IE Specific problem loading signed applet java 1.5

Hello,
I am having troubles loading our signed applet under IE 6.0 (only tested version atm).
Firefox loads it without trouble, though the <object> tag that launches each is different.
Every time I try to launch the applet, it prompts me to install the java runtime environment. I currently have 3 different versions of the java 1.5 runtime on my machine and the Java Control Panel is set to default to the most recent (1.5.04).
Regardless of whether I choose 'Install' or 'Don't Install' a rectangle with a red X appears in the top left corner of the window. Nothing happens if I choose 'Install'. I did install through that prompt once. I don't know why it keeps asking me.
I have enabled the console before loading the applet, and there is absolutely NO output there. The applet is not loaded at all. I am not prompted to accept or deny our certificate. I have also tried disabling as much as I could security-wise in IE.
Any help would be greatly appreciated. I've been searching the net for 2 days and haven't come across anything that fixes this problem. Almost everything I have found has indicated at least some console output at least.
Here is the javascript code I am using. createVCRTarget is called on a button click. I guess I should also mention that this was working some months ago, but it is possible that it was before I installed Service Pack 2. All of my Windows security updates are installed. Also, you should be able to see in here that I also tried using an applet tag. That didn't work either. Nothing loaded when I tried that, the little Active-X icon was in the top left instead of a Red X. That was my first attempt with an applet tag ever though, so it may not have been correct. I think it is obsolete anyways?
function createVCRTarget() {
     createWindow('valid.package.path.VCRLauncher', 'vcr.jar, targetsdk.jar, xercesImpl.jar, cidero-common.jar', 'VCRTarget', '300', '110');
     return true;
function createWindow(classid, jars, title, width, height) {
var agent = navigator.userAgent.toLowerCase();
var newWin = window.open("", title, "width="+width+",height="+height+",scrollbar=no,status=no,statusbar=no,resizable=no");
newWin.document.write("<html>\n");
newWin.document.write(" <head><title>" + title + "</title>\n");
newWin.document.write(" <style type=\"text/css\">body { margin: 0; padding: 0; }</style>\n");
newWin.document.write(" </head>\n<body>\n");
     if (agent.indexOf("msie")==-1) { // not IE
    newWin.document.write('<object classid="java:'+classid+'"');
    newWin.document.write('          codetype="application/java"');
    newWin.document.write('          archive="'+jars+'"');
    newWin.document.write('          width="'+width+'" height="'+height+'">');
    newWin.document.write('</object>');
     } else {
//          newWin.document.write('<applet archive="'+jars+'" code="'+classid+'" height="'+height+'" width="'+width+'">');
          newWin.document.write('<object classid="clsid:CAFEEFAC-0014-0001-0005-ABCDEFFEDCBA"');
//          newWin.document.write('               codebase="http://java.sun.com/products/plugin/autodl/jinstall-1_5_0-windows-i586.cab#Version=5,0,0,0"');
          newWin.document.write('               codebase="http://java.sun.com/update/1.5.0/jinstall-1_5_0_02-windows-i586.cab#Version=5,0,0,0"')
          newWin.document.write('               width="'+width+'" height="'+height+'">');

          newWin.document.write('<param name="type" value="application/x-java-applet;jpi-version=1.5.0" />');
          newWin.document.write('</object>');
newWin.document.write("</body>\n</html>\n");
}Thanks in advance,

I see now that you are forsing IE to use jre version 1.4.1_5 but you provide a codebase
pointing to the 1.5 jre.
It doesn't matter though what you use evan if you use the htmlconverter if the jdk
you'll get wrong values for codebase and/or IE is not able to download the cab
file.
The only way I was able to install the jre through clsid and codebase browsing a
page with IE was to download the cab file with mozilla (if you know the correct url to it).
And then host the cab file yourselve.

