Known Problems with 1.4 and earlier

JacORB 1.4.1

• IDL compiler

  The IDL compiler does not correctly unwind aliased type names (typedefs) in operation signatures if the alias is used as an out parameter. In this case, wrong holder names are generated in the mapped Javaa classes.

  • Fix: Download idl.jar and copy it to your JacORB/lib directory.

JacORB 1.3.30

• Marshalling:

  Demarshalling arrays of IDL long longs has a bug and always reads 0s.

  • Fix: Download CDRInputStream.java and copy it to src/org/jacorb/orb, then rebuild JacORB.
• IDL compiler:

  For all problems: download a new idl.jar file and place it in your lib directory. Additionally, you may want to download the complete, updated source code for the IDL compiler. The latest compiler version number is 1.3.35 (which is displayed when typing idl -version.

  • Wide string constants not accepted by compiler.
  • Wrong TypeCode marshalling code generated for unions with enum switch type.
  • Problem: out parameter types are not correctly unwound if typedef'ed to a basic type, e.g., string.
    
  • Problem: IDL compiler checks in all enclosing scopes for name clashes of IDL type definitions, not just in the immediately enclosing scope.
    
  • Problem: IDL compiler sometimes generates incorrect names when referring to constants not defined in an interface.
    

JacORB 1.3.21

• IDL compiler:

  For all problems: simply copy the Java file for the fix to src/org/jacorb/idl. Then type ant compiler in the installation directory to rebuild the compiler

  • Uninitialized string members in exceptions and structs. Strings should be initialized to "", otherwise there can be MARSHAL excpetions at runtime because of null values.
    Fix: Member.java
  • Multi-dimensional sequences: generated code does not compile with javac.
    Fix: SequenceType.java
  • Compiler does not complain if oneway operations declare exceptions or return types other than void.
    Fix: OpDecl.java. Note: There is a oneway error in one of our own IDL files. If you apply this patch, the IDL compiler will bail out when compiling idl/jacorb/Tracing.idl. You need to remove the oneway keywords in this file to be able to recompile JacORB successfully.
  • Arrays of anys: generated code does not compile with javac.
    Fix: ArrayTypeSpec.java
• wstring inside Anys: When wstrings are inserted into Anys, the marshalling stream throws a TypeCode.BadKind exception due to a missing entry in the internal TypeCode.length() method.

  Download TypeCode.java and copy it to src/org/jacorb/orb/TypeCode.java. Then type ant in that directory to recompile, and ant libs in the installation directory to rebuild the libraries.

• The NameServer issues a NotFound exception for a server while the server is being restarted by the ImR If the server rebinds itself with the NameServer while it is being started by a lookup request to the NameServer, this exception can occur, due to a bug in the handling of the LocationForward from the ImR.

  Until we are capable of providing a bug fix, please avoid rebinding while the server is being restarted due to a request to the NameServer. Basically it isn't necessary to rebind, because of the ImR the "old" reference that is stored in the NameServer is still valid.

• The trader doesn't start / Compiling the trader misses some classes

  Unfortunately, we forgot to update some trader buildfiles. Download tr_patch.tar.gz, copy it to src/jacorb and gunzip/untar it. After that recompile the trader by typing ant in the trading dir and ant libs in the JacORB root dir.

JacORB 1.3.11

• IDL compiler update: The IDL compiler did generate a few superfluous helper classes, and it did not check rigorously enough for some illegal IDL identifier redefinitions. There were also problems with multiply inherting the same operation name, which is generally illegal but allowed in the case of "diamond" inheritance. Finally, there was a bug in the name resolution algorithm.

  Download idl-1_3_12.zip and unzip the archive in your JacORB installation directory. Then type ant compiler to build the new compiler.

• Missing script file templates jacotemplate1 and jacotemplate1.bat for JDK 1.1.

  Download jacotemplate1 and jacotemplate1.bat and copy them to JacORB1_3_11/bin. Type ant jaco in the installation directory JacORB1_3_11/bin to have ant generate the jaco script for you. In case ant complains that it can't find bin/jaco.bat to begin with (it wants to delete it before generating), just copy one of the template files to bin/jaco.bat.
