VeriSign SSL signature used in JAR file?

Can the security key used for SSL be imported into Java to sign a JAR file?

Nope. You need a "code signing" certificate for java.

Using a JAR file as a project file

My application allows the user to create projects. Previously, a project file was simply an XML file. Now, a project file needs to also contain many images.
I thought it would be a good idea to simply use a JAR file as my project file.
Since I've really never really worked with JAR files and the java.util.Jar package directly, I have a few questions.
1) Would it be better just to simply store the images as binary in the XML file? I just spent a good amount of time making the XML file very readable so I thought it would be better to keep the images separate while still having a single "project" file.
2) Is there anything inherently wrong with the way I'm working with the JAR file in the code below?
Simple XML file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE project [
<!ELEMENT project (img+)>
<!ELEMENT img EMPTY>
<!ATTLIST img src CDATA #REQUIRED>
]>
<project>
     <img src="blah.jpg"/>
</project>

}Thank you!

1) I also think it's much better to keep your images separate from your XML, this prevents a lot of in case you just want to read XML data
2) What's exactly going wrong here? For the project.xml, make sure it's not inside a directory within the JAR file, or else the variable i will be null. Otherwise it looks fine..

Using a jar file in my application... how?

I have a JAR file which contains some classes I need to use in my application. I however, after looking in several books, cannot figure out how to use this JAR file within my application.
Do I simply put it in the directory with my .java files, and use an import command? I'm confused.

If the classes in the jar are part of a package then you can import them based on the package structure. The jar file will have to be part of your CLASSPATH variable.
i.e.
myUtils.jar
resides in C:\"My Classes"
CLASSPATH = .;"C:\My Classes";"C:\My Classes\myUtils.jar"
within the jar I have the following class:
\ameyer\Util\someUtil.class
\ameyer\Util\anotherUtil.class
To use these classes I could use the following import statement
import ameyer.Util.*;
This would import any class at that level in the jar.
Note: the import part of the CLASSPATH is "C:\My Classes\myUtils.jar"
hope this helps.

Gridworld Case Study - how to use a .jar file with textpad

Hello,
I am a student currently working on a project involving the Gridworld case study. While trying to work on my project at home, I discovered that I would get new "cannot find symbol" compiler errors that I had not previously gotten while compiling the same code at school. I am assuming this has something to do with the .jar file included in the gridworld code. How do I get textpad and/or the java compiler to find and use the .jar file and reccognise the classes which i am importing and extending in my project?
Thanks,
-Alex

Thanks, It works for compiler now.

How do we use our .jar file of Re-Usable Business Components in 11g?

Hi All:
We have developed a library of re-usable Business Components in 10g utilizing the instructions found here:
http://download-west.oracle.com/docs/cd/B31017_01/web.1013/b25947/bcadvgen007.htm
We are now planning on migrating to 11g, so we need to know how to implement this re-usable business component library.
Is it possible to use it as it stands created in 10.1.3.3?
Or do we have to migrate it over? And how is this done since we still have applications that use it in 10g?
Your input is very appreciated since this is an important step in our migration plan. Doing this correctly is crucial to our shop. We have been trying a few things, so far with no luck.
Thanks very muich.

Shay:
My colleague that received the errors is going to unexpectedly be off for a few days, so I tried to re-create the errors so that I could get back to you. What was essentially happening was that on certain tables, the first column was missing from the EntityImpl. These tables MIGHT be those that had a primary key that when JDev removed the underscore, had the same name as the Oracle table. For example the table name was ResidenceCode and the primary key of that table was Resident_Code and was found as the first column in the table. HOWEVER, when I tried migrating our reusable business components libarary .jar file, using 11.1.1.2.0, I did not experience the same errors, so I'll get back to you. She was perhaps using an older version of 11g?
But I do have one question. Can we use a .jar file of reusable business components built in 10g in 11g? As you can imagine, this library is being used in other applications, and we'd like to prevent having two copies, if at all possible. Because of all the structural changes, I am guessing we can't, but I'd really appreciate your reply.
I have found the documentation *36.7 Working with Libraries of Reusable Business Components* at http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/bcadvgen.htm#CHEFECGD with respect to 11g. If you know of any other 11g considerations with respect to this task, that would be great as well.
Thanks Shay, I really appreciate hearing from you.

I am unable to sign with Digital signature using a .PFX file. The button does not appear.

When I try to sign with a Digital signature using a .PFX file, the button to select the signature does not appear. I have JAVE SE 7 U11 10.11.2.21 platform in my add ons and JAVA Consol 6.0.33 and 6.0.35 in my extentions.
This problem is not encountered in Crome or IE-8

Regarding your first question about bookmarks, I think you discovered the answer in when you pressed the address bar. The second tab there has your bookmarks.
As for the keyboard, I'm not sure why your Firefox is reacting so slowly; mine seems to show keyboards even when I don't want them. If you have accumulated a lot of history, perhaps that's an issue?
Did you use any third party software to move your Firefox data from internal memory to the storage card?

