webMethods Knowlegebase : esapi jar (1796370)

Troubleshooting


Problem

Deploying a web application on v10.3 Application Platform and this web application has some references to org.owasp.esapi.* classes.

It was earlier conveyed that esapi-2.0.1.jar will be provided at run time by Application Platform so have not added any esapi jar into the web application libs folder.

However, now getting 'class not found exception' for esapi classes as shown below:

"java.lang.ClassNotFoundException: org.owasp.esapi.errors.ValidationException

at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1291)

at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1119)"

If esapi-2.0.1.jar is included then get the following exception:

"Classcast Exception:

java.lang.ClassCastException: org.apache.log4j.Logger

incompatible with org.owasp.esapi.Logger"
