Re: [Opaltoolkit-users] Installation problems

Sriram,

 (Keeping on the list in the hopes that others will benefit.)

Here is the listing of Tomcat¹s directory:

[mi3c@mi3c-jobs apache-tomcat-6.0.29]$ ls webapps/opal2/WEB-INF/lib
activation-1_0_2.jar         javamail-1.4.3.jar
ant-1.7.0.jar                javassist-3.4.GA.jar
antlr-2.7.6.jar              jaxrpc.jar
axis-ant.jar                 jcommon-1.0.12.jar
axis.jar                     jdom-1.1.jar
c3p0-0.9.1.2.jar             jfreechart-1.0.8.jar
cglib-2.1.3.jar              jstl.jar
classad.jar                  jta-1.1.jar
commons-beanutils-1.7.0.jar  mailapi-1_3_1.jar
commons-chain-1.1.jar        mysql-connector-java-5.1.8-bin.jar
commons-cli-2.0.jar          opal-ws-2.3.1.jar
commons-collections-3.1.jar  oro-2.0.8.jar
commons-digester-1.8.jar     postgresql-8.2-506.jdbc3.jar
commons-discovery-0.2.jar    rome-1.0RC1.jar
commons-fileupload-1.2.jar   saaj.jar
commons-io-1.4.jar           slf4j-api-1.5.2.jar
commons-logging-1.0.4.jar    slf4j-log4j12-1.5.2.jar
commons-validator-1.3.1.jar  standard.jar
db2jcc.jar                   struts-core-1.3.8.jar
dom4j-1.6.1.jar              struts-extras-1.3.8.jar
drmaa.jar                    struts-taglib-1.3.8.jar
hibernate3.jar               wsdl4j-1.5.1.jar
hsqldb.jar


It looks like everything is installed (opal-ws-2.3.1.jar).  I did restart
Tomcat a few times.  No errors on install.

Please let me know what I can send to you to help debug this...

Thanks,
-dan
