Java Compiler Cannot Find the Required JAR File in the Classpath
I posted this problem before. Max and Carey answered my post right away. I tried and tried I must be missing something. I really do not understand why all of a sudden that the java compiler cannot find the required JARs in the classpath. I have done some similar compilation before successfully. My head is not sober enough to pinpoint the problem this time. I am doing the compilation manually (I am not using ANT or any IDE). 1. I have the commons-scaffold.jar in my $TOMCAT_HOME/webapps/PracticeVersion/WEB-INF/lib folder. 2. I have the struts.jar in both $TOMCAT_HOME/webapps/PracticeVersion/WEB-INF/lib folder and j2sdk1.4.1_02/jre/lib/ext folder 3. in my java program (Bean.java), I import org.apache.commons.scaffold.text.ConvertUtils; import org.apache.commons.scaffold.util.ProcessBeanBase; import org.apache.commons.scaffold.lang.Tokens; 4. I first set the classpath C:\>set CLASSPATH=C:\jakarta-tomcat-4.1.18-LE-jdk14/webapps/PracticeVersion/WEB-INF/src/java;%CLASSPATH% then, I go to the folder where Bean.java is C:\>cd jakarta-tomcat-4.1.18-LE-jdk14/webapps/PracticeVersion/WEB-INF/src/java/org/apache/artimus/article then, I try to compile and put the class file in the destination folder C:\jakarta-tomcat-4.1.18-LE-jdk14/webapps/PracticeVersion/WEB-INF/src/java/org/apache/artimus/article>javac -d C:\jakarta-tomcat-4.1.18-LE-jdk14/webapps/PracticeVersion/WEB-INF/classes Bean.java But, I get compilation error: package org.apache.commons.scaffold.text does not exist package org.apache.commons.scaffold.util does not exist package org.apache.commons.scaffold.lang does not exist __ Do you Yahoo!?

Re: Java Compiler Cannot Find the Required JAR File in the Classpath
put commons-scaffold.jar folder on your classpath before compiling e.g. SET CLASSPATH=DirectoryWhichContainsCommons-Scaffold.jar;%CLASSPATH% Hth, Martin - Original Message - From: "Caroline Jen" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, October 20, 2003 6:50 PM Subject: Java Compiler Cannot Find the Required JAR File in the Classpath > I posted this problem before.

Re: Java Compiler Cannot Find the Required JAR File in the Classpath
This might not solve your immediate problem, but someone responded to your original thread that you need to pull struts.jar out of the JDK's ext dir. Trust me, you really need to do this, at least if you're going to deploy multiple web applications using Struts in the same servlet container, and it's just generically good practice. But if I might offer a suggestion, it might be a really good idea to spend a little bit of time learning Ant. It's really ideally suited for this, and by having a script setup which will produce the proper classpath for your application, you can make sure that you don't have cases where all of a sudden things stop working. It's also easy to say things like "compile everything in this directory, and use all the .jar files in this other directory in the classpath". Just a tip. It won't get you over the initial hangup, but it's probably something you should investigate for the future. Kirk Wylie M7 Corporation Caroline Jen wrote: I posted this problem before.

Re: Java Compiler Cannot Find the Required JAR File in the Classpath
Hi copy the required jar files inthe current dir. Always the best way is set classpath= make it blank set the new classpath in which set the classpath of copied jar files of current dir. then no problem. Make this habit after compilation delete the jar files (if not required). This is the best practice of working with JAVA Compilers. and work with command prompt not any editor. it confuses us. thankx & regards abhijeet - Original Message - From: "Kirk Wylie" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Tuesday, October 21, 2003 11:07 PM Subject: Re: Java Compiler Cannot Find the Required JAR File in the Classpath > This might not solve your immediate problem, but someone responded to > your original thread that you need to pull struts.jar out of the JDK's > ext dir.
