Nullpointer exception thrown from the StoreDataBean getJspStoreDir method Technote
(troubleshooting)Problem(Abstract) You are using dynacache on WebSphere Application Server 6.0.2 with WebSphere Commerce 5.6.1 or 6.0.0. You see this type of exception:
[2/5/07 0:03:48:414 CST] 0000004b ServletWrappe E SRVE0014E: Uncaught service() exception root cause /ConsumerDirect/include/MiniShopCartDisplay.jsp: java.lang.NullPointerException
at com.ibm.ws.webcontainer.srt.SRTServletRequest.getAttribute(SRTServletRequest.java(Compiled Code))
at com.ibm.ws.cache.servlet.CacheProxyRequest.getAttribute(CacheProxyRequest.java(Compiled Code))
at com.ibm.ws.cache.servlet.CacheProxyRequest.getAttribute(CacheProxyRequest.java(Compiled Code))
at com.ibm.ws.cache.servlet.CacheProxyRequest.getAttribute(CacheProxyRequest.java(Compiled Code))
at com.ibm.commerce.common.beans.StoreDataBean.getJspStoreDir(StoreDataBean.java(Compiled Code))
at sun.reflect.GeneratedMethodAccessor382.invoke(Unknown Source)
The exception may be thrown from a different JSP. However, the exception always originates from the StoreDataBean getJspStoreDir method.
Symptoms of this exception are blank pages being displayed to shoppers. Because the problem is related to dynacache, the problem is intermittent and dependent on traffic to the site.
This problem is likely only to occur if you are using WebSphere Commerce 5.6.1 with WAS 6.0.2 or if you have migrated to WebSphere Commerce 6.0.0 from a previous version of WebSphere Commerce.Resolving the problem Update your cachespec.xml where it contains this section of code:
<!-- Starts Servlet -->
<cache-entry>
<class>servlet</class>
<name>com.ibm.commerce.struts.ECActionServlet.class</name>
<property name="consume-subfragments">true</property>
<property name="save-attributes">false</property>
<property name="store-cookies">false</property>
Add the bolded text as indicated:
<!-- Starts Servlet -->
<cache-entry>
<class>servlet</class>
<name>com.ibm.commerce.struts.ECActionServlet.class</name>
<property name="consume-subfragments">true</property>
<property name="save-attributes">false
<exclude>jspStoreDir</exclude>
</property>
<property name="store-cookies">false</property>
