Using HttpsURLConnection

Hello evertbody I have a problem programming a channel, I'm using Portal 6.1 running under Applicatrion Server 7, also in this instance is running Identity Server.
The channel must connecto to a utl using https, but URL.openConnection return a
com.iplanet.services.comm.https.HttpsURLConnection
insted of a javax.net.ssl.HttpsURLConnection, I have been reading and this is because the
-Djava.protocol.handler.pkgs=com.iplanet.services.comm
in the Application Server JVM Settings, so how can I get a javax.net.ssl.HttpsURLConnection, or what should I do, i can't find any documentation for the com.iplanet.services.comm.https.HttpsURLConnection class
Thanks for your help

Are you using the URL-Sraper Channel?
if Yes =>
Does it work properly with a "normal" HTTP connection to
another resource ?
You might have a problem with the proxy settings.

How to call a WebService method using HttpsURLConnection?

Hi,
I want to know how i could use HttpsURLConnection to call a WebService method.
I can use the following:
String endpoint = "https://xyz:8443/axis/services/MSecurity";
System.setProperty("javax.net.ssl.keyStore", keyStorepath);
System.setProperty("javax.net.ssl.keyStoreType", "PKCS12");
System.setProperty("javax.net.ssl.keyStorePassword", keyStorePassword);
System.setProperty("javax.net.ssl.trustStore", trustStorePath);
System.setProperty("javax.net.ssl.trustStoreType", "JKS");
System.setProperty("javax.net.ssl.trustStorePassword", trustpass);
//Call Web Service
URL url = new URL(endpoint);
MSecuritySoapBindingStub service = new MSecuritySoapBindingStub(url, null);
//get list of people
String[] vo = service.getVO();
for (int i = 0; i < vo.length; i++) {
System.out.println(vo);
However, loading my cert. this way is not flexible. Therefore, I am using SSLContext to initialize my keystore and truststore and then I am using the following to connect to my webservice:
SSLContext sc = SSLContext.getInstance("SSLv3");
sc.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
SSLSocketFactory ssf = sc.getSocketFactory();
URL url = new URL(endpoint);
HttpsURLConnection htp = (HttpsURLConnection) url.openConnection();
htp.setSSLSocketFactory(ssf);
However, I do not know how I could use the "htp" object to call the getVO() method above.

Use Apache Axis to do SOAP in Java.
Nobody can just mail you the code. You first have to create java source files from the web service via its WSDL file.

ClassCastException using HttpsURLConnection with Tomcat 4.1.27

Hi,
I try to open an SSL connection using HttpsURLConnection that works fine with a standalone application (see code fragment):
import javax.net.ssl.HttpsURLConnection;
import java.net.*;
import java.io.*;
URL website = new URL( "https://aSampleSSLSite" );
HttpsURLConnection connection = ( HttpsURLConnection ) website.openConnection();
Using the same code in Tomcat 4.1.27 and Struts 1.1 throws a java.lang.ClassCastException while trying to use website.openConnection().
What is the difference?

Hi,
I'm using JDK 1.4.2 and haven't installed JSSE separately at all. Actually I really use javax.net.ssl.HttpsURLConnection. However, I tried com.sun.net.ssl.HttpsURLConnection as well and got a 'java.net.SocketException: Default SSL context init failed' instead of.
Oddly enough the code works fine in a standalone application.

Post using HttpsURLConnection

VM: 1.4.x
Container: JBoss 4.x (Servlet)
I'm trying to POST to a trusted site using HttpsURLConnection, but I'm not sure what the format of the request params is. I have tried the GET-style as in:
name1=value1&name2=value2and line separated as in:
name1=value1\n
name2=value2\nbut none seem to work. My suspicion is that the parameters are malformed. Here is the code (note the loop):
HttpsURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "text/html; charset=UTF-8");
conn.setDoInput(true);
conn.setDoOutput(true);
while(keys.hasNext()){
    String name = (String)keys.next();
    String value = (String)data.get(name);
    char ch = keys.hasNext()?'&':'\n';
    postData.append(name + "=" + URLEncoder.encode(value, "UTF-8") + ch);
out = new PrintWriter(conn.getOutputStream());
out.print(postData.toString().getBytes());
out.flush();Then use BufferedReader to read the response, which seems to be working fine.
My questions is, how should the request params be printed in a (SSL) POST request?
Thanks

Hi,
there is a library called HTTPClient available for free on:
http://jakarta.apache.org/commons/httpclient/
It supports time out, besides a bunch of other features.
Also HTTPS is straight forward, as soon as the underlying JSSE
installation is done.

