Solution |
|
The " java.lang.ClassNotFoundException" can occur while starting the client. This exception occurs when classes from the crimson.jar, jaxp.jar and xalan.jar were not present in the classpath. |
To overcome this exception, please follow the endorsed mechanism as per steps given below:
1. Copy xalan.jar, crimson.jar, and jaxp.jar (from earlier version of JDK say 1.4) to a folder, for example \"endorsed_nms\" under <Web NMS Home>/classes folder.
2. In the <WebNMS Home>/setEnv.bat/sh file, add the below content. -Djava.endorsed.dirs=%WEBNMSHOME%\\classes\\endorsed_nms
3. Now in the server startup script (<WebNMS Home>/bin/startnms.bat/sh) use the following line for invoking the startup class. %JAVA_HOME%\\bin\\java -Xmx200M -Djava.endorsed.dirs=%WEBNMSHOME%\\classes\\endorsed_nms
4. Now start the client and try connecting to the server.

Scenario 1 :
javax.xml.transform.TransformerException: java.io.FileNotFoundException: file:\C:\Program%20Files\AdventNet\WebNMS\NetMonitor\build\uninstall.xml (The filename, directory name, or volume label syntax is incorrect) at org.apache.xalan.transformer.TransformerIdentityImpl.createResultContentHandler (TransformerIdentityImpl.java:260) at org.apache.xalan.transformer.TransformerIdentityImpl.transform (TransformerIdentityImpl.java:291)
Scenario 2 :
java.net.MalformedURLException: unknown protocol: c
These above two exceptions occurs when there is a space in the directory path where WebNMS is installed and trying to install a NAR file in WebNMS. This is a JDK bug which occurs in some scenarios where Xalan parsing of XML file is done.
|
Kindly install the WebNMS in a directory which does not have space characters in its path. |
