JDeveloper and other Oracle JAR files with antivirus on access scanning

Hi
concerns in our IT department about security means that the AV software scans jar files on our client PC's and servers. This means that JDeveloper starts very slowly, even on a 3.2GHz PC. Can anyone tell me how to get around this or at least which jar files I could ask them to exclude from scanning? Also, will this affect running of our 10g Database and tools on the server?
Much appreciated
Peter - [email protected]

I've observed this problem with certain AV tools. Some fare much better than others (inside Oracle, we use Symantec AV and I see very little slowdown even when it's scanning jar files in jdev's install directory).
You didn't mention which version of jdeveloper you're using. Assuming 10.1.3 preview, the directories to exclude from scanning would be either the whole of your jdev install directory, or if you must be more selective, something like:
%JDEVHOME%/jlib
%JDEVHOME%/jdev/lib
%JDEVHOME%/ide/lib
%JDEVHOME%/jdev/extensions
%JDEVHOME%/lib
Would be a good start. These directories contain the bulk of the jars loaded at IDE startup.
Thanks,
Brian

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):

How do you create a jar file with txt and classes?

Hey, I'm trying to create code to create a jar file with a text file, but I can't figure out how to add the text file. Here is what I have so far:
try {
            // Name of jar file to write
            String archiveFile = "test.jar";
            Manifest jman = new Manifest();
            try {
                // Create a manifest from a file
                //InputStream fis = new FileInputStream("manifestfile");
                //Manifest manifest = new Manifest(fis);
                // Construct a string version of a manifest
                StringBuffer sbuf = new StringBuffer();
                sbuf.append("Manifest-Version: 1.0\n");
                sbuf.append("Ant-Version: Apache Ant 1.7.1\n");
                sbuf.append("Created-By: 1.5.0_19-137 (Apple Inc.)\n");
                sbuf.append("Main-Class: Main\n");
                sbuf.append("Class-Path: lib/swing-layout-1.0.3.jar\n");
                sbuf.append("X-COMMENT: Main-Class will be added automatically by build\n");
                // Convert the string to a input stream
                InputStream is = new ByteArrayInputStream(sbuf.toString().getBytes("UTF-8"));
                // Create the manifest
                jman = new Manifest(is);
            } catch (IOException e) {
            FileOutputStream stream = new FileOutputStream(archiveFile, true);// archive file is jar file name
            JarOutputStream out = new JarOutputStream(stream, jman);
            out.putNextEntry(new JarEntry("test.txt"));
            out.closeEntry();
            out.close();
        } catch (Exception ex) {
        }It creates the .jar file with the correct manifest but I can't get it to write the test.txt or anything else into the jar file.

Alright, my question has changed. Here's the code:

            Manifest jman = new Manifest();
            try {
                // Create a manifest from a file
                //InputStream fis = new FileInputStream("manifestfile");
                //Manifest manifest = new Manifest(fis);
                // Construct a string version of a manifest
                StringBuffer sbuf = new StringBuffer();

                // Convert the string to a input stream
                InputStream is = new ByteArrayInputStream(sbuf.toString().getBytes("UTF-8"));
                // Create the manifest
                jman = new Manifest(is);
            } catch (IOException e) {
            FileOutputStream stream = new FileOutputStream(archiveFile, true);// archive file is jar file name
            JarOutputStream out = new JarOutputStream(stream, jman);
            out.putNextEntry(new JarEntry("test.txt"));
            out.write("Hi".getBytes());
            out.flush();
            out.closeEntry();
            out.close();
        } catch (Exception ex) {
            JOptionPane.showMessageDialog(this,ex.toString(),"BUG!",JOptionPane.INFORMATION_MESSAGE);
        }It creates the jar file with the txt file inside it, but I can't write "Hi" inside of the text file. Any ideas?

Packaging jar file with classes

Hi experts,
I want to clarify a problem in relation with packaging .class files in jar file making
it jar executable.I was able to achieve this when number of classes are limited and confined to only a single program.However recently i developed a software
which is very much like SQL*Plus and retriee my company database using screen buffer management and i have handled almost all the issues.
But so long to execute this program i am typing
java <Program name>.It is using Oracle as backend.
I tried to package Oracle driver files in jar using
jar -cmf manifest.mf sqlpad.jar *.class Oracle\
where Oracle directory contains all the class files in separate folders like
Oracle\javax etc
I get a jar file with hefty MBs size.It is executable too.But when i try to connect to
database, i get message Oracle driver class is not found.
In what way should i package it as jar file ?

