Bypassing proxy/firewall with Applet URLConnection?

I am trying to download images from an image server to an Applet. Currently I am using URLConnection to connect to server and download the image to a byte array.
The problem arises when I try to download the images through a proxy/firewall. The applet doesnt seem to connect to the server using URLConnection, however it works fine over a standard modem connection!
Running the code as an application, instead of an applet with the following parameters to use the proxy :
Properties systemProperties = System.getProperties();
systemProperties.put("proxySet","true");
systemProperties.put("proxyHost",host);
systemProperties.put("proxyPort",proxyport);
System.setProperties(systemProperties);
This works perfectly, and the images are downloaded.
The problem is that I need to run it as an applet and not as an application. I was under the impression that the browser settings for proxy and port will automatically be sent to the applet and I dont have to set it manually.
Please let me know if anyone has any solutions. Thanking you in anticipation!

On IE, you can to limit the addresses that will go to access the proxy server.
On Tools Menu select the "Internet Options" Then "Connections" then "Lan Configurations" Then "Advanced" then "Exceptions" now input the addresses that don�t will utilize the proxy/firewall.
Excuse-me by my English.

Bypassing Firewall/Proxy Settings with Dreamweaver CS3

Hello,
The company that I work for has given us Dreamweaver CS3 and
it's great, however we have a problem with the companies firewall
blocking Dreamweaver from seeing external images when in "Design"
view. I have search throughout Google for a solution and have yet
to find one. I come here in the hopes that someone can help. Our IT
department has told me that the firewall solution they use does not
allow rule sets per application, so they cannot just say "allow
this program to use the web". This leaves me in a tough spot, but
they said in Dreamweaver CS3 has a way to setup a proxy and allow
it to bypass our firewall that would make this quick and easy. Does
DW have something like this, and if so then please point me in the
right direction!
I appreciate all assistance.
Regards,
John

Maybe not per application but certainly by PC or IP adress.
Can they put
your IP adress in a rule less agressif.

Applet bypassing proxy

I have an applet behind proxy/firewall. My browser settings uses auto config and specifies the .pac file. But plug-in seems to always bypass the proxy even though the java console has the checkbox "Use browser settings" checked. Any extra config needed? I am using 1,4,2_08

Have you tried specifying your .pac file in "Automatic Proxy Configuration URL" field at the bottom of the "Proxy" tab in Java Control Panel? You'll have to uncheck "Use Browser Settings" checkbox first.

Bypass proxy for FQDN with private ip addresses

We have Windows 7 with IE 11
We need this IE behavior:
"to all FQDN names that resolves to local (private) ip addresses - do not use proxy."
how can we implement this?
("Bypass Proxy Server for Local Addresses" Option don't work as needed)

Hi,
Please take a check to see if the following KB article could help here:
Internet Explorer Uses Proxy Server for Local IP Address Even if the "Bypass Proxy Server for Local Addresses" Option Is Turned On
The cause: By default, only host names are checked when the Bypass proxy server for local addresses option is turned on.
The resolution here is :
To bypass a range of IP addresses or a specific domain name, specify the addresses in the proxy exception list:
In Internet Explorer, on the Tools menu, click Internet Options.
On the Connections tab, click LAN Settings.
Click Advanced, and type the appropriate information in the
Exceptions area.
Hope this may help

How to know whether bypass proxy for local address is enabled in browser

Can anyone help me in finding out whether the check box "bypass proxy server for local address" in Internet explorer (Tools->Internet options->Connections->LAN Settings) is enabled from java plug in.
In my applet application if that checkbox is enabled then i have to throw a message saying that the checkbox is enabled.
Thanks in Advance

Vijay

We have been in discussions with Microsoft over the last few days on this issue - which is seen with Outlook 2007 versions onwards. Extract from resolution communication from Microsoft:
The issue you have raised is known as it has been reported and when you have a proxy set in Internet Explorer and “Bypass proxy settings for local addresses”, Outlook will attempt to connect to Office 365 directly – like the bypass rule would apply.
Because the direct connection is blocked in the Firewall, Outlook needs to have the connections going in Timeout before attempting to connect using the Proxy.
Your network trace proves the issue.
Microsoft have scheduled a fix for Outlook 2010 in February 2014 cumulative update. A fix for Outlook 2013 will also follow, but Outlook 2007 will not be addressed because it is in Extended Support.
There are two possible workarounds for this behaviour:
First, and I wouldn’t recommend it, is to allow Direct traffic through the Firewall to Office 365.
The advantage of this approach is that it will be done centralized and it will impact everyone immediately.
Information about the O365 IP addresses
There are two downsides to this behaviour:
1. First you need to maintain the Firewall exceptions as IP from O365 server can change without notice
2. Second, winhttp traffic may go through both proxy and direct and this can cause unforeseen behaviour.
The second approach is to use a proxy pac instead of manually setting in the proxy and the exceptions.
The advantage is that you will have centralized method to control how winhttp traffic goes and the issue will not be experienced anymore.
If a single pac does not be fit, you can configure proxy pac files for each site requirements and use an IIS server to store it.

JVM issue with applet - Duplicate Key in Parameter Table - Bad Magic Number

Hey, I have Googled this one to death and have seen a few vague references to this problem, but nothing I can relate back as solution.
I wonder if I need to tell the customer to reinstall the OS and, ultimately, the JRE. I'm just looking for a little guidance on what any of you may think. Am I missing a setting or something?
The user is trying to download an applet with IE with 1.3.1_16 and Firefox 1.07 with the Java Embeded Plug-in.
Even though JRE 1.3.1_16, 1.4.2_09 and 1.5 are all installed and Firefox has the JEP also installed, Firefox still wants to use 1.3.1_16 as does IE. I'm guessing that the JEP didn't work.
They can't use Safari which does seem to be using 1.4.2_09 because their RSA ID won't authenticate through it.
On my machine, when I run with the same OS,browsers, and Java 2 plug-ins, I can successfully load the applet.
This is the error that the user gets in the java console is:
Duplicate key in parameter table: code using the htmlAttribute.
first: com.ibm.eNetwork.HOD.HostOnDemand
second: com.ibm.eNetwork.HOD.HostOnDemand.class
java.lang.ClassFormatError: com/ibm/eNetwork/HOD/HostOnDemand (Bad magic number) at java.lang.ClassLoader.defineClass0(NativeMethod)
at java.lang.ClassLoader.defineClass(ClassLoader.java:488)...
Would you reinstall the OS and Java? or look at another setting? or look at the JEP installation again?
Thank you.

Without reading the full post (sorry for that) my guess is that the applet needed to be fetched through a
proxy, the proxy corrupts the applet because it's signed (finjan is one that does that).
The reason why a proxy would do so is because the default settings of sun jre will ask the user the
"do you trust" question to the user which could result in the user loading an applet that is allowed to do
anything the programmer wants (4us, spyware, nasty stuff).
Try to do the following:
1. create a html file locally with the following content:
rightclick and save target as
2. open the page, right click the link and save the file
3. apen the file with an unzip programm (winzip) and check if the content has changed.
4. If the content has changed than the proxy might have done this, contact the system administrator
It might allso have been done by a firewall installed locally.

