java.lang.NoSuchMethodError while starting PSI Probe

[Meik Behnfeldt]

Hello,

I was able to deploy the probe.war (version 2.2.3) to my tomcat server
(Red Hat Linux 4.1.2-48, Tomcat 6.0.24, JDK 1.6.0.23).

When I start PSI Probe, I get the following stacktrace:

java.lang.NoSuchMethodError:

ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;

Does anybody have an idea how to fix this?

Thanks in advance!

It could be a problem with the pre-compiled JSPs that are included in the probe.war.  They are safe to delete, so try this:

1. Open up probe.war in your favorite ZIP program.
2. Dig down into WEB-INF/classes and delete the jsp directory.
3. Redeploy the modified probe.war file.
   

Let me know how it works out.  These files will be excluded from probe.war in the next release.

[Mark]

Sorry, I forgot one step.  After deleting the jsp directory, you also need to edit web.xml and delete lines 66 to 842.

[Meik Behnfeldt]

Hello Mark,

thanks for your answer.

I just followed the steps you described and the
java.lang.NoSuchMethodError disappeared, but know I get the following
exception:

--

Can I send you a snapshot build to try?  Please email me.

[Mark]

The snapshot build I sent you should have all the JSP mess cleaned up.  It also contains Tomcat 7 support.

Here's what's interesting to me.  The first error and the second error are really the same error...

• java.lang.NoSuchMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext; 
  

• The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory
  

One is a runtime error, and the other is a compile-time error (when it's compiling the JSP).  It may be an issue with your Tomcat, but let's see how that snapshot build works.

Hello Mark,

I have just tested your snapshot build and still get the same error:

Maybe it is really an issue with my Tomcat server (version 6.0.24 as i
wrote initially; I do not have the problem with a locally installed
6.0.29 Tomcat).

Regards

Meik Behnfeldt

[Mark]

That's possible, although I didn't see anything in Tomcat's changelogs to suggest an error.  Did you make any changes to your 6.0.24 installation of Tomcat, like installing a new JSP library?

[Meik Behnfeldt]

Hello Mark,

the relevant Tomcat server was set up by our administration team (copy
of another Tomcat server).

PSI Probe did not work there because of a library in the lib directory
which generated a conflict (class JspFactory).

Thanks for your help!

Meik Behnfeldt

Haha, rockin'.  Happy to help.
