The package javax.xml.parsers is =
accessible from more than one module
The package org.xml.sax is accessible from more than one module: =
<unnamed>, =
java.xml

As a workaround = for this, you can set your Eclipse Java target version to 8.

Your problem is caused = by using a target version >=3D 9, which enables JDK modularization = (aka Project Jigsaw) AND using some XML functionality being present in = module java.xml (from JDK) and <unnamed> (probably the JavaXML = framework).

I've been struggling with the same = problem.

IMO = to properly solve this in Wonder, JavaXML should never be enabled = as a transitive dependency by any framework using it. = I.e. removing its exported=3D"true" from = the .classpath file.

But maybe there is a better = solution for this?

Best regards,

Hi Ted

I recently = ported my maven webobjects project to Java 11 on MacOS Mojave. I was getting a similar error to yours and so I excluded JavaXML in my pom.xml. I am not sure the solution in fluffy = bunny.

    =
<webobjects.groupId>com.webobjects</webobjects.groupId>
    <webobjects.version>5.4.3</webobjects.version>   =20
    <wonder.core.groupId>wonder.core</wonder.core.groupId>
    <wonder.version>7.2</wonder.version>
...

          =

          =

        </exclusion>
      </exclusions>
    </dependency>

At Hugi's suggestion I added back in Xerces which will also have been excluded by exclduing = JavaXML

<dependency>
	<groupId>xerces</groupId>
	<artifactId>xercesImpl</artifactId>
	<version>2.12.1</version>
	<scope>runtime</scope>
</dependency>

Hope this helps

It sounds like you need to sync up the Wonder build with your local =

I have installed WO, Java, Wonder 7.3.

Almost there, there are some compile errors with wonder. For instance  =
ERPDFGeneration has multiple errors:

The package javax.xml.parsers is accessible from more than one module
The package org.xml.sax is accessible from more than one module: =
<unnamed>, java.xml

What do I need to do to fix this?