Bypass Proxy for Local Addresses - Office 365 connection/ Outlook 2010

This is a strange one. Connectivity to Office 365 within our netwotk works fine although very slow for outlook 2010 client to initially connect. Once connected, it works ok. I have done a netwotk trace using netmon to see if i can identify
the reason for the slow startup (2 mins minumum for profile to load and for outlook to connect to exchange). The trace tell me that my local pc tries to make a direct connection to the office365 external IPs first, then tries the TMG proxy. Once it hits the
proxy, it kicks into life and works.
So it looks to me like it thinks the external IP address of office 365 is an internal address and spends it time trying all the ip addresses until it trys the proxy. At this point, the
Bypass Proxy Server for Local Addresses is ticked.
As soon as i untick this box, all traffic heads directly to the proxy and of course it connects like lighting. The exchange settings proxy is set in outlook for "on fast networks, connect using HTTP first, then connect using TCP/IP" (tick
is on) and the same for slow networks.
I cant for the life of me work out why it tries to connect directly to the external IPs first and not connect via TMG until i untick the
Bypass Proxy Server for Local Addresses
Would love any ideas that may assist.

Proxy server with user/password

Hello,
I'm trying to use Jdev behind a firewall with ip + port + USERNAME + PASSWORD
How configure Jdev to work with this firewall
Option Preference Proxy does not give the choice of login/password preference...
Is there a config file where I can set my preferences?
Thank you

It is possible to configure the proxy host, port and exclude list via system properties, but not the authentication information.
To implement proxy authentication, you must add code to each place in your application where you use a URLConnection. In response to a status 407 response (Proxy Authentication Required), you must resend the request with a Proxy-Authorization header.
This is not trivial, since the content of the Proxy-Authorization header is dependent on the authentication scheme being used by the proxy. There are a number of different authentication schemes used by popular proxy servers. For instance, many people use a Microsoft proxy server which uses a proprietary authentication encoding mechanism known as NTLM to support authentication using Windows domain username / password combinations.
Anyway, this is why it's pretty hard to support username/password proxy authentication in Java applications, and hence why it's frequently not supported in apps like JDeveloper. Support for this is logged as an enhancement request, and we will eventually implement a solution.
Thanks,
Brian

Strange info in "Bypass Proxy Settings for These Hosts and Domains"

For my Mac Mini my Network IP Address always has a self-assigned 169.254 number that I cannot change. Strangely, this same IP number is similar to info that is in the Proxies section (of Network Settings) under "Bypass Proxy Settings for These Hosts and Domains".
No matter what I do, this info (*,local, 169.254/16) appears in my Network Settings in the Proxies section under "Bypass Proxy Settings for These Hosts and Domains". (I tried removing the info and it would cause the "Configure Proxies" selection to default to "Always Use PAC File". Had to go back and retrash all the plist files to have Proxies go back to "Configure Proxies-Manually". Still, the info (*,local, 169.254/16) continues to appear in the "Bypass Proxy Settings for These Hosts and Domains" section and my IP address is always a 169.254 number.)
Comcast cable modem via direct hardwired Ethernet works fine with my other computer, so not the modem. Also, other computer does not have any info in the "Bypass Proxy Settings for These Hosts and Domains" section.
Installed a fresh copy of OS X 11.5 on a new hard drive. Still the same problem.
I posted this issue before but only got one responder and the problem still exists. Any clues? Somebody must know about this stuff. Help please.
Thanks

When your Mac wakes up, it does not yet have an IP Addresss. It wants to send a request to a Router for an apprpriste IP address to use now. But it needs to have an IP address (like a return address) to receive any messages. So, ... wait for it,
... it (your Mac) makes one up. There are rules that ensure it is a random address, but they always start with 169.254. It is on the same subnet with any low-order 16 bits This is the "self-assigned" range of IP Addresses. This address is only good for talking on a local network segment, for things like asking for a valid IP Address from a DHCP-enabled Router.
In most cases, on most networks, the 169.254 self-assigned IP Address is replaced by a valid Local IP Address such as 192.168.xxx yyy or 10.0.xxx.yyy so quickly that you never even see the 169.254 Address.
If you do see the 169.254 Address, it can be read as "Nobody will talk to me" or "Nobody will give me an IP Address". When you have this IP Address for more than an instant, you should suspect bad cables for Ethernet connections, bad signal strength or interference for wireless, Router configuration problems, or Mac configuration problems.
Mac configuration problems are often solved by using the "Assist Me" button is System Preferences > Network and choosing to set up again.
Another diagnostic is to try using Network Utility and the Ping function, and Ping-ing the address of your Airport base Station, often 192.168.0.1 or 10.0.0.1 or similar. This will tell you if the Router is reachable, or there are cabling/wirelss signal problems.
In this case, proxies are not an issue, and are simply a distraction from the real problems.

