    <p>I have a application I am working on that deals with handling certificates and I am running into a issue where my code works correct when I run in via JUnit tests locally on my laptop but when I actually deploy the code to my server I am getting a exception. The exception is happening while creating a PublicKey from a RSA public key stored in a String. I am hoping someone might be able to point me in a direction to look why it fails on the server but works in the Junit.</p> <p>My RSA Public Key:</p> <pre class="lang-none prettyprint-override"><code>-----BEGIN PUBLIC KEY----- MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAvNEz3+TStAAndHTc1qwT NGvZYyB7DD1FshQf+mbQUGJ9HccOXNn5oHB7fWQjODjlDrYyCs7FclSMTLxA3lHX 98QWeWHL2O8t8qrJQQEUWZITmr/ddiNJOOvMeYF0K5if4m84vjgx/pTwwAVyU0Yo MMXPnRozO8o7zSyRsH4jixALDugrsveEjLQI/cIEFvNjqlhyfumHyJKywNkMH1oJ 4e/f89FkpeDV694lsLs1jguuLLnvroXYJ5Uzeos+F0Pj1zFDUvhWrjVwxsUfAxS8 5uFGTUm6EEl9XiKwi+mgg8ODrY5dh3uE2yKB2T1Qj8BfK55zB8cYbORSsm6/f6Bi BwIDAQAB -----END PUBLIC KEY----- </code></pre> <p>My Junit Code: &lt;- Works from laptop</p> <pre><code>@Test public void testkey() throws Exception { String pem = "-----BEGIN PUBLIC KEY-----"+ "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAvNEz3+TStAAndHTc1qwT"+ "NGvZYyB7DD1FshQf+mbQUGJ9HccOXNn5oHB7fWQjODjlDrYyCs7FclSMTLxA3lHX"+ "98QWeWHL2O8t8qrJQQEUWZITmr/ddiNJOOvMeYF0K5if4m84vjgx/pTwwAVyU0Yo"+ "MMXPnRozO8o7zSyRsH4jixALDugrsveEjLQI/cIEFvNjqlhyfumHyJKywNkMH1oJ"+ "4e/f89FkpeDV694lsLs1jguuLLnvroXYJ5Uzeos+F0Pj1zFDUvhWrjVwxsUfAxS8"+ "5uFGTUm6EEl9XiKwi+mgg8ODrY5dh3uE2yKB2T1Qj8BfK55zB8cYbORSsm6/f6Bi"+ "BwIDAQAB"+ "-----END PUBLIC KEY-----"; PublicKey willNotWork = decodeKey(pem); } </code></pre> <p>My Actual Code: &lt;- Throws exception when run on server</p> <pre><code>@Override public PublicKey getKey() { PublicKey pk = null; try { String crt = "-----BEGIN PUBLIC KEY-----"+ "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAvNEz3+TStAAndHTc1qwT"+ "NGvZYyB7DD1FshQf+mbQUGJ9HccOXNn5oHB7fWQjODjlDrYyCs7FclSMTLxA3lHX"+ "98QWeWHL2O8t8qrJQQEUWZITmr/ddiNJOOvMeYF0K5if4m84vjgx/pTwwAVyU0Yo"+ "MMXPnRozO8o7zSyRsH4jixALDugrsveEjLQI/cIEFvNjqlhyfumHyJKywNkMH1oJ"+ "4e/f89FkpeDV694lsLs1jguuLLnvroXYJ5Uzeos+F0Pj1zFDUvhWrjVwxsUfAxS8"+ "5uFGTUm6EEl9XiKwi+mgg8ODrY5dh3uE2yKB2T1Qj8BfK55zB8cYbORSsm6/f6Bi"+ "BwIDAQAB"+ "-----END PUBLIC KEY-----"; System.out.append("crt == " + crt); pk = decodeKey(crt); } catch(Exception ex){ System.out.println("getKey caught: " + ex.getMessage()); } return pk; } </code></pre> <p>decodeKey code:</p> <pre><code>public PublicKey decodeKey(String text) throws CryptographyException { String content = text; if( text.contains("-----BEGIN PUBLIC KEY-----") ) { content = text.replace("-----BEGIN PUBLIC KEY-----", "").replace("-----END PUBLIC KEY-----", ""); } if( text.contains("-----BEGIN RSA PUBLIC KEY-----") ) { content = text.replace("-----BEGIN RSA PUBLIC KEY-----", "").replace("-----END RSA PUBLIC KEY-----", ""); } byte[] der = Base64.decodeBase64(content); return decodeDerKey(der); } public PublicKey decodeDerKey(byte[] publicKeyBytes) throws CryptographyException { try { KeyFactory factory = KeyFactory.getInstance("RSA"); PublicKey publicKey = factory.generatePublic( new X509EncodedKeySpec(publicKeyBytes)); return publicKey; } catch(Exception e) { throw new CryptographyException(e); } } </code></pre> <p>Here's the exception that is thrown when I run my code on the server:</p> <pre class="lang-none prettyprint-override"><code>Could not parse certificate: java.io.IOException: DerInputStream.getLength(): lengthTag=111, too big` </code></pre> <p>So I am guessing is has to be some sort of difference between my laptop and the server. I have verified that both are running basically the same version of Java ("1.7.0_17"). I also checked the provider of the <code>KeyFactory</code> and they are the same as well. So where do I look from here? </p>

    1. COWhat happens if you run exactly the same code on both machines? It would be nice to remove any JUnit interference from the test. Also, it would help us if you can tweak your code into an [SSCCE](http://sscce.org/) so that we can test easier. You have undefined string constants and exceptions in your code above.

    2. COUpdated the string constants. Thanks for the reference to SSCCE. If I place the Junit function on the server and run it as normal code, I get the exception. I am unable to run the other code locally because it is part of a web service that is deployed and so can't be debugged locally.

    3. COIssue was somewhere completely different. Or I should say, issue was between keyboard and chair :)

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.
