Hi
I made a mistake in the earlier post, the error occurs due to line 33 not 29.

Thanks

Hi,
Here is a code that I copied from the web

/** * A simple example that uses HttpClient to perform a GET using Basic * Authentication. Can be run standalone without parameters. * * You need to have JSSE on your classpath for JDK prior to 1.4 * * @author Michael Becke */ public class BasicAuthenticationExample { /** * Constructor for BasicAuthenticatonExample. */ public BasicAuthenticationExample() { super(); } public static void main(String[] args) throws Exception { HttpClient client = new HttpClient(); client.getState().setCredentials( new AuthScope("an https address", 443), new UsernamePasswordCredentials("login id", "password") ); GetMethod get = new GetMethod( "an https address which points to a file"); get.setDoAuthentication( true ); try { // execute the GET int status = client.executeMethod( get ); // print the status and response System.out.println(status + "\n" + get.getResponseBodyAsString()); } finally { // release any connection resources used by the method get.releaseConnection(); } } }

Because of line 33 I get this error
Exception in thread "main" javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.fatal(Unknown Source) at com.sun.net.ssl.internal.ssl.Handshaker.fatalSE(Unknown Source) at com.sun.net.ssl.internal.ssl.Handshaker.fatalSE(Unknown Source) at com.sun.net.ssl.internal.ssl.ClientHandshaker.serverCertificate(Unknown Source) at com.sun.net.ssl.internal.ssl.ClientHandshaker.processMessage(Unknown Source) at com.sun.net.ssl.internal.ssl.Handshaker.processLoop(Unknown Source) at com.sun.net.ssl.internal.ssl.Handshaker.process_record(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readRecord(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.performInitialHandshake(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.writeRecord(Unknown Source) at com.sun.net.ssl.internal.ssl.AppOutputStream.write(Unknown Source) at java.io.BufferedOutputStream.flushBuffer(Unknown Source) at java.io.BufferedOutputStream.flush(Unknown Source) at org.apache.commons.httpclient.HttpConnection.flushRequestOutputStream(HttpConnection.java:828) at org.apache.commons.httpclient.HttpMethodBase.writeRequest(HttpMethodBase.java:2116) at org.apache.commons.httpclient.HttpMethodBase.execute(HttpMethodBase.java:1096) at org.apache.commons.httpclient.HttpMethodDirector.executeWithRetry(HttpMethodDirector.java:398) at org.apache.commons.httpclient.HttpMethodDirector.executeMethod(HttpMethodDirector.java:171) at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:397) at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:323) at BasicAuthenticationExample.main(BasicAuthenticationExample.java:50) Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at sun.security.validator.PKIXValidator.doBuild(Unknown Source) at sun.security.validator.PKIXValidator.engineValidate(Unknown Source) at sun.security.validator.Validator.validate(Unknown Source) at com.sun.net.ssl.internal.ssl.X509TrustManagerImpl.validate(Unknown Source) at com.sun.net.ssl.internal.ssl.X509TrustManagerImpl.checkServerTrusted(Unknown Source) at com.sun.net.ssl.internal.ssl.X509TrustManagerImpl.checkServerTrusted(Unknown Source) ... 18 more Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at sun.security.provider.certpath.SunCertPathBuilder.engineBuild(Unknown Source) at java.security.cert.CertPathBuilder.build(Unknown Source) ... 24 more

Now the reason for this error is of course that the certificate sent by my server is not already in my list of trusted certificates.
My question is how to get the certificate into the trusted list.

Thanks

Hi
I want to download a file from a server over https, I get the following error

I have the URL of the file and I use URLConnection.

Thanks

@Paul Clapman -- My mistake. I meant that I want to pack my code maybe as an exe for windows or dmg for mac (I have already tried the obvious executable jar)

@Campbell Ritchie -- Thanks for the link. I have been looking at Java web start, but for my code to really work well, I'd like my code to run as a windows service and whatever the equivalent of that in other OS are. But as far as I have understood applications based on Java web start need some kind of user intervention to start (if say the pc was shutdown)

Hi
I have a very basic question.
I have a java application that currently starts via a main program. I want to distribute it to clients so that the application runs on all platforms continuously in the background.
I saw java service wrapper, but I couldn't figure out how to make a distributable file out of it.
I guess java web start would be another solution, but then again how do I make my application run in the background non stop (if it stops then I'd like the OS to restart it....much like a service).
Spent a whole day googling for the answer, but can't find a viable solution.

Thanks
