Subject problems using j2sdk1.4.0 rc
Date Tue, 12 Feb 2002 11:28:48 GMT
Hi people,
I installed version 1.4.0 release candidate from Sun (under Linux)
but cocoon seems to have problems with this.
I recompiled cocoon-2.1-dev.jar
By calling the first page I got the following error:

ProcessingException: Language Exception ...
Note: has been deprecated...

and other (may be following) errors:
EsqlConnectionCocoon2() is an abstract class. It can not be instantiated. ...

In components/language/programming/javac/
we ask if it is modern (com.sun...) or not (sun...)
But we have only this line (about line 117): compiler = new, "javac");
Here we don't care about modern or not.

I wrote the compile method as follows:
  public boolean compile() throws IOException {
    ByteArrayOutputStream err = new ByteArrayOutputStream();
    boolean result = false;
    if(modern) { compiler = new;
      int iresult = compiler.compile(toStringArray(fillArguments(new ArrayList())));
      if(iresult == 0) result = true;
      else result = false;
    else { compiler = new, "javac");
      result = compiler.compile(toStringArray(fillArguments(new ArrayList())));
      this.errors = new ByteArrayInputStream(err.toByteArray());
    return result;

But now I get a java.lang.IncompatibleClassChangeError

The error log says that Excalibur also has problems:

FATAL_E (2002-02-12) 11:29.05:470   [core    ]
(Unknown-URI) Unknown-thread/LogKitLogger:
Excalibur could not create any connections.
Examine your settings to make sure they are correct.
Make sure you can connect with the same settings on your machine.

Any suggestions?
