NullPointerException: currentDesign.getDoctype(currentStyle).toRequest(request) - AEM/Adobe CQ5

NullPointerException:  currentDesign.getDoctype(currentStyle).toRequest(request) - AEM/Adobe CQ5

We were getting the NullpoiterException while accessing the pages in Adobe Experience Manager(AEM)

Caused by: java.lang.NullPointerException
at javax.servlet.http.HttpServlet.service(
... 117 more

NullpointerException is thrown while getting the Doctype of the page design.

if (currentDesign != null) {

This issue was getting resolved after restarting the server.

After analysis the currentDesign  and currentStyle objects are not null and getDoctype method is throwing NullpoiterException.

The currentStyle  refers to the path (currentStyle.getPath())- /etc/designs/default.

By default /etc/designs/default/jcr:content path will not have cq:doctype property specified.

To resolve the issue we have added the  cq:doctype - html_5 property to /etc/designs/default/jcr:content


If the property is already available then delete the same and add again.

How to enable SSL debug tracing in Weblogic Server?

How to enable SSL debug tracing in Weblogic Server?

Add the following start up options to the start up file startWebLogic.cmd/ or startManagedWebLogic.cmd/ based on which file is used to start the server to enable SSL debug tracing in Weblogic Server.

JAVA_OPTIONS="${JAVA_OPTIONS} -Dweblogic.debug.DebugSecuritySSL=true -Dweblogic.debug.DebugSSL=true -Dweblogic.StdoutDebugEnabled=true -Dweblogic.log.StdoutSeverityLevel=Debug -Dweblogic.log.LogSeverity=Debug"

Invocation of https/SSL service is not working from OSB

Invocation of https/SSL service is not working from OSB

We were trying to install the wildcard certificate to enable the communication from OSB to end system, but the following exception was displayed in the log file and also the communication to the end system is failing even though the certificate installation was successful;

<Jan 23, 2015 10:45:05 PM PST> <Notice> <Security> <localhost> <AdminServer> <[ACTIVE] ExecuteThread: '12' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <> <bac54c313ca42523:46f5522b:14b61066510:-7ffd-000000000008b798> <1423456801909> <BEA-090898> <Ignoring the trusted CA certificate "CN=*,O=Sample,L=Sample,ST=Sample,C=US". The loading of the trusted certificate list raised a certificate parsing exception PKIX: Unsupported OID in the AlgorithmIdentifier object: 1.2.840.113549.1.1.11.> 
After analysis, we found that JSSE flag should be enabled along with Custom Host Name Verification ( to support wildcard certificate.


 After enabling the JSSE flag, none of the https communication from OSB is working but https communication from BPEL is working fine even with the wildcard certificate(BPEL and OSB is running in the same server).

The following exception is thrown while invoking the https service from OSB.

<soapenv:Envelope xmlns:soapenv="">
BEA-380000: General runtime error: java.lang.NullPointerException
<con:fault xmlns:con="">
General runtime error: java.lang.NullPointerException

This is the internal OSB server issue; the cause of the issue is that the AsyncResponseHandler does not properly register JSSEFilter for JSSE SSL.
The Weblogic patch 11866509 based on the Weblogic server version (this issues is identified in Weblogic server version 10.3.4 and 10.3.5) should be installed to resolve the issue.

Browser cookie values are not setting in IE10 and IE11

Browser cookie values are not setting in IE10 and IE11

While trying to set the cookies in IE10 and IE11 through Java, the values are not stetting in the browser.

The code snippet used to set the cookie is

cookie = new javax.servlet.http.Cookie(cookieHeaderName,"Sample Cookie");

After long struggle we found the issue might be with the value of Expires is not set, IE10 and IE11 expecting the value for Expires and it is not considering the value set in Max-Age.

Fix for the issue - Use the below code to set the cookie value

int expiration = 365*24*60*60;
StringBuilder cookieString = new StringBuilder("TestCookie=Test; ");

DateFormat df = new SimpleDateFormat("EEE, dd-MMM-yyyy HH:mm:ss 'GMT'", Locale.US);
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, expiration);
cookieString.append("Expires=" + df.format(cal.getTime()) + "; ");
//cookieString.append("Domain="+request.getServerName()+"; ");
cookieString.append("Version=0; ");
cookieString.append("Path=/; ");
cookieString.append("Max-Age=" + expiration + "; ");
response.addHeader("Set-Cookie", cookieString.toString());
