error when using xdoclet

[Matthew Phillips]

When I try to use xdoclet to generate a web.xml file I receive the following error:
java.lang.NoClassDefFoundError: org/apache/log4j/Category
at xdoclet.util.Log.getCategory(Log.java:22)

My target appears as follows:

 <target name="webxml" depends="compile" >
    <taskdef name="webdoclet" classname="xdoclet.web.WebDocletTask" classpath="${xdoclet.jar.path};${log4j.jar.path};${ant.jar.path}" />
    
    <webdoclet destdir="webapp" force="${xdoclet.force}" >
        <fileset dir="${src}" />
        <deploymentdescriptor />
    </webdoclet>
</target> 

My properties are defined as follows:

 <property name="xdoclet.jar.path" value="/java/ant/lib/xdoclet.jar" />
<property name="log4j.jar.path" value="/java/jakarta-log4j-1.2.7/dist/lib/log4j-1.2.7.jar" />
<property name="ant.jar.path" value="/java/ant/lib/ant.jar" /> 

Has anyone seen this issue and know how to resolve it? Thanks.

Try this:

<path id="xdoclet.classpath">
    <pathelement location="${xdoclet.jar.path}"/>
    <pathelement location="${log4j.jar.path}"/>
    <pathelement location="${ant.jar.path}"/>
</path>
<target name="webxml" depends="compile" >
    <taskdef name="webdoclet" classname="xdoclet.web.WebDocletTask" classpath="${xdoclet.classpath}" />
    
    <webdoclet destdir="webapp" force="${xdoclet.force}" >
        <fileset dir="${src}" />
        <deploymentdescriptor />
    </webdoclet>
</target>

That didn't work either. It seems to be finding the other jar files in the classpath. It is just not finding the log4j jar or at the very least that particular class. Thanks for the attempt.

I found a solution. For some reason it didn't like the fact that the log4j jar was not in ant/lib. When I copied it there and pointed my path element to that location it worked. It doesn't seem like the ideal solution, so if anyone see's anything else I am still open to suggestions.

That is actually what I was going to suggest next . Putting the jar in ant/lib has the effect of putting it on Ant's Classpath. That is not ideal but it gets the job done...
Maybe there is something about Ant and taskdefs that I am missing but I think what you had before should have worked.

I have discovered that xdoclet will not look anywhere on the classpath that is not in ant/lib. I had it running, but it would not add the servlet element to web.xml until I copied j2ee.jar to ant/lib. I am using 1.1.2. I am going to try the beta release of 1.2.0 and see if it is any different. I'll keep you posted on my results.

[Matthew Phillips]

Upon further review, it appears that this is the correct way of doing things. I was looking over the samples and some readme files (I know, I should RTFM before posting) and it appears that the required jars need to be copied into the same directory as the xdoclet.jar file.

Hey there,
Do not place anything in the ant installation lib folder
You don't even need to define a classpath to get your job done.
The ideal way in using ant is the following
define your own path ant point it to the location of the class or jar files you want to include. This is an exempt of my build.xml
<property name="xdoclet.lib" value="/opt/java/xdoclet/lib" />
<property name="project.lib" value="${basedir}/lib" />
<path id="classpath">
<!-- include xdoclet jar files -->
<fileset dir="${xdoclet.lib}">
<include name="*.jar" />
</fileset>
<!-- any jar files included in the lib directory
are automatically appended to the classpath -->
<fileset dir="${project.lib.dir}">
<include name="*.jar" />
</fileset>
</path>
