java.io.StreamCorruptedException
Hi, since i have update to 1.4.7 i found this message in the log files: Error restoring application state: java.io.StreamCorruptedException (InputStream does not contain a serialized object) it occurs only from time to time (e.g. everytime orion is started and the first request comes along). i haven't noticed any problems occuring due to this, but i'm just curious. --nils
EJB arrays as CMP fields
Hi, i'vi been trying to insert an array of EJBs into a CMP field: /** * Links of the article * * @remote-method * @cmp-field */ public abstract Link[] getLink(); /** * Links of the article * * @remote-method * @cmp-field */ public abstract void setLink(Link[] value); (using EJBDoclet :) Link is a CMP. When deploying the jar, i get the following error: ArticleHome_EntityHomeWrapper44.java:603: Undefined variable: context ORList __theList = new Link_ORList45(context); ^ 1 error or is it better to save the EJBs in Colletcions or Enumerations (public abstract Collection getLink();)? Thanks, --nils
Re: orion on unix
Yes, but sudo will still run orion with UID 0. This will not improve security. Then you might as well make a group called 'orion', and put all the users that need access to orion into this group. Change the dir/file perms so that it is read/writable for these users. If you try to get orion to run non-root because of security, follow the example on orionsupport. --nils Scott M.

Problem deploying EJBs using a MySQL data-source
Hi, up to now i always connected to the Hypersonic database. Since i have a mysql database running on another box, i tried to connect to it, using Shailesh Joshi's data-sources.xml and database-schemas/mysql.xml (cf. msg# 05137 Re: Orion and MySQL). This is the errormessage i get when orion tries to deploy my EJBs: Auto-deploying myEJB.jar (No previous deployment found)... Error compiling file:/home/wuzzah/myEJB/myEJB.jar: Error finding a suitable DataSource: jdbc/DefaultCoreDS did not contain a cmt-dataSource/ejb-datasource My data-source: My database-schema: http://www.orionserver.com/dtds/database-schemas.dtd"> any hints? thanks, --nils -- ** * Your mouse has moved.
