Is it possible to open a Jar within Java code

Hey
I am just wondering if it is at all possible to get java to run a Jar within the code. So the Jar is my update to my program and I have got it downloading from my site using the java code but now i want the code to open it for the user so they don't have to double click in on. Is this possible?
Thanks

Sure. The java.util.jar package.
You might want to take a look at service providers:

Possible to have if statement within filters code?

Hi
I have some filters set up, and have assigned some global vars to them, which I then use in my Filters code to display the filters:
myText:Filters [globals.data.glow1, globals.data.stroke1, globals.data.shad1]
Works perfectly.
Now I want to assign a global var to each global filter var to determine if it should be shown or not. So...
globals.data.glow1On = true;
globals.data.stroke1On = true;
globals.data.shadOn = true;
... and then somehow incorporate these new vars into an if conditional to determine if the filter global vars get included in the myText:Filters code.
However, I cannot seem to code the if conditional into the myText:Filters code correctly.
I even tried seperating it out like so:
if (globals.data.glow1On = true) {myText:Filters [globals.data.glow1];
if (globals.data.stroke1On = true) {myText:Filters [globals.data.stroke1];
if (globals.data.shad1On = true) {myText:Filters [globals.data.shad1];
But Flash only makes the last filter true (kinda makes sense to me now why).
Is there a way to do it without having to make an if conditional with 7 permutations?
Cheers
Shaun

A: Possible to have if statement within filters code?

You are not coding the conditional properly. "=" is for assignment, "==" is for comparing equality.
if (globals.data.glow1On == true) {myText:Filters [globals.data.glow1];
if (globals.data.stroke1On == true) {myText:Filters [globals.data.stroke1];
if (globals.data.shad1On == true) {myText:Filters [globals.data.shad1];
Also, a conditional evaluates whether or not something is true, so for Boolean values you do not need to explicitly compare them...
if (globals.data.glow1On) {myText:Filters [globals.data.glow1];
if (globals.data.stroke1On) {myText:Filters [globals.data.stroke1];
if (globals.data.shad1On) {myText:Filters [globals.data.shad1];
Lastly, for what I see that you showed, the conditionals are all missing their closing brackets, and while you can use them, the brackets are not needed for single command conditionals...
if (globals.data.glow1On){ myText:Filters [globals.data.glow1]; }
if (globals.data.stroke1On){ myText:Filters [globals.data.stroke1]; }
if (globals.data.shad1On){ myText:Filters [globals.data.shad1]; }
OR
if (globals.data.glow1On) myText:Filters [globals.data.glow1];
if (globals.data.stroke1On) myText:Filters [globals.data.stroke1];
if (globals.data.shad1On) myText:Filters [globals.data.shad1];

Verifying signed Jar using Java code

Hi,
I have been looking for a way to verify signed or unsigned jar from java code.
I have to use the jar name and from here, I have to verify the digital signature. For this goal I have found some Java classes which can be useful for me. These classes would be JarEntry class, from which I could get the certificates. Signature class, whose methods let me verify the digital signatures, and Certificate class. I also found a class called SignedObject from I could get the signature data which the method getSignature (), but the problem here it is that I need a private key in the SignedObject constructor, which is not possible since I want to verify a signed jar which I am not able to know the private key, just public key. So, could anybody tell me how I could solve this problem?
My code would be some as shown below:
jar = new JarEntry (location);
          jarcertificates = jar.getCertificates();
          /* We should check all the certificates
          if (jarcertificates != null){
               for (int i=0;i<jarcertificates.length;i++){
                    sig.initVerify(jarcertificates);
                    sig.update(jar.getExtra());
                    sig.verify( DIGITAL SIGNATURE FROM JAR SHOULD BE HERE);
I guess that I have to use jar.getExtra () in order to get the data to put in Signature.update() method but I am not sure, am I wrong?
Thanks in advance

Here is some sample code to verify a jar file:
        JarFile jf = new JarFile(args[0], true);
        byte[] buffer = new byte[8192];
        Enumeration e = jf.entries();
        ArrayList entries = new ArrayList();
        while (e.hasMoreElements()) {
            JarEntry je = (JarEntry) e.nextElement();
            entries.add(je);
            InputStream is = jf.getInputStream(je);
            while (is.read(buffer, 0, buffer.length) != -1) {
                // we just read. this will throw a SecurityException
                // if a signature/digest check fails.
            is.close();
        }To validate the certificate chain, you can call JarEntry.getCertificates(), create a CertPath from the array of Certificates (using a CertificateFactory), and then use the CertPathValidator APIs. For more information, see the PKI Programmer's guide: http://java.sun.com/javase/6/docs/technotes/guides/security/certpath/CertPathProgGuide.html

Executing jar from java code, then kill parent java code

Please suggest if there is any best way around on executing jar from java code then killing parent java code.
a) I have desktop based java application say "Monitor.java" which runs every 5 minutes.
b) How can I START external java application say "execute.jar" from Monitor.java THEN EXIT Monitor.java
I tried various options using "ProcessBuilder" and calling bat file but I need Monitor (parent application to EXIT, immediately after calling child (execute.jar)
Try1) ProcessBuilder builder = new ProcessBuilder("java -jar execute.jar");
Process process = builder.start();
Try2) Runtime r = Runtime.getRuntime();
Process p = null;
p = r.exec(new String[] { "cmd", "/c", "start C:/temp/Test.bat" });

I have a requirement to transfer data from one db to another db from Java Application Layer.Maybe, maye not. We get all sorts of weird "requirements" - which are nothing but thoughts or proposed solutions.
But,
Did the "requirement" mention whether the table existed already or not in the target database? - If not, did it tell you to create it - drop/create it?
Did the "requirement" deliver some explanation to why this copying was neeeded? - Are we talking replication? - Or a one time cloning?
Etc, etc,
Personally I would always argue against a "reuirement" like that. - It just isn't the way to do it. Period.
Regards
Peter
P.S: If you are satisfied with what COPY does, then you could let Java make an OS call and do it from there?

