Unable to run Java command

Question

We are using Webmethods 8.2 and we are trying to setup the initial databases on the SQL server from a linux box. The command format is,

./dbConfigurator.sh -a create -d sqlserver -c storage -v latest -l jdbc:wm:sqlserver://<sqlserverip>:1433;databaseName=DBNAME" -u DBUSER -p Passwd -au ADMIN -ap Passwd

We are getting the following error. Can someone decipher what the error is for us. We appreciate any help we can get. Thanks!

I just added dbConfigurator.sh and setEnv.sh that file calls. Thank you. — Lego, Jul 23 '13 at 15:55
Actually, the `java` command ran just fine. But you have some sort of muck-up in your classpath. Precisely what is hard to say, though -- NoClassDefFoundError is a terribly vague exception that can be raised in a number of different scenarios, with different basic causes. — Hot Licks, Jul 23 '13 at 16:06
I have the xml-apis.jar file under /opt/softwareag/DB/common/lib/ext/xml-apis.jar. can this be manually added to the CLASSPATH or in my setEnv.sh file I put above? Thanks! — Lego, Jul 23 '13 at 17:26

NoClassDefFoundError in Java comes when Java Virtual Machine is not able to find a particular class at runtime which was available during compile time.

In your particular case JAVA cannot find xml-apis.jar, add it to setEnv.sh like this(find the path and edit)

CLASSPATH="$CLASSPATH:$DCI_HOME/../lib/xml-apis.jar"

java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal

Presumably your classpath misses some library org/w3c/dom/ElementTraversal.

Thanks David. I'm not sure how to search for this class. Presumably the class path has to be added on the setEnv.sh file I just attached? – Lego Jul 23 '13 at 15:55

According to one post, they had this issue:

I had an issue when I tried using version 2.0.2, but found that when I reverted back to version 1.4.01 and everything worked again.

If you're using Maven:
<dependency> 
    <groupId>xml-apis</groupId>
    <artifactId>xml-apis</artifactId>
    <version>1.4.01</version> 
</dependency>

You can also download the necessary library if you simply don't have it:

http://www.jarfinder.com/index.php/java/info/org.w3c.dom.ElementTraversal

reference 1: Eclipse java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal

reference 2: http://www.coderanch.com/t/534171/XML/org-dom-ElementTraversal

First you need to determine whether you're dealing with a missing class, or some class's missing class:

http://javarevisited.blogspot.com/2011/06/noclassdeffounderror-exception-in.html

You've got a java.lang.ClassNotFoundException: org.w3c.dom.ElementTraversal, so you're dealing with a missing class (an easier scenario). You need to see what JAR typically contains org.w3c.dom.ElementTraversal. I like to use http://search.maven.org/, even if you're not using Maven, just because it's a comprehensive index of commonly available Java libraries. To search for a class, use fc:org.w3c.dom.ElementTraversal:

http://search.maven.org/#search%7Cga%7C1%7Cfc%3Aorg.w3c.dom.ElementTraversal

You'll find the 1.401 version of xml-apis among others. It does not seem like any of the common JARs in the search results are in your CLASSPATH, unless they're somewhere inside of $DCI_HOME/../lib/ext/sl53, for instance. You can verify this by putting in a line after #runJava like echo $CLASSPATH and look for any of the JARs listed in the search results above.

If they are not there, you need to put the JAR somewhere on the box and edit setEnv.sh to include it (unless you can put it in $DCI_HOME/../lib/ext/sl53 where it will get picked up automatically).
