Eclipse with ibm-jdk

[Massimo B.]

Hello.

I emerged ibm-sdk-bin-1.4.2 and eclipse-sdk on a PPC.

But doing the tutorial for "hello world" give an error:

Code: Select all

Activation.main: warning: sun.rmi.activation.execPolicy system
property unspecified and no ExecPermissions/ExecOptionPermissions
granted; subsequent activation attempts may fail due to unsuccessful
ExecPermission/ExecOptionPermission permission checks.  For
documentation on how to configure rmid security, refer to:

http://java.sun.com/j2se/1.4/docs/tooldocs/solaris/rmid.html
http://java.sun.com/j2se/1.4/docs/tooldocs/win32/rmid.html

Activation.main: an exception occurred: Port already in use: 1098; nested exception is:
        java.net.BindException: Address already in use
java.rmi.server.ExportException: Port already in use: 1098; nested exception is:
        java.net.BindException: Address already in use
        at sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:283)

Beside the error messages, Eclipse has produced bytecode in the workspace.
I can run this code by

Code: Select all

java Hello

so jdk should be installed right.
The same error I get, if I do

Code: Select all

rmid -J-Djava.security.policy=rmid.policy

as described in the URLs, but they relate to SUNs jdk.
IBM-jdk is the only available for PPC.

Do I have to configure Eclipse?

What is the output of "java-config -L"? I just guess that your default java vm is "blackdown JDK", which is really not work well with eclipse. The ibm-jdk works well with eclipse on my machine.

[Massimo B.]

Code: Select all

# java-config -L
[ibm-jdk-bin-1.4.2] "IBM JDK 1.4.2" (/etc/env.d/java/20ibm-jdk-bin-1.4.2) *
[ibm-jre-bin-1.4.2] "IBM JRE 1.4.2" (/etc/env.d/java/20ibm-jre-bin-1.4.2)

I also tried the JRE, which should not be needed with JDK.
Can you tell me, how you configured eclipse to work with the ibm-jdk? It should not be caused by the PPC?

Project properties > java build path > libraries (add library)? I use sun, by the way, and it's as smooth as java can be.

[ibm-jre-bin-1.4.2] "IBM JRE 1.4.2" (/etc/env.d/java/20ibm-jre-bin-1.4.2)

IMHO, it should work just fine, and should not be caused by the PPC! I think, you should take a look closely on how the RMI works, and how to set it up. From the error message, seem to me that it is an RMI issue not the eclipse. The "core java 2 : volume II" book has a chapter for this topic. Hope it help.

Edit: I run eclipse on PC with IBM JDK.

Thanks, it works.
There was only "hello world" enabled, "JRE System Library" was disabled. After selecting both it worked. What I don't understand: Now it is not selected anymore, but "Run as Java application" still works.
So I go on learning Java.

You've added it to your project. You probably have access to the library from the panel on your left. The rest is magic.