Security problem when signed applet dynamically load plugins

Hi!
I have one problem : "security problem when signed applet dynamically load plugins"
This is the scenario:
the main program [app.jar]
. contain applet and shared library (interface & implement of common class)
. it is signed and run normally on browser
. it can draw image loaded from other URL [ex] http://bp1.blogger.com/image.jpg
. the image loader is in the shared library
. dynamically load amazon.jar through URLClassLoader and reflection
the plugin [amazon.jar]
. search amazon product [ex] Harry Potter book
. draw image on applet
. use image loader from shared library, BUT CANNOT LOAD IMAGE
The question: "Why it cannot load image, because the image loader is in the shared library which has been signed and working?" I tried to sign the amazon.jar too, but it did not work.
Your reply would be very helpful. Thank you.

Java security dialog freezes Java & browser when loading signed applet

Hi,
I have a slightly unusual scenario: I have two signed applets. One is developed by me and another one by somebody else. Let's call them Applet A and Applet B.
Here is what hapens:
1)Applet A loads
2)Security dialog for Applet A - "yes, trust this vendor"
3)applet A loads applet B with the following code taken from this sample:
http://www.java-tips.org/java-se-tips/java.applet/have-an-applet-launch-another-applet.html
Class appletClass = Class.forName(appletToLoad);
Applet realApplet = (Applet)appletClass.newInstance();
realApplet.setStub(this);
setLayout( new GridLayout(1,0));
add(realApplet);
realApplet.init();
realApplet.start();
4) Applet B loads
5) Applet B security dialog shows up, but it is gray. From this point on, nothing resonds. The java console is gray, all browser windows are frozen, the dialog is gray and frozen. I can move it around, but it leaves trails.
The only hint that I have is that the last security dialog is a modal dialog, but it seems like it's pushed twice, possibly causing a deadlock?
This is what I see in the trace file:
security: Certificate has been verified with Root CA certificates successfully
security: No timestamping info available
basic: Modality pushed
basic: Modality pushed
Usually a "Modality pushed" is followed by a "Modality Popped".
Does anyone have any idea how I can go about resolving this problem? This is not an issue if I manually import the certificate for Applet B into the java cert. store.
Thanks.

Were you able to figure out the problem? I have the same issue and it is killing me. Please share with me anything you found.

Windows Java 6 Update 22 fails to load signed applet from 1.5 build

Folks,
I built and signed my applet using Java build 1.5.0_21-b01 with a Versign cert. We're finding during testing that the applet simply does not load, but the Java Control Panel lists our cert as expected. We haven't seen this issue with earlier releases of the Java plugin (e.g. before 6u22). Any ideas how to solve?
Thanks

Thanks harmmeijer and mjparme for your responses.
I made some changes to my application and it does not now require the system property information. But now I am getting another exception related to class loader.
I made the changes to the console as suggested by harmmeijer, and here is the stack trace. Also, I am not using any JavaScript explicitly.

OC4J 10.1.3.2 oc4jclient.jar makes permission problems in signed applets

A signed applet on WINDOWS 2000 with JRE 1.5_10 or 1.5_12 plugin in a IE6 browser, which talks to Session beans on a SUN 5.9 OC4J 10.1.3.2 server has no permissions with this library :
example:
at XXX.initContext(BeanFactory.java:69)... // 69: context = new InitialContext(props);
Exception in thread "AWT-EventQueue-2" java.lang.ExceptionInInitializerError
Caused by: java.security.AccessControlException: access denied (java.util.PropertyPermission oracle.j2ee.logging.severe read)
at java.security.AccessControlContext.checkPermission(Unknown Source)...
With the older OC4J 10.1.3 oc4jclient.jar there is no problem !
Therefore I use the older oc4jclient.jar in my applet.

Seems to be a bug. That was the response from Oracle support (Metalink)
Response:
Your issue seems to be related to bug 5594702 - Abstract: EJB30 ENTITY BEAN WITH @ID AND @COLUMN ANNOTATION FAILS TO DEPLOY ON AIX.
There is an issue with the IBM JDK/JRE 1.5's processing of annotations.
Links:
http://www.theserverside.com/discussions/thread.tss?thread_id=37764
http://www-128.ibm.com/developerworks/forums/dw_thread.jsp?forum=367&thread=112543&cat=10
When processing annotations it returns boolean values as false.
Work-around:
Fully specify the @Column annotation's boolean values. If insertable and updatable are set to false (which will happen due to this bug) then TopLink sets the PK
mapping to read-only and the exception seen is expected.
Note: nullable attribute of the @Colmun is not used in the EJB3/JPA preview of 10.1.3.0 If the customer MUST override the default column name then they should use:
@Column(name="column-name", insertable=true, updatable=true)
If they do not wish to override the default column name then simply do not use an @Column annotation.
It can be deleted or commented out in the JDev generated code.
There are two reported annotation processing issues with the AIX JVM. One was fixed in SR1 and the other is fixed
in SR3 (due out Oc 11 - today). Upgrading to these more recent JVM releases may also address this issue.
RECOMMENDED SOLUTIONS:
1. Upgrade the IBM AIX JVM to SR3.
OR
2. Fix all generated @Column annotations as described above

