How to include class file in applet

I would like to include a class file into my applet gui.
As it were like inserting an applet into an applet.
How do i make this happen?
I have made my interface in netbeans, is there an easy way for this?

to do that you have to call the your class constructor in the applet
same like as we do in main method ...
call it under the init method

How to include class files in no package?

hi,
I have a class file in a package called
pack.Test
and a class file not in a package called
Library
When I try to use Library from within pack.Test, it says theres no such class. I have my classpath setup correctly, and the files in the correct directories.
ie. on windows if %DIR% is the base directory then
%DIR%\Library.java
%DIR%\pack\Test.java
is how they are layed out.
Is there a way to get Library imported to pack.Test?
thanks,

What?!! It isn't considered legal to access a
root-level class from a higher level package?Well it's not now because your code won't compile, but
prior to 1.4 you could. I think the JLS has been
updated to say you can't import from the unnamed
namespace.Hmm! I must have missed that bit (not that I read it in any great detail, anyway!). I suppose it forces you to use packages, which is a good thing, IMHO.
What I was wondering about was, is the directory structure of classes strictly necessary, given that a class contains information on its package anyway? I know some IDEs don't require the source files to be in the right directory - they will check on the package statement, and locate the class file accordingly - but is it absolutely necessary for class files to be located according to their directory structure? I know the JLS says they have to be, but could the JLS be relaxed on this point, without breaking anything?

How to include .jar files in coldfusion code

To Integrate our cfm code with paypal jar files we do the
following steps with our local coldfusion server ,and to run and
integrate the paypal Java SDK jar files, I think we need to do the
same process on the server, can you suggest any thing to do the
following setting for my domain on the server, without setting the
class path in coldfusion administrator.
The ColdFusion application server must be configured to know
the location of the PayPal JAR
files, and your ColdFusion Markup (CFM) pages must be
configured with the absolute path to
the PayPal API certificate for the PayPal API user on whose
behalf the calls are made.
1. Install the PayPal Java SDK “Installing the
SDK”.
2. Copy a subset of the Java SDK JAR files to a location
accessible by the ColdFusion
application server. The JAR files are in SDK_root\lib and
their exact names are as
follows:
– bcmail-jdk14-128.jar
– bcprov-jdk14-128.jar
– paypal_base.jar
– paypal_stubs.jar
sax2.jar
– xerces.jar
– xpp3-1.1.3.4d_b4_min.jar
– xstream.jar-1.1.3.jar
3. With the ColdFusion Application Server Administrator, add
the absolute path of the
location you determined in Step 2 to the Java and JVM
CLASSPATH environment variable.
4. Restart the ColdFusion Application Server.
Suggest me how to include .jar files without setting
classpath.

> Suggest me how to include .jar files without setting
classpath.
Copy them to {CF_HOME}\lib, where {CF_HOME} is, for example,
C:\CFusionMX7. Restart Coldfusion.

How to include .js file into validater-rules.xml

iam doing project using struts.
i have .js file for client side validation.how to include .js file into struts validate-rules.xml so that i can use those validation in my project.
without writing any class.
is there any way

copy + paste from my book...............
Enabling Client-Side Validations
In addition to providing a framework for simplifying server-side form data validations, Validator provides an easy-to-use mechanism for performing client-side validations. Each validation routine defined in the validator-rules.xml file optionally specifies JavaScript code that can be run in the browser (client side) to perform the same validations that take place on the server side. When run on the client side, the validations will not allow the form to be submitted until they have all passed.
To enable client-side validation, you have to place the HTML Tag Library's javascript tag in each JSP for which you want validation performed, as shown here:
<html:javascript formName="logonForm"/>
The javascript tag requires that you use the formName attribute to specify the name of a <form> definition from the validation.xml file, as shown here, for which you want validations performed:
<form name="logonForm">
<field property="username" depends="required">
<arg0 key="prompt.username"/>
</field>
<field property="password" depends="required">
<arg0 key="prompt.password"/>
</field>
</form>
All the validations that you have specified for the <form> definition to run on the server side will be run on the client side.

