When our applet loads on our HTTPS website, the JRE is rejecting the website certificate, saying it does not recognize the Certificate Authority (which is Thawte). Internet Explorer is happy with the certificate.
With tracing turned on, I can verify the JRE is checking the certificate authorities of IE, but for some reason rejects all of them. The trace shows this:
security: Certificate has failed the verification with the Internet Explorer ROOT certificates security: Invalid certificate from HTTPS server
We've tested several versions of JRE 7 and the latest version of JRE 8. All of them reject the certificate authority. This happens on various versions of Windows and Internet Explorer.
Please note that I'm not referring to the certificate used to sign the applet. The JRE is happy with that certificate.
I have tried running the java application without adding the site to site list in java security tab. But I get a sand box message as APPLICATION BLOCKED BY SECURITY SETTINGS. How to run the java application without adding the site to site list in java security tab.
There's a site that uses DBsign UWS to validate personal certificates on a smart card. I wound up breaking that functionality by moving the default Java truststore so I could create a new one with just root/intermediate CAs that I trust (I have no desire to allow apps signed in China, Russia, Turkey, and countries spelled with heiroglyphs). Now, my browser believes the UWS is self-signed and rfuses to run it. I need to find the certificate used to sign that app to see which cert(s) signed it, so I can add them back to the truststore. How can I find that?
As the JRE environments and usage of applets has become more and more secure in through the evolution of enhancements to the JRE we have noticed a performance degradation in usage of these applets and launching of them.
As our customers are in the business to business environment they utilize our applets that are delivered from the server to the client. We are looking at ways to reduce the time to validate that the certificates are still valid. we are looking for ways to provide a means for our customers to validate against a CRL on our server or to cache the the checks against the OCSP so that not each and every client accessing our server needs to go out to the third party sites to get the checks completed.
Is there a means to store this information on our server and have the JRE validate against that system rather than the normal OSCP...
I have a problem with several java applications. When I start them Java wants to connect to the certificate authority, to check if the certificate is still valid and not on a blacklist.
The problem is: my whole internet is behind a password protected proxy. If I open my browser i get a windows with username and password. I enter it and internet in the browser works. But for Java it isn't working, because I see no point, where I can enter the password and username for the proxy. I can enter the proxy ip and port in the java settings, but not the password and username. So I get a error screen from java, telling me, that java could not connect. I can disable the check in the java settings, but I don't wont that.
Is there a way to tell java, that java uses my proxy with my password and username? I already googled this problem and found nothing except tutorials for connecting with proxy in the java code. But these applications are not from me, I can't change the code ...
The error I get is as follows...When the page is loaded I get the following error: java.lang.SecurityException: class "com.myPackage. test.client. TaskApplet" does not match trust level of other classes in the same package
Write a piece of code that would change something in the one of the buttons created using the loop? I have spent few hours reading about the arrays, different methods and can't think or apply a working solution.
I am doing an multi user chat application, i don't know how to identify the particular pair of user (both end chatting user) among users. and want to send message separately.., which steps i have to fallow, HasMap(); or what is the procedure to achieve my target.
This is my server side program,
Java Code:
import java.util.*; import java.net.*; import java.io.*; public class ChatServer { Vector<String> users = new Vector<String>(); Vector<HandleClient> clients = new Vector<HandleClient>(); public void process() throws Exception { ServerSocket server = new ServerSocket(1234);
Im running an eclipse application in my machine. I have two queries
1. I would like to know how to check the default heap size that the jvm is using to run the application.Im using a windows machine to run the java application. I tried to check the default heap size by the following way ControlPanel--->Programs--->JavaSetting--> JavaTab -->View Button ---> JavaRuntimeEnvironment settings window ---> Userstab --> Value under RuntimeParameters
But in my system, there is no runtime parameters defined. Is there a command that I can execute via command prompt to check the default heap size in my machine.
2. How to increase the heap size parameter and run the eclipse plugin application from command prompt. For eg: To increase the heap size and execute the jar file we use the below command java -Xms64m -jar MyApp.jar. I would like to know how to set heap parameters and execute my java application which is an exe file. I tried to execute use the below command, but the command prompt doesnot recognise the command
I have a problem with my code i try to identify users by password and username but I cannot recognize only the last row in my table in database what can i do ....
I am having difficulty with a sorting routine. I believe that the concept is valid (although not necessarily the most efficient), but I keep running into a problem. I am trying to use the compareTo function to identify the relationship between two values in an array, but it seems to have an issue with it being a comparison of two float values.
Java Code:
for (int x = 0; x < 430; x++) { for (int y = 0; y < 430; y++) { if (dataArray[y].compareTo(dataArray[y + 1]) > 0); { tempOpen = dataArray[y];
[Code] ....
It gives the compile error as follows:
File: C:UsersBradDownloadsAssignment 3Calculations.java [line: 157] Error: Cannot invoke compareTo(float[]) on the array type float[]
So I just processed this rectangular array and made myself a table. I want to put a label for each column to identify what the values are. My attempt at this failed miserably, because it looks horrible. Here is the necessary code.
If you are to compile this yourself, you would see the horrible output at the end. I would like to know how to properly align each label with its corresponding column.
