PK37124: APPLICATION ERRORS (404, 500) WHEN ACCESSING PRECOMPILED JSPS

Fixes are available

APAR status

Closed as program error.

Error description

Users Affected:

Customers with WebSphere Application Server at service pack
levels 6.1.0.3 and 6.1.0.5, on distributed systems, who have
precompiled JSPs that use JDK1.5 language features will
encounter this problem.  For example, "enum" is a JDK1.5
language feature that will encounter this problem.
.
This problem does not occur on Z/OS installations.

Problem Symptoms:

For this problem, JSP precompilation completes successfully,
however the JSP pages cannot be loaded because their associated
JSP classes cannot be found when attempting to load the JSP
page.

This problem results in an HTTP error code 404 when attempting
to access the JSP page.  For example:

Error 404: SRVE0203E: Servlet [/jdkLevel15.jsp]:
org.apache.jsp._jdkLevel15 was found, but is missing another
required
class.

This problem also results in exceptions in the server logs:

[11/18/06 13:00:33:473 EST] 0000001d ServletWrappe E
  [Servlet Error]-[_dontKeepGeneratedClassfiles.class]:
  java.lang.ClassNotFoundException:
_dontKeepGeneratedClassfiles.class
  at com.ibm.ws.classloader.CompoundClassLoader.findClass
    (CompoundClassLoader.java:472)
  at com.ibm.ws.classloader.CompoundClassLoader.loadClass
    (CompoundClassLoader.java:373)

    _loadClass(JSPExtensionClassLoader.java:128)
  at com.ibm.ws.jsp.webcontainerext.JSPExtensionClassLoader.
    loadClass(JSPExtensionClassLoader.java:67)
  ... additional lines omitted ...

Problem Resolution:

This problem may be avoided by precompiling only those JSPs that
have JDK1.4 and earlier language features, or by not
precompiling JSP that have JDK1.5 language features.

The recommended solution for this problem is to install the ifix
"6.1.0.3-WS-WAS-IFPKPK37124.pak".  The ifix is applicable to
WebSphere Application Server service levels 6.1.0.3 and 6.1.0.5.
The fix is integrated in the WebSphere Application Server at
service level 6.1.0.7.

The fix replaces the prerequisite JAR file
"org.eclipse.jdt.core_3.2.1.v_677_R32x.jar" with the earlier
version, "org.eclipse.jdt.core_3.2.0.v_671.jar", which does not
have the problem.  The fix also removes the earlier version of
the prerequisite JAR, "org.eclipse.jdt.core_3.1.2.jar", which is
no longer in use.

Important Note:

This APAR PK37124 and associated ifix
"6.1.0.3-WS-WAS-IFPK37124.pak" supercede the prior APAR PK34926
and its associated ifix "6.1.0.3-WS-WAS-IFPKPK34926.pak".  The
ifix for APAR PK34926 corrects the JSP precompilation problem,
but introduces a new problem where the server will fail to start
in "RESTRICTED" mode.  Installation of PK37124 is necessary to
allow server startup in "RESTRICTED" model.  Restricted mode is
enable by setting the server attribute "access to internal
server classes" to "restrict".

With the ifix for PK34926 installed, an attempt to start a
Deployment Manager or an Application Server in restricted mode
will fail with the following error:

ADMU3011E: Server launched but failed initialization.

In addition, the startServer log will contain the following
error:

ADMU3002E: Exception attempting to process server [serverName]
ADMU3007E: Exception
com.ibm.websphere.management.exception.NoServerDefinedException:
No configuration defined for server: [serverName]

There are two possible problems that can be encountered:

1) JSP precompilation completes successfully, however the JSP
pages cannot be loaded because their associated JSP classes
cannot be found when attempting to load the JSP page.

This problem results in an HTTP error code 404 when attempting
to access the JSP page. For example:

Error 404: SRVE0203E: Servlet  /jdkLevel15.jsp : org.apache.jsp.
_jdkLevel15 was found, but is missing another required class.

Problem conclusion

The fix replaces the prerequisite JAR file
"org.eclipse.jdt.core_3.2.1.v_677_R32x.jar" with the earlier
version, "org.eclipse.jdt.core_3.2.0.v_671.jar", which does not
have the problem. The fix also removes the earlier version of
the prerequisite JAR, "org.eclipse.jdt.core_3.1.2.jar", which
is no longer in use.

The fix for this APAR is currently targeted for inclusion
in fixpack 6.1.0.7.
