Subject RE: JVM Crashed because of taglibs
Date Thu, 03 Mar 2005 15:04:12 GMT
Hi Vivek, 

I had similar problems (not with tag libs). You can tell the AIX JVM which parser factories
to use. Just need to set the following options, in the JDK/lib/jre/jaxp.properties file:

javax.xml.transform.TransformerFactory=...
javax.xml.parsers.SAXParserFactory=...
javax.xml.parsers.DocumentBuilderFactory=...

regards,
Vlado

Subject: Re: JVM Crashed because of taglibs

Hi Hen,

today I have done some analysis about the JVM Crash:
1. Jakarta Taglibs are using the Sun XML parser.
2. Now on AIX Machine only IBM Java will run, which in turn will use XML4J
i.e. ibm xml java parser.

Conclusion : So something is happening due to Sun XML parser.

---------------------------------

3. question due to curiosity why Taglibs is not using consolidated xml java
parser.

if can guide something to avoid this JVM Crash please do suggest.
