Is this an OpenSSL or httpd or JAVA problem ???
Hi All.
Problem: Netscape 6.2 will not "redirect" from http://my.first.dom to https://my.secure.dom
Objective : from first web-site, create a link to a secure web-site in index.html using an anchor e.g. ClickMe
Set up : Apache2 httpd + mod_ssl + Tomcat + Oracle. Tomcat holds java servlets. Apache server has applets communication with servlets.
What works : Everything works just fine using W98+MSIE5 or Linux+Mozilla.
What doesn't work : When I key in URL my.first.dom in Netscape 6.2, it takes me to the site. When I click on the link to my.secure.dom, it presents again my.first.dom, as if it couldn't resolve the link-URL and use the former as default.
Error messages : in error log, only a "seemingly" unrelated entry which says SSLSessionCache not configured (this is true, I don't really want to cache anything). At some point, JAVA console prints this message :
General Exception
java.lang.SecurityException: illegal CRL redirect
I cannot even begin to duplicate these Netscape6 problems in Mozilla or MSIE5.
What's in httpd.conf :(httpd.conf)
Listen 192.168.100.1:80
Listen 443
NameVirtualHost 192.168.100.1
<VirtualHost 192.168.100.1:80>
ServerName my.first dom
</VirtualHost>
# I added following redirect in the hope Netscape6 would work - didn't!
<VirtualHost 192.168.100.1:80>
Server my.secure.dom
Redirect /index.html https://my.secure.dom/index.html
</VirtualHost>
# as far as MSIE5 and Mozilla are concerned, they only need the following lines to work properly
<VirtualHost>
ServerName my.secure.dom
<IfModule mod_ssl.c> ... blablabla </IfModule>
<VirtualHost>
Dude - if it works for two browsers out of three, then I'd stop looking at the httpd side of the equation. See if you can find a Netscape-6-bugs board and ask what's wrong with NS6.

How to run a openssl command from a java program
Hi All
Please suggest on how to run a openssl command from a java program.
I am using this
Runtime runtime = Runtime.getRuntime();
runtime.exec("openssl pkcs8 -inform der -nocrypt test.der result.pem");
This is suppose to take test.der as input and create result.pem.
There are no errors but the file result.pem isnt created.
Thanks in AdvanceFirst off is that openssl command correct? Should it be this instead:
openssl pkcs8 -inform der -nocrypt -in test.der -out result.pem
Try out your openssl command within a command prompt so that you know that it works ok. I think the command line you specified waits on stdin (well it does for me).
After that.....
runtime.exec creates a Process object. If you do this:
Process openssl = runtime.exec("....")
then you can examine the return code from openssl to see the exit code - for instance if the input file does not exist then exit = 1. You can test for this with Java
Alternatively you could get the stderr from the process and look inside it - if it is 0 length then all is good, if it has some text in there then it has likely failed. You could then throw an exception and include the stderr output in the exception messgae. You may need to experiment with this, runnig it first when openssl is happy then running it again when openssl is upset.

HELP Needed with this error: Exception in thread "main" java.lang.NoClass
Folks,
I am having a problem connecting to my MSDE SQL 2000 DB on a WindowsXP pro. environment. I am learning Java and writing a small test prgm to connect the the database. The code compiles ok, but when I try to execute it i keep getting this error:
"Exception in thread "main" java.lang.NoClassDefFoundError: Test1"
I am using the Microsoft jdbc driver and my CLASSPATH is setup correctly, I've also noticed that several people have complained about this error, but have not seen any solutions....can someone help ?
Here is the one of the test programs that I am using:
import java.sql.*;
* Microsoft SQL Server JDBC test program
public class Test1 {
public Test1() throws Exception {
// Get connection
DriverManager.registerDriver(new
com.microsoft.jdbc.sqlserver.SQLServerDriver());
Connection connection = DriverManager.getConnection(
"jdbc:microsoft:sqlserver://LAPTOP01:1433","sa","sqladmin");
if (connection != null) {
System.out.println();
System.out.println("Successfully connected");
System.out.println();
// Meta data
DatabaseMetaData meta = connection.getMetaData();
System.out.println("\nDriver Information");
System.out.println("Driver Name: "
+ meta.getDriverName());
System.out.println("Driver Version: "
+ meta.getDriverVersion());
System.out.println("\nDatabase Information ");
System.out.println("Database Name: "
+ meta.getDatabaseProductName());
System.out.println("Database Version: "+
meta.getDatabaseProductVersion());
} // Test
public static void main (String args[]) throws Exception {
Test1 test = new Test1();I want to say that there was nothing wrong
with my classpath config., I am still not sure why
that didn't work, there is what I did to resolved
this issue.You can say that all you like but if you are getting NoClassDefFound errors, that's because the class associated with the error is not in your classpath.
(For future reference: you will find it easier to solve problems if you assume that the problem is your fault, instead of trying to blame something else. It almost always is your fault -- at least that's been my experience.)
1. I had to set my DB connection protocol to TCP/IP
(this was not the default), this was done by running
the
file "svrnetcn.exe" and then in the SQL Server Network
Utility window, enable TCP/IP and set the port to
1433.Irrelevant to the classpath problem.
2. I then copied all three of the Microsoft JDBC
driver files to the ..\jre\lib\ext dir of my jdk
installed dir.The classpath always includes all jar files in this directory. That's why doing that fixed your problem. My bet is that you didn't have the jar file containing the driver in your classpath before, you just had the directory containing that jar file.
3. Updated my OS path to located these files
and....BINGO! (that simple)Unnecessary for solving classpath problems.
4. Took a crash course on JDBC & basic Java and now I
have created my database, all tables, scripts,
stored procedures and can read/write and do all kinds
of neat stuff.All's well that ends well. After a few months you'll wonder what all the fuss was about. -

