Java 1.4 and NoClassDefFoundError: org/xml/sax/ext/EntityResolver2

[Domchi]

I'm trying to run spring-ws under Java 1.4.

I've added xalan.jar, xercesImpl.jar, serializer.jar and xml-apis.jar to $JAVAHOME/lib/endorsed as the Xalan/Xerces FAQs say, and that fixed the namespace errors.

However I still get this exception while initializing the context:

org.springframework.beans.factory.BeanDefinitionSt oreException: Unexpected exception parsing XML document from class path resource [context/applicationContext.xml]; nested exception is java.lang.NoClassDefFoundError: org/xml/sax/ext/EntityResolver2

I'm pretty sure that the problem is not with anything I'm doing in my code or configuration, since the same code works in Java 1.5.

I've tried different Xalan/Xerces versions with no success (I'm currently using Xalan 2.7.0 and Xerces 2.9.0). Google said that someone somewhere said that xalan.jar has to be placed into Tomcat's endorsed directory, but this is client application which doesn't use Tomcat.

Any ideas? Is anyone using spring-ws with Java 1.4?

[Arjen Poutsma]

That's weird, because EntityResolver2 should be in xml-apis.jar.

[Domchi]

I cracked it.

The EntityResolver2 is in sax.jar. (Although xml-apis contains the same package.)

And right now I have the following .jars in JRE endorsed folder:
dom.jar
sax.jar
xalan.jar
xercesImpl.jar
xml-apis.jar
jaxp-api.jar

To get dom.jar and sax.jar, I had to download the older JAXP version (1.3.2 instead of 1.4.2) - but I'm using jaxp-api.jar from newer 1.4.2 version. Doesn't make much sense to me but I don't have the time and expertise to investigate further.

Also, to make spring-ws work under Java 1.4, I had to use the older (1.2 instead 1.3) version of SAAJ, since the 1.3 is dependent on Java 1.5. The problem is, SAAJ 1.2 can't be downloaded legally from Sun anymore (or at least I haven't found a way) - in the end I had to Google the filenames and grab it from someone's CVS repository.

Your mileage might vary if you don't use Xerces (and perhaps JDOM).

Arjen, can you please update the spring-ws FAQ regarding Java 1.4?

[Domchi]

Unsecured messages go through as expected, but when I added security, I got the following exception since xws-security has dependancy on JAAS 1.3 (as can be seen on https://maven-repository.dev.java.ne...ty-2.0-FCS.pom).

This is the exception:

So basically JAAS 1.3 doesn't work with Java 1.4, and xws-security doesn't work with JAAS 1.2 which works with Java 1.4.

Which is basically what the spring-ws FAQ says:
"Note that the security module requires Java 5, because an underlying library (XWSS) requires it."

Is there any way to have security on Java 1.4?

[Arjen Poutsma]

Which version of xml-apis do you use? You should use 1.3.0x version, not the 2.0.x version which can be found elsewhere. Contrary to what you might believe, 2.0.x is actually older than 1.3.x.

What I have in my local 1.4.2 endorsed folder:

xalan.jar version 2.7.0
xercesImpl.jar 2.8.1
xml-apis.jar 1.3.04

xml-apis, jaxp-apis and probably dom and sax contain the same classes, so there is no reason to add them all.

We publish SAAJ 1.2 on our maven repo. See http://springframework.svn.sourcefor...saaj-impl/1.2/ and http://springframework.svn.sourcefor...aj-api-1.2.pom.

[Arjen Poutsma]

Is there any way to have security on Java 1.4?

Not yet, but there is http://opensource.atlassian.com/proj...browse/SWS-207. You can vote for it if you want it implemented. (Or better yet: contribute )

[Domchi]

I'm not sure which xml-apis.jar I'm using - from manifest file, it looks like 1.3.1 (?). But it's not the same jar which comes with Xalan and Xerces. If I put only the files you're using in endorsed, I get NAMESPACE_ERR; even with older Xerces version you're using.

[Domchi]

Hm. There is another combination that works but includes Saxon - which is basically what I wanted.

This is the endorsed folder:
serializer.jar
xalan.jar
xercesImpl.jar
xml-apis.jar

All of these files come with Xalan 2.7.0 (which means that Xerces implementation is version 2.7.1!). Serializer.jar is necessary in this combination.

I have the following libraries in classpath:
activation.jar
commons-logging.jar
jaxen-core.jar
jaxen-jdom.jar
jdom.jar
log4j.jar
saaj-api.jar
saaj-impl.jar
saxpath.jar
spring.jar
spring-oxm.jar
spring-ws-core.jar
spring-xml.jar
stax-api.jar
mail.jar (SAAJ 1.2 dependency)
saxon8.jar
dom.jar (from JAXP 1.3)
saxon8-dom.jar

And I set this properties:
System.setProperty("javax.xml.parsers.DocumentBuil derFactory", "org.apache.xerces.jaxp.DocumentBuilderFactoryImpl ");
System.setProperty("javax.xml.parsers.SAXParserFac tory", "org.apache.xerces.jaxp.SAXParserFactoryImpl") ;
System.setProperty("javax.xml.transform.Transforme rFactory", "net.sf.saxon.TransformerFactoryImpl");

Regarding Saxon and DOMResult, which I'm using, and why I'm using dom.jar from JAXP 1.3:
