I have been trying to create a custom component in LiveCycle ES. So i've been looking at<br />the email sample that is available in LiveCycle ES (LiveCycle_ES_SDK\samples\Foundation\CustomComponents\Email)<br /><br />I have followed the steps i the readme and have successfuly created email.jar<br /><br />Now, when I try to deploy the component: In workbench's Components panel, <br />I right click and click on InstallComponent, and select email.jar.<br />But as it tries to install, it gives an error. This is what the log says:<br /><br />!ENTRY com.adobe.DSC_Admin_UI 4 4 2008-05-06 14:38:18.419<br />!MESSAGE install of C:\Documents and Settings\190536\workspace\email-component\deploy\email.jar failed<br />!STACK 0<br />java.lang.NoClassDefFoundError: com.sun.activation.registries.LogSupport<br /> at javax.activation.MimetypesFileTypeMap.<init>(MimetypesFileTypeMap.java:73)<br /> at javax.activation.FileTypeMap.getDefaultFileTypeMap(FileTypeMap.java:98)<br /> at com.adobe.idp.Document.init(Document.java:455)<br /> at com.adobe.idp.Document.<init>(Document.java:366)<br /> at com.adobe.dsc.views.RegistryTreeViewer$InstallWithProgress.run(RegistryTreeViewer.java:1208)<br /> at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:113)<br /><br />Envt Configuration:<br />Windows XP<br />Jboss Turnkey Installation<br /><br />We also tried deploying other existing components (avoka) but it gives the same error <br /><br />What could be wrong?
