Issues with BIRT classloader ---------------------------- Key: JBIDE-4369 URL: https://jira.jboss.org/jira/browse/JBIDE-4369 Project: Tools (JBoss Tools) Issue Type: Bug Components: birt, UpStream Affects Versions: 3.0.0.GA Reporter: Snjezana Peco Assignee: Snjezana Peco Steps to reproduce: 1) create a new Seam Web Project with the "BIRT Reporting Runtime Component" facet 2) call "Generates Seam Entities" and create some entities 3) create a BIRT report 4) restart Eclipse 5) add JBoss Hibernate Data Source and click Test Connection You will get the "Could not create JPA based Configuration" error (Problem 1). Attached is log1.txt If you build a session factory using the Hibernate Configuration view in the Hibernate perspective, you will be able to create a data source (5) and data set(6) 6) create Hibernate Data Set 7) call the Previews Result tab in the Edit Data Set dialog 8) call "Generate Seam Entities" and click "Refresh" on the second page of the wizard You will get the "<Couldn't connect to Database>" error (Problem 2). 9) try to open *.xhtml file using the VPE editor You will get an error (attached log2.txt). Sometimes Eclipse freezes (Problem 3). There are two issues related to the BIRT engine: - https://bugs.eclipse.org/bugs/show_bug.cgi?id=258574 I have created a patch for this issue. - an issue in DataSetEditor.ItemModelHandler. BIRT sets a context classloader in this class, but doesn't revert the old context classloader. The issue exists in BIRT 2.3.1 and BIRT 2.5.0M7. It is fixed in the current CVS. BIRT creates a classloader using libraries from all the projects in the workspace including thirdparty-all.jar from the *-test project that contains an incompatible xerces version (which causes problems 2 and 3). The BIRT classloader returns the META-INF/persistence.xml file multiple times because multiple instances of the EJB's source folder are in the classpath (which causes problem 1). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
