Missing MDE4UML plug-in org.apache.xerces for Eclipse

Former Member

Hello,

I have the following problem that I would really appreciate some help with.

Background

1. I have set up Eclipse 3.0.2

2. I downloaded MDE4UML 3.1.3 (namely file mde-studio-eclipse-3.0-plugin-3.1.3.zip) from m1global.org

3. Everything seems to be working ok (although I havent done much work within MDE).

Problem

When I try to obtain or update software using Help > Software Updates > Find and Install > Search for new features to install, and select any new feature, the following error message is detailed

Model-driven Development Environment Studio (3.1.3) requires plug-in "org.apache.xerces".

What is the solution to this problem? I could comment out the following line in the feature.xml file for this plugin

<import plugin="org.apache.xerces"/>

but I'm not sure if it is the right thing to do.

Thanks for the help in advance.

Hi,

I think you need to check the plugin folder of the eclipse so that it contains the folder "org.apache.xerces_<version>".

This is the API plugin is for XML processing.

if you don't find it than create a folder with name "org.apache.xerces_<version>" in the plugin directory. and then add <b>xmlParserAPIs.jar,xercesImpl.jar</b> to this folder and the create two files with following contains in the same folder.

<b>plugin.xml</b>

<i><?xml version="1.0" encoding="UTF-8"?>

<plugin

name="%pluginName"

id="org.apache.xerces"

version="4.0.13"

provider-name="%providerName">

<!-- This is an IBM maintenance branch of xerces 2.0.0 -->

<runtime>

<library name="xmlParserAPIs.jar">

<export name="*"/>

<packages prefixes="javax.xml,org.w3c.dom,org.xml.sax"/>

</library>

<library name="xercesImpl.jar">

<export name="*"/>

<packages prefixes="org.apache,org.w3c.dom"/>

</library>

</runtime>

</plugin></i>

<b>plugin.properties</b>

<i>pluginName = Xerces Based XML Parser

providerName = Eclipse.org</i>

you will get the jar files at apache's site

Many thanks for the response.

I've done exactly as you responded word to word and restarted Eclipse but the problem persists.

Any ideas?

Thanks