JTable displays string in wrong order : my code problem or Java problem ?
I have the following code that displays data in a JTable, most of the time it works fine, but I've realized when I have a cell with values like : "Snowboarding"+"[123456789]"
It would display it as : [Snowboarding[123456789
For a string like : "Chasing toddlers"+"<123456789>"
It would display it as : <Chasing toddlers<123456789
It not only moved the last bracket to the front, but also changed its direction from "]" to "[" and from ">" to "<"
Is there anything wrong with my code ? Or is this a Java problem ?

* TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
* or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
* model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
* have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
* with the rows in a different order.
* <p/>
* TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
* are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
* If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
* rows the next time a value is requested.
* <p/>
* When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
* header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
* that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound sort.

* TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
* or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
* model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
* have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
* with the rows in a different order.
* <p/>
* TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
* are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
* If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
* rows the next time a value is requested.
* <p/>
* When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
* header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
* that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound sort.
* </ul>
* <p/>
* This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

Error Code 16 on Mac with Newly-Installed Yosemite (a Java problem?)
Like many out there I am unable to use CS6 applications at all after an OS update to Yosemite (in my case from 10.8.5, on my 2012 iMac). I get an Error 16 message, and a Java problem error message.
I've read many posts about fixing this issue, including the Adobe gospel very specific to this problem—about changing the permissions in a couple of folders—, which I found here: https://helpx.adobe.com/x-productkb/policy-pricing/configuration-error-cs5.html I did exactly as directed and saw no change in the problem.
I also read that the Java version necessary for CS6 products to run on Yosemite is a boondoggle in itself. Java 6 is apparently necessary for CS6 products to run, but that version is insecure, and besides, it's old. Java 8 Build 31 is the current and safe version but it apparently is incompatible with none but the most recently-updated Adobe products. Several posts on Adobe's support pages suggest a hacky fix for this Java issue, which involves downloading and installing the latest Java version from Oracle, and then creating specifically-named empty folders on one's hard drive within a couple of obscure System/Library/Java folders:
http://oliverdowling.com.au/2014/03/28/java-se-8-on-mac-os-x/
https://forums.adobe.com/message/7193884
I did this too, and again saw no change in the problem.
Re-installing my CS6 suite has not worked, either. I receive the same error code message when starting up any of the applications. At this point I've been forced to go back to my previous operating system, since I am heavily reliant on CS6 to do my work each day.
I understand that many people are having this trouble after updating to Yosemite, and more than a few posts on these forums indicate this is true even for people like me who've followed Adobe's purported fix that I linked above. Has anyone in userland or at Adobe found anything lately that could help here?uninstall cs6 and clean (Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6).
update your os, Java for OS X 2014-001
then install cs6. -
Installing 9.2.0.4.0 on EL4 - Can't start netca, JAVA problem!!!!
Dear all,
Please help with my Java problem. Thanks in advance.
After successfully installed Oracle 9.2.0.4.0 on EL4, I tried to start netca but I received this error message:
[oracle@localhost bin]$ ./netca: line 138: /u01/app/oracle/product/9.2.0.4.0/JRE/bin/jre: No such file or directory
The JRE link at $ORACLE_HOME is as follows:

.bash_profile as follows:

CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlib; export CLASSPATH
LD_ASSUME_KERNEL=2.6.9; export LD_ASSUME_KERNEL
What do you guys think my problem is?I managed to solve this one. For more information you can search the forum with much earlier dates, as far as 2002. I'm very outdated.
In case you need the solution:
I tried using java 1.3.1 provided together with the Oracle9iR2 installation Disks instead of 1.1.8.
1. Delete the JRE link in $ORACLE_HOME
2. Relink it to 1.3.1 directory
3. create a jre symbolic link in the bin directory to the .java_wrapper
4. create another jre symbolic link in the i386/nativethreads directory to the java file
Good luck -
java problem
Well my latest build of java stopped working after Tuesday's Microsoft updates. I cant believe those updates are connected as to why this java build 5 should have stop working like that as the Standard Edition, v 1.4.2_08 (J2SE)works fine
Any ideas anyone as to why this should have happened
thanks
--Sending this back to the top.. I have seen on a couple other forums where people were having this problem, but no answers yet.

