RE: AS/400 and Java (Tomcat on AS400) -- JAVA400-L

Mark,
I had an applet that was using only JDK 1.4 & higher version of TomCat and so I 
only downloaded the jaws and xalan200 & xerces.jars.  I then created a folder 
and copied them to this folder and changed the entries in the 
workers.properties as :

# worker.jni.class_path=/QIBM/ProdData/Connect110/classes/xerces311.jar
worker.jni.class_path=/QIBM/ProdData/Connect110/classes/xalan200.jar
# worker.jni.class_path=/QIBM/ProdData/HTTPA/admin/pgm/xerces.jar
worker.jni.class_path=/home/Sudha/xerces.jar
# worker.jni.class_path=/QIBM/ProdData/java400/jdk12/lib/tools.jar
worker.jni.class_path=/home/Sudha/jaws.jar
# worker.jni.jvm_lib=/QIBM/ProdData/java400/jdk12/lib/rt.jar
worker.jni.jvm_lib=/home/Sudha/rt.jar

I left the rest as the same.

In the httpd.conf  I have entries for TomCat as which you might already have :
#
LoadModule jk_module /QSYS.LIB/QHTTPSVR.LIB/QZTCJK.SRVPGM
JkWorkersFile /www/sudhaa/conf/workers.properties
JkLogFile /www/sudhaa/logs/jk.log
JkLogLevel error
#
# in-process directives
#
JkMount /servlet/*  jni
JkMount /jsp/*.jsp  jni

Now when I start my http, TomCat starts and my applet runs.

Perhaps this could be of help to you.

Thanks,
Sudha

David,

Gave this a try this AM and it did not work.  The server will not start
with the XML parser JAR files moved from common/endorsed to the server/lib
folder.  I receive the following error immediately on startup.

Exception during startup processing
java.lang.reflect.InvocationTargetException:
javax.xml.parsers.FactoryConfigurationError: Provider
org.apache.xerces.jaxp.SAXParserFactoryImpl not found
        at
javax.xml.parsers.SAXParserFactory.newInstance(SAXParserFactory.java:141)
        at
org.apache.commons.digester.Digester.getFactory(Digester.java:511)

At this point it is starting to look like my best bet will be waiting for
the next version of jtopen unless you think an older rev of Tomcat might
work better?

Thanks

Mark

Mark

Did you try moving the xercesImpl and xml-apis jar files out of
common/endorsed/lib to
server/lib? That should make them invisible to your apps. Does this
happen on a
windows based machine also? I can't remember the exact circumstances
but I have
seen the verify error in other cases. I believe it was when compiling
with the 1.4 JDK
with a 1.3 target and deploying to the 400. In that case, compiling
with the 1.3 JDK
fixed the problem.

David,

With x4j400.jar in my webapp/lib folder I get this error:

java.lang.VerifyError: (class: com/ibm/as400/data/PcmlSAXParser,
method:
signature: (Ljava/lang/String;Ljava/lang/ClassLoader;)V) Incompatible
object argument for function call
        at
com.ibm.as400.data.ProgramCallDocument.loadSourcePcmlDocument(ProgramCallDocument.java:1044)
        at
com.ibm.as400.data.ProgramCallDocument.loadPcmlDocument(ProgramCallDocument.java:949)
        at
com.ibm.as400.data.ProgramCallDocument.(ProgramCallDocument.java:97)

Which I assume has to do with Xerces issues.

If nothing else, apparently it is the next version of jtopen (3.3) due
in
a week or so that is supposed to change it to work with newer parsers.
Hopefully that will resolve it.

Mark
