[Biojava-l] Biojava GUI and applets

[Schreiber, Mark]

Hi -
 
This is cause the applet is trying to read AlphabetManager.xml which applets are not generally allowed to do (read files) due to the sand box. I beleive you will need to change your security policy. Not sure on the details but the Sun java site has some documentation.

	Hi,
	
	Thanks Mathew!
	I followed your instructions
	
	I tried
	
	   <APPLET code="BioApplet.class"
	        width="600"
	        height="400"
	        archive="biojava.jar, xerces.jar, bytecode.jar" >
	  </APPLET>
	
	And I put .jar files into the same directory as the applet and html page
	
	But now, errors have changed:
	
	java.security.AccessControlException: access denied
	(java.util.ProperyPermission entityExpansionLimit read)
	...
	rethrown as org.biojava.bio.BioError. Unable to initialize AlphabetManager
	     at
	org.biojava.bio.symbol.AlphabetManager.<clinit>(AlphabetManager.java:896)
	     at.org.biojava.bio.seq.DNATools.<clinit>(DNATools.java:54)
	rethrown as org.biojava.bio.BioError: Unable to initialize DNATools
	     at.org.biojava.bio.seq.DNATools.<clinit>(DNATools.java:85)
	     at.org.biojava.bio.seq.io.SeqIOTools.getDNAParser(SeqIOTools.java:181)
	...
	
	
	
	
	Thanks

	Ah - I think I see potential problems. Firstly, you should have just one
	archive attribute with a list of archives seperated by spaces and
	optional white-space. Secondly, you are using file locations for the
	jars - they need to be URLs that are relative to your html page that
	contains the applet. So - try something more like this:
	
	
	
	and put the three jar files in the same directory as your applet and the
	html page.
