[rules-dev] an occasional error, I can never remember the cause... (JavaDialect)

java.lang.NoClassDefFoundError: Could not initialize class org.drools.rule.builder.dialect.java.JavaDialect at org.drools.rule.builder.dialect.java.JavaDialectConfiguration.newDialect(JavaDialectConfiguration.java:65) at org.drools.compiler.PackageBuilderConfiguration.buildDialectRegistry(PackageBuilderConfiguration.java:291) at org.drools.compiler.PackageRegistry.<init>(PackageRegistry.java:24) Do others see this? I am sure I have battled it before, but every time I seem to forget what I did to make it go away (perhaps a different thing each time). Any ideas? -- Michael D Neale home: www.michaelneale.net blog: michaelneale.blogspot.com