How to include external files in JSP

hi,
How to include external files like image or javascript in to jsp pages.
I am using MVC frame work. So i have to use request dispatcher. While calling the pages trough dispatcher the external files are missing from the output. Also am using tomcat as server,web.xml(deployment descriptor ) is also configured.
regards
sree

When you use the request dispatcher, the relative path for all your ressources becomes the relative path of your calling serlvet and not the JSP/servlet that you call. Make sure to use the full relative path such as:
/PATH_TO_YOUR_DIRECTORY/myRessource.ext
NOT
SOME_DIRECTORY/myRessource.ext

How to include the file name as an XML field

Hi,
I'm using a file adapter for process a flat file and convert it into an XML. Does anybody knows how to include the file name into an XML field.
Ex.
I process the file named <b>XXIMN21022007.txt</b> and I need an XML like:
<MT_FILE>
<field1></field1>
<field2></field2>
<field3></field3>
<filename><b>XXIMN21022007.txt</b></filename>
</MT_FILE>
Regards
Gonzalo

Just go for dynamic configuration.
Check the sender file adapter to write the filename in the header (as explained in Michal's blog) and then read that header in some mapping.
U can use that even in simple message mappings.
http://help.sap.com/saphelp_nw2004s/helpdata/en/43/03612cdecc6e76e10000000a422035/frameset.htm
Your code for the filename tag would be something like:
<i>DynamicConfiguration conf = (DynamicConfiguration) container
    .getTransformationParameters()
    .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create(
    http://sap.com/xi/XI/System/File,
    FileName);
return conf.get(key);</i>

How to convert class file

Hi all, I am new in java card development.
This is my environment setting:
@echo off
set JC_HOME=C:\JavaCard\java_card_kit-2_2
set JAVA_HOME=C:\j2sdk14103
set PATH=.;%JC_HOME%\bin;%PATH%
I have created the Wallet applet according to 'Zhiqun Chen" text book and named it WalletApp.java.
I have compiled this file to a class file.
This is where is I saved my file
C:\JavaCard\java_card_kit-2_2\samples\src\com\sun\javacard\samples\WalletApp\WalletApp.java.
But I don't really understand how to convert the class file.
May I know what is this for?

com.sun.javacard.samples.HelloWorld
0xa0:0x0:0x0:0x0:0x62:0x3:0x1:0xc:0x1 1.0
must save this in what file?
I tried to type in the command line below (and the result):
C:\JavaCard\java_card_kit-2_2\samples>converter -config scr\com\sun\javacard\sap
les\Wallet\Wallet.opt
error: file scr\com\sun\javacard\saples\Wallet\Wallet.opt could not be found

OR
converter -config <filename>
use file for all options and parameters to converter
Where options include:
-classdir <the root directory of the class hierarchy>
set the root directory where the Converter
will look for classes
-i support the 32-bit integer type
-exportpath <list of directories>
list the root directories where the Converter
will look for export files
-exportmap use the token mapping from the pre-defined export
file of the package being converted. The converter
will look for the export file in the exportpath
-applet <AID class_name>
set the applet AID and the class that defines the
install method for the applet
-d <the root directory for output>
-out [CAP] [EXP] [JCA]
tell the Converter to output the CAP file,
and/or the JCA file, and/or the export file
-V, -version print the Converter version string
-v, -verbose enable verbose output
-help print out this message
-nowarn instruct the Converter to not report warning messages
-mask indicate this package is for mask, so restrictions on
native methods are relaxed
-debug enable generation of debugging information
-nobanner suppress all standard output messages
-noverify turn off verification. Verification is default
*********************************************************May I know What is the correct command line to convert the class file and what must I do to before converting the class file?
I saw some article saying we must use JDK1.3, is it a must?
Your solution is highly appreciated.
Thank you!

Hi Ricardo,
I saved the file below as WalletApp.opt in the directory of scr\com\sun\javacard\samples\WalletApp

How to include ojdbc.jar with applet in apex

Hi,
I am integrating applet with apex. I need to use ojdbc.jar to connect to Database. How can i include this jar. I tried uploading it as a static file. But i am not sure how to embed it with applet code in region source of a page. I am using following code to embed the applet.

</applet>
Please suggest how to include the ojdbc.jar.

Thank you all for help, from your posts I was able to get the datepicker working with a different version of jQuery (but not jQueryUI) included on the page. There are two methods:
1. Include the new library before #HEAD# and change the reference to a different variable, for example:
<script src="jquery-1.6.4.min.js" type="text/javascript"></script>
<script type="text/javascript">
var jq164 = jQuery;
</script>
#HEAD#2. Include the new library after #HEAD# and enable noConflict() mode, for example:
#HEAD#
<script src="jquery-1.6.4.min.js" type="text/javascript"></script>
<script type="text/javascript">
var jq164 = jQuery.noConflict(true);
</script>In both examples above, $, jQuery and apex.jQuery point to apex jQuery, while jq164 points to the new one.
However, I couldn't manage to include a newer version of jQueryUI. I only found a page ([url http://stackoverflow.com/questions/6358961/using-multiple-jquery-ui-versions]http://stackoverflow.com/questions/6358961/using-multiple-jquery-ui-versions) that says you have to specify a different context for each version of jQueryUI included on the same page. I haven't yet had time to look at this, so if anyone already knows how to do it, it would be really nice to share it with us.