Java doesn't bypass proxy for IPs using (IP-Subnet) combination ??

Dear All,
On Mac OS I am getting the below problem, I didn't tried it on Windows may be this problem may not occur there.
Problem:---
On Mac OS (Leopard).
When bypassing proxy IP in "Network Settings->Advanced...->Proxies->Bypass Hosts & Domains" field is given as IP-Subnet combination, e.g. 192.168.60/24, then in Java while trying to connect with HttpUrlConnection's connect() method, and then getting response code using HttpUrlConnection's getResponseCode() method it returns response code 407 i.e. Proxy is required. But safari works well for that,
This Java API works well when I directly give IP as 192.168.60.X it works (Java API) well.
I tried System.getProperties().setProperties("http.nonProxyHosts","192.168.60/24"), then also it doesn't works.
Please tell me any solution, suggestion or workaround or any document that tells it may not be done through Java API.

I think System.getProperties().setProperty("http.nonProxyHosts",any host name, IP with * or |) works well for Windows.
Now may be specifying the range of IPs using subnet on Mac OS (e.g.192.168.60/24) is different than on windows (e.g. 192.168.60/255.255.255.0) and therefore this fails on Mac OS. Although Java is given by Mac for its OS, but I think they didn't made any changes for this API.
Now the question is whether its a bug in Java Mac or there is some workaround present for that???
Do you have any idea that I am going right way or not??

NullPointer thrown with Applet.getParameter()?

Alright, I've got this error that's been driving me crazy, and knowing me, it's something small that I'm overlooking, so I'd like to apologize in advance for the fact that this is probably something very basic that I'm neglecting.
I'm writing an Applet that uses the <PARAM> tag to get some parameters. However, since I put this in, it throws a NullPointerException. Now, here's the thing that's got me really confuzzled: the NullPointer is thrown not in my method, but rather in java.applet.Applet.getParameter().
The line in my code:
clientID = getParameter("id");The line in the HTML that specifies this parameter:
<PARAM NAME=ID VALUE=4>I've tried it with quotation marks around the values in the PARAM tag, I've tried it with an upper-case String passed into getParameter (the API's say that it's case-insensitive, so that shouldn't matter), and I'm just generally confused about what it is that I'm doing wrong that is making getParameter() throw a NullPointerException.
Anyone know what I'm doing wrong?

Alright, I've been looking through this, and think I've found the problem: for some reason, my Applet isn't creating an AppletStub.
According to the source code for Applet (here), when I try to call getParameter, Applet just calles getParameter on its AppletStub. That's the only line in Applet.getParameter(), so it's the only place where a NullPointer would be thrown in Applet.getParameter().
Now, this also means that I'll run into the same problem if I try to use getCodeBase(), meaning that I can't try to get the URL, which should include the variables. And, since the whole point of what I'm trying to do is to allow variable URL's, I also can't hardcode the URL into my program and try to read the <PARAM> tags with a URLConnection.
So, it looks like my only hope is to somehow get AppletStub working. Does anyone know anything about AppletStub that might help? Please?

