Tomcat cannot find gdk_custom.jar, Oracle cannot create it?
Starting Tomcat 8, I get a warning:
02-Aug-2017 11:14:21.363 WARNING [RMI TCP Connection(5)-127.0.0.1]
org.apache.tomcat.util.scan.StandardJarScanner.scan
Failed to scan
[file:/C:/Users/543829657/HomeTomcat/tomcat/lib/gdk_custom.jar] from
classloader hierarchy java.io.FileNotFoundException:
C:\Users\543829657\HomeTomcat\tomcat\lib\gdk_custom.jar
(The system cannot find the file specified)
All the answers I've found are advice for creating an gdk_custom.jar
Oracle file ginstall
. I've limited my google search to the last two years and the answers are here :
java -classpath $ORACLE_HOME/jlib/orai18n.jar:$ORACLE_HOME/lib/xmlparserv2.jar ginstall -add <Name of NLT file>
But by running the line:
>java -classpath c:/Oracle/jlib/orai18n.jar:c:/Oracle/lib/xmlparserv2.jar ginstall -add lx2dddd.nlt
displays the message:
Error: Could not find or load main class ginstall
I looked over orai18n.jar
. In fact, it is not in it ginstall
! ginstall
located in orai18n-tools.jar
.
>java -classpath orai18n-tools.jar Ginstall -add lx2dddd.nlt
Usage: Ginstall [-dOutputDir] <NLT file> ...
-d: indicates the directory where the output file is written to
do not specify 'd' for UDC, a zip file gdk_custom.zip will be
written to the current directory
Ok, the text in the Oracle docs is outdated, it seems.
>java -classpath orai18n-tools.jar Ginstall -d. lx2dddd.nlt
Now it goes further but fails again:
Exception in thread "main"

Maybe this parser was needed? But
>java -cp orai18n-tools.jar;c:/Oracle/lib/xmlparserv2.jar Ginstall -d. lx2dddd.nlt
has the same result.
And it is not generated gdk_custom.jar
(or zip) ....
What's interesting, according to http://www.findjar.com/jar/com.oracle/oc4j/11/jars/xmlparserv2.jar.html?all=true , xmlparserv2.jar should contain the DOMParser class.
How can I get this one gdk_custom.jar
?

We don't need to create gdk_custom.jar
.
All we need is to prevent Tomcat from looking for it. As Tomcat 8.0.38
it scans by default . We need to disable scanning. This way, you won't see many excessive warnings, and the server starts up faster.
add the following line to tomcat/conf/context.xml
:
<Context>
...
<JarScanner scanManifest="false"/>
</Context>
