It doesnt give any exception.
Just that if I hardcode the merge and dest dirs it generates the files properly.

The below ant task in build.xml is failing to generate web.xml and struts.xml to the corresponding dir.
Please help with fixing this issue.


<xdoclet> <!-- defines the file handled by xdoclet2 --> <fileset dir="${src.dir}"> <include name="**/*Action.java" /> </fileset> <!-- defines the processing of a plugin --> <component classname="org.xdoclet.plugin.web.WebPlugin" destdir="${web.dd.dir}" mergedir="${merge.dir}" validate="false" /> <component classname="com........plugin.XWork2XMLPlugin" destdir="${web.dd.dir}/classes" mergefile="${merge.dir}/struts.xml" validate="false" /> </xdoclet>

Hi,

For my current project an HQL is taking over 8 min to excute.
Is there some way to optimize this query and bring the execution time down?
the hql is like as shown below:

<query name="a_query_name"> select obj from OBJ as obj left join fetch obj.a1 left join fetch obj.a2 left join fetch obj.a3 where obj.isCurrent = true and obj.isActive = true and obj.status != 'New' and obj.someType = 'ABC' </query>

Rik,
Your question is not clear.As far as what u asked it is not possible to convert a BufferedReader variable into int bcoz first one is an object and second one is a primitive type and ia not compatible.
But if u want to perform swtich depending on the characters read from the stream the you can safely use the read() method which returns an int representation of the next available character in the stream...

Hi Anshuman,
Can u plz differentiate between daemon n non daemon threads?
Manoj

Micheal,
Can u elaborate on the issue?

Anshuman,
Protected members(variables as well as methods) are accessible within the class in which they are defined and their subclasses.Yes any class which doesn't extend from any oyther class implicitly extends from Object class.Hence anyhow your class inherits the finalize() method of Object class.So their is nothing to worry about packages while dealing with Object class's resources!! ok?
