Hello,
After migrating from gwt 1.5.3 to 1.7.0 I encountered severe problems:
I'm starting my gwt shell as follows:
javaw.exe -classpath slf4j-api-1.5.2.jar;slf4j-log4j12-1.5.2.jar;...
com.google.gwt.dev.HostedMode -startupUrl ...
After startup I get a NoClassDefFoundError when my application tries
to load a slf4j class.
As far as I know there are two solutions to this issue:
1. Copy the relevant jar file to war/WEB-INF/lib
2. Use a custom JettyLauncher (via -server arg) and change
JettyLauncher$WebAppContextWithReload
$WebAppClassLoaderExtension#isSystemPath like so:
public boolean isSystemPath(String name) {
name = name.replace('/', '.');
return super.isSystemPath(name)
|| name.startsWith("org.apache.jasper.")
|| name.startsWith("org.slf4j.")
|| name.startsWith("org.apache.xerces.");
}
Both solutions mean a great deal of additional work everytime my
dependencies change and are therefore merely a workaround but no
solution.
Wouldn't it be nice to be able to use all the classes defined by the
classpath at runtime?
This wasn't a problem in gwt 1.5 using tomcat.
What can I do?
Best regards
Robert
