    JSTL/JBoss/JSP error

    jlauman Newbie

      I got the following error when upgrading my app from JSTL 1.0.x to 1.1.x Other that changing the tld and web xml files to the selvlet 2.4/2.0 spec nothing changed. I'm running JBoss 4.0.1RC3 with Tomcat 5.0.28.

      The error is in a custom scheduling tag that uses java.util.Date, java.text.SimpleDateFormat, java.util.Calendar I'm not sure why I'm getting: org.jboss.util.propertyeditor.DateEditor.getValue(DateEditor.java:42)

      I'd appreciate any help on solving this.

      Thanks,

      Jack

          Apparently the new version is using java bean property editors for the string conversion, and jboss installs its own date property editor. This is simply doing the following:

           public Object getValue()
           {
           try
           {
           DateFormat df = DateFormat.getDateInstance();
           return df.parse(getAsText());
           }
           catch (ParseException e)
           {
           throw new NestedRuntimeException(e);
           }
           }
          


          This is using the locale default format parser, which is not very flexible. You can use the properties-service.xml PropertyEditorManagerService to

           <mbean code="org.jboss.varia.property.PropertyEditorManagerService"
           name="jboss:type=Service,name=PropertyEditorManager">
          
           <!--
           | Register and editor for each of the type_name=editor_type_name listed
           | in properties file style convetion.
           -->
           <attribute name="Editors">
           java.util.Date=my.project.editors.DateEditor
           </attribute>
          
           </mbean>
          


          Presumably there is a DateEditor in the jstl release that should be used.

            Scott:

            Thanks for your reply. The exception is coming from a custom tag library that I use for scheduling. This code works fine in v3.2.7 but not in v4.0.1. I tried several different combinations in the 'properties-service.xml' file, all of which generated mbean errors.

            I don't have a clue as to what should be used here. Is the a way to disable the default date parser?

            Any help would be appreciated.

            Thanks,

              This is show stopper. Does anyone know how to fix this problem? It apparently only affects v4.0.x.

              It seems to affect any call to java.util.Date in a jsp page.

                Create a bug report on jira with the custom tag lib example.

                  For anyone interested here's what I did to solve the JBoss problem with the PropertiesEditor error.

                  I edited org.jboss.util.propertyeditorDateEditor.java and
                  recompiled it wth the following changes and the problem went
                  away. I tried creating a date/time editor and a BeanInfo
                  class but sometimes they loaded and somtime they didn't. It
                  was very sporatic. Changing the JBoss file that was complaining
                  was easier but not a long term fix.

                  Thanks,

                    Jack - great news that you got this fixed...
                    So - the only way around this right now is to recompile JBoss?
                    Did I read correctly thatmodifying the properties file is NON effective?
                    Also - any way you can saved me time and send me the new .class or .jar file I need? Would be really helpful.

                    Thanks so much.

                      Actually - DateEditor.java is not long.
                      can you just paste the new code in and I will compile.

                          The DateEditor has been updated to accept more date formats for the 3.2.7 and 4.0.2 releases.

                          I still need a bug report that has an illustration of the problem as none of the date based jstl examples gave me any problems.
