<br><font size=2 face="sans-serif">Hi Mark,</font>
<br>
<br><font size=2 face="sans-serif">After a bit of debugging I managed to
resolve my issue. It appears the correct way to resolve this issue is to
instantiate an instance of PackageBuilderConfiguration and pass into the
constructor a Properties object where you specify your options.</font>
<br>
<br><font size=2 face="sans-serif">Spring configuration:</font>

<br><font size=2 face="sans-serif">Next, this PackageBuilder must be set

Hi Mark,</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
Thanks for the reply. I created a packagebuilder.conf file that simply
had name/value pairs in it as follows:</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
drools.dialect.java.compiler=JANINO</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
and I placed into one of each of the following locations:</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
WEB-INF</font><font size=3> </font><font size=2 face="sans-serif"><br>
WEB-INF/classes</font><font size=3> </font><font size=2 face="sans-serif"><br>
META-INF</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
I tried each one, one after the other but I still receive the same error
message at application startup. Do I have the entries correct? Should I
be placing this somewhere else? Is there something that I am still overlooking?</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
Thanks for the help...</font><font size=3> </font><font size=2 face="sans-serif"><br>

I'm using JBoss Rules 4.01 with Spring 2.5 and I'm utilizing the JSR-94
interfaces provided by Spring Modules. When deploying my application I
receive the error:</font><font size=3> </font><font size=2 face="sans-serif"><b><i><br>
<br>
The Eclipse JDT Core jar is not in the classpath</i></b></font><font size=3>
</font><font size=2 face="sans-serif"><br>
<br>
I've searched through the postings and found that setting the compiler
to </font><font size=2 color=#4200ff face="Courier New">drools.dialect.java.compiler</font><font size=2 face="sans-serif"><b><i>
</i></b>should resolve the issue but I am having trouble figuring out where
to set this property on the JSR_94 interfaces. I've tried passing a Map
into</font><font size=3> </font><font size=2 color=#0021bf face="Courier New"><br>
<br>
ruleAdministrator</font><font size=2 face="Courier New">.getLocalRuleExecutionSetProvider(</font><font size=2 color=#0021bf face="Courier New">providerProperties</font><font size=2 face="Courier New">);</font><font size=3>
</font><font size=2 face="Courier New"><br>
<br>
with the following specified in my Spring configuration:</font><font size=3>
</font><font size=2 face="Courier New"><br>
</font><font size=2 color=#008080 face="Courier New"><</font><font size=2 color=#3f8080 face="Courier New">prop

</font><font size=2 face="Courier New"><br>
<br>
but I believe the initialization occurs long before this point. <br>
<br>
I've also tried dropping into the applications WEB-INF/lib directory a
copy of the jasper-compiler-jdt.jar into the WEB-INF/lib directory, which
should satisfy the dependency, but it didn't seem to resolve the issue.
</font><font size=3><br>
Either that's the wrong classpath location, or that jasper compiler isn't
hte same thing, try the jdt.jar supplied with drools. </font><font size=2 face="Courier New"><br>
I would prefer it if there was some way of setting this property without
having to use the JDT libraries. </font><font size=3><br>
This should be possible, have you tried adding a packagebuilder.conf to
tbe WEB-INF directory as the propperties loader checks for one of those
first. </font><font size=2 face="Courier New"><br>
<br>
I saw that I can provide system properties to make Drools aware of the
req</font><font size=2 face="sans-serif">uested compiler setting but this
is not really an option as I am running inside of a J2EE container and
I am unable to modify the settings that are provided to the application
server. Is there a default location in the classpath that Drools looks
for a properties file that I can specify these values? Or better still,
is there a way that I can supplied them to the JSR-94 interfaces to ensure
proper initialization?</font><font size=3> <br>
no and it is for this reason that I tell people to stay away from the abomination
that is JSR94. </font><font size=2 face="sans-serif"><br>

Thanks very much for the help.<br>
