      Hello,

      I’m trying to call a java class from a TPS proc used in an UPOC read context like this :

      Code:

      set dispList [cljTPS {MODE $mode} {CONTEXT $ctx} {MSGID NULL} {ARGS {{CLASS testJava}}}]

      But this error occurs :

      Code:

      [pd  :pdtd:ERR /0:       conn_3:10/25/2010 15:49:01] Tcl error:
                    msgId    = none
                    proc       = ‘test’
                    args       = ”
                    result     = ‘java.lang.NullPointerException’
                    errorInfo: ‘
      java.lang.NullPointerException
                    at com.quovadx.cloverleaf.upoc.CloverEnv.processTPS(CloverEnv.java:1268)
         invoked from within
      “processTPS “$instanceMap($__userArgs) $context $mode $mh””
         (procedure “cljTPS” line 41)
         invoked from within
      “cljTPS {MODE $mode} {CONTEXT $ctx} {MSGID NULL} {ARGS {{CLASS testJava}}}”
         (”time” arm line 6)
         invoked from within
      “switch -exact — $mode {
             start {
                 # Perform special init functions
                 # N.B.: there may or may not be a MSGID key in args
      …”
         (procedure “test” line 16)
         invoked from within
      “test {CONTEXT pdupoc_read} {ARGS {}} {MODE time} {VERSION 3.0}”‘

      Does anybody have any idea how to call my java class ?

      Many thanks,

      Aurelien

          Hi Aurelien,

          This isn’t something I’ve ever tried but why are you using mixed code? Can’t you either write it all in Java or in Tcl?

          Regards

          Garry

            Hi Garry,

            It was to call java class in a “if” condition but you’re right I can make this directly in my java class. Good idea.

            Thanks,

            Aurelien