Problem running signed applet in 1.4 plugin

Hello,
We have a signed applet which we're trying to run on clients downloaded over the web. Our client applet is developed for Java 1.4.0. We're signing the applet because it is expected to access local client resources. The client applet runs successfully on some machines and on both IE6 and Netscape 7. We have installed Java Plugin 1.4 on all machines. But on some machines we receive the following exception:
java.security.AccessControlException: access denied (java.util.PropertyPermission java.home read)

in the console, hit "s" to dump system properties on one machine that is working and one that is not, and post the dumps here. If it is a configuration issue, that will likely point to the problem.

Please HELP !!! Signed Applet & Java Media Framework(JMF)

Hi,
I have written a self signed applet that is used for Recording voice running in browser:
The tag that I've given is as follows:
<OBJECT
classid = "clsid:CAFEEFAC-0014-0001-0000-ABCDEFFEDCBA"
id="recordApplet"
codebase = "http://java.sun.com/products/plugin/autodl/jinstall-1_4_1-windows-i586.cab#Version=1,4,1,0"
WIDTH = 268 HEIGHT = 27>
<PARAM NAME = CODE VALUE = "RecWindow">
<PARAM NAME = ARCHIVE VALUE = "jmf.jar,sound.jar,SignedRecWindow.jar">
<PARAM NAME = "soundtrack" VALUE="testFile.mp3">
<PARAM NAME = "type" VALUE = "application/x-java-applet;jpi-version=1.4.1">
<PARAM NAME = "scriptable" VALUE = "true">
<PARAM NAME = "MAYSCRIPT" VALUE = "true">
</OBJECT>
I've also signed jmf.jar as well as sound.jar that come in JMF 2.1 and am including it the archive. These jars are downloaded on client machine.
My code works perfectly BUT only when JMF 2.1 is installed on the clients machine else I get a RunTime Exception stating "no permission to capture from applet".
JMF FAQ states that If a user chooses to allow playing back locally stored media files or saving media files locally, he/she can do so by making use of a policy file. http://java.sun.com/products/java-media/jmf/2.1.1/faq-jmf.html#jmf2-applet-run
My requirement is that once the user has agreed to the signed applet to run then there should be no need to install JMF rather use the jmf.jar that is downloaded on client machine.
Also how can I grant the permission (permission javax.sound.sampled.AudioPermission "record";) to my applet in client computers ?
The client should not be asked to add any files (policy) by itself, all must be transparent for him.
Thanks in advance.
Vipin.

I too have been trying to get Java JMF sound recording to work via webstart. No luck so far.
I even tried playing (security.AllPermissions) with .java.policy file in the user's home directory and even modifying java.policy in the JRE/lib/security directory. No luck there too!
I also added security.AllPermissions to the javaws.policy in the JRE/jawas/javaws.policy file. Still no luck!
Any idea, anyone?

Problem with signed applet

HI All,
I am writing a small applet to draw a line graph by setting the parameters from the html pages .It came up beutifully .There are two problems here .
1)When i try to print the applet it prints only black coloroued rectangle in place of applet(graph) .I read lot of articles only to find out that the applet need to be signed for printed .I tried all ways and means but could not succedd in printing an applet .
2)When i try to access the applet from other computer with out copying it says that applet can not be acceessed due to security failure .It throws exception.
I need your help on how to sign applets to access from other computer and also how to print applet content .
Can any one help me on this
Thanks in advance .

i am not sure of that , but having experience with drawing images ,graphs and the like and with no experience in printing, i can share u my experience.
using setBackground(Color.white) of the applet/panel wouldnot work since i believe it is something that is got to do with the graphics class .U have to draw a full white rectangle as a background before u start drawing lines.
like
g.setColor(color.white);
g.drawfullrect(0,0,width,height); /// draw a white background
g.setColot(Color.black);
g.drawline(0,0);
etc.....
Have fun dude.