Using class files with applets

I've converted a college project, a calculator, into an applet for a website resume. When the html file that loads the applet is opened on a machine with a JVM, the applet works fine. When I tested it on a machine that doesn't have a JVM, the applet wouldn't open.
I'm assuming its because I'm using methods from classes such java.math, java.awt and java.awt.event. I wanted to try to include the neccessary class files into a .jar file that could be included into the archive attribute. Would this work? and also, where can I actually find these files so that I can put them into a jar file. For example, which directories would I look at to find them? I'm on Mac OS 10.3.7.
Even with a search utility,I can't find the specific files with I'm looking for.
Any help is greatly appreciated

Hi,
It doesn't matter that you have used classes in the packages java.math etc. The application will never run if there isn't a JRE installed for the web browser. I think most people usually puts a script on the html page which detects if a JRE is installed, and directs users to the download page if there is no JRE.

How to call class file from jsp without creating packages

i m using tomcat 5.5
i stored my class file into WEB-INF\Class directory
how to call that class file. from my jsp page.
i got some error.
i used package concept,that works fine.

i m using tomcat 5.5
i stored my class file into WEB-INF\Class directory
how to call that class file. from my jsp page.
i got some error.
i used package concept,that works fine.Then use packages.
As of Java1.4, you can no longer import classes from the default package (no package declared) into classes that are packaged.
All Tomcat classes are in packages, including the compiled JSP.
Therefore: Your classes need to be in a package inorder to be imported and used by the JSP.
Why the problem? If you know it works with packages, why try not to use them?

Does anyone know how to set policy file, so applet can connect other host?

I have an signed applet, it may connect to other host.
The applet should display a HTML pages, which may contains image tag points to a picture stored anywhere. I use a JTextPane to display this HTML page, but when it is loaded. a error occurs.
java.lang.SecurityException

at sun.awt.image.ImageFetcher.run(Unknown Source)
I have those kind of error (connection refused) before I signed my applet and write policy file to granr socketpermission to the codebase of my class files. But this error still occurs. I suppose it is because the sun.awt.image.* is Java standard class, so my policy file has no effect on them. But how can I make it works?

you need to install the jre, and place the win32.dll at JavaSoft\JRE\1.3.1_06\bin, that properties file place at JavaSoft\JRE\1.3.1_06\lib, comm.jar at JavaSoft\JRE\1.3.1_06\lib\ext\

