Hi
We've added initial support for Java 1.5 compilation: the JDT compiler
jar has been upgraded to 3.1.1 and JR or system properties specify
whether 1.5 compilation should be perfomed (as suggested by Havier).
There is a sample that shows how 1.5 compilation can be used.
To be noted that some things (like generic types for
parameters/variables) are not yet supported.

Lucian Chirita

Thanks again for replying.
It works only when i use the 3 parameters related to jdk version :
settings.put(CompilerOptions.OPTION_Compliance,
CompilerOptions.VERSION_1_5);
settings.put(CompilerOptions.OPTION_Source, CompilerOptions.VERSION_1_5);
settings.put(CompilerOptions.OPTION_TargetPlatform,
CompilerOptions.VERSION_1_5);
But for more usability (working with system properties), I made this patch to
JRJdtCompiler at line 301 :
Enumeration systemPropertiesName =
System.getProperties().propertyNames();
while (systemPropertiesName.hasMoreElements())
{
String systemPropertyName = (String)
systemPropertiesName.nextElement();
String systemPropertyValue = (String)
System.getProperties().get(systemPropertyName);
if ( systemPropertyName.startsWith("org.eclipse.jdt.core.compiler")
&&
systemPropertyValue != null && systemPropertyValue.length() > 0)
{
log.info("Adding system property \"" + systemPropertyName +
"\" with value \"" + systemPropertyValue + "\" to compiler
settings map");
settings.put(systemPropertyName,systemPropertyValue);
}
}
Is-it possible to make similar functionality in future release?
Of course, only if the community think it could be useful and it was not done
yet. ;-)
Regards,
Xavier Frisaye

You can also set
settings.put(CompilerOptions.OPTION_TargetPlatform,
CompilerOptions.VERSION_1_5);
if you want 1.5 class files generated..

Hi
If you want to use 1.5 code in your report, you'll have to set the
following option when compiling the report (in JRJdtCompiler.java):
settings.put(CompilerOptions.OPTION_Source,
CompilerOptions.VERSION_1_5);

Thanks a lot for your reply.
Your patch seems to work but i'm encountering another problem, i have
the same auto-boxing compilation error than with the non 3.1
jdt-compiler :
Caused by: net.sf.jasperreports.engine.JRException: Errors were
encountered when compiling report expressions class file:
1. Cannot cast from boolean to Boolean
value = (java.lang.Boolean)(true);
<----------------------->
2. Cannot cast from boolean to Boolean
value = (java.lang.Boolean)(true);
<----------------------->
3. Cannot cast from boolean to Boolean
value = (java.lang.Boolean)(true);
<----------------------->
3 errors
Is there a way (sys property or any) to activate Java 1.5 compilation
in Jdt-Compiler?
Best regards,
Xavier

Hi Xavier
The following patch ensures support for the 3.1 Jdt compiler:
http://sourceforge.net/tracker/index.php?func=detail&aid=1233072&group_id=36382&atid=416705
JRJdtCompiler rev 1.12 supports both the 3.1 compiler and the one
distributed with JasperReports. This is part of the 1.0.0 release.
If upgrading to 1.0.* is not an option, you could apply the patch to
the 0.6.7 sources and use the 3.1 compiler.
HTH,
Lucian

Hi all,
I'm using Jasper Reports 0.6.7 with Java 1.5 and JavaC for template
compilation .
But i would try to use jdt compiler instead of JavaC but it doesn't
work with Java 1.5 (autoboxing compilation error).
I also try the lastest jdt compiler from Eclipse (3.1.0) but it
seems its api has changed and it is no more compatible with Jasper
0.6.7.
Am i missing something?
Does anyone have this problem?

Xavier Frisaye