Tunneling Problem using HttpsUrlConnection

Hi,
I had gone through forums regarding this topic and still i am facing the same problem using the HttpsUrlConnection. We are working behind a proxy so we have to make a proxy authorization if we want to connect to a server in the internet.
But in case of HttpUrlConnection, everything works
fine. But if we do the same with a HttpsUrlConnection, the authentication fails. It throws an IOException
with the message
Unable to tunnel through 192.9.100.10:80.
Proxy returns "HTTP/1.1 407 Proxy authentication required"
Sample code as follows,
The following code doesn't have any problem becos it works fine with HttpUrlConnection and also it is working without proxyserver for https as well.
This is running under MSVM.
I don't want to use SSLSocketFactory and i need to use following layout(i.e only with Httpsurlconnection)
Is there any way to make work with proxyserver? Or can't we do this at all?
System.setProperty("proxySet","true");
System.setProperty("https.proxyHost","proxyIP");
System.setProperty("https.proxyPort","80");

Can any one help me regarding this?I need a reply very urgently.

Hope this help.
Note to change the properties to fit your system, and use the supported package ( JSSE, JRE1.5.......).
You can use URLConnection for both HTTP or HTTPS protocol.

Classcast exception while using HttpsURLConnection

I am using java1.3. I have downloaded all the jars in JSSE..however when i am using the HttpsURLConnection class i get ClassCase exception at
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
I don't get any error while compiling however get the error when executing
Any help on this will greatly appricated.
Thanks
Sudha

Magic, that worked for me.
Now the real question is why did it work. My code worked fine under JRE 1.3.1, but when I remove jsse.jar from my classpath and upgraded to JRE 1.4.1 it broke. By commenting out the System.setProperty it now works. Strange.
Cheers,

Using HttpsURLConnection Error - from Web Dynpro

I have this case where I need to connect to a https site using SSL api.
I'd created a java class to connect to the https site using the normal "javax.net.ssl" package provided by J2SE api. And this work successfully.
However, there will be a problem if i trigger an action from the view to call for this java class, there will be an error.
One thing which i found weird is :
1.) If i use the normal java class to connect to the https site, it uses this connection protocol :
sun.net.www.protocol.https.DelegateHttpsURLConnection:https://server/test/test1.jsp (Works successfully)
But
If I call this java class from a view, it uses this connection protocol :
iaik.protocol.https.HttpsURLConnection:https://server:443/test/test1.jsp (Unable to work)
How am i to make the web dynpro to use this "javax.net.ssl" api? I tried removing two of these library file :
iaik_jsse.jar
iaik_ssl.jar
but the error still occurs.
Does anyone have any idea how to solve this problem? Thanks.

Hi jo lum

Help downloading a file using HttpsURLConnection

Hi All,
I am trying to connect to a page that is actually a cgi page and download a file from there using the httpsURLConnection.
When I run the URL from the browser, I get an authentication challenge...I authenticate, then I get the Download file box where I can download the file.
When I run my code to connect to the URL using the httpsURLConnection, I'm able to authenticate using post then what comes back is the html for the front page. (like an index page or something).
Is this even possible? Any help would be greatly appreciated.
Here's some of the code...
URL url = new URL ("https://.... /file.cgi?.....");
HttpsURLConnection c = null;
c = (HttpsURLConnection)url.openConnection();
c.setRequestMethod("POST");
c.setRequestProperty("Authorization", "Basic " + BasicAuth.encode(user, password));
c.setRequestProperty("User-Agent", "Mozilla/4.0(compatible)");
c.setRequestProperty("Content-Disposition", "attachment;filename=\"events.csv\"");
c.setRequestProperty("Content-Type", "application/x-csv");
c.setRequestProperty( "Accept", "application/x-csv");
c.connect();
//System.out.println(c.getContentEncoding());
System.out.println("Response code: " +c.getResponseCode());
InputStream in = c.getInputStream();
StringBuffer b = new StringBuffer();
BufferedReader r = new BufferedReader(new InputStreamReader(in));
String line;
while ((line = r.readLine()) != null)
b.append(line);
String s = b.toString();
System.out.println(s);

I just noticed that the page it brings back is exactly the page that I get in the browser when I do not type the attributes after the https://---.cgi?.
For example the url is ....cgi?subcmd=Download
So, is there some place I can set these attributes within the java code that isn't in the url field?

