Hi, > Are you running "Generate FIX Messages" from Eclipse's external > tool menu? If not, it should be run from there for an Eclipse > build.

Well, I thought I had the latest version since used the Software Update feature. But I guess I should have known that it didn't pick up major releases so I've now upgraded and moved my projects to Eclipse 3.1.2. "Generate FIX Messages" worked just fine with the new version of Eclipse so I've now managed to build my own quickfixj. > I haven't received any reports of the ThreadedSocketInitiator > hanging during construction.

If it is something like > that, please tell me and I'll look into it from the QFJ side. It turned out that the ThreadedSocketInitiator actually threw an exception in the constructor that I managed to throw away without feedback in my application. I've modified my code to trap the exception and this is what I got: quickfix.ConfigError: error during session initialization at quickfix.mina.initiator.AbstractSocketInitiator.createSessions(AbstractSocketInitiator.java:113) at quickfix.mina.initiator.AbstractSocketInitiator.<init>(AbstractSocketInitiator.java:67) at quickfix.mina.initiator.AbstractSocketInitiator.<init>(AbstractSocketInitiator.java:60) at quickfix.ThreadedSocketInitiator.<init>(ThreadedSocketInitiator.java:32) at trader.fix.QuickFIXCommunicator.initializeConnection(QuickFIXCommunicator.java:749) ... 4 more Caused by: java.lang.RuntimeException: java.io.EOFException at quickfix.FileStoreFactory.create(FileStoreFactory.java:65) at quickfix.Session.<init>(Session.java:212) at quickfix.DefaultSessionFactory.create(DefaultSessionFactory.java:125) at quickfix.mina.SessionConnector.createSession(SessionConnector.java:109) at quickfix.mina.initiator.AbstractSocketInitiator.createSessions(AbstractSocketInitiator.java:106) ... 8 more Caused by: java.io.EOFException at java.io.DataInputStream.readInt(DataInputStream.java:358) at quickfix.FileStore.initializeMessageIndex(FileStore.java:172) at quickfix.FileStore.initializeCache(FileStore.java:107) at quickfix.FileStore.initialize(FileStore.java:102) at quickfix.FileStore.<init>(FileStore.java:89) at quickfix.FileStoreFactory.create(FileStoreFactory.java:63) ... 12 more The problem occured when creating the FileStoreFactory. The directory I specified had some old files in it from a previous run with the _jni version. My guess is that the _jni version of the files used different EOF delimiters or something. I haven't looked into the problem in more detail since the solution was very simple, just remove the old files from the directory and everything works just fine. Not sure if this is a bug but it might be a good idea to add in the documentation somewhere.
