Unable to compile under JDK1.5

[jayram joshi]

Hello

I am trying to port a project from JDK1.4 to JDK1.5. During compilation I get following errors

1. package org.apache.xpath.patterns does not exist
2. package org.apache.xml.utils does not exist
3. package com.sun.rsasign does not exist import com.sun.rsasign.c;

I think they were removed from JDK. Can anyone throw some light on where to find respective jars so that the compilation will go through

Thanks

All the packages you mention are not part of the JDK, and also not under Java 1.4.

Your application uses some libraries, make sure that you include all the needed libraries in the classpath. It's not different from Java 1.4. Are you now compiling your classes differently than when you were using Java 1.4? Why?

I am certain they are part of JDK1.4. When I look into rt.jar I can see them. But they are missing from JDK1.5's rt.jar.

Hi, jayramj,

Welcome back to JavaRanch! Please adjust your display name to meet the JavaRanch Naming Policy that has gone into effect since you were last here.
You can change it here.

I think rt.jar is part of the jre and not the jdk (but I could be wrong about that).

for the first two.

Another option would be to extract the necessary jars from the rt.jar and put them into your project.


Jarhoo is a good resource to know about.

I checked; these classes are indeed in rt.jar of Java 1.4.

But since these classes are not mentioned in the API documentation of J2SE 1.4, you should not have used them in your application. They are not part of the official API, so Sun can remove them as they like in a new version.

Read this, it applies not only to com.sun.* packages but to any package that's not part of the official, documented API:
Why Developers Should Not Write Programs That Call 'sun' Packages

You need to re-write your program so that it isn't dependent on undocumented packages.

Thanks Guys. I guess I will have add respective jar files to classpath
Yes I agree one shouldnt use undocumented classes. But I am one of those unlucky ones who needs to work on code I didnt write
