    <p>I have a pkcs12 file. I need to use this to connect to a webpage using https protocol. I came across some code where in order to connect to a secure web page i need to set the following system properties:</p> <pre><code>System.setProperty("javax.net.ssl.trustStore", "myTrustStore"); System.setProperty("javax.net.ssl.trustStorePassword", "changeit"); System.setProperty("javax.net.ssl.keyStoreType", "pkcs12"); System.setProperty("javax.net.ssl.keyStore", "new_cert.p12"); System.setProperty("javax.net.ssl.keyStorePassword", "newpass"); </code></pre> <p>I have the p12(pkcs12) file. All I need is a truststore file.</p> <p>I extracted the certificates using:</p> <pre><code>openssl.exe pkcs12 -in c:/mykey.p12 -out c:/cert.txt -nokeys -clcerts </code></pre> <p>Now converted the cert PEM file to der</p> <pre><code>openssl.exe x509 -in c:/cert.txt -outform DER -out c:/CAcert.der </code></pre> <p>Now adding the der file to a keystore</p> <pre><code>keytool -import -file C:/Cacert.der -keystore mytruststore </code></pre> <p>Now I have the truststore, but when I use it, I get the following error</p> <pre><code>Exception in thread "main" java.net.SocketException: java.security.NoSuchAlgorithmException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: com.sun.net.ssl.internal.ssl.DefaultSSLContextImpl) </code></pre> <p>Update: After removing certain properties and setting only the "trustStore", "trustStorePassword" and "trustStoreType" property, I got the following exception</p> <pre><code>java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty </code></pre> <p>Please Help.</p>

    2. COAnother thing to check is that your trust store location is correctly specified; if javax.net.ssl.trustStore is specified but doesn't exist, an empty trust store is created on the fly. Your new error message makes it sound like this could be happening.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
