    <p>I am running into a Java security problem. I have an agent which uses the pdfbox-1.7.1.jar to decrypt a PDF whose password I know. The jar has been placed in /jvm/lib/ext on both the server and my client, and I get this little beauty of a stack trace:</p> <pre><code>java.lang.SecurityException at java.lang.SecurityManager.checkPermission(SecurityManager.java:582) at COM.ibm.JEmpower.applet.AppletSecurity.checkSecurityPermission(AppletSecurity.java:1332) at COM.ibm.JEmpower.applet.AppletSecurity.checkPermission(AppletSecurity.java:1613) at COM.ibm.JEmpower.applet.AppletSecurity.checkPermission(AppletSecurity.java:1464) at java.lang.SecurityManager.checkSecurityAccess(SecurityManager.java:1725) at java.security.Security.insertProviderAt(Security.java:190) at java.security.Security.addProvider(Security.java:210) at org.apache.pdfbox.pdmodel.encryption.SecurityHandlersManager.getInstance(SecurityHandlersManager.java:146) at org.apache.pdfbox.pdmodel.PDDocument.openProtection(PDDocument.java:1365) at org.apache.pdfbox.pdmodel.PDDocument.decrypt(PDDocument.java:798) at com.magerman.hremail.prep1docc.PDFDecryptor.decrypt(Unknown Source) at com.magerman.hremail.prep1docc.MetaAttachment.decrypt(Unknown Source) at com.magerman.hremail.prep1docc.MetaDocContainingAttachments.removePasswordOfPDFAttachments(Unknown Source) at com.magerman.hremail.prep1docc.EPDFPreparerFactory.generateAttachmentsTriggerDocs(Unknown Source) at com.magerman.hremail.prep1docc.EPDFPreparerFactory.run(Unknown Source) at com.magerman.hremail.prep1docc.BaseClass.NotesMain(Unknown Source) at lotus.domino.AgentBase.runNotes(Unknown Source) at lotus.domino.NotesThread.run(Unknown Source) </code></pre> <p>Both Client and Server are using 8.5.3. The Agent security level is set to 3. Putting the jars in the agent itself does not help. The signer of the agent is full admin on the server. The security exception seems to point at "insertProviderAt" </p> <p>This is what I tried:</p> <p>putting </p> <pre><code>grant { permission java.security.AllPermission; } </code></pre> <p>solves my problem, but I will never get this past my eagle-eyed admin. </p> <p>I am trying to reduce the scope of the permission to just the database but the documentation here: <a href="http://docs.oracle.com/javase/7/docs/technotes/guides/security/PolicyFiles.html" rel="nofollow">http://docs.oracle.com/javase/7/docs/technotes/guides/security/PolicyFiles.html</a> did not really tell me how to input a notes database.</p> <p>I looked into Stephan Wissel's article on Xpages Java security here: <a href="http://www.wissel.net/blog/d6plinks/SHWL-8JYAT5" rel="nofollow">http://www.wissel.net/blog/d6plinks/SHWL-8JYAT5</a> and inserted the following into my /jvm/lib/security/java.policy file:</p> <pre><code>grant codeBase "xspnsf://server:0/development/hre-mail/hre-mail2_0/hre-mail_(2_0)_dev.nsf/-" { permission java.security.AllPermission; }; </code></pre> <p>but that did not work either, I suppose because my codeBase syntax is not valid for the nsf database but only for webpages.</p> <p>I am also trying to reduce the Permission to that which is really needed, and looking at the documentation here: <a href="http://docs.oracle.com/javase/1.4.2/docs/guide/security/permissions.html" rel="nofollow">http://docs.oracle.com/javase/1.4.2/docs/guide/security/permissions.html</a></p> <p>implies that I have to do something like</p> <pre><code>java.security.SecurityPermission "insertProvider.{name}" </code></pre> <p>but I have no idea what {name} should be.</p> <p>I also read Mikkel's article on <a href="http://lekkimworld.com/2013/06/20/java_in_notes_domino_explained_on_java_security_and_how_it_relates_to_notes_domino.html" rel="nofollow">http://lekkimworld.com/2013/06/20/java_in_notes_domino_explained_on_java_security_and_how_it_relates_to_notes_domino.html</a></p> <p>but my brain fried at about the middle of the page. In particular, I am not sure how to actually implement this method. Could you hold my hand and walk me through please?</p> <p>Whilst I'm at it, am I right in assuming that whenever I put new jars in /jvm/lib/ext, all I need to do is a </p> <pre><code>tell http restart </code></pre> <p>to have the JVM reload? I am assuming Domino is using a single JVM for Xpages, Agents, and the HTTP Task, is this right.</p> <p>Also, am I right that I need to restart the server for any new policies in java.policy to be effective?</p> <p>Any ideas? </p>

    1. COWhat is the actual security exception that is failing? What security level do you have your agent at? In the last xspnsf part, did you try moving the jars into the NSF? What version of Domino?

    2. CORe your last assumption: web agents (i.e., executed webQueryOpen, webQueryOpen, or ?OpenAgent) run in the HTTP task's JVM. Scheduled and triggered agents run in a separate JVM in the AMGR task. I haven't done xpages work, so I'm not sure if they share the same JVM as web agents.

    3. CO@Richard - This is new to me, thanks. So there is at least 2, perhaps 3 JVMs running, and the security settings apply to all of them? Also, as tell http restart restarts the JVM(s), it's even more confusing to little old me.

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.