Using keytool to import a certificate

I'm trying to import in the samplecacerts file a seft signed certificate generated for test purposes on my test web server.
The command I issued was:
keytool -import -alias mycert -file mycert.cer -keystore samplecacerts -trustcacert -storepass changeitand the answer was:
keytool error: Signature not availableIf I accept this certificate using my class that implements the interface X509TrustManager and getting data using HttpsURLConnection all works fine.
I used two methods to export the certificate:
1. I exported it after accepting it in Ienternet Explorer
2. I wrote it from the method isServerTrusted as suggested by Aseem in his sample code (http://forum.java.sun.com/thread.jsp?forum=9&thread=14884&start=25&range=1&hilite=false&q=)
The two generated files are identical.
Anyone can help me?
Thank
Aldo

I am having the same problem - and I don't understand the one reply you got.
So here goes. WHY can I easily import a self-signed certificate as a "trusted root" in IE, but I cannot import the same certificate into my cacerts file using keytool.exe? Keytool always gives the error, "Signature not available".
Can someone please tell me what the heck I am supposed to do? All I want to do is be able to connect to an https URL in my Java code and read the contents. I "trust" the darn server, but the keytool utility doesn't seem to "trust" me....
BTW, yes I am using JSSE, it's not a code problem it's a keytool problem.

ClassCastException in HttpsURLConnection

I try to connect to https://verisign.com using HttpsURLConnection..and i get :

     String inputLine;
     while ((inputLine = in.readLine()) != null)
     System.out.println(inputLine);
     in.close();
Is this problem connected with wrong certificate?
But why is it a CastException?
Please help thanks.

Had this one.
You probably use the new class:
javax.net.ssl.HttpsURLConnection and verisign uses
older com.sun.net.ssl.HttpsURLConnection.

Error 500: com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection
in line
conn = (javax.net.ssl.HttpsURLConnection) url.openConnection();
Where is the problem ??

Sorry, should have been:
javax.net.ssl.trustStore=path/to/etc/etc/DummyServerTrustFile.jks
javax.net.ssl.trustStorePassword=WebAS
Didn't get it to actually work like that though. trustStore & trustStorePassword were always null when I ran my program under WAS5.1.
Here is what I did. If running from command line using WAS5.1 as JRE, first setup the environment:
set JAVA_HOME=C:\Program Files\IBM\SDP70\runtimes\base_v51\java\jre
java -Djava.protocol.handler.pkgs=com.ibm.net.ssl.internal.www.protocol myProgramIndependent of whether running from command line or in RAD7, code in program:
System.setProperty("javax.net.ssl.trustStore",
"C:\\Program Files\\IBM\\SDP70\\runtimes\\base_v51\\etc\\DummyServerTrustFile.jks");
System.setProperty("javax.net.ssl.trustStorePassword","WebAS");(would be better to be able to specify trustStorePassword in WAS than in code though,
but works as such)
One can use some other file but I just added the certificate to DummyServerTrustFile.jks.
Then, unlike I said, one CAN use the HttpsURLConnection, like this:
com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection conn = null;
URL urli = new URL("https://some.address.com");
conn = (com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection)urli.openConnection();
Note this uses classes from C:\Program Files\IBM\SDP70\runtimes\base_v51\java\jre\lib\ibmjsseprovider.jar, so it needs to be in classpath when compiling.
Now this way I didn't get a cast exception from using HttpsURLConnection. The point is one can't instantiate javax.net.ssl.HttpsURLConnection, because RAD7's WAS5.1 can't cast it into its own class (wish it could).
Also, I still couldn't use the javax.net.ssl.HttpsURLConnection.setHostnameVerifier method, because com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection doesn't have it... So the result was pretty much the same as using a HttpURLConnection as I previously instructed. Well, I don't really need that method in practice, but I suppose one might need it in some situation. The IBM URL I quoted said WAS5.1 doesn't really compare DNS host name with the certificate host name though, so I suppose one doesn't need to programmatically set a dummy HostnameVerifier in WAS5.1.

ClassCastException while instantiate HttpsURLConnection

When I try to instantiate an HttpsURLConnection from an URL instance called "Server,"
HttpsURLConnection conn =(HttpsURLConnection) server.openConnection();I got the following exception:
java.lang.ClassCastException: sun.net.www.protocol.http.HttpURLConnection incompatible with javax.net.ssl.HttpsURLConnection
May I know if there is anyway to solve it? I have to use HttpsURLConnection.
Thank you!

Hi,
you did not provide your import statements contained in the class. Please check which class named HttpsURLConnection you are trying to import.
Maybe your import refers to sun.net.www.protocol.http..., which is imcompatible with the one in javax.net.ssl....
Bye.