Problems with Signed Applets

Hello !
I have an applet program that displays the content of a batch file in the Applet window.
To sign the Applet I have converted the corresponding class file to a jar .
Then using keytool & jarsigner... I had signed it .
I tried to restrict the enuser form editing the contents of that batchfile's contents.
To restrict it I had Created a Policy file with only read permission allowed .
After following the above procedures , when i tried to run my applet, the applet is getting loaded sucessfully with that batch file's content .
And when i try to edit it , I'm able to edit the contents . I don't how this could be possible bcoz i have set the permission only to read it !
Any Ideas Please !
TIA

in the policy file, you restrict the applet to only read files. but if you have already signed it and clicked Yes on the certification screen when loading the applet, the applet gets full permission.
the other thing is that you have a textarea field or something, you must set the textarea to readonly.
if you read in a file's content and display it in a textarea, the user can change the content of the textarea, but if your applet does not write the changes back to the file, the file won't be changed, although the user has changed the textarea content.
perhaps you might post some more info on the code you are using....

Problems with signed Applet for File Download under JRE 1.4 (works with 1.3

Dear all,
i encountered a very strange behaviour with JRE 1.4x. A signed applet used for file download worked on all platforms (Windows NT, 2000 and XP wth/wthout SP...) until I installed JRE 1.4.x (1.4.1 or 1.4.2)
I get an EOFException when downloading binary files (for ASCII it works fine) when trying to readByte() from a DataInputStream. But not immideately, but after x bytes in the while-loop. Security is fine (I know there have been changes to that in jre 1.4, the applet itself can be started an runs with ASCII files for transfer)
Does anyone know, what has changed in jre1.4.
As I said, it works fine under jre 1.3.x
The relevant code is below: byte bt = dis.readByte(); causes the error
try{
// Get URL from Server
URL uFile = new URL(sFilename);
sThisURLFile = uFile.getFile();
Integer inte = new Integer(i);
//open input stream for the file on server
DataInputStream dis = new DataInputStream(new BufferedInputStream
(uFile.openConnection().getInputStream()));
//open output stream for the file on local drive
String sFilenameOnly = sThisURLFile.substring(sThisURLFile.lastIndexOf('/')+1);
int iDotPos = sFilenameOnly.lastIndexOf(".");
String sExt;
if (iDotPos > 0) {
sExt= sFilenameOnly.substring(iDotPos);
} else {
sExt = "";
File fileOut = new File(sDownloadDir + sThisURLFile.substring(sThisURLFile.lastIndexOf('/')+1) );
DataOutputStream dos = new DataOutputStream(new
BufferedOutputStream(new FileOutputStream(fileOut)));
//read one byte from input stream, and write that byte to output stream
long nByte = 0;
int iCnt = 0;
iFilesizeDone ++;
while (nByte < iFilesize){
String sErrPs = new String();
try{
sErrPs = "00";
byte bt = dis.readByte();
sErrPs = "01";
dos.writeByte(bt);
} catch (EOFException ee)
System.err.println("internal EOFException: " + ee.getMessage());
System.out.println("Error Filesize is " nByte " of " iFilesize "---" + sErrPs);
break;
nByte++;
iFilesizeDone ++;
iCnt ++;
if(iCnt >= 10240) {
ShowProgress(nByte, iFilesize, iFilesizeDone, iFilesizeTotal); // repaint does not work during init-procedure
iCnt = 0;
line = "Progress: Total: " + ((iFilesizeDone*100)/iFilesizeTotal) + " perc, " + iFilesizeTotal/1024 +" kbytes" ;
labLine.setText(line);
//dos.flush(); // improves Client performance (Agent-Call!)
dis.close();
dos.close();
}// End try
catch (EOFException ee)
System.err.println("EOFException: " + ee.getMessage()e);
catch (SecurityException se)
System.err.println("SecurityException: " + se.getMessage());
catch (IOException ioe)
System.err.println("IOException: " + ioe.getMessage());

