websphere

问题 My webapp is part of a larger EAR that is deployed into a websphere server. The server hosts number of other apps on the same virtual server. My webapp has some initialisation/health checks in a servletContextListener->contextInitialized method. I want to make the webapp unavailable if initialisation/health checks fail. What is a realiable way of doing this? Will throwing a RuntimeException from within contextInitialized suffice? Is the rest of the EAR still expected to be available? Thank

问题 I am embedding JRuby on a JAR file and it's being used by a EAR file that I am deploying to WebSphere. When I call the class from my workspace, it works fine, however when I call it inside WebSphere, here's what I get: [3/31/11 11:21:15:984 BRT] 00000042 SystemErr R classpath:/lib/xmlcompare.rb:4:in `require': no such file to load -- rubygems (LoadError) from classpath:/lib/xmlcompare.rb:4 from classpath:/lib/xmlcompare.rb:1:in `require' from <script>:1 After some research, I noticed that

问题 I'm using WebSphere 7 and their JPA 2.0 implementation which is based on OpenJPA, and I have something driving me crazy. I have to connect to a SQL Server 2008 database that uses the database column encryption. The encryption is done by several database commands: 1 - OPEN SYMMETRIC KEY DECRYPTION BY CERTIFICATION 2 - Perform insert/select/update/etc using the database methods EncryptByKey or DecryptByKey 3 - CLOSE SYMMETRIC KEY I have searched and it does not appear that OpenJPA supports this

问题 I am getting a java.lang.IncompatibleClassChangeError with the following snippet: Workbook workbook = new HSSFWorkbook(); Font arial = workbook.createFont(); // java.lang.IncompatibleClassChangeError thrown here I am using POI 3.7 with WebSphere 7 Portal Server.

The project also uses JasperReports 4.1.2. Can I provide more

问题 Hi i have a really strange problem. I work on a project that uses Spring 4.2.4 , Hibernate 5 and WebSphere Liberty Profile 8.5.5 as application server. When i change the content of jsp files, this changes are not reflected and i have to restart the server every time. Instead changes made to css or java files are reflected and i do not need to restart the server. I created a little project with only one jsp and the spring libraries to isolate the problem and i noticed that if i remove the
