I am writing a Google App Engine app using Java that uses 3rd party libraries. I am getting a "java.lang.NoClassDefFoundError" when running the app when it hits the line with references to the 3rd party library. This app works when creating a normal servlet, so I am pretty sure the code is correct. I am developing in Eclipse. Does th...
Hi, I'm developing j2ee app on glassfish v3 which will remotely call EJB deployed on jboss 5 app server. For this to work, my app has to have jboss client jars in class path. I managed to do this by packaging client jar files with my application, but this expends size by aprox 10mb, thus uploading app becomes an issue. How can I put th...

Hello, I have a "core" application that is adapter to process task. Each task is implemented in an adapter load by the core to process the task. My question is, is it possible to have different classpath in each adapter to precent class/jar conflict between adapters. Regards, ...
We have a Java product that uses a lot of FOSS/COTS software. A number of our "externals" use the same jar product, but a different version. For example, Ant 1.6.5 and Ant 1.7.0; or multiple versions of xerces. What's I'm concerned about is that the behavior of our application may change or worse, epic fail if we change the order in whic...

Then I will place this file in glassfish lib dir so that jars mentioned become in classpath for application. the only problem is I dont know how to create this single ja...

Are there any disadvantages in using Java 6 wildcards in my classpath ? e.g. C:> set CLASSPATH=.\lib\* I can see that where there are two jars that both contain a class with the same path then using a wildcard may lead to results that are hard to track down. But other than that, is there anything else to be aware of? ...
In our project we use Eclipse launch configurations which are under version control to be shared with all developers. Now it is necessary to include an external archive to a launch configuration file's classpath. Fortunately the required archive is in every developer's local Maven repository. I already found out that there is a classpath...

E.g. the test c...
Complied Mahout successfully under Windows using Maven. I'm trying to run one of the examples from the command line and I don't get what I am doing wrong. Seems like a CLASSPATH problem. Let's say I want to run the GroupLensRecommenderEvaluatorRunner example. I go to the folder with the GroupLensRecommenderEvaluatorRunner.class file ...

So I'm working on a java project (an exitsing java project that uses maven2, not mine). Everything works fine. I add a new class to the source directory. I do mvn compile and get success. I then do `mvn exec:java -Dexec.mainClass="package.NewClass" and get classNotFoundException. It does compile the new file, and I can see the NewCla...
Apart from JNDI, is there any real use for a context class loader? Is there any real NEED for a context class loader? If I fail to set the context class loader, what will break? Yes, I know that magic Java services mechanism with the file in /META-INF/ will break, but I think that's poor design, so it deserves to break... anything else...
I've built a JAR file and it executes fine on my PC (XP) which has Eclipse installed. It also works on another PC, which also has Eclipse. I've tried running it on another PC(XP) that does not have Eclipse. Though it contains the JDK and multiple JRE. The JAR file just does not execute by clicking or from the command prompt. I am not ...
I have seen this: <classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources"/> In my Eclipse .classpath file many times when creating a new Maven project, but I can not seem to figure out - what in the heck does excluding="**" mean? EDIT: I guess what I am trying to get at here, is that though it seem...