and yet u need to signed the applet
1. Compile the applet
2. Create a JAR file
3. Generate Keys
4. Sign the JAR file
5. Export the Public Key Certificate
6. Import the Certificate as a Trusted Certificate
7. Create the policy file
8. Run the applet
Susan
Susan bundles the applet executable in a JAR file, signs the JAR file, and exports the public key certificate.
1. Compile the Applet
In her working directory, Susan uses the javac command to compile the SignedAppletDemo.java class. The output from the javac command is the SignedAppletDemo.class.
javac SignedAppletDemo.java
2. Make a JAR File
Susan then makes the compiled SignedAppletDemo.class file into a JAR file. The -cvf option to the jar command creates a new archive (c), using verbose mode (v), and specifies the archive file name (f). The archive file name is SignedApplet.jar.
jar cvf SignedApplet.jar SignedAppletDemo.class
3. Generate Keys
Susan creates a keystore database named susanstore that has an entry for a newly generated public and private key pair with the public key in a certificate. A JAR file is signed with the private key of the creator of the JAR file and the signature is verified by the recipient of the JAR file with the public key in the pair. The certificate is a statement from the owner of the private key that the public key in the pair has a particular value so the person using the public key can be assured the public key is authentic. Public and private keys must already exist in the keystore database before jarsigner can be used to sign or verify the signature on a JAR file.
In her working directory, Susan creates a keystore database and generates the keys:
keytool -genkey -alias signFiles -keystore susanstore -keypass kpi135 -dname "cn=jones" -storepass ab987c
This keytool -genkey command invocation generates a key pair that is identified by the alias signFiles. Subsequent keytool command invocations use this alias and the key password (-keypass kpi135) to access the private key in the generated pair.
The generated key pair is stored in a keystore database called susanstore (-keystore susanstore) in the current directory, and accessed with the susanstore password (-storepass ab987c).
The -dname "cn=jones" option specifies an X.500 Distinguished Name with a commonName (cn) value. X.500 Distinguished Names identify entities for X.509 certificates.
You can view all keytool options and parameters by typing:
keytool -help
4. Sign the JAR File
JAR Signer is a command line tool for signing and verifying the signature on JAR files. In her working directory, Susan uses jarsigner to make a signed copy of the SignedApplet.jar file.
jarsigner -keystore susanstore -storepass ab987c -keypass kpi135 -signedjar SSignedApplet.jar SignedApplet.jar signFiles
The -storepass ab987c and -keystore susanstore options specify the keystore database and password where the private key for signing the JAR file is stored. The -keypass kpi135 option is the password to the private key, SSignedApplet.jar is the name of the signed JAR file, and signFiles is the alias to the private key. jarsigner extracts the certificate from the keystore whose entry is signFiles and attaches it to the generated signature of the signed JAR file.
5. Export the Public Key Certificate
The public key certificate is sent with the JAR file to the whoever is going to use the applet. That person uses the certificate to authenticate the signature on the JAR file. To send a certificate, you have to first export it.
The -storepass ab987c and -keystore susanstore options specify the keystore database and password where the private key for signing the JAR file is stored. The -keypass kpi135 option is the password to the private key, SSignedApplet.jar is the name of the signed JAR file, and signFiles is the alias to the private key. jarsigner extracts the certificate from the keystore whose entry is signFiles and attaches it to the generated signature of the signed JAR file.
5: Export the Public Key Certificate
The public key certificate is sent with the JAR file to the whoever is going to use the applet. That person uses the certificate to authenticate the signature on the JAR file. To send a certificate, you have to first export it.
In her working directory, Susan uses keytool to copy the certificate from susanstore to a file named SusanJones.cer as follows:
keytool -export -keystore susanstore -storepass ab987c -alias signFiles -file SusanJones.cer
Ray
Ray receives the JAR file from Susan, imports the certificate, creates a policy file granting the applet access, and runs the applet.
6. Import Certificate as a Trusted Certificate
Ray has received SSignedApplet.jar and SusanJones.cer from Susan. He puts them in his home directory. Ray must now create a keystore database (raystore) and import the certificate into it. Ray uses keytool in his home directory /home/ray to import the certificate:
keytool -import -alias susan -file SusanJones.cer -keystore raystore -storepass abcdefgh
7. Create the Policy File
The policy file grants the SSignedApplet.jar file signed by the alias susan permission to create newfile (and no other file) in the user's home directory.
Ray creates the policy file in his home directory using either policytool or an ASCII editor.
keystore "/home/ray/raystore";
// A sample policy file that lets a JavaTM program
// create newfile in user's home directory
// Satya N Dodda
grant SignedBy "susan"
permission java.security.AllPermission;
8. Run the Applet in Applet Viewer
Applet Viewer connects to the HTML documents and resources specified in the call to appletviewer, and displays the applet in its own window. To run the example, Ray copies the signed JAR file and HTML file to /home/aURL/public_html and invokes Applet viewer from his home directory as follows:
Html code :
</body>
</html>
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
width="600" height="400" align="middle"
codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,1,2">
<PARAM NAME="code" VALUE="SignedAppletDemo.class">
<PARAM NAME="archive" VALUE="SSignedApplet.jar">
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
</OBJECT>
</body>
</html>
appletviewer -J-Djava.security.policy=Write.jp
http://aURL.com/SignedApplet.html
Note: Type everything on one line and put a space after Write.jp
The -J-Djava.security.policy=Write.jp option tells Applet Viewer to run the applet referenced in the SignedApplet.html file with the Write.jp policy file.
Note: The Policy file can be stored on a server and specified in the appletviewer invocation as a URL.
9. Run the Applet in Browser
Download JRE 1.3 from Javasoft
good luck! [email protected]

How to convert class file into exe

I don't knw wat to do.Netbeans creates the .jar file for you,
Simply right click on the project node in nb and select
clean and buildnext goto the location of the project
Eg:
C:\Documents and Settings\raghu0007\My Documents\NetBeans Projects\SimpleCalculcator\dist\There will usually be 2 files in there, 1 for the Gui parts and the other(.jar) the rest.
These two files must always be together (same directory for the jar file to work)
copy the dist folder to C:\Program Files\, Rename it and create a shortcut to the simplecalci.jar file
If you know the above just take a look at how you modified the MANAFEST file and the file(MF,class...) locations in the .jar