I wouldn't add the drivers to the JAR itself. Instead, I'd suggest one of the following:
1.) Add classpath entries into your manifest file pointing to the drivers' JARs
2.) Create a batch file for starting that contains a call to "java -classpath ..."
3.) Add some way to your app to configure additional classpaths at runtime and use a URLClasssLoader (and a wrapper class for the driver for registering with the DriverManager) that loads the driver's class

How can I get a single jar file with NetBeans?

How can I get a single jar file with NetBeans?
When I create the project I get these files:
dist/lib/libreria1.jar
dist/lib/libreria2.jar
dist/software.jar
The libraries that have been imported to create the project are in separate folders:
libreria1/libreria1.jar
libreria2/libreria2.jar
libreria1, libreria2, dist folders are all located inside the project folder.
I added the following code to the build.xml:
<target name="-post-jar">
<jar jarfile="dist/software.jar">
<zipfileset src="${dist.jar}" excludes="META-INF/*" />
<zipfileset src="dist/lib/libreria1.jar" excludes="META-INF/*" />
<zipfileset src="dist/lib/libreria2.jar" excludes="META-INF/*" />
<manifest>
<attribute name="Main-Class" value="pacco.classeprincipale"/>
</manifest>
</jar>
</target>
Of course there is also the project folder:
src/pacco/classeprincipale.form
src/pacco/classeprincipale.java
Can you tell me what is wrong? The error message I get is as follows:
C:...\build.xml:75: Problem creating jar: archive is not a ZIP archive BUILD FAILED (total time: 2 seconds)

This is not a NetBeans forum, it is a JDeveloper forum. You might want to try http://forums.netbeans.org/. I also saw your other question - try looking in the New to Java forum: New To Java

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

ServiceBus java callout - how to pack the JAR file with libraries?

Hello
I want to use a Java Callout from a Service Bus flow.
What is the correct way to pack the JAR file with its nessecary libraries?
I tried different methods to pack my JAR, but yet, as though the Java runs perfectly from the Workshop (Eclipse) , when I am trying to use the exported Jar on the ServiceBus flow, it fails with an ClassNotFoundException.
I would really appreciate your advice here.
Thanks
Koby

Well.. Looking inside my exported JAR file, I got all of the files there inside, including the jar file containing the library.
What I'm trying to do is run a simple java program that connect through SSH and therefore use an SSH library.
On the workshop I got it as an imported library JAR. And it works perfectly there.
Any idea?
Here's the complete error I get:

How to run jar files with arguments?

Hi everybody,
Is it possible to run a jar file with arguments passed to its MAIN class?
If yes can you help me on how to do it?
Thanx

I am in complete agreement with FahleE. I'll refine it a bit.
On my machine (running RedHatLinux8.0) you can run the demos like this.
1. open a console window
2. go to the directory where the demo you wish to run, say, demo.jar, is located
for instance for the SwingSet2-demo
cd /usr/lib/java/demo/jfc/SwingSet2
3. run the jar file
java -jar demo.jar
In order to run it windows style, ie, launching by double clicking, save these lines in a file called
LaunchJar.sh
cd /usr/lib/java/demo/jfc/SwingSet2
java -jar demo.jar
where demo.jar is the jar file you want to run.
Right click on the LaunchJar.sh and go to the 'Properties' tab. Check the 'Execute' permissions for Owner/groups/others. You can also do the same thing by chmod command.
Now double-click on the LaunchJar.sh file: your application should be launched.
Palash.
Please Note: It is important to set the path variable to your JAVA_HOME directory....
Otherwise, instead of
java -jar demo.jar, you will need to use the full path to your JAVA_HOME/bin directory like:
JAVA_HOME/bin /java -jar demo.jar.
Where JAVA_HOME is the directory where you have installed java. Typically it is usr/java or usr/local/java

