Can't figure out why the Printer autogenerated files are not compiling

caos1234 · May 2007

Hello, I'm just starting with ice, but I have an issue compiling the sample Printer.ice file after I use slice2java which works fine.

I'm doing the following:

$ slice2java Printer.ice --output-dir=generated

where Printer.ice is:

module Demo {
    interface Printer {
        void printString(string s);
    };
};

after that I compile using the following line:

javac -d classes -classpath classes:/usr/share/java/Ice.jar -source 1.4 generated/Demo/*.java

So i'm just compiling the autogenerated files (no files made by me)
And I get the following 9 errors:

Weirdly, i had no problem compiling the C++ example.
Any ideas? if you need any more information please reply. Thanks

Hi Carlos,

Welcome to the forum!

I tried to reproduce your errors on Linux with Ice 3.2.0 and Java5, but everything worked fine. You have verified that /usr/share/java/Ice.jar actually exists and has the necessary permission settings?

If you're still having trouble, please provide a detailed description of your environment (OS version, Ice version, Java version, etc.).

Take care,
- Mark

i'm using java 1.4
javac : /usr/lib/j2se/1.4/bin/javac

(java -version)
java version "1.4.2-02"
Java(TM) 2 Runtime Environment, Standard Edition (build Blackdown-1.4.2-02)
Java HotSpot(TM) Client VM (build Blackdown-1.4.2-02, mixed mode)

Ice.jar exists. I've chmoded it to 777 and it still happens
If i don't use Ice.jar as a classpath, I get about 71 errors (cause it doesn't find Ice objects)

ice:3.1.0
ubuntu edgy (i know 3.2 is not supported, so i donwloaded the latest supported version from ubuntu's repositories using apt-get)

Really hope you can help me, cause i'm stuck.

Thanks!

Hi,

I suspect that the Ice.jar file you are using is from an older (pre-3.1.0) version of Ice, since the LocalExceptionWrapper and ice_facet symbols were added in Ice 3.1.0. You can verify the Ice version of a translator by running

$ slice2java -v

To verify the version of Ice.jar, compile and run the following program:

public class IceVersion
{
    public static void main(String[] args)
    {
        System.out.println(IceUtil.Version.ICE_STRING_VERSION);
    }
}

Hope that helps,
- Mark

One step to go

You were right. The Ice.jar version is 3.0.1
Could you help me with where I could download a 3.1.0 version of Ice.jar?
I appreciate it a lot.
Thanks

I'm not sure how things are structured in the Ice packages for Ubuntu, but on Fedora and RHEL you would need to install the ice-java and ice-java-devel RPMs. If you can't find the correct package, you can download this file:

IceJ-3.1.0-java2.tar.gz

Take care,
