I tried the Java Preferences API, but it won't let you access registry entries. It will only let you read/write to registry entries that you create specifically for your Java application, based on the Java package.
So, I tried orangevolt, but I get this error: BUILD FAILED C:\MIAEnterpriseSystem\Delivery8.0\build.xml:40: taskdef A class needed by class com.orangevolt.tools.ant.Win32ShortcutTask cannot be found: com/roxes/win32/UrlFile I tried taking Peter Kitt's advice by putting the orangevolt-ant-tasks.jar file into %USERPROFILE%/.ant/lib. But, no such directory exists in my C:\Documents and Settings directory. When I tried to create the .ant directory, Windows 2000 gave me this error: You must type a filename. So, I tried adding the orangevolt .jars to my classpath with no success. Here's the snippet from my build file: <path id="build.classpath"> <pathelement location="${classes.dir}/easserver.jar" /> <pathelement location="${classes.dir}/easj2ee.jar" /> <pathelement location="${classes.dir}/easclient.jar" /> <pathelement location="${classes.dir}/jconn2.jar" /> <pathelement location="${classes.dir}/orangevolt-ant-tasks-1.3.5.jar" /> <pathelement location="${classes.dir}/roxes-win32forjava-1.0.4.jar" /> <pathelement location="${java.home}/lib/tools.jar" /> <pathelement location="${classes.dir}" /> <pathelement location="${src.dir}" /> </path> <taskdef classpath="build.classpath" resource="com/orangevolt/tools/ant/taskdefs.properties"/> <target name="orangevolt" description="Check for EAServer's classpath"> <!-- Look for HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Jaguar/Parameters/CLASSPATH --> <win32.registry root="HKEY_LOCAL_MACHINE" key="SYSTEM"> <exists property="test" subkey="CurrentControlSet/Services/Jaguar/Parameters" entry="CLASSPATH" /> </win32.registry> <echo message="test=${test}" /> </target> What am I doing wrong?

On initial load, the tasks copy the dll into $JAVA_HOME/jre/bin. The tasks can then read and write reg entries. Usage: drop the orangevolt-ant-tasks.jar file into %USERPROFILE%/.ant/lib and use: <project name="rox" default="main"> <taskdef resource="com/orangevolt/tools/ant/taskdefs.properties"/> <target name="main"> <win32.registry root="HKEY_LOCAL_MACHINE" key="SOFTWARE"> <!-- softwareExists will be set if HKEY_LOCAL_MACHINE\SOFTWARE exists --> <exists property="softwareExists"/> </win32.registry> <echo message="softwareExists=${softwareExists}"/> </target> </project> Peter > Thanks, > > Bob > > Robert Pepersack > Senior Lead Developer > Maryland Insurance Administration > 410-468-2054 > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