Problems creating a jar file with eclipse

"posted as well on the eclipse forum but who knows maybe some of you had same issue before"
Hi Developers.
My issue is this, i have some java files which i would like to export and use as .jar files.
All files contains classes, the files all ends with .java extention and are contained into a java project.
I've seen the Eclipse tutorial for this case which advise to use:
Click on project>Export>java>jar file>Save as("verkiezingen")>Location("desktop")
Indeed it seems successfull as i see on my desktop the .jar file and while exporting the final dialog box does not tell me "exported with warnings"
I then try to import the jar within a project like so:
Right click on project>Build Path> add external jar's>select jar
all good so far as i see the new item "Referenced package" under the usual "JRE system library"
If now, within the project i create a new class and start with import.verkiezingen;
it gives me an error message saying "The import verkiezingen cannot be resolved"
cant understand why, if i open the jar from the "Reference package" the classes are there.
I will paste the code of a class within the project i've tried to export initially as jar.
code:
public class StemmachineException extends RuntimeException {
     public StemmachineException(){
          super();
     public StemmachineException(String s){
          super(s);
code:
Thank you guys

does the class have a package 'verkiezingen'? I don't see the package statement in your source listing.
For that matter, is the class in a subdirectory 'verkiezingen' inside the jar?
btw 1: use code tags when posting code to prevent the forum from swallowing certain characters, and to make it far more readable
btw 2: boooooo to non-English class names :( I hope you don't get coworkers that don't speak Dutch.

Can't run .jar file with JavaSE

Hello.
I'm trying to run a .jar file with JavaSE Binary, just like I did with Windows. I Ctrl+Rclick and pick "Open with..." and there is no such option. I've been searching the whole day for a solution, I kept getting "Open Java Preferences... put on top of the list" and things like that. There is no "Java Preferences" in the Utilities folder, and nothing related to my problem in "Java Control Panel" in System Preferences. Yes, I have Java 7. I just need to run this file with Java. How?
Thanks in advance.

Max. allowed size of .jar file is 1MB.

How to run jar file with classpath?

Hi, all,
I have some package in my project, with which I have a java help jar file as classpath, when I run my project, I need the jh.jar file in directory /jar/jh.jar.
Now, I bundled all my class packages into a jar file, my.jar, together with the /jar directory. When i run my jar file with command:
java -jar my.jar
It tells me couldn't find javahelp class.
What shall I do? How can I create my jar file with the jh.jar?
Thanks in advance.

Thanks, hjembaek,

Create a complete jar file with jscreator

Please provide all details for creating a jar file with jscreator for this 77 year old puzzle creator

Hi,
I would suggest switching to NetBeans IDE. It allows for the following:
- Ability to run with latest JDK release
- Enabled with the latest Java technologies
- Support for a greater number of application servers
The following will help with migration (if you already have a project setup in Creator)
http://www.netbeans.org/kb/60/web/creator-migration.html
Also, the following article describes how to create and Distribute Executable JAR Files in NetBeans

Installing a JAR file with NAL

This is in reference to my previous message about trying to use NAL to get
to a URL with System Rights...
In addition to having to install Java to use our new webpage, there is a jar
file that has to get pushed out, too.
It's not available as an executable, but, is there anyway to push out a jar
file with NAL? Does it need to be run, or, just copied somewhere, and, if
so...where?
Thanks!

We have an AGFA Imaging system that puts digitized x-rays, CAT-scans, etc.,
up on a webserver, so that docs all over our hospital can pull them up and
look at them.
The previous system HAD to use the MSJVM, but, last Saturday they upgraded
the system (not really telling us the requirements ahead of time...<G>), and
it had to use the Sun JRE. Sooo....I had to setup an AppObj last Sunday to
push out Java to all workstations, so went to Java.com and downloaded the
latest version, 1.5.x
Well...of course they had to use a certain version, 1.4.1_01, and, it
wouldn't work with 1.5.x at all, so, I pushed that out, then it turned out
that they use a product from Germany (AGFA, you know) named JacoZoom, and a
jar file is asked to be run by the users when they first login to the
website, and, of course...you have to be an Administrator.
Our VA Security Managers like to over-protect us, so, the German site
hosting JacoZoom is blocked, and, rather than drive home and download what I
needed, I thought it would be easier just to push out the URL with System
Rights temporarily (you understand that by this time, Monday afternoon, all
our 400 doctors were up in arms because they couldn't view any images), and
then the trying to push the URL just didn't work.
Sooo...I drove home and got the JacoZoom product (had to buy it), which is a
large executable containing several JAR files when exploded, one of which
was the one that was being pushed out. Running the executable didn't do the
trick (not sure why), and the JAR wouldn't run, even manually, but, I
FINALLY found an email from another tech going through the same hassle, and,
all he did was push a different JAR file to the \lib\ext folder in the JRE
1.4.1_01 folder...and it worked.
I did that, and, it worked, and deployed it all over the building.
Welcome to my world--and, I'm not complaining, because with SMS (which we
have to run, but don't use), I'd still be configuring the deployment
package.
Thanks.
