whether the value entered in a particular field in the form is there in the table before the form is submitted...hence the need of array.
Surprisingly in my java-script function i can get back the length of array,but as soon as i am writing something like arr[0] where arr is the name of array populated in server side using jsp,i am get scripting error.
i.e a code like
funtion partynamecheck()
var n=<%arr[0]%>
alert (n) ;
is giving scripting error.i.e showing error in page at the bottom left -side of browser.
but code like
funtion partynamecheck()
var n=<%arr.length%>
alert (n) ;
} is working fine.
Please help ..all wrk stuck.
Arnab

Hi,
i cann't help you with javascript, but the jsp-expression must have this syntax
var n=<%=arr[0]%>
Hope this help!