Please help me with two Java problems
Hello,
I have 2 Java problems to work on and wondered if someone can help please?
1. I've created an array, but I have to now create a text file and write a program to read the array from the file. I have no idea where to start the program!
2.public class SumExample1 {
/* To determine if a number lies between 1 and 1000
* @param args the command line arguments
public static void main(String[] args) {
int num;
System.out.print("Enter a number: ");
num = TextIO.getInt();
if ((num >=1) && (num<=1000))
System.out.println("OK");
else
System.out.println ("Not OK");
Ive used a GUI to create some fields and buttons to press. How can I make it perform this little program?
Many thanks,
KI recommend you read the tutorials on basic (file) IO and Swing (and Event Listeners if you want to make your GUI alive). Perhaps have a look at the Scanner class and BufferedInputStream. That should give you enough to start and write the program yourself. Try working in the command prompt first, should be easier, then once the logic works wrap it in a Swing GUI.
You can find the tutorials here:
http://download.oracle.com/javase/tutorial/
Swing:
http://download.oracle.com/javase/tutorial/uiswing/index.html
Basic IO:

Hope this helps.

Getting the error " [java] Problem invoking WLST - java.lang.RuntimeException: Could not find the OffLine WLST class " while building the O2A 2.1.0 PIP. I am using the Design Studio 4.3.2 for building the O2A 2.1.0 PIP. Please let me know how to resolve this issue. Here I am enclosing the log file .
We have basically the same issue when we try to create the interpreter using the embedded method..
I was able to use the interpreter embedded in a java client as long as the weblogic jars were located in a weblogic install if I tried to use them from a maven repository no luck at all...
All of this worked easily in 9.2 now in 10.3 it seems more error prone and less documented.
I have seen close to a 100 posts on issues related to this so is there a document which outlines specifics....
We / I have used weblogic now for almost 10 years and moving from 8.1 to 9.2 was painful and we expected the move from 9.2 to 10.3 not to be soo bad but its proving to be as painful if not more painful than moving to 9.2. We seem to spend a good bit of our time working around issues in the next new release that were not in the previous one..
Any help would be appreciated I think we will open a support case but even that is more painful...
Any help would be greatly appreciated..
PS: We confirmed that all jars in the startweblogic classpath were in the startup. The server we have the embedded wlst instance is a managed server and we are using the component in a war... Are there any restrictions which we are unaware of.
Error we get is
1 [ERROR] com.tfn.autex.order.weblogic.QueueMaintenanceUtility.addQueue():217 Error Adding Queue wowsers JNDI Name wowsers Exception: Invocation Target exception while getting the WLSTOffLineScript path -

Java problem after update 2012-006
Hi,
Today was update 2012-006 concerning java. It deinstalls java 6 from your mac. If you want java, you get it from java.com. This is a java 7 version.
but help: I want to go back!
there are some web-apps that do not work with this new java-version. Downgrading is not possible, becauase java 6 is only available through mac update itself. And if I want to install this again, it says that a newer version is already installed.
can anybody hellp me out?Today was update 2012-006 concerning java. It deinstalls java 6 from your mac.
That is not actually correct, according to Apple's documentation of Java for OS X 2012-006:
https://support.apple.com/kb/HT5549
It should update Java to 1.6.0_37, which is still Java 6. (Java 7 is 1.7.x.) However, Apple has changed the way Java works. The system now disabled Java by default, and if you turn Java back on, the system will disable it again if you don't use it for a certain period of time. It's also possible that the system will disable Java every time there's an update. (I'm not sure about that, as I don't have Java installed myself, for security reasons.)
For more information about this, including how to re-enable Java, see Using Java in Mac OS X. You should note, though, that enabling Java in your web browser has become a very risky proposition... Java has more holes in it than Swiss cheese! -
Is the Java problem that you brought to my attention sorted yet, as I keep getting prompts to download latest Java update.

Hi,
I'm having a problem with the newest updates to Safari. This problem did not occur until late december when I installed several updates via Software Update.
Problem:
I use a photo uploader on a website from my company (unfortunately I can't give out the URL, as it is protected). But it is similar to many other photo uploader sites - load a Java applet, drag images files into a Java window, the files are added to a upload list and then uploaded.
Now, if I drag 10 items into the window, only one or two will be added to the list. If I drag them in one at a time, all the images will be added. Previously it was possible to drag as many as one wanted in.
Now the really irritating part : During the upload, the Java uploader completely hijacks Safari. The window the uploader allways stays active on top. If I open a new tab or window the uploader window will reappear on top and dominate the action. The only way to get anything done while I am uploading photos is to open another browser like Firefox. Safari is completely occupied with the Java program.
Computer: MBP 2.16 GHz, 2GB RAM, OSX 10.4.11
Safari 3.0.4
Java 5.0 (not sure of the revision, but it is the most recent)
Any help would be greatly appreciated.I had similar Java problems with Safari and Firefox. I downloaded Navigator and now can run any Java app I need. One thing that may or may not have had any impact: when installing Nav, it asked if I wanted to import settings from Safari or Firefox. I chose not to import any settings. Works perfectly.
