This already works a charme when I let hibernate create my database directly by configuring the hibernate.hbm2ddl.auto in the persistence.xml. But I also need those ddl statements in a file. Surprisingly there is no simple property to add to the persistence.xml like there is for EclipseLink. Searching for the simplest solution to get this done I installed hibernate tools for Eclipse (using the update site). But right after restarting Eclipse it is complaining about a class that it can not find: java.lang.NoClassDefFoundError: org/jboss/tools/common/java/IJavaMemberReference This is the first of a series of errors that come up. (I think the other ones are susequent to this first one.) The message in eclipse is: Problems occurred when invoking code from plug-in: "org.eclipse.core.resources". Attached is the complete Stacktrace in a text file. Does anyone have a hint for me what could be wrong or what I could check? Googling for this error or for the class IJavaMemberReference did not reveal much. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/742347#742347] Start a new discussion in JBoss Tools at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
