Topic:
Java Programming Language;JavaScript;PHP Scripting Language
I get one applet java application and I am using it in IE every day.
Now I would like to save the data I want from the application through
the proxy , now I am using Charles debugger proxy.
From the Sun document,http://docs.oracle.com/javase/6/docs/technotes/guides/net/proxies.html, it mention set the java for proxy at command line.
I tried it at my PC at C:/program files/java/jre7/bin/java -D http.proxyHost=127.0.0.1 -D
http.proxyPort=8888, but it doesn't work, just error Can't find the variable
And I try to use javascript,
<html>
<head>
</head>
<COMMENT><SCRIPT LANGUAGE="JavaScript1.1"><!--
java.lang.System.getProperties().put("http.proxyHost", "127.0.0.1");
java.lang.System.getProperties().put("http.proxyPort", "8888");
var javaVersion = java.lang.System.getProperty("java.version");
alert(javaVersion);
//--></SCRIPT></COMMENT>
<body>
</body>
</html>
Firefox reports,
Error: uncaught exception: java.security.AccessControlException: access denied ("java.util.PropertyPermission" "*" "read,write")
and only alert(javaVersion) is working.
I already open or run Charles proxy software and its client adress is set 127.0.0.1:8888
before I do the previous action and Charles running is fine from IE and Firefox.
But it doesn't show any information data I want from my applet application that is
probably related to those proxy setting for Java proxy is not correct.
And my PC I login in as adminstrative manager mode already
Any advise to solve the issue, I am not familar with java code and if provide
the simple code for setting system proxy property for Java that is
strongly welcome.
Please advise

Because usually a jar file only contains class files

Okay, talk it into otherway or reverse the question to you.
On you example, after typing something in the applet, it will receive message

is able to capture the link response from http://www.cehjohnson.btinternet.co.uk/protean/speedtest.txt?dummy=8505545161610364928

On your example, I try it type something and click start on the applet, the applet
will receive the data from the link at
http://www.cehjohnson.btinternet.co.uk/protean/speedtest.txt?dummy=8505545161610364928
And Charles is about to capture the response from the link.
On my case, the applet

<param name=cabbase value="Proj.cab">
<PARAM NAME="archive" VALUE="Proj.jar">
<PARAM NAME="java_arguments" VALUE="-Xmx512m -Dsun.java2d.noddraw=true">
Charles could not capture anyting from any link created by my applet , no matter what
I type in the applet. SO the answer Java applet code for my side is mysterous.
And doesn't know what protocal it is using for transmitted between applet and remote site.
So anyway, getting close, I could download the java archive of Proj.jar and do some Java code reversing to see what happen

My case is similar to your example, the stream data from remote into applet automatically after success login.
Possibly. I can't comment precisely as i don't know exactly what your applet does. Mine happens to 'stream' via http.So the codebase is remote site stream data location, RIght ?
Again, i can't answer that exactly without knowing what your applet is doing, so the answer is - probablyAnd achive is Java applet program to be ready to receive data on my IE from remote site
stream data location, Right ?
The applet essentially IS the archivestream data location, Right ?
At this stage, i suggest you get my applet working with your proxy setup. If you can do that, you'll at least have a chance with your own.

As we know Charles is http proxy only so other TCP protocol data transfer
can not be captured by Charles, Right ?
In general, that's probably right, as i said HERE
But i think it would depend on what the applet is doing internally, which still remains very mysterious

SO the answer using other ways besides Charles to capture the stream data

Charles is an http proxy. Any network streams that don't use http will not register with it at all
Author: duncanb7 replied at 2024-07-05 02:51:59
Charles is working on IE, and I 've already checked on IE's tools--> connection which already
select proxy for 127.0.0.1:8888
When open remote site on IE, Charles is able to show all http info and re-direct link except the streaming data into applet.
Actually, all data from DSL or telephone line should be able to be captured by
program software on widow such as C, Java program.
Is it right ?
Why charles can not capture the stream data if it is using http protocal unless
the stream data is transferred from other protocal such ftp, RIght?
I google 8044 port which mention

I don't need to download Charles - i've used it many times and recommended it here.
The confusing part is that there's an applet in the scenario. Unless the applet picks up the correct proxy settings from the hosting software (applet context etc.) then it won't use the proxy. With any luck, it will.
The first thing you need to do is set Charles as the proxy for the browser. Do that, close the browser instance, restart with Charles running and let me know what happens

If you are keeping confusing, just download Charles debugging software, and
login your www.experts-exchange.com account, Charles will show you something,
and imagine experts-exhange.com will send you something after login successfully
, for example, one applet java code, and then.......
You can try Fiddle and Charles, just type it in google seach

a-I need to login remote website and type login and passward , just a form html page,
at this moment all link is captured by Charles.
b- after login successfully remote stie will send one html page which will included
apple tag and some javascript coding and then Java applet application is enabled and
streaming non-stop data is showing on the application
After that, Charles is not able to capture anything again from the remote site.
THe scenario is simple not confusing, Right.

it seems point (1) and (2) are address to take care of streaming data
transferring into applet Java which recevied the data and show it to users.

OK, so the applet makes a network connection and you want it to make it through the proxy?
Author: duncanb7 replied at 2024-07-04 11:37:57
Yes. the application is running in IE browser. Charles can trace the address
only for http/https from browser. If the data is streaming data into applet java application in IE, Charles is not able to grab the streaming data. That is why I want to
set the applet java 's proxy to let all data going into Charles first before going to
the applet application.
SO I want as follows to do so,
C:/program files/java/jre7/bin/java -D http.proxyHost=127.0.0.1 -D
http.proxyPort=8888 but it is not working.
Now I am try to re-write the java.policy file to grant all file access right to the users
such as system property like http.proxyHOST, but access file right on window is
getting issue. May be I need to re-install all java in my directory instead of
"program files" on window

http.proxyPort=8888 but it is not working.
Now I am try to re-write the java.policy file to grant all file access right to the users
such as system property like http.proxyHOST, but access file right on window is
getting issue. May be I need to re-install all java in my directory instead of
"program files" on window
Please advise

This is confusing. Forget the proxy issue at the moment