perhaps they've changed something with the file blocking.
btw, you should try to use something like this
DataInputStream dis = new DataInputStream(is);
byte[] buffer=new byte[8192];
int numBytesRead;
while ( dis.available()>0 ) {
numBytesRead = dis.read(buffer);
}

if you are using a thread other than the applets main thread to do something take a look at this:
http://forum.java.sun.com/thread.jspa?threadID=5122942&tstart=0
That includes responding to a UI event because the AWT thread is not the main applet thread.

Problems loading IFS's java class into database

I need store java procedures that allow connecting to ISF and managing files from external applications. The problem is when i try to load the repos.jar that contains the classes needed to work with IFS, using the command loadjava:
loadjava -u user/pwd -v -r repos.jar
the classes are loaded but unresolved due to error: ORA-29534. I follow the steps suggested by metalink's articles but the classes still with INVALID status in the database and i can't use this classes to develop the other classes that i need.
Thanks for any suggest.
FABIAN.

The iFS Java API Classes cannot be used from with the database. This is not supported and will not work....
If you need to access iFS functionaliy from within the database you will need to write an external java process that performs the IFS operations and communicate with that process from PL/SQL running inside the database using Advanced Queuing.

Problem in Signed Applet while communicating with Javascript

Hi,
Im facing a problem with applet. Applet calls JavaScript methods and vice versa. Applet works fine with JRE 5 to JRE 6 up to build no 1.6.0._7 but it fails with build no 1.6.0_10.
The problem description is given below:
After embedding applet in my HTML page using <OBJECT> tag, Ive to check either any problem during applets execution, I want to get the error reason by calling my defined method getErrorReason() in applet that returns the error reason, I call the getErrorReason() against the applets object in JavaScript immediately after embed applet code in my HTML page, a JavaScript errors occurs and my applet fails to perform its execution.
JavaScript error: Object does not support this property.
The error points to the HTML page area where Im calling getErrorReason() against applet object.
The above JavaScript error occurs after the successful completion of Applets init(). Im facing this problem only in JRE 6 build 1.6.0_10-b33.
Please suggest me any solution.
Thanks in advance.

We are using the HttpURLConnection. If I have to go down the stack to the Socket object, well I guess I have to re event the wheel so to speak.
I have tried both Connection: close and Connection: Keep-Alive. Not at the same time :) but in different intrim releases of test applet.
// Here is the current incarnation of how I am trying to connect.
URL url = new URL(sURL);
trace("attempting to connect to URL: " + sURL, DEBUG);
connection = (HttpURLConnection)url.openConnection();
connection.setDoOutput(true);
connection.setDoInput( true );
connection.setRequestMethod("POST");
connection.setUseCaches( false );
connection.setInstanceFollowRedirects( true );
connection.setAllowUserInteraction( false );
connection.setRequestProperty("Pragma", "no-cache");
connection.setRequestProperty("Expires", "-1");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.connect();
// Now I write our form POST data and flush and close the output stream.
BufferedOutputStream bos = new BufferedOutputStream(connection.getOutputStream());
bos.write(sForm.getBytes());
bos.flush();
bos.close();
// Get the input and read
bis = new BufferedInputStream(connection.getInputStream());
trace( "reading input stream for action: " + sAction );
byte[] responseBuffer = new byte[4096];
int bytesRead = 0;
while( (bytesRead = bis.read( responseBuffer, 0, responseBuffer.length )) != -1 )
sbResponse.append( new String( responseBuffer, 0, bytesRead ));
totalBytesRead += bytesRead;
catch (Throwable e)
e.printStackTrace();
try
m_connections.remove( sAction );
connection.disconnect();
catch ( Throwable t ) {}
finally
if ( bis != null )
try
bis.close();
catch( Throwable t ) {}
With the above code in place what I am now seeing, as opposed to a premature EOF exception, is blocking behavior on the read.
