Error with 1.4.5 - Null

Hi All,
I'm currently trying to run a piece of software I developed last year, but I'm getting a null pointer exception (show at the end of this post). Last year I was running with Java 1.4, but this year I need to run under Java 5. Does any one have any suggestions on what might be wrong? java.lang.NullPointerException at java.util.HashSet.<init>(Unknown Source) at org.skife.jdbi.Args.setArgument(Args.java:76) at org.skife.jdbi.StaticStatementEnvelope.prepare(StaticStatementEnvelope.java:52) at org.skife.jdbi.StatementCache.findInternal(StatementCache.java:194) at org.skife.jdbi.StatementCache.find(StatementCache.java:145) at org.skife.jdbi.ConnectionHandle.query(ConnectionHandle.java:287) at net.ozgamer.pheno.security.db.DbSecurity.authenticate(DbSecurity.java:127) at net.ozgamer.pheno.fds.pages.Index.onOkClick(Index.java:73) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at net.sf.click.util.ClickUtils.invokeListener(ClickUtils.java:539) at net.sf.click.control.Field.invokeListener(Field.java:794) at net.sf.click.control.Submit.onProcess(Submit.java:172) at net.sf.click.control.Form.onProcess(Form.java:1445) at net.sf.click.ClickServlet.processPage(ClickServlet.java:457) at net.sf.click.ClickServlet.handleRequest(ClickServlet.java:332) at net.sf.click.ClickServlet.doPost(ClickServlet.java:275) at javax.servlet.http.HttpServlet.service(HttpServlet.java:710) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at net.ozgamer.pheno.fds.DBIFilter.doFilter(DBIFilter.java:30) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:215) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:210) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:174) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:151) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:870) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:685) at java.lang.Thread.run(Unknown Source) Thanks, |

Looks like it is a problem with some metadata detection magic. I have a fix which I am testing now.
Once you switch to 1.5, I strongly recommend switching to the 2.0 line (which looks like it is stable enough now to get a 2.0 final release when I get a chance), though it is not straightforward as it could be as 2.0 is not API compatible with 1.4 (hence the version number bump). 1.4.6 should appear shortly... -Brian On Apr 18, 2007, at 2:50 PM, Doychi wrote: Brian McCallister said the following on 19/04/2007 7:24 AM:Do you have the code that lead to the error?Yep, the code is below.

I'll do that tonight after work. I would but I'm after path of least resistance as we were trying to re-write the application but failed to do so before the convention. What sort of effort would you expect to make the transition from 1.4 to 2.0? |
