Hello Ted,

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 >= 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="true" from the .classpath file.

But maybe there is a better solution for this?

Best regards,

Stefan

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>    
    <wonder.core.groupId>wonder.core</wonder.core.groupId>
    <wonder.version>7.2</wonder.version>
...

    <dependency>
      <groupId>${wonder.core.groupId}</groupId>
      <artifactId>ERExtensions</artifactId>
      <version>${wonder.version}</version>
      <exclusions>

        <exclusion>
          <groupId>${webobjects.groupId}</groupId>
          <artifactId>JavaXML</artifactId>
        </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

Did you check your JAVA version?

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

I run Big Slur but I also use an old JAVA because I’m late to update and test...

I have a new computer with Big Sur 11.5.2. I am in the process of setting this machine up to do WO.

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?