Problem using misc jar-Files in Composite Application

Hi there,
I want to use different jar-Files in my Composite Application on SAP Netweaver 7.3.
I have created an external Lib DC where I have inserted the libs. After that I created an enterprise EAR and added the dependency to the PP of the external lib DC.
After that I added the a dependency to my CAF-EAR. But I cannot access the mehtods and functions from my jar files.
What's wrong there?
Another question: Is it possible to add the jar-files directly to my CAF-EAR without creating the external library DC and adding a dependency?
Any help would be greatly appreciated
Thanks

Hi, I've downloaded Jacob and got it running on my installation by doing the following:
1. Download http://danadler.com/jacob/jacobBin_17.zip.
2. Extract to Jdeveloper10g/jdev/lib/ext/Jacob
3. Copy jacob.dll to c:/windows/system32
4. Add JDeveloper10g/jdev/lib/ext/Jacob/jacob.jar to JDev user libraries, calling it 'Jacob'
5. Add the 'Jacob' library to the project.
6. Create a word document at c:/java/jacob/file_in.doc
7. Create a new class with the following code:
package view;
import com.jacob.*;
import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
public class TestJacob
public TestJacob()
* @param args
public static void main(String[] args)
TestJacob testJacob = new TestJacob();
testJacob.runTest();
public void runTest()
boolean tVisible = true;
String sDir = "c:\\java\\jacob\\";
String sInputDoc = sDir + "file_in.doc";
ActiveXComponent oWord = new ActiveXComponent("Word.Application");
oWord.setProperty("Visible",new Variant(tVisible));
Object oDocuments = oWord.getProperty("Documents").toDispatch();
Object oDocument = Dispatch.call(oDocuments, "Open", sInputDoc).toDispatch();

How to remove Jar signature in BouncyCastle jar file

I am using Ant to expand and create my jar file.
Any Ideas , I would like to remove the signature of the bouncycastle jar file.
thx in advance

It's actually not easy to do it. There are various regexp ways of doing it. If you search you'll find them. But they are only partial solutions. What you really need to do is write an HTML parser, perhaps using Java's built-in HTML parser. That's the only way to really and truly extract text from HTML. It's a bit of an advanced programming task, though.

Can I use a .jar file as a part of my program?

i.e. Can I import compiled classes from a .jar file.
I want some functions in the .jar file. Would this be ok? If yes, how? I tried to import them by a statement like this:
import com.something.otherthing.xxx;
But it doesn't work! My environment is JBuilder.
Thanks in advance.

If you want to use stuff in a jar, then add the jar to your classpath. Then use the import statement as you normally do (nothing special is needed there).

NoClassDefFoundError : when I am using MDM jar file

Hi All,
In my Webdynpro Java application, I need to acces the MDM Data. i have to use these jars,
mdm-data.jar
mdm-protocol.jar
mdm-admin.jar
mdm-common.jar
mdm-core.jar
MDM4J.jar
and i getting this Error, while deploying the application to server.
java.lang.NoClassDefFoundError: com/sap/mdm/net/ConnectionAccessor
I guess, the reason may be that I dont have these above JARs in the server.
Please give me a solution as soon as possible.
Thanks,
Boopathi.

Dear Bhoopathi,
You are getting classnotfound exception because, the external jar file you are using is available only at designtime (ie. Only in NWDS), and not available for runtime (ie. in J2ee server). To make it available in runtime, you have to deploy the jar file to J2ee server, so that the classes available in jar file will be available at runtime also.
If the project is a simple webdynpro project, then, copy the jar file in to lib folder of the project and add the jar file in build path of the project. When this project is deployed, the jar file will also be available along with project. But, this jar file will be available only for this webdynpro project.
If the project is a dc project, you have to deploy this jar file as a separate dc, and refer this dc in you dc project.
Since jar file cannot be deployed directly, we have to bundle this jar to ear file,as a library.Once this library dc is deployed, you can use the same library dc in other dc projects also.
For deploying external jar to J2ee engine, refer this link
Bid adieu to bots - using CAPTCHAs
I prefer this link, because it worked for me.
If it is not working, refer this..

How to run a java program using additional jar files

Hi everyone in the forum,
i ve created an app using the hFreeChart in eclipse, so i added them as external jar files and tested the program.
now my problem is that the program should run using a terminal in win and i do not know how can i do to make the command line or the system to find them, i added to the path but i read somtehing about classpath, but i have no idea. if anyone can help?
thanks in advanced

Actually, the best way to prepare a program for regular running is to make it an executable jar file, which means adding a manifest file which contains (at least) a Main-class: and a Class-Path: line. Referenced class libraries typically sit in a lib directory next to the java file. Then you can run it using java -jar myprog.jar.
Failing that create a batch file or link that supplied java with command line parameters including a -classpath=
Using the class path environment results in too much contention between competing values of it.

How to create and use library JAR files with command-line tools?

Development Tools -> General Questions:
I am trying to figure out how to put utility classes into JAR files and then compile and run applications against those JAR files using the command-line javac, jar, and java tools. I am using jdk1.7.0_17 on Debian GNU/Linux 6.0.7.
I have posted a simple example with one utility class, one console application class, and a Makefile:
http://holgerdanske.com/users/dpchrist/java/examples/jar-20130520-2134.tar.gz
Here is a console session:
2013-05-20 21:39:01 dpchrist@desktop ~/sandbox/java/jar
$ cat src/com/example/util/Hello.java
package com.example.util;
public class Hello {
    public static void hello(String arg) {
     System.out.println("hello, " + arg);
2013-05-20 21:39:12 dpchrist@desktop ~/sandbox/java/jar
$ cat src/com/example/hello/HelloConsole.java
package com.example.hello;
import static com.example.util.Hello.hello;
public class HelloConsole {
    public static void main(String [] args) {
     hello("world!");
2013-05-20 21:39:21 dpchrist@desktop ~/sandbox/java/jar
$ make
rm -f hello
find . -name '*.class' -delete
javac src/com/example/util/Hello.java
javac -cp src src/com/example/hello/HelloConsole.java
echo "java -cp src com.example.hello.HelloConsole" > hello
chmod +x hello
2013-05-20 21:39:28 dpchrist@desktop ~/sandbox/java/jar
$ ./hello
hello, world!I believe I am looking for:
1. Command-line invocation of "jar" to put the utility class bytecode file (Hello.class) into a JAR?
2. Command-line invocation of "javac" to compile the application (HelloConsole.java) against the JAR file?
3. Command-line invocation of "java" to run the application (HelloConsole.class) against the JAR file?
I already know how t compile the utility class file.
Any suggestions?
TIA,
David

I finally figured it out:
1. All name spaces must match -- identifiers, packages, file system, JAR contents, etc..
2. Tools must be invoked from specific working directories with specific option arguments, all according to the project name space.
My key discovery was that if the code says
import com.example.util.Hello;then the JAR must contain
com/example/util/Hello.classand I must invoke the compiler and interpreter with an -classpath argument that is the full path to the JAR file
-classpath ext/com/example/util.jarThe code is here:
http://holgerdanske.com/users/dpchrist/java/examples/jar-20130525-1301.tar.gz
Here is a console session that demonstrates building and running the code two ways:
1. Compiling the utility class into bytecode, compiling the application class against the utility bytecode, and running the application bytecode against the utility bytecode.
2. Putting the (previously compiled) utility bytecode into a JAR and running the application bytecode against the JAR. (Note that recompiling the application against the JAR was unnecessary.)
(If you don't know Make, understand that the working directory is reset to the initial working directory prior to each and every command issued by Make):

Using a jar file ?

I have a jar files called xerces.jar . I believe that jar files hold premade classes. I need to use some of these classes namely org.apache.xerces.parsers.SAXParser;
I was wondering how to I install this jar files in JBuilder. Someone in college did it before for me but I forget.
Thanks
Mick

Development tools (even JBuilder) come with this really COOL thing...it's called ONLINE HELP. (The giveaway is the HELP menu usually prominently displayed on the right of your menu)...try it. I guarantee you will find the answer to your question.

Using a Jar file into my jar project (Applet)

Hy,
I would like to know how I have to do to put a jar library in my jar file (containing my classes) ?
I use only 2 classes of that particular jar library (Regex.class & RegRes.class), and when I only put the jar file (patbinfree153.jar), the applet stops when its reaches the first line where i use this class.
this line :
Regex Mon_Regex = new Regex("(([<][iI][mM][gG][^>]+)[sS][rR][cC][=][\"]{0,1}([^\"> ]*))");However, it works when I launch the applet in AppletViewer, but doesn't work anymore when I create a jar file, and open it through my web browser. (I signed already my jar file, and it works until it reaches this line). That it to say that the jvm can find the 2 external classes when I run the program trough Eclipse, but can't find them when I create my package .jar. (I hope I am clear)
Do I need to extract the folders of this jar file ? Because I dont think the import works with those two classes. Or can I just put those 2 classes like my own classes, in this case, what to write for the import line ?
the import I do :
import com.stevesoft.pat.*;Thanks ^^

I think I found a beginnig of solution, but I still have trouble.
In the tutorial you gave me, it is said to add the following line in the manifest file to use jar in jar :
Class-Path: JAR-FILE.jar(here is the source : http://java.sun.com/docs/books/tutorial/deployment/jar/downman.html)
I did it, it works fine locally, but when i put my html, jar, files on my web site, my applet seams not to find the other jar file again.
Locally, the architecure is the following :
\upload4.html
\upload4.jar (its manifest have the class-path line linking with patbinfree153.jar)
\patbinfree153.jar (contains 2 classes I need)I uploaded the same architecture on my web site, but it doesn't work. The applet stops when it reaches the 1st line where I need one of the patbinfree153 classes.
Any idea ? :-)
