[jira] Created: (JS2-558) Only "NULL" is shown in browser at what
seems to be random intervals.
Only "NULL" is shown in browser at what seems to be random intervals.
---------------------------------------------------------------------
Key: JS2-558
URL: http://issues.apache.org/jira/browse/JS2-558
Project: Jetspeed 2
Issue Type: Bug
Affects Versions: 2.0-FINAL
Environment: Apache/2.0.52 (CentOS) with Apache Tomcat 5.5.17 running in jdk1.5.0_03. Jetspeed 2.0 Final.
Reporter: Eivinn Hustveit
Priority: Blocker
Everything works fine in the portal most of the time, but at random intervals "NULL" is the only text rendered by the browser. I have looked at the jetspeed.log and found out that it prints out a stacktrace which seems to come from the rendering of the layout portlet. I will try to upload this as an attachement.

-------------------------------------
We have now gotten this error with some more leads. The errror "NULL" came after opening Jetspeed for the first time on that browser session (and that day).
The portlet which fails is as you have mentioned the layout portlet and the fragment "dp-1" is the standard Jetspeed login-portlet.
Hope someone can help.

Attachment: jetspeed_log_snapshot_of_request.txt
This is the exact trace from jetspeed.log for a request through Firefox with the SE K800 UserAgent. It looks to me that it is the line "org.apache.jetspeed.capabilities.impl.CapabilityValveImpl - Mimetype: text/vnd.wap.wml" is the clue to why the portlet fragment dp-1 (VelocityOneColumn) crash with a nullpionter.
I'm currently downloading the Jetspeed source with the tag RELEASE-2.0 and will try to debug it and see whether I can nail it down to some exact reasons. If you have any tips to where I can place my breakpoints please inform me.
PS! Our portal does not serve mobile web-pages, but a normal portlet web-app.

The default profiling rule makes Jetspeed look in the wml directory.
You can change this or create a new rule. In the case of the j2 rule, just remove the mediatype requirement
In the meantime I will try to come up with a patch to the NPE described above
<ProfilingRule id="j2" standardRule="true">
<description value="The default profiling rule for users and mediatype minus language and country."/>
<Criteria>
<Criterion name="user">

Eivinn Hustveit commented on JS2-558:
-------------------------------------
I have now found out what happens when we browse Jetspeed with a UserAgent on which the CapabilityValveImpl returns wml as the mediatype.
1. the line that causes the nullpointer is like you pointed out:
absViewPage = jpt.getTemplate(viewPage + "/" + JetspeedPowerTool.LAYOUT_TEMPLATE_TYPE + ".vm",
JetspeedPowerTool.LAYOUT_TEMPLATE_TYPE).getAppRelativePath();
2. The reason is that jpt.getTemplate is in fact returning null.
3. The cause of point 2 is that the JetspeedPowerToolImpl.getTemplate(path, templateType, locator, descriptor) runs the following code in which returns null:
TemplateDescriptor template = locator.locateTemplate(descriptor);
This is due to the fact that the descriptor is using mediaType="wml" which again makes Jetspeed look for a template.vm located at apache-tomcat-5.5.20/webapps/jetspeed/WEB-INF/templates/layout/wml/en/US/layout.vm
This template does not exist.
I must admit that I cannot find out how to disable the WML support in Jetspeed when it is not needed. In my opinion the standard install should also default to XHTML and not HTML, but this is another discussion.

---------------------------------------
Elvinn, I cannot see where there is an exception thrown for a Capabiility failure.
I expected to find something like:
"We were unable to build a capability map for the agent, "+userAgent+
". This might be an indiciation that the capability database has not been correctly initialized."
or
"CapabilityServiceImpl: UserAgentPattern not valid :"
But i see neither of these messages in the logs
I then wrote a unit test to check for SonyEricsson browser, and our regex found it for the agent. The test passed:
userAgent = "SonyEricssonK800i/R1CB Browser/NetFront/3.3 Profile/MIDP-2.0 Configuration/CLDC-1.1";
System.out.println("Find pattern: " + userAgent);
cm = capabilities.getCapabilityMap(userAgent);
assertNotNull("getCapabilityMap is null", cm);
assertTrue("Ericsson", cm.getClient().getName().equals("sonyericsson"));
capabilityMapReport(cm);
So Im not sure if this error is caused by this particular agent

-------------------------------------
Yes, unfortunately we are. I don't know how I can debug it either because it has never happened on my own computer. It looks to be an error reappearing at random intervals. I will be very grateful if you have any suggestions to how we can try to figure out what the problem is.
Just as a note I can tell you that we have had problems in the past with browser caches, but I don not feel confident enough to blame that in this case since it appeared in the first browser session this last time.

Looking at 2.0 final source, line 196 in LayoutPortlet.java:
absViewPage = jpt.getTemplate(viewPage + "/" + JetspeedPowerTool.LAYOUT_TEMPLATE_TYPE + ".vm",
JetspeedPowerTool.LAYOUT_TEMPLATE_TYPE).getAppRelativePath();
One of the parameters in the statement above must be null.
Ensure that:
1. viewPage is not null. viewPage comes from either a preference or init parameter
2. jpt.getTemplate could be returning null. Although in reviewing the code, I don't see how this could happen

-------------------------------------
I think we finally have found out what causes this issue. It is the use of the User-Agent switcher plug-in in Mozilla Firefox. We are developing services for the mobile phone web-browsers and "emulate" this software using this plugin. After setting user-agent to some phone and entering our Jetspeed portal this NULL message comes up. If one switches back to default (UA=Mozilla...) it all works perfectly.
I assume the best fix would be to support all User-Agents and preferably return a default site if no mode exist for the given UA.