Signing Jars from within Java Code

Hi,
I would like to sign a jar file from within my Java code. Reason for this is that I wish to update a jar file at runtime, throw away the class loader that loaded the jar, and load the updated code inside a new classloader.
One problem, however: The jar file has to be signed before loading it. How can I do this from my Java program? Or do I need to have the jarsigner tool available at the location where I resign the jar?
Thanks in advance,
Ronald.

Hi,
In the meantime I found an answer to my problem. In rt.jar there exists a class sun.security.tools.JarSigner, which can be used for exactly this purpose. Not completely portable, but it'll do the trick.
Ronald.

Is it possible to use iFS API within java stored procedure?

question:
is it possible to use the iFS API for file handling
within a java stored procedure (which is invoced by a trigger)?
is there an "elegant" workaround if it is not possible?
problem:
my java code using the iFS API works fine outside
the java stored procedure
but invoked via trigger as java stored procedure
it throws following exception:
IFS-20102: Unable to start service (IfsDefault)
i am using:
oracle 9.0.1

thanks for your help
i looked through the applications developers guide
the basics behind advanced queueing (as far as i understand) is:
program A inserts a message into the queue - and program B gets message from the queue and processes it
question 1:
but what is the difference between advanced queuing and a queue i create by myself
(simply with a database table) and let application B (which runs in a loop)
check if the queue is filled
or am i missing something important which makes advanced queuing more practicable for my problem?
question 2:
you wrote about advanced queuing support in iFS 9.0.3, but the newest version i found was iFS 9.0.2
did you reffer to the advanced queuing mechanism in general or to a spezial queuing feature in iFS 9.0.3?
thanks

Shell script doesnot execute within java code

I have the following code

int c;
while ((c = shellIn.read()) != -1) {System.out.write(c);}
// close the stream
try {shellIn.close();} catch (IOException ignoreMe) {}

Currently when I run the above, the script runs and holds the input, I tried passing "&" to the command1 string as well as concatenating it to the exec arg but seems like the test.sh script then fails since it takes that as a parameter.Read the traps article.
So can I run the above script via the java code and let it run as a background process?Read the traps article.

Open new window using java code and not in script

i need some method like sendredirect or forward . where i can make some codes so as to open a new window.
actually i am calling a jsp from one jsp file where a lot of dynamic parameters are sent. and in the second jsp i call a servlet which works to download a file to the client side. i want the file should open in new window not in the browser from where it is initiated.
else can any one say the mime type where i can open file(a xls file) in xls window and not in browser which is not needed as user needs to press the back button(present in browser)

Hi,
in your code
the following code, which is used to set the file name that is to be downloded
response.setHeader("Content-Disposition", "*inline*; filename=somename.xls" );
to be replaced by
response.setHeader("Content-Disposition", "*attachment*; filename=somename.xls" );
it will work fine try it.

Execute PL/SQL block with named binds from within java code?

Hi guys,
Is there any good way to execute my PL/SQL code, for example
BEGIN         :x := :x+1; END;
from my Java code? I need nothing complicated, just static code block with named binds.
I have tried the Oracle exetnded JDBC (setXXXbyName methods):
public static void main(String[] args){     try {     Class.forName("oracle.jdbc.driver.OracleConnection");     Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","user","password"); String SQL="begin :x:=:x+1; end;"; OracleCallableStatement stmt; stmt=(OracleCallableStatement)conn.prepareCall(SQL); stmt.setIntAtName("x", 5); stmt.registerOutParameter("x", Types.INTEGER); stmt.execute(); System.out.println(stmt.getInt("x"));     } catch (Exception x) { x.printStackTrace();    }   }
And get the java.sql.SQLException: operation not allowed: Ordinal binding and Named binding cannot be combined!
Then i've tried SQLJ appoach:
public static void main(String[] args){     try {     Class.forName("oracle.jdbc.driver.OracleConnection");     Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","user","password");       Oracle.connect(conn);       System.out.println("Connected!");           int x=3;       #sql { BEGIN         :x := :x+1;       END; };           System.out.println("x=" + x);     } catch (Exception x) { x.printStackTrace();    }   }
And x=3 had retuned... Although 4 expected.
Then, I've set parameter sqlj.bind-by-identifier=true
And result is another exception! java.sql.SQLException: Missing IN or OUT parameter at index:: 2
Can you please mark my mistakes/point to correct solution?
Thanks in advance,
Alexey

Izzit possible to do reverse engineering in java code

the program will able to read the source code and draw a class diagram from the specified source code

usually you would start off with a class diagram (during the design phase) and then write the code (during the implementation phase). But if you start off with the code and then create a class diagram, then I would call it reverse engineering.
Rational Rose and Together do just that.
