Eclipse compiler targetting JDK 1.4

[Marcus Crafter <cr...@fztig938.bank.dresdner.net>]

Hi Troops,

	Hope all is well.
	
	Some people on the users list discovered that the Eclipse Java 
	compiler we're using for XSP is set to target a 1.4 runtime 
	environment, which causes problems when running your application
	under 1.3.
	
	Any thoughts ? should we make the EclipseJavaCompiler class 
	target 1.3 only, or make the class format target configurable, or
	some other option ?
	
	Cheers,
	
	Marcus

Hi Markus,

the problem was realy the compiler settings.
I have changed the compiler setting to Javac. Now all working properly.

At last I can begin to play with SoapServer. :-)

Thanks for Your help,

Alexander

	Could be. The default XSP compiler was changed recently from javac
	to Eclipse.
	
	There's no chance that the XSP pages were compiled with jdk 1.4
	sometime in the past and are left over in your work directory ?
	(it's happened to me :) )

	If not, can you perform your same test using the Javac compiler
	(the settings can be modified in your cocoon.xconf), and report
	back your results ?
	
	Thanks! Cheers,
	
	Marcus

Detect on runtime and configure appropriately? Will work for me.