Bypassing proxy while connecting local servers

I have a proxy server 172.22.6.26 with port 80. This is set for http, https, ftp, socks, gopher in system preferences->network->ethernet->advanced->proxies.
I am running apache server from eclipse on my macbook pro. Macbook pro ip is 172.22.4.33. When I tried to fire a request using soap ui to http://172.22.4.33:8080/service, soap ui is throwing an exception saying ConnectionTimeoutException: Connect to 172.22.6.26
I dont want soap ui to connect to my local server through the proxy server. I checked the proxy setting for soap ui and it is not enabled.
How can I bypass proxy settings when a request is made to my localserver or to another apache server running on machine in same network(172.22.4.81)?
I tried putting 172.22.4.33, 172.22.4.81 in Bypass proxy settings for these Hosts & Domains: in system preferences->network->ethernet->advanced->proxies
Can anyone please help?

Hi..Thanks for your reply.
I tried what you mentioned. But still had the same issue.
Soap UI gives error as below

Bypass Proxy for Local Addresses

All-
With the new 2.0 software, I am now able to connect my 3G iPhone to the WiFi network at work. The network uses an authenticated proxy to get external access. I can access external sites just fine now, but I can't see internal sites. The proxy settings on my work desktop give me the option to "bypass proxy server for local addresses".
Is there any way to do this on an iPhone?
Right now I need to make a choice between access only internal sites or only external sites.
Thanks!

While not wanting to be a total weenie, ME TOO
After a bit of searching, the best we're going to be able to do right now is use a Proxy Auto-Config (.pac) file. I'm drawn to this conclusion from combining a lot of web searches with a peek at the "iPhone and iPod touch Enterprise Deployment Guide, Second Edition" (available at http://manuals.info.apple.com/enUS/Enterprise_DeploymentGuide.pdf, or via the Apple iPhone Enterprise support page at http://www.apple.com/support/iphone/enterprise/.
Setting the PAC file using the iPhone v2.x software is pretty direct - click the little arrow next to the network you want to configure, scroll down to the bottom where the proxy settings live. Choose "Auto" and enter the Auto-config URL.
That's the good news. The bad news is that I'm not entirely sure what that entails w.r.t. using one with the iPhone software. I'm not entirely clever enough to create such a file nor am I clever enough to know how to stick such a file onto my iPhone. I'm going to run this around my local team to see what they can come up with. If they come up with a solution (and it's simple enough for me to do AND explain), then I'll post a follow-up. Until then, good luck to you AND if you figure something out feel free to share with everyone else.

Printing with applet

hi
i am trying to print some text with applet but it is not working here is my code
sMsg="printing a applet is tough job";
// Find the default service
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
PrintService service[]= PrintServiceLookup.lookupPrintServices(flavor, null);
// Create the print job
byte[] b=sMsg.getBytes();
DocPrintJob job = service[0].createPrintJob();
Doc doc = new SimpleDoc(b, flavor, null);
try{
job.print(doc, null);
}catch(Exception e){System.out.print(e.getLocalizedMessage());}
it is not doing anything not even the error is displayed
when i execute this code i get dialog box which ask me to allow this applet to print or not but after that ,nothing happens.
plz help me.
thanks in advance.

Hans,
I came across a similar problem a few months ago. I came up with a work-around, and although it's not great, it met the demands of my current project.
A normal applet can't write files to a user's computer because that could create some big security problems. However, an applet can communicate with the server on which it's located. SO, I created a servlet that resides on the same server. When the user wants to print something from the applet, he clicks a Print button which opens a URLConnection and sends the data to the servlet. The servlet then creates an HTML document on the server and formats the data nicely. Then, back in the applet, I used this line to open a new browser window and show the HTML file:
getAppletContext().showDocument(new URL(theUrl), "_blank")
The user can then use the browser's print function to print the data.
I know it's kind of a roundabout way, but I was pressed for time. Let us know if you come up with something better.

Need help with applet servlet communication .. not able to get OutputStream

Hi,
well i am not able to get any value from connection.getOutputStream() and i doubt my applet is not able to hit the servlet. could you review my code and tell me if it has some bug somewhere. and more over i want to know how to send multiple file data from applet to servlet . i want some sample or example if possible.
do share if you have any experience of this sort..
Thanks.