I have a java file 'Arithmetic.java', in which i have 2 overridden method.Now i wanted to read this file and i need to print all the method signature lines,if i found same(overridden method)signature then i have to print "overridden method found". once i find the overridden method i have to suffix the method name as methodName_overridden1, methodName_overridden2 and so on...
package com.abcd.arithmetic; public class AllArithmatic { public Integer add(int x,int y,int z) { return (x+y-z); } public Float substract(float x, float y)
[code]....
till now i am able to read the lines, able to read the method names as well. but while putting the entire method signatures into an string array and the suffixing part , i am not able to proceed. The condition i have put to find out oerridden method is nnot working.i am stucked in comparing the duplicate method
//Finds Method Name, Method Return Type if(indexOfMethod >-1 && indexOfOpenBrace >-1){ int uniqueWordsInFile=0; //Method signature Start //System.out.println("method line="+line.trim()); List<String> methodList = new ArrayList<String>(); methodList.add(line.trim());
convert or move standalone java thread application into Tomcat server container for accessing its JNDI services? Also is it possible to schedule this thread application in Tomcat server? is it possible to keep this app in tomcat as web application and schedule in window's scheduler.
I am new to work on JNLP program. I have created a SWING program, JNLP file when i deploy the ear file i am getting 404 error. Please find the steps in details.
1.Created a dynamic web project JWStartProject in eclipse
2.Create a HelloWorld.java class under default package.
import javax.swing.*; public class HelloWorld extends JFrame { private static final long serialVersionUID = 4968624166243565348L; private JLabel label = new JLabel("Hello Java Web START!"); public HelloWorld() { super("Jave Web Start Example"); this.setSize(350, 200); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE ); this.setLayout(null);
[Code] ....
Now I exported this project as JWStartProject.war contains following code.
Created Server in Websphere Admin console
Deployed this war file under the server and started.
I have added MIME types also.
I am unable to launch the application. I am getting 404 errors. May I know where I went wrong?
this is what I clobbered together for the O'Reilly Java 2 Course, final assignment. There may well be several issues still with this code, my main grief at the moment is: The mouseReleased does not react (it did in the assignment I lifted it from and made only minor changes). No matter where I click on the grid, nothing happens.
I do not think this is possible, but I'd like to confirm. If I have an HTML page that has an embedded Java applet, and that applet in turn renders an HTML document (within the applet window), is the HTML *within* the applet part of / accessible through the DOM for the parent page?
We are using an applet in our web application. The applet of our application is dependent on bouncycastle jar,bcprov-jdk15.jar and few other jar's whose size comes around 4 mb. When using the appliaction on jre7, the applet is taking too long time to load than usual time. Is there any way to place these jar's in client machine? Will it improve the performance? Is there any other way to reduce the loading time of applet apart from placing jars in client machine?
I have a simple applet that doesn't stray outside the sandbox. It used to work fine before Java 7 but now it craps out with security warnings. It does nothing but play a game, it doesn't even save the state of the game. This is the applet, it's a very simple chess program.
The warnings and popups I'm getting are: activate javaTM platform SE 7U?allow now?activation blocked by security settings - I never changed any security settings and as I said, this applet stays firmly in the sandbox so I can't see what the issue is.Viewing the java error window I see
Java Plug-in 10.51.2.13 Using JRE version 1.7.0_51-b13 Java HotSpot(TM) Client VM User home directory = C:UsersMike ---------------------------------------------------- c: clear console window f: finalize objects on finalization queue g: garbage collect h: display this help message l: dump classloader list m: print memory usage o: trigger logging
[code]....
why it shows the C:UsersMike directory in the above listing, there is no access to files etc.The applet plays fine if I run it in appletviewer.What do I need to do to make this simply work in anyone's browser? I have a similar problem with a (rather funky) Connect 4 program I wrote. It worked fine for years and then just stopped with the Java 7.
I'm developing an Applet that print a bar code using Jpos API. I need some jars and two configuration file. I've added jars to the classpath and configuration files in src directory. In Eclipse everything works fine.
DefaultProperties prop = new DefaultProperties(); prop.loadJposProperties(); SimpleXmlRegPopulator xmlReg = new SimpleXmlRegPopulator(); xmlReg.load(wincor.jpos17.THxxx.xml");
Everything works fine in Eclispe but I can't find property files when i call the applet from a web page. So I've checked the JavaPos sources and I've paste the loadJposProperties() and xmlReg.load("wincor.jpos17.THxxx.xml") content in my source code:
InputStream isD = prop.getClass().getClassLoader().getResourceAsStream(prop.JPOS_PROPERTIES_FILENAME); // (1) content of loadProperties if (isD != null){ System.out.println("jpos/res/jpos.properties found");
[Code] ...
The same method is used to found wincor.jpos17.THxxx.xml. So when I call applet form the browser I get INPUT STREAM FROM PROPERTIES OK!! from (1) and jpos/res/jpos.properties not found from (2).
So getClass().getClassLoader().getResourceAsStream works if i write it directly in my code, but doesn't work if i call a jar method.
I am currently trying to update a few java applets for a website. As of right now, the applets are automatically blocked on all computers when they are accessed because the newest updates for Java have caused them to be blocked. I have determined that the solution to this is to resign the .jar files that are used to run the application with a new certificate.
I requested and received a certificate (in pkcs 12 format, a .p12 file), imported it into the computer, and used it to sign the .jar files. However, I have been getting an error after signing the .jar files stating that the full certificate chain of the code signing certificate is not valid.
I tried to check the path of the certificate using a method he recommended (using OpenSSL) but didn't really find anything of use.
